ENCODING HIGH DYNAMIC RANGE VIDEO DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 17933744 titled 'ENCODING HIGH DYNAMIC RANGE VIDEO DATA

Simplified Explanation

The example device for encoding high dynamic range (HDR) video data includes a memory to store video data and processors to calculate a histogram for an image of the video data, encode values for the histogram in linear light format, and encode the image itself. The histogram data is stored in an array of variables with a size of 2x18 bits, and codewords representing values for bins of the histogram are selected from a set of codewords for a PQ10 format for HDR images. The bins of the histogram represent non-equal width ranges.

Original Abstract Submitted

An example device for encoding high dynamic range (HDR) video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: calculate a histogram for an image of the video data, the image being expressed in a linear light format; encode values for the histogram of the image expressed in the linear light format; and encode the image. Data for the histogram may be expressed in an array of variables having a size of 2×18 bits. The device may encode codewords representing values for bins of the histogram, where the codewords may be selected from a set of codewords for a PQ10 format for HDR images. The bins of the histogram may represent non-equal width ranges.
