===== Rolling shutter =====
 +
For a rolling shutter sensor, such as IMX178, a complete image frame requires two image cycles to complete the process from exposure to output. So the maximum frame rate is half of the video streaming mode.
 +
 +
In normal trigger mode, for rolling shutter sensor, we refer to two consecutive frame cycles as one '''''trigger cycle'''''.
 +
 +
In normal trigger mode, if multiple frames are triggered at one time, the trigger delay acts after this trigger signal, and the trigger interval and exposure delay are valid before each '''''trigger cycle'''''.

==== High-speed continuous trigger mode ====

 +
===== Rolling shutter =====
 +
In high-speed trigger mode, set '''Trigger Number''' to N, frames 2-N are output immediately after the previous frame and there is no more trigger interval. This allows the same maximum frame rate to be achieved as in video streaming mode.
