摘要:
When image data of the first line is input, compressor 102 compresses the input image data by every prescribed number of pixels corresponding to the number of pixels included in column direction of one block, and the compressed data is stored in the corresponding region of a memory 104, under the control of control circuit 108. For the second and following lines, the compressed data of the last line which has been compressed and stored in the memory 104 and the input data are received by the compressor 102, and the compressor 102 integrates and compresses the received data, and the compressed result is stored in the corresponding memory region of the memory 104.
摘要:
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.
