(1) Edge trigger mode
The Edge trigger mode is used so that the exposure starts according to an external signal.
Exposure time is set. In this mode, the exposure of the first line begins on the edge (rising /
falling) timing of the input trigger signal into the camera. (1023H and 1024H in the following
figure) The exposure of the second line is begun after the readout time of one line passes (1022H
and 1025H in the following figure), and the exposure is begun one by one for each line.
