Title:
METHOD AND APPARATUS FOR SELECTIVELY ENHANCING AN IMAGE
Document Type and Number:
WIPO Patent Application WO/2014/033732
Kind Code:
A3
Abstract:
The present invention provides a method and apparatus for selectively enhancing regions in an image. In one embodiment, a digital image is read from an image source and is converted into a desired image model. One or more regions in the image having intensity values of pixels falling outside a pre-determined optimal intensity range are determined. The one or more regions in the image are then enhanced using a modeled light source of an optimal intensity such that the intensity value of pixels corresponding to the one or more regions in the image fall within the pre-determined optimal intensity range.
