There are also tolerances in lens which could lead to optical offsets.
1.10 Sensor Overview
By default, the steps exposure and readout out of an image sensor are done one after the other. By design, CCD
sensors support overlap capabilities also combined with trigger (see figure). In contrast, so-called pipelined CMOS
sensors only support the overlapped mode. Even less CMOS sensors support the overlapped mode combined with
trigger. Please check the sensor summary (p. 61). In overlapping mode, the exposure starts the exposure time
earlier during readout.

The CCD sensors are highly programmable imager modules which incorporate the following features:
