4 Timing and read out of the image sensor
The timing of the LUPA-4000 sensor consists of 2 parts. The first part is related with
the control of the pixels, the integration time and the signal level. The second part is
related with the readout of the image sensor. As this image sensor is able for full
synchronous shutter, integration time and readout can be in parallel or sequential.
In the parallel mode the integration time of the frame I is ongoing during readout of
frame I-1. Figure 11 shows this parallel timing structure.

The control of the readout of the frame and of the integration time are independent of
each other with the only exception that the end of the integration time from frame I+1
is the beginning of the readout of frame I+1.
The LUPA-4000 sensor also can be used in sequential mode (triggered snapshot
mode) where readout and integration will be sequentially. Figure 12 shows this
sequential timing sequence.
