BLOCK DISTORTION DETECTION DEVICE, BLOCK DISTORTION DETECTION METHOD, AND VIDEO SIGNAL PROCESSING DEVICE |
摘要 |
An edge is detected by inputting a video luminance signal and based on a luminance signal difference. The detected edge is composed by the number in accordance with the number of pixels included in a block and counted by a plurality of counters corresponding to a horizontal position of an image. Values of respective counters are evaluated to identify a block boundary position. By performing filtering processing on the pixel signal at the identified block boundary position, a block distortion is reduced. |
