Async Programmable Shutter Speed Control
In Asynchronous Programmable Shutter mode, the video signal starts with internal VINIT. When the
external VINIT pulse is applied, internal VINIT is latched to HD and the internal VINIT is delayed to
set up the shutter speed period. Video output timing starts right after the internal VINIT and single
shots, FDV is output at the internal VINIT timing. Shutter speed is determined by a direct shutter
value entered from 1 to 1040 via the camera’s control software. The shutter value equals 1.5H
(horizontal line time) or 47.6
μ
sec for each increment.
