<p>PURPOSE:To perform effective processing with small memory capacity by extracting a pattern in a specific shape from a picture having plural picture patterns, arranging and displaying plural patterns, and storing patterns with good concatenation as a basic pattern repeatedly. CONSTITUTION:Cursors 13a and 13b which are at a specific interval are positioned on a pattern 11 and a rectangular pattern Sa determined by points 14a- 14d is extracted from the pattern 11. Then, the pattern Sa is displayed on a display device 44 such as a CRT repeatedly in two up-down directions. Then, whether the concatenation between repetitive patterns is good or not is confirmed visually. The cursors 13a and 13b are moved gradually to alter the pattern Sa until a clean picture is obtained. Patterns which coincide with the interval of repetition are stored in a storage device 45 as the basic pattern. Thus, the pattern is generated efficiently with small storage capacity.</p> |
