[Industrial applications]

 TECHNICAL FIELD The present invention relates to a stereoscopic mirror device for a video recorder used for stereoscopic shooting and reproduction video stereoscopic vision in various video recorders such as video cameras.

[0002]

[Prior art]

 In general, the stereoscopic effect that the eyes perceive a sense of perspective is due to the action of converging the sight lines of both eyes to the target, that is, the convergence, in addition to the adjusting action of focusing on the target, while many things at different distances are involved. If you look at at the same time, you can get a stereoscopic effect as a whole by recognizing each distance at the same time without looking at each individual. This is because the relative position of the image on the retina looks different between the left and right eyes due to the difference in distance, which is called binocular parallax. Therefore, various binocular parallax techniques and methods are provided, which are composed of a pair of photographs and video images that produce parallax by utilizing such binocular parallax, and have a long history. A wide variety of methods have been devised and implemented by our predecessors.

That is, a binocular stereoscopic image method that uses binocular parallax in which the same images as the two images viewed by the left and right eyes are separately given to the left and right eyes, and they are fused to give a stereoscopic effect. There is a 3D image system that realizes the property that when you actually look at an object, you can see it until you can see it by turning your eyes to the left, right, up and down. In addition, as a 3D display, there are two types of peep glasses that give two eyes two slightly different images using lenses and mirrors to give a stereoscopic effect, and red and blue (green) filter glasses. There is an anaglyph system in which you can see a parallax image printed in red and blue, and as a stereoscopic TV, you can wear vertical and horizontal polarizing glasses, and also use two polarizing images projected through a polarizing filter. Polarization method for viewing images with parallax, time-sharing method for alternately viewing the left and right images on a cathode ray tube, and wearing eyeglasses on the eyes that open and close alternately in synchronization with this, with vertical slits There are various types such as the parallax stereogram method in which the left and right eyes see the left and right eye images vertically arranged on the screen through a parallax barrier.

In particular, as a technique of a two-lens type stereoscopic image system, a stereoscopic photograph equipped with two photographic lenses from the beginning is used instead of a stereoscopic photograph for stereoscopic recognition and perspective recognition with a stereoscopic view. There is a method of obtaining a stereoscopic photograph using a machine. At this time, the size of the stereoscopic view is related to the base line length, which is the distance between the two lenses, and the larger the distance between the two lenses is, the wider the stereoscopic view is. In general, the size of the stereoscopic field of view as a range in which perspective can be discriminated is related to the size of the binocular distance (the size of the light angle), and the larger the binocular distance, the wider the stereoscopic field of view. In other words, the expansion of the range of the stereoscopic field of view is determined by the total magnification of the lens, which is the baseline magnification of the ratio between the distance between both lenses (baseline length) and the binocular distance, and the magnification m by the lens system. Is done. Therefore, in response to such various stereoscopic photography methods, there are many combinations with various stereoscopic reproduction methods (viewing) for stereoscopic viewing.

[0005]

[Problems to be solved by the device]

 However, in the above-described conventional technique, the combination itself between various stereoscopic photographing methods and various stereoscopic reproduction methods (viewing) is very complicated and impractical. Furthermore, the stereo camera has drawbacks such as complicated equipment such as having two photographic lenses, complicated operation thereof, and bulky price. Therefore, the currently popular stereoscopic devices for consumer (general) television viewing are extremely expensive, and the equipment is not easy to handle. There are too many factors that have not been disseminated and have not been realized.

Therefore, the present invention has been devised in view of the above-mentioned various existing circumstances, and mainly uses various video recorders such as a video camera which is very popular in general. 3D video recording can be easily recorded at low cost, and among them, stereoscopic viewing can be easily performed during playback after video recording, and the number of parts is extremely small and the structure is simple. Therefore, it is an object of the present invention to provide a stereoscopic mirror device for a video recorder, which is lightweight, compact, and excellent in portability.

[0016]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, the present invention is applied to both stereoscopic shooting and playback video stereoscopic viewing of a video recorder V such as a video camera. Reference numeral 1 shown in the figure is, for example, a trapezoidal box-shaped (a large size or an ophthalmic-type ultra-small size may be used, and may be configured to be waterproof and waterproof for underwater photography). (Commonly called 3D mirror). According to the illustrated example, the reflecting mirror housing 1 itself has a trapezoidal box shape in which diagonal side plates 9 are connected to the left and right sides of a substantially trapezoidal upper and lower side plate with a large front part and a small rear part. The object is formed through a front window 4 which is a rear opening and can be viewed through a front opening directed toward the object. Inside this 1, a secondary reflecting mirror body 5 described later slides back and forth. It is enabled and stored. The angle at which the rear edge of the oblique side plate 9 itself extends and intersects is approximately 90 degrees, and the primary reflecting mirrors 8A and 8B, which will be described later, are disposed on the inner surface of the oblique side plate 9. The primary subject image, which is a reflected image, is set so as to extend diagonally forward toward the center side of each other.

Further, since the entire housing of the reflector housing 1 is made of synthetic resin, aluminum light metal or the like, it can be handled as a lightweight one and easy to handle. Further, a mounting member 3 for mounting on the tripod mount 2 is additionally formed at the center of the lower part of the housing, and as shown in FIGS. 2 and 3, the mounting member 3 is mounted on the rear part of the mount base formed on the tripod mount 2. Also, it is positioned in front of the lens of the video recorder V and is also detachably attached to the front part of the mount.

A rectangular viewing window 4 for the video recorder V is opened in the center of the rear part within the binocular distance range of the reflector housing 1. A prism type in which a pair of left and right secondary reflecting mirrors 5A and 5B are attached to the outside at a bending angle of 90 degrees so as to oppose and match the left and right eyes in a range that can be viewed through the viewing window 4 in the approximate center of the area. The secondary reflecting mirror body 5 is installed, and the back-and-forth movement adjusting knob 6 mounted on the upper side of the secondary reflecting mirror body 5 is loosely fitted in the long slot 7 formed in the upper side plate of the reflecting mirror housing 1. This allows it to be slid back and forth and fixed in the suspended state. That is, by sliding the secondary reflecting mirror body 5 through the back-and-forth movement adjusting knob 6, it is possible to select the capture screen and adjust the viewing image so that there is no unnecessary light (Fig. 1, FIG. 4 and FIG. 5).

It should be noted that the secondary reflecting mirror body 5 itself has left and right slanted side plates in which the rear portions intersect at approximately 90 degrees, and the secondary reflecting mirrors 5A and 5B are arranged on the outer surface, respectively. The front end plates of the side plates are connected to each other, and the front plate located on the front surface, the upper and lower triangular upper and lower triangular side plates are formed into a triangular prism-like substantially prismatic prism shape. And a sliding guide through an engaging slide portion having a dovetail groove, a T-shaped groove and the like formed on the lower surface of the upper side plate of the reflector housing 1. In some cases, although not shown, the secondary reflecting mirror body 5 may have an engaging slide structure by being placed on the upper surface of the lower plate of the reflecting mirror housing 1. It is possible.

In addition, the left and right symmetric oblique side plates 9 which are separated by a predetermined interval outside the binocular distance range of the reflector housing 1, each of the secondary reflectors 5A of the secondary reflector body 5, 5B, a pair of primary reflecting mirrors 8A and 8B, which are obliquely directed to the object viewed through the front opening of the reflecting mirror housing 1, are installed to face each other (see FIG. 1). The primary reflecting mirrors 8A and 8B are pressed and supported by screwing the supporting screws 10 screwed into the four corners of the oblique side plate 9, and the axial rods 11 fixed to the centers of the primary reflecting mirrors 8A and 8B. Through a slotted hole 12 formed in the oblique side plate 9, and further through a washer 13 that abuts the outer side surface of the oblique side plate 9, and a coil spring 14 is wound to interlock it with a knob 15. is there. That is, with respect to the urging of the both primary reflecting mirrors 8A and 8B to the oblique side plate 9, the pressing accompanying the screwing by any one of the pair of supporting screws 10 at the four corners from the outside of the reflecting mirror housing 1 or its pressing. By releasing the pressing (see FIG. 9), both the primary reflecting mirrors 8A and 8B are tilted at a predetermined angle with respect to the secondary reflecting mirrors 5A and 5B, respectively, so that either the left or right primary reflecting mirror is at least one side. The angles of 8A and 8B can be made relatively variable (see FIGS. 1 and 8). At this time, the screwing forward movement of the pair of upper and lower support screws 10 on the front portion sets the reflection angle of the primary subject image by the primary reflecting mirrors 8A and 8B to a negative angle smaller than 90 degrees, and conversely, on the upper and lower portions of the rear portion. The screwing forward movement of the pair of support screws 10 sets the reflection angle of the primary subject image by the primary reflecting mirrors 8A and 8B to a plus angle larger than 90 degrees. Further, by sliding the knob 15 along the long slot 12, the primary reflecting mirrors 8A, 8B on at least one side of the secondary reflecting mirrors 5A, 5B are moved in parallel forward and backward relative to each other. As a result, the peep width (convergence) is secured and the eye-gaze effect is obtained (see FIGS. 1 and 7).

Therefore, the primary subject images reflected by the left and right primary reflecting mirrors 8A and 8B arranged on the inner surface of the oblique side plate 9 of the reflecting mirror housing 1 with the front opening facing the subject are The image is obtained as left and right secondary subject images that are reflected again by the left and right secondary reflection mirrors 5A and 5B in the secondary reflection mirror body 5 in the inside of the unit 1. The secondary subject images are the subject images of the single subject, which are two different left and right images in which binocular parallax is generated, which are separated by a predetermined left and right intervals. The image reflection path passing through 4 is divided into left and right parts and formed separately. That is, the reflection path of the subject image on the left side is first reflected by the left side primary reflection mirror 8A by each of the left side primary reflection mirror 8A and the secondary reflection mirror 5A which are arranged in front and back, It is reflected again by the left secondary reflecting mirror 5A located diagonally forward of the center side, passes through the left side of the viewing window 4, and, for example, in the video recorder V arranged behind the viewing window 4 at the time of shooting video recording. The image is recorded on the left side of the image screen, or at the time of reproduction, the reproduced image is incident on the viewer's left eye side behind the viewing window 4. Similarly, the reflection path of the subject image on the right side is first reflected by the primary reflection mirror 8B on the right side by the primary reflection mirror 8B on the right side and the secondary reflection mirror 5B arranged in pairs on the front and rear sides. , Is again reflected by the right side secondary reflecting mirror 5B located diagonally forward of the center side, passes through the right side of the viewing window 4, and when the video recording is performed, for example, an image in the video recorder V arranged behind the viewing window 4 The image is recorded on the right side of the screen, or at the time of reproduction, the reproduced image is incident on the viewer's right eye side behind the viewing window 4. These left and right captured images and reproduced images themselves are obtained by dividing the left and right in the same screen, and there is binocular parallax between the divided screens.

It should be noted that the angle adjustments of the primary reflecting mirrors 8A and 8B and the size of the reproduction screen such as a display screen of a television set are set to have a correlation with each other, and the vertical / horizontal size ratio is 4 :. It is good to make it correspond to the normal screen of 3 or the so-called high-definition or wide screen of 9:16. If necessary, by forming the primary reflecting mirrors 8A and 8B themselves as convex mirrors, it is possible to deal with a horizontally long screen that is long in the left and right directions, and it is possible to obtain even greater realism.

In addition, as shown in FIG. 10, inside the attachment connecting body 21 in which the release adjusting mechanism 20 is formed on each of the outer side surfaces of the left and right oblique side plates 9 at an appropriate position on the knob 15 or on the oblique side plate 9. Alternatively, the angle of the pair of opposing primary reflecting mirrors 8A and 8B may be changed by one-touch operation by one-touch operation by appropriately inserting the fixing screws 20 so that they can be screwed and fixed. Furthermore, the defocus angle fine-tuning operation and slide operation of the primary reflecting mirrors 8A and 8B and the sliding operation of the secondary reflecting mirror body 5 may be electrically driven by applying the autofocus control principle.

Furthermore, the four viewing windows for viewing the secondary reflecting mirror body 5 installed substantially in the center of the binocular distance region of the reflecting mirror housing 1 are separated by the peek windows corresponding to the binocular distance. A back cover 17 for viewing formed by opening the hole 16 is detachably attached. As a result, the viewing field of the viewing image is selected and the visibility is improved, and the reflected light from the primary reflecting mirrors 8A and 8B when viewing the left and right secondary reflecting mirrors 5A and 5B of the secondary reflecting mirror body 5 ( (Image) and unnecessary light in the structure of the reflector housing 1 can be blocked (see FIGS. 1 and 9). In addition, a cylindrical eye shield plate 18 is provided in the peep hole 16 of the ornamental back cover 17 so as to project inwardly or outwardly from the inner surface or the outer surface to block unnecessary light in the reflector housing 1. Therefore, it is possible to further improve the visual easiness.

Next, an example of use of the device of the present invention will be described. First, at the time of photographing, as shown in FIGS. 2 and 3, for example, the reflector housing 1 and the video recorder V such as a video camera are the same. It is set to the front and rear of the tripod mount 2 via the mounting member 3 for mounting so that the lens of the video recorder V can be viewed through the rectangular viewing window 4 of the reflector housing 1. At a proper position, the video recorder V is set to the photographing interval state, and the object is a target object to be photographed evenly by the respective secondary reflecting mirrors 5A and 5B in the secondary reflecting mirror body 5 in the same image. Adjust it so it is captured. That is, as shown in FIGS. 4 to 8, by pressing the supporting screws 10 on the oblique side plates 9 on the left and right sides, the left primary reflecting mirror 8A, the secondary reflecting mirror 5A and the right primary reflecting mirror which are paired in the front and rear direction. 8B and the secondary reflecting mirror 5A, respectively, the angles of the left and right primary reflecting mirrors 8A and 8B with respect to the subject on at least one side are expanded or reduced in the left and right directions with respect to the secondary reflecting mirrors 5A and 5B. Adjust it by tilting it so that it is relatively variable. Further, by sliding the knob 15 along the slot 12, the secondary reflecting mirror body 5 is moved forward and backward, and the secondary reflecting mirrors 5A and 5B are moved forward and backward relative to the primary reflecting mirrors 8A and 8B. By making parallel movements, the viewing width (convergence) is secured and the eye-gaze effect is brought out to shoot a movie in one frame where two-image parallax occurs.

In addition, when a target object is misaligned between two images in the finder when the image is recorded by the video recorder V, or when the image is shifted to a near view or a distant view, the left and right primary reflecting mirrors 8A , 8B and the respective secondary reflecting mirrors 5A, 5B in the secondary reflecting mirror body 5 are moved relative to each other to adjust the balance of vertical, horizontal, and horizontal so that the left and right screens are desired images. To do. At this time, the incident angle of each of the left and right primary reflecting mirrors 8A and 8B may be swiftly and smoothly adjusted by the release adjusting mechanism 20 to correctly adjust the screen. In such a case, it goes without saying that each mechanism of the video recorder V, such as color adjustment, zooming, W balance, shutter speed, focus adjustment mechanism, etc., normally operates the normal functions of the video recorder V. That is.

When the recorded video image is to be played back and viewed, for example, it is set on the tripod mount 2 via the mounting member 3 of the reflector housing 1 and the screen of the display (for example, 14 inches) in a reproducing device such as a television is set. TV or 29-inch TV screen), or the viewer himself holds the reflector housing 1 in front of his face, and through the peephole 4 or the peephole 16 of the award back cover 17, see the same screen of the display. Two images with binocular parallax reproduced on the left and right are viewed at the same time.

At this time, by sliding the secondary reflecting mirror body 5 installed substantially in the center within the binocular distance range by the back and forth movement adjusting knob 6, the secondary reflecting mirror 5 in the secondary reflecting mirror body 5 is moved. The field of view is changed so that unnecessary parts inside the structure of the reflector housing 1 are not reflected in the images viewed by A and 5B. Then, by directly attaching the back cover 17 for viewing, which is provided with the viewing holes 16, to the viewing window 4 corresponding to the binocular distance, and indirectly viewing it, the primary screw 8A is supported by the support screw 10. Adjust 8B in the plus or minus direction from 90 degrees. Next, when the reflector housing 1 is set in front of the viewer, the two images are fused and integrated for stereoscopic viewing by looking through the viewing hole 16.

When stereoscopically viewing the image of the video recorder V in real time, two reflecting mirror casings 1 may be used. In this case, one of them is used for photographing and the other one is used. Since it is used at the same time as the one for appraisal, it is possible to see the image of a remote place at the same time as a stereoscopic image on a monitor.

[Effect of device]

 The present invention is configured as described above, and for this reason, stereoscopic video recording can be easily performed at low cost mainly by using a video recorder V such as a video camera that is extremely popular. Among them, in particular, it is possible to provide a stereoscopic viewing method capable of easily performing stereoscopic viewing and listening during playback after shooting a video image. Moreover, the number of parts is extremely small, the structure is simple, there is little risk of failure, and the structure is lightweight, small and portable, and therefore extremely easy to handle. Furthermore, not only stereoscopic moving image recording by a video camera but also two images with different binocular parallax can be recorded in the same screen, and thus stereoscopic recording by a still image camera is of course possible.

That is, in the present invention, this is the left and right primary reflecting mirrors 8A and 8B for reflecting the incident subject image, and the secondary reflecting object for the primary subject image reflected by the primary reflecting mirrors 8A and 8B. The left and right secondary reflecting mirrors 5A and 5B, which are reflected again as images, are arranged in front and back in a state of facing each other, and the front and rear reflecting mirrors 8A and 5A or 8B and 5B are respectively obtained. A single subject image is formed as two left and right different images with binocular parallax, and two left and right different images with this parallax are simultaneously shot and recorded on the same screen. This is because it is possible to do this. Also, in order to merge the two images on the left and right that differ in parallax when the left and right secondary subject images that have already been shot are reproduced on the same screen, the reflections that face each other before and after the above are combined. Mirror 8 This is because the left and right sides of A, 5A and 8B, 5B are divided into two different images for the left and right sides which generate the parallax required for stereoscopic vision, so that they can be viewed with both eyes.

Further, the left and right primary reflecting mirrors 8A and 8B are arranged on the inner side surfaces of the left and right oblique side plates 9, respectively, and the primary and secondary primary reflecting mirrors 8A and 8B are opposed to each other. The left and right secondary reflecting mirrors 5A and 5B arranged in front of the reflecting mirrors 8A and 8B are arranged, and the secondary reflecting mirrors are arranged in the reflecting mirror housing 1 in front of the viewing window 4. Since it is provided with the reflecting mirror body 5, it is possible to significantly increase the total degree of uplift, and it is possible to freely expand the range of the stereoscopic field of view. In particular, even if the viewing window 4 of the reflector housing 1 is within the binocular distance range, the space between the left and right primary reflecting mirrors 8A, 8B provided on the inner surface of the oblique side plate 9 of the reflector housing 1 is small. Since it is larger than the binocular distance range, that is, larger than the binocular distance, the stereoscopic field of view is increased when a subject image is incident on these.

In the bilaterally symmetric primary reflecting mirrors 8A and 8B, at least one of the left and right sides can appropriately change the reflection angle with respect to the secondary reflecting mirrors 5A and 5B facing each other. The secondary reflecting mirrors 5A and 5B can be slid back and forth, so that the same vergence as the binocular vision function can be secured, and the eye-gaze effect can be efficiently performed. The stereoscopic effect can be fully exerted, and at the same time, the fineness of the image can be extracted very effectively.

Since the back cover 17 for viewing, which is provided with the peephole 16 corresponding to the binocular distance, is detachably attached to the reflector housing 1, the secondary reflecting mirror installed in the approximate center of the binocular distance range. When the left and right secondary reflecting mirrors 5A and 5B in the body 5 are viewed with the left and right eyes, the image reflected light from the primary reflecting mirrors 8A and 8B and unnecessary light inside the structure of the reflecting mirror housing 1 can be blocked, which is suitable. An accurate field of view can be configured for easy viewing.

Further, with the devised device, traffic and people are monitored, nature / environment / animals etc. are monitored, sea / water level etc., seabed exploration, volcano monitoring, work robot monitoring, human face detection. Records of figures, records of animals and plants, records of sports, records of land and buildings, monitoring of work sites, use as leisure and playground equipment displays, moon maps, globe maps, mountain veins, model river and river images It can be used for a wide range of purposes, such as digitization, recording of sculptures, antique art, pottery, various three-dimensional images, three-dimensional recording of puppet plays and plays, three-dimensional recording of various images in a general household, and so on.
