Abstract:
1. A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause a set of steps to be carried out for identifying a black/non-black attribute of a current frame, said set comprising: receiving the current frame; defining a region of the current frame, the region having a plurality of lumas within a luma range; calculating a non-black luma percentage of said region based on said lumas; calculating a white luma percentage of said region based on said lumas; calculating an average luma of said region based on said lumas; identifying the current frame as having a black attribute responsive to three conditions being satisfied, the first of the three conditions being that said average luma is less than a max-black luma threshold, the second of the three conditions being that said non-black luma percentage is less than a non-black luma percentage threshold, and the third of the three conditions being that said white luma percentage is less than a white luma percentage threshold; and storing an indication of an associated black/non-black frame attribute in a memory.
