System for and method of detecting strobe using spatial features in video frames

摘要

A video processing device includes a histogram generating component, an analyzing component, a comparator and an encoding component. The histogram generating component can generate a histogram for image data of an image frame. The analyzing component can analyze the histogram, can identify an isolated spike in the histogram and can output at least one strobe parameter. The comparator can compare the at least one strobe parameter with at least one predetermined threshold, can output a first instruction signal when the at least one comparison operation is indicative of a strobe and can output a second instruction signal when the at least one comparison operation is not indicative of a strobe. The encoding component can encode the image data in a first manner based on the first instruction signal and can encode the image data in a second manner based on the second instruction signal.

1. A video processing method comprising:
generating, via a histogram generating component, a histogram for image data of an image frame; analyzing, via an analyzing component, the histogram; identifying, via the analyzing component, an isolated spike in the histogram; and outputting, via the analyzing component, at least one strobe parameter indicating the possibility of a strobe within the image frame; wherein said identifying the isolated spike comprises identifying the isolated spike by establishing a region threshold that partitions the histogram into a first region and a second region, and by establishing sub-region thresholds that partition the second region into a first sub-region and a second sub-region.
