  • System with a random number generator used to remove contouring in CMOS imager data having an extended dynamic range
    Patent number: 7349126
    Abstract: The present invention is a method of image data processing that includes determining whether the image data indicates photodiode saturation, and removing contouring from the image data caused by the saturation. The contour artifact removal is accomplished by adding a random number to adjusted photodiode data from an extended range imager when the data from the imager indicates that the photodiode has been saturated. The adjusted photodiode data is a sum of photodiode data and spillover rate adjusted diffusion data.
