Defective Pixel Replacement Algorithm Description
The replacement algorithm follows a few basic rules as defined below, which in general provides
satisfactory results.
Monochrome Cameras
• If the bad pixel is the first of a line, it is replaced by the next whether good or not.
• If the bad pixel is not the first of a line, it is replaced by the previous pixel.

Color Cameras
The replacement algorithm rules for Bayer a color sensor is similar to the monochrome rules with
the exception that replacement pixels of the same color as the bad are used. The two replacement
cases below describe general color pixel replacements.
• If the bad pixel is the first of a line, it is replaced by the next of the same color, whether
good or not.
• If the bad pixel is not the first of a line, it is replaced by the previous pixel of the same
color.
