The control device 30 includes an image acquisition unit 31, an image analysis unit 32, an arithmetic unit 33, an environmental information detection unit 34, a display control unit 35, a storage unit 36, and a communication unit 37.

[0015] The image acquisition unit 31 acquires the image captured by the imaging unit 20. The image analysis unit 32 extracts a predetermined object from the acquired image. Examples of the predetermined object include products sold in a predetermined store. The image analysis unit 32 performs image processing and the like on the acquired image, and can extract the object if the object is shown in the image. Note that in the storage unit 36 described later, data and the like for the image analysis unit 32 to perform various determinations in image processing are stored.

[0016] An object includes one or more elements. For example, when the object is clothing it will be described by way of example. Clothing has various elements such as genre (polo shirt, T-shirt, Y-shirt, trousers, etc.), shape (overall contour, each part: shape of collar, sleeves, buttons, pockets, etc.), dimensions (overall dimensions, each part: dimensions of collar, sleeves, etc.), color or pattern, material, etc.

[0017] When purchasing clothing, depending on the person or the time of purchase, etc., the preferences for the elements of the object differ. For example, regarding the type of clothing, there are people who prefer polo shirts and people who prefer T-shirts. Also, in summer, summer clothing is more likely to be preferred, and in winter, winter clothing is more likely to be preferred. In this embodiment, element data indicating the preferences (likes) of the purchaser (for example, the recipient) for the elements of such an object is stored as preference data in the preference storage section 36a of the storage unit 36. Also, the preference data may be set separately from the elements of the object. For example, the preference data may be set based on the purchaser's previous purchase history. Also, by obtaining information from the purchaser's smartphone, etc., the preference data can be set based on, for example, the Internet browsing history or search history, etc.

[0018] The arithmetic unit 33 obtains the preference matching degree of the object extracted by the video analysis unit 32 based on the preference data stored in the preference storage unit 36a. The preference matching degree is a value indicating the preference matching degree between the extracted object and the preference indicated by the preference data. When the arithmetic unit 33 obtains the preference matching degree, it calculates a score based on the similarity between the elements of the extracted object and the element data for the elements of the object stored in the preference storage unit 36a of the storage unit 36. Output and determine the degree of preference matching based on the total score. For example, the higher the score, the higher the degree of preference matching. Also, the lower the score, the lower the degree of preference matching. Further, for example, when the object is clothing, elements such as shape or color are important elements in selecting the object and have a great influence. Therefore, regarding the similarity of elements such as shape or color, weights can be assigned compared to other elements to calculate the score. Also, the arithmetic unit 33 may calculate the degree of preference matching in two levels of whether the score is higher or lower than a predetermined threshold value.

[0028] FIG. 4 is a diagram showing an example of the display content on the display unit 11 of the display device 100. When the user is detected by the environment information detection unit 34 as moving outdoors or indoors, the display control unit 35 can display an image of an object having an element preferred by the recipient among the objects for purchase on the display unit 11. As shown in FIG. 4, the display control unit 35 can, for example, show an image of the object in a predetermined display area 12 of the display unit 11. Note that in FIG. 4, videos other than the image of the object are omitted. Incidentally, in FIG. 4, videos other than the image of the object are omitted.

[0029] At this time, the display control unit 35 can adjust the number of objects to be displayed on the display unit 11 according to the environment information. For example, the display control unit 35 increases the number of displays when the angle of view of the photographing unit 20 is large, and decreases the number of displays when the angle of view is small. The number of displays of the object can be adjusted according to the setting of the angle of view of the photographing unit 20. Further, for example, the display control unit 35 decreases the number of displays of the object when the main body 10 is located outdoors, increases the number of displays of the object when it is located indoors, and can further increase the number of displays of the object when it is located inside the store selling the target object. In addition, the display control unit 35 can decrease the number of displays of the object when the weather is bad (rain, snow, strong wind, etc.) compared to when the weather is good (sunny, cloudy, etc.). In addition, the display control unit 35 can decrease the number of displays of the object when the weather is bad (rain, snow, strong wind, etc.) compared to when the weather is good (sunny, cloudy, etc.). 35 decreases the number of displays of the object when the main body 10 is located outdoors, increases the number of displays of the object when it is located indoors, and can further increase the number of displays of the object when it is located inside the store selling the target object. In addition, the display control unit 35 can decrease the number of displays of the object when the weather is bad (rain, snow, strong wind, etc.) compared to when the weather is good (sunny, cloudy, etc.). When the user enters the target store, the environment information detection unit 34 detects the environment around the main body 10. In addition, the display control unit 35 can decrease the number of displays of the object when the weather is bad (rain, snow, strong wind, etc.) compared to when the weather is good (sunny, cloudy, etc.). In addition, the display control unit 35 can decrease the number of displays of the object when the weather is bad (rain, snow, strong wind, etc.) compared to when the weather is good (sunny, cloudy, etc.).

[0030] When the user enters the target store, the environment information detection unit 34 detects the environment around the main body 10. Change the information from outside the store to inside the store. When the environmental information is changed to inside the store, the display control unit 35 , changes the display mode of the object. FIG. 5 is a diagram showing another example of the display content of the display unit 11 . In a state where the user is inside the store, as shown in FIG. 5, the display control unit 35 enlarges the display area 12 of the object preferred by the subscriber.

[0031] Also, the video acquisition unit 31 acquires the video captured by the imaging unit 20. The video analysis unit 32 extracts the object of the clothes from the acquired video. The calculation unit 33 obtains the preference matching degree of the object extracted by the video analysis unit 32 based on the preference data stored in the preference storage unit 36a . The calculation unit 33 calculates, for example, the score of the extracted object, and determines that the preference matching degree is high when it is higher than a predetermined threshold , and determines that the preference matching degree is low when it is lower than the predetermined threshold .

[0032] The display control unit 35 displays the video of the object on the display unit 11 in a predetermined display mode based on the preference matching degree calculated by the calculation unit 33 and the environmental information detected by the environmental information detection unit 34 . FIG. 5 is a diagram showing another example of the display content on the display unit 11 of the display device 100. As shown in FIG. 5, the display control unit 35 can display the objects P1, P2 , P3 extracted by the video analysis unit 32 on the display unit 11 respectively. Among these, for example, for the object P1 determined to have a high matching degree , it may be displayed enlarged compared to the other objects P2, P3 . Also, the display control unit 35, for example, represents the object P1 with the highest matching degree . Also, the display control unit 35, for example, represents the object P1 with the highest matching degree It may be displayed at the center of the display area 13. Further, the display control unit 35 determines that the degree of match is low For the object P3, for example, a hatching display may be performed on the whole to reduce visibility as a display mode. The predetermined display form of the object is not limited to the above and other display forms may be used.

[0033] In addition, for example, in the store, for the objects P1 and P2 determined to have a high degree of match, the display control unit 35 for the objects P1 and P2, when the distance between the product corresponding to the objects P1 and P2 and the main body 10 approaches, a display mode such as increasing the emphasis of the display as the distance approaches may be used as well. For example, the display control unit 35 analyzes the video in which the products corresponding to the objects P1 and P2 are photographed and determines whether the distance between the product and the main body 10 is approaching based on the change in the size of the photographed product within several tens of seconds.

[0034] In addition, the environmental information detection unit 34 may acquire product information about at least one of the price and inventory of the products corresponding to the objects P1 and P2 from the store, for example. In this case, the display control unit 35 can highlight the objects P1 and P2 according to the product information. The display control unit 35, for example, when the price of the product corresponding to the objects P1 and P2 is a discounted price may highlight the objects P1 and P2. Also, when the inventory of the products corresponding to the objects P1 and P2 is low, an emphasis display such as blinking the objects P1 and P2 may be performed so that it is possible to determine that the inventory is low. Note that the mode of the emphasis display is not limited to the above mode, and other modes are possible.

[0035] ​​​​​Also, when the display control unit 35 displays an object on the display unit 11, for example, when the main body unit 1 0 is located indoors, compared to the case where the main body unit 10 is not located indoors, the number of objects to be displayed can be increased. In this way, the display control unit 35 can adjust the number of objects to be displayed according to the environmental information.
