  • Adaptive dithering during image processing
    Patent number: 8681880
    Abstract: Systems and method are provided for adjusting certain pixel values in an image. In an embodiment of the invention, an average pixel value of pixels at given distances from a selected pixel are examined to determine if the pixel is in a high-contrast area. If the pixel is in a smooth color gradient transition area, the pixel value may be adjusted in some embodiments using an additional dither or dither pattern to reduce differences between the pixel values of the selected pixel and the additional average pixel values exceeding the lower threshold.
