Abstract: An object display device calculates a setting value including the focal length for acquiring an image in real space with a camera setting value determination unit based on the distance to a virtual object calculated by a virtual object distance calculation unit, and acquires the image in real space with an imaging unit using the calculated focal length. Thus, an image that is in focus in a position where the virtual object is superimposed and becomes more out of focus as the distance increases from the position where the virtual object is superimposed is acquired. Since the virtual object is superimposed on the image in real space acquired in this manner, the virtual object that is the subject of attention for a user is emphasized, and a sense of incongruity in the superimposed image is reduced.

Abstract: Information transmission requests are delivered to communication terminals existing in a specific area, to collect information held in the communication terminals, without inducing congestion. In an information collecting device included in an information collecting system, terminal information and capacity information are acquired based on base station identifying information, and information of an information amount of collected information is further acquired based on a collected information type that identifies a type of the collected information. In an information collection controlling unit, transmission timing information, designating the timing at which a capacity of performing communication via a base station is not exceeded, is generated based on the terminal information, the information-amount information and the capacity information, and an information transmission request including the transmission timing information is delivered to a communication terminal.

Abstract: An object display device includes a virtual object process unit that processes an object based on imaging information that an imaging unit references upon acquisition of an image in real space, an image synthesis unit that superimposes the processed object on the image in real space, and a display unit that displays a superimposed image. Accordingly, the feature of the image in real space is reflected in the object superimposed. Thus, a sense of incongruity upon superimposing and displaying the object on the image in real space is reduced.

Abstract: In an object display device, a pattern extraction unit extracts a region where an object is easily visually recognized when the object is overlaid and displayed in an image in real space, from the image in real space, based on information about the size and color of the object and information about the color of the image in real space that are acquired by an image analysis unit, and a display position correction unit corrects the display position of the object to this region. This facilitates visual recognition of the object and enhances various effects, such as informativeness, brought about by the displaying of the object in the image in real space.

Abstract: A data distribution server, a mobile terminal, and a data distribution method perform distribution of data in consideration of memory capacity. In a mobile terminal, an amount-of-space arithmetic unit carries out an arithmetic operation for an amount of space and a possible amount of space of an object storage unit. Then, in an object distribution server, object data is selected based on the amount of space or the like, and a distribution list is generated and transmitted to the mobile terminal. In the mobile terminal, deletion of object data determined as deletable is performed in order to acquire object data in the distribution list. Acquisition of the object data is then performed.

Abstract: In an object display device, in the case that a marker is not detected at present, a display complementing unit acquires a change in an image in real space displayed on a display unit between the past when the marker was detected and the present. Since a virtual object is displayed based on the position and shape of the marker in the image in real space, the display position and display manner of the virtual object are also to be changed in accordance with a change in the image in real space. A display decision unit can therefore decide the display position and display manner of the virtual object at present from the display position and display manner of the virtual object in the past, based on the change in the image in real space between the past and the present.

Abstract: In an object information provision system, at least one matching data is transmitted from an object information provision device to a terminal, and a result of image analysis based on the matching data is transmitted from the terminal to the object information provision device, and the amount of information of matching data is adjusted based on the image processing result. The success or failure of extraction of a valid physical object represented by the matching data in the terminal is thereby reflected on the amount of information of matching data.

Abstract: An object management device includes a distribution range setting unit that sets a range where an object is visible as a distribution range of object information related to the object for each of the object information based on a located position of the object and map information. Consequently, when the mobile terminal is located in the position where the object is visible, the object information of the object is distributed to the mobile terminal. It is thereby possible to appropriately distribute object information to be distributed so as to appropriately display the object on the mobile terminal.

Abstract: In a terminal location specifying system, landmark information of a landmark located within a specified distance from an approximate position is retrieved based on approximate position information of a mobile terminal, and the retrieved landmark information is transmitted to the mobile terminal. The mobile terminal can thereby acquire the landmark information about the landmark located in the vicinity of the mobile terminal. Further, because the landmark information pre-stored in a server is transmitted to the mobile terminal, it is possible to reliably specify the position of the mobile terminal based on the landmark image. Then, the photographing position of the image is analyzed based on the landmark image, and the photographing position is managed as the located position of the mobile terminal and used for position correction, and it is thus possible to accurately specify the position of the mobile terminal.

Abstract: In an object displaying apparatus, when, in the case where a virtual object is displayed superimposed on an image of the real space according to information about the layout position of the virtual object, the virtual object is displayed overlapping a superimposition inhibit object, display control is performed to display the virtual object transparently so that the superimposition inhibit object is not hidden by the virtual object. It is thereby possible to preferentially display the superimposition inhibit object.
