PURPOSE:To extract the characteristics of a plurality of patterns present in one screen every pattern, by using one distribution pattern of peripheral distribution method for pattern and discrimination, and referencing other distributions every pattern end. CONSTITUTION:A video signal obtained from an image sensor 4 picking up patterns by scanning two-dimensionally is into binary video element at a binary coding circuit 5. The signal indicating X axis coordinate among two-dimensional binary video element coded signals obtained from the circuit 5 is counted to form the distribution toward the X axis at an X distribution forming circuit 6. Further, every time the state of presence of one level of video element coded signal obtained from the circuit 5 toward the X axis is disappeared from the continuous state toward the Y axis, the X distribution read-out circuit 11 is controlled with a Y direction addition circuit 7 and a Y continuity discrimination circuit 10 referencing the distribution of the circuit 6. Further, the characteristics of a plurality of patterns present one screen are output every pattern via a pattern discrimination circuit 12. |
