SYSTEM AND METHOD FOR ADAPTIVE CONTRAST ENHANCEMENT OF VIDEO SIGNALS |
| 摘要 |
<p>A method for contrast enhancement of a video signal comprises receiving a video signal frame, gathering statistics about the video signal frame, calculating the effective input dynamic range of the video signal frame, calculating the effective output dynamic range of the video signal frame, and constructing a transform to enhance the picture in the video signal frame by mapping the effective input dynamic range to the effective output dynamic range via the transform.</p> |
