Abstract
A method and apparatus for enhancing the contrast and visual clarity of an image captured by a remote viewing device. A luminance component of a captured image is isolated and represented within a first distribution of luminance values. One or more transformation functions are performed upon the first distribution of luminance values to generate a second distribution of luminance values. The second distribution of luminance values are used to construct and display a second image having enhanced visual clarity relative to the captured image. A portion of the captured image, such as a portion functioning as a magnified zoom window, can be enhanced for visual clarity independently from the remaining portion of the captured image.
