BlemishCompensation
Related Setting Items:
Multiple defective pixels that are not adjacent to each other can occur on conventional CMOS sensor
cameras.
This camera features a function that interpolates defective pixels using the surrounding pixels. Up to
200 pixels can be corrected for each of the three sensors. 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.
Up to 200 pixels can be corrected for each of the three sensors.
The threshold value is specified as a percentage. The default setting is "10" with 10% of the full scale
(100%) specified as the threshold value.
3. Execute
Blemish Detect
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.
