Abstract
PURPOSE: To secure the faithful reproduction of the picture as well as to realize a high-efficiency transmission of signals by drawing out the prescribed black picture element and white picture element deciding patterns and then delivering the each divided picture element after dividing it into four equal parts.
CONSTITUTION: The sampling information SGi obtained through the sensor is memorized in memory 1 to be then read out, and the predictive value is memorized in memory 2 for the non-sampling picture element averaged at average value arithmetic circuit 3. The output picture element density signal of memory 1 or 2 is quantized by level recorder 4 to be delivered to pattern memory 5. Memory 5 holds the signal as the address to memorize information 1 and 0 divided into four equal parts. Thus the information of each picture element is delivered via memory 5 in the form of output signal SGO divided into four equal parts. In such way, the prescribed black and white picture element patterns are drawn out and then divided into the square grid form, and each element is delivered through division into four equal parts. As a result, the faithful restored picture is obtained, at the same time realizing a high-efficiency signal transmission.
