Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photo-taking device with a self-monitor that is suitable for taking personal photos for albums, business cards, IDs, etc.

[Conventional technology]

Conventionally, still cameras such as general single-lens reflex cameras have been used to take photos of this type, and the photographer looks through the viewfinder, decides on the composition of the subject (the person in the case of portrait photography), selects the posture, and then takes the photo. are doing.

In addition, some remote-controlled cameras for bird watching etc. capture the camera's viewfinder image and display the shooting screen on a monitor TV, but the photographer still has to monitor the image, select the shutter settings, and then take the picture. There is.

Furthermore, although there are automatic photographing devices that allow users to take photographs for identification purposes without the need for a photographer, it is not possible to check the photographic screen before taking the photograph.

[Problem that the invention seeks to solve]

As described above, with conventional photographic devices, it is not always possible for the person who is the subject to monitor the screen being photographed and check and correct the composition, clothing, pose, etc. I couldn't take a good photo.

In particular, when taking photos of many people one by one, such as personal photos for school graduation albums, photos to be printed on business cards, or photos for ID cards at work, etc., each person It took a long time to prepare for shooting, which resulted in poor shooting efficiency.

Therefore, it is conceivable to install the monitor TV of the conventional remote control camera facing the person being photographed so that he or she can monitor the shooting screen himself, but this would not only make the device large-scale, but also involve the camera and the monitor TV. The subject (person)
The problem is that the subject's line of sight is far away from the camera, making it easy to end up with a photo of someone looking aside.

Furthermore, since the image on conventional monitor televisions is a right-left image, when you monitor it yourself, it does not look like you are looking at a mirror, and there is also the problem that it is difficult to correct the composition, pose, etc.

This invention aims to solve these problems.

[Means for solving problems]

Therefore, the self-monitoring photographing device according to the present invention includes a still camera and a television camera, each of which shoots or images a real image of a subject by selectively inputting the photographing light beam from a common photographic lens using a movable mirror, and the television camera. A monitor television for converting a video signal imaged by the camera into an image is provided in the same housing, and the photographing lens and the screen of the monitor television are placed in the front of the housing so as to face in the same direction.

Further, means for turning the image on the monitor television into a left-right inverted image with respect to the subject, and a remote control operation unit;
After moving the movable mirror by a switch operation of the remote control operation unit from a position where the photographing light beam from the photographing lens is made to enter the main body of the television camera to a position where it is made to enter the main body of the still camera,
The camera also includes means for opening and closing the shutter of the still camera body.

[Effect]

The photographic device with a self-monitor configured in this manner has a still camera and a television camera that share a common photographic lens, and a monitor television that displays the subject image captured by the television camera, all housed in the same housing. This makes it a single, compact device that is extremely easy to carry and set up.

The person who is the subject can monitor the image projected on the TV monitor screen without parallax, and can easily adjust the pose, etc., as if looking in a mirror, and the shooting lens and the TV monitor screen can be brought close together. Because I do this, the line of sight almost disappears.

Therefore, by confirming a preferred pose and the like and operating a switch on the remote control unit, the subject can easily take a photograph of himself or herself in a preferred pose using a still camera.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a self-monitoring photographing device according to the present invention, and FIGS. 2 to 4 are a front view, a rear view, and a right side view thereof.

A housing 1 of this device is composed of a front frame 3 of a bottom plate 2, a rear plate 4, and a cover 5.

Inside the protective glass 6 of the front frame 3, there is a photographic lens (a zoom lens is used in this example) 7 and a monitor TV screen (CRT surface) 8, which will be described later.
a are arranged close to each other facing the same direction. Reference numeral 9 denotes a photographing lamp that is turned on during photographing, and is arranged very close to the photographing lens 6. In addition,
The back surface of the protective glass 6 is printed in black as shown by diagonal lines in FIG.

A handle 10 is attached to the top surface of the cover 5 for gripping when carrying. Also, on the right side, as shown in Figure 4, there is a locking lid 1 that covers the film chamber into which the long film is loaded.
1 is removably attached, and a rotating lid 12 that covers a window for operating the photographic lens 7 is also hinged. Reference numeral 13 denotes an information card insertion slot into which an information card for identifying the person who is the subject is inserted.

As shown in Figure 3, the back plate 4 has an AC
Power supply connector 14, power circuit fuses 15, 1 for still camera and monitor TV power supply
6, 17, Synchro signal terminal 1 for strobe tuning
8. Multi-cable connector 19 for connecting the remote control, picture quality (contrast) of the monitor TV,
Volumes 25 to 25 for adjusting brightness, color density, hue, vertical synchronization, and horizontal synchronization, a film counter 26, and the like are provided.

The bottom plate 2 is provided with four rubber feet 27 and a screw hole for a tripod (not shown).

Next, FIG. 5 is a diagram schematically showing the internal device with the front frame 3 and cover 5 removed from this housing 1, and there is a reinforcing plate along the longitudinal direction in the center of the width direction and serving as a mounting plate. A partition plate 29 is provided.

On one side of this partition plate 29, a monitor television (color monitor television in this example) 30, a power supply circuit 41, a control circuit board 42, etc. are provided.
On the other side, in addition to the above-mentioned photographic lens 7, there are a mirror box 50, a film chamber 61 constituting the still camera body 60, a winding motor 62,
and a hoisting interlocking mechanism 63 that utilizes the driving force,
A film counter 26, a reduction lens barrel 71 constituting a television camera body 70, an imaging section 72 and its circuit board 73, a data imprinting section 80, and the like are provided.

Next, FIG. 6 shows the optical system and system configuration of this embodiment, and its operation will be explained using this figure.

A photographing light flux from a subject that enters through the photographic lens 7 is switched to a still camera main body 60 and a television camera main body 70 by a movable mirror 51. That is, the still camera main body 60 and the television camera main body 70 share the photographic lens 7, and constitute a still camera and a television camera, respectively.

When the movable mirror 51 is at a position inclined at 45 degrees with respect to the optical axis L of the photographic lens 7, as shown by the solid line in FIG. An aerial image (real image) is formed by a field lens 52 disposed equidistant from F.

Then, it is reflected downward by the fixed mirror 53 perpendicularly to the plane of the paper, and further reflected by the fixed mirror 54 at right angles to the left in the figure, so that it is reflected in the reduction lens tube 71 provided in the reduction lens barrel 71 in FIG. The above-mentioned aerial image is reduced by the small lens 74, and is imaged through a color filter 75 onto an imaging surface (light receiving surface) of a solid-state image sensor 76 using a CCD.

In this case, the image size of the still camera is reduced by the reduction lens 74, for example, 24
This is because the size of the imaging surface of the fixed image pickup element 76 is small, for example, 6.6 x 8.8 mm, whereas the size of the fixed image pickup element 76 is 6.6 x 8.8 mm.

Further, the path of the photographing light beam in this case and the arrangement relationship of the above-mentioned optical elements are shown three-dimensionally as shown in FIG. 7. The mirrors 51, 53, 54 and the field lens 52 are arranged in a mirror box 5 shown in FIG.
It is set within 0.

Again in FIG. 6, the solid-state image sensor 76 is
Driven by transfer pulses generated by a CCD drive circuit 77, video signals are sequentially read out, and a signal processing circuit 78 performs processing to create a luminance signal, a color signal, and a synchronization signal.
Output as an NTSC color video signal.

This color video signal is input to the video signal processing circuit 31 of the monitor television 30, where it undergoes processing such as amplification, synchronization separation, color demodulation, etc.
3 to a cathode ray tube (CRT) 8 to which a high voltage is applied to the anode, and a synchronization/deflection circuit 32 generates horizontal and vertical deflection signals and applies them to a deflection coil 8b.

Thereby, a subject image is projected on the screen 8a of the cathode ray tube 8. In this case, since the photographing light beam from the photographing lens 7 is reflected three times by the mirrors 51, 53, and 54 and is imaged on the imaging surface of the solid-state image sensor 76, the image becomes a left-right inverted image with respect to the subject, and is displayed on the monitor. The image displayed on the screen 8a of the television 30 is also a left-right reversed image.

Therefore, the person who is the subject can self-monitor the photographed screen as if looking in a mirror.

Next, when photographing, when the photographer or the person who is the subject presses the switch 91 of the remote control operation section 90, the photographing lamp 9 is first turned on by the action of the control circuit 42, and the solenoid 55 is activated to move the movable mirror. 51 is rotated to a position where it is retracted from the optical path of the photographing light beam as shown by a virtual line.

As a result, the subject image formed by the photographing lens 7 can be formed on the film surface F. Then, the focal plane shutter 64 opens,
When the shutter is fully open, the control circuit 42 generates a synchronization signal to cause an electronic flash (not shown) to emit light, a photograph is taken, and the shutter 64 is closed.

Thereafter, the motor 62 is driven, and the winding interlocking mechanism 63 winds one frame of the film and charges the shutter, and the count number of the film counter 26 is advanced by one.

Incidentally, in this embodiment, data for identifying the person who is the subject is simultaneously imprinted on, for example, the right edge of the film surface during the above-mentioned photographing.

Therefore, if an information card 81 on which identification data is written, for example, in the form of a bar code, is inserted into the information card insertion slot 13 shown in FIG. The illumination lamp 82 is turned on by 42,
The reflected light from the information card 81 is reflected on the lens 8
3, is reflected vertically upward by a first mirror 57 in a mirror box 50, and is further reflected vertically upward by a second mirror 57 in a mirror box 50.
reflected laterally at right angles by mirror 58,
It is reflected by the mirror 59 in a direction parallel to the optical axis L of the photographing lens 7, and is imaged on the right edge of the film surface F, on which identification data such as a bar code is imprinted.

FIG. 8 is a sectional view showing details of the main parts of the mirror box 50, the film chamber 60, and the data imprinting section 80. A lever 56 is movably supported on a shaft and has one end fixed to a shaft 51a, and its other bent end is connected to a rod of a solenoid 55, and is rotated by the insertion and removal of this rod.

Inside the film chamber 61 of the still camera body, a pair of spools 65 for supplying and winding the film are inserted into spool shafts (not shown), and a long film 66 wound around the spools 65 is guided through the film guide section. Focal plane by 67
Guided by the distance between the shutter 64 and the pressure plate 68, each frame is photographed.

Further, the data imprinting section 80 is provided with a guide plate 84 having a window 84a that guides the information card 81 and exposes only the data section thereof. In addition,
In this FIG. 8, the second and third mirrors 58 and 59 are not shown.

FIG. 9 shows an example of the arrangement when taking a photograph using this self-monitoring photographing device.

A photographic device 100 with a self-monitor is placed on a stand (or a large tripod) 101, and a chair 102 and the required number of electronic flashes EF ₁ -
EF ₄ is placed, and the zoom ratio and focal length of the photographic lens are set in advance to optimal values when a person is sitting on the chair 102. The shutter speed of the still camera is fixed at the flash synchronization time (for example, 1/60 sec).

When a person 103 to be photographed sits on a chair 102, the same screen as the photographic screen is displayed on the monitor television 10 with left and right reversed images, allowing self-monitoring without parallax. Then, correct the composition, pose, etc., and if it is OK, use the remote control operation section 9.
If you press the 0 switch, shooting will begin.

At this time, since the photographing lamp 9 is turned on, the person's line of sight is drawn to it and directed toward the photographing lens 7, so that it is possible to further prevent the person's line of sight from becoming distorted.

In the above embodiment, the photographing light flux is switched between the still camera body and the TV camera body using a movable mirror, but if a large number of lamps are used to illuminate the subject and a sufficient amount of light is always obtained, Alternatively, a half mirror, a beam splitter, or the like may be used to split the photographing light beam into two and make it always enter the still camera body and the television camera body. In this way, you can monitor the image even while shooting.

In addition, we have made it possible to take pictures of many people in succession by using a camera that uses long film as a still camera, but when using it as an automatic photographing device for ID photos etc., instant film can be used. This should be the camera you use.

Further, although a mirror group of three mirrors is used as a means for turning the image on the monitor television into a left-right reverse image of the subject, the number of mirrors is not limited to three, and may be reflected an odd number of times. Further, by reversing the main scanning direction (horizontal scanning direction) of the imaging surface of the television camera or the imaging surface of the monitor television, it is also possible to electrically create left-right reversed images.

The imaging unit of a television camera is not limited to one that uses a solid-state imaging device, but may also be one that uses an imaging tube, and is not limited to a single-panel or single-tube type, but one that uses multiple imaging devices or imaging tubes. Of course, it is possible.

If data for identifying the subject can be imprinted as in the above embodiment, for example, when editing or plate making when creating an album, or when reprinting business cards with photos, etc. It is convenient to be able to search automatically.

〔Effect of the invention〕

The self-monitoring photographing device according to the present invention has a still camera, a television camera, and a monitor television that share a photographic lens, housed in the same housing, so it can be constructed extremely compactly and at low cost. It is easy to transport, and extremely easy to set up and operate.

By using this device, the subject can monitor the shooting screen without parallax while watching the TV monitor himself, and since the image is reversed left and right, he can pose and pose as if he were looking in a mirror. You can change your clothes, etc., and since the monitor TV and photographic lens are close together, there is almost no line of sight.If you decide on the desired pose on the monitor screen and press the switch on the remote control unit, the movable mirror will change. Suddenly, the shutter on the still camera was activated, and I was able to take the same desirable photo as the one on the monitor screen in a short time.

Therefore, the photographing efficiency can be greatly improved in situations where photographs of a large number of people are taken one by one.

In addition, since it is easy to transport, you can easily carry it anywhere for business trip photography. Furthermore, it is easy to set up a simple studio in a car, for example, and immediately go to work or school and take pictures.
