Abstract

Abstract PURPOSE: To obtain the excellent picture quality by averaging the information value having the plural adjacent picture elements feature and then displaying the averaged value in the form of one picture element. CONSTITUTION: The video signal drawn out at video detection circuit 401 undergoes the A/D conversion through A/D converter 404 and is then memorized temporarily in auxiliary memory circuit 403. And the contents is memorized in main memory circuit 406 within the blanking time of each scan line. Then the adjacent information of the necessary number in the vertical, horizontal and oblique directions of each picture element are read out and then averaged through process circuit 414 in a digital way. The averaged signal undergoes the D/A conversion through D/A converter 409 to be returned to the original video signal. And row driver 410 scans each row in sequence. Then the lines are also scanned sequentially via line driver 411 and based on the reading velocity. For each picture element thus driven, the peripheral information to be sampled are also averaged to be displayed. Thus, the high-quality picture can be obtained even with a small number of picture elements. COPYRIGHT: (C)1980,JPO&Japio
