Abstract: Provided is a method for a plurality of processing elements to filter a plurality of pixel blocks in a plurality of picture partitions for a single frame image. The method for filtering pixel blocks includes: checking the status of a second boundary pixel block adjacent to a picture partition boundary, the second boundary pixel block being one of a plurality of pixel blocks in a second picture partition and neighboring a first boundary pixel block in a first picture partition, the first boundary pixel block neighboring the picture partition boundary; selecting a filtering area for the first boundary pixel block based on the status of the second boundary pixel block; and filtering the filtering area for the first boundary pixel block.

Abstract: Disclosed are a method and a device for processing an image by using image division capable of simultaneously minimizing deterioration of an image quality due to an error in a transmission line and further improving compression efficiency in performing compression and restoration of an image signal by using multiple processors. The method of processing an image by using image division according to an exemplary embodiment of the present disclosure includes dividing an image frame into multiple subblocks having a predetermined pixel size; constituting multiple macroblocks by sampling respective pixels positioned at an identical position within a predetermined number of subblocks; and constituting multiple slices by dividing the multiple macroblocks based on the positions of the sampled pixels within the subblock.
