Camera Readout and Coordinates
The camera readout begins with pixel 1 and reads out successive pixels from left to right
until the entire row is completed. This process is repeated with each successive row in the
frame. Pixel coordinates are expressed as column and rows, where the first pixel's
coordinates are 1, 1 and the last pixel's coordinates are 2352, 1728.
