  The media controller 100e reads various data and programs from a recording medium including a flash memory, a CD (Compact Disc), a DVD (Digital Versatile Disc), a Blu-ray Disc (registered trademark), and the like.

  The wireless LAN card 100f wirelessly communicates various information with various devices connected via a communication network (not shown). The operation button 100i inputs a signal or information corresponding to a user operation.

  The video card 100g draws (that is, renders) an image based on the digital signal output from the CPU 100a, and outputs an image signal representing the drawn image. The LCD 100h displays an image according to the image signal output from the video card 100g. The image display device 100 may include a PDP (Plasma Display Panel) or an EL (Electroluminescence) display instead of the LCD 100h. The speaker 100j outputs sound based on the signal output from the CPU 100a. The microphone 100l collects sound and inputs an electric signal representing the collected sound to the CPU 100a.

  First, a process for displaying a captured image (hereinafter referred to as a message image) in which the image display apparatus 100 captures a message is displayed while a slide show is being executed.

  The CPU 100a functions as the information input unit 103 as shown in FIG. 4 by executing the message storing process as shown in FIG. 3 using the hardware of FIG. Further, the CPU 100a functions as the imaging unit 102 in FIG. 4 by cooperating with the CMOS sensor 100k in FIG. 2, and functions as the sound collecting unit 101 by cooperating with the microphone 100l, and the hard disk 100d or the media controller 100e. By cooperating with a recording medium on / from which information is read and written, it functions as the temporary storage unit 104.

  The temporary storage unit 104 stores a message table as shown in FIG. In this message table, information (hereinafter referred to as a destination user ID) for identifying a user designated as a partner to whom the message is heard (hereinafter referred to as a message destination), and a state in which the user who has designated the user speaks the message Is associated with information (hereinafter referred to as message image information) representing a captured image (that is, message image information) and information (hereinafter referred to as message voice information) representing a voice conveying the message (hereinafter referred to as message voice information). Has been saved.

  When the CPU 100a receives a signal for instructing to start storing the message by the operation button 100i operated by the user, the CPU 100a starts the message storing process of FIG. 3 according to the signal. When the message storing process is started, the information input unit 103 in FIG. 4 inputs the destination user ID from the operation button 100i operated by the user (step S01). Next, the imaging unit 102 starts imaging a user who speaks a message, and starts outputting image information representing the message image of the user (that is, message image information). For this reason, the imaging unit 102 that outputs image information to the information input unit 103 is referred to as an image output unit OT.

  Next, the information input unit 103 inputs image information output from the imaging unit 102 (step S02). Furthermore, the voice collection unit 101 collects the message voice of the user and starts outputting voice information representing the collected message voice. Further, the information input unit 103 inputs voice information output from the voice collection unit 101 (step S03). Thereafter, when the imaging unit 102 finishes imaging, the audio collection unit 101 ends the collection of audio. Next, the information input unit 103 stores the input destination user ID, message image information, and message voice information in the message table of FIG. 5 in association with each other (step S04), and then performs message storage processing. End execution.

  When the execution of the message storage process is completed, the CPU 100a functions as the user detection unit 105 as shown in FIG. 4 by executing the destination user detection process as shown in FIG. 6 using the hardware of FIG. . The CPU 100a functions as the user information storage unit 106 by cooperating with a recording medium in which information is read and written by the hard disk 100d or the media controller 100e.

  The user information storage unit 106 stores a user table as shown in FIG. In this user table, a user ID for identifying a user and feature information representing the feature of the user are stored in association with each other. The characteristics of the user are specified by executing a known analysis process on the image representing the user. For example, the color of the skin, the color of the hair, the position of the eyes, nose, or mouth relative to the face, the size Or represented by information representing the shape.

  When the destination user detection process in FIG. 6 is started, the user detection unit 105 in FIG. 4 acquires a destination user ID from the information input unit 103 (step S11). Next, the user detection unit 105 acquires feature information stored in association with the same user ID as the input destination user ID from the user table in FIG. 7 (step S12). Thereafter, the imaging unit 102 starts imaging, and the information input unit 103 inputs image information representing a captured image (hereinafter referred to as captured image information) from the imaging unit 102 (step S13).

  Next, the user detection unit 105 performs a known user area detection process and a known user identification process on the captured image represented by the input captured image information (step S14). Next, the user detection unit 105 determines whether or not the destination user identified by the destination user ID input in step S01 has been detected from the captured image represented by the information input in step S13 (step S13). S15). Specifically, the user detection unit 105 determines whether or not an area in which the user is represented (hereinafter referred to as a user area) is detected from the captured image by executing a known user area detection process. At this time, if the user detection unit 105 determines that the user area has not been detected, the user detection unit 105 determines that the destination user has not been detected. On the other hand, when the user detection unit 105 determines that the user area is detected from the captured image, the user detection unit 105 analyzes the partial image in the detected user area to acquire feature information representing the feature of the user. After that, the user detection unit 105 acquires a user ID associated with the feature information acquired from the partial image of the user area from the user table of FIG. 7, and the acquired user ID is the destination user ID input in step S01. To determine whether or not they match. At this time, if the user detection unit 105 determines that the user IDs do not match, it determines that the destination user has not been detected from the captured image. In contrast, if the user detection unit 105 determines that the user IDs match, the user detection unit 105 determines that the destination user is detected from the captured image.

  In step S15 of FIG. 6, when the user detection unit 105 determines that the destination user is not detected from the captured image (step S15; No), the process returns to step S13 and repeats the above processing. On the other hand, when the user detection unit 105 determines that the destination user is detected from the captured image (step S15; Yes), after reporting that the destination user is detected to the determination unit 107 in FIG. S16) Returning to step S13, the above processing is repeated. Specifically, the user detection unit 105 may report the detection of the destination user to the determination unit 107 using a flag in the shared memory that is used jointly with the determination unit 107, or may use a pipeline.

  When the execution of the message storage process is completed, the CPU 100a in FIG. 2 starts to display the image represented by the image information according to the output destination (that is, the image output unit OT) that has output the image information ( Hereinafter, a process for determining the display start timing) is selected, and the selected process is executed. Here, the CPU 100a executes the first determination process as shown in FIG. 8 that determines the display start timing of the message image output from the imaging unit 102 using the hardware of FIG. Thereby, the CPU 100a functions as the determination unit 107 as shown in FIG.

  When the first determination process in FIG. 8 is started, the determination unit 107 in FIG. 4 determines whether or not the detection of the destination user is reported from the user detection unit 105 (step S21). At this time, if the determination unit 107 determines that the detection of the destination user has not been reported (step S21; No), a signal (hereinafter, referred to as an instruction to start reading the message from the operation button 100i operated by the user). It is determined whether or not a message reading start instruction signal has been acquired (step S22). At this time, if the determination unit 107 determines that the message reading start instruction signal has not been acquired (step S22; No), the determination unit 107 returns to step S21 and repeats the above processing.

  If the determination unit 107 determines in step S21 that the detection of the destination user has been reported (step S21; Yes), or if it is determined in step S22 that the message reading start instruction signal has been acquired (step S22; Yes), for example, the system date and time is acquired from the OS (Operating System), and the timing within the predetermined time from the acquired system date and time is set as the display start timing. (Referred to as display timing) (step S23).

  Information representing the predetermined time used in step S23 is stored in advance in the hard disk 100d in FIG. In the present embodiment, the predetermined time used in step S23 is a predetermined time for displaying the message image. For example, the predetermined time is “1” seconds. However, the predetermined time is not limited thereto. One skilled in the art can determine more suitable values by experimentation.

  Next, the determination unit 107 determines whether or not a signal for instructing to end the reading of the message (hereinafter referred to as a message reading end instruction signal) has been acquired from the operation button 100i operated by the user (Step S100). S24). At this time, when determining unit 107 determines that the message reading end instruction signal has not been acquired (step S24; No), it acquires the system date and time again. Next, the determination unit 107 determines whether or not the display timing already determined in step S23 or the subsequent step S26 has arrived based on the system date and time (step S25). At this time, when the determination unit 107 determines that the display timing has not arrived (step S25; No), the determination unit 107 returns to step S24 and repeats the above processing. On the other hand, when the determination unit 107 determines that the display timing has arrived (step S25; Yes), the display timing is set to a timing after a predetermined intermittent time (or before the intermittent time) from the system date and time (step S25). S26) Returning to step S24, the above processing is repeated.

  Information indicating the intermittent time used in step S25 is stored in advance in the hard disk 100d in FIG. In the present embodiment, the intermittent time used in step S23 is a predetermined time for a message, and is described as being, for example, “10” seconds, but is not limited thereto, and those skilled in the art A more suitable value can be determined by experiment.

  If the determination unit 107 determines in step S24 that the message reading end instruction signal has been acquired (step S24; Yes), the information stored in the message table in FIG. 5 is deleted, and then the first determination process ends.

  When the image display apparatus 100 is activated (that is, when the power is turned on), the CPU 100a in FIG. 2 executes an image display process as shown in FIG. Functions as the unit 110 and the audio output unit 111. The CPU 100a functions as the image information storage unit 108 by cooperating with a recording medium in which information is read and written by the hard disk 100d or the media controller 100e.

  When the image display process of FIG. 9 is started, the information acquisition unit 109 of FIG. 4 acquires a plurality of pieces of image information from the image information storage unit 108 (step S31). Next, the information acquisition unit 109 determines the images respectively represented by the acquired plurality of pieces of image information as images to be slide show (that is, slide show targets) (step S32).

  Thereafter, the display unit 110 acquires the system date and time, and determines whether or not the display timing determined in step S23 or step S26 of FIG. 8 has arrived (step S33). At this time, if the display unit 110 determines that the display timing has not arrived (step S33; No), the display unit 110 randomly selects one image from the images targeted for the slide show and displays the selected image ( That is, a slide show is performed) (step S34). Thereafter, the above process is repeated from step S33.

  In step S33, when the display unit 110 determines that the display timing has arrived (step S33; Yes), the message image information stored in the message table of FIG. 5 is read, and the message image represented by the read information (that is, the message image) , The captured image) is displayed on the display unit 110 (step S35). Also, the voice output unit 111 in FIG. 4 reads the message voice information stored in the message table in FIG. 5 in association with the image information (that is, message image information) of the message image, and the message image is displayed. Meanwhile, the message voice represented by the read information is output (step S36). Then, it returns to step S33 and the said process is repeated.

  According to these configurations, when a slide show that sequentially displays images represented by a plurality of pieces of image information stored in the image information storage unit 108 is executed, a captured image that is different from the image to be displayed is displayed on the captured image. Displayed intermittently from the display start timing determined according to the output source (that is, the image output unit OT in FIG. 4). For this reason, it is possible to prevent the display of an image from becoming monotonous than in the past.

  According to these configurations, the captured image is displayed within a predetermined time after the destination user designated as the display destination of the captured image is detected from the image captured in the direction in which the image is displayed. For this reason, the captured image can be reliably displayed to the destination user designated as the display destination. In addition, when a slide show is performed, a captured image designated with the user as a display destination is displayed for a user who is viewing the slide show, so that the user is given freshness and impression and the image display is monotonous. Can be prevented.

  Furthermore, according to these configurations, when a destination user designated as a partner who hears a message is detected from an image obtained by capturing the direction in which the image is displayed, the message is output and captured when the message is collected. The displayed image is displayed. For this reason, it is possible not only to make the voice specified to the user designated as the other party to listen to the message more reliable than before, but also to display the image captured at the time of collecting the message to the user. If the user is positioned in the direction in which the image is displayed, a message addressed to the user is output, and an image captured during collection of the message may be displayed. Can be given to the user.

  In the first determination process of the present embodiment, the determination unit 107 may lengthen the intermittent time every time the display timing arrives (that is, every time a captured image is displayed). A user who has heard a message often loses interest in the message. However, if the user cannot remember a message or forgets it once, the user may want to listen to the message again. Many. For this reason, according to this configuration, the message output frequency and the captured image display frequency decrease as the message output count and the captured image display count increase, so that the captured image that the user has already lost interest in can be displayed. It is possible to prevent the user from remembering or forgetting the message while preventing the output of the message.

  Note that when the message storage process is finished, the image display apparatus 100 blinks an LED (Light Emitting Diode) lamp (not shown) until a message reading end instruction signal is input (that is, there is a message (that is, The message voice information may be stored).

  Next, processing executed when the image display apparatus 100 displays an image representing a user's schedule (hereinafter referred to as a scheduled image) will be described.

  The CPU 100a functions as a schedule information storage unit 112 as shown in FIG. 4 by cooperating with a recording medium in which information is read and written by the hard disk 100d or the media controller 100e in FIG. The schedule information storage unit 112 stores a schedule table as shown in FIG. The schedule table includes a user ID (hereinafter referred to as a schedule execution user ID) of a user who executes the schedule (hereinafter referred to as a schedule execution user ID), schedule information indicating the schedule, and information (hereinafter referred to as start date and time of the schedule). , Start date / time information) and information indicating the end date / time of the schedule (hereinafter referred to as end date / time information) are stored in association with each other.

  The CPU 100a executes a schedule image generation process (not shown) that generates an image representing a schedule (hereinafter referred to as a schedule image) represented by schedule information stored in the schedule table of FIG. It functions as the scheduled image generation unit 113. When the scheduled image generation process is started, the scheduled image generation unit 113 obtains the start time from the acquired system date and time to the date and time after the first time from the schedule table in FIG. 10 after acquiring the system date and time. The start time information, the schedule information associated with the start time information, and the schedule execution user ID are searched.

  In the present embodiment, the information representing the first time is stored in advance in the hard disk 100d of FIG. 2 and the like, and the first time is described as being “30”. However, the present invention is not limited to this. Rather, those skilled in the art can determine the optimum value by experimentation. The first time may be specified by the user.

  Thereafter, the schedule image generation unit 113 generates a schedule image representing the schedule represented by the searched schedule information, the image information representing the generated schedule image, the searched schedule execution user ID, and the schedule After the scheduled start time information indicating the start time is output to the information input unit 103 in FIG. 4, the execution of the scheduled image generation process (not shown) is terminated. For this reason, the scheduled image generation unit 113 is referred to as an image output unit OT, similar to the sound collection unit 101 and the imaging unit 102.

  Thereafter, the information input unit 103 inputs the image information of the scheduled image output from the scheduled image generation unit 113, the scheduled execution user ID, and the scheduled start time information. Next, the information input unit 103 temporarily stores the input image information of the scheduled image in the temporary storage unit 104 of FIG. 4, and stores the scheduled execution user ID and the scheduled start time information to the user detection unit 105. Output. The user detection unit 105 that inputs these pieces of information executes a scheduled execution user detection process as shown in FIG. 11 for detecting a scheduled execution user from the captured image captured by the imaging unit 102.

  When the scheduled execution user detection process in FIG. 11 is started, the user detection unit 105 acquires the scheduled execution user ID and the start date / time information from the information input unit 103 (step S41). Next, the user detection unit 105 acquires feature information associated with the same user ID as the scheduled execution user ID from the user table of FIG. 7 as in step S12 of FIG. 6 (step S42). Thereafter, the user detection unit 105 acquires the system date and time, and determines whether or not the scheduled start time represented by the start date and time information has arrived based on the acquired system date and time (step S43).

  In step S43, when the user detection unit 105 determines that the scheduled start time has not arrived based on the system date and time (step S43; No), the user execution unit 105 uses the scheduled execution user ID acquired in step S41 to perform FIG. Steps S13 to S16 are executed to execute a process for detecting the scheduled execution user from the captured image captured by the imaging unit 102 (from Step S44 to Step S47), and then return to Step S43 and return to Step S43. Repeat the process.

  In step S43, when determining that the scheduled start time has elapsed based on the system date and time (step S43; Yes), the user detecting unit 105 ends the execution of the scheduled execution user detection process.

  Further, the information input unit 103 outputs the scheduled start time information to the determination unit 107. Next, the determination unit 107 in FIG. 4 performs a second determination process as illustrated in FIG. 12 that determines the display start timing of the planned image output from the planned image generation unit 113.

  When the second determination process in FIG. 12 is started, the determination unit 107 in FIG. 4 determines whether or not the detection of the scheduled execution user is reported from the user detection unit 105, similarly to step S21 in FIG. 8 (step S51). ). At this time, when determining that the detection of the scheduled execution user has not been reported (step S51; No), the determination unit 107 acquires the system date and time. Next, the determination unit 107 determines whether or not the start date and time represented by the start date and time information output from the information input unit 103 has arrived based on the acquired system date and time (step S52). At this time, if it is determined that the start date / time has not elapsed (step S52; No), the above processing is repeated from step S51. On the other hand, if it is determined that the start date has passed (step S52; Yes), the execution of the second determination process is terminated.

  In step S51, when the determination unit 107 determines that the detection of the scheduled execution user has been reported (step S51; Yes), the timing within the predetermined time from the system date and time is displayed as the display start timing as in step S23 of FIG. The display start timing is set as the next display timing of the scheduled image (step S53).

  Information indicating the predetermined time used in step S53 is stored in advance in the hard disk 100d in FIG. In the present embodiment, the predetermined time used in step S53 is a predetermined time for displaying the scheduled image, and for example, is described as being “1” seconds, but is not limited thereto. One skilled in the art can determine more suitable values by experimentation.

  After step S53, the determination unit 107 determines whether or not the start date / time has arrived, similarly to step S52 (step S54). At this time, when the determination unit 107 determines that the scheduled start date / time has not arrived (step S54; No), the determination unit 107 performs the same determination as step S25 in FIG. 8 to determine whether the display timing has arrived. A determination is made (step S55). At this time, when the determination unit 107 determines that the display timing has not come (step S55; No), the determination unit 107 returns to step S54 and repeats the above processing. On the other hand, when determining that the display timing has arrived (step S55; Yes), the determination unit 107 decrements the value of the variable storing the value representing the intermittent time by a predetermined decrement value for the scheduled image. (Step S56a). This is to increase the display frequency of the scheduled image as time passes.

  Note that the value of the variable storing the value representing the intermittent time is initialized with a value representing the predetermined initial value of the intermittent time for the scheduled image at the start of the second determination process. Information indicating the initial value of the intermittent time for the scheduled image and information indicating the decrement value for the scheduled image are stored, for example, in the hard disk 100d in FIG. In this embodiment, the initial value of the intermittent time for the scheduled image is “7”, and the decrement value for the scheduled image is “1”. However, the present invention is not limited to this. The trader can determine the optimum value by experiment.

  Thereafter, the determination unit 107 repeats the above-described processing from step S54 after the display timing is set to the timing after the intermittent time (or before the intermittent time) represented by the value of the variable from the system date and time (step S56b).

  When determining that the scheduled start date / time has arrived based on the system date / time in step S54 (step S54; Yes), the determining unit 107 deletes the image information of the scheduled image stored in the temporary storage unit 104 of FIG. The second determination process is finished later.

  According to these configurations, when a user who executes the schedule is detected from an image obtained by capturing the direction in which the schedule image is displayed between the first hour before the start date and time of the schedule and the start date and time, The scheduled image is displayed.

The information representing the predetermined number of times is stored in advance in the hard disk 100d of FIG. 2 and the like, and in the present embodiment, for example, it is described as “10” times. However, the number of times is not limited to this. Can determine a more suitable value by experiment. Note that the variable storing the value representing the number of times of display is initialized with the value “0” at the start of the third determination process.

  In step S62, when the determination unit 107 determines that the interphone image or the security image is not displayed a predetermined number of times (step S62; No), the determination unit 107 determines whether or not the display timing has arrived, as in step S25 of FIG. (Step S63). At this time, if the determination unit 107 determines that the display timing has not arrived (step S63; No), the determination unit 107 returns to step S62 and repeats the above processing. On the other hand, when determining that the display timing has arrived (step S63; Yes), the determination unit 107 increments the value of the variable storing the value representing the intermittent time by a predetermined increment value (step S64a). ). This is to reduce the display frequency of the scheduled image as time passes.

  Note that the value of the variable storing the value representing the intermittent time used in step S64a is initially set to a value representing the initial value of the intermittent time for a predetermined interphone image and security image at the start of the third determination process. It becomes. The information indicating the initial value of the intermittent time for the interphone image and the security image and the information indicating the increment value for the interphone image and the security image are stored in, for example, the hard disk 100d in FIG. In this embodiment, the initial value of the intermittent time for the interphone image and the security image is “20” seconds, and the decrement value for the scheduled image is “10” seconds. However, the present invention is not limited to this. Rather, those skilled in the art can determine the optimum value by experiment.

  Thereafter, the determination unit 107 sets the display timing to the timing after the intermittent time (or before the intermittent time) represented by the value of the variable from the system date and time (step S64b), and then returns to step S62 and repeats the above processing.

  In step S62, when determining unit 107 determines that the interphone image or security image has been displayed a predetermined number of times (step S62; Yes), the image information of the interphone image or security image stored in temporary storage unit 104 in FIG. 14 is deleted. After that, the third determination process is terminated.

  The server 300 stores an upload image table as shown in FIG. The upload image table includes information for identifying an upload image (hereinafter referred to as upload image ID), image information of the upload image (hereinafter referred to as upload image information), and a user ID of the user who uploaded the upload image (hereinafter referred to as upload image ID). , Referred to as upload user ID), point number information representing the number of points of the user, and evaluation information representing the evaluation of the uploaded image are stored in association with each other.

  Note that the number of user points refers to, for example, the number of points that can be exchanged for services or products. The server 300 may store information representing the balance of electronic money instead of the number of points. The evaluation of the uploaded image is expressed by the popularity of the uploaded image. In the present embodiment, it is assumed that the popularity of an uploaded image is higher as the number of times the user has viewed the uploaded image is higher.

  An image display apparatus 100 according to the third embodiment includes an imaging unit 102, an information input unit 103, a temporary storage unit 104, a user detection unit 105, a determination unit 107, an image information storage unit 108, an information acquisition unit 109, as illustrated in FIG. A display unit 110 and a reception unit 114 are included. Since these functional units are the same as the functional units described in the first and second embodiments, redundant description will be omitted.

  The CPU 100a of the image display device 100 functions as the transmission unit 115 in FIG. 18 by cooperating with the wireless LAN card 100f in FIG. When the transmission unit 115 transmits a request for transmitting an upload image to the server 300, the reception unit 114 receives the image information of the upload image and the upload image ID of the upload image from the server 300. Thereafter, the receiving unit 114 acquires the system date and time, and uses the acquired system date and time as the reception date and time. Next, the reception unit 114 sets the upload image represented by the received image information as the received image, and sets the upload image ID as information for identifying the received image (hereinafter, image ID of the received image).

  The temporary storage unit 104 in FIG. 18 stores a received image table as shown in FIG. In the received image table, an image ID of the received image (hereinafter referred to as a received image ID), image information of the received image (hereinafter referred to as received image information), and an image captured by the imaging unit 102 while the received image is displayed. Information indicating the number of times the user has been detected from the image (hereinafter referred to as the number of user detections) is stored in association with each other.

  The information input unit 103 receives image information (hereinafter referred to as reception image information) from the reception unit 114, an image ID of the reception image (hereinafter referred to as reception image ID), and information indicating the reception date and time (hereinafter referred to as reception date and time). Information). For this reason, as in the second embodiment, the reception unit 114 is referred to as an image output unit OT. FIG. 18 shows only the receiving unit 114 called the image output unit OT, but the image display device 100 includes another functional unit called the image output unit OT.

  Next, the information input unit 103 temporarily stores the input received image information, received image ID, and information indicating that the number of detections is “0” in the received image table of FIG. The reception date / time information is output to the determination unit 107.

  Next, the determination unit 107 in FIG. 18 performs a fourth determination process as illustrated in FIG. 20 that determines the display start timing of the received image output from the information input unit 103.

  When the fourth determination process of FIG. 20 is started, the determination unit 107 of FIG. 18 is within a predetermined time from the reception date and time represented by the reception date and time information output from the information input unit 103, as in step S61 of FIG. Is the display start timing, and this display start timing is the next display timing of the received image (step S71).

  Information indicating the predetermined time used in step S71 is stored in advance in the hard disk 100d in FIG. In the present embodiment, the predetermined time used in step S71 is a predetermined time for displaying the received image, and is described as being, for example, “10” seconds, but is not limited thereto. One skilled in the art can determine more suitable values by experimentation.

  After step S71, the determination unit 107 determines whether the received image has been displayed a predetermined number of times by executing the same process as step S62 of FIG. 15 (step S72). At this time, if the determination unit 107 determines that the received image has not been displayed a predetermined number of times (step S72; No), it performs a process similar to step S63 in FIG. 15 to determine whether the display timing has arrived. Is determined (step S73). At this time, when the determination unit 107 determines that the display timing has arrived (step S73; Yes), the determination unit 107 determines the intermittent time based on the number of times of user detection represented by the information stored in the received image table of FIG. Step S74a). Specifically, the determination unit 107 shortens the intermittent time as the number of user detections increases. This is because an image with a larger number of user detections has a higher display frequency.

  Thereafter, the determination unit 107 repeats the above-described processing from step S72 after setting the display timing to the timing after the intermittent time (or before the intermittent time) represented by the value of the variable from the system date and time (step S74b).

  In step S72, when the determination unit 107 determines that the received image has been displayed a predetermined number of times (step S72; Yes), the information stored in the received image table in FIG. 19 is deleted, and the fourth determination process ends.

  When the image display device 100 is activated, the display unit 110 in FIG. 18 starts execution of the slide show by executing the same processing as in FIG. At this time, when the display unit 110 determines that the display timing has come and starts displaying the received image, the display unit 110 starts displaying the received image on the user detection unit 105 (hereinafter referred to as a received image display start signal). ) Is output. Thereafter, when the display of the received image is finished, the display unit 110 outputs a signal indicating that the display of the received image is finished to the user detecting unit 105 (hereinafter referred to as a received image display end signal).

  The user detection unit 105 that inputs these signals executes a user detection process as shown in FIG. 21 for detecting a user from a captured image captured by the imaging unit 102 during display of a received image.

  When the user detection process in FIG. 21 is started, the user detection unit 105 determines whether a received image is being displayed based on a signal input from the display unit 110 (step S81). Specifically, the user detection unit 105 determines that the reception image is being displayed from the reception of the reception image display start signal to the reception of the reception image display end signal. At this time, if it is determined that the received image is not being displayed (step S81; No), the processing is repeated from step S81. On the other hand, if it is determined that the received image is being displayed (step S81; Yes), the imaging unit 102 performs imaging by executing the same processing as the user area detection processing in steps S13 and S14 in FIG. Image information representing an image is input (step S82), and a user is detected by detecting a user area from the input captured image (step S83). Thereafter, the user detection unit 105 determines whether or not a user has been detected (step S84). If it is determined that a user has not been detected (step S84; No), the above processing is repeated from step S81. On the other hand, if it is determined that the user has been detected (step S84; Yes), the number of times indicated by the detection number information is incremented by the value “1” in the user detection number information stored in the received image table of FIG. After updating to the information indicating the value (step S85), the process returns to step S81 and the above processing is repeated.

  The transmission unit 115 in FIG. 18 acquires the information indicating the number of times of user detection stored in the reception image table in FIG. 19 and the reception image ID in a predetermined cycle such as one day, and then displays the acquired information. The evaluation of the image identified by the received image ID is determined based on the number of times the user is detected. Specifically, the transmission unit 115 reads information representing the predetermined threshold Th1 and information representing the threshold Th2, for example, from the hard disk 100d in FIG. 2, and the number of times of user detection is “0” or more and less than the threshold Th1. In some cases, the rating is determined as one star, and when the number of user detections is greater than or equal to Th1 and less than the threshold Th2, the rating is determined as a two-star rating that is higher than one star. In some cases, a three-star rating that is higher than the two-star rating is determined. Thereafter, the transmitting unit 115 transmits the received image ID of the received image and the evaluation information indicating the evaluation of the received image to the server 300.

  When the server 300 receives the received image ID and the evaluation information, the server 300 receives the evaluation information stored in the upload image table of FIG. 17 and is associated with the same upload image ID as the received image ID. Is updated with the received evaluation information. Further, when the evaluation represented by the evaluation information after the update is higher than the evaluation represented by the information before the update, the server 300, depending on the difference between the evaluation before the update and the evaluation after the update, Determine the number of points to add. Specifically, the server 300 determines a larger number of addition points as the evaluation after the update is higher than the evaluation before the update. Next, the server 300 represents the number of points associated with the same upload image ID as the received received image ID by adding the number of added points to the number of points represented by the point number information. Update to information.

  According to these configurations, the information representing the evaluation determined based on the number of times the user is detected from the captured image captured while the received image received from the server 300 is displayed is identified with the received image. Image identification information (that is, received image ID) to be transmitted to the server. For this reason, the server can easily specify an image having a high evaluation (that is, a number of times viewed by the user) among the transmitted images.

  According to these configurations, when the server 300 receives the evaluation information representing the evaluation of the image transmitted to the image display device 100 among the uploaded images, the server 300 represents the evaluation of the image based on the received evaluation information. The evaluation information is updated, and the number of points of the user who uploaded the image is updated based on the evaluation represented by the received information. Therefore, the server 300 can easily identify an image that attracts the user because the evaluation is high, and can give the user a motivation to upload an image with a high evaluation.

  In the present embodiment, the image display device 100 can employ a configuration that receives image information of an uploaded image associated with evaluation information that represents an evaluation higher than a predetermined evaluation. According to this configuration, the image display apparatus 100 receives an image with an evaluation of other users higher than a predetermined evaluation among the uploaded images, and displays the received image. Can also prevent the displayed image from becoming monotonous.

However, the present invention is not limited to this. Rather, those skilled in the art can determine the optimum value by experiment.

  Thereafter, the determination unit 107 sets the display timing to the timing after the intermittent time (or before the intermittent time) represented by the value of the variable from the system date and time (step S105b), and then returns to step S103 and repeats the above processing.

  In step S103, when the determination unit 107 determines that the advertisement image or news image has been displayed a predetermined number of times (step S103; Yes), the image information of the news image or advertisement image stored in the temporary storage unit 104 of FIG. 22 is deleted. After that, the fifth determination process is terminated.

  The display unit 110 in FIG. 22 is an image represented by the image information stored in the image information storage unit 108, and when the display timing comes during execution of the slide show that sequentially displays the images targeted for the slide show. The synthesized image obtained by synthesizing the character image or the character image constituting the advertisement image or the news image is displayed on the image to be the target of the slide show. This synthesized image is, for example, an image obtained by synthesizing a character image or a character image on the upper left or upper right of an image targeted for a slide show, such as a time display, or, for example, a slide show, such as a caption display. It may be an image obtained by synthesizing a character image or a character image below the image.

  According to these configurations, when the viewer layer targeted for the advertisement represented by the advertisement image or the viewer layer targeted for the news represented by the news image is detected from the captured image, the advertisement image or news An image is displayed. For this reason, while being able to advertise more reliably or communicate news to users who are targeted for advertisement or users who are to be notified of news, it is possible to advertise to users who are not targeted. And transmitting news can be prevented more than before. In addition, since the display frequency increases as the number of display times of the advertisement image or news image decreases, it is possible to preferentially display the advertisement image or news image that the user is not familiar with. Can be advertised and news that the user does not know can be preferentially communicated. Furthermore, if the user is positioned in the direction in which the image is displayed, an advertisement image or a news image targeted for the user is displayed, so that the user can be motivated to view the displayed image.

  For example, even when the image display device 100 is in a power-off state, if a news image or an advertisement image is periodically distributed or received by a push from a server, the image display device 100 automatically transitions to a power-on state. A slide show that intermittently displays news images or advertisement images may be started. Further, the server 300 may transmit evaluation information of the uploaded image or point number information of the user to a terminal device used by the user who uploaded the uploaded image.

  The image display apparatus 100 according to the fifth embodiment includes an imaging unit 102, an information input unit 103, a temporary storage unit 104, a user detection unit 105, a determination unit 107, an image information storage unit 108, an information acquisition unit 109, as illustrated in FIG. A display unit 110, a reception unit 114, and a transmission unit 115 are included. Since these functional units are the same as the functional units described in the first to fourth embodiments, a duplicate description is omitted.

  When the transmission unit 115 in FIG. 27 transmits a request for transmission of an application to the server 300, the reception unit 114 receives the application and the application ID of the application from the server 300. Thereafter, the reception unit 114 outputs the received application and application ID to the application image generation unit 116.

  The CPU 100a of the image display device 100 functions as the application image generation unit 116 in FIG. 27 by executing the application received by the reception unit 114. The application image generation unit 116 generates an application image by executing the output application, and outputs image information representing the generated application image and the application ID of the application to the information input unit 103. For this reason, the application image generation unit 116 is referred to as an image output unit OT. In FIG. 27, not only the application image generation unit 116 but also a reception unit 114 and an imaging unit 102, which are also referred to as an image output unit OT, are illustrated. However, the image display apparatus 100 includes an image output unit OT. It is further provided with other functional parts called.

  The temporary storage unit 104 stores an application image table as shown in FIG. The application image table includes an application ID, image information of the application image (hereinafter referred to as application image information), and image information of the application image whose display mode has been changed (hereinafter referred to as changed image) (hereinafter referred to as changed image information). And information indicating the number of detections of the user detected from the image captured by the imaging unit 102 during the display of the changed image (that is, the number of times of user detection) are stored in association with each other.

  The information input unit 103 inputs application image information and an application ID from the application image generation unit 116. Next, the information input unit 103 temporarily stores the input application image information, application ID, and information indicating that the number of detections is “0” in the application image table of FIG. .

  The user detection unit 105 detects the user from the image captured by the imaging unit 101 during the display of the application image by executing the same process as the user detection process of FIG. 21, and stores it in the application image table of FIG. The updated information indicating the number of times of user detection is updated to information indicating the number of times that the number of times of user detection indicated by the information is incremented by “1”.

  When the application image information is input from the application image generation unit 116, the information input unit 103 acquires the system date and time, and sets the acquired system date and time as the input date and time of the application image. Thereafter, the information input unit 103 outputs input date / time information representing the input date / time to the determination unit 107.

  The determination unit 107 executes a sixth determination process (not shown). When the sixth determination process is started, the determination unit 107 sets the timing within the predetermined time from the input date and time represented by the input date and time information input from the information input unit 103 as the display start timing of the application image. Is the next display timing of the application image. Then, after executing the processing from step 72 to step 74b in FIG. 20, the execution of the sixth determination processing is terminated.

  Information representing a predetermined time used in the sixth determination process is stored in advance in the hard disk 100d in FIG. In the present embodiment, the predetermined time used in the sixth determination process is a predetermined time for displaying the application image, and is described as being, for example, “1” seconds, but is not limited thereto. Rather, those skilled in the art can determine a more suitable value by experimentation.

  27 obtains the information indicating the number of times of user detection stored in the application image table in FIG. 28 and the application image ID in a predetermined cycle such as one day, and then displays the obtained information. The evaluation of the application identified by the application ID is determined based on the number of user detections performed. Thereafter, the transmission unit 115 transmits the application ID and evaluation information representing the determined evaluation to the server 300.

  When the server 300 receives the application ID and the evaluation information, the server 300 updates the evaluation information associated with the received application ID with the received evaluation information, and determines the difference between the evaluation before the update and the evaluation after the update. The number of points to be added is determined accordingly. Next, the server 300 updates the point number information associated with the received application ID to information representing the number obtained by adding the added point number to the point number represented by the point number information.

  Further, the transmission unit 115 transmits a request for requesting transmission of extension data to the server 300 in a predetermined cycle or in response to a signal output from the operation button 100i of FIG. 2 operated by the user. Specifically, the transmission unit 115 searches the application image table of FIG. 28 for information indicating the number of times of user detection greater than a predetermined number of times, and acquires an application ID associated with the searched information. Next, the transmission unit 115 transmits the acquired application ID and a request for requesting transmission of extension data of the application identified by the application ID to the server 300.

  When the server 300 receives the application ID and the request from the image display apparatus 100, the server 300 searches the application table in FIG. 26 for extension data associated with the received application ID, and uses the searched extension data and application ID. It returns to the image display apparatus 100.

  When receiving the extension data, the reception unit 114 of the image display apparatus 100 outputs the received extension data to the application image generation unit 116. The application image generation unit 116 generates an application image having a mode different from the display mode of the application image generated without using the extended data by executing the application using the output extended data. Specifically, by executing an application program (that is, an application) that displays a frame of a photo frame using the extended data, a frame that is more excellent than an image that represents a frame generated without using the extended data. Change the image to represent. Further, the application image generation unit 116 identifies the frame selected by the user from among the types of frames newly added in the extended data based on the signal output from the operation button 100i in FIG. An image representing the framed image may be generated.

  Similarly, the application image generation unit 116 may newly generate an application image representing a calendar or a clock selected by the user, which is a design newly added with the extended data, or may be newly added with the extended data. An application image representing a virtual pet or virtual doll wearing the costume selected by the user may be generated.

  The application image generation unit 116 outputs the image information of the application image (that is, the changed image) generated using the extension data to the information input unit 103 together with the application ID. The information input unit 103 inputs the application ID and the image information of the changed image (that is, the changed image information) from the application image generation unit 116, and the input application ID and the changed image information are input to the application image shown in FIG. Save it in association with the table.

  The display unit 110 in FIG. 27 executes a slide show that sequentially displays images that are images represented by the image information stored in the image information storage unit 108 and that are targeted for the slide show. When the display timing comes during execution of the slide show, the display unit 110 displays the changed image represented by the changed image information when the changed image information is stored in the application image table of FIG. When the image information is not stored, the application image before change represented by the application image information is displayed. The display unit 110 may display the application image before the change and the application image after the change (that is, the changed image) separately from the image that is the target of the slide show, or the image that is the target of the slide show. In addition, a composite image obtained by combining the application images may be displayed.

  According to these configurations, the display mode of the application image is changed according to the number of times the user is detected from the captured image captured while the application image is displayed, and the application image is displayed in the changed display mode. . For this reason, since the display mode of the application image may be changed when the user visually recognizes the application image, it is possible not only to prevent the displayed image from becoming monotonous but also to motivate the user to view the displayed application image. Can be given to the user.
