PURPOSE:To facilitate setting of an address necessary for scanning a required area by writing only the address where binary coded data in the required area is equal to image data on a scanning address table and reading out the image data. CONSTITUTION:The binary coded image data available from an image sensor scanning circuit 5 is stored in a frame memory 6, outputted to a video signal generator circuit 11 together with pattern data stored in a display pattern memory 10 and displayed on a display means 12. An operator inputs values of image data necessary for pattern discrimination, etc., to an image processing part 7 through a keyboard 13. An address selecting circuit 14 outputs only the address where input data is equal to the image data from the frame memory 6 to a scan address selecting circuit 8 and writes it on the scanning address table 9. The image data in an optic random access memory 4a are scanned on the basis of the address of the address table 9. |
