The first part is related to the control of the pixels, the
integration time, and the signal level. The second part is
related to the readout of the image sensor. As full
synchronous shutter is possible with this image sensor,
integration time and readout can be in parallel or sequential.

end of the integration time from frame I+1 is the beginning
