Each pair of loop coils L ₁ , L ₂ and L ₃ , L ₄ constitutes a detection section of a vehicle detection device 3 that detects the entry of a vehicle. The vehicle detection device 3 outputs a detection signal when a vehicle enters an intersection at a speed higher than a predetermined speed. A signal information circuit 1 is provided in a traffic light (not shown) that is not provided near the O point, and signal information indicating what color the signal is displayed is extracted by the signal information circuit 1.

Signals from the vehicle detection device 3 and the signal information circuit 1 are input to the signal disregard determination circuit 2 . Based on such information, the determination circuit 2 determines whether the vehicle in question is a vehicle that ignored a traffic signal, and also sends a photographing command to a camera 5 and a television camera 8, which will be described in detail later, to the data display section 4. Provides data.

The data display section 4 has a clock circuit and always has current time data. The display function uses the consecutive number for each number of shots as the (number), and the date on which the photo was taken as the (date), the last two digits of the Western calendar,
The month and day can each be displayed as two-digit numbers.

Further, it is possible to display how many seconds have elapsed since the red light was turned on when the first photographing and the second photographing were performed, respectively, as the red light elapsed time.

(Red light elapsed time) column in the data section of Figure 3.
03.2 and 03.9 indicate that the first photograph was taken 3.2 seconds after the traffic light turned red, and the second photograph was taken 3.9 seconds after the traffic light turned red.

The display is performed by a group of 7-segment LED display elements and a display element showing a signal mark corresponding to the display of a traffic light.

The signal mark is used to confirm that the signal state was red when the first and second photography was performed.

The display of this data display section is controlled by a signal from the signal neglect determination circuit 2 shown in FIG.

In order to obtain the image for the sub-screen shown in FIG. 3, the video camera 8 is installed at the position indicated by O ₂ in FIG. 1, and a strobe light emitting unit 7 is provided in the vicinity thereof.

A video signal from the television camera 8 captured by the flash light emitting section 7 is transmitted to the monitor 9 via a cable connecting the television camera 8 and a monitor 9, which will be described later.

The monitor 9 side is equipped with an A-D converter that digitizes the video signal. is stored in field memory. This stored video is displayed on the monitor 9 as a one-field still image.

The camera 5 is capable of photographing, on the same film screen, the vehicle immediately after entering the vehicle, the vehicle after a certain period of time obtained by the video device, and the display contents of the data display section described above.

Fig. 4 shows the optical system of this camera, and Fig. 5 shows its external appearance. In FIG. 4, numeral 7 indicates one frame of the film shown in FIG.

In the space defined by the camera body 61, prism housing 60, and front plate 59 shown in FIG.
The prisms 51, 52, 53 shown in the figure are housed closely together. A prism 52 is a prism for the main screen imaged on the film 7 shown in FIG. 3, and a telephoto lens 55 is associated with this prism. The prism 51 is a prism for a sub-screen, and is associated with a lens 54. A monitor 9 is arranged in front of the lens 54.

Further, the above-mentioned strobe light emitting unit 7 for the video device is driven in synchronization with the imaging by the television camera 8 according to the second imaging command.

The operation of the apparatus having the above configuration will be explained with reference to each figure.

The camera 5 is in a state where the film is wound up after the previous shooting is completed and it is ready to take a photo. Suppose that a vehicle enters the intersection shown in Figure 1 by stepping on loop coils L ₁ and L ₂ after the traffic signal display turns red. When this speed exceeds a predetermined speed,
When the signal disregard determination circuit 2 issues the first photographing command, the shutter of the telephoto lens 55 of the camera 5 is activated, and the vehicle near the _P1 point (see FIG. The image is photographed under lighting. This is the photographing of the main screen shown in FIG. 4, and the front end side of the vehicle is photographed in a large size so that the driver inside the vehicle can be identified. Subsequently, a second photographing command is issued at a point that would have reached point _P2 in FIG. The sub-screen shown in FIG. 3 is photographed.

The data shutter 56 is operated at the same time as the main screen is photographed, and the data displayed on the data display section 4 is photographed by the time the sub-screen is photographed. Since the sub-screen is photographed by the television camera 8 using a relatively wide-angle lens, not only the vehicle but also the surroundings are recorded. Even if the vehicle does not go straight but tries to turn left or right, the entire vehicle is photographed.

As described in detail above, according to the device according to the present invention, images of the front of the vehicle immediately after the vehicle enters the vehicle and the rear of the vehicle after a certain period of time can be photographed on the same screen together with data related to that time. Shooting from the rear is especially effective for recording motorcycles with license plates on the rear of the vehicle.

Therefore, the device according to the invention makes it possible to obtain records that can be used as evidence at a later date.
