CDS c ircuit reduces noise signals generated from various sources ma inly res ulting from process variations. ixel output is compared with the reset level of its own and only the difference signal is sampled, thus reducing fixed error signal level. Each of R, G, B pixel output can be multiplied by different gain factors to balance the color of images in various light conditions. The analog signals are converted to digital for ms one line at a time and 1 line data are streamed out column by column. The Bayer RGB data are passed through a sequence of image signal proces sing blocks to finally produce YCbCr 4:2:2 output data. mage s ignal processing includes such operations as gamma correction, defect correction, low pass filter, co lor interpolation, edge enhancement, color correction, contrast stretch, color s aturation, white XELLUS C,.
