INFORMATION COLLECTING DEVICE, MOBILE TERMINAL DEVICE, INFORMATION CENTER, AND NAVIGATION SYSTEM

PROBLEM TO BE SOLVED: To provide a navigation system that can precisely guide a route in such a manner that collected information such as image data is accurately correlated to an address and a position (a latitude and a longitude) of a collection point and can reduce a collection time and collection cost of information, and to provide an information collecting device, a mobile terminal device and an information center. SOLUTION: This information collecting device 100 for collecting information to be used in the navigation system includes an imaging section 105 for imaging a peripheral portion of a predetermined location, an address input section 106 for inputting address information of the predetermined location, an image data storage section 107 that stores the image data imaged by the imaging section 105 in such a manner that the image data is correlated to address information input via the address input section 106, a wireless communication section 110 for communicating with the information center while being connected to a public wireless network, and a control section 104 that reads image data from the image data storage section 107 and transmits the image data to the information center together with the address information to the wireless communication section 110.
