6.3.4 GLOBAL RESET
All pixels are globally reset and the exposure starts for all rows at the
same time. The exposure stop is carried out row by row; therefore the
duration of the exposure is not the same for all pixels. The rolling
readout improves the image quality, but due to the difference in
exposure time, a flash illumination is recommended. The readout
(exposure stop) is done from the outside to the center.
General Timing Diagram
The exposure time of all rows starts simultaneously. The exposure
time of the first row stops after the predefined time, the following
rows are read out from the outside to the center row by row. Please
note that this leads to a different duration of exposure time for all
rows.
Timing
The exposure and delay time can be adjusted in steps of one line
time (see 1.2).
