As an example of the terminal device 10, a tablet terminal, a smartphone, a photo panel, a mobile communication terminal such as a mobile phone or PHS (Personal Handyphone System), a slate terminal such as a PDA (Personal Digital Assistants), or the like can be used.

The communication unit 11 is realized by, for example, a NIC (Network Interface Card) when connected to the network N by a wire. When the communication unit 11 is wirelessly connected to the network N, the communication unit 11 is realized by, for example, a wireless communication module corresponding to a mobile phone line, a wireless LAN (Local Area Network), or the like. When the communication unit 11 is realized by a wireless communication module, the communication unit 11 is connected to the network N via a wireless base station (not shown). In other words, the communication unit 11 is a communication interface that is connected to the distribution device 100 via the network N in a wired or wireless manner and manages communication of information with the distribution device 100.

When any one or more of terminal information, post content inquiry, and request are input from the control unit 14, the communication unit 11 receives any one of the input terminal information, post content inquiry, and request. Or more are transmitted to the distribution apparatus 100 via the network N. Further, the communication unit 11 receives any one or more of a PUSH notification, a screen HTML (HyperText Markup Language), and a distribution image from the distribution apparatus 100 via the network N. The communication unit 11 outputs one or more of the received PUSH notification, the HTML of the screen, and the distribution image to the control unit 14.

The storage unit 12 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 12 stores information used for processing in the control unit 14.

The display operation unit 13 is a display device for displaying various information and an input device for receiving various operations from the user. For example, the display operation unit 13 is realized by a liquid crystal display or the like as a display device. Further, for example, the display operation unit 13 is realized by a touch panel or the like as an input device. That is, in the display operation unit 13, the display device and the input device are integrated. The display operation unit 13 outputs an operation input by the user to the control unit 14 as operation information. Note that the display operation unit 13 may separately provide a display device and an input device. The display operation unit 13 receives a reply to the message from the user, for example.

The control unit 14 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like executing a program stored in an internal storage device using the RAM as a work area. The control unit 14 may be realized by an integrated circuit such as ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array). The control unit 14 includes a notification unit 15 and a generation unit 16, and realizes or executes information processing functions and operations described below. Note that the internal configuration of the control unit 14 is not limited to the configuration illustrated in FIG. 1, and may be another configuration as long as information processing described later is performed.

The notification unit 15 transmits terminal information to the distribution device 100 via the communication unit 11 and the network N. The terminal information includes, for example, user information for identifying a user of the terminal device 10, a communication environment of the terminal device 10, a screen resolution of the display operation unit 13, and the like. Further, when receiving the PUSH notification from the distribution device 100, the notification unit 15 transmits a post content inquiry to the distribution device 100 via the communication unit 11 and the network N using, for example, HTTP (Hypertext Transfer Protocol). In addition, when the notification unit 15 receives the HTML of the screen from the distribution apparatus 100, the notification unit 15 includes identification information of an image desired to be downloaded in the HTML of the screen, an image size, an image format, and terminal information indicating the current communication environment. The request is transmitted to the distribution apparatus 100 and notified. In addition, the notification unit 15 outputs the HTML of the received screen to the generation unit 16.

Request, for example, calls a dedicated URI (Uniform Resource Identifier) with the GET method. The URI is expressed in a format such as “https: //hogehoge/picture.php? Photo_no = 1 & size = l & type = jpeg & connect = 3G”, for example. For example, “photo_no = 1” indicates an image number, “size = l” indicates an image size, “type = jpeg” indicates an image format, and “connect = 3G” indicates a network type. That is, it indicates the type of line to which the terminal device 10 is connected. Examples of the line type include third-generation mobile phone lines (3G), LTE, and wireless LAN.

Here, an example of the image size of the request is shown in FIG. FIG. 2 is an explanatory diagram illustrating an example of an image size parameter. As shown in FIG. 2, for example, the image size can be represented by parameters such as “size = 1”, “size = m”, and “size = s”. In the example of FIG. 2, for example, when the parameter is “size = 1”, an image having a width of 440 pixels is requested. For example, when the parameter is “size = m”, an image having a width of 200 pixels is requested. For example, if the parameter is “size = s”, an image of 60 × 60 pixels is requested. The image size parameter may be determined according to the screen resolution of the terminal device 10, the communication environment, the free capacity of the storage device, and the like. In addition, the terminal device 10 can request an image having a size corresponding to the screen resolution of the terminal device 10 to display the image without performing an enlargement / reduction process when the image is displayed. Can be reduced.

Returning to the description of FIG. 1, the generation unit 16 receives the HTML of the screen from the notification unit 15. Further, the generation unit 16 receives a distribution image corresponding to an image desired to be downloaded in the HTML of the screen from the distribution device 100 via the communication unit 11 and the network N. The generation unit 16 generates a screen to be displayed on the display operation unit 13 based on the HTML of the screen and the distribution image, and causes the display operation unit 13 to display the screen. That is, the generation unit 16 generates a display screen by combining each distribution image and text according to the HTML of the screen, and causes the display operation unit 13 to display the generated display screen. Note that the text included in the HTML of the screen generates a display screen with an optimal size according to, for example, different types of terminal devices 10. The generation unit 16 may display the generated display screen on the display unit instead of the display operation unit 13.

As illustrated in FIG. 1, the distribution device 100 includes a communication unit 110, a storage unit 120, and a control unit 130. In addition to the functional units shown in FIG. 1, the distribution apparatus 100 may have various functional units included in known computers, for example, functional units such as various input devices and audio output devices.

The communication unit 110 is realized by a NIC or the like, for example. The communication unit 110 is a communication interface that is connected to the terminal device 10 via the network N in a wired or wireless manner and manages communication of information with the terminal device 10. Upon receiving any one or more of terminal information, post content inquiry, and request from the terminal device 10, the communication unit 110 receives any one or more of the received terminal information, post content inquiry, and request. Output to the control unit 130. Further, when any one or more of the PUSH notification, the screen HTML, and the distribution image is input from the control unit 130, the communication unit 110 receives any one or more of the input PUSH notification, the screen HTML, and the distribution image. Is transmitted to the terminal device 10 via the network N.

The storage unit 120 is realized by, for example, a semiconductor memory device such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 120 includes a message storage unit 121. The message storage unit 121 is an image storage unit that stores an image in association with a message. In addition, the storage unit 120 stores information used for processing in the control unit 130.

The message storage unit 121 stores a message and an image posted to the SNS by the user in association with, for example, a message ID (IDentifier) and a poster ID. FIG. 3 is an explanatory diagram illustrating an example of a message storage unit. As shown in FIG. 3, the message storage unit 121 includes items such as “message ID”, “contributor ID”, “message”, and “image 1” to “image 3”. When a certain user posts a message, the message storage unit 121 generates one record for each message.

“Message ID” identifies a message, for example, a serial number for each group with SNS. “Contributor ID” identifies the user who posted the message. “Message” indicates a posted message. “Image 1” to “Image 3” indicate, for example, a photograph image taken by the terminal device 10, a user profile image, a pictographic image, and the like. Note that “image 1” to “image 3” increase or decrease according to the number of images included in one message.

Returning to the description of FIG. 1, the control unit 130 is realized by, for example, a CPU or MPU executing a program stored in an internal storage device using the RAM as a work area. The control unit 130 may be realized by an integrated circuit such as ASIC or FPGA, for example. The control unit 130 includes a reception unit 131, a specification unit 132, a conversion unit 133, and a distribution unit 134, and realizes or executes functions and operations of information processing described below. Note that the internal configuration of the control unit 130 is not limited to the configuration illustrated in FIG. 1, and may be another configuration as long as the information processing described below is performed.

When the terminal information is input from the communication unit 110, the reception unit 131 registers the user indicated by the user information based on the user information included in the terminal information. The reception unit 131 may register the user so that the entire SNS can be posted and viewed, or may be registered so that only users belonging to a group or organization can post and browse. .

Also, the accepting unit 131 receives and accepts messages posted from each user via the communication unit 110. For example, when a message is posted from a registered user, the reception unit 131 associates the posted message, the image accompanying the message, and the poster ID that is the ID of the posted user with the message ID. It is stored in the message storage unit 121.

Here, an example of a screen when each user posts a message will be described with reference to FIG. FIG. 4 is an explanatory diagram illustrating an example of a posting screen. As shown in FIG. 4, the posting screen 20 displays, for example, an image 21 of a photo to be posted, a photo selection button 22, a photo deletion button 23, a message 24, a pictograph 25, and a posting button 26. For example, the user accesses the distribution device 100 and causes the terminal device 10 to display the posting screen 20. For example, when posting a photo, the user presses the photo selection button 22 to display options and selects a photo to be posted. Further, for example, when deleting the selected photo, the user presses the photo delete button 23 to delete the selected photo. In addition, the user inputs, for example, a message 24 and pictograph 25 to be displayed together with a photograph to be posted using a keyboard (not shown) of the display operation unit 13. When the posting button 26 is pressed by the user, the terminal device 10 transmits the input message and image to the distribution device 100 via the network N. The distribution apparatus 100 accepts the received message and image as a post.

When the accepting unit 131 stores the posted message in the message storage unit 121, for example, the receiving unit 131 sends a PUSH notification indicating that the message has been posted to the terminal device 10 of another user belonging to the same group. Send through. The PUSH notification includes, for example, a path for each image in addition to a message path.

Also, the accepting unit 131 receives an inquiry about the posted content transmitted from the terminal device 10 in response to the PUSH notification via the communication unit 110. When receiving the post content inquiry, the accepting unit 131 generates HTML of a screen for displaying the post content. The accepting unit 131 transmits the generated HTML of the screen to the terminal device 10 via the communication unit 110.

Also, the accepting unit 131 receives and accepts a request based on the HTML of the screen from the terminal device 10 via the communication unit 110. The accepting unit 131 outputs the accepted request to the specifying unit 132. Here, the request is transmitted from the terminal device 10 for each image in the HTML of the screen. That is, the reception unit 131 receives a request from the terminal device 10 for each image with respect to one or more images displayed on the display operation unit 13 of the terminal device 10.

When the request is input from the receiving unit 131, the specifying unit 132 refers to the message storage unit 121 based on the image identification information included in the request and specifies an image corresponding to the image identification information. The identification unit 132 reads the identified image from the message storage unit 121 and outputs the image together with the request to the conversion unit 133. When requests are sequentially transmitted from the terminal device 10, the specifying unit 132 specifies an image for each request.

When the specified image and request are input from the specifying unit 132, the conversion unit 133 determines the specified image based on the image size, the image format, and the terminal information included in the request according to the terminal device 10 that transmitted the request. Convert to an image. For example, when the specified image is an image of 1600 × 1200 pixels and the image size parameter is designated as “size = 1”, that is, a width of 440 pixels, the conversion unit 133 fixes the aspect ratio, for example. Can be converted into an image of 440 × 330 pixels. The conversion unit 133 outputs the converted image to the distribution unit 134 in association with the request. Note that the conversion unit 133 may determine the image size after conversion in accordance with the screen resolution of the display operation unit 13 included in the terminal information. Further, the conversion unit 133 may convert the image to be converted by changing the aspect ratio so as to match the shape of the screen of the display operation unit 13.

For example, when the image format of the specified image is a JPEG (Joint Photographic Experts Group) format and the image format included in the request is a GIF (Graphics Interchange Format) format, the conversion unit 133 converts the JPEG format. Convert to GIF format. The conversion unit 133 can use various file formats such as PNG (Portable Network Graphics) format and BMP (Bitmap Image) format as well as JPEG format and GIF format as the format of image files to be converted to each other. . The conversion unit 133 may convert not only a still image but also a moving image. For example, the conversion unit 133 can convert an animation GIF format and a Motion JPEG format to each other. In addition, the conversion unit 133 may use, for example, MPEG (Moving Picture Experts Group) -1, MPEG-2, MPEG-4 AVC / H. H.264 or the like may be used.

Further, the conversion unit 133 may convert the image into an image according to the current communication environment of the terminal device 10 based on the terminal information of the terminal device 10 included in the request, for example. For example, in the case of an LTE or 3G line which is a mobile phone line as a communication environment, the conversion unit 133 can reduce the image data amount by increasing the compression rate of the JPEG format, for example. For example, the conversion unit 133 may set the image size to be smaller than the image size included in the request.

When the converted image and the request are input from the conversion unit 133, the distribution unit 134 sets the converted image as a distribution image to the corresponding terminal device 10 based on the terminal information in the request together with the identification information of the image. Distribution is performed via the communication unit 110.

Here, display examples of screens of messages downloaded by the terminal device 10 from the distribution device 100 will be described with reference to FIGS. FIG. 5 is an explanatory diagram illustrating an example of a display screen on the terminal device. As illustrated in FIG. 5, the terminal device 10 downloads a message corresponding to the request from the terminal device 10 and an accompanying image from the distribution device 100 and displays the message on the display operation unit 13. That is, the picture image 21, the pictograph 25, and the profile image 27 displayed on the display operation unit 13 are converted by the conversion unit 133 of the distribution device 100 in response to the request, and the display operation unit of the terminal device 10 is displayed according to the HTML of the screen. 13 is displayed. For this reason, the screen displayed on the display operation unit 13 is a display suitable for the terminal device 10.

On the other hand, FIGS. 6 and 7 show display examples when the photographic image 21, pictograph 25 and profile image 27 are not converted. FIG. 6 is an explanatory diagram illustrating an example of a display screen when image conversion is not performed. FIG. 7 is an explanatory diagram illustrating another example of the display screen when image conversion is not performed. In the example of FIG. 6, the photographic image 21 displayed on the terminal device 31 is larger than the display unit of the terminal device 31, and only a part of the photographic image 21 is displayed. Further, the profile image 27, the message 24, and the pictogram 25 are in a state in which their arrangement and size and the balance with the photographic image 21 are poor and the display is cut off. In the example of FIG. 7, the photograph image 21 displayed on the terminal device 32 is smaller than the display unit of the terminal device 32 and is displayed in the center of the display unit. Further, the profile image 27, the message 24, and the pictograph 25 are displayed in a large size with respect to the photo image 21, and the screen is unbalanced as in the case of FIG.

Next, the operation of the distribution system 1 of the embodiment will be described. In addition, in the following description, it demonstrates including the operation | movement in which the user of the terminal device 10 registers the terminal information of the terminal device 10 with respect to a group with SNS.

The notification unit 15 of the terminal device 10 transmits terminal information to the distribution device 100 via the communication unit 11 in accordance with an instruction from the user of the terminal device 10 (step S1). The receiving unit 131 of the distribution apparatus 100 receives the terminal information via the communication unit 110, and registers the user indicated by the user information in the group based on the user information included in the terminal information (Step S2).

In the above-mentioned SNS, a message including an image is posted from another user belonging to a certain group (step S3). The accepting unit 131 receives and accepts a message posted from the other user via the communication unit 110 (step S4). The accepting unit 131 stores a message including an image posted by the other user in the message storage unit 121 (step S5). When receiving the posted message in the message storage unit 121, the reception unit 131 transmits a PUSH notification to the user terminal device 10 via the communication unit 110 (step S6).

When the notification unit 15 of the terminal device 10 receives the PUSH notification from the distribution device 100 via the communication unit 11 (step S7), the notification unit 15 transmits a post content inquiry to the distribution device 100 via the communication unit 11 (step S8). . Receiving unit 131 of distribution device 100 receives the inquiry about the posted content via communication unit 110 (step S9), and generates HTML of a screen for displaying the posted content (step S10). The accepting unit 131 transmits the generated HTML of the screen to the terminal device 10 via the communication unit 110 (step S11).

The notification unit 15 of the terminal device 10 receives the HTML of the screen from the distribution device 100 via the communication unit 11 (step S12). The notification unit 15 generates a request including identification information of an image desired to be downloaded in HTML of the received screen, an image size, an image format, and terminal information indicating the current communication environment (step S13). The notification unit 15 transmits the generated request to the distribution device 100 via the communication unit 11 (step S14). In addition, the notification unit 15 outputs the HTML of the received screen to the generation unit 16.

The receiving unit 131 of the distribution apparatus 100 receives a request based on the HTML of the screen from the terminal device 10 via the communication unit 110 (step S15). The accepting unit 131 accepts the received request and outputs the request to the specifying unit 132. When a request is input from the receiving unit 131, the specifying unit 132 refers to the message storage unit 121 based on the image identification information included in the request, and specifies an image corresponding to the image identification information (step S16). . The identification unit 132 reads the identified image from the message storage unit 121 and outputs the image together with the request to the conversion unit 133.

When the specified image and request are input from the specifying unit 132, the conversion unit 133 determines the specified image based on the image size, the image format, and the terminal information included in the request according to the terminal device 10 that transmitted the request. The image is converted (step S17). The conversion unit 133 outputs the converted image to the distribution unit 134 in association with the request. When the converted image and the request are input from the conversion unit 133, the distribution unit 134 sets the converted image as a distribution image to the terminal device 10 that has transmitted the request via the communication unit 110 together with the identification information of the image. (Step S18).

The generation unit 16 of the terminal device 10 receives the distribution image from the distribution device 100 via the communication unit 11 (step S19). Note that the terminal device 10 sequentially generates and transmits requests for images in the HTML of the screen. Further, the distribution device 100 distributes the image converted in response to the request received from the terminal device 10. That is, the distribution system 1 repeats steps S13 to S19 for all images that require conversion in the HTML of the screen.

The generation unit 16 of the terminal device 10 generates a display screen to be displayed on the display operation unit 13 based on the HTML of the screen and the distribution image (step S20). The generation unit 16 causes the display operation unit 13 to display the generated display screen (step S21). Thereby, since the distribution system 1 converts the image by the distribution device 100 and distributes it in response to the request from the terminal device 10, it is possible to display an appropriate content without distorting the display on the terminal device 10. . In addition, since the distribution system 1 converts and distributes the image with the distribution device 100 according to the communication status of the terminal device 10, the user can refer to the image without worrying about the communication amount. Furthermore, since the terminal device 10 can automatically acquire a message including an image when receiving the push notification, for example, the generated display screen is displayed on the lock screen of the terminal device 10 so that the user can easily post the posted content. It can be grasped.

Thus, the distribution apparatus 100 receives from the terminal apparatus 10 a request including the identification information of the image desired to be downloaded, the image size, the image format, and the terminal information of the terminal apparatus 10. Further, the distribution apparatus 100 refers to the image storage unit in which the image is stored, and specifies an image corresponding to the identification information of the received request image. Further, the distribution apparatus 100 converts the identified image into an image according to the request based on the image size, the image format, and the terminal information, and distributes the converted image to the terminal apparatus 10. As a result, the user can refer to the image without worrying about the traffic.

Further, the distribution apparatus 100 accepts a request from the terminal apparatus 10 for each image regarding one or more images displayed on the screen of the terminal apparatus 10. As a result, it is possible to perform conversion suitable for display on the terminal device 10 for each image.

Also, the distribution device 100 receives the communication environment of the terminal device 10 as terminal information, and converts the identified image into an image according to the communication environment. As a result, an image corresponding to the communication environment of the terminal device 10 can be distributed.

Also, the distribution device 100 receives the screen resolution of the display unit of the terminal device 10 as terminal information, and converts the identified image into an image corresponding to the screen resolution.
