Abstract

PURPOSE:To make it possible to make a display over the entire screen with video signal made even in quality, by providing an access frequency controller that provides control over a frequency in access to a video memory. CONSTITUTION:A video signal from a radar transmitter-receiver is written in alternate buffer memories 102A and 102B via quantizer 101. Data read out of buffer memories 102A and 102B by turns are inputted to integrator 103 and extraction memory 104 receives outputs from integrator 103 or buffer memories and, when an extraction trigger is inputted, is stored with data as many as N at a time. An extraction video signal from extraction memory 104 is inputted to video memory 111 via large-amplitude priority circuit 116 and, after coordinate conversion is done, displayed on CRT122 by way of D/A converter 117 and video amplifier 121.
