  • Publication number: 20080211945
    Abstract: An image sensor includes a first sub-pixel, a second sub-pixel, and an image processor. The first sub-pixel generates a first image signal with a first sensitivity, and the second sub-pixel generates a second image signal with a second sensitivity less than the first sensitivity. The image signal processor adds a change in the second image signal from a saturation level to the first image signal to generate a final image signal when the first sub-pixel is saturated.
