Claim One:
1. A system for improving the contrast of image frames, comprising: a control module configured to determine a histogram representation of an image having a plurality of pixels, each pixel having an intensity value within a range of intensity values, the histogram including the number of pixels of the image that have an intensity value for each intensity value in the range of intensity values; define a set of markers spaced across at least a portion of the range of intensity values of the histogram of the image, each marker having an associated blend factor; determine a pixel blend factor for each pixel of the image based on at least one marker blend factor; determine a first equalized pixel output value for each pixel; and calculate a final equalized pixel output value for each pixel of the image, the final equalized pixel output value for each pixel based on the pixel blend factor of that pixel, the first equalized pixel output value of that pixel, and an original pixel value of that pixel.
