Abstract
PURPOSE: To synchronise the respective image signals of the amending field and the field in which the pattern in to be recognized and read them and make binary with accuracy by inverting the phase of one of the signals and adding.
CONSTITUTION: The switch SW at the output of the TV camera 2 is disposed at the signal process circuit 3 and the half tone image signal obtained through the camera 2 of the amending field 1 is directly written in the magnetic disc through the circuit 3. Then the switch is changed over, the image signal obtained through the camera 2 of the field 1' in which the pattern is to be recognized is synchronized with the signal stored in the disc 4 through the timing control circuit 6 and read 5, and the phase of one signal is inverted and added 7, to input to the binary pattern circuit 9. Thus, the signal composition due to the camera, illumination and the like is removed and the binary with accuracy can be obtained.
