Figure 31-3 Statistic Blocks Example For 288 X 216 Pixels Image Size; Table 31-11 Block Size For Live View Lcd Size - Motorola DragonBall MC9328MX1 Reference Manual

CMOS Sensor Interface Module
Because there are twice as many green pixels as red or blue pixels, the value generated for the green is
calculated by skipping every other line to produce results that are of the same magnitude as the blue and
red pixels.
