Abstract:
1. An image enhancement system comprising: means adapted for receiving YCbCr image data encoded as a plurality of pixels in YCbCr space, wherein Y is a luma component, Cb is a blue chroma component, and Cr is a red chroma component; means adapted for selecting a maximum Y value from the image data; means adapted for receiving HSV image data corresponding to the YCbCr image data, wherein H is a hue component, S is a saturation component, and V is representative of a brightness component; means adapted for selecting a pixel from HSV image data having a minimum S value; testing means adapted for testing an S value and a V value of a selected pixel against first and second threshold levels; and adjustment means, including a processor and associated memory, adapted for selectively applying a Max-RGB algorithm to RGB image data in accordance with an output of the testing means.
