(3) Level trigger mode
The Level trigger mode is used to control both exposure start timing and exposure time length by
inputting external trigger pulses. In this mode, the camera starts exposure at the start of high or
low period of the input trigger pulse and stops exposure at the end of high or low period of the
input trigger pulse.
The example below is for the trigger level High. The exposure of the first four lines (0H - 3H)
begins when the trigger signal becomes High, and the exposure of the second four lines (4H -
7H) begins after the readout time of line one passes. Each exposure begins one by one for each
four lines. The exposure of the first lines is finished when the trigger signal becomes low, and
signal readout is begun. The exposure time of each four lines is defined by the time that the input
trigger is high.
