At this time, when the user B holds the information terminal 1b over the paper used at that time and brings the information terminal 1b close to the paper, an inquiry is made to the server 2 via the communication network. Based on the information notified from the server 2, the information terminal 1b displays an inquiry screen indicating whether or not to install an application. When the user B installs the application, the user B can easily own the same application by proceeding according to the instructions on the screen.
- FIG. 7 is an explanatory diagram illustrating an example of a situation in which the information processing apparatus of this specific example is used.
- a display device is provided on a surface referred to by a user, and a camera (not shown) is provided on the back surface of the display device.
- the user activates the program of the present invention on the information terminal 1 in a bookstore or library. Then, as shown in FIG. 7A, the user takes an image of the cover by holding the information terminal 1 over the cover of the book or magazine that is of interest, and temporarily stores the taken image on the information terminal.
- the information terminal 1 determines that a flat image is input by inputting a completely dark image. Therefore, the information terminal 1 transmits the image of the cover that is held up to a server provided in the bookstore or library.
- the server performs image collation between the transmitted cover image and the registered image, and returns the electronic book data of the matched book or magazine to the information terminal 1.
- the information terminal 1 activates an electronic book reader application based on the returned data, and displays the electronic book data. Therefore, the user can browse the contents of the book or magazine by simply placing the information terminal 1 on the cover of the book or magazine.
- the information terminal 1 may be limited so that the electronic book data can be browsed only when the information terminal 1 exists within a predetermined range. For example, when the user completes the purchase procedure at the bookstore or completes the loan procedure at the library, the information terminal 1 can continue to view the electronic book data even if it is taken out of the area. You may control. In addition, when the user has not completed each procedure, the information terminal 1 may be controlled so that the electronic book data cannot be browsed outside the area when it is taken out of the area.

- Information stored in the memory or information processing specified by the information representing the input image data for example, application execution processing, additional information presentation processing
- Information processing execution means 85 (for example, central processing means 102).
- the information terminal has a large storage capacity, and many applications can be installed. However, when many applications are installed, it tends to be difficult to find an application that you want to use. For this reason, the operation summary manual is not read, and applications that are not used at all are often held in the information terminal.
- the application when the user reads the manual and finds a favorite application, the application can be started by placing or moving the information terminal on the page. Furthermore, in this case, an effect that the operation of the application can be easily learned by operating according to the description of the manual as it is can be obtained. Therefore, an application that occupies a storage unit in the information terminal even though it is not used can be effectively used.
- the camera image input means 81 may be provided with a stationary state determination means (for example, vibration detection means 106) for determining whether or not the camera image input means 81 is in a stationary state. Then, the information processing execution means 85 is stored in the memory when it is determined that the new input image data is data indicating a flat image and the camera image input means 81 is in a stationary state. Information processing specified by the input image data or information representing the input image data may be executed.
- a stationary state determination means for example, vibration detection means 106

- Information processing specified by the input image data or information representing the input image data may be executed.
- the image matching unit 82 temporarily stores the input image data that has not been determined to match or the feature amount of the input image data (for example, Temporary storage data may be stored).
- the information processing execution means 85 is a case where the new input image data is determined to be data indicating a flat image, and when the input image data or information representing the input image data is not stored in the memory, Various information (for example, information required for the information processing apparatus (for example, the information terminal 1) to execute information processing on the input image data temporarily stored based on the input image or the feature amount of the image) , An application name or information to be presented) may be transmitted to a searchable server (for example, server 2), and information processing specified by information notified by the server may be executed.
- a searchable server for example, server 2
- the image collating unit 82 may calculate the feature amount of the input image data input by the camera image input unit 81 and determine whether or not it matches the feature amount of the image data registered in advance.
- the image flatness determining unit 84 may determine that the image data is data indicating a flat image when the calculated complexity of the image data is equal to or less than a predetermined threshold.
- the information processing execution means 85 performs processing for starting an application related to the latest input image data stored in the memory as information processing to be executed, or processing for displaying additional information related to the input image data. May be.
- the present invention is suitably applied to a user interface that operates an application associated with an object such as a poster or a magazine by bringing the information terminal close to an object such as a poster or magazine on an information terminal equipped with a camera.
