Patent ID: 8761502

Claim:
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 colorbar/non-colorbar attribute of a current frame, said set of steps comprising: receiving the current frame; defining a region of the current frame, the defined region having a plurality of lumas within a luma range; for each luma in said luma range, calculating a luma percentage of said region; calculating a significant luma percentage counter based on said luma percentages and a qualifying luma percentage threshold; calculating a significant luma percentage of said region, based on said luma percentages and said qualifying luma percentage threshold; determining a max-luma of said region based on said lumas; and identifying the current frame as having a colorbar attribute responsive to every condition in a condition set being satisfied, the condition set comprising at least first, second, and third conditions, said first condition being that said significant luma percentage counter is within a significant luma percentage counter range, said second condition being that said significant luma percentage is greater than a significant luma percentage threshold, and said third condition being that said max-luma is greater than a fade luma threshold; and storing an indication of an associated color-bar/non-colorbar frame attribute in a memory.
