FUNCTIONS

Internal operations of camera in trigger shutter operation mode

An about 3 ∝s width SUB pulse is generated immediately after trigger is input. Signals accumulated in the CCD sensor until then are eliminated, after which exposure is started. After the exposure time based on the shutter speed set passes, VD is generated inside the camera. (Specifically, VD is generated about 10 ∝s before exposure ends.)

After the A period passes from the falling edge of the VD, images are output during the B period.
