After the digital clamping is applied to the data, black level compensation is applied (see Figure 12-1191). In this operation, a fixed value is subtracted from the data depending on the color (that is R/Ye, Gr/Cy, Gb/G, and B/Mg). The offset (VPFE_BLKCMP register) that is applied to each data sample is selected according to the 0/1/2/3 phase and the color (0/1/2/3) specified for each phase (VPFE_COLPTN). The color pattern definition is very flexible in order to accommodate many different capture devices, including normal Bayer CFA sampling, Foveon sensors, and VGA movie mode CCDs, whose VGA draft mode output does not follow the typical Bayer pattern.
