IQWare

IQware is an image quality evaluation tool which was designed to help measure the image quality and create a measuring standard within Aptina as well as between Aptina and customers or partners. It has the following features:

Common image types (bmp, png, jpg, etc.) support
Seamless interconnects with DevWare to capture images using Aptina Sensors
One click graphical reporting into html files
Layout save and load
Quick start menu for first time user
Multi threaded application for parallel measurement tasks

Matlab runtime

Some image quality methods in IQware were developed in Matlab. Therefore, Matlab runtime is needed to be installed to use those tuning methods. Due to the installer size, Matlab runtime installer is not part of DevSuite installer. When SensorTune is launched and if necessary Matlab components are missing, you will see the following warning.

Users can visit the link presented in the dialog to download and install the necessary Matlab runtime.

Three main modules are supported:
