Positional Gain Adjustments (PGA)

Lenses tend to produce images whose brightness is significantly attenuated near the

edges. There are also other factors causing fixed pattern signal gradients in images

captured by image sensors. The cumulative result of all these factors is known as image

shading. The AP0100CS has an embedded shading correction module that can be

programmed to counter the shading effects on each individual R, Gb, Gr, and B color

signal.

The Correction Function

The correction functions can then be applied to each pixel value to equalize the

response across the image as follows:

(EQ 1)

where P are the pixel values and f is the color dependent correction functions for each

color channel.
