Patent ID: 8781238

Claim:
A method to combine decoding and post-processing of a coded HDR image with a processor, the method comprising: accessing the coded HDR (high dynamic range) image, the HDR image comprising a JPEG-coded baseline image and a second coded image, wherein the JPEG-coded baseline image comprises a plurality of 8×8 coded baseline image blocks and the second coded image comprises a plurality of coded regions; partially decoding the JPEG-coded baseline image according to a post-processing command for the HDR image to output a first decoded image, wherein the partial decoding of the first coded image comprises: performing an N×N IDCT (Inverse Discrete Cosine Transform) on each one of the plurality of the coded 8×8 baseline blocks, where N is a positive integer smaller than 8 but larger or equal to 1; partially decoding the second coded image according to the post-processing command to output a second decoded image; and combining the first decoded image and the second decoded image to output a decoded and post-processed HDR image.
