摘要： A memory mapping apparatus and a method in a video decoder/encoder utilize a dividing unit, a storage unit and a memory allocation unit. The dividing unit divides picture data into macroblocks and divides each of the macroblocks, which are units of encoding, into partitions having a predetermined size. A storage unit comprises at least one memory bank which is independently accessible. A memory allocation unit allocates adjacent partitions to different memory banks. Accordingly, a total number of cycles necessary to read and write the picture data is reduced.

摘要： A pipelining decoding apparatus and method, and a computer-readable recording medium for storing a computer program for controlling the pipelining decoding apparatus. Pixel values of each of the recovered images corresponding to previous macroblocks are stored as neighboring pixel values. Motion is predicted in a picture corresponding to a current macro block using the stored neighboring pixel values. An original image is recovered from the current macroblock using the result of the prediction of the motion in the picture and residue information. Some of the pixel values of the recovered image corresponding to the current macroblock are stored and the recovered image is deblocking-filtered.

摘要： Provided is an apparatus and method for super-resolution enhancement processing. The apparatus includes a low-resolution image capturing unit, a patch pair generating unit, a patch pair database, and a high-resolution image reconstructing unit. The low-resolution image capturing unit captures a low-resolution image. The patch pair generating unit divides each of a plurality of high-resolution images into patches and generates a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches. The patch pair database stores the plurality of patch pairs generated by the patch pair generating unit. The high-resolution image reconstructing unit divides the low-resolution image into patches, searches in the patch pair database for a patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generates a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image.
