Camera Features
Exposure Control
Internal Exposure Control - Electronic Shutter
In global shutter mode, all pixels in the array reset at the same time, then collect signal
during the exposure time, then transfer the image to a non-photosensitive region within
each pixel. After transferring the image to the non-photosensitive region, the readout of
the array begins. In this way, all pixels capture the image during the same period, which
reduces any image artifacts due to motion within the scene. The maximum exposure is
frame-time dependent, and the minimum exposure is about 40 microseconds.
The camera normally overlaps the exposure and read-out times as shown in below.

External Exposure Control
The camera can use an external pulse to control exposure. The pulse duration determines
the exposure. In global shutter mode, the minimum exposure time is about
40 microseconds. Refer to section
