VIDEO PROCESSING DEVICE, VIDEO PROCESSING METHOD, VIDEO PROCESSING PROGRAM, AND MEMORY MEDIUM

摘要

Provided is a video processing technique capable of carrying out noise reduction processing and image quality correction using a configuration that is typically used in decoding processing. A video processing device according to the present invention counts the number of blocks in which a quantization parameter in video exceeds a predetermined threshold value and calculates a noise amount in the video based on the count result. Further, an amount by which the noise is to be reduced is adjusted in accordance with the calculated noise amount.
