A line buffer device temporarily stores a predetermined area of original image data which are divided into small blocks, each having a small area, so as to encode the image data for each block into data having a fixed length by a compression processor. The line buffer device is composed of a first-stage line buffer group and a second-stage line buffer group. The number of line buffers in the first-stage line buffer group is smaller by one than the number of lines constituting one block and the number of line buffers in the second-stage line buffer group is the same as the number of lines constituting one block. Encoding processing time is shortened and the circuit structure is simplified.
