Filed: 1981-09-08
Abstract: PURPOSE:To prevent pictures from changing abruptly and to obtain easy-to-see display pictures by comparing a received signal stored in a memory with a received signal and updating storage contents only according to the variation. CONSTITUTION:A received ultrasonic-wave signal stored in a memory 9 is compared by a comparator 5 with a received ultrasonic-wave signal passed through an A/D converter 4, etc., and when they have no difference, the low-level output of the comparator 5 is applied through an inverter 6 to open an AND gate 8, thereby re-storing the readout contents of the memory 9 in a memory 8 through the gate 8. Therefore, a signal read out of the memory 8 through an AND gate 7 has only a varied part modified, and then the contents of the memory 9 are updated to prevent display pictures on a cathode-ray tube 10, which correspond to the contents of the memory 9, from changing abruptly.
