Abstract:
1. A method of adjusting a value for a pixel of an image, comprising: inputting an image pixel value associated with the pixel; determining a location in a pixel array of the pixel; determining a vertical portion and a horizontal portion of a correction value for the image pixel value using a plurality of vertical correction value curves and a plurality of horizontal correction value curves, respectively; and correcting the image pixel value by determining a correction value for the image pixel value and applying the correction value to the image pixel value; the correction value being a function of the vertical correction value portion and the horizontal correction value portion wherein each of the plurality of vertical correction value curves that represents the vertical portion of the correction values corresponds to pixels in an entire column of the pixel array and each of the plurality of horizontal correction value curves that represents the horizontal portion of the correction values corresponds to pixels in an entire row of the pixel array.
