• H-center: Set the horizontal center location. The values range from 0 to
255.
• V-center: Set the vertical center location. The values range from 0 to

Defect: If the camera’s image sensor displays some defective pixels, this could
be due to them responding to light exposure differently compared to the
surrounding pixels. Use the Defective Pixel Correction (DPC) function to enable
the camera to digitally correct defective pixels using its image signal processor.
• Sensup: Adjust the magnification of existing light sources to make it
easier for the camera to detect defective pixels. If set too strong, the
camera can regular noise mistakely as defective pixels. The values
range from x4 to x128.
• Diff: Set a value to increase the difference between surrounding pixels
to find a dead pixel. The larger the value, the larger the size of the dead
pixel found. The values range from 0 to 3.
• Threshold: Set threshold value. The values range from 0 to 4.
• Start: Perform STATIC DPC. The camera closes the lens automatically
and detects defective pixels that exceed the specified level. You need to
cover the lens with your hand during the test.
