Claim One:
1. A computer-implemented method of correcting for backlighting in images on a display device, the method comprising: receiving, at a processor, image data corresponding to at least one image captured by a camera; detecting, by the processor, a region of interest within the image; determining, by the processor, a position and size of the region of interest within the image; determining, by the processor, luma values within the region of interest; determining, by the processor, whether to brighten the region of interest, based at least in part on the determined luma values, comparing the determined luma values to preset luma values, and comparing the captured image to a plurality of previously captured images; revising, by the processor, upon such determination, at least some of the luma values of the received image data to brighten the region of interest, wherein revising comprises temporal smoothing of the brightening with regard to feedback associated with adjustments made to the previously captured images; blending, by the processor, the brightened region of interest with the remainder of the image to produce a modified image, wherein blending comprises spatially smoothing the brightening from a central zone of the region of interest through a transition zone, using a raised cosine function having a continuous derivative; and displaying, under control of the processor, the modified image on a display device.
