Problems solved by technology

[0005] However, in practice, using two lens systems can cause more problems than using one lens system
[0006] First, if figure 1 As shown, when the two sets of lens systems 100 each consist of a lens 120 and a main body 110, it is difficult to maintain a distance equal to that of the eye point (eyespot) of a person.
[0007] Second, the two sets of lens systems 100 are difficult to synthesize using circuits
[0008] Third, in terms of cost, the use of two sets of lens systems 100 causes an increase in cost
In addition, it is difficult to uniformly operate the zoom lens and the focus lens
In addition, it is not easy to attach devices such as motors
[0009] Fourth, when shooting the object 140 in extreme close-up, the angle adjustment cannot be accurately realized with two sets of lens systems 100
In addition, since motors and devices (not shown) must be additionally attached, the size of the lens system becomes large
[0010] Fifth, keystone distortion occurs when the lens system is tilted toward the center to capture images of nearby objects
However, 100% usage is still not possible

no. 1 approach

[0087] Figure 7 The galvanometer provided in place of the rotating disk of the light transmissor / reflector according to the first embodiment of the present invention is shown. Refer to Figure 7 , The two front lenses 410 on the left and right sides maintain a binocular distance of 65 mm and are arranged in the front, so that the image is formed in the space behind the front lens 410. The first relay lens 420 is used to convert the image into parallel light. At the same time, total reflection mirrors 431-1 and 431-2 are used to synthesize images by galvanometer 433, in which two mirrors 433-1 and 433-2 are joined at 50°. Therefore, an image is formed on the CCD 480 via the second relay lens 460.

[0088] Specifically, for the light reflection operation, in the galvanometer 433 configured so that the mirrors 433-1 and 433-2 are formed on both sides at 50°, the light initially incident from the left side is passed by the total reflection mirror 431- 1 reflects and thus refracts 90°...

[0092] Figure 8 The galvanometer provided in place of the rotating disk 432 of the light transmissor / reflector 430 according to the second embodiment of the present invention is illustrated. Refer to Figure 8 , The two front lenses 410 maintain a binocular distance of 65 mm, and light is incident through the two front lenses 410 to form an image in the space behind the front lens 410. The first relay lens 420 is used to transform the image into parallel light. At the same time, total reflection mirrors 431-1 and 431-2 are used, thereby synthesizing images by the galvanometer 434 to which the reflection mirror 434-1 is attached. Therefore, the image is formed on the CCD via the second relay lens 460.

[0093] Specifically, for the light reflection operation of the galvanometer 434 constituted by the reflecting mirror 434-1, the light initially incident from the left is reflected by the total reflection mirror 431-1, thereby being deflected by 90° to the right. In this case, if t...

[0098] FIG. 9 illustrates a galvanometer provided in place of the rotating disk 432 of the light transmissor / reflector 430 according to the third embodiment of the present invention. 9, the two front lenses 410 maintain a binocular distance of 65 mm, and light is incident through the two front lenses 410 to form an image in the space behind the front lens 410. The first relay lens 420 is used to convert the image into parallel light. At the same time, total reflection mirrors 431-1 and 431-2 are used, thereby synthesizing images by the galvanometer 435 to which the reflection mirror 435-1 is attached. Therefore, the image is formed on the CCD via the second relay lens 460.

[0099] Specifically, for the light reflection operation of the galvanometer 435 constituted by the mirror 435-1, the light initially incident from the left is reflected by the total reflection mirror 431-1 and is thereby deflected to the right. In this case, if the galvanometer 435 rotates clockwise by an angl...

Abstract

Provided is a three-dimensional image capturing lens system having a structure in which left and right image sensing lenses are provided, and light is synthesized to form an image on a single CCD (charge-coupled device) in order to prevent loss of light intensity.

Description

Technical field [0001] The present invention relates to a three-dimensional camera lens system for shooting three-dimensional images, and more particularly to a three-dimensional camera lens system, which provides left and right image sensing lenses in its structure and combines light into a single CCD (charge coupled device). ) On the imaging, thereby preventing the loss of light intensity. Background technique [0002] Nowadays, with the recognition of the importance of three-dimensional images, various studies have been carried out not only in China but also in the world. [0003] However, despite the progress of various studies, these studies mainly focus on display. Therefore, there is almost no progress in the research of 3D image capturing equipment. [0004] Ironically, despite the recognition of the importance of three-dimensional images, people usually think that image shooting is performed simultaneously using two sets of lens systems. [0005] However, in practice, us...
