摘要:
An image processor is provided for correcting brightness of saturated pixels of a captured image. The image processor can include a pixel saturation determiner that whether one or more pixels in an image sensor have been saturated by comparing pixel brightness levels of the pixels to a predetermined saturation threshold. Moreover, the image processor includes an image enhancer that generates a corrected image without artifacts due to the saturated pixel(s) by replacing the pixel brightness of the saturated pixel(s) with a pixel correction value that is based on a pixel brightness of one or more unsaturated pixel in the image sensor.
