Abstract: An apparatus and a method for applying an independent compression mode for encoding on each data block constituting an image frame in an encoder provided in an image processing device are provided. To that end, at least one data block is encoded based on each of a plurality of specified compression modes, and at least one data block corresponding to each of the plurality of specified compression modes is reconfigured based on at least in part on each of the plurality of specified compression modes. An inter-data difference corresponding to each of the plurality of specified compression modes is determined based on the at least one data block and a data block obtained by reconfiguring the at least one data block, and at least one compression mode is selected from the plurality of specified compression modes based on at least in part on each of the inter-data difference.

Abstract: An image processing device and method for an image processing device to compress, for each line, an image frame formed of a plurality of lines are provided. The method includes predicting an image quality of each line forming a single image frame, independently determining a compression rate of each line so as to obtain the image quality predicted for each line, and compressing an image data of a predetermined line of the single image frame by using a compression rate independently determined for the predetermined line.
