Figure 167: Choosing the network interface

22.10  OpenGL® ES

OpenGL® ES is a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded
systems. See the Khronos website for more details.

22.11  Overlapped / pipelined transfer

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.

In overlapping mode, the exposure starts the exposure time earlier during readout.
