ipa: rpi: Gate CamHelper::prepare() by the mistrust count The current logic in the IPA gates the controller/algorithms from running on a the frame if mistrustCount_ > 0. This logic is somewhat incorrect, as the image data is indeed valid, just the embedded data and other bits of metadata are possibly invalid. This com…

libcamera: software_isp: Normalize statistics sums to 8-bit The SWSTATS_ACCUMULATE_LINE_STATS() macro divides the luminance value for the histogram to normalize it to 8-bit range, but does not apply the same normalization to the RGB sums. For 10-bit and 12-bit unpacked Bayer formats this means the sums are accumulated…
