Abstract
A method and apparatus for restoring an image by copying a memory may include determining whether to perform an interpolation operation based on block information, and restoring a current image using a reference image depending on whether to perform the interpolation operation.
Claims17
A method for restoring an image, the method comprising:
- determining whether to perform an interpolation operation based on block information of a current image;
- restoring the current image by copying a reference image to a memory address of the current image assigned in a memory based on a determination result, the reference image being stored in the memory;
- and
- wherein the determining further comprises:
- deciding whether to skip loading of the reference image,
- deciding whether to skip generating of a predicted image, and
- deciding whether to skip generating of a residual image and restoring of the current image, based on the block information.
A method for restoring an image, the method comprising:
- determining whether to perform an interpolation operation based on block information of a current image;
- and
- restoring the current image by copying a reference image to the current image based on a determination result, the reference image being stored in a memory,
- wherein the determining comprises, when a pixel value corresponding to motion information of the current image is already stored, determining whether to perform the interpolation operation based on weight information and skip mode information that are associated with the current image.
An apparatus for restoring an image, the apparatus comprising:
- at least one computer which acts as:
- an operation determination unit to determine whether to perform an interpolation operation based on block information of a current image;
- a memory to store the current image and a reference image associated with the current image;
- a restoring unit to restore the current image by copying the stored reference image to a memory address of the current image assigned in the memory based on a determination result;
- and
- wherein the operation determination unit decides to skip loading of the reference image, to skip generating of a predicted image, to skip applying of a weight, to skip generating of a residual image, and to restore the current image, based on the block information.
An apparatus for restoring an image, the apparatus comprising:
- at least one computer which acts as;
- an operation determination unit to determine whether to perform an interpolation operation based on block information of a current image;
- a memory to store the current image and a reference image associated with the current image;
- and
- a restoring unit to restore the current image by copying the stored reference image to the current image based on a determination result,
- wherein, when a pixel value corresponding to motion information of the current image is already stored, the operation determination unit determines whether to perform the interpolation operation based on weight information and skip mode information that are associated with the current image.
