PURPOSE:To easily select an individual graphic by extracting a color on a position specified by a color extracting means, extracting graphics having the same color extracted from a code memory by a graphic extracting means and extracting only a graphic existing in the specified position in its graphic by an inner point deciding means. CONSTITUTION:When a point X is indicated by an indication part 101 in order to indicate a graphic 201, its positional information is outputted to a color extraction part 106. The color extraction part 106 reads out information on the specified position of a display memory 104. When the display memory 104 is a memory consisting of single layers of R, G, B for instance, the color on the indicated position (Fig.201) is yellow, R=1, G=1 and B=0 are read out and yellow is decided. A graphic extraction part 107 inspects the contents of a code memory 103 and extracts graphics having the same color. When the graphics 201, 205 to be yellow graphics are extracted by the extraction part 107, whether the graphics are superposed to an indicated point or not is decided by an inner point deciding part 108 and the graphic 201 superposed to the indicated point X is extracted. |
