BlemishCompensation

Related Setting Items:
Multiple defective pixels that are not adjacent to each other can occur on CMOS sensor cameras.
This camera features a function that interpolates defective pixels using the surrounding pixels. Up to
2000 pixels can be corrected. Pixel interpolation can be performed via automatic detection or point-by-
point manual settings.

Automatic Detection

Automatic detection can only detect lit defective pixels (i.e., white blemishes).
1. Shield the camera sensor. If a lens is attached, use the lens cap as a shield, for example.
2. Configure the threshold level for defective pixel detection with BlemishDetectThreshold.
Up to 2000 pixels can be corrected.
l
The threshold value is specified as a percentage.
l
The default setting is "10" with 10% of the full scale (100%) specified as the threshold
l
value.
3. Execute BlemishDetect to start automatic detection. After detection, the interpolation data is
saved to the camera's internal memory.
To check the number of interpolated pixels after automatic detection
You can check the number of pixels interpolated via automatic detection by loading the BlemishNum
data.
