Abstract:
A computer-implemented method for processing an uncompressed video stream, comprising the steps of:(a) detecting a flash sequence in the uncompressed video stream, wherein the flash sequence is a set of one or more consecutive pictures in which: (1) a picture preceding the flash sequence is poorly correlated to the flash sequence; (2) a picture following the flash sequence is poorly correlated to the flash sequence; and (3) the picture preceding the flash sequence is well-correlated to the picture following the flash sequence, wherein step (a) comprises the step of determining that the picture preceding the flash sequence is well-correlated to the picture following the flash sequence; and (b) adjusting video compression processing based on the detection of the flash sequence to generate part of a compressed video bitstream corresponding to the uncompressed video stream.
