Patent ID: 8126063

Claim:
A method of detecting a still object in digital video data, the method comprising: providing video data comprising a sequence of frames; selecting a plurality of consecutive frames from the sequence of frames; selecting a group of pixels from each of the plurality of consecutive frames, the selected groups of pixels being at corresponding positions in the plurality of consecutive frames, the video data comprising pixel data for each of the pixels; performing normalized cross correlation (NCC) on the pixel data of two of the selected groups of pixels, thereby generating an NCC value; and determining whether the NCC value is within a predetermined range indicative of there being at least a portion of the still object in the groups of pixels; determining whether the pixel data of at least one of the selected groups contains data for displaying a moving and repeating object on a device; and performing a logic operation on the results of the range determining and the moving and repeating object determining, thereby generating an output indicative of there being at least the portion of the still object in the groups of pixels.
