Operation of the Image Sensor
Set Configuration and Pulse Timing
Figure 15.
At the start of a new frame, the device may be reconfigured. If
necessary, the output amplifier gain and offset are adjusted or
the device is put in viewfinder mode.
Then, the frame readout shift register is initiated by pulsing
"SYNC_YR". This pulse occurs once per frame, normally as a
part of the first row blanking sequence.
The readout of a row (line) starts with row blanking initialization
sequence. Here several pulses are applied for Y-direction shift,
the column amplifier S&H and nulling, and the start (SYNC_X) of
the X-direction shift register.

The frame reset shift register is started also once per frame by
"SYNC_YL", this pulse occurs once per frame, normally as a part
of the row blanking sequence of one particular row. The time
delay from the SYNC_YL to SYNC_YR is the integration time.
The integration is thus a multiple of the row readout time. The
reset shift register always leads the readout shift register.
Therefore, the integration time should be determined before the
start of the frame readout. The value that is fixed at that moment
will be the integration time of the NEXT frame. If the value set for
the integration time changes during frame readout, the start
pulse might be lost and the next frame might be invalid. We will
now discuss all steps in more detail.
