8.6. Blemish compensation
The SP-5000M-CXP2 and SP-5000C-CXP2 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-CXP2, the defective pixels can be compensated by the same Bayer color pixels in both
adjacent columns. The number of pixels that can be compensated is up to 512 pixels.
Fig. 35 Blemish compensation
If several consecutive pixels are defective in the horizontal direction, 3 pixels for
monochrome and 2 same color pixels for color can be compensated.
