may vary from frame to frame. See Figure 31.
sums all 361 pixels in the current frame. It may be described as the full sum divided by 128. The formula to
calculate the average pixel value is as below:
Average Pixel = Register Value x 128/361
The maximum register value is 178 (63 x 361 / 128 truncated to an integer). The minimum is 0. The pixel sum
value may vary from frame to frame.
