Abstract
An image processing apparatus for removing block distortion comprises an area specifying unit 103 for specifying a block distortion area to remove the block distortion therefrom in a reconstructed image decoded from a compressed data, and a block distortion area noise removing unit 104 for removing the noise from the block distortion area.
Claims26
An image processing apparatus for a reconstructed image decoded from a compressed data of an original image, which comprising:
- an area specifying unit for specifying a block distortion area on the reconstructed image;
- and
- a block distortion area noise removing unit for removing a noise from the block distortion area.
An image processing apparatus for a reconstructed image decoded from a compressed data of an original image, which comprising:
- a magnifying ratio detecting unit for detecting the magnifying ratio of an output image to the reconstructed image;
- a noise removing unit for removing noises of the reconstructed image according to the magnifying ratio detected by the magnifying ratio detecting unit;
- and
- an image enlarging unit for enlarging the reconstructed image from which the noise removing unit removes the noises, according to the magnifying ratio.
An image processing method for a reconstructed image decoded from a compressed data of an original image, which comprising steps of:
- specifying a block distortion area from the reconstructed image;
- and
- removing a noise from the block distortion area.
An image processing method for a reconstructed image decoded from a compressed data of an original image, which comprising steps of:
- detecting the magnifying ratio of an output image to the reconstructed image;
- removing noises of the reconstructed image according to the magnifying ratio detected by the step of detecting the magnifying ratio;
- and
- magnifying the reconstructed image removed the noises in the step of removing noises by means of the noise removing unit, according to the magnifying ratio.
