Abstract
PURPOSE: To realize varied position detection, by extracting picture elements in the extraction range in a specified pattern, and extracting picture elements successively from the reference part of the picture plane, then finding a position in the extraction range in which this extraction signal value coincides with the detected value of the relation between the point forming an angle and the pattern.
CONSTITUTION: Extraction is carried out by moving the extraction range 5 successively as X1, Y1→X2, Y1→Xn, Y1. When the extraction range 5 runs through part 3 of a picture plane 1, the values of picture elements in the extraction range 5 all become 1. As a result, the output of an AND gate 12 becomes 1, and the output of an OR gate 14 becomes 0. Therefore, no output is delivered to an AND gate 15, and counter 18, shift register 111W118 hold their state at this point. This means the extraction range 5 has reached the desired position, and the position of the extraction range 5 can be recognized from the values of counters 18, 22. By finding this position of extraction range 5, the position of a desired pattern 2 may be calculated from the relation to point 6.
