A portion within an image in which a plurality of objects (21 and 22) overlap is partitioned into a plurality of small regions (31a and 32a), each of the units of identification information for the plurality of objects (21 and 22) is assigned to a dot corresponding to the plurality of small regions (31a and 32a), and thereby, identification-use layout information is generated, whereby even if a plurality of objects overlap upon a layout of a display image, upon the layout of the identification-use layout information that has been generated for identifying the plurality of objects, the identification information corresponding to each object does not overlap. As a result, it is possible to identify each object by the identification information acquired from the position of the cursor. |
