Abstract
Official abstract text for this publication.
Tone and/or gamut mapping apparatus and methods may be applied to map color values in image data for display on a particular display or other downstream device. A mapping algorithm may be selected based on location and/or color coordinates for pixel data being mapped. The apparatus and methods may be configured to map color coordinates differently depending on whether or not a pixel corresponds to a light source in an image and/or has special or reserved color values.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for mapping pixel data, the method comprising: comparing location information corresponding to the pixel data to a set of one or more special locations within an image frame, said special location being associated with a special mapping algorithm; comparing color coordinates for the pixel data to a set of one or more reserved colors, said reserved color being designated as not affected by mapping transformations; comparing color coordinates…
