Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic condition photographing device with a diaphragm control function and a traffic condition photographing method, and more particularly, to a violation vehicle ignoring a red traffic light and a violation of traveling over a speed limit. The present invention relates to a traffic condition photographing device with a diaphragm control function and a traffic condition photographing method capable of reliably photographing a vehicle with proper exposure.

[0002]

2. Description of the Related Art Generally, an unmanned vehicle that is traveling on a traffic road such as a public road, even though it has a red traffic light, is monitored unattended, and when the traffic light is ignored, the vehicle is photographed, and later on. Are given to the driver or owner of the vehicle, and prescribed penalties and fines are imposed.

When a violation is detected by not only unattended monitoring that a vehicle enters a crossing despite a red light, but unattended monitoring that the traveling speed exceeds a predetermined speed limit. In addition, shooting is also performed as described above. Then, as a specific example of unmanned monitoring that a vehicle ignores a traffic signal and entering an intersection, and photographing a violating vehicle, there are the following.

That is, as disclosed in Japanese Utility Model Laid-Open No. 60-150531, the main body of the photographing device is installed at a position where the intersection can be overlooked, and the red signal of the vehicle is detected by an appropriate detecting means such as a pressure sensor embedded in the road. When an image of the offending vehicle is taken when the disregard is detected, three types of screens are collectively printed on one photo.

The three types of screens are, firstly, the focal length of the telephoto system so that the license plate on which the registration number for identifying the vehicle is marked and the driver's face can be clearly imaged at a large magnification. The second screen is a screen shot using a shooting lens having a wide-angle focal length over a wide range including a violating vehicle and vehicles around it. is there.

In this way, the second screen is photographed only by the photograph obtained by clearly copying the license plate of the infringing vehicle and the driver's face with a large magnification by the above-mentioned first screen. However, it is sufficient as a so-called evidence photograph, but at the same time, the situation is objectively reconfirmed by taking a wide-angle image of a wide area including vehicles existing around the infringing vehicle.

The third screen displays data such as date and time when the vehicle is violated, for example, "While the traffic light is red at what hour, minute and second of what year, month and day, the vehicle is at the intersection after that. It is a screen displaying data related to a violation time such as “entered” and data such as a number identifying the installation location of the device.

Further, the above-mentioned photographing apparatus is often used in a state of continuous operation for a considerably long time due to its nature, and a part of the members constituting the whole apparatus which requires regular maintenance. It is necessary to make it easy to put on and take off. Because of this, the regular maintenance period is short,
The unit of the shutter mechanism is the actual open Sho 60-150529.
It is desirable to make it attachable / detachable by screwing or the like, as disclosed in the publication.

Now, the photographing position (the position on the road of the vehicle to be photographed) in these various traffic condition photographing devices
Are fixed to a plurality of points set near the position where the vehicle detection means is installed. Therefore, when photographing any one of a plurality of photographing points, an appropriate aperture value is obtained each time before photographing, and the aperture value is controlled to this value. Further, a strobe device is used as auxiliary light when the subject brightness is low, or strobe light is emitted when the subject is backlit.

[0010]

In the conventional setting of the diaphragm of the photographing lens in the traffic condition photographing apparatus, an appropriate diaphragm value is obtained every time photographing is performed prior to film exposure.
In this case, in order to capture a fast-moving subject (violating vehicle) without blurring the image, the shutter speed must be about one thousandth of a second, which inevitably causes the aperture opening to be large, and the desired subject to be captured. There is a risk that the depth of field may not be obtained.

To solve this, some improvement can be expected by using a high-sensitivity film to reduce the diaphragm aperture. However, the exposure control in this case is a shutter-priority control, and therefore the calculated appropriateness is used. It is considered that there is no aperture value, that is, there is no proper aperture value between the maximum aperture based on the optical system of the taking lens and the minimum aperture based on the structure of the aperture.

For this purpose, it is possible to further reduce the diaphragm aperture by using a film with higher sensitivity, but there is a limit due to the deterioration of image quality accompanying the higher sensitivity of the film.

Further, it is conceivable that the photometry is performed for each photographing, and the diaphragm driving ring of the photographing lens is driven to the proper exposure based on the result. In such a case, the photometry is started from the time when the violation is detected. The time required for the calculation, the time required for the photometric calculation, and the time required to drive the diaphragm driving ring to the proper diaphragm position are accumulated.
There is a risk that the timing of the start of shooting will be delayed and the vehicle that has traveled to a position ahead of the predetermined shooting position will be shot, and the intended shooting cannot be performed.

In this case, as a matter of course, the vehicle is traveling during the above-mentioned delay, and therefore, when performing photographing while focusing on an object, complicated distance measurement must be performed in consideration of moving body prediction. However, another problem occurs that the configuration becomes complicated. Further, if a wide range is averaged so as to include a plurality of shooting positions and a so-called fixed aperture is used, the above-mentioned adverse effects due to the delay time can be eliminated, but the appropriate exposure value at each of the plurality of shooting positions can be eliminated. If is significantly different, it may not fit within the latitude of the film.

For this reason, when one of a plurality of planned points is selected and photographed, a traffic violation is detected in each of a plurality of vehicle driving lanes, and the vehicle is located in the lane in which the violation occurred. When photographing the vehicle, only a compromised aperture setting can be made, at the expense of exposure to any one of a plurality of planned spots.

Further, when the strobe is made to emit light at the time of photographing, the above-mentioned problem is improved to some extent.
In order to obtain the aperture value to secure the depth of field for each of multiple shooting positions, it is necessary to obtain the depth of field under the worst conditions, so the amount of light emitted from the strobe device inevitably increases. As a result, the strobe device becomes large in size and the cost of the device becomes expensive.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a plurality of devices against the differences even if the conditions of the place where the traffic condition photographing device is installed are greatly different. Optimum exposure control at each shooting location can be quickly performed, and the aperture setting has been realized so that the violating vehicle can be surely set within the depth of field, and without losing the shooting timing and without image blurring. An object of the present invention is to provide a traffic condition photographing device with a diaphragm control function and a traffic condition photographing method capable of photographing the vehicle.

This is to be stored in the storage unit 37 in advance when the imaging unit 10 is installed, as imaging distance data that specifies a total of eight positions including the four positions.

Simultaneously with this, the input means 36 changes the direction of the photographing optical axis from the place where the photographing section 10 is installed by the direction changing driving section 19 for each of the plurality of traveling lanes 1A to 1D. 2 is driven in such a manner as to be sequentially directed to the photographing positions at predetermined positions, that is, the above eight photographing positions, and the deflection angles from the respective reference directions are used as a plurality of photographing optical axis deflection angle data as the photographing unit. This is for storing in advance in the storage unit 37 when installing 10.

Further, not only the photographing distance data L1 to L8 and the photographing optical axis deflection angle data L1 to L8 are input to the storage unit 37 using the input means 36, but also the magnification change data at each of the above-mentioned eight locations. And aperture data (details of which will be described later) can also be input.

The storage of each data in the storage unit 37 is carried out by observing an actual photographing screen so that the photographing distance data, the photographing optical axis deflection angle data, the magnification changing data, and the aperture value at the above-mentioned eight positions can be stored. By inputting data, shutter speed data, etc. to the storage section 37 via the input means 36, it is possible to perform more practical focusing drive. As a specific example of this, a setting unit 41 that performs a setting operation for the photographing unit 10
Is connected to the control means 35, and the setting means 41 is configured to include the following first to fourth setting means.

That is, the first setting means holds the shutter open as required, and specifically, the shutter of the photographing lens barrel is a valve.
The setting means is to set the aperture of the taking lens barrel to an arbitrary aperture, for example, an aperture or a predetermined value that can secure a minimum depth of field.

The third setting means holds the focusing screen in contact with the film exposure opening. Specifically, the focusing plate made of frosted glass is held in contact with the opening to expose the image. It is possible to visually check it, or to hold it on the light receiving surface of an element such as a CCD for converting an optical image / electrical signal so that it can be checked on a monitor television or the like.

Further, the fourth setting means gives a command for driving the subject distance of the photographing lens to an arbitrary position, and sets two kinds of drive rings for driving the subject distance and the diaphragm aperture to an arbitrary angular position. It can be driven to.
Furthermore, the fifth setting means drives the photographing optical axis to an arbitrary position.

Therefore, while actually confirming the image formed on the exposure aperture surface, while observing the zooming state, the deflection state, the aperture opening state, and the focus state based on the depth of field,
Storage unit 3 with various optimum data as preset data
7 can be stored.

Now, the output end of the storage section 37 in which the data is stored by the input means 36 is connected to the control means 35, and the control means 35 has the first selecting means 38 and the second selecting means 38.
Selection means 39 is connected, and the output of the storage unit 37 is changed to the violating vehicle position specifying means 34 and the first and second selection means 38,
It is supplied to the photographing unit 10 on the basis of the command from 9.

Further, the control means 35, the current diaphragm data and the current distance data detected by the diaphragm detecting means 17, the distance detecting means 18, etc., and the diaphragm data and the photographing distance selected by the second selecting means 39. An arithmetic means 20 for obtaining diaphragm drive amount data, photographing distance data, etc. by comparison with data etc. is connected, and various control signals sent from the output end of the arithmetic means 20 are supplied to the photographing section 10. It is configured.

A diaphragm driving photographing means for driving the diaphragm portion 16 and the focus portion 15 in the above-mentioned photographing lens to photograph in accordance with the diaphragm driving amount data and photographing distance data obtained by the computing means 20. A focusing drive photographing means and the like are configured.

Now, the first selecting means 38 detects when a violation is detected by the violation detecting means 33 with respect to a vehicle traveling in any one of a plurality of traveling lanes 1A to 1D constituting the vehicle passage 1. Whether or not to shoot is determined and the order of shooting is determined and selected.

The second selecting means 39 corresponds to the photographing lane selected by the first selecting means 38 from a plurality of aperture data and photographing distance data stored in the storage section 37 in advance by the inputting means 36. In addition, the aperture data and the shooting distance data corresponding to the violating vehicle position data detected by the violating vehicle position specifying means 34 are selected.

The second selecting means 39 as described above not only selects a plurality of aperture data and photographing distance data, but also
Data such as a plurality of photographing optical axis deflection angle data and variable power data stored in the storage unit 37 via the input unit 36 also correspond to the photographing lane selected by the first selecting unit 38 and are in violation vehicle. It is configured to be selected as data corresponding to the infringing vehicle position data detected by the position specifying means 34.

Further, the above-mentioned input means 36 is constituted so as to allow the input of a range between the maximum aperture value and the minimum aperture value of the aperture of the photographing section 10, for example, and the aperture value which does not actually exist is set. It is configured to prevent an erroneous setting of being stored in the storage unit 37.

Next, the operation of the present embodiment configured as described above will be described with reference to the flowcharts of FIGS. When the power is turned on at step # 0 (hereinafter, "step #" is abbreviated as "#") shown in FIG. 3, power is supplied to each part of the circuit, and the process proceeds to the next step # 1 to perform digital input / output circuit Is reset and other conditions are set. This initial setting includes # 3 shown in FIG.
There are eight kinds of conditions 1 to 8 of 0, and these conditions are executed in parallel or in series. The setting of condition 1 is
This is a setting of an effective lane number, and is used to select which of the four traveling lanes 1A to 1D forming the vehicle traffic path 1 to detect the traffic violation and photograph. Further, it is possible to set in advance the condition in which the violation is detected in the selected traveling lane.

In any of the settings of conditions 2 to 5 described below, the actual photographing screen is observed and actually observed by the first to sixth setting means included in the setting means 41 as described above. By driving the above-mentioned photographing conditions, the conditions at the above-mentioned eight photographing positions are input and set.

The condition 2 is set so that the distance driving ring of the photographing lens barrel in the photographing section 10 is driven manually or by an electric motor to focus on each of a plurality of photographing positions (8 in this embodiment). The shooting distance data of is set in advance in advance. For details, see FIG.
Will be described later.

The setting of condition 3 is optimal for each of a plurality of photographing positions (eight places in this embodiment) having a plurality of photographing magnifications by driving the zoom driving ring of the photographing lens barrel in the photographing unit 10 manually or by an electric motor. This is to preset preset data for changing the magnification so as to obtain the desired value. The setting of Condition 4 is to set preset data for optimizing the aperture value at the time of shooting for each of a plurality of shooting positions (eight places in this embodiment).

When the aperture data is input to the storage unit 37 by using the input means 36, a range between the maximum aperture value and the minimum aperture value of the aperture opening of the aperture unit 16 in the photographing unit 10 is set. The input is allowed, and even if the value of the non-existing aperture opening is input by the input means 36, it is not accepted. As a specific example of the input, the target aperture data is stored in the storage unit 37 by selectively turning on either the up switch or the down switch for increasing the currently set input numerical value.

That is, like from the start to the end of the flowchart shown in FIG. 5, first, at # 41, it is determined whether or not the set aperture value input by the input means 36 is equal to or larger than the minimum aperture value of the aperture section 16. It When YES is determined in # 41, the process proceeds to # 42, and the input operation of only the down switch of the two switches for input setting is permitted, and whether or not the numerical setting is completed is checked in next # 46. If it is determined to be YES, the process ends, and if NO, #
After returning to 41, this # 41 is performed in the same manner as described above, and then the next # 42 and # 46 are sequentially executed, and these operations are repeatedly executed while # 41 is YES.

When # 41 is NO, the next #
After shifting to 43, it is determined whether or not the set aperture value input by the input means 36 is equal to or larger than the maximum aperture value of the aperture unit 16. When YES is determined in # 43, the process proceeds to # 44, where the input operation of only the up switch of the two switches for input setting is allowed, and whether or not the numerical setting is completed is checked in next # 46. If the result of the determination is YES, the process ends, and if NO, the process returns to # 41. After this # 41 is performed in the same manner as described above, the next # 43 and # 44 are sequentially executed. 41 is NO and # 45
Is repeated, it is repeatedly executed.

When # 43 is NO, the next #
In the case of YES, the process proceeds to 45 to allow the input operation of two switches for input setting, that is, both the up switch and the down switch, and in the next # 46, it is determined whether or not the numerical setting is completed. Will be the end and the setting will be completed. Therefore, the aperture data stored in the storage unit 37 by being input by the input unit 36 is set to a value between the aperture value of the minimum aperture and the aperture value of the maximum aperture of the aperture unit 16.

The condition 5 is set by setting the preset data by driving the photographing optical axis to each of a plurality of photographing positions (8 positions in this embodiment) toward the violating vehicle by using the deflection driving unit 19. Is to do. The condition 6 is the film feed setting, which is the setting for the number of frames to be taken before the end of the shooting, and the imprint data when the various data is imprinted on the film at the same time when the violating vehicle is taken. Setting.

The setting of condition 7 is a preset setting of the light emission amount of the strobe unit 50, and specifically, the light amount is changed by changing the capacity of the main condenser of the strobe or stopping the strobe light emission on the way. You can In the case of the present embodiment, there are eight shooting points,
Since there are 4 points on the short distance side and 4 points on the long distance side, 4 points on the short distance side, that is, the vehicle sensor 32 of the second vehicle detection means 32.
It is set to the small light amount mode at the photographing points A to 32D, and is set to the large light amount mode at the four points on the far distance side, that is, at the photographing points of the vehicle sensors 31A to 31D of the first vehicle detection means 31. You can set up.

More strictly, the guide number is set so that proper exposure can be obtained from the set aperture value and shooting distance. The condition 8 is set as a preset shooting cycle, and whether shooting is performed each time a violation is detected in violation detection, or whether a specific time period is set, and whether or not a violation is detected at all times. It is preset whether or not to go and obtain statistical data.

These conditions 1 to 8 can be set by directly inputting the output value of a potentiometer, a counter, or the like, or by inputting means such as an keyboard switch or a touch switch.

When the conditions 1 to 8 are set in # 30 as described above, it is determined whether or not the conditions 1 to 8 have been set by moving to the next # 31. , # 30 is executed again, and in the case of YES, the process proceeds to # 32, and whether or not the condition setting is set to the desired one is repeated to determine whether or not to reproduce, In the case of YES, the process proceeds to # 33 to perform a demo operation, that is, a series of shooting operations are actually performed assuming that a violation occurs in the valid lane number determined by the condition 1 set in # 30. Then, in the next # 34, it is determined whether or not the operation is completed, and if NO, the process returns to # 33, and if YES, the process proceeds to # 40 to close the shutter and start a series of initial operations. The setting is completed.

On the other hand, in the case of NO in # 32, in order to visually confirm the contents of conditions 1 to 8 in # 30, the shutter is opened in the next # 35 and the contents of condition setting are reproduced. . As described above, the focus glass is detachably attached to the exposure opening of the photographing unit 10 by the third setting means of the setting means 41 as described above, and in this state, the shutter is made a valve by the first setting means. It is performed by opening the diaphragm by the second setting means and observing the photographed image on the focus glass.

Then, after the condition setting is driven, the process proceeds to # 37, and whether or not to change the reproduced setting condition is selected in # 37. If YES, the process proceeds to # 38. Then, the setting condition is changed, the changing condition is reproduced, the process proceeds to # 37, and whether to change the setting condition is selected again. If YES, # 38 is executed again.

Then, if # 37 is NO, that is, if it is not necessary to change the setting conditions, the process proceeds to the next # 39 and it is determined that the setting changing operation is completed, and if YES is returned in # 39. In the next step # 40, the valve operation is released and the shutter is closed, the routine for initial setting # 1 shown in FIG. 3 is completed, and the process proceeds to the next step # 2.

This # 2 is for selecting whether or not to shoot the violating vehicle. If the shooting is not to be carried out, the process proceeds to # 3 to select whether or not the condition is changed. If YES in # 2, the condition is confirmed in # 4, and if there is no condition change, YES is selected and the process proceeds to # 5.

In step # 5, the actual operation is performed under the set photographing conditions, and after the operation is completed, the operation is returned to step # 2. on the other hand,
If the answer is NO in # 4, the condition will be changed in # 6.
After the content is confirmed, it is returned to # 2.

If the answer is YES in # 2, the conditions 1 to 8 are set to the standby state immediately before the start of photography so as to suit the varying shooting in # 7. The standby states of the conditions 1 to 8 are listed below. The setting of the condition 1 is the setting of the valid lane number, and the vehicle sensors 31A to 31D, 32A to 32 are set.
One of the Ds corresponding to the preset valid lane number to be detected is set to the detectable state.

The setting of condition 2 is focus setting,
The rotation angle of the focus drive ring of the photographing lens barrel in the photographing unit 10 is set to a predetermined photographing standby position. The shooting standby position may be set, for example, at the closest position to the focus drive ring or at the farthest distance.

More specifically, the current angle position corresponding to the current focus position of the distance drive ring is detected by using the distance detecting means 18, and the angle of the difference from the photographing standby position (target value) is calculated. The direction when driving from the current angular position to the shooting standby position (target value) is detected, and the step driving number corresponding to the driving angle data is obtained.

When a drive pulse signal is supplied to the stepping motor (not shown) by the number of steps thus obtained, the rotation rotates the focus drive ring and the focal length is changed to the photographing standby position (target value). Become.
The setting of Condition 3 is zoom setting, and the rotation angle of the zoom drive ring of the taking lens barrel is set to a predetermined photographing standby position. As the shooting standby position, for example, the zoom drive ring may be set to the widest angle side or the most telephoto side.

More specifically, the current angular position of the zoom drive ring is detected by a variable-magnification drive means (not shown), and the angle of the difference from the photographing standby position (target value) is calculated by the calculation means 20. At the same time, the direction when driving from the current angular position to the shooting standby position (target value) is detected, and the step driving number corresponding to the driving angle data is obtained. Then, by supplying a drive pulse signal to the stepping motor (not shown) by the determined number of steps, the zoom drive ring is rotated and the focal length is changed to the photographing standby position (target value).

The setting of condition 4 is aperture setting, and the aperture of the taking lens barrel is set to a predetermined photographing standby position. The shooting standby position is, for example, the limit aperture value set in advance or the minimum aperture value. Condition 5 is a turning setting, in which the photographing unit 10 having the photographing lens barrel is rotated to a predetermined photographing standby position. The shooting standby position may be the most counterclockwise swung angle or the most swirl clockwise angle.

Incidentally, such driving to the photographing standby position is to drive to an intermediate position by so-called open loop drive control, but the current drive angle of the drive ring is always detected and the stepping motor is driven in a predetermined manner. It is also possible to perform so-called closed-loop drive control in which the drive is performed by the number of steps (a minute amount) and the drive is stopped when the desired angular position is reached. The setting of condition 6 is the setting of the film feeding condition, in which the film stored in the film magazine is fed to be positioned at the opening for exposure and is set to the standby state immediately before photographing.

The setting of condition 7 is the setting of the amount of strobe light emission, and the vehicle sensor 3 forming the first vehicle detecting means 31.
1A to 31D, and the quantity of light set when photographing the violating vehicle and the vehicle sensors 32A to 32D forming the second vehicle detecting means 32. It is necessary to make it different from the amount of light.

For example, when photographing a violating vehicle, first, the violating vehicle located at one of the vehicle sensors 31A to 31D at a long distance is photographed for the first time, and then the violating vehicle is photographed at a short distance. Since the second photographing is performed when the vehicle is located at any of the vehicle sensors 32A to 32D, the strobe light emission amount (GNo) is prepared for the first photographing.
To

The setting of condition 8 is a cycle setting, and which of the vehicles traveling on the plurality of traveling lanes 1A to 1D constituting the vehicle traffic route 1 is traveled when the violation is detected by the violation detecting means 33. I should photograph the vehicle in the lane,
The order of photography is determined or selected by the first selection means 38.

More specifically, when it is detected that any of the vehicles passing through the vehicle sensors 31A to 31D arranged at the first predetermined position is a violating vehicle, the first photographing is performed, Further, the cycle is set such that the second photographing is performed when the vehicle reaches any of the vehicle sensors 32A to 32D arranged at the second predetermined position.

The second selection means 39 is the input means 3
In step 6, from the plurality of shooting angle-of-view data stored in advance in the storage unit 37, the lane corresponding to the lane to be shot is selected by the first selecting unit 38 and is specified by the violating vehicle position specifying unit 34. The second selection means selects shooting angle-of-view data corresponding to the violating vehicle position data.

As described above, when the setting operation from condition 1 to condition 8 to the photographing standby position is executed as # 7 shown in FIG. 3, the process proceeds to the next step # 8 and whether or not the operation is stopped, In other words, when a violation occurs, it is determined whether or not the actual shooting is allowed. If the operation is stopped, the process branches to YES and returns to # 2. On the other hand, in the case of NO, the process proceeds to the next step # 9, and the vehicle sensors 31A to 31D forming the first vehicle detection means 31 detect the vehicle.

Then, in the case of NO in # 9, that is,
When the vehicle is not present on the first vehicle detecting means 31, the process returns to # 8, # 8 is executed again, and # 8 is YES.
This operation is repeated until. If # 8 becomes YES during this repetition, # 2 and # 7 are executed again, then # 9 is executed, and vehicle detection is executed again.

More specifically, the operation of # 9 is performed by the vehicle sensor 3 forming the first vehicle detecting means 31 as shown in FIG.
Whether or not each of the outputs 1A to 31D has occurred is constantly detected by the violation detection means 33, and when passage of the vehicle is detected,
Vehicle passing data including the output generation signal and the address information indicating which of the vehicle sensors 31A to 31D is input to the violation detection means 33.

If YES in # 9, the following #
The process moves to 10 and a violation is judged. That is, traffic light 6
The red signal data input to the violation detection means 33 from is generated at a time point when a predetermined delay time has elapsed after the traffic light 6 started to light in red, and the red signal data described above is generated. It is adapted to be input to the violation detection means 33 together with the vehicle passage data.

The violation detection means 33 determines whether or not the signal is ignored based on the two states of the red signal data and the vehicle passing data. The above-mentioned red signal data is generated after a predetermined delay time has passed since the traffic light 6 turned red. The reason for this is as follows.

In other words, it is inconvenient to add the above-mentioned delay time to one of the factors for judging whether or not to ignore the signal, if the signal is red, if it is simply determined that all of the signals are to be ignored, the actual condition is not met. Is caused. For example, if the vehicle reaches the stop line when the traffic light 6 is illuminated in yellow, it may not be able to stop before or after the stop line and may stop near the center of the intersection. If it is not possible to do so, that is, if there is a risk of a rear-end collision with a following vehicle if stopped by sudden braking, it is inconvenient to violate a vehicle that runs unavoidably at the intersection 5, that is, a so-called legal vehicle. Is.

Therefore, from the moment the traffic light 6 changes from yellow to red, the intersection 5 is crossed from the stop line at a predetermined speed limit.
The delay time is set to allow for a sufficient time (eg, 0.3 seconds) to pass through. Now, N in # 10
In the case of O, that is, when the vehicle passes through any of the vehicle sensors 31A to 31D as the first vehicle detection means 31, the process proceeds to # 15, in which one of the four traveling lanes 1A to 1D. After the statistical traffic information indicating whether or not the vehicle has passed is stored, the process returns to # 8 described above, and the vehicle detection and the statistical data storage are performed again as described above.

Then, when YES is determined in # 10, that is, when the passing vehicle is determined to be ignored by the violation detecting means 33, the process proceeds to # 11 and the first setting condition is set to 1
The first shot is taken. In this detailed operation, as shown in the flowchart of the subroutine of FIG. 6, the vehicle passing data output from the violation detecting means 33 to the violating vehicle position specifying means 34 for the lane in which the violation has occurred is decoded by the violating vehicle position specifying means 34. The violating lane is specified, the control means 35 is activated, and # 50 is executed under the control of the control means 35. This # 50 performs four types of drive, that is, focus drive, zoom drive, diaphragm drive, and direction drive.

First, the data of the lane number (running lane 1C) specified by the violating vehicle position specifying means 34 is input to the control means 35. This violating vehicle position specifying means 34
Is the lane identification data for identifying which of the plurality of traveling lanes the infringing vehicle detected by the infraction detecting means 33 is, and the position of the vehicle in the first or second predetermined position. The violating vehicle position data for specifying whether to perform is generated.

More specifically, the first vehicle detection means 31
And vehicle sensors 3 forming the second vehicle detection means 32 and four installation positions of the vehicle sensors 31A to 31D forming the second vehicle detection means 32.
It is the violating vehicle position data that specifies a total of 8 places including 4 places of 2A to 32D.

In the following operation, it is assumed that the lane in which the violation has occurred is the traveling lane 1C and the position of the vehicle sensor 31C is specified as the violation vehicle position data. The control unit 35 uses the input unit 36 as described above to select from among the distance drive data stored corresponding to the eight positions already stored in the storage unit 37,
Retrieve the data corresponding to the position of the vehicle sensor 31C,
The distance drive ring of the focus unit 15 at the shooting standby position is preset-driven to bring the vehicle above the vehicle sensor 31C into focus.

More specifically, the distance detecting means 18 detects the current angular position of the distance driving ring in the taking lens barrel, and the calculating means 20 uses the angle of the difference from the distance data (target value) as the driving angle data. And the driving direction from the current angular position is detected, and the step number of the stepping motor corresponding to the driving angle data is obtained.

Then, if driving pulse signals are supplied to the stepping motor by the determined number of steps, the photographing distances are stored in correspondence with the eight positions stored in the storage unit 37. The driving data is made to correspond to the shooting distance data L3 corresponding to the position of the vehicle sensor 31C, and the vehicle positioned above this vehicle sensor 31C is in focus.

At the same time as this, the variable magnification drive is performed. This variable-magnification drive uses the vehicle sensor 3 from the variable-magnification data stored corresponding to the eight positions already stored in the storage unit 37 using the input means 36 as described above.
The variable magnification data corresponding to the position of 1C is taken out, and the zoom drive ring of the zoom unit 11 which is at the photographing standby position is preset-driven so that the vehicle located above the vehicle sensor 31C can photograph at a predetermined photographing magnification. To do.

Then, the direction changing drive is performed simultaneously with the focus preset drive and the zoom preset drive. This deflection driving is performed by the vehicle sensor 31C from the deflection data stored corresponding to the eight positions already stored in the storage unit 37 using the input means 36 as described above. The data corresponding to the position is taken out, and the taken-out data is used to direct the position of the camera main body at the photographing standby position, that is, the photographing lens barrel to a predetermined photographing position.

The focus driving, the zoom driving, and the deflection driving are simultaneously performed and the diaphragm driving is performed. This diaphragm drive is performed as follows. That is, as described above, the data corresponding to the position of the vehicle sensor 31C is selected from the aperture data stored respectively corresponding to the eight positions already stored in the storage unit 37 using the input means 36. Is read, and the diaphragm blades of the diaphragm unit 16 at the shooting standby position are driven to the aperture corresponding to the read data.

At this time, the proper aperture value is set to the flash unit 5
The light emission amount of 0 is the data corresponding to the position of the vehicle sensor 31C, that is, the light emission amount in the large light amount mode, from the light emission amount data already stored in the storage unit 37 using the input means 36 as described above. It was obtained based on the standard.

After the focus drive, zoom drive, direction change drive, and aperture drive are executed in # 50, the following # 5 is executed.
The exposure starts at 1 and the strobe light starts,
The offending vehicle traveling on the traveling lane 1C is detected by the vehicle sensor 3
In the state of being positioned at the center of the photographing screen at the position of 1C, it is photographed at a large photographing magnification, and the license plate and the driver's face are clearly photographed.

Next, at # 52, the film is wound and the data is imprinted. The data imprinting content includes unique data that identifies the location where the image capturing unit 10 is installed, a display that identifies that the lane in which the violation has been detected is the traveling lane 1C, and the date and time when the red light comes on. Time data of day, hour, minute, second, and the number of seconds (one hundredth of a second) from when the red light comes on, the vehicle sensor 31C
Indicates that the vehicle has been stepped on by the front wheels of the vehicle, in other words, the signal is ignored and the vehicle has traveled beyond the stop line where the vehicle sensor 31C is installed. It is imprinted on the surrounding area such as.

When the first photographing is completed in this way, the flow shifts to # 53 to perform shutter charging, and it is judged at the next # 54 whether or not it is the second photographing. In the present case, Since it is a single shot, the process branches to NO, # 50
Then, # 51 to # 53 described so far are executed again. And next time, # 54 is Y
The process branches to ES and the process goes to the end of # 55 to complete a series of shooting operations.

Now, when the photographing of the first image is completed under the first setting condition of # 11 shown in FIG. 3, the process proceeds to the next # 12, and the second
The vehicle detection means 32 determines whether the vehicle is detected. If NO, the process returns to # 12 and the second vehicle detection means 32 detects the vehicle and repeats this determination operation until YES. .

Then, at # 12, the second vehicle detection means 32
When the vehicle is detected by, the second image is taken under the second set condition in # 13. Now, storage unit 3
In FIG. 7, four input positions of the vehicle sensors 31A to 31D forming the first vehicle detecting means 31 and the vehicle sensors 32A to forming the second vehicle detecting means 32 have already been installed using the input means 36. The focus drive data, the zoom drive data, the deflection drive data, and the like corresponding to each of a total of eight installation positions of four installation positions of 32D are stored.

Here, the above-mentioned first setting condition means the vehicle sensors 31A to 31D forming the first vehicle detecting means 31.
The focus drive data, the zoom drive data, the deflection drive data, and the aperture drive data corresponding to the four installation positions are selectively set.

The second set condition is the focus drive data, the zoom drive data and the deflection drive corresponding to the four installation positions of the vehicle sensors 32A to 32D forming the second vehicle detection means 32. The data and the diaphragm drive data are selectively set.

Then, the photographing under the second setting condition is as shown in FIG.
Similar to the flowchart shown in FIG. 1, first, the focus drive ring of the focus unit 15 installed at the position driven by the first photographing is preset-driven to determine the position of the vehicle sensor 32C installed in the traveling lane 1C. Put the vehicle in focus on the offending vehicle.

Simultaneously with this, zoom drive is performed. This zoom drive is performed by using the input means 36 as described above, and the data corresponding to the position of the vehicle sensor 32C is selected from the photographing distance data already stored in the storage unit 37 corresponding to the eight positions. Of the violating vehicle located above the vehicle sensor 32C by preset-driving the zoom drive ring of the zoom unit 11 located at the position driven by the first image capturing, including other vehicles existing around the violating vehicle. A wide range can be photographed at a predetermined photographing magnification.

The focus preset drive, the zoom preset drive, and the diaphragm drive are performed at the same time. In this diaphragm drive, the diaphragm drive ring which is in the position driven by the first photographing is set to the diaphragm data corresponding to the position of the vehicle sensor 32C from the diaphragm data already stored in the storage unit 37. More specifically, the amount of light emitted from the flash unit 50 is calculated based on the amount of light emitted in the small light amount mode, and as described above, the vehicle is selected from the amount of light emission data already stored in the storage unit 37 using the input means 36. The diaphragm data corresponding to the position of the sensor 32C is taken out, and the diaphragm is driven corresponding to this data.

As described above, the aperture preset drive is performed simultaneously with the focus preset drive, the deflection preset drive, and the zoom preset drive. Then, in order to satisfy the respective conditions of the focus drive data, the zoom drive data, the deflection drive data, and the aperture data, which are stored in the storage unit 37 in advance by using the input means 36, corresponding to the position of the vehicle sensor 32C. When the vehicle is driven at 50, immediately after that, exposure is started at # 51 and strobe light emission is started, and a violating vehicle traveling on the traveling lane 1C forming the vehicle passage 1 reaches the position of the vehicle sensor 32C. With the violating vehicle facing the center of the shooting screen, a wide range including other vehicles located around the violating vehicle is taken with proper exposure.

Next, as in the case of the first photographing, # 5
In 2 the film is wound and the data is imprinted. When the second shooting is completed in this way, the process proceeds to # 53 and the shutter is charged, and the next # 54 is the second shooting. Whether or not it is determined. In this case, since the second shooting has been completed, the process branches to YES, and a series of shooting processing ends in # 55.

In this way, when the first and second photographings are performed as shown in FIG. 6 showing the details of # 11 to # 13 (see FIG. 3), the process of # 14 shown in FIG. 3 is performed. As described above, the statistical data such as the violation date and time, the violation state, and the violation data regarding the first and second shootings are stored, returned to the next step # 7, and waited until the violation vehicle is detected again. is there.

Therefore, the traveling vehicle is the first vehicle detection means 3
Immediately after the violation is detected at position 1, the vehicle is clearly photographed with a large photographing magnification and the vehicle license plate positioned in the center of the screen. Further, in this photographing, the stroboscopic light is emitted from the stroboscopic light emitting section 50, so the face of the driver in the vehicle, which is usually underexposed, is irradiated with the stroboscopic light, and the face of the driver is also exposed. It will be taken clearly.

Further, in the second photographing, not only the violating vehicle but also a wide range including the surrounding situation is photographed, so that the state of the violating vehicle can be comprehensively judged.

In the present embodiment, more specifically, a plurality of preset photographing points (the first vehicle detection means 31 4).
The optimum focus data, zoom data, turning data, and aperture data at each of the four points and the four points of the second vehicle detection means 32) are stored in the storage unit 37 as preset data when the traffic condition photographing device is installed. Pre-stored, first
Each time a vehicle is detected by the vehicle detection means 31 of No. 1, it is determined whether or not the passing vehicle is in violation of the signal disregard based on the state of the traffic light 6, and the violation occurs in the traveling lanes 1A to 1D. Which one of the four vehicle sensors 31A to 31D is associated with the corresponding position of the four vehicle sensors 31A to 31D, the focus drive data, the zoom drive data, and the deflection drive data of the storage unit 37 are identified. take out,
Since focus drive, zoom drive, deflection drive, and aperture drive are performed according to the extracted data, it is possible to immediately obtain the optimum focal length, subject distance, deflection direction, and proper aperture value at the shooting position.

The installation of the traffic condition photographing device can be optimized according to the number of traveling lanes at the installation place, the width of the lane, the position of the traffic light, etc., so that it has great versatility. .

Further, when the focus drive data, the zoom drive data, the deflection drive data, and the aperture data are stored in the storage unit 37 as preset data when the traffic condition photographing device is installed, the focus plate can be detachably attached to the exposure opening. Since the so-called initial setting is performed while visually checking the actual subject image with the shutter fully open, the traffic condition is the location where the image capturing device is installed, specifically, the number and width of driving lanes. It is possible to set an optimal shooting screen that comprehensively considers the surrounding conditions.

Next, a second embodiment of the present invention will be described. Before describing the second embodiment in detail with reference to FIGS. 7 to 10, the purpose of this embodiment will be briefly described. In the first embodiment described above, the light from the strobe unit 50 is used as a main light source for shooting, whereas in the second embodiment, shooting is performed using both natural light and light from the strobe unit 50. Is.

The structure of the second embodiment differs from the structure of the first embodiment described above in focusing, zooming, and changing in the standby state in the diaphragm drive shooting mode by the diaphragm driving shooting means. The intermediate position return commanding means 93 for driving the respective operations of the aperture and the diaphragm to an intermediate angle in a change angle range based on a plurality of data stored in advance in the storage section by the input means is added.

Further, a photometric unit (not shown) for photometrically measuring the brightness of the subject to be photographed is provided in the photographing unit 10, and the subject luminance data obtained by photometry of the subject at the time of photographing by the photometry unit, the film sensitivity data, and When the calculation aperture of the diaphragm obtained by calculating the shutter speed data and the aperture is smaller than the limit aperture set in advance to obtain a predetermined depth of field, the aperture is driven to the calculation aperture, and the calculation aperture is When the aperture is larger than the limit aperture, aperture limiting means 94 for giving a control command for driving the aperture to the limit aperture is added.

The purpose of adding the diaphragm limiting means 94 is as follows. Since the photographing purpose of the device according to the present invention is to obtain the evidence photograph of traffic violation, it is required to clearly photograph the license plate of the violating vehicle and the driver's face photograph of the vehicle, and the subject is a moving vehicle. Therefore, the shutter speed requires about one thousandth of a second, and the aperture value is inevitably set to the open side. But,
If the aperture is set to the open side, it means that the depth of field becomes shallow and it is not possible to clearly capture the image.

Therefore, at the time of photographing, a shutter speed of about one thousandth of a second that does not cause blurring is ensured, and the aperture value of the proper exposure determined based on the shutter time is the minimum depth of field. When it is not possible to secure the aperture, do not use the aperture value for proper exposure, and be prepared to take a certain amount of underexposure, and shoot with the aperture value stopped down to the minimum depth of field. The purpose is to ensure clear shooting.

Next, the second embodiment will be described in detail with reference to FIGS. The overall configuration of the traffic condition photographing device is
The block diagram shown in FIG.
In the embodiment shown in FIG. 1, the intermediate position return command means 93 is provided.
Is added to the intermediate position return commanding means 93.
The output end of is connected to the control means 35.

That is, the intermediate position return command means 93 is
In the standby state in the diaphragm drive photographing mode by the diaphragm drive photographing means composed of the photographing section 10 and the control section 30, the diaphragm of the photographing lens is set to a plurality of diaphragms stored in advance in the storage section 37 by the input means 36. It is designed to be driven to an intermediate angular position in the change range based on the data.

Further, similarly to the case where the diaphragm drive is performed in the standby state in the photographing mode, the respective drive angular positions of the direction changing drive, the magnification changing drive, and the focusing drive are set to the intermediate angle position of the drive angle range. The drive is controlled. Further, the diaphragm limiting means 94 is added to the configuration of FIG. 1 in the above-described first embodiment, and the output end of the diaphragm limiting means 94 is connected to the control means 35.

That is, the aperture limiting means 94 is used for subject brightness data obtained by photometry of a subject to be photographed at the photometry section at the time of photography, sensitivity data of a film mounted on the photography section 10, and film exposure of the photography section 10. When the calculation aperture of the diaphragm obtained by calculating the shutter speed data of the unit 14 is smaller than the preset limit aperture to obtain a predetermined depth of field, the diaphragm is driven to the calculation aperture, and When the calculated aperture is larger than the limit aperture, the diaphragm is driven to the limit aperture.

Next, the operation of the second embodiment will be described more specifically with reference to FIGS. The flowchart shown in FIG. 8 shows the operation of the second embodiment.
Since 60 to # 73 are the same as or similar to # 0 to # 13 in FIG. 3 showing the operation of the first embodiment described above,
In order to avoid duplication, description of similar parts will be omitted, and only different parts will be described.

When the power is turned on at # 60, the power is supplied to each part of the circuit, the process goes to the next # 61, the digital input / output circuit is reset, and other conditions are set. As shown in detail in FIG. 9, this initial setting is to set an effective lane number similarly to the setting of the condition 1 in the above-described first embodiment, and the four running lanes forming the vehicle passage 1 are set. One of 1A to 1D is selected to detect a traffic violation and photograph. Further, it is possible to specify the condition in which the violation is detected in the selected traveling lane.

Next, shifting to # 80 in FIG. 9, the setting of the five conditions from condition A to condition E is executed in parallel or in series. In any of the settings of conditions A to E described below, the conditions at the above-described eight shooting positions are input and set by observing an actual shooting screen. That is, in response to a command from the setting unit 41, the focus glass is detachably attached to the exposure opening of the image capturing unit 10, and in this state, the shutter is used as a valve to open the diaphragm to observe various captured images on the focus glass. Is set.

The condition A is the same as the condition 2 in the above embodiment, the condition B is the same as the condition 3 in the above embodiment, the condition C is the same as the condition 4 in the above embodiment, and the condition D is the same. Is the same as the condition 5 in the above embodiment. The condition E is the same as the condition 6 (film feed setting), the condition 7 (preset setting of the light emission amount of the strobe light emitting section 50), and the condition 8 (preset setting of the photographing cycle) in the above-described embodiment.

The settings of these conditions A to E can be input by a keyboard switch, a digital switch, a touch type switch, a potentiometer, a rotary encoder, or the like.

When the conditions A to E are set in # 80 as described above, the process proceeds to the next # 81 and these conditions A to E are set.
The four conditions D are executed in parallel or in series and drive to an intermediate value.

The driving to the intermediate value under the conditions A to D will be successively described for each of the conditions A to D. The driving to the intermediate value in the condition A is to set the rotation angle of the focus driving ring of the taking lens barrel to the intermediate position. That is, of the plurality of shooting distance data preset corresponding to the effective lane number, the rotation angle position of the focus drive ring required to focus the closest one and the farthest one. The distance is set to an angle intermediate to the rotational angle position of the drive ring.

The driving to the intermediate value in the condition B is to set the rotation angle of the zoom driving ring of the taking lens barrel to the intermediate position. That is, of the plurality of zoom data preset corresponding to the effective lane number, the rotation angle position of the zoom drive ring that is closest to the wide angle and the rotation angle position of the zoom drive ring that is closest to the telephoto Set it at an intermediate angle.

The driving to the intermediate value in the condition C is performed by setting the aperture of the taking lens barrel to the rotation angle position of the aperture drive ring corresponding to the minimum aperture value of the preset aperture values and the preset aperture value. The set aperture value is set to an intermediate angular position of the change angle between the rotational angle position of the diaphragm driving ring and the maximum aperture value of the plurality of set aperture values. The driving to the intermediate value in the condition D is performed between the one having the maximum turning angle and the one having the minimum turning angle among the plurality of photographing field angle data preset corresponding to the already-specified effective lane number. It is driven so that it becomes the angular position of.

In this embodiment, since the four preset effective lanes are the traveling lanes 1A to 1D,
Since the photographic optical axis deflection angle D1 is the minimum deflection angle and the photographic optical axis deflection angle D8 is the maximum deflection angle, the photographic optical axis of the photographic lens barrel is set so as to be at this intermediate angle position. It is driven to change direction.

The driving to such an intermediate value is performed as the steps of the flow chart whose details are shown in FIG. Although this step is expressed so that it can be applied to any of the above-mentioned conditions A to D, the case of the diaphragm operation of condition C will be specifically described, and other conditions A,
Detailed description of the driving operation to the intermediate value in B and D is omitted.

First, the current value is detected at # 82.
This detection is performed by obtaining the output obtained by detecting the current angular position of the diaphragm drive ring by the diaphragm detection means 17 of the photographing unit 10.
Next, in # 83, the target value is set. For this target value, the preset valid lanes are the traveling lanes 1A to 1A.
Since there are four apertures D, the drive angular position corresponds to the intermediate aperture of the minimum aperture value and the maximum aperture value of the diaphragm data corresponding to these four apertures. Further, this drive angular position is determined based on a command from the diaphragm limiting means 94.

That is, the aperture limiting means 94 is used for subject brightness data obtained by photometry of the object to be photographed by the photometry unit at the time of photography, sensitivity data of the film mounted on the photography unit 10, and film exposure unit of the photography unit 10. The calculation aperture of the aperture obtained by calculating the shutter speed data of 14 has
The aperture is driven to a calculation aperture when the aperture is smaller than a preset limit aperture to obtain a predetermined depth of field, and the aperture is driven to the limit aperture when the aperture is larger than the limit aperture.

If it is determined by the photometry section that the amount of light is insufficient, the strobe section 50 is caused to emit light. Then, in the next step # 84, difference data between the current value data obtained in step # 82 and the target value data obtained in step # 83 is calculated using the computing means 20, and the step rotation drive corresponding thereto is performed. The target step number C of is calculated. At the same time, the polarity of the difference data, that is, the drive direction is specified, and the process proceeds to the next step # 85.

At # 85, the rotation direction of the stepping motor is set so as to correspond to the polarity of the difference data obtained at # 84, and the process proceeds to the next # 86 to drive the step rotation in the direction set at # 85. Then, the process proceeds to # 87. At # 87, the actual driving step number N of the stepping motor actually step-driven is detected, and at the next # 88, C
It is determined whether or not ≧ K · N.

Incidentally, K is a coefficient existing between the rotation of the stepping motor and the change of the photographing distance. This # 8
When C ≧ K · N is NO in step 8, the stepping motor is continuously step-driven, and again in step # 88, C ≧ K · N.
N determination is made. This state continues while # 88 is NO, and when YES, the routine proceeds to the next # 89, where the stepping motor drive is stopped and the brake is applied at the same time. The operation of driving to the target angular position (shooting standby position) is completed.

Incidentally, such driving to the photographing standby position is to drive to an intermediate position by so-called closed loop drive control, but the present rotation angle of the diaphragm driving ring is detected and the stepping motor is set to a predetermined value. It is also possible to perform so-called open-loop drive control in which the drive is stopped after being driven by the number of drive steps.

When the initialization in # 61 of FIG. 8 is performed as described above, the following # 62 to # 73 are executed in the same manner as # 2 to # 13 of the first embodiment, The process proceeds to # 74 following # 73 and the drive to the intermediate position is performed similarly to # 81.

Further, in this embodiment, the driving position for photographing the violating vehicle driven by the first photographing under the first setting condition shown in # 71 is maintained as it is, and the second setting is performed from this state. Although it is designed to be driven to the target position according to the second shot under the conditions, # 7 indicated by the broken line in FIG.
As in step 7, step # 72 may be additionally provided with step # 77 for performing an intermediate position driving step similar to step # 74.

When the aperture data is input to the storage unit 37 by using the input means 36, a range between the maximum aperture value and the minimum aperture value of the aperture opening of the aperture unit 16 in the photographing unit 10 is set. The input is allowed, and even if the value of the non-existing aperture opening is input by the input means 36, it is not accepted. This is similar to the first embodiment described above. Now, in the present embodiment, the plurality of diaphragm data stored in the storage unit 37 are not unconditionally driven as they are, but the following restrictions are imposed.

This is the setting of the light emission amount of the strobe unit 50 as described above, that is, the setting of whether the light amount is the large light amount mode or the small light amount mode, the film sensitivity data, and the shutter second data. When the calculated aperture of the proper aperture (data stored in the storage unit 37 using the input means 36) obtained by the above is smaller than the limit aperture preset to obtain a predetermined depth of field, the aperture is set to the aperture. Drive,
When the calculated aperture is larger than the limit aperture, the aperture limiting means 94 sends a control signal to the control means 35 to drive the aperture to the limit aperture.

Further, since these limit apertures are aperture aperture values required to secure the necessary minimum depth of field, they naturally vary depending on the subject distance. Therefore, a plurality of photographing positions, that is, 8 of the vehicle sensors 31A to 31D and the vehicle sensors 32A to 32D are used.
8 corresponding to the subject distance data at each of the locations
The limit opening data of the location is stored in the storage unit 3 via the input means 36.
Stored in 7.

The limit aperture naturally changes according to the focal length of the taking lens.
For this purpose, a plurality of photographing positions, that is, the vehicle sensor 31A
.About.31D and vehicle sensors 32A to 32D, the limiting aperture data at eight locations obtained by considering both the focal lengths (magnification data) at each of the eight locations and the subject distance data described above are input means 36. It is stored in the storage unit 37 via the.

Therefore, the aperture value of the calculated aperture (aperture value for proper exposure) at each of the above eight locations based on the command from the aperture limiter 94 becomes such that the minimum depth of field cannot be ensured. Sometimes, without using the aperture value of the calculation aperture,
Being prepared for a certain amount of underexposure, clear shooting is ensured by shooting with an aperture value that allows the minimum depth of field to be secured.

Therefore, in this embodiment, for each of the focus drive of condition A, the zoom drive of condition B, the diaphragm drive of condition C, and the deflection drive of condition D, the intermediate position is set before the drive to the target value. Since it is driven to, it is possible to reduce the amount of drive prior to shooting, and to shorten the preparation time prior to shooting. Along with this, the time lag between the shooting start command time (the time when the violating vehicle reaches the first vehicle detection means 31 or the second vehicle detection means 32) and the time when the shooting is actually started is extremely reduced. You can do it.

Further, in order to drive the diaphragm of the photographing lens to photograph a high-speed moving subject (violating vehicle) without image blur, a high-speed shutter time of about one thousandth of a second is ensured, and a desired depth of field is obtained. Since the control command is issued by the aperture limiting means 94 so that the value of the above can be obtained, it is possible to obtain a clear evidence photograph in focus on both the license plate of the infringing vehicle and the driver's face.

Next, a third embodiment of the present invention will be described with reference to FIGS. In the above-described first and second embodiments, when the first vehicle detection means 31 detects a violating vehicle, the first image capturing is started, and the second vehicle detection means 32 detects that the violating vehicle has arrived. 2 when detected
Although the timing is set so as to start the photographing of the first sheet, in the third embodiment, the timing is set so that when the vehicle detection means 91 detects a violating vehicle, the first image is photographed. 2 when a predetermined time has passed from the time
It is designed so that the first picture is taken.

The overall structure of this traffic condition photographing device is shown in FIG.
As shown in the block diagram of FIG. 1, its main part is composed of a photographing unit 10, a flash unit 50, and a control unit 100. The photographing unit 10 and the strobe unit 50 are the same as those in the first embodiment described above.

Further, in this embodiment, as shown in FIG. 12, there are a vehicle passage 1 formed of four traveling lanes 1A, 1B, 1C and 1D and a vehicle passage 2 formed of four lanes. A vehicle traveling on a vehicle passage 1 at an intersection 5 at which a four-lane road formed by four lanes and a four-lane road on each side intersect in a cross shape. When the vehicle ignores the signal, the vehicle is photographed.

As shown in FIG. 12, a traffic signal 6 is installed at a predetermined height position of the vehicle passage 1 in front of the intersection 5, and is installed immediately before the intersection 5 in each of the four traveling lanes 1A to 1D. Vehicle detection means 91 formed of four vehicle sensors 91A, 91B, 91C and 91D is provided on the road surface near a stop line (not shown) corresponding to each of the traveling lanes 1A to 1D.

The vehicle detecting means 91 detects that the vehicles traveling on the traveling lanes 1A to 1D in the vehicle passage 1 have reached a predetermined position set in each traveling lane, that is, near the stop line. To do. These vehicle sensors 91A to 91D are pressure sensors that detect arrival of the vehicle by being stepped on by the tires of the traveling vehicle.

The output terminals of the vehicle sensors 91A to 91D forming the vehicle detection means 91 are connected to the input terminals of the violation detection means 33 at the next stage. Vehicle sensors 91A-9
Vehicle detection by 1D is repeatedly performed at a predetermined cycle. A code for identifying which vehicle sensor the output is from is added to each of these outputs.

The violation detecting means 33 is the vehicle detecting means 9 described above.
When the passage of the vehicle is detected by 1, it is determined whether or not the vehicle is in violation of traffic, and the vehicle detection data from any of the vehicle sensors 91A to 91D is supplied as described above. It is like this.

Then, this violating vehicle position specifying means 34 is used.
Generates lane identification data that identifies which of a plurality of traveling lanes the infringing vehicle is traveling in, and specifically identifies four installation positions of the vehicle sensors 91A to 91D. It is the offending vehicle position data.

Further, the violation detecting means 33 is connected to the starting input terminal and the output terminal of the timer circuit 92 whose set time is t seconds. The reason for providing this timer circuit 92 is that when the vehicle that has reached the vehicle detection means 91 is a violating vehicle, the first shooting is performed, and then the second shooting is performed. This is because the set time is decided.

Since the second shooting is performed to reconfirm the state of the infringing vehicle, the shooting of a wide range including not only the state of the infringing vehicle but also other vehicles located around it is also taken. Is done. The set time t seconds is determined as follows.

That is, when the vehicle passing through the vehicle detecting means 91 is in violation, the first photographing is performed and the second photographing is performed after a predetermined time, so that the second photographing position is set to the vehicle traffic route. Driving lanes 1A to 1D that compose 1
There is a problem of which position of the target should be targeted.

This is the second photographing position in the above-mentioned embodiment, that is, the second vehicle detecting means 32 (see FIG. 2).
It suffices to set the time required to reach the position, but the traveling distance is not specified because the speed of the passing vehicle is not specified. For example, during a time t seconds, a mileage L1 of a vehicle traveling below a prescribed speed, a mileage L2 of a vehicle traveling significantly above the prescribed speed, and a mileage L3 of a vehicle traveling at a prescribed speed. There is a question of which one to adopt.

The situation of the vehicle traveling on this road cannot be determined without statistically examining it, but the second photographing is intended to photograph the surrounding situation including the violating vehicle. However, even if the photographing position is changed to some extent, it does not cause any other problem. Therefore, in the third embodiment, the distance L3 reached by the vehicle traveling at the specified speed for t seconds from the vehicle detection means 91 is the second time. It was adopted as the shooting position.

The violating vehicle position specifying means 34 determines whether the violating vehicle detected by the violating detecting means 33 is one of the plurality of traveling lanes and the lane specifying data for identifying the vehicle. The violating vehicle position data for specifying whether the vehicle is located at the first predetermined position or the second planned position is generated.

More specifically, it is orthogonal to the four positions of the first photographing position, which is the installation position of the vehicle sensors 91A to 91D forming the vehicle detecting means 91, and the direction of the distance L3, which is the second photographing position. It is the violating vehicle position data that specifies a total of 8 places including the respective 4 places of the traveling lanes 1A to 1D.

The input means 36 is also equipped with vehicle sensors 91A to 91D which are the first and second photographing positions of the plurality of traveling lanes 1A to 1D, that is, the first photographing positions.
The focus setting, zoom setting, aperture setting, and turning corresponding to each of the four specifying positions, namely the four setting positions and the second setting position (planned setting position) The setting is performed and the data is stored in the storage unit 37, which is basically the same as the first embodiment.

Further, these data are set by detachably attaching the focus glass to the exposure opening, and in this state, various settings are made while visually observing the photographed image on the focus glass by using the shutter as a valve and visually confirming. After that, it is finally stored in the storage unit 37 as setting data.

The first selecting means 38 determines which of the traveling lanes 1A to 1D constituting the vehicle passage 1 is traveling by one of the traveling lanes when the violation detecting means 33 detects a violation. It decides whether to shoot and the order of shooting. The second selection means 39 is the input means 3
8. Corresponding to the violating vehicle position data detected by the violating vehicle position specifying means 34, corresponding to the photographing lane selected by the first selecting means 38 from the plurality of data stored in advance in the storage unit 37 in 8. This is for selecting the selected data.

Further, the diaphragm data selected by the second selecting means 39 constitutes the diaphragm driving photographing means for photographing by driving the diaphragm in the photographing section 10 to the optimum diaphragm value for the violating vehicle.

Next, the operation of the third embodiment will be described with reference to FIG. The flowchart shown in FIG. 13 shows the operation of the third embodiment. From # 90 to # 101, # 0 to # 13 in FIG. 4 showing the operation of the above-described first embodiment.
Since it is the same as or similar to, the description of the same parts will be omitted to avoid duplication, and only different parts will be described.

When the power is turned on in # 90, the power is supplied to each part of the circuit, the process proceeds to the next # 91, the digital input / output circuit is reset, and other conditions are set. This initial setting is the same as that in the above-described first embodiment, and is the same as that in the above-mentioned first embodiment up to the following # 101.

In # 102 executed after # 101, the timer circuit 92 is started at the time when the first photographing is started, and the timer elapsed time reaches the time t in the next # 103. It is determined whether or not, and if NO, then YE
# 103 is repeatedly executed until S is reached, and when YES is determined, the process proceeds to the next # 104, and the second shooting is performed under the second setting condition in the same manner as in the above-described first embodiment.

Now, in the storage section 37, the four input positions of the vehicle sensors 91A to 91D forming the vehicle detection means 91 are set by using the input means 36 when the image pickup section 10 is installed, and the second image pickup position. The focus drive data, the zoom drive data, and the deflection drive data corresponding to each of the eight locations in total are stored.

Here, the above-mentioned first set conditions are the focus drive data, the zoom drive data, and the deflection drive corresponding to the four installation positions of the vehicle sensors 91A to 91D forming the vehicle detection means 91. It is a condition regarding data. The second setting condition is a condition relating to focus drive data, zoom drive data, and deflection drive data corresponding to four positions of the second photographing position.

In the photographing under the second setting condition, the focus drive ring of the focus unit 15 set to the position driven by the first photographing is preset driven in the same manner as described above, and the predetermined traveling lane 1C is obtained. The violating vehicle traveling at the shooting position (schedule shooting position) scheduled to arrive after the time (t) is brought into focus.

Simultaneously with this, the variable-magnification drive is performed. This variable power drive is performed by using the input means 36 as described above, from the variable power data stored in the storage unit 37 and corresponding to the eight positions, respectively, from the traveling lane 1C. Take out the data corresponding to the shooting position scheduled for
The violating vehicle located near the planned shooting position by preset-driving the zoom drive ring of the zoom unit 11 set to the position driven by the first shooting includes other vehicles around it. Make it possible to shoot a wide area at a predetermined shooting magnification.

Simultaneously with such focus preset drive, zoom preset drive, and variable power drive, diaphragm drive is performed. This diaphragm drive drives the diaphragm drive ring, which is set at the position driven by the first shooting, so as to change the diaphragm value required to give proper exposure according to the diaphragm data at the planned shooting position. Is. Then, the direction changing drive is performed simultaneously with the focus preset drive, the zoom preset drive, and the aperture drive. This deflection driving is performed as follows.

As described above, using the input means 36, from among the turning drive data stored respectively corresponding to the eight positions already stored in the storage section 37, the first data on the traveling lane 1C is selected. The photographing distance data corresponding to the photographing position (scheduled position) of No. 2 is taken out, and the position of the zoom drive ring, which is the position driven by the first photographing, that is, the taking distance is taken as the second taking distance. Is optimal for the shooting position of.

Then, as in # 101 and # 104, the first
When the second shooting and the second shooting are performed, the statistical data such as the violation date and time, the violation status, and the violation data regarding the first and second shootings are stored in # 105 and returned to # 97. , It is put in a standby state until a violating vehicle is detected again.

Therefore, immediately after the traveling vehicle is detected as a violation at the position of the vehicle detecting means 91, the vehicle license plate of the vehicle positioned at the center of the screen is clearly photographed with a large photographing magnification. Further, since this flash photography is performed by the flash unit 50 emitting light, normally, the driver's face in the vehicle in the under-exposed state is irradiated with the strobe light, and the driver's face is also exposed. It will be taken clearly.

Further, in the second shooting, not only the infringing vehicle but also the surrounding area is photographed, so that the state of the infringing vehicle can be comprehensively judged.

In this embodiment, optimum focus drive data and zoom drive are set at each of a plurality of preset photographing points (4 points of the vehicle detecting means 91 and 4 points of the second photographing position). The data and the turning drive data are stored in the storage unit 37 as preset data when the traffic condition photographing device is installed, and each time the vehicle detection unit 91 detects a vehicle, whether the passing vehicle is a signal ignoring violation or not is determined. The determination is made based on the state of the traffic light 6, and it is specified which one of the traveling lanes 1A to 1D is driving the violating vehicle.
The focus drive data, the zoom drive data, and the deflection drive data in the storage unit 37 are read out in correspondence with the corresponding positions of one of the vehicle sensors 91A to 91D, and the focus drive and the zoom drive are respectively executed according to the read-out data. Since the deflection driving is performed, it is possible to obtain the optimum focal length, subject distance, and deflection direction at the photographing position.

Further, the vehicles that have reached the vicinity of the second photographing position after a lapse of a predetermined time from the completion of the first photographing are stored in the storage unit 37 corresponding to each of the four photographing positions. Focus drive data, zoom drive data,

Hereinafter, a fourth embodiment of the present invention will be described with reference to FIGS.
This will be described using 5. In the fourth embodiment, in addition to the structure of the third embodiment, a plurality of aperture openings are stored in advance in the storage unit by the input unit in the standby state in the aperture drive photographing mode by the aperture drive photographing unit. The intermediate position return commanding means 93 for driving to an intermediate angle in the change angle range based on the diaphragm data is added.

Further, the aperture limiting means 9 in the first embodiment.
4 and the same parts as the photometric unit are added. Further, the subject brightness data obtained by the photometry unit and the photographing unit 10
The calculation aperture obtained by calculating the sensitivity data of the film attached to the camera and the shutter speed data of the photographing unit 10 is
A diaphragm limiting unit 94 that drives the diaphragm to a calculation aperture when the size is smaller than a preset limit aperture to obtain a predetermined depth of field, and drives the diaphragm to the limit aperture when the calculation aperture is larger than the limit aperture. It is provided similarly to the second embodiment.

Further, the light emission amount switching function for changing the light emission amount of the strobe section 50 for illuminating the subject to be photographed and the calculation aperture obtained by the calculation by the diaphragm limiting means 94 are for obtaining a predetermined depth of field. When the aperture is larger than a preset limit aperture, the aperture is held at the limit aperture, and the amount of light emitted from the strobe unit 50 is controlled to a value determined by the subject distance data obtained by the distance detection unit 18 and the aperture limit aperture. Control means 35 having a light emission amount switching function
Is configured.

The overall structure of this traffic condition photographing apparatus is as shown in the block diagram of FIG. 14, and an intermediate position return command means 93 is added to the structure of FIG. 11 in the above-mentioned third embodiment. The output end of the intermediate position return command means 93 is connected to the control circuit 35.

That is, the intermediate position return command means 93 is
In the standby state in the diaphragm driving photographing mode by the diaphragm driving photographing means, the diaphragm aperture is driven to an intermediate angular position of the change angle range based on a plurality of diaphragm data stored in advance in the storage section 37 by the input means 36. It has become. Further, also in focus drive, zoom drive, and direction change drive, similarly to the drive to the intermediate value of the diaphragm, the drive control is performed to the intermediate angle position of the drive angle range in the standby state in the shooting mode. .

Next, the operation of the fourth embodiment will be described with reference to FIG. The flow chart shown in FIG. 15 shows the operation of the fourth embodiment, and from # 200 to # 211 the # 60 to # in FIG. 8 showing the operation of the above-mentioned second embodiment.
Since it is the same as 71, the description thereof is omitted to avoid duplication, and only different parts will be described.

When the power is turned on in # 200, power is supplied to each part of the circuit, the process proceeds to the next # 201, the digital input / output circuit is reset, and other conditions are set. This initial setting is the same as that in the above-mentioned second embodiment, and is the same as that in the above-mentioned second embodiment up to the following # 211.

# 212 to # 214 executed after # 211 are # 102 to # 10 in the third embodiment.
4 (see FIG. 13). Next # 215 is # 2
At the time point when the second shooting is completed in 14, the drive angle positions of the variable power drive, the focus drive, the diaphragm drive, and the direction drive are controlled to the intermediate angular position of the drive angle range. This is the same as # 74 (see FIG. 8) in the second embodiment.

At the intermediate drive position of the aperture drive, since the four preset effective lanes are the traveling lanes 1A to 1D, the intermediate aperture of the minimum aperture value and the maximum aperture value of the aperture data corresponding to these four lanes. That is, the drive angular position corresponds to. Further, the aperture drive angular position at the time of shooting is determined based on a command from the aperture limiter 94.

That is, the aperture limiting means 94 is used for subject brightness data obtained by photometry of a subject to be photographed by the photometry unit at the time of photography, sensitivity data of the film mounted on the photography unit 10, and film exposure unit of the photography unit 10. When the calculation aperture of the diaphragm obtained by calculating the shutter speed data of 14 shutters is smaller than the preset limit aperture to obtain a predetermined depth of field, the diaphragm is driven to the calculation aperture, However, when it is larger than the limit aperture, the diaphragm is driven to the limit aperture. If it is determined that the amount of light is insufficient by the photometry in the photometry unit, the strobe unit 50 is caused to emit light.

Further, since the control means 35 has a light emission amount switching function for varying the light emission amount of the strobe section 50 for illuminating the subject to be photographed, the aperture calculated by the aperture limiting means 94 is calculated as follows: When the aperture is larger than a preset limit aperture to obtain a predetermined depth of field, the diaphragm is held at the limit aperture, and the amount of light emitted from the flash unit 50 is changed to
The object distance data obtained by the distance detecting means 18 and the limit aperture of the diaphragm are controlled to a value determined by the distance.

In this embodiment, the driving position for photographing the violating vehicle driven by the first photographing under the first setting condition shown in # 211 is maintained as it is, and the second setting is performed from this state. Although it is designed to be driven to a target position corresponding to the second shooting under the conditions, as indicated by the broken line # 218 in FIG. 15, the step # 2 is performed in parallel with the step # 213.
You may additionally provide # 217 which performs the intermediate position drive step similar to 15.

Therefore, in this embodiment, focus drive,
For each of zoom drive, aperture drive, and direction drive,
Since the intermediate position is driven prior to the drive to the target value, the amount of drive prior to shooting can be reduced, and the preparation time prior to shooting can be shortened. Along with this, the time lag between the shooting start command time (the time when the violating vehicle reaches the vehicle detection means 91) and the time when the shooting is actually started can be extremely reduced.

Further, based on the instruction of the aperture limiting means 94, the aperture value of the calculated aperture (aperture value of proper exposure) at each of the above-mentioned eight positions becomes such that the minimum depth of field cannot be secured. Sometimes, without using the aperture value of the computed aperture, I prepare for underexposure to some extent and try to shoot with the aperture value down to the minimum depth of field. Can be done.

Therefore, in this embodiment, for each of the focus drive of condition A, the zoom drive of condition B, the diaphragm drive of condition C, and the deflection drive of condition D, the intermediate position is set before the drive to the target value. Since it is driven to, it is possible to reduce the amount of drive prior to shooting, so that the preparation time prior to shooting can be shortened. Along with this, the time lag between the shooting start command time (the time when the violating vehicle reaches the first vehicle detection means 31 or the second vehicle detection means 32) and the time when the shooting is actually started is extremely reduced. You can do it.

The present invention is not limited to the above-mentioned four embodiments, and it goes without saying that various modifications can be made without departing from the scope of the invention. For example, the vehicle sensor as the vehicle detection means according to the present invention,
Not only the pressure sensing type but also other types such as a semiconductor sensor may be used.

Further, in the above-mentioned embodiment, the number of various preset data such as the aperture is eight, but it may be more or less, and the scale is such that the traffic condition photographing device is actually used. It can be arbitrarily designed according to the road conditions in the region. Furthermore, as for the detection of violation,
It can be used not only for ignoring signals, but also for shooting various violations such as overspeeding and railroad crossing suspension violations.

Further, the setting of the time t in the third and fourth embodiments can be designed completely arbitrarily according to the traffic situation. Further, the driving to the intermediate position in the second and fourth embodiments may be performed prior to the second shooting when the first shooting is completed, or the first and second shootings may be performed.
It may be performed when the second shooting is completed.

Further, the driving to the intermediate position in the above-mentioned second and fourth embodiments is carried out by changing the magnification, the turning, the focusing and the diaphragm.
Although it is performed for all three, the present invention is not limited to this, and the intermediate position driving for zooming or the intermediate position driving for turning can be omitted.
