Description

Multi-Frame Digital Stereoscopic Camera and Shooting Method {DIGITAL STEREOSCOPIC CAMERA OF MULTI FRAME TYPE AND PHOTOGRAPHING METHOD THEREOF}

The present invention relates to a multi-frame type digital stereoscopic camera and a photographing method thereof, and more particularly, to an image sensor module including an image sensor unit for simultaneously recognizing left and right images obtained from an optical unit and adjusting the position of the image sensor unit. A multi-frame type digital stereoscopic camera having a device and a photographing method thereof.

Advanced countries, including Korea, are actively conducting R & D in the field of stereoscopic imaging, which is emerging as the next generation media.

However, research on the field of stereoscopic imaging equipment has been virtually neglected due to economical logic because it is possible to acquire stereoscopic images by attaching two lenses to two cameras and simultaneously photographing them. Can see

On the other hand, when shooting a three-dimensional image using the two conventional cameras and the conventional lens is not only close to the near and impossible to see a long time because of poor image quality, it is difficult to control the two cameras and the lens at the same time It is not easy, and the keystone is generated, and the horizontality of the left and right images does not match, causing a headache, and additional additional equipment is essential to provide high quality images. There were various problems.

Therefore, there has been a technique of installing an adapter optical system in front of a camera lens as a conventional technique for solving the above problems caused when taking a stereoscopic image using two cameras and lenses as described above.

However, the technique of installing the adapter optical system in front of the camera lens has a problem that only a low-level stereoscopic image can be obtained due to the optical path loss because a beam splitter is used to combine the left and right optical paths of the lens system into one optical path.

Korean Patent No. 10-0786677 is a conventional technology filed by the present applicant in order to solve the above problems, and maintains the binocular spacing 65, the distance between the left and right eyes of the person, to feel a perfect three-dimensional feeling left, Stereoscopic image using a lossless optical path combining device that combines the left and right images obtained from the stereo zoom lens system designed with two right optical paths into one optical path and transmits them to one camera CCD so that there is no light loss in a left and right intersection. By providing a stereo zoom lens system for shooting, it is a technology to realize a three-dimensional image with a single camera without light loss.

As described above, the conventional technology of implementing a stereoscopic image using a single camera without optical loss solves a fundamental problem of optical loss when combining optical paths, which is the most important problem in the technique of acquiring a stereoscopic image using a single camera. The same problems were found.

First, since the left and right images are simultaneously taken by one camera, a time difference of 1/60 second appears between the shooting of the left image and the right image. That is, in the progressive camera shooting 60 frames per second and the interlaced camera photographed at 60 fields, the left and right images are captured at 60 frames at 30 frames per second at each intersection or 60 fields at 30 fields each. The left and right images are horizontally different from each other in proportion to the speed of movement in the fast-moving part, and when panning from left to right, distortion of the stereoscopic images comes from a 1/60 second time difference depending on the speed of panning. There is a problem that you can not feel the eye fatigue.

Second, due to the lossless optical path combiner, the left image is maintained in high quality, but the right image is deteriorated because the half moon reflection mirror reflecting the right image must be rotated at a right angle to the rotation axis. There is a problem. This is the best three-point tilt adjuster in the center of the rotating shaft using an optical measuring device when shooting, but the zero point changes even when the temperature and the external shock is weak, so it is proportional to the change and is focused on the right image reflected on the reflective mirror. This is because the bleeding phenomenon occurs like the picture was taken in the wrong state.

Third, the larger the size of the objective lens is, the better it is to design a high-performance zoom lens system in the optical design of the stereo zoom lens system, but it is virtually impossible to use an objective lens larger than 55Φ in order to maintain a 65 mm runaway interval. There was a fundamental problem in completing a high performance stereo zoom lens.

Therefore, not only the distortion of the stereoscopic image due to the cross-photographing of the left and right images and the resolution deterioration due to the external shocks can be prevented, but the obtained stereoscopic image can be realized in various resolutions as necessary and provide high quality digital stereoscopic images. There is an urgent need for realistic and highly available technologies.
