Patent ID: 8059911

Claim:
A device for performing one or more of depth-based image enhancement and depth-based video enhancement, the device comprising: a depth estimation unit that generates three-dimensional (3D) depth information from a two-dimensional (2D) image; an image enhancement unit that enhances the 2D image according to the 3D depth information, wherein the image enhancement unit comprises one or more of the following elements: a depth-based edge enhancement unit that emphasizes edge details of the 2D image; a color space converter that converts the 2D image between color spaces to obtain a luma component and a chroma component of the 2D image; a depth-based contrast adjustment unit that enhances contrast characteristics of the luma component; a depth-based saturation adjustment unit that enhances saturation characteristics of the chroma component; and a color space back-converter that converts the adjusted luma and chroma components back to a color space of the original 2D image, wherein the color space converter converts the 2D image from red/green/blue (RGB) color space to hue/saturation/intensity (HSI) color space, and wherein the color space back-converter converts the enhanced 2D image from the HSI color space back to the RGB color space.
