VIDEO SIGNAL PROCESSING APPARATUS, VIDEO SIGNAL PROCESSING METHOD, AND PROGRAM

摘要

A video signal processing apparatus including: a video signal band measurement unit that measures a signal band of an input video signal; a band level evaluation unit that evaluates a band level of the resultant signal band measured by the video signal band measurement unit; a block size detection sensitivity adjustment unit that adjusts block size detection sensitivities in block size detection based on the band level evaluated by the band level evaluation unit; and a block size detection unit that detects the block sizes of blocks in the input video signal by using the block size detection sensitivities adjusted by the block size detection sensitivity adjustment unit.
