Abstract
An image processing device and method are provided for adjusting background pixels of an image. The device includes memory which stores a background adjustment component which for each of a plurality of pixels of an input image: computes a background strength of the pixel; computes a luminance strength of the pixel; and computes adjusted luminance and adjusted chrominance values for the pixel, as a function of the background strength and luminance strength of the pixel. An image output component outputs an output image derived from the adjusted luminance and adjusted chrominance values for the plurality of pixels, A processor implements the background adjustment component and image output component.
