Apparatus and method for reducing distortion in images

摘要

A system that incorporates teachings of the present disclosure may include, for example, a set-top box having a processor operable to receive video content from a multimedia source, to detect at least one frame in the video content affected by a high intensity burst of light, and to determine a chrominance reference from frames in the video content unaffected by the high intensity burst of light. The processor is also operable to modify chrominance in the at least one frame according to the chrominance reference without altering spatial characteristics of objects in the at least one frame, to replace the at least one frame in the video content with the modified at least one frame to create updated video content, and to present the updated video content at a presentation device. Other embodiments are disclosed.

主权项

1. A set-top box, comprising:
a memory to store instructions; and a processor coupled to the memory, wherein responsive to executing the instructions, the processor performs operations comprising: receiving video content from a multimedia source; detecting a frame in the video content affected by a high intensity burst of light, wherein the affected frame has a luminance greater than a reference luminance; determining a chrominance reference comprising a collection of respective measurements of chrominance of a plurality of objects in frames in the video content unaffected by the high intensity burst of light, wherein the unaffected frames each have a luminance less than the reference luminance; modifying chrominance of objects in the affected frame according to the chrominance reference without altering spatial characteristics of the objects in the affected frame to produce a modified frame; replacing the affected frame with the modified frame to create updated video content; and presenting the updated video content at a presentation device.
