Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image position specifying system in a mobile terminal for specifying a target position on an image displayed on the screen of the mobile terminal.

[0002]

2. Description of the Related Art Since a portable terminal does not have a mouse function in a personal computer and an entire image is treated as one data on an image screen, it is impossible to pinpoint a portion to be enlarged or reduced. To do this, for example,
When searching for a destination on the map, if the display screen is not the target screen, operate the buttons on the terminal up / down / left / right to move the entire display screen up / down / left / right to switch, or to enlarge / reduce the screen. The procedure is such that the target screen is obtained by receiving and replacing the screen.

However, when searching for a destination by moving an image such as a map, the entire screen is scrolled in half or the whole area, but when the specific area is narrowed down, the destination is not displayed on the screen. Comes out, and it is difficult to determine where and how much to stalle.

In the case of a map or the like, as means for specifying a position other than screen scrolling, an address, a station name, a zip code, etc. are specified by operating a button of a mobile terminal, etc., and the specified answer is transmitted, and the purpose is followed according to the contents Maps of the surrounding area are being sent.

There are various means for specifying the position of the destination, such as an address, a station name, and a zip code. In any case, the user who uses the mobile terminal has many procedures for specifying the destination. It is necessary to specify by inputting characters and numbers by operating buttons. In addition, if it is a mobile terminal between the user and the provider, it is necessary to repeatedly perform wireless communication to specify the position.

Address: For example, the Kanto region must be selected, Tokyo must be selected, and the number of Minami-Aoyama 1-chome, Minato-ku must be input while selecting each kanji and number. In the case of a station name, taking Omotesando Station as an example, you can select Hiragana by operating the buttons on your mobile phone, and then convert it to Kanji and input Omotesando. Even if the same station name is used, it is necessary to specify it by rail line. If the station is the destination, there are few, so you have to find another destination.
Although there is a specific method using a postal code, the user often does not know the postal code of the destination. In addition, since the postal code covers a wide area, it is necessary to further select the area to specify the destination.

The following are examples of means for specifying position information using hardware. A mobile terminal having a built-in GPS or having map data connected to a GPS antenna in a memory receives a GPS signal to fix the position, and displays the current position on an electronic map. The telecommunications carrier obtains location information by the location information system that measures the distance between the user's PHS and mobile phones and the closest multiple base stations. Based on the location information, the current location of the lost child, loitering person, etc. is obtained. Display on the electronic map of the mobile terminal.

[0008] One example of the procedure currently used to send a map is as follows.
(1) Select data transmission (for example, I-MODE menu) from the telephone or data transmission on the initial screen. (2) Select a menu from the menus for receiving data, mail, messages, etc. (3) Select another menu list from pre-registered menus in the menu, other menu lists, notices from communication carriers, options, and the like. (4) Select to send a map from news, weather, banking, travel, map, shopping, meal, etc. in the menu list. (5) Temporarily select the A type map from the A type map, B type map, C type map, etc. in the map menu. (6) Select the Kanto region from Hokkaido, Tohoku, Kanto region, etc. as the method of specifying the destination on the map. (7) Select Tokyo from Kanto area Tokyo, Kanagawa, Chiba, Saitama. (8) Select the map of Tokyo, search for the place, and select the map from other. (9) Select an address from the addresses on the map, station name, zip code, etc. (10) As the address, input the number of which street in Minato-ku. (11) When the confirmation of what number and number of the address in Minato-ku is sent, send "Yes". (12) As a result, the map is received.

The above procedure is one example, but the procedure up to the transmission of the map is complicated and time-consuming, and the data input also requires complicated procedures such as character input and numeric input by button operation.
