Document Type and Number:
Japanese Patent JP2016118391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To appropriately perform route guidance regardless of outdoor and indoor by having no need of receiving radio waves from a GPS satellite and suppressing a processing load.SOLUTION: A storage part 102 previously stores map information obtained by associating position information with an image seen from the position of the position information. A reception part 101 sequentially receives image data from a communication partner, and also receives destination information. In the case that an image corresponding to an image of received image data is included in the map information, a control part 103 specifies the current place of the communication partner from the position information associated with the corresponding image, and performs a route guidance from the current place toward a destination specified by the destination information to the communication partner on the basis of a comparison result between the received image data and an image of the map information.SELECTED DRAWING: Figure 1
