The camera sub system for the OMAP 3 processors does allow for raw and a few other things. The link below is to TI's omap35x camera subsystem manual. I would assume that the two camera subsystems would be very similar if not the same. http://focus.ti.com/lit/ug/sprufa2b/sprufa2b.pdf This manual suggests the following features are in hardware: - custom white balance - Colour filter - noise reduction - Programmable color correction (RGB to RGB) - Programmable gamma correction: 1024 entries for each color - Programmable color conversion (RGB to YCbCr 4:4:4) -Color subsampling (YCbCr 4:4:4 to YCbCr 4:2:2) - Luminance enhancement (non-linear) - Resizing These features should be accessible from camera drivers as I would assume they are the same drivers that are used for the OMAP35x processors. Other features could be implemented in software.
