6.3.2 ROLLING SHUTTER
In Rolling Shutter mode the pixel reset and exposure start is carried
out row by row. Each row has the same exposure time, but a different
start and end of exposure. The pco.edge image sensor consists of
two discrete halves, which are exposed and read out simultaneously,
i.e. from the outside to the center by default. Within one row, the
exposure starts simultaneously for all pixels.
General Timing Diagram
The exposure time of each row starts with the corresponding reset of
the row. Then after a predefined time, the exposure is stopped. The
light induced accumulated charge carriers of the pixels in a row are
recorded into memory in a low noise (readout) mode. This results in
the total image appearing in memory corresponding to the row
readout.
