It is a figure which shows the example of a screen as which the image was displayed by the multi display format.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment described below is an embodiment when the present invention is applied to an image display device.

[ 1. Configuration and function of image display apparatus ]
First, the configuration and function of the image display apparatus according to the present embodiment will be described with reference to FIG.

  FIG. 1 is a diagram illustrating a schematic configuration example of an image display apparatus according to the present embodiment.

  As shown in FIG. 1, an image display device S includes a display (display device) 1, a camera 2, a microphone 3, a storage unit 4, an operation unit 5, a communication I / F 6, a control unit 7, an electronic information reader 8, and the like. It is configured with.

  The display 1 is attached to, for example, a photo frame, and is installed at a position where a plurality of people (residents) can see the screen of the display 1 in a room of a house or office, for example. The camera 1 picks up the sound uttered by the person existing in the predetermined place in the room, and the microphone 3 collects the sound emitted by the person existing in the predetermined place in the room. The electronic information reader 8 is installed at a position where it can be confirmed that the electronic information reader 8 exists at a predetermined place such as the entrance of the room.

  The storage unit 4 includes, for example, a hard disk or a nonvolatile semiconductor memory, and stores various programs and data. In addition, a registrant information database (DB) 41 is constructed in the storage unit 4.

  FIG. 2 is a diagram illustrating an example of contents registered in the registrant information database 41.

  In the registrant information database 41, registrant information and image data (for example, an image file in a format such as TIFF, GIF, or JPEG) are registered (stored) in association with each other. The registrant information includes, for example, the name of a person who is expected to be at home, identification information (ID), and registrant feature information for identifying the registrant (for example, registrant face image data, voice feature) Data, card ID) and the like. The name and identification information (ID) included in the registrant information are input and registered from the operation unit 5 by, for example, a person at home. Further, the image data and the registrant characteristic information are transmitted by the control unit 7 in accordance with an instruction from the operation unit 5 by a person at home via the communication I / F 6 and communication means (for example, a digital camera, a portable terminal, a personal computer, Server). A person whose registrant information is registered in the registrant information database 41 is hereinafter referred to as a “registrant”.

  Further, the image related to the image data associated with the registrant information is, for example, an image (photo image) showing the appearance of each registrant or an image taken by each registrant. Multiple image data can be registered.

  The control unit 7 includes, for example, a microcomputer and the like, and when a predetermined program (the image display control program of the present invention) is executed by the computer, the occupant determination unit 71 (the recognition unit and the determination unit of the present invention). An example), a stay time calculation unit 72 (an example of stay time calculation means), a recognition order determination unit 73 (an example of recognition order determination means), a display control unit 74, and the like (an example of a control means in the present invention).

  The at-home person determination unit 71 recognizes a person existing at a predetermined location in the room (for example, entering the room). For example, if a person's face image can be extracted from the image captured by the camera 2, the person can be recognized (who is unknown at this time). Since the method for extracting a human face image is well known, detailed description thereof is omitted.

  Then, the resident determination unit 71 determines whether or not the registrant information corresponding to the recognized person is registered in the registrant information database 41. For example, the resident determination unit 71 determines whether or not there is a similarity between the extracted face image and the face image included in each registrant feature information registered in the registrant information database 41, and there is the similarity. When the registrant characteristic information is registered in the registrant information database 41, it is determined that the registrant information corresponding to the recognized person is registered in the registrant information database 41.

  Here, since the method for determining the presence / absence of similarity is well known, detailed description thereof is omitted. For example, facial feature points (for example, eyes, nose, mouth, etc.) that well represent facial features from the extracted face image. Are extracted, and a face graph connecting these feature points is created. Then, based on the created face graph and the face image registered in the registrant information database 41, a face graph created in the same manner as described above (even if the face graph is registered in the registrant information database 41 in advance). If the ratio is equal to or greater than a predetermined value, it is determined that there is similarity. Note that if the orientation of the extracted face image and the registered face image is different, not only will the similarity be lost, but there will also be a problem that face feature points cannot be detected well. Estimate the orientation of the face (for example, estimate the orientation of the face from the shape of a triangle with the right eye, left eye, and mouth as vertices), and convert the face graph according to the orientation to solve the problem be able to.

  Thus, when it is determined that the registrant information corresponding to the recognized person is registered in the registrant information database 41, information indicating the recognition time when the person (registrant) is recognized is the registrant. The at-home person flag corresponding to the registrant stored in the memory (recognition time storage means) in association with the information and stored in the memory is changed from “0” to “1”.

  By the way, when a plurality of people enter the room at, for example, intervals, the resident determination unit 71 sequentially recognizes the plurality of people and corresponds to each recognized person. Whether or not the registrant information is registered in the registrant information database 41 is determined as described above. And about the registrant whose registrant information is registered into the registrant information database 41 among the recognized several person, the information which shows the said recognition time is matched with each registrant information, and is stored in memory. The at-home person flag stored in the memory and corresponding to the registrant is changed from “0” to “1”.

  In addition, the stay time calculation unit 72 calculates the stay time from the recognition time to the current time for each recognized person.

  The recognition order determination unit 73 determines the recognized order of each recognized person based on the recognition time.

  When it is determined that the registrant information corresponding to the recognized person is registered in the registrant information database 41, the display control unit 74 adds the image data associated with the registrant information to the image data. Such an image is displayed on the display 1. On the other hand, when there are a plurality of recognized persons who are registered in the registrant information, an image related to the image data corresponding to each recognized person is displayed in a predetermined display order. Thus, for example, the images are sequentially displayed in a slide show format, or images related to these image data are displayed on the same screen in a predetermined size, for example, a multi display format. Details of such display control processing will be described later.

  In addition, when the registrant who goes out of the room is photographed by the camera 2 and recognized by the resident determination unit 71, the information indicating the recognition time corresponding to the registrant is deleted from the memory and stored in the memory. The stored home flag corresponding to the registrant is changed from “1” to “0”.

[ 2. Operation of image display device S ]
Next, the operation of the image display apparatus according to the present embodiment will be described with reference to FIG.

  FIG. 3 is a flowchart showing an example of image display processing in the control unit 7 of the image display apparatus according to the present embodiment. FIG. 4 shows “display control in the case where there are a plurality of people at home” shown in step S6 of FIG. 4A is a flowchart illustrating a specific example of “process”, FIG. 4A illustrates a slide control display control process, and FIG. 4B illustrates a multi display display control process.

  The process illustrated in FIG. 3 is started, for example, when the control unit 7 periodically captures an image captured by the camera 2 and recognizes a person (face image) from the image. When the processing is started, the control unit 7 (at-home person determination unit 71) is included in the extracted face image and each registrant characteristic information registered in the registrant information database 41 as described above, for example. By determining whether there is similarity to the face image, it is determined whether or not the registrant information corresponding to the recognized person is registered in the registrant information database 41 (step S1). When the control unit 7 (at-home person determination unit 71) determines that the registrant information is registered in the registrant information database 41 (step S1: YES), it corresponds to the registrant information of the registrant. In addition, information indicating the recognition time is stored in the memory, and the resident flag corresponding to the registrant is changed from “0” to “1” (step S2).

  When the control unit 7 (at-home person determination unit 71) recognizes a plurality of people (face images) from the image, each person's face image and each registration registered in the registrant information database 41 are displayed. It is determined whether or not registrant information corresponding to each person is registered in the registrant information database 41 by determining whether or not there is similarity to the face image included in the person feature information. The information indicating the recognition time is stored in the memory in association with the registrant information of the person (registrant) who is registered, and the resident flag corresponding to the registrant is changed from “0” to “1”. It will be.

  On the other hand, when the registrant information is not registered in the registrant information database 41 (step S1: NO), the control unit 7 (at-home person determination unit 71) temporarily distinguishes the unregistered person from the registrant. Specific identification information (ID) is issued, information indicating the recognition time is stored in the memory in association with the identification information, and a resident flag “1” corresponding to the unregistered person is stored in the memory (step) S3).

  Next, the control unit 7 (at-home person determination unit 71) determines whether there are a plurality of at-home persons, for example, by referring to the at-home person flag (step S4). (Step S4: NO), the process proceeds to Step S5, and when there are a plurality (Step S4: YES), the process proceeds to Step S8.

  In step S5, the control unit 7 (at-home person determination unit 71) determines whether the at-home person is an unregistered person by referring to the identification information, and the at-home person is not an unregistered person, that is, registered. When the person is a person (step S5: NO), the process proceeds to step S6. When the person at home is an unregistered person (step S5: YES), the process proceeds to step S7.

  In step S 6, the control unit 7 (display control unit 74) reads image data associated with the registrant information of the registrant whose home-in-home flag is “1” from the storage unit 12 and displays the image on the display 1. It is displayed on the top (display control processing when there is only one resident). At this time, when a plurality of pieces of image data are registered in association with the registrant information, the control unit 7 (display control unit 74) sequentially repeats the images related to these image data in a slide show format, for example. Or display images related to these image data in the multi-display format on the same screen (continuous display).

  In step S <b> 7, the image data for the unregistered person to be displayed in the case of the unregistered person whose home flag is “1” is read from the storage unit 12 and the image is displayed on the display 1. Here, as an image for an unregistered person, for example, an image (such as a group photo image or a landscape image of a plurality of persons) in which an individual cannot be identified visually can be cited.

  Note that after the process shown in FIG. 3 is completed, the process proceeds to other processes. However, the display of the image by the process of step S6 or S7 is maintained, and if a person is recognized again during this process, the process shown in FIG. Will start again.

  On the other hand, in step S8, the control unit 7 (at-home person determination unit 71) determines whether or not an unregistered person is included in the plurality of at-home persons by referring to the identification information, and the plurality of at-home places. If an unregistered person is included in the person (step S8: YES), the process proceeds to step S7, and for example, a landscape image incapable of specifying an individual is displayed. In other words, when there are registered persons and unregistered persons among the home-staying persons, the image for unregistered persons is given priority. Thus, for example, if the staying person in the room is a family (registrant) and a salesman (unregistered person), the landscape image is preferentially displayed, and the registrant's photo image that the salesman does not want to see Can be prevented from being displayed.

  On the other hand, in step S9, the control unit 7 (display control unit 74) reads the image data associated with the registrant information of each registrant with the resident flag being “1” from the storage unit 12, and the image Is displayed on the display 1 (display control processing when there are a plurality of people at home).

  Here, in the display control processing example in the slide show format shown in FIG. 4A, the control unit 7 (display control unit 74) displays the image corresponding to each registrant whose home-in-home flag is “1”. (Display order when one image is displayed on one screen) is determined (step S91).

  For example, the control part 7 (display control part 74) determines the display order of the image corresponding to the said registrant according to the stay time of each registrant in the said room. The stay time is calculated by the stay time calculation unit 72 as, for example, the time from the stored recognition time to the current time. In this case, for example, there are three people whose resident person flag is “1”, that is, registrant A, registrant B, and registrant C. If the stay time is 3 hours and the stay time of the registrant C is 1 hour, the display order is determined in the order of registrant B → registrant A → registrant C. In this case, an image can be displayed earlier (priority) as the staying time is longer. That is, it is possible to realize effective image display according to the length of stay time.

  Or the control part 7 (display control part 74) determines the display order of the image corresponding to the said each registrant according to the recognized order. The recognized order is determined by the recognition order determining unit 73 based on the stored recognition time (that is, the order of entering the room). In this case, for example, similarly to the above, there are three people whose home flag is “1”, the registrant A's recognition time is 19:00, and the registrant B's recognition time is 18:00 on the same day. If the recognition time of the registrant C is 20:00 on the same day, the display order is determined in the order of registrant B → registrant A → registrant C. In this case, an image can be displayed earlier (prioritized) as the person enters the room earlier (the recognition time is earlier). That is, an effective image display according to the order in which each person is recognized can be realized.

  The display order may be determined according to the initial setting (for example, determined in the order of registration of image data).

  Next, the control unit 7 (display control unit 74) determines the display time (the time length of one display) of the image corresponding to each registrant whose display order has been determined (step S92).

  For example, the control part 7 (display control part 74) determines the display time of the image corresponding to each registrant according to the stay time of each registrant in the said room. In this case, the longer the staying time, the longer the image can be displayed. For example, when the image of the registrant B is displayed for 20 seconds, the image is switched to the image of the registrant A, and when the image of the registrant A is displayed for 30 seconds, the image is switched to the image of the registrant C. Thereby, the effective image display according to the length of stay time is realizable.

  Or the control part 7 (display control part 74) determines the display time of the image corresponding to each registrant whose said display order was determined based on the said recognized recognition time according to the recognized order. . In this case, an image can be displayed for a longer time as the person enters the room earlier. That is, an effective image display according to the order in which each person is recognized can be realized.

  The display time may be determined according to the initial setting (for example, the display time of all registrants is determined at the same time).

  Next, the control unit 7 (display control unit 74) reads image data or the like associated with the registrant information of each registrant whose display order and display time are determined from the storage unit 12, and reads the image as described above. According to the determined display order and display time, for example, it is displayed on the display 1 in a slide show format (step S93).

  In addition, after the process shown in FIG. 4A and FIG. 3 is finished, the process shifts to another process, but the image corresponding to each registrant is repeatedly displayed in the determined display order. When the person is recognized again, the process shown in FIG. 3 is started again.

  On the other hand, in the display control processing example of the multi-display format shown in FIG. 4B, for example, the control unit 7 (display control unit 74) displays an image corresponding to each registrant with the resident flag being “1”. The display order (arrangement order when a plurality of images are displayed on one screen) is determined (step S95).

  For example, the display order is determined according to the stay time of each person in the room or the recognized order, as in the process of step S91.

  The display order may be determined according to the initial setting (for example, determined in the order of registration of image data).

  Next, the control unit 7 (display control unit 74) determines the amount or size of the image to be displayed corresponding to each registrant whose display order has been determined (step S96).

  For example, the control unit 7 (display control unit 74) determines the amount (for example, the number) or the size of the image corresponding to each registrant according to the stay time of each registrant in the room. . When determining the amount of images to be displayed, for example, when a plurality of pieces of image data for each person are stored, the longer the staying time, the more images can be displayed on the same screen. Further, when determining the size of an image to be displayed (in other words, the area of the image on one screen), the longer the staying time, the larger the size of the images displayed on the same screen. it can. That is, it is possible to realize effective image display according to the length of stay time.

  Alternatively, the control unit 7 (display control unit 74) sets the amount or size of the image corresponding to each registrant whose display order is determined in the recognized order based on the stored recognition time. Decide accordingly. When determining the amount of images to be displayed, for example, when a plurality of pieces of image data for each person are stored, a person who enters the room earlier can display more images on the same screen. In addition, when determining the size of an image to be displayed, the person who enters the room earlier can increase the size of a plurality of images displayed on the same screen. That is, an effective image display according to the order in which each person is recognized can be realized.

  The amount or size of the image to be displayed may be determined according to the initial setting (for example, the amount and size of each registrant's image to be displayed are determined to be the same).

  Next, the control unit 7 (display control unit 74) stores the image data and the like associated with the registrant information of each registrant for which the display order and the amount or size of the image to be displayed are determined from the storage unit 12. The image is read and displayed on the same screen of the display 1 in the multi-display format, for example, according to the determined display order and the amount or size of the image to be displayed (step S97).

  FIG. 5 is a diagram illustrating an example of a screen on which an image is displayed in a multi display format. In the example shown in FIG. 5, the image size decreases in the order of registrant B → registrant A → registrant C.

  Note that also in the slide show format display control process shown in FIG. 4A, the above-determined display order (display order when one image is displayed on one screen) and the display time of images to be displayed are displayed. The amount or size may be determined according to the stay time of each person corresponding to each image or the recognized order, and may be configured to be displayed on the same screen in a multi-display format, for example. In this case, for example, when the image of the registrant B → the image of the registrant A → the image of the registrant C is displayed in this order, for example, the amount or size of the image of the registrant B displayed on a certain screen is It can be increased or increased depending on the amount or size of the image of the registrant A displayed on the next screen.

  As described above, according to the above embodiment, it is possible to display an image registered for each recognized person while avoiding the complexity of user operations such as logon, and in particular, the display 1 can be displayed by a plurality of persons. Even when sharing images, images registered for a plurality of people can be displayed in order while avoiding the complexity of user operations such as logon. Thereby, the image regarding each person can be effectively shown to each person existing in the predetermined place.

  In the above-described embodiment, the person is recognized from the captured image. However, the person may be recognized by another method. For example, you may comprise so that a person may be recognized from the audio | voice collected with the microphone 3. FIG. In this case, the registrant's voice feature data is registered as the above-described registrant feature information, and voice feature data representing a human voice feature (for example, a voice waveform pattern) is extracted from the collected voice and extracted. The registrant information corresponding to the recognized person is determined by determining whether or not there is similarity between the recorded voice feature data and the voice feature data included in each registrant feature information registered in the registrant information database 41.
