Abstract

PURPOSE:To make it possible to display the video signal for a polar coordinate position in a radar or the like as the video signal synchronized with the synchronizing signal of a television by converting said video signal into a signal for a rectangular coordinate position in real time by using a scan converter. CONSTITUTION:The radar video signal obtained from the radar system 1 is converted in coordinates by the scan converter 2 and applied to the automatic video recording control unit 4, which discriminates whether or not there is any course obstacle in the specified region, and when detecting an obstacle, the unit 4 applies the video-recording start control signal through the change-over switch 6 to the picture memory 3. Thereby, the output of the scan converter 2 is stored in the picture memory 3. At the same time, the output of the scan converter 3 is also applied to the television display device 5.
