Description

  The present invention relates to a portable imaging device and a computer program that can prohibit imaging for the purpose of voyeurism.

Conventionally, portable imaging devices such as a portable still camera, a portable video camera, and a camera-equipped cellular phone device have been dramatically reduced in size and improved in portability by users. However, imaging devices having high portability have been abused for anti-social acts such as voyeurizing a woman's skirt from a low angle, for example, in a train, at home, on stairs, or on an escalator. In particular, in a camera-equipped mobile phone device having a communication function, captured image data can be immediately uploaded to the Internet and can be easily abused. In order to prevent such voyeurism, the conventional portable imaging device has been devised to emit a beep sound or flash light during imaging. However, such a device has not been able to produce a special effect due to noise or lighting around the voyeur site. In view of this, there has been further proposed an imaging apparatus that prohibits imaging when it is determined that the optical axis direction of the imaging lens is vertically upward (for example, Patent Document 1 or Patent Document 2).

  The power supply control unit 25 is connected to the battery 26, and controls supply and interruption of power stored in the battery 26. The battery 26 is connected to each hardware via a power supply line (not shown; the same applies hereinafter), and the power supply control unit 25 supplies power to each hardware via this power supply line. Further, the power supply control unit 25 performs a process of switching from the power-on (on) state to the power-off (off) state by cutting off the power supply through the power supply line.

  Next, attitude determination means executed by the control unit 10 will be described. FIG. 4 is a side view for explaining an angle θ between the optical axis direction and a predetermined direction.

The control unit 10 sets the vertical direction based on the gravity data of the earth detected by the acceleration sensor 27 or the geomagnetic data of the vertical direction detected by the geomagnetic sensor 28 when the predetermined direction is preset as the vertical direction. To do.
Further, the control unit 10 sets any one of the three-dimensional accelerations detected by the acceleration sensor 27 so as to be in the optical axis direction of the imaging lens 81, and is based on the three-dimensional acceleration data detected by the acceleration sensor 27. Thus, the optical axis direction of the imaging lens 81 is detected.

The control unit 10 calculates an angle θ between the detected optical axis direction and the set vertical direction. The control unit 10 reads the threshold value a for the angle θ stored in the storage unit 18 and determines whether or not the angle θ is equal to or smaller than the read threshold value a. When the control unit 10 determines that the angle θ is equal to or smaller than the threshold value a, the control unit 10 determines that the imaging lens 81 is directed substantially vertically upward, and determines that the mobile phone 1 is misused for voyeurism from a low angle. To do. The threshold value a is set and updated in advance such that a = view angle / 2 based on the view angle of the imaging lens 81, for example.
In the present embodiment, an example in which the angle θ is calculated between the optical axis direction and the vertical direction of the imaging lens 81 has been described. However, the present invention is not limited to this, and for example, the imaging lens You may make it calculate by angle (theta) between 81 and a horizontal direction. In this case, the control unit 10 determines whether or not the angle θ exceeds the threshold value a, and determines that the imaging lens 81 is directed substantially vertically upward when it is determined that the angle θ exceeds the threshold value a.

  Next, the prohibition zone determination means executed by the control unit 10 will be described. FIG. 5 is a schematic diagram for explaining the relationship between the current position and the prohibited area for imaging.

The control unit 10 determines its current position based on the coordinate data (x5, y5) or (x6, y6) of the mobile phone 1 detected by the GPS unit 29. In addition, the control unit 10 reads the coordinate data (x1, y1), (x2, y2), (x3, y3) and (x4, y4) that are the imaging prohibited areas stored in the storage unit 18. The coordinate data that becomes the imaging prohibited area is preset and updated.
The control unit 10 determines whether or not its current position is within the imaging prohibited area based on each coordinate data. For example, when the coordinate data of the mobile phone 1 is (x5, y5), the control unit 10 determines that its current position is an imaging prohibited area, and the coordinate data of the mobile phone 1 is (x6, y6). At some point, it is determined that its current position is not an imaging prohibited area.

  In the present embodiment, an example has been described in which coordinate data that is an imaging prohibited area is read from the storage unit 18 that stores the coordinate data. However, the present invention is not limited to this, and the control unit 10 determines that coordinate data (x1, y1), (x2, y2), (x3, y3), and (x3, y2) that are imaging prohibited areas from the outside at the time of determination. x4, y4) may be received, and the determination may be made based on the received coordinate data to be an imaging prohibited area.

  In addition, the control unit 10 does not acquire the coordinate data of the mobile phone 1 by the GPS unit 29, but receives a signal indicating that the imaging is prohibited from the outside at the time of determination. You may make it judge that it exists in a prohibited area. A signal indicating that imaging is prohibited is transmitted to the mobile phone 1 by a transmitting device (not shown; the same applies hereinafter) installed at a location where imaging should be prohibited. Thus, according to the present invention, even if the cellular phone 1 does not include the GPS unit 29, it can be determined whether or not it is an imaging prohibited area.

  Next, the moving speed detection means of the mobile phone 1 executed by the control unit 10 and the control process based on the detected moving speed will be described. FIG. 6 is a schematic diagram for explaining the moving speed of the current position.

The control unit 10 detects the moving speed of its current position based on the coordinate data (x5, y5), (x7, y7) and (x8, y8) of the mobile phone 1 sequentially detected by the GPS unit 29. The control unit 10 detects the moving speed of its current position by dividing the moving distance calculated based on a plurality of coordinate data by the time counted by a built-in timer (not shown; the same applies hereinafter).
The control unit 10 reads movement speed data that is stored in the storage unit 18 and should be prohibited from being imaged. The moving speed data that should be prohibited from being imaged is set and updated in advance in consideration of, for example, the operating speed of the escalator and the moving speed of the train.
The control unit 10 determines whether or not the calculated movement speed of the current position is within a range of movement speeds at which imaging should be prohibited. When the control unit 10 determines that the moving speed of its current position is within the range of the moving speed at which imaging is prohibited, the control unit 10 determines that the imaging location is within an escalator or a running train, and the mobile phone 1 Is determined to be misused for voyeurism.

  Next, the distance measuring unit to the subject executed by the control unit 10 and the control process based on the measured distance M to the subject will be described. FIG. 7 is a schematic diagram for explaining the distance M to the subject.

The control unit 10 causes the distance detection sensor 31 to detect the distance M to the subject. The control unit 10 reads the data of the distance n to the subject that should be prohibited from imaging, which is stored in the storage unit 18. The distance n to the subject to be prohibited from being imaged is set and updated in advance in consideration of the distance at which the mobile phone 1 is placed inside a woman's skirt and the underwear is easily taken close-up. For example, the control unit 10 determines whether or not the distance M to the subject is equal to or less than the distance n to the subject whose imaging is to be prohibited (see FIG. 7). When the control unit 10 determines that the distance M to the subject is equal to or less than the distance n to the subject to be imaged, the control unit 10 determines that the mobile phone 1 may be misused for voyeurism.
In the present embodiment, an example has been described in which it is determined whether or not the distance M to the subject is equal to or less than a preset distance n. However, the present invention is not limited to this, and for example, it may be determined whether or not the distance M to the subject is within a preset range of a short distance l to a long distance n. . When the distance to the subject is extremely close, it is easy to detect voyeurism. On the contrary, this is not imaging for the purpose of voyeurism. The present invention can be adjusted so that the original imaging function is not significantly impaired.

  Next, the face area detection unit of the subject executed by the control unit 10 and the control process according to the detection result will be described. FIG. 8 is a schematic diagram for explaining the detection of the face area of the subject.

  The control unit 10 reads the face area detection program stored in the storage unit 18. The read face area detection program causes the control unit 10 to execute the following algorithm. The control unit 10 outputs an image signal regarding the image of the subject to the specific area detector 132. The specific area detector 132 performs a band-pass filter process that can extract only a signal in a specific frequency band in the vertical direction on the received image signal (see FIG. 8A) or a band pass in the horizontal direction. Filter processing is performed (see FIG. 8B), and edge components are extracted from the image signal.

The specific area detector 132 performs pattern matching on the extracted edge components, and extracts characteristic parts such as eyes, nose, mouth, and ears. The specific area detector 132 performs a predetermined non-face condition filter process on the extracted characteristic part to extract the face area of the subject. Here, the non-face condition filter indicates an evaluation value for the detected characteristic part, and a case where the detected characteristic part does not satisfy the evaluation value is not a face region.
The control unit 10 determines whether or not the face area of the subject can be detected according to the result. If the control unit 10 determines that the face area of the subject cannot be detected, the control unit 10 determines that the mobile phone 1 may be misused for voyeurism inside the skirt.

  Next, the subject temperature measuring means executed by the control unit 10 and the control process based on the measured subject temperature will be described.

  The control unit 10 causes the temperature measurement sensor 23 to detect the temperature of the subject. The control unit 10 reads out data on the temperature of the subject that should be prohibited from being captured, which is stored in the storage unit 18. The temperature of the subject that should be prohibited from being imaged is set and updated in advance in consideration of, for example, the body temperature of a woman. For example, the control unit 10 determines whether or not the temperature of the subject is within the range of the temperature of the subject that should be prohibited from imaging. When the control unit 10 determines that the temperature of the subject is within the range of the temperature of the subject that should be prohibited from being imaged, the control unit 10 determines that the mobile phone 1 may be misused for voyeurism on a female image.

Example 1.
A procedure of control processing for controlling execution of imaging-related processing executed by the control unit 10 will be described. FIG. 9 is a flowchart illustrating the procedure of the control process for controlling the execution of the imaging related process according to the first embodiment.

  When the control unit 10 of the mobile phone 1 receives an instruction to exert an imaging-related function input by the user via the operation unit 5, by supplying power from the battery 26 according to the received instruction, The imaging processing unit 13 is activated (S101). The control unit 10 causes the acceleration sensor 27 to detect the optical axis direction of the imaging lens 81 (S102), causes the geomagnetic sensor 28 to detect the direction of gravity, and sets the vertical direction (S103). The control unit 10 calculates an angle θ between the optical axis direction and the vertical direction of the imaging lens 81 (S104), and reads the threshold value a stored in the storage unit 18.

  The control unit 10 compares the angle θ with the threshold value a, and determines whether the angle θ is equal to or smaller than the threshold value a (S105). As a result, if the control unit 10 determines that the angle θ exceeds the threshold value a (NO in S105), the control unit 10 determines that the image is not for voyeurism and performs imaging-related processing (S106). The control unit 10 causes the image data generator 134 to generate image data and stores the generated image data in the storage unit 18 in the execution of the imaging-related processing. The control unit 10 determines whether or not a stop instruction for the imaging processing unit 13 input by the user has been received via the operation unit 5 (S107), and determines that the stop instruction for the imaging processing unit 13 has not been received. (NO in S107), the process returns to step S102, and the control process is repeated.

  On the other hand, when the control unit 10 determines that an instruction to stop the imaging processing unit 13 has been received (YES in S107), the control unit 10 stops the imaging processing unit 13 and ends the control process.

  On the other hand, if the control unit 10 determines in step 105 that the angle θ is equal to or smaller than the threshold value a (YES in S105), the control unit 10 determines that the imaging lens 81 is directed vertically upward and The current position is detected (S108), and it is determined whether or not the detected current position is an imaging prohibited area (S109). As a result, if it is determined that the current position of the control unit 10 is not an imaging prohibited area (NO in S109), the control unit 10 determines that the imaging is not for voyeurism and performs imaging related processing (S106). The control unit 10 generates image data and stores it in the storage unit 18. When the control unit 10 determines whether or not the stop instruction of the imaging processing unit 13 input by the user is received via the operation unit 5 (S107), and determines that the stop instruction of the imaging processing unit 13 is not received (NO in S107), the process returns to step S102, and the control process is repeated.

  On the other hand, when the control unit 10 determines that an instruction to stop the imaging processing unit 13 has been received (YES in S107), the control unit 10 stops the imaging processing unit 13 and ends the control process.

  On the other hand, if the control unit 10 determines in step 109 that its current position is an imaging prohibited area (YES in S109), the control unit 10 determines that the imaging is for voyeurism and stops imaging-related processing (S110). The imaging processing unit 13 is stopped and the control process is terminated.

Example 2
In the first embodiment described above, an example has been described in which imaging prohibition is determined based on only the posture of the mobile phone 1 and the current position of the mobile phone 1. However, the present invention is not limited to this, and the moving speed of the mobile phone 1 may be added to the imaging prohibition condition. As a result, the present invention can determine whether or not the current position of the mobile phone 1 is in an escalator capable of voyeuring from a low angle, or a running train that is easy to voyeur from a low angle. 1 can be reliably prevented from being misused for voyeurism.
Therefore, in the second embodiment, an example will be described in which imaging prohibition is determined by further considering the moving speed of the mobile phone 1. FIG. 10 is a flowchart illustrating the procedure of the control process for controlling the execution of the imaging related process according to the second embodiment.

  When the control unit 10 of the mobile phone 1 receives an instruction to exert an imaging-related function input by the user via the operation unit 5, by supplying power from the battery 26 according to the received instruction, The imaging processing unit 13 is activated (S201). The control unit 10 causes the acceleration sensor 27 to detect the optical axis direction of the imaging lens 81 (S202), causes the geomagnetic sensor 28 to detect the direction of gravity, and sets the vertical direction (S203).
