3.3 Edge Preset Trigger Mode

In this “edge preset trigger mode”, the camera exposure starts at the rising edge of the trigger signal like the

“pulse width trigger mode” in the previous sections. However, in this mode, the exposure duration time is based on the

preset value stored by the by the camera setting communication.

Note 1: The camera does NOT switch to the normal mode when the long exposure mode is selected.

Note 2: The internal VD signal is reset immediately after the exposure is finished as depicted and the video output

signal is sent out according to the reset VD timing.

Note 3: The exposure time is preset by the camera setting communication as “shutter speed”.
