METHODS, SYSTEMS AND APPARATUS FOR OVER-EXPOSURE CORRECTION

摘要

An aspect of present principles is directed to methods, apparatus, systems and computer readable media for image processing. The image processing may include receiving a standard dynamic range (SDR) image or a receiver for receiving a standard dynamic range (SDR) image. It may further include determining an over-exposed region of the SDR image and determining a corrected luminance value for at least a pixel of the over-exposed region, or a processor configured to determine an over-exposed region of the SDR image and a corrected luminance value for at least a pixel of the over-exposed region. The corrected luminance value is determined based on at least one of a shape of the over-exposed region, luminance information of pixels surrounding the over-exposed region, and edge information of the pixels surrounding the over-exposed region. The over-exposed region may be an irregularly shaped region.

1. An image processing method comprising:
determining a corrected luminance value for at least a pixel of an over-exposed region determined from a standard dynamic range (SDR) image; wherein the corrected luminance value is determined based on at least one of a shape of the over-exposed region, and edge information of the pixels surrounding the over-exposed region.
