3 × 3 Filter
Monochrome cameras and color cameras perform 3 × 3
area filtering on RAW output. The brightness of a central
pixel and the eight pixels around it, and the parameter of
each pixel are multiplied and added together, The result
is the brightness of the center pixel. Specify using values
between –8191 and +8191. The parameter 256 is ×1.
Depending on the patterns of coefficients, you can use
filtering to reduce noise, enhance edges, and extract
contours.
