3 - Advanced Spectral Sensitivity Color Calibration

Input arguments and calibration per iteration

Input arguments

IR filter transmittance data

Typically, the IRCF data is obtained by the following methods:

Measured (e.g., the entire module with lens)
Manufacturer’s data sheet
Assumed standard spectral profile based on the wavelength cutoff (e.g., 650nm, 670nm, etc.)

The data file should be a text file with two columns of numbers, the wavelength in nm, and the transmittance percent. Example:
360 3.79

370 4.08

380 23.72

390 80.95

...

Illuminat data [Optional]

Illuminat can be chosen from drop down menu or users can load their own illuminant spectral data. The data format is the same as the IR and lens transmittance data.

Sensor sensitivity data [Optional]

SensorTune uses internal sensor sensitivity and lens transmittance data, but you can load your own data optionally.

The spectral data should be in the following format:
wavelength, relative response red, relative response green, relative response blue ...

The Quatumn efficieny data should be in the following format:
wavelength, QE red, QE green, QE blue ...

A special care is needed to make sure that there is only one green column. Red green and blue green should be averaged. For the case of clear pixels, green column represents clear pixel response.

Simulated Image [Optional]

An image can be loaded in order to visualize the calibration effect.
