3.4H Reset Mode

Normally, video noise appears when the beginning of trigger signal is applied before finishing the video readout of the previous frame. This noise is caused by the SUB pulse, which is activated to clear all residual charges on the CCD prior to a new exposure. By selecting this “H. Reset Mode”, the camera automatically holds the actual activation of trigger until the next horizontal blanking period. By doing this, the SUB pulse is activated during the horizontal blanking period and the noise in image can be avoided.

Note: Due to the principal of this operation, there can be maximum “1 H” of delay of actual trigger signal.
