<p><P>PROBLEM TO BE SOLVED: To provide a technology for detecting at high resolution, a position read by a reader on a display face that a display device has. <P>SOLUTION: A control device 303 includes: a display control part 305 for executing processing to successively display dots with luminance shown by luminance information ranging from the head to the tail by using a prescribed time as a cycle according to pattern information associated with positional information stored by a storage part 304 at each position shown by each of the position information; a dot reading control part 307 for executing processing for reading dots present in a reading region among dots displayed on the display face in each prescribed time; and a positional information acquisition part 306 for acquiring the luminance information showing the luminance of the dots on the basis of the read data of the dots read in each prescribed time by the reader, and for acquiring the positional information associated with the pattern information configured by arranging the prescribed number of pieces of obtained luminance information from the head to the tail in the order of the reading of the dots from the storage part 304. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
