Description

  The present invention relates to an imaging device, a transmitter, a transmission control device, and an imaging control system.

  In recent years, an imaging device such as a digital camera, a portable terminal with an imaging function, and the like are rapidly spreading because they can easily capture an image of a subject desired by a user.

By the way, the downsizing of imaging devices and portable terminals with imaging functions is progressing, and cases of using them for the purpose of voyeurism are increasing in trains, changing rooms, and the like. Therefore, an imaging device has been developed that detects a voyeurism prevention signal generated from a voyeurism prevention information generation device owned by the subject and turns off the power of the camera sensor and the digital signal processing unit based on the detected voyeurism prevention signal. Thus, the imaging by the imaging apparatus is limited (for example, see Patent Document 1).

As illustrated in FIG. 1, the voyeurism prevention system 100 includes an imaging device 1 that is used when a subject S is voyeurized, a transmitter 2 that is held (mounted) by the subject S, and the risk of voyeurism by the imaging device 1. And a transmission control device 3 for controlling the transmission of the preventive operation instruction data D from the transmitter 2 for preventing the sneak shot of the subject S by the imaging device 1. Yes.

The transmission control device 3 is installed as a voyeurizing danger area R, for example, in a transport means for transporting people such as trains or buses in a group, in a toilet or in a changing room.
Below, the transmission control apparatus 3 is demonstrated in detail with reference to FIG. Here, FIG. 2 is a block diagram showing a main configuration of the transmission control device 3.

  As shown in FIG. 2, the transmission control device 3 includes an area designating unit 31 for designating a voyeurism risk area R, an area signal transmission unit 32 for transmitting an area signal W in the voyeurism danger area R, and a time measuring unit 33. A RAM 34, a ROM 35, a CPU 36, and a power switch 37. These units are connected by a bus X.

  The area designating unit 31 has an operation unit such as various switches operated by the user, for example, and designates a voyeurizing danger area R such as a train, a bus, a toilet, and a changing room based on the operation of the operation unit by the user. Is to do. In addition, when the voyeurism danger area R is designated by the area designating unit 31, a predetermined signal relating to the voyeurism danger area R is output to the CPU 36.

The area signal transmitter 32 is configured to transmit the area signal W at a signal level that reaches at least the entire inside of the voyeurism danger area R specified by the area specifying unit 31.
The area signal transmitter 32 may be configured to always transmit the area signal W, or may be configured to transmit at a predetermined timing.

  A RAM (Random Access Memory) 34 is, for example, a volatile semiconductor memory, and constitutes a work area (not shown) for various programs executed by the CPU 36.

A ROM (Read Only Memory) 35 is, for example, a read-only memory, and stores an area signal generation program 35a, a transmission time specifying program 35b, a signal transmission control program 35c, and the like.
In addition, the ROM 35 outputs a signal from the transmitter 2 of a voyeurism danger area R such as a train, a toilet, and a changing room, and prevention operation instruction data D for instructing execution of a predetermined voyeurism prevention operation (described later) by the imaging device 1. An area output level table T associated with levels is stored. Specifically, in the area output level table T, for example, in the train as the voyeurism danger area R, voyeurism from a short distance can be considered, so the signal output of the prevention operation instruction data D from the transmitter 2 is possible. The level is weak, and in the toilets and changing rooms, the signal output level of the prevention operation instruction data D is specified to be strong in consideration of voyeurism from a long distance.

A CPU (Central Processing Unit) 36 reads out various application programs related to various functions as the transmission control device 3 stored in the ROM 35, develops them in the work area of the RAM 34, and executes various processes according to the programs.
Specifically, according to the area signal generation program 35a, the CPU 36 transmits transmission instruction information for instructing transmission of the prevention operation instruction data D from the transmitter 2 and transmission prohibition instruction information for instructing prohibition of transmission of the prevention operation instruction data D. Of these, the area signal W including either one is generated. At this time, the CPU 36 is based on the transmission time data relating to the time at which the area signal transmitting unit 32 transmits the area signal W, which is output and input from the time measuring unit 33 according to the transmission time specifying program 35b as the transmission time specifying unit. The area including the transmission instruction information or the transmission prohibition instruction information is specified based on the transmission time of the area signal W specified from the area signal W. A signal W is generated. That is, for example, in the train as the voyeurism danger area R designated by the area designation unit 31, the CPU 36 displays the area signal W including the transmission instruction information in a time zone where the risk of voyeurism is high, such as at rush hours or at night. In other time zones, the area signal W including the transmission prohibition instruction information is generated.

  Further, when generating the area signal W including the transmission instruction information, the CPU 36 sets the signal output level from the transmitter 2 of the prevention operation instruction data D corresponding to the voyeurism danger area R designated by the area designation unit 31. An area signal obtained from the area output level table T stored in the ROM 35 and including the output level area instruction information in which the signal output level from the transmitter 2 of the prevention operation instruction data D is defined according to the voyeurism danger area R W is generated.

  Further, the CPU 36 causes the area signal transmission unit 32 to transmit an area signal W including any one of the generated transmission instruction information or transmission prohibition instruction information according to the signal transmission control program 35c as a signal transmission control means.

  The power switch 37 outputs an instruction signal for turning on or off the power supply of the transmission control device 3 based on a user operation.

  Next, the transmitter 2 will be described in detail with reference to FIG. Here, FIG. 3 is a block diagram showing a main configuration of the transmitter 2.

  As shown in FIG. 3, the transmitter 2 includes an area signal receiving unit 21 that receives an area signal W transmitted from the transmission control device 3, an instruction information transmitting unit 22 that transmits prevention operation instruction data D, and instruction information.

The display device 11f is configured by, for example, an LCD (Liquid Crystal Display), an EL (Electro Luminescence) display, or the like.

The A / D conversion circuit 12 converts the input analog signal output from the image sensor 11 c into a digital signal, and outputs the converted digital image signal to the image memory 13.
The image memory 13 temporarily stores the digital image signal input via the A / D conversion circuit 12.

The instruction information receiving unit 15 receives the prevention operation instruction data D transmitted from the instruction information transmitting unit 22 of the transmitter 2. Specifically, the instruction information receiving unit 15, for example, the prevention operation instruction data D including the sound generation instruction information, the prevention operation instruction data D including the resolution reduction instruction information, the prevention operation instruction data D including the display instruction information, The prevention operation instruction data D including the imaging stop instruction information is received.
Here, reception of the prevention operation instruction data D by the instruction information receiving unit 15 is always performed in a state where the power of the imaging apparatus 1 is turned on based on the operation of the power switch 19 by the user. It may be good or may be configured to be performed in a predetermined cycle. In addition, in the state where the imaging apparatus 1 starts the imaging operation based on the power-on timing of the imaging apparatus 1 based on the operation of the power switch 19 by the user or the half-press operation of the release switch 1a by the user, for example. The information receiving unit 15 may receive the prevention operation instruction data D.
In addition, the instruction information receiving unit 15 determines the strength of the signal level of the received prevention operation instruction data D as a strength determination unit.
The prevention operation instruction data D received by the instruction information receiving unit 15 is output to the RAM 16.

  The RAM 16 constitutes a storage area for temporarily storing the prevention operation instruction data D received by the instruction information receiving unit 15, a work area for various programs executed by the CPU 18, and the like.

  The ROM 17 is composed of, for example, a rewritable semiconductor memory and the like, and stores application programs for various processes as a digital camera executed by the CPU 18, data used for various operations, and the like. Specifically, the ROM 17 stores an operation control program 17a, an operation specifying program 17b, and the like.

The CPU 18 reads out various application programs related to various functions as a digital camera stored in the ROM 17, develops them in the work area of the RAM 16, and executes various processes such as an imaging process according to the programs.
Specifically, the CPU 18 operates as an operation control unit according to the operation control program 17a, based on the prevention operation instruction data D received by the instruction information receiving unit 15, and restricted or executed by the imaging unit 11 or the like. To control. That is, as a voyeurism prevention operation, the CPU 18 forcibly causes the speaker e1 to sound based on the sound generation instruction information included in the prevention operation instruction data D in a state where the speaker e1 is set to non-sound by the changeover switch e2. An image signal output from the image sensor 11c based on the drive reduction instruction information included in the prevention operation instruction data D or the drive reduction of the drive motor 11b based on the drive restriction instruction information included in the prevention operation instruction data D. The display device 11f displays a message warning the voyeur shooting of the subject S by the imaging unit 11 based on the display instruction information included in the prevention operation instruction data D, or is included in the prevention operation instruction data D. The imaging of the subject S by the imaging unit 11 is stopped based on the imaging stop instruction information.

  For example, when the prevention operation instruction data D includes information for instructing a plurality of voyeurism prevention operations, the CPU 18 serves as an operation specifying unit according to the operation specifying program 17b to prevent the operation by the instruction information receiving unit 15. Based on the determination result of the signal level of the instruction data D, the voyeurism prevention operation to be performed by the imaging unit 11 or the like is specified. Specifically, for example, when the signal level of the prevention operation instruction data D received by the instruction information receiving unit 15 is strong, that is, when the imaging apparatus 1 exists at a short distance from the subject S, the CPU 18 performs imaging. While the imaging of the subject S by the unit 11 is stopped or the resolution of the image signal output from the imaging device 11c is reduced, the signal level of the prevention operation instruction data D received by the instruction information receiving unit 15 is weak In this case, that is, when the imaging apparatus 1 exists at a long distance from the subject S, the driving of the drive motor 11b that moves the imaging lens 11a in the optical axis direction is limited.

The release switch 1a outputs an instruction signal instructing the CPU 18 to start an imaging operation based on a user operation. Here, when the output instruction signal is input to the CPU 18, the CPU 18 can drive a shutter device (not shown) to perform imaging.

  The power switch 19 outputs an instruction signal for turning on or off the power of the imaging apparatus 1 based on a user operation.

Next, voyeurism prevention processing by the voyeurism prevention system 100 having the above-described configuration will be described with reference to FIGS. 5 and 6.
Here, FIG. 5 is a flowchart illustrating an example of an operation related to the voyeurism prevention process by the voyeurism prevention system 100, and FIG. 6 is a flowchart illustrating an example of an operation related to the transmission control process by the transmitter 2 in the voyeurism prevention process. is there.

  As shown in FIG. 5, first, the transmission control device 3 is installed in a predetermined area by the user, and the voyeurizing danger area R corresponding to the installed area is designated by the area designating unit 31 (step S1).

  Next, the CPU 36 of the transmission control device 3 generates an area signal W including any one of the transmission instruction information and the transmission prohibition instruction information in accordance with the area signal generation program 35a read from the ROM 35 (step S2). Specifically, the CPU 36 reads the transmission time specifying program 35b from the ROM 35 and expands it in the RAM 34, and in accordance with the transmission time specifying program 35b, the area signal transmission is performed based on the transmission time data output from and input from the time measuring unit 33. The transmission time of the area signal W from the unit 32 is specified, and the area signal W including any one of the transmission instruction information or the transmission prohibition instruction information is generated based on the transmission time of the specified area signal W. It is like that. Thereby, for example, when the inside of the train is designated as the voyeurism risk area R by the area designation unit 31, the CPU 36 includes the area including the transmission instruction information in a time zone where the risk of voyeurism is high such as at rush hours or at night. The signal W is generated, and the area signal W including the transmission prohibition instruction information is generated in other time zones.

  Further, when generating the area signal W including the transmission instruction information, the CPU 36 sets the signal output level of the prevention operation instruction data D from the transmitter 2 according to the voyeurism danger area R designated by the area designation unit 31. Then, an area signal W that is obtained from the area output level table T of the ROM 35 and that includes output level area instruction information whose signal output level is defined according to the voyeurism danger area R is generated.

  Next, the CPU 36 reads out the signal transmission control program 35c from the ROM 35 and develops it in the RAM 34. The CPU 36 controls the area signal transmission unit 32 according to the signal transmission control program 35c, and generates the generated transmission instruction information or transmission prohibition instruction information. The area signal W including any one of them is transmitted (step S3).

Then, the subject S holding the transmitter 2 enters the voyeurizing danger area R, the area signal receiving unit 21 of the transmitter 2 receives the area signal W (step S4), and based on the reception of the area signal W, Under the control of the CPU 26, a transmission control process of the prevention operation instruction data D from the instruction information transmission unit 22 is executed (step S5).
In the following, the transmission control process executed under the control of the CPU 26 will be described in detail with reference to FIG.

  As shown in FIG. 6, first, the CPU 26 specifies the transmission mode of the prevention operation instruction data D set by the mode setting unit 23 based on the instruction signal output from the mode setting unit 23 (step S51). ). Here, when the transmission mode of the preventive operation instruction data D is set to the manual mode, the CPU 26 executes the processing after step S52, while when it is set to the automatic mode, the processing after step S53. Execute.

<Auto mode>
When the transmission mode of the prevention operation instruction data D is set to the automatic mode (step S53), the CPU 26 determines that the transmitter 2 is in the voyeurism danger area R before the area signal W is received by the area signal reception unit 21, that is, in the voyeurism danger area R. In the nonexistent state, the instruction information transmission unit 22 is controlled not to transmit the prevention operation instruction data D (step S531).

Then, for example, the CPU 26 reads out the information content determination program 25a from the ROM 25 at a predetermined timing and develops the information content determination program 25a in the RAM 24. The instruction information is transmitted to the area signal W received by the area signal receiving unit 21 according to the information content determination program 25a. It is determined whether or not transmission instruction information for instructing transmission of the prevention operation instruction data D from the unit 22 is included (step S532).
If the CPU 26 determines that the area signal W includes the transmission instruction information (step S532; Yes), the CPU 26 reads the operation instruction data generation program 25b from the ROM 25, expands it in the RAM 24, and this operation instruction data generation program. In accordance with 25b, predetermined prevention operation instruction data D is generated. Specifically, the CPU 26, as the prevention operation instruction data D, includes, for example, information including sound generation instruction information, information including drive restriction instruction information, data including resolution reduction instruction information, data including display instruction information, The data including at least one of the information including the imaging stop instruction information is generated.

  Then, the CPU 26 reads the transmitter control program 25c from the ROM 25 and expands it in the RAM 24. The CPU 26 generates the preventive operation instruction data D from the instruction information transmitter 22 based on the transmission instruction information according to the transmitter control program 25c. (Step S533). At this time, the CPU 26 reads out the output level variable program 25d from the ROM 25 and develops it in the RAM 24. Based on the output level area instruction information included in the area signal W according to the output level variable program 25d, the preventive operation instruction data D is read. The instruction level is transmitted from the instruction information transmission unit 22 by changing the output level.

  If CPU 26 determines in step S532 that no transmission instruction information is included in area signal W (step S532; No), it proceeds to step S531 and transmits instruction information that does not cause prevention operation instruction data D to be transmitted. The control state of the unit 22 is maintained.

<Manual mode>
When the transmission mode of the prevention operation instruction data D is the manual mode (step S52), and the transmission control of the prevention operation instruction data D by the CPU 26 is set to the OFF state (manual OFF) (step S521), the CPU 26 detects the risk of voyeurism. Even if the transmitter 2 exists in the area R, the prevention operation instruction data D is not transmitted without controlling the instruction information transmission unit 22.
On the other hand, when the transmission mode of the prevention operation instruction data D is the manual mode (step S52) and the transmission control of the prevention operation instruction data D by the CPU 26 is set to the ON state (manual ON) (step S522), the CPU 26 First, the instruction information transmission unit 22 is controlled not to transmit the prevention operation instruction data D (step S523).

Thereafter, for example, at a predetermined timing, the CPU 26 reads an area signal reception determination program (not shown) from the ROM 25 and develops it in the RAM 24, and the area signal reception unit 21 causes the instruction information transmission unit 22 to follow the area signal reception determination program. It is determined whether or not the area signal W including the transmission prohibition instruction information for instructing the prohibition of transmission of the preventive operation instruction data D is received (step S524). If the CPU 26 determines that the area signal W including the transmission prohibition instruction information has not been received (step S524; No), the CPU 26 receives predetermined prevention operation instruction data D according to the operation instruction data generation program 25b read from the ROM 25. Generate.
Note that the generated prevention operation instruction data D is the same as that generated in the automatic mode described above.

Then, the CPU 26 generates and transmits the prevention operation instruction data D from the instruction information transmitter 22 in accordance with the transmitter control program 25c read from the ROM 25 (step S525).
Thus, the transmitter 2 can be manually operated even in a place where the transmission control device 3 is not installed, that is, a place where the area signal W instructing transmission of the prevention operation instruction data D from the transmitter 2 is not transmitted. By setting the mode, it is possible to transmit the prevention operation instruction data D by the transmitter 2 alone, and to prevent the imaging device 1 from photographing the subject S.
At this time, the CPU 26 varies the output level of the prevention operation instruction data D based on the output level area instruction information included in the area signal W in accordance with the output level variable program 25d read from the ROM 25, as in the automatic mode described above. Thus, the instruction information transmission unit 22 transmits the information.

On the other hand, if the CPU 26 determines in step S524 that the area signal W including the transmission prohibition instruction information is received (step S524; Yes), the process proceeds to step S523, and the prevention operation instruction data D is received. The instruction information transmitting unit 22 is controlled so as not to transmit.
Thereby, for example, in places where it would be annoying to the surrounding people when sounding when shooting in a movie theater etc., it is not appropriate to force the sound from the speaker as a voyeurism prevention operation, Even when the user who is the subject S has mistakenly set the transmitter 2 to the manual ON mode, the area information W including the transmission prohibition instruction information is received by the instruction information receiving unit 15 of the imaging apparatus 1. As a result, the voyeurism prevention operation is not executed by the transmitter 2. Therefore, for example, the imaging device 1 used for purposes other than the voyeur of the subject S in the voyeur danger area R is not allowed to perform the voyeurism prevention operation, and the subject S can be appropriately limited in imaging. .

In the transmission control process described above, the prevention operation instruction data D is transmitted from the instruction information transmission unit 22 (step S6), and the imaging apparatus 1 that has entered the range where the prevention operation instruction data D reaches, that is, the voyeurism prevention area R1. When received by the instruction information receiving unit 15 at a predetermined timing (step S7), based on the prevention operation instruction data D, the CPU 18 of the imaging device 1 reads the operation control program 17a from the ROM 17 and develops it in the RAM 16, In accordance with the operation control program 17a, the image capturing unit 11 is caused to perform a voyeurism prevention operation (step S8).
Specifically, the CPU 18 forcibly generates sound from the speaker e1 based on the sound generation instruction information included in the prevention operation instruction data D in a state where the speaker e1 is set to non-sound by the changeover switch e2 as a voyeurism prevention operation. Or, based on drive restriction instruction information included in the prevention operation instruction data D, restricts driving of the drive motor 11b, or is output from the image sensor 11c based on resolution reduction instruction information included in the prevention operation instruction data D. The display signal 11f is displayed on the display device 11f on the basis of the display instruction information included in the prevention operation instruction data D, or the prevention operation instruction data D is displayed. The imaging unit 11 stops imaging of the subject S based on the imaging cancellation instruction information included in.

  In addition, the instruction information receiving unit 15 determines the strength of the signal level of the prevention operation instruction data D when the prevention operation instruction data D is received. For example, when the prevention operation instruction data D includes information for instructing a plurality of voyeurism prevention operations, the CPU 18 reads the operation specifying program 17b from the ROM 17 and expands it in the RAM 16, and this operation specifying program 17b. Accordingly, based on the determination result of the signal level of the prevention operation instruction data D by the instruction information receiving unit 15, the voyeurism prevention operation to be performed by the imaging unit 11 is specified.

As described above, according to the voyeurism prevention system 100, the area signal receiving unit 21 of the transmitter 2 receives the area signal W transmitted from the area signal transmitting unit 32 of the transmission control device 3 in the voyeurizing danger area R. Based on this, transmission of the prevention operation instruction data D related to the instruction of the voyeurism prevention operation by the imaging device 1 from the instruction information transmission unit 22 of the transmitter 2 is controlled. And the imaging device 1 makes the imaging part 11 etc. perform a sneak shot prevention operation | movement based on receiving the transmitted prevention operation instruction data in the instruction information receiving part 15. FIG.
Specifically, the imaging device 1 may, for example, forcibly cause the sound generation unit 11e to generate a sound even when the sound generation unit 11e is set to non-sound during the voyeur shooting of the subject S as a voyeurism prevention operation. Then, by moving the imaging lens 11a in the optical axis direction to enlarge the subject S to be photographed, to limit the drive of the drive motor 11b for performing focus adjustment or the like, or to take an image when the subject S is voyeurized. The resolution of the image signal output from the element 11c is reduced, a warning message is displayed on the display device 11f when the subject S is voyeurized, or the imaging of the subject S by the imaging unit 11 is stopped.
In this way, in the voyeurism prevention area R1 where the prevention operation instruction data D arrives within the voyeurism danger area R, the imaging device 1 is caused to execute the voyeurism prevention operation, and outside the prevention operation area R1, the voyeur of the subject S The voyeurism prevention operation is not executed for the imaging apparatus used for purposes other than the above. Therefore, it is possible to appropriately limit the imaging of the subject with respect to the imaging apparatus 1.

  In the state where the transmitter 2 is set to the automatic mode, the prevention operation instruction data D related to the instruction of the voyeurism prevention operation by the imaging device 1 is transmitted, and the area signal W including the transmission instruction information is received by the area signal reception unit 21. If the transmission instruction information is not included in the area signal W, the transmission of the prevention operation instruction data D can be prohibited. Can be done.

  Further, the output level of the prevention operation instruction data D from the instruction information transmitting unit 22 included in the area signal is transmitted into the voyeurism risk area R based on the output level information defined according to the voyeurism danger area R. Since the output level of the prevention operation instruction data D is varied, the size of the voyeurism prevention area R1 in which the sneak shot of the subject S by the imaging device 1 is restricted according to the voyeur danger area R from which the prevention operation instruction data D is transmitted. Can be adjusted.

  Further, the transmission control device 3 transmits the area signal W including either one of the transmission instruction information or the transmission prohibition instruction information from the area signal transmission unit 32 based on the transmission time of the area signal. Restricting voyeurism can be performed more appropriately according to time as well as location. That is, it is possible to designate a time during which the subject S has a high risk of voyeurism and cause the imaging device 1 to execute the voyeurism prevention operation of the subject within that time, and at other times the subject device S By preventing the prevention operation from being executed, the use of the imaging apparatus 1 for purposes other than the voyeur shooting of the subject S is not obstructed.

[Second Embodiment]

Then, the CPU 26 of the transmitter 102 stores in the ROM 25 as a reception time specifying means based on the reception time data relating to the time when the area signal W is received by the area signal reception unit 21, which is output and input from the time measuring unit 28. The reception time of the area signal W is specified according to the stored reception time specifying program 25e.
Further, the CPU 26 varies the output level of the prevention operation instruction data D based on the reception time of the specified area signal W as output level varying means.

  Therefore, according to the voyeurism prevention system of the second embodiment, the output level of the prevention operation instruction data D is varied based on the reception time of the area signal W by the transmitter 102. Depending on the time, it is possible to adjust the size of the sneak shot prevention area R1 in which the sneak shot of the subject S by the imaging device 1 is restricted. In other words, in the train as the voyeurism danger area R, for example, the voyeurism prevention area R1 is reduced in size in a time zone where the danger of voyeurism from a short distance such as during rush hours is high, that is, transmission is performed. The signal output level of the preventive operation instruction data D from the machine 102 is weak, and the risk of voyeur photography from a relatively long distance increases during times other than rush hours. The output level of the prevention operation instruction data D is varied so as to increase, that is, the signal output level of the prevention operation instruction data D increases. Thereby, both the prevention of the sneak shot of the subject S by the imaging device 1 and the imaging limitation for the imaging device used for purposes other than the voyeurism can be properly achieved.
