Chrominance subsampling options. When pixels are converted from RGB to YCbCr (see #TJCS_YCbCr) or from CMYK to YCCK (see #TJCS_YCCK) as part of the JPEG compression process, some of the Cb and Cr (chrominance) components can be discarded or averaged together to produce a smaller image with little perceptible loss of image clarity. (The human eye is more sensitive to small changes in brightness than to small changes in color.) This is called “chrominance subsampling”.
