DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a proof image photographing storage device and a proof image photographing storage system, and more particularly, to a proof image photographing storage device and a taxi, a hire driver or the like in a commercial vehicle having no passengers other than a driver and a passenger. The present invention relates to a proof image photographing storage device and a proof image photographing storage system suitable for suppressing a robbery or a killing case and obtaining an proof image.

[0002]

2. Description of the Related Art In recent years, it is not uncommon for burglary cases and killings to occur in commercial vehicles such as taxis and hire vehicles. Especially during the year-end party season and the welcome and farewell party season, passengers rampage and injure the driver with the help of alcohol drunk momentum, In some cases, it can lead to killings.

[0003] In order to prevent such a burglary case in a commercial vehicle, for example, a transparent acrylic plate is installed at the boundary between the driver's seat and the passenger's seat, so that the passenger cannot easily reach the driver. In some cases.

However, since the fare is paid, the driver's seat and the passenger's seat cannot be completely shielded by the transparent acrylic plate. Since the service is customer service, the intention to block the vehicle with the transparent acrylic plate is clearly stated by the passenger. There is a sense of resistance to tell. In addition, since the inside of the car is closed and there is no third party other than the driver and the passenger, it is not easy to prove a burglary case or a killing case that occurs in such a situation.

On the other hand, as an invention intended for crime prevention in a car, Japanese Unexamined Patent Application Publication No. Hei 11-240422 discloses a security device with a monitor for safe driving of a car and a television. According to the present invention, a security-dedicated micro camera is installed above the driver's seat and the rear seat in an automobile,

According to the invention, it is possible to solve a trouble such as an accident by recording the inside of the vehicle with a micro camera during traveling, and to prevent a mischief such as a scratch or a puncture during parking.

[0007]

However, in the above-described conventional security device with a safe driving monitor for a vehicle, the micro camera is installed above the driver's seat and the rear seat, so that it is applied to a commercial vehicle. However, it was not possible to shoot a video that could confirm the passengers at the time, and the reliability as a proof video was lacking.

[0008] Further, since the micro-camera is designed to record a moving image, its specification is inferior to that of a still image, and the value of evidence is low. In addition, when shooting a moving image, there is a possibility that a necessary video cannot be shot when necessary because of a limitation in a shooting time. If the driver starts and stops the recording to capture only the necessary images, it is strict to force the driver to always determine the operation, which causes trouble in driving.

Further, in a conventional security device with a safe driving monitor and a television, since the image of the passenger is recorded without performing any processing, it cannot be said that the privacy of the passenger can be ensured. It was not feasible to mount it on a car.

SUMMARY OF THE INVENTION The present invention has been made to solve at least one of the above problems, and it is possible to securely protect the privacy of passengers and make it difficult to obtain a witness testimony from a third party.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an evidence video image capturing and storing apparatus and an evidence video image capturing and storing system according to the present invention.

As shown in FIGS. 1 and 2, a proof image photographing storage device 1a according to a first embodiment of the present invention is a taxi in which only a driver and a passenger have no passengers on the way other than those involved. The camera 3 is mounted on a commercial vehicle 2 such as a car or a car, and mainly receives a camera 3 for photographing a passenger, switches 9 and 12 for outputting a signal for starting photographing by the camera 3, and a photographing start signal. And a video recording device that captures a passenger's video and stores it after performing a random process.

More specifically, the camera 3 for photographing passengers is installed at a position where passengers can be photographed. In the present embodiment, in consideration of the fact that a passenger in the rear seat can be photographed from the front, a small C
The CD camera 3 is fixed.

As a switch for outputting a photographing start signal, a relay switch 9 having an automatic switch function is attached to the switch 8 of the passenger compartment door 7. For this reason, when the driver closes the switchgear 8 of the cabin door 7, the photographing start signal is transmitted in conjunction with the closing operation to the relay switch 9.
Is output from For example, the signal output timing may be such that a photographing start signal is output when the driver performs an operation of closing the switchgear 8, or the relay switch 9 is connected to a cylinder or the like (not shown) of the passenger compartment door 7. When the cabin door 7 is closed and the cabin door 7 is closed, the relay switch 9 may react to output a shooting start signal.

On the other hand, a manual switch 12 is provided on the left side of the driver's seat 10 so that a photographing start signal is output by an arbitrary switch operation of the driver.

The video recording device is arranged below the driver's seat so as not to hinder driving, and is mainly composed of control means 13 and storage means 14. Control means 1
Reference numeral 3 denotes a photographing control unit 15 that performs control for photographing a passenger.
A random processing control unit 16 for performing random processing on photographed video data, and a cyclic overwriting control unit 17 for controlling to cyclically overwrite a predetermined number or more of video data. The storage unit 14 includes a ROM 18 storing various programs and a RAM storing data and the like.
19, a removable storage medium 20 and a disk drive 21 of the storage medium 20.

More specifically, the photographing control unit 15 receives a photographing start signal from the relay switch 9 or the manual switch 12 and outputs a passenger image photographing instruction to the camera 3 so that the photographed image data is transferred to the work area. Is written in the RAM 19 as a memory. Here, the video data is preferably a still image rather than a moving image. This is because a moving image is inferior in detail to a still image. In particular, taking into account the shooting in a dark environment such as in-vehicle shooting or night shooting as in the present invention, still images are far superior in terms of investigation clues and value as evidence. In addition, in the case of moving images, the time required for shooting is severe and the necessary scenes may be missed when necessary. Still images are more preferable in consideration of performance and driving safety.

Further, the random processing control section 16 has a RAM 19
From the passenger data, subjecting each component data constituting the video data to a random processing according to a predetermined random processing program,
It is stored in a storage medium 20 such as RW. The image data that has been subjected to the random processing is such that a visible image cannot be obtained unless a dedicated playback device is used. In this way, even if the storage medium 20 on which the image data is recorded leaks out, even if it is reproduced with ordinary equipment, it does not become a visible image and the privacy of the passenger can be protected.

In the random processing, each component data of the image data is randomized. That is, the pixel positions composing the image are disordered, the color tone is disordered such as switching between green and red, and the lightness is disordered such as switching between light and dark.

For example, a general method for pixel position randomization will be described. Assume that the space of the original image is S, the space after the random processing is S ', and that S⊆S' is satisfied.

In order to map the image of each point in the space S to the space S ', first, the coordinates (x,
Formula F (x, y) for calculating coordinates (x ', y') of space S 'from y) is created. However, the formula F must be a function that makes different points in the space S correspond to different points in the space S ′. That is, if x or y is different, x '
The function must be such that at least one of y 'has a different value.

In the case of S⊆S ′, there are any number of functions F, and in the case of S = S ′, the point of S and the point of S ′ have a one-to-one correspondence, and special consideration is required. unnecessary. S
In the case of ⊂S ′, the value at that point is set to 0 for the point of S ′ that does not have a point corresponding to S in order to make the reverse processing easy to understand. In the case of S で は S ′, a plurality of points of S ′ may correspond to one point of S in the reverse process. In this case, the addition of the processing to the reverse processing is the addition of the value at each point or the ignoring of the value 0.

The image subjected to the random processing is subjected to the inverse processing, that is, the coordinates (x ', y') of the space S 'are converted to the coordinates (x', y ') of each point in the space S by the inverse function F' (x ', y') of the function F. , Y), the original video can be restored.

Next, the pixel position disorder processing will be described more specifically with reference to FIGS.

For convenience, it is assumed that the original video has 16 × 8 pixels as shown in FIG. As shown in FIG. 4, first, a process of exchanging each row of video data is performed as a first process, and then, a process of exchanging each column of video data is performed as a second process. Further, as a third process, a process of cyclically shifting the image data of each row formed by the first process and the second process to the right by the number of row numbers is performed. As a result of performing the above processing, it is possible to obtain a video that has been subjected to the random processing as shown in FIG.

Then, when restoring the video that has been subjected to the clutter processing, as shown in FIG. 6, the clutter processing of the first processing to the third processing may be performed in reverse order. That is, first, each line of the video data after the random processing is cyclically shifted to the left by the number of line numbers as a first process, and then, as a second process, each column is replaced as shown in FIG.
What is necessary is just to replace each line as a process. As described above, the random processing by the random processing controller 16 is executed.

Next, the above-described cyclic overwrite control unit 17 will be described. When the number of the passenger video data stored in the storage medium 20 exceeds a predetermined set number, Passenger video data beyond that is sequentially and cyclically overwritten. For example, if the number of stored passenger video data is set to 20, then 2
The first video data is written over the first video data, and the 22nd video data is repeatedly overwritten on the second video data.

Next, each component of the storage means 14 will be described.
Control programs such as a cyclic overwriting program and a random processing program are stored.

The RAM 19 is adapted to electrically store various types of data, and functions as a work area in which, for example, photographed passenger video data is written and the random processing is performed by the random processing controller 16. It has become.

The storage medium 20 magnetically stores the video data after the random processing via the disk drive 21. For example, the storage medium 20 corresponds to a CD-RW, MO, or the like. It can be transported to a dedicated regenerator.

The video recorder 4 is a commercial vehicle 2
Is connected directly to a battery (not shown), and this battery is used as a power source. As a result, the battery can be used even when the engine is stopped without fear of running out of the battery.

Next, the operation of the above-described evidence image photographing storage device 1a according to the first embodiment will be described with reference to FIG.

Evidence image photographing storage device 1 of the first embodiment
In a, when the driver confirms that the passenger has completely entered the commercial vehicle 2, the driver closes the switchgear 8 to open the passenger compartment door 7.
Close. At this time, in step 1, the relay switch 9 attached to the switch 8 is turned on. Alternatively, when the driver arbitrarily operates and turns on the manual switch 12 installed near the driver, the process proceeds to step 2 and the image capturing control unit 15 starts capturing the ON signal of the relay switch 9 or the manual switch 12. Recognize as a signal. Then, the process proceeds to step 3, in which the photographing control unit 15 starts photographing control for the CCD camera 3, and in step 4, the image data of the passenger photographed by the CCD camera 3 is stored in the RAM 1.
Record in 9. Next, proceeding to step 5, the random processing controller 16 immediately reads the video data from the RAM 19 and executes the random processing in accordance with a predetermined random processing program stored in the ROM 18.

Thereafter, the process proceeds to step 6, wherein when the video data after the random processing is stored in a recording medium such as a CD-RW, whether the number of video data already stored has reached a predetermined set number or not. The judgment is made by the target overwriting control unit 17, and if the predetermined number is not reached, the process proceeds to step 7, and if the predetermined number is reached, the process proceeds to step 8.

If the determination in step 6 is YES, that is, if the number of stored video data has not reached the set number, the process proceeds to step 7 where the random processing controller 16 stores the video data in the storage medium 20 as it is. Video data is sequentially recorded.

On the other hand, if the determination in step 6 is NO, that is, if the number of stored video data has reached the set number, the process proceeds to step 8 where the cyclic overwrite control unit 17 By controlling the drive 21, the storage medium 2
Overwrite recording is performed cyclically to 0. That is, the video data is automatically and sequentially overwritten on the video data recorded at the oldest date and time.

The storage medium 2 which can be removed in this way
In the event that a burglary case or a killing case occurs in the commercial vehicle 2 unexpectedly, the storage medium 20 is taken out, and a safe or secure service such as a police or taxi association is recorded. The video is played back by a dedicated player installed at the location, and is used as a clue and evidence for the investigation.

Therefore, according to the evidence image photographing storage device 1a of the first embodiment, when a burglary or a killing case occurs in a business vehicle 2 such as a taxi or a hire where it is difficult to obtain a witness testimony of a third party. In this way, it is possible to easily obtain a clue to the investigation, or to surely obtain the evidence video.

Further, by advertising in advance that such a video is to be taken, it is possible to effectively suppress a burglary or a killing case.

On the other hand, in the first embodiment of the present invention, it is not necessary to store the video data after the random processing and then store the appropriate number of video data, and then overwrite and record the oldest video data sequentially. Since the video data is automatically erased, it is possible to sufficiently secure privacy protection for passengers who are not involved in a burglary or the like, and the service reliability of the commercial vehicle 2 is not spoiled.

In the evidence image photographing storage device 1a of the first embodiment, since the image of the passenger is photographed in conjunction with the closing operation of the cabin door 7, the photographing is performed even when the passenger gets off. Will be. On the other hand, a fee calculation meter is connected to the video recording device 4, and signals such as empty vehicle, renting, surcharge, and payment are received from the fee calculation meter, and passenger getting on / off is determined. It is also possible to shoot an image only when a passenger gets on the vehicle. However, in consideration of the evidential value in the sense that a passenger has got off, the first embodiment is not used in the first embodiment.

The cyclic overwrite control unit 17 in the first embodiment described above determines whether the number of video data stored in the storage medium 20 has reached the overwrite set number in step 6 in FIG. However, without such a logical judgment, the video data stored in the earliest storage area should be deleted or overwritten as soon as the set number is exceeded. It may be. In this way, the control of the cyclic overwrite control unit 17 is simplified, and the probability of occurrence of a control error can be reduced.

Next, a description will be given of an example of an embodiment of the evidence video shooting and storage system 23 utilizing the second embodiment of the evidence video shooting and storage device 1b according to the present invention. The evidence video shooting storage system 23 of the present embodiment connects the evidence video shooting storage device 1b and the video management host computer 24 via a communication network 25 such as a mobile communication line.

It should be noted that, among the evidence video shooting and storage devices 1b constituting the evidence video shooting and storage system 23 of the present embodiment,

As shown in FIG. 8, the feature of the evidence video shooting and storage system 23 of this embodiment is that each business vehicle 2 is equipped with the evidence video shooting and storage device 1b of the second embodiment.
The video data that has been subjected to the clutter processing is transmitted to the video management host computer 24. That is, the video data is not stored in the storage medium 20 that can be taken out in the vehicle as in the evidence video shooting storage device 1a of the first embodiment, but the communication control unit 26 and the communication line A face 27 is provided. Then, the video data subjected to the clutter processing by the clutter processing control unit 16 is controlled by the communication control unit 26 and transmitted from a communication line interface 27 such as a communication antenna.

The video data transmitted from the communication line interface 27 is packet-communicated with the vehicle data specifying the vehicle via a mobile communication line 25 such as a portable telephone line, and is deployed at the police or a data management center. It is transmitted to the video management host computer 24. The video management host computer 24 is provided with a receiving unit 28 for receiving video data transmitted from each commercial vehicle 2, and the host-side recording control unit 29 receives the video data received by the receiving unit 28. The data is sequentially recorded in a predetermined memory area of the host-side storage unit 30.

A memory area is set in the host-side storage section 30 in such a manner that a storage medium 20 such as a hard disk is divided for each business vehicle 2 and a predetermined number of video data is stored as a file. It has become. When the number of recorded video data for each vehicle is equal to or greater than the set number, the further video data is
The host recording control section cyclically overwrites and records.

Although the video management host computer 24 can be equipped with the function of a dedicated playback device, it is possible to secure the privacy of passengers in consideration of the reliability.
It is preferable to manage them separately. In this case, the storage medium 20 and the disk drive 21 which can be taken out as needed are mounted on the video management host computer 24, and the storage medium 20 is inserted only when necessary, and Only the data may be read out and recorded.

Next, the operation of the evidence image photographing and storing system 23 of the present embodiment will be described with reference to FIG.

Alternatively, when the driver arbitrarily operates and turns on the manual switch 12 provided near the driver, the process proceeds to step 12, where the image capturing control unit 15 starts capturing an ON signal of the relay switch 9 or the manual switch 12. Recognize as a signal. Then, the process proceeds to step 13, where the photographing control unit 15 starts photographing control for the CCD camera 3, and proceeds to step 1.
At 4, the image data of the passenger photographed by the CCD camera 3 is recorded in the RAM 19. Next, the process proceeds to step 15, where the clutter processing control unit 16 immediately reads the video data from the RAM 19 and executes the clutter processing according to a predetermined clutter processing program recorded in the ROM 18.

Thereafter, the process proceeds to step 16, where the communication control unit 26 receives the video data after the random processing and transmits it from the communication line interface 27 to the video management host computer 24 via the mobile communication line 25. At this time, vehicle data that can specify the vehicle of the commercial vehicle 2 is also transmitted.

In step 17, the receiving section 28 of the video management host computer 24 receives the video data and the vehicle data transmitted via the mobile communication line 25, and proceeds to step 18.

In step 18, the host-side recording control unit 29 specifies the vehicle that has transmitted the video data based on the vehicle data, and when storing it in the host-side storage unit 30 in step 19, In the divided memory area, it is determined whether or not the number of already stored video data after the random processing has not reached a predetermined set number. If it is determined that the set number has not been reached, the process proceeds to step 20, and if it is determined that the set number has been reached, the process proceeds to step 21.

If the determination in step 19 is YES, that is, if the number of stored video data after the clutter processing has not reached the set number, the process proceeds to step 20 where the host-side recording control unit 29 Host-side storage unit 3
0 is sequentially recorded as video data.

On the other hand, if the determination in step 19 is NO, that is, if the number of stored video data after the random processing has reached the set number, the process proceeds to step 21 and the host-side recording control unit 29 performs automatic overwrite recording in a memory area of the host-side storage unit 30 cyclically. That is, the video data recorded at the oldest date and time is automatically overwritten and recorded sequentially.

As described above, in the image management host computer 24, the image data of the passenger transmitted from each business vehicle 2 is recorded, and the business vehicle 2
If a robbery case or a killing case occurs, the video data relating to the case is read from the host-side storage unit 30 and the video is reproduced by a dedicated player, and used as a clue or evidence for an investigation. ing.
