Figure 11-39 Programmable timing output referenced with Hsync (Top: top to center / Bottom: center to bottom)
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.
11-5 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.
Correction Level
for white spots
Exposure time
Ratio of the number of pixels to be
corrected to the number of all pixels
High
In case of 1 second or longer exposure time
Approximately 0.1 %
Medium (Default)
In case of 1 second or shorter exposure time
Approximately 0.05 %
Low
In case of 10 ms (default) or shorter exposure time
Less than 0.001 %
