Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera adapter, such as a video camera or a still camera using a silver salt film, in which a convex mirror for projecting an object is arranged in the vicinity of a photographing lens and the convex mirror can be used as a finder. .

[0002]

2. Description of the Related Art For example, a video camera in which a camera unit having a photographing lens and the like is rotatable on a monitor side for photographing is disclosed in Japanese Utility Model Laid- Open No. Sho 63-178962. This will be described in detail with reference to FIGS. 34 and 35. Reference numeral 100 denotes a video camera, which has a color liquid crystal panel (LCD) 102 and a VT on the back side as a monitor.
The VTR main body 101 equipped with the R deck section 103, and this V
The rotary knob 1 is provided in the recess 101a in the upper portion of the TR body 101.
The camera body 104 is rotatably supported in the front-rear direction via a lens 05 and the like, and includes a camera body 104 having a lens barrel 104a including a taking lens 106 and a CCD.

The color liquid crystal panel 102 is displayed on the color liquid crystal panel 102 when the camera body 104 is oriented in the same direction (front side) as the color liquid crystal panel 102 and an image of oneself is taken as a subject (self-produced). The image of the subject to be displayed is reversed, and it is configured as if looking at it in a mirror surface. That is, as shown in FIG. 35 (b), by using the lens barrel 104 a of the camera body 104 facing forward, it is possible to project oneself on the color liquid crystal panel 102, which is used as a mirror. . Further, as shown in FIG. 35A, when performing normal shooting, the lens barrel 104a of the camera body 104 is directed forward. As a result, the subject to be photographed is displayed on the color liquid crystal panel 102 of the VTR main body 101, and the subject is recorded on a magnetic tape of a tape cassette (not shown) in the VTR deck section 103.

[0004]

In the conventional video camera 100 described above, the display of the color liquid crystal panel 102 is reversed and the image is viewed as if it were a mirror surface, for example, when taking a picture of oneself by a self-made performance. I am
Since a mechanism including a rotary knob 105 for rotating the camera body 104, a circuit for reversing the sweep of the color liquid crystal panel 102, and an LCD dedicated for reversing are required, the cost is high and the above-mentioned mechanism and circuit are required. An extra space was required to assemble it, making it impossible to reduce the overall weight and size.

Further, as shown in FIG. 35B, when the image is taken while the image of oneself is shown on the color liquid crystal panel 102 with the lens barrel 104a of the camera body 104 facing forward, the image of the taking lens 106 is taken. Since there is a distance between the position and the position of the color liquid crystal panel 102 used as a finder, there is a difference between the range visible on the color liquid crystal panel 102 and the range photographed (recorded) on the tape cassette in the VTR deck 103. This caused parallax (a phenomenon that occurs because the optical axis of the finder optical system and the optical axis of the taking lens are separated). As a result, when taking a picture of oneself as a subject, the line of sight becomes out of focus without taking the direction of the photographing lens 106, and when it is reproduced, a so-called "eyes-off" shape is formed. I felt something like a sense of harmony.

Therefore, the present invention makes it easy and reliable to take self-photographs.
To provide a camera adapter that can be done really
With the goal.

[0007]

[0009]

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

1-3, 1A shows a video camera as the camera of the first embodiment. This video camera 1
In A, the grip portion on the right side of the camera body 2 having a substantially rectangular parallelepiped shape is a VTR deck section 2a for recording an object on a magnetic tape of a tape cassette (not shown), and the state of the object being recorded is displayed on the upper left side. An electronic viewfinder 3 for checking is provided. In addition, a microphone 4 is provided on the upper front side of the camera body 2, and
On the lower left side thereof, there is a taking lens 5 and an image pickup device (C
A cylindrical lens barrel 6 having a built-in CD, etc. is provided in a protruding manner. Further, a zoom button 7 is provided on the rear side of the upper surface of the camera body 2, and a photographing start / stop button and a battery 8 (not shown) are provided on the back surface of the camera body 2.

As shown in FIGS. 1 and 2, a shooting start / stop button (shooting button) 9 for self-shooting is provided on the lower right side of the front surface of the camera body 2. The photographing start / stop button 9 is moved by moving the zoom lens including the photographing lens 5 to the wide end (full-angle state) side by the first pressing operation, and then recording is started. The recording is stopped. The outer surface of the lens (front lens) on the outermost side of the taking lens 5 of the lens barrel 6 is formed into a convex spherical surface, and the half mirror 10 is formed on this convex spherical surface by means such as vapor deposition. As a result, the outer surface of the front lens of the photographing lens 5 is a half-mirror-shaped convex mirror 10, and when the photographing start / stop button 9 for self-photographing on the front surface of the camera body 2 is operated, the figure of oneself becomes the subject. It is supposed to be projected as. The half mirror-shaped convex mirror 10 reflects a part of external light and allows the rest to enter the lens barrel 6 from the taking lens 5.

In FIGS. 1 and 2, reference numeral 3a is a tally lamp provided in the viewfinder 3. Also, since the video camera 1A has higher sensitivity than the still camera,
Even if the outer surface of the front lens of the taking lens 5 of the lens barrel 6 is formed as the half-mirror-shaped convex mirror 10, it is possible to take an image outdoors or in a normal indoor environment.

According to the video camera 1A of the above embodiment,
As shown in FIG. 3, for example, when a person traveling alone wants to take a picture of himself or herself, the video camera 1A
Change to the left hand and shoot with the lens barrel 6 side facing you. At this time, since the outer surface of the front lens of the taking lens 5 of the lens barrel 6 is the half-mirror-shaped convex mirror 10, as shown in FIG. Since the image is displayed as A, the convex mirror 10 can be used as a finder, and the person to be photographed can check the position (imaging state) on the screen of himself / herself. Then, by pressing the photographing start / stop button 9 with the thumb of the left hand, one can photograph himself / herself. When the shooting start / stop button 9 is pressed, recording is started once the zoom of the video camera 1A becomes full wide angle. For this reason, it is possible to record without recognizing that the zoom is in the telephoto state so that only a part of the face is captured, and it is an excellent effect that anyone can easily capture it.

Further, the half mirror-shaped convex mirror 10 used as a finder is formed on the outer surface of the front lens of the taking lens 5 of the lens barrel 6, and the optical axis (axial center) of the finder optical system and the taking lens. Since the optical axis (axial center) of 5 matches, parallax does not occur. As a result, when a self-photographed image is played back, there is no shift in the line of sight as in the conventional case, and good self-photographing without discomfort is possible. In addition, a video camera without a monitor, such as a large color LCD panel 1
Even in A, self-photographing can be performed easily and surely.

4 and 5 show another mode of the convex mirror 10 of the video camera 1A of the first embodiment. This convex mirror 1
At 0, a rectangular annular image frame 10a as a screen frame is printed (marked). The size of this frame 10a is
The video camera 1A is formed to have a size that is substantially the same as or slightly smaller than the size of the image shot in the wide-angle full state (wide end) of the video camera 1A (screen displayed on a TV monitor or the like during reproduction).

As shown in FIG. 5, when taking a picture of oneself as the subject A, the position on the screen can be confirmed by the image frame 10a of the convex mirror 10 having a half mirror shape. Since the horizontal and vertical lines of the subject A can be known, more reliable shooting can be performed. However, the amount of light entering the photographing lens 5 is reduced by the amount hidden by the marking of the image frame 10a, but this has no effect on photographing.

6 to 8, 1B shows a video camera as a camera of the second embodiment. This video camera 1
B shows a VTR deck 2a on the right side of the substantially rectangular parallelepiped camera body 2, an electronic viewfinder 3 on the upper left side, a microphone 4 on the upper front side, and a taking lens 5 and not shown on the lower left side thereof. A cylindrical lens barrel 6 having a built-in image pickup device (CCD) and the like is provided with a zoom button 7 on the rear side of the upper surface.
Is the same as the first embodiment in that the battery 8 is provided on the back side, and the shooting start / stop button (shooting button) 9 for self-shooting is provided on the lower right side of the front side.

a is formed. As shown in FIGS. 6 and 7, the convex mirror 20
When the lens barrel 6 is screwed into the lens barrel 6, the optical axis (axial center C _B ) of the convex mirror 20 used as a finder and the optical axis (axial center C ₀ ) of the taking lens 5 are formed so as to be completely aligned with each other. I am doing it. This prevents parallax from occurring. An image frame 22a is printed on the surface of the half mirror 22 of the convex mirror 20. This image frame 22a is
The size of an image B (image reproduced on the TV monitor shown in FIG. 8) taken by the video camera 1B is shown. The position of the image frame 22a of the half mirror 22 is such that the half mirror 22 is attached to the ring 2 after the convex mirror 20 is screwed onto the lens barrel 6.
It can be adjusted to the correct position by rotating it with respect to 1.

Then, as shown in FIG. 8, when the video camera 1B is fixed to the tripod S and an image of oneself is taken, the convex mirror 20 attached to the lens barrel 6 of the video camera 1B is attached to the own mirror. The figure is displayed as a subject B, and the shooting start / stop button 9 on the front surface of the camera body 2
You can take a picture of yourself by pressing. At this time, since the optical axis (axial center C _B ) of the convex mirror 20 and the optical axis (axial center C ₀ ) of the taking lens 5 are completely aligned with each other, no parallax occurs. As a result, when a self-photographed image is played back, there is no shift in the line of sight as in the conventional case, and good self-photographing without discomfort is possible. Further, as shown in FIG. 8, the image frame 22a of the half mirror 22 of the convex mirror 20 can confirm the position of the subject B on the screen, that is, the photographing state, and the horizontal line and the vertical line of the subject B can be known, so that the subject B is more reliable. It is possible to shoot. However, the amount of light entering the photographic lens 5 is reduced by the amount hidden by the marking of the image frame 22a, but this has no effect on the photographing.

9 and 10, each optical system of the taking lens 5 and the convex mirror 20 used in the second embodiment will be described. FIG. 9 shows the optical system of the taking lens 5, and FIG. 10 shows the convex mirror 20.
Shows the optical system of. In the optical system of the taking lens 5, the distance from the inverted real image (CCD surface) L ′ to the taking lens 5 is v, the distance from the taking lens 5 to the upright real image (L) is u,
The focal length of the taking lens 5 is f, in the optical system of the convex mirror 20, the distance from the erecting virtual image to the convex mirror 20 is v ₀ , the distance from the convex mirror 20 to the erecting real image (L ₀ ) is u ₀ , and the convex mirror is Assuming that the focal length of 20 is f ₀ and the magnifications are m and m ₀ , respectively, v = f / {1+ (f / u)} (1) v ₀ = −f ₀ / {1+ (f ₀ / u) } (2) m = v / u (3) m ₀ = v ₀ / u ₀ (4) When u = u ₀ , m / m ₀ = f / f from the equations (1) to (4)
It becomes ₀ .

As a result, the ratio of the dimensions of the screen frame of the convex mirror 20 and the screen frame of the CCD is the ratio of the lengths of the focal lengths of the convex mirror 20 and the taking lens 5. It can be seen that a larger mirror image can be obtained by increasing the radius of the convex mirror 20.
