The stereoscope (10, 100) comprises lens height-adjusting parts (30) for holding a first lens part and a second lens part such that the vertical heights of a first lens and a second lens can be adjusted within the range from a first height to a second height while the first lens and the second lens are placed side to side so as to be parallel with a horizontal direction. Furthermore, the stereoscope can further comprise lens interval-adjusting parts (50, 150) capable of adjusting horizontal intervals between the center of the first lens and the center of the second lens within a predetermined range. The stereoscope can also be formed by comprising an eyeglass frame and eyeglass temples and allowing a horizontal diameter of a lens mounting part of the eyeglass frame to be larger than that of the lenses so as to adjust the horizontal intervals of the two lenses.

Description

Simple stereoscopic mirror that shows side-by-side images in stereoscopic images

The present invention relates to a stereoscope (stereoscope) used as a tool for viewing stereoscopic images, and more particularly, to a simple stereoscopic stereoscopic view of a side-by-side stereo image as a stereoscopic image. .

When a person observes an object with both eyes, the image of the same object viewed at a slightly different angle by the distance between the left eye and the right eye is formed in both retinas through the eyes, and then transferred to the brain. The human brain receives the two images and synthesizes them to recognize the perspective of three-dimensional space. Recently, as the attractiveness of 3D stereoscopic images is known, production and consumption of stereoscopic images is increasing. One of the conventional methods for viewing stereoscopic images is that the same object is represented by two images with a slight gaze deviation, similar to the principle that a person feels a three-dimensional effect with two eyes, so that a person can see one by one. That's how. In order to view stereo images taken by the side-by-side method as stereoscopic images, a stereoscopic mirror suitable for the stereoscopic image should be used.

Among various stereoscopic mirrors, a simple stereoscopic mirror is known that can be placed on a side-by-side image and a stereoscopic view of the image. 1 shows a representative example of a conventional pocket stereoscope 1. The pocket-shaped stereoscopic mirror 1 has two lenses 2 mounted in two lens holes provided spaced apart from the left and right by the lens mounting plate 3, and the length is provided at both left and right ends of the lens mounting plate 3, respectively. The same four legs (4) is installed to extend downward.

The structural feature of the pocket stereoscopic mirror 1 is a stereoscopic image, in which the separation distance between the object 5 to be viewed and the two lenses 2 is fixed so that the user cannot adjust it, and the distance between the two lenses 2 is also fixed. The user cannot adjust it. In general, the distance from the object 5 to the lens 2 is preferably about 50 to 100 [mm]. Since the visual characteristics (focal length) are different for each person, the optimum value of the separation distance may be different accordingly. If the separation distance is not adjustable, the object 5 may be viewed in a state in which the focal length is not adjusted. In addition, statistics show that the distance between two eyes of a person differs according to age, sex, race, and the like. The distance between eyes is 40 ~ 50mm until children become adults. The average distance between eyes of adult women is about 55mm and adult men is 65mm. Whites are 2 ~ 3mm narrower than black and yellow races. If the structure of the two lenses (2) can not be adjusted, there is a burden to make different kinds of products with different lens spacing. In addition, since the user usually does not know the distance between his eyes, it is inconvenient to try to wear various products directly and select a product that fits the distance between them.

On the other hand, in recent years, viewing photos and videos with a smart phone has become common. Photographs and video contents produced for viewing in 3D (3D) are also increasing. Rendering such photo or video content on a smartphone screen in the form of side by side stereo image, and viewing the rendered screen using a stereoscopic mirror, the photo or video can be viewed in three dimensions. In order to view such stereoscopic images, stereoscopic mirrors optimized for smart phones are required.

An object of the present invention is to provide a stereoscopic mirror configured to adjust the separation distance between the two lenses and the smartphone screen according to the focal length characteristics of the user.

Another object of the present invention is to provide a stereoscopic mirror configured to adjust the distance between two lenses to the distance between two eyes of a user.

Another object of the present invention is to provide a stereoscopic mirror that is optimized for stereoscopically viewing side by side stereoscopic images displayed on a screen of a smartphone.

And an interval adjusting means for varying at least one of heights (hereinafter, referred to as 'height of lenses on a screen'), to display an image reproduced in a side by side form on a screen of the portable video player. A stereoscopic mirror is provided so as to make a stereoscopic image through the first lens and the second lens.

According to one example, the gap adjusting means includes a lens height adjusting unit for holding the lens frame to adjust the 'height of the lens on the screen' within a range from the first height to the second height. The lens height adjusting unit includes: a first height adjusting bar extending a predetermined length vertically downward from one side edge of the lens frame; A second height adjustment bar extending a predetermined length vertically downward from the other edge of the lens frame; And a first guide part and a second guide part which are provided at predetermined distances from the left and right sides of the lens leg part and are respectively engaged with the first height adjusting bar and the second height adjusting bar to slide in a vertical direction. Include.

The lens height adjusting unit may move the 'height of the lenses on the screen' by 55 to 65 mm by sliding the first and second guide parts of the first height adjusting bar and the second height adjusting bar. It is desirable to be able to adjust to a desired value within the range.

The stereoscopic mirror, according to a preferred embodiment, may further include a support support member for supporting the lens leg to maintain the upright state in the vertical direction. Furthermore, the stereoscopic mirror may further include a pressing member for holding and holding the portable video reproducing apparatus mounted on the supporting member toward the supporting member.

According to another preferred embodiment, the stereoscopic mirror extends horizontally from the bottom of the rear surface of the lens leg to the plate member to the rear of the lens leg, then vertically bent downward to extend a predetermined length, and then horizontally extends to the front of the lens leg. Having a shape, when one corner portion of the portable video reproducing device is inserted between itself and the bottom of the lens leg portion, the portable video reproducing device is fitted to hold the screen parallel to the first lens and the second lens. It may further include a support member.

The gap adjusting means is configured to slide the first lens frame in a horizontal direction with respect to the first height adjustment bar and to slide the second lens frame in a horizontal direction with respect to the second height adjustment bar. It is preferable to include a lens spacing control unit to be coupled to allow the 'inter-lens spacing' to be adjusted within a predetermined range. In this case, the lens frame includes a first lens frame surrounding the first lens and a second lens frame surrounding the second lens and separated from the first lens frame.

The lens spacing adjusting unit may adjust a horizontal distance between the center of the first lens and the center of the second lens within a range of 40 to 70 mm.

According to another preferred embodiment, the three-dimensional mirror may further include a gripping portion connected to the end of the lens leg portion to hold the body of the portable video playback device to surround the body portion in two places.

According to another preferred embodiment, the gap adjusting means includes a lens gap adjusting unit for adjusting the horizontal gap between the center of the first lens and the center of the second lens within a predetermined range. In addition, the lens spacing adjusting part includes first and second lens fittings provided to be parallel to the lens frame, and first and second lens rims surrounding edge portions of the first and second lenses. The first and second lens fittings have a larger horizontal diameter than the first and second lens fittings, so that the first and second lens fittings are press-fitted to the first and second lens fittings. It can be moved in the horizontal direction by means of which the 'gap between the lens' can be adjusted.

In the lens gap adjusting unit, a plurality of engaging grooves are formed in a row in the horizontal direction on the inner upper and lower surfaces of the first and second lens fittings, and on the outer upper and lower surfaces of the first and second lens rims. A locking protrusion is provided, and the 'interval between lenses' is adjusted according to which locking groove of the plurality of locking grooves is caught.

The lens leg is preferably configured to be hinged at a point away from the lens frame at a predetermined distance orthogonal to reduce the volume by folding at the hinge.

By the structure capable of varying the vertical separation distance of the two lenses with respect to the three-dimensional image viewing object, the user can adjust the separation distance to match the focal length of their eyes. When the two lenses are separated by the optimum separation distance from the object, the object is seen most clearly. Therefore, the stereoscopic mirror of the present invention can adjust a customized focal length according to his or her eye characteristics to an optimum state regardless of which user uses it so that a clear stereoscopic image can be viewed.

As mentioned above, the distance between the two eyes is different for each person. The stereoscopic mirror proposed by the present invention can vary the horizontal separation distance between the two lenses, so any user can use the distance between the two lenses according to their own eye distance. You can adjust the interval. By adopting such a gap adjusting structure, the production cost can be reduced because it is not necessary to make a three-dimensional mirror having various lens gap sizes. Users can view stereoscopic images with the distance between the two lenses perfectly matched to their eye intervals, so there is no inconvenience in viewing, reducing eye fatigue, and high quality images.

In addition, the three-dimensional mirror of the present invention is optimally designed for a recent smart phone, it is convenient to enjoy the stereoscopic side-by-side stereo image with a smart phone.
