6.2 Rolling Shutter

For cameras that support rolling shutter: as soon as the exposure ends, and the data readout starts
simultaneously. After the whole action, the rest of rows start to expose and read out one by one.
All pixels expose at the same time, then readout at different time, as shown below.

The figures of rolling shutter's signal readout under internal trigger mode and external trigger
mode are the same with those of global shutter as shown above.

6.3 Non-Overlap Exposure and Overlap Exposure

The process that camera captures one frame of image includes two stages, exposure and readout.
According to the overlap relation between the exposure time and the readout time, cameras with
different sensors can be divided into overlap exposure and non-overlap exposure.
