Title:
CORRELATING DEVICE
Document Type and Number:
Japanese Patent JPS6084666
Kind Code:
A
Abstract:
PURPOSE:To display a correlative image on the entire output screen by obtaining the continuation of signal presence absence through an electric gate circuit. CONSTITUTION:An input image is picked up by a television camera, a correlator 101 performs auto-correlation or convolution arithmetic, and the obtained arithmetic output is inputted to an image receiving device 102 to display the correlative image. A synchronizing pulse delay circuit 7, gate pulse generating circuit 8, and two video signal gate circuits 9a and 9b are provided. The gate pulse generating circuit 8 opens gate circuits 9a and 9b for the time when correlation is performed and then closes the gate circuits 9a and 9b for longer than the time that it takes to propagate an ultrasonic wave in ultrasonic wave modulators ULM1 and ULM2 to light transmission width.
