Description

  The present invention relates to a mobile phone with a camera, and more particularly to a mobile phone terminal with a digital camera function to which a voyeurism prevention function is added.

  Many of the mobile phones that have been released recently are equipped with a digital camera function, and users can easily take pictures anytime and anywhere with the camera attached to the mobile phone. However, there is a problem of voyeurism by exploiting its convenience and convenience. In addition, even if the performance of the camera itself is improved and the zoom function is used, detailed shooting can be performed, and a storage medium such as an SD card can be mounted so that the number of registered images does not have to be taken care of. It creates a situation that makes it easier to voyeur.

  In order to suppress such voyeurism using a mobile phone with a camera function, for example, a mobile phone with a camera function that is currently on sale has a function of lighting an LED for shooting display during shooting, or a shutter when a user takes a picture. Some have a function of notifying the surrounding that a photographing operation has been performed by generating a shutter sound in conjunction with the pressing. However, with these methods, it is possible to hide the LED for shooting display during voyeurism, and as a preventive function, for example, in a place where there is a lot of ambient noise such as in a train, the shutter sound is erased by the ambient noise. Sometimes it's useless. Further, once the image is taken, the user can freely register and edit images thereafter.

  In addition, as a technique for preventing voyeurism using a mobile phone with a camera function, in Patent Document 1, the camera-equipped mobile phone has a foldable configuration so that the device cannot be photographed unless the device is opened at a predetermined angle or more, and the photographing is disabled. A method has been proposed in which a warning sound is emitted when shooting is performed to notify the failure of shooting, while the sub-display is turned on at the same time as shooting to notify surrounding people that the shooting operation has been performed. If the camera-equipped mobile phone is equipped with a tilt sensor and the tilt angle of the camera-equipped mobile phone when the shutter button is pressed is within the preset unnatural angle range, the shutter operation is disabled. Thus, a method for generating a warning sound or the like has been proposed.

  Further, Patent Document 3 includes a wireless device that transmits a control signal to a place or area where photographing is prohibited due to security or rights issues, and the mobile phone with a camera function receives the control signal from the wireless device. In such a case, a technique for restricting execution of video acquisition operations such as video information generation / output operation, transmission operation, and storage operation has been proposed.

  In the method described in Patent Document 1 or 2, since the camera function-equipped mobile phone is uniformly in a shooting-prohibited state when it is in a predetermined state, and in other cases, it is possible to perform shooting uniformly, In the mobile phone with camera function described above, when voyeurism is performed with the foldable casing fully opened, it is not possible to prevent shooting, and the camera function described in Patent Document 2 is provided. In the case of a mobile phone, shooting is impossible even when it is necessary to perform normal shooting within a preset angle range in order to prevent voyeurism. There is a problem that, when a voyeurism is performed outside a preset angle range, it cannot be prevented.

  Further, although the method described in Patent Document 3 is effective as a means for preventing voyeurism, it is necessary to include a wireless device that wirelessly transmits a photographing prohibition signal in a place or region where photographing is prohibited, The equipment becomes oversized. In addition, there is a problem that voyeurism in areas other than the prohibited shooting area cannot be restricted.

  In view of the above-mentioned problems, the object of the present invention is a relatively simple means that is more effective than the conventional vague sneak shot suppression measures that generate shutter sound and the like, and that can prevent voyeurs accurately. It is to provide.

  The mobile phone with a camera function of the present invention includes a voyeurism prevention function unit that monitors the depression of the camera activation button, detects that the camera activation button has been depressed, and executes a voyeurism prevention operation. However, when the camera start button is pressed or an instruction to return to the shooting mode is detected, the camera shooting mode is set, and the shooting mode is periodically taken from when the camera shooting mode is set until the shooting button is pressed. It has a function of performing voice guidance to inform the surroundings of this.

  The mobile phone with a camera function of the present invention includes a voyeurism prevention function unit that monitors the depression of the camera activation button, detects that the camera activation button has been depressed, and activates a voyeurism prevention operation. A function for executing a process of forcibly connecting to the Internet, transmitting the captured image to a server and storing the image when the registration unit detects that the registration process of the image captured by the camera is selected. It is characterized by.

  The cellular phone with a camera function of the present invention monitors the press of the camera start button, detects that the camera start button has been pressed, and starts a voyeurism prevention function unit, and manages a shot image. And a storage medium in which image recognition software is stored, and the voyeurism prevention function unit is stored in the storage medium when detecting that registration processing of an image photographed by the camera is selected. A function for determining whether or not a voyeur image is obtained by executing image recognition processing by image recognition software; a function for performing registration processing of the image when it is determined that the image is not a voyeur image; And a function of forcibly terminating the image registration processing.

  In the present invention, it is not ambiguous prevention such as LED light emission or shutter sound generation at the time of shooting, but in the camera shooting mode between the start of the camera and pressing the shooting button by providing a voyeurism prevention function unit inside the mobile phone By controlling the voice guidance that informs the surroundings of the situation, it is possible to clearly communicate that the camera is being shot and to care about the surrounding eyes, thereby preventing voyeurism more accurately before shooting. Can be possible.

  In another embodiment of the present invention, the voyeurism prevention function unit inside the mobile phone executes control for performing image recognition processing before registration processing of the captured image, so that the voyeur can be accurately captured before the user performs image registration. Can be prevented.

  FIG. 1 is a block diagram showing an embodiment of a mobile phone with a camera function of the present invention.

  The mobile phone with a camera function of the present embodiment includes a microphone 1, a speaker 2, a modulation unit 3, a demodulation unit 4, a transmission unit 5, a reception unit 6, a shared unit 7, an antenna 8, and a control unit that have the same functions as those of the prior art. 9, a CPU 10, a camera 12, a voyeurism prevention function unit 11, which is a feature of the present invention, and a storage medium (for example, an SD card) 12.

  The voyeurism prevention function unit 11 and the storage medium 12 have a function of executing various controls for preventing voyeurism as described below when the photographing operation by the mobile phone with camera function of the present embodiment is activated by the user. A control program for this purpose is stored.

  FIG. 2 is a flowchart showing the operation of this embodiment. The operation of this embodiment will be described below with reference to FIGS.

  The voyeurism prevention function unit 11 monitors the pressing of the camera start button by the user (step S1), and when the camera start button is pressed, performs voice guidance for notifying the surroundings that the camera is currently in the shooting mode. (Step S2). As the voice guidance, for example, an incoming call notification speaker built in the mobile phone is used to notify the content such as “I will start shooting” at a volume that can be heard around.

  This voice guidance is repeatedly notified at a predetermined cycle until the next step in which the shooting button is pressed is executed. Further, since the purpose of this voice guidance is to prevent voyeurism by notifying the surroundings that the camera shooting mode is being performed, it is impossible to arbitrarily mute or change the volume in the user settings.

  In addition, several voice guidance modes that the user can select can be prepared. For example, when the self-timer mode is selected by setting the self-timer mode, the voice guidance such as “Press the shutter after 10 seconds. 10, 9,... It is also possible to use it as an audio self-timer by operating the camera so that it automatically presses the shooting button after it has been performed.

  Next, when the user presses the shooting button (step S3), a shooting operation is performed, and at that time, a shutter sound similar to the conventional technology is generated (step S4). Next, it is monitored whether or not the registered processing for the photographed image is selected (step S5). If the button for selecting image registration is pressed, the processing proceeds to the registered processing for the photographed image (step S6). After image registration processing, or when it is selected not to perform image registration, it is monitored whether or not the camera returns to the shooting mode (step S7).

  If the user gives an instruction to exit without returning to the shooting mode, the camera activation is terminated, and the camera waits for the camera activation button to be pressed again (step S1). On the other hand, when the user gives an instruction to return to the shooting mode, an operation for notifying the surroundings again of the voice guidance for notifying the surroundings that the camera shooting mode is being performed is performed via an incoming call notification speaker or the like ( Step S2).

  FIG. 3 is an operation flowchart showing the second embodiment of the present invention.

  In the present embodiment, the camera activation is forcibly prohibited in a specific situation (shooting prohibited area or the like). For this reason, the mobile phone with a camera function of this embodiment is prohibited from being transmitted in the shooting prohibited area. A function is added to prohibit camera activation when a signal is received. Hereinafter, the operation of the present embodiment will be described with reference to FIG.

  When the voyeurism prevention function unit 11 determines that the process (step S1) for determining whether or not the photographing prohibition area is in a specific situation is always in operation and the photographing prohibition signal or the like has been received. Is forcibly prohibited from starting the camera (step S2). Thereafter, when the camera is removed from a specific situation, the camera can be activated (step S3), and thereafter, the operation flow shown in FIG. 2 is executed.

  The above-mentioned specific situation means that a specific signal (photographing prohibition or shooting prohibition or The release activation signal is received, and the camera activation determination circuit provided in the camera-equipped mobile phone that has received this signal is activated to automatically control the activation of the camera. As a means for transmitting and receiving a specific signal between the gate and the portable terminal, BlueTooth, Ir, a contactless authentication system, or the like can be used.

  In this embodiment, since the camera activation itself is controlled in the specific area, voyeurism is reliably prevented. It is also possible to deal with many types of mobile terminals by making the specific signal between the gate and the mobile phone terminal common specifications.

  Also, in the case of a concert hall or train, it is possible to divert the current ticket or commuter pass authentication system using a mobile phone. In other words, when an electronic ticket (barcode) obtained by accessing a ticket sales site on the Internet is displayed on the screen of a mobile phone, the mobile phone is sent out instead of the ticket and read by a bar code scanner or the like to perform admission authentication Camera activation control can also be performed.

  FIG. 4 is an operation flowchart showing the third embodiment of the present invention.

  In this embodiment, when registering a captured image, it is not stored inside the mobile terminal as in the past, but is stored in a server connected to the Internet, and whether or not it is a voyeur image by performing image recognition processing there. This is characterized by preventing voyeurism. The operation of this embodiment will be described below with reference to FIG.

  The voyeurism prevention function unit 11 monitors the pressing of the camera activation button by the user (step S1), and when the camera activation button is pressed, the user then monitors the pressing of the shooting button (step S2). When the user presses the shooting button, a shooting operation is performed, and at that time, a shutter sound similar to that of the conventional technique is generated (step S3). Next, selection of image registration is monitored (step S4).

  If registration of a photographed image is selected, the photographed image is forcibly connected to the Internet and stored in the server (step S5). Therefore, the storage destination of the captured image is the server. After the image is transmitted to the server and registered, or when it is selected not to register the image, it is monitored whether or not to return to the shooting mode (step S6).

  If the user gives an instruction to exit without returning to the shooting mode, the camera activation is terminated, and the camera waits for the camera activation button to be pressed again (step S1). On the other hand, when the user gives an instruction to return to the shooting mode, the process returns to step S2 for monitoring the pressing of the shooting button by the user again.

  In the present embodiment, all images taken by the user are stored by the server, and the server side determines whether the images are voyeur images using image recognition. If the server determines that the image is a voyeur image, the image is deleted. Therefore, even if the user accesses the server after shooting, the image cannot be viewed. In addition, since registration and recognition of captured images are performed by the server, heavy processing such as image recognition can be performed at high speed, and there is no problem in handling large amounts of data. Also, the image recognition software for determining a voyeur image can be upgraded to an optimum version each time, and the user is not particularly aware of it.

  Various determination criteria are prepared for image recognition on the server side. For example, since there are several character images in a voyeur such as a book, it can be determined by pattern matching with a character code, and in the case of a voyeur of a person, the subject's eyes are not facing the camera or the face Since there are several cases where no is copied, it can be determined by performing matching of the eye position and the like by image recognition.

  In the voyeurism prevention method of the present embodiment, a large number of voyeur judgment criteria can be set on the server side, and a user can obtain a voyeur image by deleting what is judged as a voyeur image at high speed. Since it becomes impossible, it becomes a reliable method for preventing voyeurism.

  FIG. 5 is an operation flowchart showing the fourth embodiment of the present invention.

  In the third embodiment, since the registered destination of the captured image is a server, a communication fee for connecting to the Internet is incurred every time an image is registered, viewed, or downloaded from the user's standpoint. Therefore, in the present embodiment, the photographed image is registered / stored in the mobile terminal, and the problem is solved by executing the voyeur determination process by the image recognition software installed in the mobile terminal. .

  Further, if image recognition is performed inside the portable terminal, there is a problem in version management of the image recognition software. In this embodiment, this problem can be solved by performing image recognition processing with the storage medium 13 in FIG. . The operation of this embodiment will be described below with reference to FIG.

  The voyeurism prevention function unit 11 shown in FIG. 1 monitors the pressing of the camera activation button by the user (step S1), and when the camera activation button is pressed, next monitors the pressing of the shooting button by the user (step S2). When the user presses the shooting button, a shooting operation is performed, and at that time, a shutter sound similar to that of the conventional technique is generated (step S3). Next, it is monitored whether or not image registration has been selected (step S4). If it is selected that image registration is not to be performed, it is monitored whether or not to return to the shooting mode (step S9).

  On the other hand, when registration of the photographed image is selected, the version of the image recognition software is checked (step S5). The sneak shot prevention function unit 11 stores the latest version information of the image recognition software, and checks whether the image recognition software stored in the storage medium 13 is the latest version. If it is determined that the version is not the latest version, a message to that effect flows to the user side (step S10) and the process is forcibly terminated.

  Note that the version information of the image recognition software is forcibly updated when the user connects to the Internet or communicates with the center by sending or receiving mail (even if the user does not intend otherwise). It can be configured to be stored internally.

  If the image recognition software is the latest in step S5, a permission signal is issued from the voyeurism prevention function unit 11 to the storage medium 13, and image recognition processing is performed in the storage medium 13 (step S6). Thereafter, the process proceeds to a determination as to whether or not it is a voyeur image (step S7), and if it is not a voyeur image, the process proceeds to an image registration process (step S8). If it is determined that the image is a voyeur image, the image registration is not performed and the image is forcibly terminated.

  In the present embodiment, since the image recognition process is performed using the storage medium 13 of FIG. 1, it can be executed without worrying about the capacity when performing a large capacity process such as image recognition. For users who have several telephone terminals, it is possible to easily cope with the anti-voyeurism function by replacing the storage medium.

  FIG. 6 is an operation flowchart showing the fifth embodiment of the present invention.

  In the present embodiment, in the third or fourth embodiment, before the captured image is recognized, whether or not it is a voyeur is determined based on the distance between the camera (lens) at the time of shooting and the subject. Judging by measuring the tilt of the mobile phone terminal (the direction of the lens), for those that were determined to be voyeurism, without performing image recognition processing on the captured image, by forcibly terminating without performing image registration, It is intended to prevent voyeurism and reduce the image recognition processing burden. The operation of this embodiment will be described below with reference to FIG.

  When camera shooting is activated (step S1), the voyeur surveillance function of the voyeurism prevention function unit 11 is activated (step S2). When the user presses the shooting button (step S3), a shooting operation is performed, and at that time, a shutter sound similar to the conventional technology is generated (step S4).

  In the voyeur surveillance function, the distance between the camera (lens) and the subject at the time of shooting and the tilt (the direction of the lens) of the mobile phone terminal at the time of shooting are measured. In the case of voyeur photography, the distance between the subject and the lens when the shooting button is pressed is close, and shooting is performed at an angle that is difficult to shoot. And the range of inclination is set as a criterion in advance, and it is determined whether or not it is voyeurism.

  When the measured inclination of the mobile phone terminal and the distance to the subject are respectively compared with the determination criteria and it is determined that the camera is a voyeur (step S5), the shooting mode is forcibly terminated and the shot image is taken. Prohibit registration. For those that are not determined as voyeurism, the process proceeds to the registration operation of the third or fourth embodiment.

  In this embodiment, instead of providing a new parameter for preventing voyeurism, two parameters of distance and inclination are measured in the conventional shooting and used as a judgment criterion. In addition, since it is impossible to forcibly register an image that has been determined to be voyeurism, the image recognition processing burden in the subsequent registration operation can be reduced, which is an appropriate prevention measure.

  In the present embodiment, the voyeur surveillance function of the voyeurism prevention function unit 11 is combined with the third or fourth embodiment, but may be combined with the first or second embodiment. Furthermore, it is also possible to combine appropriate embodiments among the first to fifth embodiments.
