Abstract: A video encoding method includes: receiving an image; up-sampling the received image; and changing a sample value of an up-sampling region included in the up-sampled image and encoding the up-sampled image by using the changed sample value, wherein the up-sampling region is a region inserted into the received image by the up-sampling.

Abstract: Provided are a method and an apparatus for decoding an image by accessing a memory by a block group. The method comprises checking information regarding a size of one or more blocks included in a bitstream of an encoded image, determining whether to group one or more blocks for performing decoding, based on the information regarding the size of the one or more blocks, setting a block group including one or more blocks based on the information regarding the size of the one or more blocks, and accessing a memory by the block group to perform a parallel-pipeline decoding process by the block group.

Abstract: An image correction method includes: obtaining information regarding at least one of brightness and colors of pixels constituting an input image, the input image comprising a plurality of regions classified according to whether the at least one of the brightness and the colors of the pixels are substantially uniformly distributed in a corresponding region; determining a weight with respect to at least one pixel based on the obtained information; and correcting the input image with respect to the at least one pixel based on the determined weight.
