Note: Under the following conditions, the shading correction circuit may not work properly.
If there is some area in the image with a video level less than 70%
If part of the image or the entire image is saturated
If the highest video level in the image is less than 300LSB (at 10-bit output)
8.6. Blemish compensation
The SP-5000M-GE2 and SP-5000C-GE2 have a blemish compensation circuit. This function
compensates blemishes on the CMOS sensor (typically pixels with extremely high response or
extremely low response). This applies to both monochrome and color versions. Pixels that fulfill the
blemish criteria can be compensated by adjacent pixels in both columns and, in the case of the
SP-5000C-GE2, the defective pixels can be compensated by the same Bayer color pixels in both
adjacent columns. Please refer to the following drawing. As for white blemishes, the automatic
detection function is available and after its execution, the data is stored in memory. The customer
can use the data by setting the blemish compensation ON. For black blemishes, only compensation
that has been done in the factory is available. The number of pixels that can be compensated is up
to 512 pixels.

Note: If defective pixels are found consecutively in the horizontal direction, the blemish
compensation circuit does not work.
8.7. Bayer color interpolation (Only for SP-5000C-GE2)
This function is available only for SP-5000C-GE2. The SP-5000C-GE2 uses a CMOS sensor with an RGB
Bayer pattern. If the in-camera Bayer color interpolation is not used, the following RAW data can be
output.
