Figure 10-15 (Example for Programmable timing output with Hsync in Lightsheet Readout Mode, forward
direction readout)
When you choose Hsync for the reference of programmable timing output, camera can output
some pulses before start the exposure. It is called as Pre-Hsync. You can set the number of
Pre-Hsync.
(3) Trigger ready output
The trigger ready output is useful to make the frame intervals as short as possible in external
trigger mode. For example, when the camera is working in the Edge trigger mode, the next frame
can start after the previous frame exposure is done. Thus, the camera cannot accept a trigger for
the next frame during the exposure period. To reduce useless time to be as short as possible, it
is necessary to know the period when the camera can accept a trigger for the next frame. The
trigger ready output shows the trigger ready period when the camera can accept an external
trigger in External trigger mode.
10-8 REAL-TIME DEFECT PIXEL CORRECTION
There are a few pixels in CMOS image sensor that have slightly higher readout noise performance
compared to surrounding pixels. And the extended exposures may cause a few white spots which is
caused by failure in part of the silicon wafer in CMOS image sensor. The camera has real-time variant
pixel correction features to improve image quality.
The correction is performed in real-time without sacrificing the readout speed at all. This function can
be turned ON and OFF. (Default is ON)
User can choose the correction level for white spots depend on the exposure time.
