The MER-G-P/MER-G series camera supports Auto Exposure feature. If the Auto Exposure feature is
enabled, the camera can adjust the exposure time automatically according to the environment brightness.
See section 8.3.4 for details.
The stepped exposure correspondence of MER-203-30GC-P-L, MER-203-30GC-P-L-F03 and MER-204-
30GC-P-L-F02 is as follows:

Overlap Exposure and Non-overlap Exposure
There are two stages in image acquisition of the MER-G-P/MER-G series camera: exposure and readout.
Once the camera is triggered, it begins to integrate and when the integration is over, the image data will
be read out immediately.
