Claim One:
1. A method for processing a first image and a second image comprising: receiving first pixel information corresponding to the first image from a first image generator; receiving second pixel information corresponding to the second image from a second image generator; determining a first contrast value corresponding to only a portion of the first image based on the first pixel information; determining a second contrast value corresponding to only a portion of the second image based on the second pixel information; selecting one of the first and second images responsive to the first and second contrast values; generating a first tone mapping function based on the first and second contrast values for modifying contrast of the selected one of the first and second images, wherein the first and second contrast values are determined according to the following: ContrastValue = - sum ⁡ [ ( H ⁡ ( I ) sum ⁡ ( H ⁡ ( I ) ) ) * log ⁡ ( H ⁡ ( I ) sum ⁡ ( H ⁡ ( I ) ) ) ] , wherein “H” is the luminance channel histogram and “I” is the luminance channel image of the corresponding first or second image; and generating compensated image pixel information corresponding to the selected one of the first and second images by applying the first tone mapping function to the pixel information corresponding to the selected one of the first and second images.
