20 points are added if the elapsed time from the time of shooting is 16 minutes or more and less than 18 minutes.
If the elapsed time from the time of shooting is 18 minutes or more and less than 20 minutes, 10 points are added.

  That is, the control unit 101 gives more points to the image related to the photographed subject as the elapsed time from the time when the subject was photographed by the user is shorter.

  When the control unit 101 completes the above point addition processing, the control unit 101 uniformly adds a predetermined number of points (for example, one point) to [points] of all data records included in the image management DB 1021. With the uniform addition of points, a positive probability is calculated in the probability calculation described below even for an image that has not been subjected to point addition in the above-described point addition processing. For this reason, all images may be used in the display of wallpaper.

Subsequently, the control unit 101 includes a total of n data records included in the image management DB 1021 and sets [point] of the kth data record (k is an arbitrary natural number satisfying 1 ≦ k ≦ n). When the stored data value is P _k , the probability R _k corresponding to the k-th data record is calculated according to the following Equation 1.

Subsequently, the control unit 101 selects a predetermined number (hereinafter, five) of images from the images registered in the image management DB 1021 according to the probability R _k calculated as described above.

  Subsequently, the control unit 101 confirms whether or not image data indicating the selected five images is stored in the storage unit 102. For image data not stored in the storage unit 102, the image ID of the image data is stored. Is transmitted to the server apparatus 11 via the communication unit 103. At that time, login processing for the server device 11 of the terminal device 10 is performed as necessary.

  When the control unit 111 of the server device 11 receives a transmission request from the terminal device 10 via the communication unit 113, the control unit 111 reads image data identified by the image ID included in the transmission request from the storage unit 112, and transmits the image data via the communication unit 113. To the requesting terminal device 10. When the control unit 101 of the terminal device 10 receives image data sent from the server device 11 via the communication unit 103, the control unit 101 stores the received image data in the storage unit 102.

Subsequently, the control unit 101 uses the image data of the five selected images to generate wallpaper image data indicating one wallpaper image obtained by synthesizing the five images. In the generation of wallpaper image data, the control unit 101 determines the ratio of the sizes of the five images in the wallpaper, for example, according to the following Expression 2. However, in Expression 2, S _{1 to} S ₅ indicate the ratios of the sizes of the images 1 to 5 in the wallpaper when the images 1 to 5 are in descending order of the probability R _k .

Further, in the generation of wallpaper image data, the control unit 101 determines the ratio of the density of the five images in the wallpaper, for example, according to Equation 3 below. In Expression 3, C ₁ -C _5, when the image 1 to the image 5 in order ratios R _k is large, respectively, showing the ratio of the concentration in the wallpaper IMAGES 1 through 5.

The control unit 101 instructs the display unit 1041 to display wallpaper according to the wallpaper image data generated as described above. The terminal device 10 assigns the above-described points, calculates the probability R _k based on the points, selects image data according to the calculated probability R _k , and selects the selected image data every time a predetermined time elapses (for example, every minute). A series of processes of generating wallpaper image data using and displaying wallpaper according to wallpaper image data is repeated. As a result, an image corresponding to the environment in which the terminal device 10 is placed is displayed on the display unit 1041 with high probability on the wallpaper.

  FIGS. 11-16 is the figure which showed typically the content of the wallpaper which the terminal device 10 displays in the image display system 1. FIG. FIG. 11 is a diagram illustrating a state in which a photograph taken by a user on the day in the past is displayed with a high probability on a wallpaper of the terminal device 10 when a specific day in one year approaches. As described above, according to the image display system 1, since a photograph taken on a date close to a different year in the past is displayed on the wallpaper with a high probability, the user remembers, for example, the memory of the same time in the past through the wallpaper. be able to.

  FIG. 12 is a diagram illustrating a state in which, when the user goes near a specific place, photographs taken around the specific place are displayed on the wallpaper of the terminal device 10 with high probability. As described above, according to the image display system 1, an image related to the location where the user is present is displayed on the wallpaper with a high probability, so that the user can know the famous places near the current location through the wallpaper, You can remember the memories of visiting the same place in the past through wallpaper.

  In FIG. 13, when the user is at or near the home, a picture of a family member or friend is displayed with a high probability on the wallpaper of the terminal device 10, and when the user is at or near the workplace, a landscape photograph or the like is displayed on the wallpaper of the terminal device 10. It is the figure which showed a mode that is displayed with high probability. As described above, according to the image display system 1, an image suitable for the location where the user is present is displayed on the wallpaper with a high probability, so that the inconvenience that only private photos are displayed on the wallpaper in the workplace is avoided. Is done.

  FIG. 14 is a diagram illustrating a state in which an image related to an event is displayed with high probability on the wallpaper of the terminal device 10 when an event registered in the schedule approaches. As described above, according to the image display system 1, when an event registered in the schedule approaches, an image related to the event is displayed on the wallpaper with a high probability. Can be noticed through the wallpaper.

  FIG. 15 is a diagram illustrating a state in which an image related to the keyword is displayed with high probability on the wallpaper of the terminal device 10 when the user utters the keyword. Thus, according to the image display system 1, the user can display an image having a desired content on the wallpaper with a high probability by uttering a keyword.

  FIG. 16 is a diagram illustrating a state in which a photograph of a person is displayed with high probability on the wallpaper of the terminal device 10 when the user captures a person. Thus, according to the image display system 1, the user can display a photograph of the person on the wallpaper with a high probability by photographing the person.

As a result, the user can feel the convenience of the image display function. Moreover, according to the image display system 1, since the image displayed on the terminal device 10 is selected according to the probability, the same image is not always displayed even in the same environment. Therefore, the user can see these images without getting tired without feeling monotonous in the displayed images.

[Modification]
The above-described embodiment is a specific example of the present invention and can be variously modified. Examples of these modifications are shown below.

(1) The above-described embodiment is an example in which the present invention is applied to the wallpaper switching function. However, the present invention is not limited to the wallpaper switching function, and a part of images are selected and displayed from a plurality of images. Any function can be applied.

  For example, even when a list of images indicated by image data stored in the terminal device 10 or the server device 11 or thumbnail images of the image is displayed on the display unit 1041 of the terminal device 10 in response to a user operation, The present invention is applicable. In that case, the terminal device 10 displays, for example, an image group selected with a probability according to the environment in which the terminal device 10 is placed on the first page, and from among the images not displayed on the first page. Similarly, the image group selected with a probability corresponding to the environment where the terminal device 10 is placed is displayed on the second page, and so on.

(2) In the above-described embodiment, a configuration is adopted in which an image to be displayed is selected according to the probability according to the environment where the terminal device 10 is placed. Instead of this, or in addition to this, a configuration in which the image display mode is selected from a plurality of options according to the probability according to the environment in which the terminal device 10 is placed may be employed.

For example, as the display mode of the image, the size, density, animation display (flashing, etc.) of the image can be considered. For example, when there are two options for the image size, large and small, and one screen can display a total of five images, one large image and four small images. think of. In this case, after the control unit 101 randomly selects five images from the available images, the probability Rq (where q is five for each of the five images, for example, according to Equation 4 below) A natural number of 1 to 5 corresponding to each of the images, and P _q is a point of each of the five images.

Subsequently, the control unit 101 selects one image to be displayed in a large size from among the five images according to the probability R _q calculated as described above. The control unit 101 instructs the display unit 1041 to display one image thus selected in a large size and the other four images in a small size. As a result, an image corresponding to the environment where the terminal device 10 is placed is displayed with a higher probability and a larger size.

  The above example is an example in which the size is changed as the display mode of the image, but the same applies to the case of changing other types of display modes such as density and animation display in the display of the image. In the above example, the number of display mode options is two (large and small), but the number of options may be three or more.

  According to this modification, for example, a specific image corresponding to the environment in which the terminal device 10 is placed is high such that a photograph taken at a position close to the current position of the user is displayed with high probability. Prominently displayed with probability. As a result, the user can feel convenience from the displayed image and is not monotonous.

(3) In the above-described embodiment, a configuration in which a part of image data usable in the terminal device 10 is stored in the server device 11 is employed. Instead of this, a configuration in which all image data that can be used by the terminal device 10 is stored in the terminal device 10 may be employed. In that case, the server device 11 is not required in the image display system 1.

(4) In the above-described embodiment, a configuration in which the selection process of the image displayed on the terminal device 10 is performed on the terminal device 10 is employed. Instead of this, a configuration in which the server device 11 performs a selection process of an image displayed on the terminal device 10 may be employed. In that case, the server apparatus 11 is provided with functional configuration units corresponding to the image attribute data acquisition unit 122, the environment attribute data acquisition unit 123, and the control unit 124 included in the terminal device 10, and the server apparatus 11 sets the environment attribute data ( For example, the current position data indicating the current position of the terminal device 10 may be received from the terminal device 10, the image data may be selected, and the selected image data may be transmitted to the terminal device 10.

(5) In the above-described embodiment, a configuration in which data related to the reference position is registered by user input is adopted, but the method of registering data related to the reference position is not limited to this. For example, the control unit 101 of the terminal device 10 estimates a position that stays on average for a predetermined time or more in the daytime period as a workplace position, and stays on average for a predetermined time or more in the nighttime period. A configuration may be employed in which the current position is estimated as the home position, and the estimated position is automatically registered in the reference position management DB 1023 as the reference position.

(6) In the above-described embodiment, when the function of changing the probability of selecting an image by shooting with the camera 106 is used, the user gives a shooting instruction, and based on the image shot when the instruction is given, A configuration is employed in which the probability of image selection is changed. In addition to this, or instead of this, the terminal device 10 is configured such that the camera 106 continuously captures the outside world and selects an image relating to the subject indicated in the image data sequentially generated by the capturing with a high probability. May be. In this case, for example, when the camera 106 is arranged in a direction to capture the face of a person who views the display unit 1041 of the terminal device 10, an image related to the user watching the terminal device 10 is selected and displayed with a high probability. Will be.

(7) In the above-described embodiment, when the function of changing the image selection probability by photographing with the camera 106 is used, the image selection probability is related only to the subject whose feature data is registered in the subject management DB 1024 in advance. Increased configuration is adopted. Instead of this, even when a subject whose feature data is not registered in the subject management DB 1024 is photographed in advance, a configuration in which a photograph related to the subject is selected with a high probability may be employed. In this case, the terminal device 10 generates facial feature data indicated by the image data regarding all the image data indicating the photograph of the face of the person among the available image data, and the person newly photographed by the camera 106. What is necessary is just to comprise so that a matching process may be performed between the feature data of a face.

(8) In the above-described embodiment, the terminal device 10 employs a configuration in which the display unit 1041 is built. Instead of this, the terminal device 10 may not include the display unit 1041, and a configuration in which the control unit 101 instructs the display device connected to the outside to display an image may be employed.

(9) In the above-described embodiment, when the current time is close to a specific time, the probability that an image related to that time is selected is high, and the current time and the time indicated as the attribute of the image Are compared on a yearly basis. The unit of time comparison is not limited to a year unit, and may be a month unit, a week unit, or a day unit, for example. For example, when comparing day by day, an image corresponding to the daily rhythm of the user is displayed, such that the closer to the evening, the higher the probability that a photograph taken in the evening will be displayed. It will be.

(10) In the above-described embodiment, when the current time is close to a specific time, the probability that an image related to that time is selected increases, and as the current time approaches that time, The probability that an image to be selected is gradually increased, and after that time has passed, the probability that an image related to that time is selected is gradually reduced. Instead of this, a configuration may be adopted in which after a specific time has passed, the probability of selecting an image related to the specific time is not increased.
