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 A galvanometer provided instead of a rotating disk of a light transmitter / reflector according to a first embodiment of the invention is shown. refer to Figure 7, the two front lenses 410 located on the left and right sides maintain a binocular distance of 65mm and are arranged at the front so that images are formed in the space behind the front lenses 410 . The first relay lens 420 is used to convert the image into parallel light. Simultaneously, an image is synthesized through a galvanometer 433 using total reflection mirrors 431-1 and 431-2, in which two reflection 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 such that reflection mirrors 433-1 and 433-2 are formed on both sides at 50°, light initially incident from the left side is captured by the total reflection mirror 431- 1 is reflec...

The image is transformed into parallel light by the first relay lens 420 . Meanwhile, the total reflection mirrors 431-1 and 431-2 are used, whereby images are synthesized by the galvanometer 434 to which the reflection mirror 434-1 is attached. Therefore, an 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 reflection mirror 434-1, 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 ...

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 imaging lens system for shooting three-dimensional images, and more particularly to a three-dimensional imaging lens system in which left and right image sensing lenses are provided in its structure, and light is synthesized in a single CCD (charge coupled device ) to prevent loss of light intensity. Background technique [0002] Nowadays, with awareness of the importance of 3D images, various studies are being conducted not only domestically but also worldwide. [0003] However, although various studies have progressed, these studies have mainly focused on display. Therefore, research on three-dimensional image capturing devices has hardly progressed. [0004] Ironically, despite the perceived importance of 3D imaging, it is often assumed that imagery is captured simultaneously using two lens systems. [0005] However, in practice, using two lens systems creates more problems than using one lens ...
