Abstract
Systems and methods for performing color mapping operations. One system includes a processor to perform post-production editing of image data. The processor is configured to identify a first region of an image and identify a second region of the image. The first region includes a first white point having a first tone, and the second region includes a second white point having a second tone. The processor is further configured to determine a color mapping function based on the first tone, apply the color mapping function to the second region of the image, and generate an output image.
Claims15
A video delivery system for context-dependent color mapping, the video delivery system comprising:
- a processor to perform post-production editing of video data including a plurality of image frames, the processor configured to:
- identify a first region of one of the image frames, the first region including a first white point having a first tone;
- identify a second region of the one of the image frames, the second region including a second white point having a second tone;
- determine a color mapping function based on the first tone and the second tone;
- apply the color mapping function to the second region;
- and
- generate an output image for each of the plurality of image frames.
A method of context-dependent color mapping, the method comprising:
- with a processor, editing video data including a plurality of image frames by:
- identifying a first region of one of the image frames, the first region including a first white point having a first tone;
- identifying a second region of the one of the image frames, the second region including a second white point having a second tone;
- determining a color mapping function based on the first tone and the second tone;
- applying the color mapping function to the second region;
- and
- generating an output image for each of the plurality of image frames.
