Method and Apparatus for Enhancing the Dynamic Range of an Image |
摘要 |
A method of converting an image signal from an original dynamic range to a target dynamic range includes dividing the original dynamic range and the target dynamic range in to a plurality of corresponding sub-ranges and mapping each original sub-range to its corresponding target sub-range. One of the dynamic ranges is divided into a plurality of sub-ranges having equal size and the other dynamic range is divided into the corresponding sub-ranges each having a size based on a characteristic of the corresponding equal size sub-ranges. The invention may be employed in display, capture and image processing apparatus.
