CV-A10 CL and CV-A70 CL
6.4.7. Sensor Gate Control
This mode is for applications with strobe flash illuminations or long time accumulations up to
several frames. In this mode the camera is running continuously. The external Sensor Gate
control signal will disable the internal XSG pulse so the accumulation will continue during the
next frame. The resulting video is read out after the first FVAL (or SG), following the trailing
edge of the Sensor Gate Control signal.
To inhibit the internal XSG pulse and continue the accumulation, the external sensor gate
control signal should be low during line 28, where the internal XSG is placed. Fig. 32.
The sensor gate control signal can be synchronized by the FVAL signal. Fig. 31. and fig. 32.
For video out timing details, refer to fig. 13. - 14.
