2.1 Using the Application

...

The program can now be opened by going to the start menu and selecting "Programs" then "Aptina Imaging" then "DevWareDevWareX". A popup window will appear while DevWare DevWareX probes for attached devices. Then the main DevWare DevWareX window and a dialog box will appear that is slightly different for each sensor. Select the appropriate settings and click finish. Unless an error occurs(See 2.2.17) the application will open the display dialog and start capturing and displaying sensor images.
Note: Sensor data files can be manually loaded. Click the esc key to exit automatic probe. Make sure that the box next to "Automatically probe at startup" is unchecked. Click on "Sensor..." to browse for the corresponding sensor data (sdat) file. The file will be found in C:\Aptina Imaging\sensor_data.

...

DevSuite is ready to use on the Vista and Windows 7 operating systems when installed in the correct folder, but there is a requirement that the Demo2X demo board have a FW version of 28 or newer to match to the USB driver.
Note; the Demo3 FW is already Windows 7 compatible.
Firmware Upgrade
Note that a demo board with FW older than version 28 can only be upgraded on an XP operating system since only the XP-based USB driver supports the older versions of the FW. As of May of 2010, all newly delivered Demo2X boards will have version 28 of the FW. Demo2X boards received earlier than that may have an older FW version, and the FW version should be verified on an XP-based system before proceeding.
If you aren't sure that your FW has version 28 or newer, install the DevSuite SW on an XP-based system by following the instructions thru the section titled "Starting Up the Software" as found in "DevSuite Quick-Start Guide", which can be accessed from the DevWare DevWareX menu item "Documents". Then follow the FW upgrade instructions as found in "Demo FW User Guide", which can be accessed from the DevWare DevWareX menu item "Documents -> User Guides".
If you are fairly sure that your FW has version 28 or newer, then install the DevSuite SW on your Vista or Windows 7-based system by follow the instructions thru "Starting Up the Software" section of the Quick-Start guide. Once the USB cable is connected to the Demo2X demo board, Vista and Windows 7 will automatically attempt to download the matching USB driver from the Microsoft driver web site; if the driver installs correctly then your FW is current and no further action is required - continue with the instructions found in the Quick-Start guide.
If the USB driver download fails, it is either due to downgraded FW or a network problem. You can attempt to load the USB driver manually by following the instructions in the "Aptina Drivers User Guide", which can be accessed from the DevWare DevWareX menu item "Documents -> User Guides".
If the USB driver installs correctly then your FW is current and no further action is required - continue with the instructions found in the Quick-Start guide.
If the USB driver manual load failed, you will need to use an XP-based operating system to upgrade your Demo2X demo board as described earlier in this document. 
Software Installation
Do not install DevSuite in "C:\Program Files", due to the strict system security checking performed by Vista and Windows7.
The installer defaults to the recommended installation location of "C:\Aptina Imaging". If necessary this can be changed when prompted for the installation location.

...

Command line parameters can be used with DevWareDevWareX.
Usage
Open a "CMD" window, navigate to the installation folder of C:\Aptina Imaging, and provide any of the following parameters.Note that parameters can be in all upper-case or all lower-case, and can be provided in any order.

...

• /help or ? - Display this page.  You are given the option to continue to DevWareX or to exit.  Note: if "?" is used, all other parameters are ignored.
• /ini=filename or /ini="filename" - Specify the INI file to be used, overriding the one selected by DevWare DevWareX if "Probe" is enabled.
• /preset[=name] or /preset[="name"] - Run the optionally supplied specified preset. Note that the Startup Wizard dialog will be skipped whether or not the preset name is supplied.
• /checksensor[=0 | 1 (default if not supplied)] - Disable | Force reading of sensor registers at startup. Disabled gives faster startup.
• /camera=<number in decimal> - Force a specific camera id selection, in case more than one camera was detected.
• /probe[=0 | 1 (default if not supplied)] - Disable | Force a "Probe". Note: ignored if SDAT filename is provided, and no "Probe" is performed if the parameter itself is not supplied.
• /fullauto[=0 | 1 (default if not supplied)] - Disable | Force "Full Auto" option on the Startup Wizard. Note: enabled if parameter itself is not supplied.
• /mono[=0 | 1 (default if not supplied)] - Disable | Force "Monochrome" option on the Startup Wizard. Note: disabled if parameter itself is not supplied.
• /play[=0 | 1 (default if not supplied)] - Disable | Force "Play on Start" option on the Startup Wizard. Note: enabled if parameter itself is not supplied.
• <sensor_sdat_file>.sdat - Specify the SDAT file to be used, overriding the one selected by DevWare DevWareX if "Probe" is enabled.
• /nul - start without HW needing to be attached. An SDAT file can be loaded, and Presets can be run as long as it doesn't expect register reads to provide valid data.
• /detfar - detect FAR sensor on start.
• /warnings=filename - Specify the warnings file name.
• /restorepresets - 1 to restore the additional Presets windows from the last session, 0 to not restore the windows.

2.2.1.1 About Plug-ins

Introduction
The DevWare DevWareX application framework includes the ability to extend and customize its behavior.  Two types of extensions are supported:

1. Dialog Plug-in - a dynamically linked library (DLL) which can be integrated with DevWare DevWareX and can be used to:
   • Display custom user interfaces.
   • Access and run DevWare DevWareX INI presets.
   • Access sensor registers.
   • Process the image data.

...

1. Midlib Transport DLL - a DLL which can be integrated with the midlib library in order to create a "driver" for midlib/DevWare DevWareX in order to support new devices.  With a midlib Transport DLL you can:
   • Support an ON Semiconductor sensor on a device other than the Demo System camera so DevWare DevWareX or any other midlib-based application will work with the device.
   • Create a software simulated camera and sensor, simulating either an existing sensor or new sensor, and be able to use DevWare DevWareX as the user interface for the simulation.

...

The toolbar is displayed across the top of the application window, below the menu bar. The toolbar provides quick access to many tools used in DevWareDevWareX.
To hide or display the Toolbar, choose Toolbar from the View menu (ALT-V, T).

There are two distinct modes of still capture. In the Current Displayed Image mode the still capture only freezes the currently displayed image and lets you save it to a file. No sensor registers are affected.
In the Full Resolution Image mode DevWare DevWareX will perform a still capture procedure on the sensor. It could involve changing the image size, using global shutter mode, activating a flash lamp and so on. On an SOC it would involve activating the still image sequence on the sensor.

Still Image Format

For 20-bit depth, each pixel occupies 4 bytes, stored LSB first. The pixel value is in the 20 low bits.
For compressed formats, our software by default expands the pixels before saving the RAW file, so the RAW file has linear data.

2-byte covering 12-bit words:   (1 2 3 4   5 6 7 8) (9 10 11 12    0 0 0 0)
4-byte covering 20-bit words:   (1 2 3 4   5 6 7 8) (9 10 11 12    13 14 15 16) (17 18 19 20    0 0 0 0) (0 0 0 0    0 0 0 0)

Snapshot Page
Select various options related to still image capture. Note that "Average into One Frame" does not work with JPEG output format.  The Average is pixel-wise temporal mean.

AnchorimagesaveoptionsimagesaveoptionsImage Save Options Page
This dialog is used to set the various image save options that are available.
The "Save Options" selection allows the user to select the type of data to be written to files. Raw Data is the unprocessed data coming from the sensor, which will be in the format the sensor is outputting, for example Bayer or YCbCr data. The Processed Data is RGB output data which has been converted from Bayer or YCbCr by DevWare. The image will also include any of the image processing pipeline that has been enabled. The Processed Data can be saved in either a 24bpp Bitmap file or 48bpp TIFF file. By default the register information is saved in the accompanying .TXT file.
Also available are the options on where to save the images. Note; if both "Auto File Name Increment and Save" and "Hold Still Image in Main Window" are disabled, the "Grab" and "The software is transport-independent and supports parallel, HiSPi, and other interface types that don't even have a byte-wise representation.
MIPI is byte-wise, but the FPGA on the Demo3 parses the MIPI stream and unpacks the pixels. There is no way to get the MIPI stream exactly as it comes from the sensor.

RAW still files are always 8-bit, 16-bit or 32-bit per pixel. If the bit depth is not one of those values, then the smallest format big enough to hold the data is chosen and the data is in the least significant bits
This is how the data normally comes across from the device driver, and also has the advantage that it's easy to read with various software libraries and tools (Matlab, numpy, etc.).

Video Record Page
To capture a video stream press the Record button on the Toolbar(See 2.2.2).
NOTE: If Capture to RAM is unchecked, video is streamed directly to disk. The performance will depend on the speed of the hard disk and could result in dropped frames.
NOTE: The video formats are uncompressed and will take a significant amount of hard disk space.
NOTE: If Preview is disabled then the Color Pipe functions are skipped while live frames are accumulating. There will be no AE, nor any other Color Pipe processing.
You can save data in MPEG-4, AVI (2GB limit), WMV, or RAW format. RAW format requires no image processing and usually takes less disk space. If you don't have a compatible WMV codec installed, you'll be prompted with a URL to download one when you select that format. 
You can also save data as "PNG Raw Files" or "PNG RGB Files", which is the ability to save a video as a sequence of PNG files in either Raw or RGB format. Note that Raw only supports Bayer or similar (not YCbCr).You can use WMV instead of AVI for unlimited file length. DevWare does not use compression with AVI. Usually the codec is just RGB-24. WMV is compressed in softwaresimilar (not YCbCr).

You can use WMV instead of AVI for unlimited file length. DevWareX does not use compression with AVI. Usually the codec is just RGB-24. WMV is compressed in software.

• There is a frame rate value stored in the wmv file. There is a check box and numerical entry on the Sensor Control -> Video Record dialog page where you can provide a frame rate to put in the file. If that is not checked DevWareX uses the Display FPS.
• But that value comes from before recording started. During recording there could be considerable disk overhead or compression overhead so that the actual frame rate during recording is lower than it was before recording started. In that case the frame rate in the file will not match the actual frame rate of the recording.

The compression quality for MPEG-4 or WMV recording can be controlled with the "VidCap Quality" STATE variable.

...

• RAW files will play back in DevWareDevWareX, but will need to be converted to AVI to be imported into other applications. You can use DevWare DevWareX as a RAW to AVI file converter. Load the RAW file in DevWare DevWareX and verify that the image looks correct. On the Video Capture dialog page select AVI recording format and turn off Capture to RAM. Click the Stop button on the Toolbar(See 2.2.2). Click the Record button on the Toolbar(See 2.2.2).
• The "Frame rate" listed in the info.txt file (RAW only) is the rate displayed on the Info Panel "FPS (Display)".
  A specific frame rate can be set via Sensor Control / Video Record "Specify playback frame rate", or via the INI file using the STATE commands "VidCap Auto Play FPS" and "VidCap Play FPS".
• “Specify playback frame rate”; DevWareX video playback speed is not precise.
• MPEG-4 requires at least 20 frames to be recorded. 

Single Button Image Capture
To enable the ability to perform a single-button image capture, do the following;- On the "Snapshot" page, enable "Camera Sound Effects". - On the "Image Save Options" - Use <F9> (for a "Grab") or <Ctrl-F9> (for a "Snapshot") to capture an image with a single button.

2.2.4.7 Diagnostic Pages

Noise Measurement PageMeasurement Page and Noise vs. Exposure

User Guide can be found here.

The Noise Measurement tool runs a series of noise analysis computations, and reports signal levels and different kinds of noise measurements.
After the analysis completes, the results are displayed here in plain text, tab-separated format.

...

A report will look something like this:
Noise Levels (std. dev.) Signal Full Range = 255
Channel Signal RMS Dyn Avg Dyn FPN Col FPN Row FPN Col Dyn Row Dyn
Y 128.0 0.674 0.669 0.340 0.112 0.218 0.540 0.546

Cr 128.6 0.505 0.502 0.282 0.101 0.079 0.200 0.213The formulas for the calculations are as follows. The noise measurement process captures N frames of W x H pixels, creating a 3-dimensional data set of W*H*N pixel values. Pixel values are denoted as
p(x, y, i) wherex = 0 .. W-1y = 0 .. H-1i = 0 .. N-1
Define also the following intermediate values:
p_avg(x, y) = [Σ p(x, y, 0..N-1) ] / N
σ(x, y) = sqrt( [Σ (p(x, y, 0..N-1) - p_avg(x, y))² ] / N)
h(y, i) =  [ Σ p(0..W-1, y, i) ] / W
h(y) =  [ Σ p(0..W-1, y, 0..N-1) ] / (W*N)
v(x, i) =  [ Σ p(x, 0..H-1, i) ] / H
v(x) =  [ Σ p(x, 0..H-1, 0..N-1) ] / (H*N)
The analysis results are calculated as follows:
Signal = [Σ p(0..W-1, 0...H-1, 0..N-1) ] / (W*H*N)
RMS Dyn = sqrt( [Σ σ²(0..W-1, 0..H-1) ] / (W*H) )
Avg Dyn = [Σ σ(0..W-1, 0..H-1) ] / (W*H)
FPN = sqrt( [Σ (p_avg(0..W-1,0..H-1) - Signal)²] / (W*H) )
Col FPN = sqrt( [Σ (v(0..W-1) - Signal)² ] / W )

The Info dialog appears at the left edge of the DevWare window and displays information about the image sensor, the frames displayed and the mouse position. Additionally, it has list box controls to change the mouse selection area (for use with the Analysis Dialog(See 2.2.9)) and to select between multiple sensors (only appearing if more than one sensor is attached).
Property fields:

...

Sensor

...

The ON Semiconductor Imaging sensor being used.

...

Part number

...

The ON Semiconductor part number for this sensor.

...

Sensor version

...

The version of the image sensor.

...

Sensor type

...

Either 'Bayer' or 'SOC' sensor.

...

Software:

...

Build name

...

The version and type of build (either Release or Beta).

...

Build version

...

The full version number (major.minor.revision.build) of the DevWare application.

...

Build date

...

Date the software was compiled. (MM/DD/YYYY)

...

Demo Board:

...

Type of Demo board being used (for example: DEMO2X or DEMO3).
Note: The FPGA version is displayed in parentheses.

...

Firmware

...

The version of the Firmware code on the Demo board.

...

Array Clock

...

The oscillator frequency being used (in MHz).
Note: This value can be modified by the user through the Options Dialog(See 2.2.15).

...

Pixel Clock

...

The pixel clock output as calculated by DevWare based on the specific configuration of the attached device.
It is intended to be the pixel rate at the sensor output.
DevWare has different ways of deriving clocks from each other.  In most cases, array clock was derived from external clock, and then pixel clock was derived from array clock.

Array Clock is nominally the sensor array clock. It's the clock used to calculate row time, exposure time, etc.
Pixel Clock is PIXCLK for the parallel interface, or the pixel rate. There is also Input Clock which is the clock input to the sensor.

Normally, the clock rates are re-measured when a PLL register is changed. Depending on the demo kit configuration, it may not be possible to measure the clocks from software. Demo2X can measure PIXCLK if the sensor is streaming in parallel mode. Demo3 can measure Input Clock if it is hooked up to the Demo3 clock sense line. Once one of the clocks is measured, the other two can be calculated from the PLL settings.

The clock speed on the Options dialog sets the Array Clock value (in case DevWare can't measure it), and Pixel Clock and Input Clock will be automatically calculated according to the PLL settings.

...

Width

...

The pixel width of the displayed sensor image.

...

Height

...

The pixel height of the displayed sensor image.

...

Format

...

The current sensor image format (for example 'YCbCr', 'Bayer 8', 'Bayer 10', etc.).

...

Frames

...

A frame counter that gets increased for each displayed sensor image.

...

Dropped frames

...

Dropped frames are possible under the following circumstances:

• The application couldn't determine the end-of-frame because of a change in the data flow (this is not a sensor issue).
• The image data is sent faster then the computer can handle. This can happen on slower PC's/laptops or when other applications are slowing down the computer.
  To view the dropped (incomplete) frames regardless, go to the Options Dialog(See 2.2.15) and enable 'Debug Mode (show dropped frames)'.

...

FPS (Sensor)

...

The computed number of Frames Per Second that the sensor is running at based on register settings and oscillator (see Clock above) value.
Note: SOC sensors dynamically change the frame rate for exposure purposes. To update the FPS number click the 'Refresh' button at the bottom of the main Sensor Control dialog(See 2.2.4).

...

FPS (Datalink)

...

The number of Frames Per Second that the camera sends to the host computer via USB (or other data link). This number can be influenced by the speed of the computer, or the host controller and drivers.

...

FPS (Display)

...

The number of Frames Per Second that are displayed on the computer. A camera frame is first converted from its native format (see above) to a 32bit RGB image and finally converted to the display adapter's resolution (preferably also 32 bit). Software image processing can slow down the display frame rate. The display frame rate is also affected by the host computer's display drivers. The Accelerated selection on the Options(See 2.2.15) dialog can help.

...

Cursor pos

...

The mouse cursor position when the mouse is over the display area. Expressed as a positive (width, height) value relative to the upper-right most pixel (0,0).

...

Raw Data

...

The unprocessed sensor data at the mouse cursor position. For SOC sensors the data is separated into Y, Cb, and Cr values. For Bayer sensors there is a single data value, with the Bayer color pattern position indicated in parentheses (R, Gr, Gb, or B).

...

R: Output

...

The value of the Red component of the displayed image at the mouse cursor position.

...

G: Output

...

The value of the Green component of the displayed image at the mouse cursor position.

...

B: Output

...

The value of the Blue component of the displayed image at the mouse cursor position.

Mouse Selection (used in conjunction with the Analysis Dialog(See 2.2.9)):

...

Off

...

No area selected. The whole image is used for analysis.

...

Rectangle

...

Only the selected rectangle is used for analysis (typically used with the analysis-histogram graph).
Note: You can do an Intensity plot in any direction.

...

Column

...

 This dialog can be used to load or save the current state of the sensor registers and color pipe settings. This information is stored within an .ini file which is loaded for each version of the sensor. For example, the file for the MT9V112 REV3 would be located in C:\Aptina Imaging\apps_data\MT9V112-REV3.ini. All sensors have a 'Demo Initialization' preset. Bayer Sensors typically have a 'Color Processing ON' and 'Color Processing OFF' Preset as well.
INI files are plain text and can be edited by the user. See the INI File Users's Guide for more information about ini files and the command syntax.

p(x, y, i) wherex = 0 .. W-1y = 0 .. H-1i = 0 .. N-1
Define also the following intermediate values:
p_avg(x, y) = [Σ p(x, y, 0..N-1) ] / N
σ(x, y) = sqrt( [Σ (p(x, y, 0..N-1) - p_avg(x, y))² ] / N)
h(y, i) =  [ Σ p(0..W-1, y, i) ] / W
h(y) =  [ Σ p(0..W-1, y, 0..N-1) ] / (W*N)
v(x, i) =  [ Σ p(x, 0..H-1, i) ] / H
v(x) =  [ Σ p(x, 0..H-1, 0..N-1) ] / (H*N)
The analysis results are calculated as follows:
Signal = [Σ p(0..W-1, 0...H-1, 0..N-1) ] / (W*H*N)
RMS Dyn = sqrt( [Σ σ²(0..W-1, 0..H-1) ] / (W*H) )
Avg Dyn = [Σ σ(0..W-1, 0..H-1) ] / (W*H)
FPN = sqrt( [Σ (p_avg(0..W-1,0..H-1) - Signal)²] / (W*H) )
Col FPN = sqrt( [Σ (v(0..W-1) - Signal)² ] / W )
Col LFPN = same as Col FPN except Signal is calculated from the nearby columns only, instead of the whole analysis area.
Row FPN = sqrt( [Σ (h(0..H-1) - Signal)²  ] / H )
Row LFPN = same as Row FPN except Signal is calculated from the nearby columns only, instead of the whole analysis area.
Col Dyn = sqrt( [Σ ( v(0..W-1, 0..N-1) - v(0..W-1) )²] / (W*N) )
Row Dyn = sqrt( [Σ ( h(0..H-1, 0..N-1) - h(0..H-1) )²] / (H*N) )

Fuse ID Reader Page
The Fuse ID Reader page is used to get and save the Fuse ID information for each sensor, by reading register combinations specific to each sensor and saving this information.
Sensor Advanced

This dialog allows for override of settings that DevWareX usually determines on its own via reading sensor register settings.

• Sensor; these check-boxes control hard-wired lines from the Demo3 to the sensor; Power, Reset, and Shutdown.
• Sensor Clock Speed; sets the Input clock speed from Demo3 to sensor headboard (assuming the headboard is jumpered for external clock), and Array clock.
  • Use the "Apply" to set the values, and "Detect" to display the current settings.
• Sensor Base Address; use "Detect" to discover the current I2C value, and the pull-down and then "Apply" to assign a new value (where applicable).
• Color Filter Array (CFA); displays the current CFA, and use the pull-down to force the DevWareX ColorPipe to use this CFA.
• Sensor Output; use "Detect" to discover the current width/height and pixel format, and "Apply" to set new ones.
• Check-boxes; use these to change the pixel order/format.

DEMO3

Gives you access and control to features of the baseboard. - The onboard oscillator can be set via the XMCLK field. The "Image Buffers" select the type of buffering used by the Demo3. And "GPIO Pins" allows the enable / disable and level (on/off).

Serial Receiver

This dialog controls the various settings of the image sensor output format to the Demo3.  The actual controls are self-explanatory as it assumes the user knows these advanced settings.

2.2.6 Preset Dialog

 This dialog can be used to load or save the current state of the sensor registers and color pipe settings. This information is stored within an .ini file which is loaded for each version of the sensor. For example, the file for the AR0544CS-REV1 would be located in C:\Aptina Imaging\apps_data\AR0544CS-REV1.ini.

All sensors have a 'Demo Initialization' preset. Bayer Sensors typically have a 'Color Processing ON' and 'Color Processing OFF' Preset as well.
INI files are plain text and can be edited by the user.

See the INI File Users Guide for more information about ini files and the command syntax.

Image Added

INI file and optional Initializer: Location of main INI file on first line, and optional location of Initializer file (for those sensors with separate Python-settings files).

Preset Actions: various actions available for the loaded INI file.

• Open: open an additional INI file.  Same operation as available in "File / Open Additional Presets ..."
• Edit: edit the INI file, using the edit application associated with ".ini" files.

Histogram
The Histogram collects the total amount of pixels (vertical-axis) for each of the possible intensity values (horizontal-axis) for each of the color channels. The histogram is taken over the currently selected area and works best for a small rectangular selection(See 4.4).
Right-click on the graph for more options. To save the histogram data to a file (tab-separated text) right-click on the graph and select Save Graph Data As....
When the histogram is being displayed, if you right-click on the graph and select Show Control Window the following Analysis Graph Controls are available.
By default the histogram data is displayed in Combined RGB mode. The Analysis Graph Controls can be used to display a luminance graph as well. When displaying a luminance graph the user has the option to display additional data characteristics.

The graph calculates approximate mean from the histogram. So the precision is limited by the size of the histogram bins. That's why it says " ~161 ". Likewise for the other statistical calculations on the graph.

Noise
The Noise graph shows the intensity (vertical-axis) of a single pixel for each frame for all color channels. The old values remain so an intensity-over-time (horizontal-axis) graph appears. This display wraps around and shows approximately 640 time slices. The text at the top display computed temporal SNR in dB. (If there is no fluctuation in the data, the readout shows 0.0.)
Additional Data displayed;

Vectorscope
The Vectorscope graph shows the distribution of the chrominance signal in the selected area. You will need to aim the camera at a color reference chart.
NOTE: DevWare DevWareX only uses 8-bit output for Bayer Sensors by Default. To switch to 10-bit output, go to the 'Sensor Output' Bayer Image Sensor Control Pages (See 2.2.4.2)

I have problems starting the application and see one of the following warning message boxes:
Image RemovedImage Added
-> Check if the USB drivers are installed properly. Refer to the driver installation document under "Start>All Programs->Aptina Imaging->Docs->User Guides->USB Drivers User Guide".
--> Check if the cables are attached to the image sensor properly. If the image sensor worked before, unplug-and-plug the cables and try again.
Image RemovedImage Added
--> Check if the application is started from the same place that holds the sensor_data directory (holding the sensor data(See 4.5) files)
The application starts without errors, but there is no image:
--> Some register settings might lead to stop the sensor from sending valid data. Quit the application and reset the sensor by unplugging it and plugging it back in.
My frame rate is really low:
--> The amount of data that is being processed is quite significant or a lot of image processing function are turned on. Reduce the size of the image on the Output Size or Context page of Sensor Control. On the Options dialog, select the Accelerated Display option. Turn off extra image processing. 
When setting registers the application freezes up:
 -->Changing registers on the image sensor might lead to changes in the data flow resulting in unexpected lockups of the application. Terminate the application as best as possible and reset the sensor by unplugging it and plugging it back in.

  3.1 HardwareUpdate Tool

  This is a Window's application that updates the firmware and FPGA code on the ON Semiconductor Imaging baseboard (Demo2X or Demo3). The tool is located in: Start menu -> All Programs -> Aptina Imaging -> Tools .
  
  
  Usage and Tips

...

• Connect two Aptina Imaging Demo cameras to the system. Make sure the cameras are recognized and the drivers are installed.
• Launch SideBySide from the desktop shortcut. The application will automatically start two instances of DevWare DevWareX and size the display windows evenly. The initial startup takes a little more time than normal, but requires no user interaction. Please be patient.
• All DevWare DevWareX toolbars and dialogs are hidden by the application. They can be manually re-enabled if access to a specific control is needed.
• Selecting Quit from the SideBySide control bar will close all DevWare DevWareX instances, it is not necessary to close each one separately.

This only occurs when you hide extra rows. In your table below the only case where you used the 'Hide' option is the right-most column, 'AR0220AT/hidden'. In all other columns you have not used the 'Hide' option, so the 'last row' is 'height' - 1.

Double-click "Mouse Selection" bar to open the dialog that allows setting of up to 8 unique mouse configurations.  Also see "Lock Mouse Selection", here.

Summary

Not using 'Hide' option: 'last row' = 'height' - 1
Using 'Hide' option: 'last row' = 'height' - number_of_hidden_extra_rows - 1

Whether the sensor outputs embedded data rows is different from whether DevWare DevWareX hides them.
