Abstract

Principle of the stereo digital camera is as follows. The digital camera comprises two lenses at left and right sides respectively. Optimal viewpoint and visual angle can be selected. Adjusting visual angles of left and right lenses obtains images of object. Passing through relevant optical elements, the said images are mapped to image sensing chip. There are two different shutters corresponding to left and right lenses. Times for opening two shutters are different little bit. Thus, times of mapping image to sensing chip are also different. Images obtained are sent to computer for further processing. Images taken by left and right lenses are displayed on screen in turn. People wearing special 3D eyeglass is able to view image in real 3D effect.

Accompanying drawing 2 is position views of a kind of stereo digital camera of proposing of the present invention.

Accompanying drawing 3 is internal structure schematic diagrames of a kind of stereo digital camera of proposing of the present invention.

Embodiment

Below in conjunction with drawings and Examples operation principle of the present invention is described.

Basic structure of the present invention mainly is made up of stereo digital camera body (1), right lens assembly (2), left lens assembly (3), right shutter (4), left shutter (5), right reflector (6), left reflector (7), combined reflector (8) and image sensor chip (9).

Here the simple explanation basic principle of three-dimensional imaging once, people's eyes are when watching attentively object, because the distance between left eye and the pupil of right eye, be approximately 5cm, left eye and right eye will produce the image of the identical viewpoint of different visual angles to an object (same viewpoint in other words conj.or perhaps), these two different visual image signals, the acceptance of process brain and processing have just formed the stereoscopic visual effect of a three-dimensional, just we the image of the actual object of seeing, so, form the effect of the image of a solid, will allow two eyes receive the image of the identical viewpoint of different visual angles of object simultaneously.The related basic principle of this invention also is like this, the camera lens of digital camera is that two camera lenses are formed, be exactly right lens assembly (2) and left lens assembly (3), two eyes that are equivalent to the people, two partly are approximately 5cm apart between the center, suitable with the distance between people's the pupil, the people is when seeing the object of different distance, eyes can be done automatic adjustment, make sight be focused at the centre of object, form a center viewpoint, when infinity, two sight is promptly near two parallel lines states, and under very near situation, will be converted into a mid point, such as the line etc. of under very near situation, threading a needle, the viewpoint of two eyes can be focused at very near a bit, so the angle between two eyes is constantly along with the distance between watching attentively object and the people changes, this fundamemtal phenomena as shown in Figure 2, in the present invention, be provided with about two camera lenses just in order to simulate this principle.

In accompanying drawing 3, (1) is stereo digital camera body involved in the present invention, have on the stereo digital camera body (1) side by side about two camera lenses, wherein (2) are right lens assembly, (3) be left lens assembly, right lens assembly (2) is arranged with title with left lens assembly (3), and can carry out the adjusting of angle, so that take far and near different object and object, with right lens assembly (2), the position, inboard (or rear side) of left side lens assembly (3), at image sensor chip (9) before, the shutter corresponding with camera lens arranged: right shutter (4), left side shutter (5), they lay respectively at any position between right lens assembly (2) and left lens assembly (3) inboard and the image sensor chip (9), it is just passable promptly can to play the effect that stops light, in right lens assembly (2), the inboard of left side lens assembly (3) also has right reflector (6) respectively, left side reflector (7), in right lens assembly (2), also has combined reflector (8) between the left side lens assembly (3), when right shutter (4), when left side shutter (5) all is in the position of unlatching, the outside image light that will take passed through right camera lens (2) respectively, left side camera lens (3), can enter reflector (6), reflector (7), again by reflector (6), reflector (7) reflexes to combined reflector (8) with light, reflector (8) is made up of the reflecting prism of different angles, light from different directions can be reflexed to same target, like this, adjust mutual position and relation, just can image information be reflexed to image sensor chip (9) by combined reflector (8), so just can obtain to come from respectively left camera lens (2) at the active position of image sensor chip (9), the visual signal of right camera lens (3) diverse location just is equivalent to people's left eye and the signal that right eye is seen respectively.In practical structure and device, right shutter (4), left side shutter (5) is controlled by a shutter release, promptly just can finish the unlatching and the closure of two shutters by operator's once-through operation, but right shutter (4) is not to move at one time with left shutter (5), but the order of a priority is arranged, after pressing shutter release as the operator, left side shutter (4) is opened earlier and closed action, image sensor chip (9) obtains the image information in left side earlier, be sent to memory device earlier, after the process certain hour, for example 1/tens seconds one, now carry out the unlatching and the closed action of right shutter (5), obtain the image information on right side so again, image information with this side is sent to memory device again, because right shutter (4), left side shutter (5) is very short at interval, have only 1/tens seconds time words interior and that open respectively, disregard the significant response time of image sensor chip (9) and the words of recovery time, so just can be under the situation of an image sensor chip (9), write down right lens assembly (2) respectively, the different image information in lens assembly (3) both sides, a left side, a left side that just is equivalent to the people respectively, right two information that eyes are seen, computer or the out of Memory terminal that the information that obtained is transmitted again, through special disposal, just can reproduce lively three-dimensional image information.

Above-mentioned method can make ordinary consumer easily obtain and watch three-dimensional image true to nature, and equipment is simple, and is easy to operate, and stereoeffect is strong.
