IPC: H04N5/91
Filed: 1989-07-17
Abstract: PURPOSE:To save memory capacity by providing a gradient compression means which compresses the gradient of a digital image signal and stores it in a memory, and a switching means which switches the operating and non-operating states of the gradient compression means selectively, CONSTITUTION:A selection signal which decides whether or not the gradient from a gradient compression selection switch 10 should be compressed is inputted to a control unit 9, and also, a comprssibility instruction signal from a compressibility selection switch 11 as a compression level varying means is inputted to the unit. A serial signal on which a gradient compression processing is applied is converted to the parallel signals with a serial-parallel converter 12, and is stored in the memory 13 when eight bits are compressed to three bits. Therefore, only information of one picture element is recorded on data 1, 2, and 3 whose addresses are designated ordinarily, and the information of three picture elements can be obtained from the data 1, 2, and 3, however, the information of eight picture elements can be recorded with 24 bits in the data 1, 2, and 3 by performing gradient compression, which saves the memory capacity required for the recording of one image.
