Patent Images

1. A method of processing image data of a scanned object, the method comprising:

  • performing, in integer format, a pixel offset correction on the image data using unsigned saturation arithmetic to produce an image in integer format having negative value pixels clipped to a value of zero;

    converting the resulting pixels to floating point format and multiplying the converted pixels by a positive floating point gain factor;

    converting the resulting pixels to integer format and clamping the converted pixel values to a maximum value using saturation arithmetic;

    performing, in integer format, non-functional pixel correction and clamping the resulting pixel values to a maximum value using saturation arithmetic; and

    mapping in integer format the resulting pixel value to a palette index using a lookup table to establish an output pixel intensity having one of a plurality of intensity levels.
