Abstract
Image saturation of a sensor pixel array is reduced by adjusting RGB color channel gains for an LED light source. Pixel saturation information is obtained from a sensor pixel array with an image on it illuminated by the LED light source. It is then analyzed to determine saturation levels of the captured image for each RGB component of the LED light source. The gain of each RGB color channel of the LED light source is then adjusted to reduce pixel saturation when using the LED light source for image capturing.
