Description

  The present invention relates to an information display device that displays a screen corresponding to a predetermined application on a display unit, and in particular, operates an application such as an e-mail function, a browser function, a telephone book function, and the like. The present invention relates to an information display device that detects and warns that a person is peeping while displaying the content of the user.

  An information display device such as a mobile phone device does not choose a place to use. For this reason, when displaying e-mail or Internet contents on the premises of a station or on a train, the display screen may be looked into by others. Also, for information display devices such as stationary personal computers, other people may look into the display screen while displaying e-mail or Internet content.

  For example, in an automated teller machine (ATM device), it has been proposed to call attention when others are in a peekable position during operation (see, for example, Patent Document 1).

  Also, the operator of the automated teller machine itself analyzes the camera image of the bank account from the time the password is entered, and if it detects that it is a person other than the bank account user himself, warns or calls a specific phone It has been proposed to notify numbers (for example, see Patent Document 2).

  As a method for preventing peeping in a conventional mobile phone device, there is a method of attaching a so-called peeping preventing sheet. If the peep prevention sheet is attached to the display unit of the mobile phone device, the viewing angle of the display unit is narrowed, and the contents of the display unit cannot be seen by a person who is outside the viewing angle. However, when someone else's head is directly behind your head, such as in a train, you may easily see someone else's eyes within a narrow viewing angle. In this case, it is often not noticed even if it is peeped. Also, if a peep prevention sheet that narrows the viewing angle is pasted, it is inconvenient to simultaneously show the content displayed on the display unit of the mobile phone to a plurality of people such as friends.

  Even in a mobile phone device like the above automatic teller machine, it is convenient if the device itself determines whether a person near the operator is looking into the display screen and gives a warning. In addition, when the person who operates the mobile phone device is not the owner, if the device itself judges that and prohibits the operation, personal information such as e-mail and phone book information of the mobile phone device It is convenient not to be looked into.

  Therefore, for a camera-equipped mobile phone device, information on the iris of a person within a predetermined range where the display unit can be seen is extracted using a camera provided near the display unit and registered in the storage means in advance. A method has been proposed in which, when it is determined that someone is peeping, it is warned and the display is interrupted so that the display content cannot be looked into. However, theoretically, it would be possible to use iris recognition technology for peep detection, but before collating, the iris data of multiple people who are allowed to operate the mobile phone device and view the display unit are registered in advance. From the viewpoint of ease of use, there was a question as to whether it can be easily installed in a general mobile phone device (see, for example, Patent Document 3).

  Further, there is a case where the user wants to continue to look at the display portion even when a warning is given that someone is looking into the display content of the mobile phone device. In such a case, change the angle of the hand holding the mobile phone device that keeps displaying, or change the direction of your body to avoid peeping, so that you can not see it from others who are peeping It would be convenient if the display unit could be shifted to the position or angle. The same applies to information display devices such as stationary personal computers.

However, the conventional technology merely gives a warning of being peeped, and does not give any consideration to showing who is looking from which direction. Therefore, even if you know that you are peeping, you can see how you can change the way you hold the mobile phone device, change the direction of your body, change the angle of the screen, I did n’t know what to close.

  The present invention relates to a person who can occupy an information display device such as the owner of the information display device (hereinafter referred to as “exclusive person” for the sake of simplicity), a part of operation and display. “Approved Person” approved by “Exclusive Person” can be easily registered, and recognizes whether the operator is “Exclusive Person” or “Approved Person”. It is a first object to realize an information display device that can do this.

  In addition, the present invention also allows a person who is not authorized to operate the information display device or view the display content of the display unit other than the “exclusive person” or the “approved person” to look into the display content of the display unit of the information display device. When you see it, you can detect it and warn you, and you can be notified that you are peeping into a predetermined person's telephone device or e-mail receiver. A second problem is to realize an information display device that can show whether a person is peeping.

  Furthermore, the present invention is not limited to indicating to which position a person is peeping with respect to the information display device, and a method for changing the viewing angle of the display unit so as to block the line of sight of the peeping person. A third problem is to provide an operator with a specific method for avoiding peeping, and to realize an information display device that automatically executes the specific method.

  The present invention provides an information display device that displays a screen corresponding to a predetermined application on a display unit, a camera unit arranged in the vicinity of the display unit, a face image database, a face image collating unit, a peeping state analyzing unit, In the face image database, the face image of the person who owns the information display device and the face image of the person to be approved are stored, and when the application of the information display device operates, the camera means creates a region facing the display unit. The face image collating unit extracts the face image from the captured image, collates the extracted face image with the face image stored in the face image database, and the peeping state analyzing unit collates the face image collating unit. As a result, when the face images stored in advance do not match, it is determined that the user is peeping, and the determination result is displayed on the display means.

  For this reason, when an operator of the information display device operates a predetermined application such as an e-mail browsing or Internet content image browsing screen, the camera recognizes an image of the operator and a person in the vicinity with the camera, and operates and displays When a person who is not authorized to browse is detected, not only is the operator notified by outputting voice or text, but also the peeping status is displayed.

  Here, the predetermined application may indicate any one application in a predetermined function group such as an e-mail function, a browser function, and a phone book function, A plurality of applications that are operated in a complex manner such as when a telephone directory is called and displayed from the mail function or when a predetermined function such as a browser content browsing screen is operated may be shown.

  As a result, only the owner and the authorized person can view the device for controlling functions according to the application to be used. Can understand the situation.

  In addition, when the present invention is peeped from around the operator who is operating the information display device, the operator is not only notified by outputting voice or text, but also presents the peeping situation. In addition, a method for avoiding peeping is shown, and a method for avoiding peeping is automatically executed.

  For this reason, if you are peeping from around the operator who is operating the information display device, you can not only warn you but also understand the situation and know how to avoid peeping. You can act to block your vision. In particular, an information display device that automatically performs an avoidance operation avoids peeping so as to block the visual field of the person who is peeping without taking any special action as it is. be able to.

  In addition, the present invention is configured such that when a function other than the standby of the information display device or the screen display is operated, for example, when the casing is opened, the peep prevention mode is always set, or when the casing is not opened, a predetermined application is When it works, it is set to the peep prevention mode.

  For this reason, when there is a possibility that the information display device of the present invention is peeped, the peeping prevention mode can be automatically set.

  According to the present invention, the operator who operates the information display device by comparing the face image of the operator captured by the camera unit with the face image of the person who owns the information display device or the face image of the person to be approved Since it is confirmed that the display device is an exclusive person or an approved person, the persons who can operate the information display apparatus and view the display unit can be limited to the exclusive person and the approved person.

  As a result, it is possible to prevent impersonation of the exclusive person and impersonation of the person to be approved. There is an effect that it can be used to limit the range that can be operated for each person and the range that can be viewed the display unit. In addition, it is possible to indicate from which direction the person at which position is looking into the information display device. And the peeping avoidance method which changes the viewing angle of a display part so that the visual field of the person who is peeping may be interrupted can be shown. Also, the viewing angle can be changed to automatically avoid peeping.

  Hereinafter, in the best mode for carrying out the present invention, a mobile phone device which is one of information display devices will be described.

(Embodiment 1)
The information display device according to Embodiment 1 of the present invention extracts a face image from a camera image of an operator who is looking directly at the display unit when in use, and stores an electronic phone book with a face image stored in a mobile phone device in advance. When the face image of the exclusive person and the person to be approved registered in the face image database is collated and it is detected that the person who is looking directly at the display unit is not a person who is not an exclusive person and is not an approved person, It is determined that a person who is not an exclusive person or an unapproved person is peeping, notifies that it is peeping with a warning sound or a warning message, presents the peeping situation, and then is performed on the information display device Stop the operation.

  FIG. 1 shows an external view of mobile phone device 100 according to Embodiment 1 of the present invention. The cellular phone device 100 includes a first casing 1 provided with an input unit 10 such as a numeric keypad, a display unit 20 including a liquid crystal display unit, and a second casing including a camera unit 21 including a CCD camera. 2 is configured as a foldable mobile phone device that is coupled to the hinge portion 3 so as to be opened and closed. The storage device (not shown) of the mobile phone device 100 has an electronic phone book, which registers the phone number, the name and face image of the exclusive user who uses the mobile phone device exclusively, and the exclusive user performs some operations. And the phone number, name and face image of the person to be approved who has approved the viewing of the display. For persons other than the owner and the person to be approved, the telephone number and name are registered. Here, regarding the face image, it is assumed that only the face image of the person who owns the mobile phone device 100 and the face image of the person to be approved are registered, and face images are not registered in the electronic phonebooks of other people. .

  When the mobile phone device 100 is used, the operator holds the first casing 1 by hand, opens the second casing 2, and displays an e-mail text on the display unit 20 or a content screen downloaded from the Internet. Can be displayed.

  When an operation of viewing an e-mail text or content screen displayed on the display unit 20 is performed, the mobile phone device 100 activates the camera unit 21 to view the operator who is viewing the display unit 20 and the surrounding scene. Take an image. Then, a face image is extracted from the captured image. If there is a face image, the face image registered in the electronic telephone directory is checked. When the face image matches the face image of the exclusive person or the person to be approved, all or part of the operation can be performed, or the display content on the display unit can be browsed.

  If the face image captured by the camera unit 21 does not match the face images of the exclusive person and the person to be approved registered in the electronic telephone directory, it is determined that the person is looking into the face image. When it is determined that the user is peeping, a warning is displayed on the buzzer (not shown) or the display unit 20 to give a warning. Also, present the peeping situation. That is, the position of the person who is looking into the mobile phone device 100 is located and from which direction, and the position of the person looking into the mobile phone device 100 is looked into. Is displayed on the display unit 20. Then, the application that has started to operate is terminated.

  FIG. 2 shows a block diagram of a characteristic part of the present invention of the cellular phone device 100. In FIG. 2, description of blocks related to general functions such as a telephone communication function is omitted. FIG. 2 shows that the camera unit 21, the input unit 10, the display unit 20, the phone book database 101, and the application processing unit 102 are connected to the control unit 103.

  Here, the camera unit 21, the input unit 10, the display unit 20, and the phone book database 101 are as described above. In particular, the phone book database 101 registers the profile of the dedicated person 108 of the mobile phone device 100, that is, the address, name, age, face image, etc., and also part of the operation of the mobile phone device 100 and browsing of the display unit. Are registered profiles with face images of a plurality of approved persons 109 who have been approved. The phone book database 101 indicates that the phone book data 110 without a face image is registered as a refusal subject who refuses all operations and browsing.

  The application processing unit 102 executes specific operations such as an e-mail application operation and an Internet browser application operation. Here, the predetermined application may indicate any one application in a predetermined function group such as an e-mail function, a browser function, and a phone book function, It is assumed that a plurality of applications that operate in a complex manner such as when a telephone directory is called from the mail function or when a predetermined function such as a browser content browsing screen is operated may be indicated. To do.

  The control unit 103 is provided with an application determination unit 104 to monitor what operation the application processing unit 102 is processing. A camera unit 21 is connected to the application determination unit 104, and the peeping prevention mode is activated when, for example, an electronic mail browsing operation starts according to the content of the operation of the application processing unit 102. To work.

  Here, the peeping prevention mode refers to the activation of the camera unit 21 when some kind of display is performed on the display unit 20 like an e-mail, and the surroundings of the operator and the operator are imaged. The face image is extracted from the face, and the extracted face image is compared with the face image of the person who owns the information display device, part of the operation, and the face image of the person who is approved to view the display. This is an operation mode in which a warning is given when the images do not match.

  When the peeping prevention mode is activated, the face detection in the control unit 103 is performed by extracting the face image of the operator who is operating the information display device from the image captured by the camera unit 21 as the first stage operation. Send to part 105. The control unit 103 has a dedicated face recognition unit 106 for collating the sent face image with the face image of the dedicated person registered in the telephone directory database 101, and the face sent to the face detection unit 105. Check the image against the face of the owner. If the face image matches the face image of the exclusive person, the exclusive face recognition unit 106 allows the operator to perform all operations. That is, after allowing the operator to perform all operations, the operation from the input unit 10 is accepted and the operation is performed according to the operation.

  If the face image of the operator does not match the face image of the exclusive person, it is verified whether or not the operator is an authorized person. That is, the control unit 103 has an approved person face recognition unit 107 for collating an operator's face image captured by the camera unit 21 with an approved person's face image registered in the telephone directory database 101. Then, the face image of the operator and the face image of the person to be approved are collated. If the face image of the person around the operator matches the face image of the person to be approved, the person-to-be-recognized face recognition unit 107 permits only an operation permitted for the person to be approved. That is, operations permitted for the input unit 10 are operated as operated, but operations that are not permitted are not operated.

  When the face image captured by the camera unit 21 is neither a dedicated person nor an approved person, it is determined that the person is a refusal person, and no corresponding operation is performed even if the input unit 10 is operated. Displays the status of the peeping that was captured. As a result, it is possible to directly warn a person who is neither a dedicated person nor an approved person. Also, if an image of the peeping situation is stored, it can be left as evidence that anyone has peeped.

  Then, as a second step in the peeping prevention mode, a face image of a person around the operator of the information display device is extracted from the image captured by the camera unit 21 and sent to the face detection unit 105. In the control unit 103, the face recognition unit 106 and the person-to-be-recognized face recognition unit 107 collate the face image sent to the face detection unit 105, and the faces of persons around the operator of the information display device When the image is neither the face image of the exclusive person nor the face image of the person to be approved, it is determined that the user is peeping. When it is determined that the user is peeping, a warning sound is emitted with a buzzer (not shown) and a warning message indicating that the user is peeping is displayed on the display unit 20. Then, the image captured by the camera unit 21 is displayed on the display unit 20 as a “peeping situation”. When the “peeping situation” is displayed, not only the operator of the mobile phone device 100 but also the person who is peeping into the mobile phone device 100 is seen, so that the person who is peeping can be warned directly. .

  Next, the operation of the first stage in the peep prevention mode of the cellular phone device 100 of the present invention will be described. FIG. 3 shows a flowchart for explaining the operation of the mobile phone device 100. Here, description will be made assuming that an application operation for displaying an electronic mail has started.

  First, when an e-mail display application operation starts (step S01), the camera unit 21 captures a face image of a person viewing the display unit from the front, and collates it with a face image registered in the telephone directory database.

  If the face image captured by the camera unit 21 matches the face image of the exclusive person (YES in step S02), the operation is continued without restriction (step S03). When the application operation ends, the process ends (step S04). If the face image captured by the camera unit 21 does not match the face image of the exclusive person (NO in step S02), the face image captured by the camera unit 21 and the face image of the person to be approved are collated.

  If the face image captured by the camera unit 21 matches the face image of the person to be approved (YES in step S05), the permission content set for the person to be approved is confirmed (YES in step S06), and is restricted. The operation in the range is continued (step S07). If it is determined in step S05 that the face image captured by the camera unit 21 does not match the face image of the person to be approved (NO in step S05), the person who is viewing the display unit from the front is the person who owns the mobile phone device 100. It is determined that the person is not an approved person and is peeping.

  Then, the user is notified by peep or voice message such as a voice message that the user is peeping or illegal use, and the operation for the subsequent operation is stopped (step S08). And the image which shows the condition of the peeping which the camera part 21 imaged is displayed on the display part 20 (step S09).

  As described above, in the first embodiment of the present invention, in order to check whether the operator of the mobile phone device is a dedicated person or an approved person, if the mobile phone device is operated as an owner or an approved person, It can be determined that the sound is displayed, a warning is given by sound and a display unit, and a peeping situation can be presented.

  Next, the operation of the second stage in the peep prevention mode of the mobile phone device 100 of the present invention will be described. In the second stage of the peeping prevention mode, in addition to the operator looking directly in front of the display unit, the face image of the person around the operator is extracted from the camera image, and the face image of the exclusive person is extracted. And the face image of the person to be approved.

  In other words, the verification of the operator who is looking directly at the display unit is as described above, and when it is determined that another person around the operator is looking into the display unit, Notify the user with a warning sound or warning message, indicate the position of the person who is peeping, and change the viewing angle so that the person who is peeping cannot see the display Take measures such as

  The operation of the second stage of the peep prevention mode of the cellular phone device 100 of the present invention will be described with reference to the flowchart of FIG. 4 and the transition diagrams of the display contents of the display unit of FIGS.

  In FIG. 4, for a person in front of the display unit 20, an operation when the face image captured by the camera unit 21 matches the exclusive person (step S <b> 03), an operation when the face image matches the person to be approved (step S <b> 07), The operation (step S08) when the exclusive person and the person to be approved do not match is the same as that in FIG.

  In the second stage of the peep prevention mode, after performing the processing operation for the operator who is looking directly at the display unit 20, the operator is looking at the display unit 20 from around the operator. It is determined whether or not. More specifically, it is extracted whether or not there is another face image around the face image of the person who is looking directly in front of the display unit 20 of the image captured by the camera unit 21, and for all the extracted face images. And check if you are peeking.

  For example, when eight face images of a person looking directly in front of the display unit 20 are extracted, the line of sight faces the display unit 20 one by one from the face images close to the person looking directly in front of the display unit 20. Check for all 8 people. If the line of sight faces the display unit 20, the face image of the person is collated with the face image registered in the electronic telephone book, that is, the face image of the exclusive person and the face image of the person to be approved. If the face image of the person around the operator does not match the face image registered in the electronic phone book, it is determined that the person is peeping from the surroundings. This check is performed for all members (step S10).

  When even one of the face images around the face image of the person looking directly in front of the image display unit 20 is peeping from the surroundings, it is determined that the person is “peeking”. When it is determined that the person is peeping (YES in step S11), the position of the person peeping in and the direction of peeping are analyzed (step S12), and as shown in FIG. A specific situation is displayed on the display unit 20.

  In FIG. 5, the specific situation of peeping is displayed as a plan view seen from above the head. In FIG. 5, 30 indicates the position and orientation of the display unit 20 of the mobile phone device, 31 indicates a line indicating the field of view range, 32 indicates an operator located directly in front of the display unit, and 33 indicates a peeping person. ing. “Peeping direction” is indicated by the direction of the body of 33 persons. Although 34 is around the person 32 but the line of sight does not face the display unit 20, the person who is not peeping is represented by a broken line instead of a solid line (step S13).

  Then, a peeping avoidance method is displayed on the display unit 20 as shown in FIG. In FIG. 6, how to change the direction of the display unit 20 is indicated by a character message 41 and an arrow 42, and the direction of the display unit to be changed is indicated by a broken line 43 and a two-dot chain line 44 (step S14). Then, the application processing operation ends (step S16).

  Even if there is another face image around the face image of the operator who is looking directly in front of the display unit 20 in step S11, if the line of sight does not face the display unit 20, it is determined that the person is not peeping. . Even if there is another face image around the face image of the operator looking directly in front of the display unit 20 and the line of sight faces the display unit 20, the other face image is registered in the electronic telephone directory. When the face image matches the face image of the owner, that is, the face image of the person to be approved or the face image of the person to be approved, it is determined that the person is the owner of the owner or the person who has been approved to view and is not peeped (NO in step S11). ). When it is determined that the user is not peeping, the application operation is performed and the process ends.

  In FIG. 5, the specific situation of the peeping is displayed as a plan view seen from above the head. However, as shown in FIG. 7, the left and right of the image captured by the camera unit 21 may be mirrored and shown. Good. This makes it possible to grasp the situation without turning around. In addition, when a realistic image is displayed in this way, the person who is peeping at the screen is shown to be peeking at the person, so that there is an effect that the warning can be made stronger.

  Thus, when a person around the operator who is looking directly at the display unit 20 is looking into the display unit, a specific situation of the peeping is displayed on the display unit. Therefore, it is possible to easily escape from the state of peeping by changing the way of holding the mobile phone device or changing the position of the body.
