Actually, it should be called for each frame, here's algo: check that average luminance (Y_AVE) fits into stable region if not, adjust exposure to get Y_AVE into stable region. > And as long as it is only for ov9650 sensors the performance problem > doesn't concern me much. I'm still not sure that autoexposure works for OV7660 and OV7670 :) And there's no performance problem at all, 15-30 comparisons per second is nothing for todays CPUs :) > GWater Regards Vasily
