2021-04-22ipa: ipu3: Add support for IPU3 AWB algorithmJean-Michel Hautbois
The IPA will locally modify the parameters before they are passed down to the ImgU. Use a local parameter object to give a reference to those algorithms. Inherit from the Algorithm class to implement basic AWB functions. The configure() call will set exposure and gain to their minimum value, so while AGC is not there, the frames will be dark. Once AWB is done, a color temperature is estimated and a default CCM matrix will be used (yet to be tuned). Implement a basic "grey-world" AWB algorithm just for demonstration purpose. The BDS output size is passed by the pipeline handler to the IPA. The best grid is then calculated to maximize the number of pixels taken into account in each cells. As commented in the source code, it can be improved, as it has (at least) one limitation: if a cell is big (say 128 pixels wide) and indicated as saturated, it won't be taken into account at all. Maybe is it possible to have a smaller one, at the cost of a few pixels to lose, in which case we can center the grid using the x_start and y_start parameters.
