<P>PROBLEM TO BE SOLVED: To set non-interactive image information, such as map information present on the Internet, as interactive image information. <P>SOLUTION: A communication part 8 stores to a RAM 4 color map information where image compression processing input by a Web server via a network is performed. A CPU 1 calculates a color distance between color information about the map image to be searched for that is contained in the color map information stored to the RAM 4 and color information about a plurality of reference images to be referred to for searching for a transportation phenomenon, determines whether or not the calculated color distance satisfies a condition that a color distance is equal to or lower than the threshold TH 1 and, when it is determined that the condition is satisfied, the CPU performs image processing so that an area of the map image corresponding to a reference image determined to satisfy the condition is displayed in relief, and output to a display part 7. <P>COPYRIGHT: (C)2011,JPO&INPIT |
