The Blue circle indicate the maximum 1288 X 1028 active pixels, Red circle the window of interest, and Pink
circle the Virtual Frame. Virtual Frame represents the frame time and the size of it indicates that the frame
time is the time to readout all the pixels in this Virtual Frame.
The readout row and column is programmed by WOI(wcp, wrp, wcw, wrd), Sub-sampling(cf, rf) and readout
direction(rrc, rrr). The readout rows and columns are shown in the following figures.
