First Claim
Patent Images

1. the method that image is strengthened is characterized in that, the method that described image is strengthened comprises:

  • Capture a digital picture;

    From a plurality of pixels of described digital picture, select a specific pixel;

    Choose the contiguous a plurality of pixels of described specific pixel, to constitute a particular block;

    Calculate the mean value of described particular block;

    A plurality of curvilinear functions are provided;

    By the mean value of described particular block, described these curvilinear functions of substitution are to obtain a plurality of output brightness values;

    AndFrom described these output brightness values, find out a specific output brightness value, to find out the pairing specific curves function of described specific output brightness value near a particular luminance value.
