DESCRIPTION OF THE PREFERRED EMBODIMENTS A conventional mechanical 3D camera (MEC)
HANICAL 3D CAMERA) is designed to imitate the human eye, and there are two or more lenses with fixed parallel or angle, or one 3D lens because of the mechanical structure of film exposure. Lens to which the converter is connected, or each type of polarized lens (LENTICUL)
ARLENS, POLARIZING FILTER
DEVICE) to achieve the purpose of 3D photography. However, when the eyes of human beings see an object at a different distance, their eyes (the left eye 51 and the right eye 52) gaze at different angles, and the closer the object to be watched, the greater the angle. That is, the angle formed by the line of sight with the object and the eyes (physical light angle, OPTICAL ANGLE) increases (the light angle A1 is larger because the target 2 at the first position 41 in FIG. 4 is closer to both eyes). On the other hand, if the distance between the scenery and the object is long, the angle formed by it and both eyes will be small. Since the target at the second position 42 shown in FIG. 4 is far from both eyes, the light angle A2
Is smaller.

In order to improve the structure of a conventional mechanical 3D camera, an electronically controlled digital camera and a semiconductor CCD are used.
(CHARGED COUPLER DEVICE),
It also utilizes a memory device that replaces conventional film. Since the lens of a digital camera is not restricted by the exposure structure of a conventional camera (the lens and film are always fixed together and cannot be rotated or moved), it is only necessary to connect the lens to the digital camera body with an electronic circuit. Because it is good, the lens can rotate and move more freely. The 3D digital photographing apparatus of the present invention has a conventional digital camera as a main body, an independent first camera lens 11 and a second camera lens 12 arranged, and the first camera lens 11 and the second camera lens 12 are connected to each other. By rotating (manually or automatically) in a certain direction, the two lenses are adjusted to focus on the respective objects. It is the same as when the eyes of a person gaze at a scenery or an object, the eyes of the eyes match the scenery or an object. Other 3D
In order to enhance the effect, the first camera lens 11 and the second camera lens 12 are horizontally moved (the same principle that the distance between the eyes of each person is different). Increasing the stereoscopic distance increases the light angle formed by the lens with the scenery or the object, and increases the light angle, that is, the closer the scenery or the object, the higher the 3D effect.

The 3D digital photographing apparatus according to the present invention has a
At least two or more first camera lenses 11 and second camera lenses 12, which keep the interval at an appropriate distance to take a stereoscopic image of
Support the first camera lens 11 and the second camera lens 12,
A lens support mechanism for controlling and adjusting the stereoscopic distance and the focal direction between the first camera lens 11 and the second camera lens 12, and the stereoscopic camera using a different stereoscopic distance and a visual angle of a target (VISUAL ANGLE) using the lens support mechanism. Take an image. An angle is formed by at least two or more straight lines of the first camera lens 11, the second camera lens 12, and the target 2.

The partial lens support mechanism of the present invention includes a track 3 and a first camera lens 11 and a second camera lens 12 mounted on the track 3, and the first camera lens 11 and the second camera lens 12 3 to adjust the solid distance L between the first camera lens 11 and the second camera lens 12. Further, two or more first rotation axes 31 and second rotation axes 32 are used to focus the first camera lens 11 and the second camera lens 12 on the target 2, and the first rotation axis 31 and the second rotation axis 32 are used. A first rotating shaft 31 and a second rotating shaft 32 (see FIGS. 1 and 2) which can adjust the direction of the camera by controlling a motor or an electronic circuit to adjust the distance between the two. The camera of the present invention is a digital camera having at least two lenses, and the 3D digital photographing method of the present invention includes the following steps. (A) A 3D digital photographing apparatus according to claim 1 is prepared. (B) Adjust the solid distance L between the camera lenses. (C) Focus the camera lens on the target. (D) A three-dimensional image of the target is taken.

FIG. 3 is a flow sheet of a digital camera system used by the present invention. It can be seen from the figure that the captured stereoscopic image can be input to a television or computer.
The left and right images processed by the software can be viewed as stereoscopic images by the viewer on a screen or 3D glasses.

The advantages of the 3D digital photographing apparatus and its method according to the present invention are as follows: (1) Stereoscopic photography (STEORESCOPIC PHOT)
OGRAPHY) to enhance the three-dimensional effect by actively using the special effect expression. (2) Reduction of discomfort and unsuitability due to parallax. (3) Simple usage. (4) Reproduce the images seen by patients with various visual impairments and apply them to medical research. (5) The present invention relates to a conventional mechanical camera (MECHANIC).
Unlike AL CAMERA), it is very convenient because the two units are integrated. To obtain the same effect as the 3D shooting of the present invention with a conventional mechanical camera, two cameras of the same product and the same as the present invention Need a lens that can rotate
If it is made, the volume becomes large, it is inconvenient to carry, and the operation and assembly are complicated. (6) A stereoscopic image suitable for a human to see with both eyes (a small parallax and a high 3D effect) is projected compared to a conventional mechanical stereoscopic camera. That is, since the lens of the conventional mechanical stereoscopic camera is fixed, it cannot be rotated and moved, and the stereoscopic effect of the photographing is limited. (7) One of the features of the present invention is that it is easy to use and has good operability. Digital cameras use auto focus (AUTO
Using the function of FOCUS), control the electric circuit with a computer, automatically adjust according to the distance between the two lenses and the distance between the objects, obtain the best light angle and viewing angle, and 3D
Take a photo. With a conventional mechanical stereo camera or two cameras, a stereoscopic image is taken by rotating the lens in the same manner as in the present invention, but the photographing must rely on an experienced photographer. Cannot be spread to the masses. (8) The present invention adopts electronic digital camera design, product production, assembly and performance measurement can be fully automated assembly and computer-based automatic performance measurement. The present invention is simpler and saves manufacturing costs compared to the conventional manual production of mechanical stereoscopic camera assembly, adjustment, performance measurement and the like. (9) The application of 3D images in the future will achieve virtual reality by the effect of digitized stereoscopic images in accordance with advances in computer multimedia. Another feature of the present invention is that a synthesized stereoscopic image can be directly transmitted to a computer using a digital camera and a computer. This is impossible with a conventional mechanical stereoscopic camera, and it is impossible to input a photo to a computer for the first time after developing and then reading the photo with a scanner. Then, the two left and right photographs are combined by a computer to create a three-dimensional image. As described above, the production process is complicated and cumbersome, and the efficiency and practicality are far from being accepted by the public, and it goes without saying that it is not widely used. (10) Comparing the cost of the present invention with the cost of one digital camera having one general lens, the cost of the present invention is slightly higher than that of one digital camera. The invention is 3D
In addition to taking a picture, the switch of the electronic line of one lens is the same as the function of a general digital camera, so that one unit has multiple functions, at the same time, the utility of the present invention,
The advantages of convenience, ease of production, and savings in manufacturing costs will of course be more acceptable to consumers than conventional mechanical stereo cameras.
