Techniques for high dynamic range image processing are presented. Base layer data, first checksum parameter, and residual ratio data for a high dynamic range (HDR) image are each received. A second checksum parameter is computed for the base layer data based upon the first SOF after the last APP 11 marker segment and includes all following bytes up to and including the EOI marker. The first and second checksum parameters are compared to determine if base layer has been altered. |
