Abstract
An image processing device configured to reduce noise of an image, including: a position control information generating unit configured to calculate a block boundary position for each of blocks and the distance of each pixel from the block boundary position, based on block size information and block boundary initial position, and generate position control information of said pixels; a block noise detecting unit configured to detect block noise feature information at said block boundary position, based on said position control information; and a noise reduction processing unit configured to reduce noise for each of said blocks, based on said block noise feature information.
Claims13
An image processing device configured to reduce noise of an image, comprising:
- position control information generating means configured to calculate a block boundary position for each of blocks and the distance of each pixel from the block boundary position, based on block size information and block boundary initial position, and generate position control information of said pixels;
- block noise detecting means configured to detect block noise feature information at said block boundary position, based on said position control information;
- and
- noise reduction processing means configured to reduce noise for each of said blocks, based on said block noise feature information.
An image processing method of an image processing device configured to reduce noise of an image, comprising the steps of:
- position control information generating arranged to calculate a block boundary position for each of blocks and the distance of each pixel from the block boundary position, based on block size information and block boundary initial position, and generate position control information of said pixels;
- block noise detecting arranged to detect block noise feature information at said block boundary position, based on said position control information;
- and
- noise reduction processing arranged to reduce noise for each of said blocks, based on said block noise feature information.
