Strategies processing image information using the color information data structure

摘要

PROBLEM TO BE SOLVED: To explain a strategy to process image information.SOLUTION: Color information describes color-related formatting applied to the image information. A data structure can be passed down a video processing pipeline, where each component in the pipeline can draw color information from the data structure to improve the accuracy of its processing. Each component can supply previously unknown color information to the data structure for use by other components in the pipeline. Exemplary fields of the data structure can include one or more of: a video transfer function field; a color primaries field; an image light field; a transfer matrix field; a nominal range field; and a video chroma sampling field. The transfer matrix field is used to convert image information from one color space to another. Processing operations can be performed on progressive and linear RGB image information.
