Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a photographing device suitably used for photographing moving objects such as railway vehicles and automobiles.

Problems to be Solved by Conventional Technologies and Inventions For example, when photographing a railway vehicle, a method called slit photography has been used to photograph the details of a horizontally long vehicle or to capture a sense of movement. is used.

This method involves placing a shielding plate with slits formed at extremely small intervals in front of the film, opening the shutter curtain, and as the subject passes by, reversing the so-called motor drive device to continuously wind the film. This is a method of photography that continues to evolve. This makes it possible to capture the details of the vehicle in the longitudinal direction of the film, and the stationary background appears as a striped pattern that extends along the winding direction of the film, creating a sense of dynamism similar to what is known as a panning shot. can do.

However, with such slit photography, it is very difficult to form slits in the shielding plate and attach the shielding frame to the camera. In addition, in order to obtain an appropriate exposure amount, the aperture must be set according to the weather, film sensitivity, or winding speed of the film 11, and accumulated experience and intuition are important factors. It is difficult to always take stable photographs.

Furthermore, it is difficult to accurately photograph the aspect ratio of an actual vehicle. In other words, for example, as the film is wound, the diameter of the film increases and the winding speed becomes faster.If the moving speed of the vehicle is constant, the actual image taken will change from the front vehicle to the rear vehicle. Similarly, the aspect ratio of a vehicle changes when the length of the vehicle becomes shorter, the speed of the vehicle changes, or the focal length of the lens changes even at the same shooting location.

On the other hand, in the case of railway vehicles, such as SL trains, the number of trains in operation is limited, and it is not unusual for there to be few opportunities to take photographs.Therefore, if you want to photograph the same subject in different compositions, you may need to use multiple cameras.

FIG. 3 is a diagram for explaining a method of taking a slit photograph. ! In FIG. 3, the viewer determines the composition so that, for example, the area indicated by reference numeral 81 appears within the finder 8. When the slit photography mode is selected by operating the slit photography key 28 and the release switch 21 is operated, the leading and trailing curtains of the shutter curtain 4 are separated by a predetermined interval Wt while the release switch 21 is being pressed. At the same time, the motor 32 is driven and the film 5 is continuously wound.

At this time, the winding speed of the film 5 is adjusted so that the subject 3 reflected on the surface of the film 5 and reflected on the image sensor 36
The processing circuit 13 controls the rotational speed of the motor 32 so that it becomes equal to the moving speed of the motor 32 .

Further, the processing circuit 13 controls the opening degree of the diaphragm 2 in accordance with the winding speed so that appropriate exposure can be obtained. Note that depending on the winding speed, exposure adjustment may not be possible only by the opening of the aperture 2, and in this case, the interval W1 is adjusted.

Furthermore, the winding speed is determined by the image sensor 36 as described above.
If the speed is equal to the moving speed of the subject 3 above, the aspect ratio of the subject 3 can be accurately reproduced on the film 5, but if you want to expand or contract this aspect ratio, you can adjust the aspect ratio as desired using an input means (not shown). By inputting the aspect ratio, the winding speed is automatically set to correspond to that aspect ratio. In this way, a slit photograph with an accurate aspect ratio and appropriate exposure can be easily and reliably taken.

Further, similar to the slit photography shown in FIG. 3, after the shutter curtain 4 is stopped at a predetermined position within the travel range to form a slit, the film 5 is wound up and the movable pan head 61 is horizontally rotated. In this way, panoramic photography can be performed.

At this time, corresponding to the slit interval W1 and the aperture value,
At least one of the winding speed of the film 5 and the rotational speed of the movable pan head 61 is controlled to obtain proper exposure. Alternatively, the slit may be formed after the movable pan head 61 rotates and starts running up.

According to such panoramic photography, it is possible to obtain an image without distortion that occurs when a short focus lens is used in a normal camera.

Note that the above-mentioned slit photographs and panoramic photographs can also be taken with a video camera or a magnetic disk camera. In this thirst, in an imaging means such as an image pickup tube or an image sensor, a predetermined area that intersects with the moving direction of the subject 3,
That is, only the video signal of the optical image of the area corresponding to the interval W1 of the slits is 31! Record continuously.

At this time, the interval W1 between the predetermined areas is determined in accordance with the moving speed of the optical image on the image pickup element, and when the optical image is sequentially converted into a video signal, the distance W1 between the predetermined areas is Only the part following the photographed part is converted. That is, the same part of the subject 3 is prevented from being photographed repeatedly. This allows the aspect ratio of the subject to be accurately reproduced. Alternatively, the interval W1 may be kept constant and the conversion speed from an optical image to a video signal may be varied to prevent the same portion from being photographed repeatedly.

Slit photographs and panoramic photographs taken in this manner can be reproduced as photographs using a video printer or the like, and can also be reproduced on a television screen after being subjected to image processing using a microcomputer or the like.

FIG. 4 is a diagram for explaining the automatic photographing method. After operating the program switch 23 and selecting a scene number, the photographer adjusts the movable pan head 61 and operates the up/down switch 22, autofocus switch 24, automatic exposure switch 25, shutter speed switch 26, etc. For example, in FIG.
A composition and photographic data as shown in are determined and stored in the memory 51. Perform the same operation and use reference mark 84.
．． The compositions are determined as shown at 85 and are stored together with the photographic data for each composition.

Note that this shooting data includes settings for actually storing the focal length, focus, aperture value, shutter speed, etc. of the lens 20, and settings for storing these during actual shooting, such as the automatic exposure mode and autofocus mode. Any settings you decide can be stored.

The photographic data stored in this way is read out when the release switch 21 is operated in the automatic photographing mode, and when the release switch 21 is fully pressed or half-pressed, the data is of the same scene. When the release switch 21 is once set and then pushed in again, the next scene is read out, and each part is driven to match the read data.

Therefore, even when there is little time to change the composition or various settings, such as when continuously photographing a moving subject, it is possible to reliably capture the scene that the photographer intended. , you can make effective use of photo opportunities. Further, with one camera 1, it is possible to efficiently take pictures with different compositions, and the labor for transporting the equipment can be reduced.

FIG. 5 is a diagram for explaining another automatic photographing method. During automatic photography shown in FIG. 5, the LCD 55, which is located at the position indicated by reference numeral 55a in FIG. A pointer indicated by reference numeral 78 is displayed.

After setting the composition shown in FIG. 5(1) and the shooting data such as focus and aperture value, the photographer operates the pointer movement key 27 to move the pointer on the display screen of the finder 8, By operating the program switch 23, the shutter release positions are set in advance in the processing circuit 13, as indicated by reference marks A, B, and C.

When the release switch 21 is pressed and held with the shutter timing set in this way, as the subject 3 moves on the image receiving surface of the image sensor 36, the processing circuit 13 changes from FIG. As shown in 4), the shutter is released at each timing indicated by reference marks A, B, and C.

In this case, when the release switch 21 is pressed down, the so-called motor drive continuously takes pictures as in 1 normal shooting, but the image sensor 36
From the moving speed of the subject above, at least the reference mark A,
Control is performed so as not to miss photographing at the shutter timings indicated by B and C.

That is, in FIG. 5(1), the shutter is released at the position indicated by the reference mark A, and then the shutter is released successively at the positions indicated by the reference marks A1 and A2, and then the shutter is released at the position indicated by the reference mark A3.
When the shutter is released at the position indicated by reference mark B, if the film is not advanced or the shutter charge is completed in time for the next photograph at the position indicated by reference mark B, this reference mark ? ! fA3
The photographing at the position indicated by is stopped, and the photographing at the predetermined position indicated by the reference mark B is given priority.

In this way, the moving subject 3 can be reliably photographed at an in-progress timing.

Note that the focusing at this time may be performed in advance at each point A, BC and stored in the processing circuit 13, or by setting the autofocus mode, each point A, B, It may be configured to be performed at the actual passing point of C.

Furthermore, in combination with the automatic photographing shown in FIG. 4, the shutter release position may be set in advance for each composition.

Furthermore, as shown in FIG. 5, the shutter release position may be set in advance, and when the subject 3 reaches this position, the shutter will be released and the strobe will fire in synchronization. good. In this case, the main body 10
Alternatively, a strobe may emit auxiliary light such as infrared light for focusing.

Thereby, even in darkness, it is possible to reliably photograph the subject 3 at a desired shutter timing.

FIG. 6 is a diagram for explaining still another automatic photographing method. The photographer determines the composition and focus as shown by the reference mark 86, sets the desired shutter speed in advance from the shutter speed switch 26, and then sets the desired shutter speed using the reference mark 86 in the same manner as in FIG. , E, the front position and/or rear position of the subject 3 is registered in advance.

When the release switch 21 is pressed halfway in this state, the movable pan head 61 changes the composition to the position indicated by reference numeral 87 and stands by. Note that when the release switch 21 is released from being pressed halfway, the standby state is canceled. When the subject 3 enters the screen in this standby state, the processing circuit 13
Detecting and storing the moving speed on the image sensor 36 of
When the forward position of the subject 3 reaches point D on the image sensor 36, the movable pan head 61 starts running up at a rotational speed corresponding to the moving speed of the subject 3.

When the composition reaches the position indicated by reference numeral 86, the shutter curtain 4 is opened for a period corresponding to a preset shutter speed, and eventually a so-called panning shot is performed up to the position indicated by reference numeral 88. When the shutter curtain 4 is closed, the movable pan head 61 adjusts the composition as described above. J reference mark 8
Return to the position indicated by 7 and wait. Also, film and shutter charging are performed.

When the release switch 21 remains depressed, when the rear position of the subject 3 (not shown) reaches point E,
The moving speed on the image sensor 36 is detected and stored again, and the movable pan head 61 starts running up. Thereafter, in the same way as described above, when Figure #1 reaches the position indicated by reference numeral 86, the shutter curtain 4 is opened for a period corresponding to the shutter speed to perform a panning shot.

Further, when the shutter timing indicated by the reference mark E on the display screen of the finder 8 is not set, the photographer changes the composition to follow the subject 3 and presses the release switch 21.

As a result, the processing circuit 13, based on the set value of the shutter speed, from the moment this release switch is pressed,
The shutter is released when the blur of the subject 3 on the image sensor 36 becomes the smallest.

However, if the above condition is not satisfied even after a predetermined time, for example one second, has elapsed since the release switch 21 was pressed, the shutter is released at the point in time when that time has elapsed. At this time, the shutter speed is set to the slowest speed among the speeds at which the subject 3 does not blur. In this way, it is possible to perform accurate flow-off without blurring as shown in FIG.

Note that the rotation speed of the movable pan head 61 is not made to completely match the moving speed of the subject 3 as described above, but is made to match only for a portion of the opening period of the shutter curtain 4, for example, immediately after opening or just before the end of opening. By doing this, it is possible to obtain an effect similar to so-called rear-curtain synchronization, and as shown in FIG. Other parts can be depicted with a flow.
