Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A viewing pattern for windowing type, relates to the shooting of stereopsis and watches.

The eyes that Figure 1 shows that simulation people are watched the visual angle of same scenery." left side " in Fig. 2, " right side " represents that respectively scenery passes through people's the eyes imaging on retina respectively.Owing to there being certain distance between eyes, can there is certain angle difference observing during same object, and the main source of such difference to be people produce stereoscopic vision.

The image that obtains similar Fig. 2 has two schemes: perspective transformations camera lens and software are auxiliary.

The first, perspective transformations camera lens:

As Fig. 3 and Fig. 4, before the camera lens of the mancarried electronic aid that can take, add and join an optical system, angle between the hypotenuse of the girdle prisms such as two right angles is 90 degree, hypotenuse overlapping position is just on the axis of former camera lens, on the both sides of two prisms, there are two and connected the rotary level crossing of fixed axis, angle by two level crossings of adjusting knob adjustment can be taken the image of different distance, thereby make single camera lens take similar Fig. 2 image, because the light of the right and left has certain differential seat angle, can adjust to the eyes of human eye between the identical angle of parallax, thereby realize with one group of parallax stereopsis of a lens shooting (imitating the vision deviation angle of eyes).Can on adjusting knob, mark out for the reference angle of different shooting distances and take to facilitate to adjust simultaneously.This mode can realize the shooting of photo and dynamic image.And plane reflection structure can not introduced new aberration, thereby and every one side all passed through two secondary reflections and avoided mirror image.

Meanwhile, in order to adapt to more various shooting demand, can before the camera lens of portable electronics capture apparatus, add that different additional transformation camera lenses is to change shooting focal length and visual field.

This optical system, the middle girdle prism that waits can be replaced with level crossing.

In the time of with prism, there is total reflection in light on right-angle side face.The imaging effect of prism can be better.

The second, software are assisted:

Along with the development of mobile device, its application software is also corresponding relates to various fields.Acquisition mode for Fig. 2 image is also convenient, and the image that can utilize capture apparatus to take respectively two in the position with certain distance and angle difference is realized.Then by application software, two photos are presented on display device by the mode of Fig. 2.But such position and angle are difficult to determine, the error of angle and distance can cause relief loss or image entanglement.

For this, the design discloses a kind of sharp support unit that gathers in this way image of being convenient to.As Fig. 5, follow shot equipment is fixed on slide block, and slider bottom is cylinder, cylinder can rotate, and cylinder can make more stable the fixing in orbit of slide block, is rectangular shaft on cylinder, it connects capture apparatus, and the side plane of rectangular shaft is for establishing shot angle.At the two ends of guide rail, have two blocks, it can, along rail moving fixing, can rotate in fixed position simultaneously, and top is adjusting knob, and below is rectangular block, thereby it is for the rectangular surfaces fixed angle of the slide block of fitting, as Fig. 8.When needs are taken, reference man's eyes distance, viewing distance and viewing angle, (eyes of being for example grown up are apart from can be with reference to 65mm in place by fixing two blocks, can need to regulate according to photographer self), as Fig. 6, rotary block to suitable angle (be similar to Fig. 1, can be marked on knob convenient adjustment with reference to angle) with the shooting for different distance scenery.Then moving slider, when the top block of slide block, the rectangular surfaces of the rectangular surfaces laminating block of slide block, slide block is rotated, as Fig. 7, thereby make capture apparatus turn over certain angle, when mobile device being moved to the same principle of opposite side after the image of having taken a side, take another.Thereby can realize the collection of the image to Fig. 2.

In the moving process of slide block, often can produce because rock skew, Fig. 9 and Figure 10 provide two kinds to make slide block when a photo moves to opposite side, keep uniform and stable method having clapped.Wherein slider bottom is all fixed on movably on gear bar.Wherein, as Fig. 9, first capture apparatus is pulled to right side, Compress Spring is blocked by card article simultaneously, taken after right photograph, press the button the elastic force of retracting spring, train of reduction gears is made capture apparatus move to uniformly opposite side with certain resistance, thereby takes.Also the mode that can use Figure 10, connects gear by stepping motor simultaneously, and stepping motor is output speed and the rotation number of turns evenly, and control button can be controlled its rotating, thereby can carry out the shooting of two positions by driven gear follow shot equipment.Fixed handle as shown in Figure 5 also can be replaced by other fastenings such as tripod.

For two kinds of image collection modes, be summarized as follows:

Mode (1) advantage: can take dynamic image;

Mode (1) shortcoming: introduce new optical device overall volume and increase, because transducer (COMS or the CCD) size that gathers image does not become, amount of images is double, thereby makes image resolution by half simultaneously;

Mode (2) advantage: image resolution is constant, more the property taken;

Mode (2) shortcoming: be difficult for taking, maybe will introduce auxiliary capture apparatus, cannot take dynamic image.

What below relate to is that the split screen image collecting is become to stereoscopic vision:

First need by display device profit by some way (film source or the software processing of taking as input stereoscope) be laterally divided into two parts, A as shown in figure 11, B, then by the image that is similar to Fig. 2 collecting is divided into two part A by display device, B shows, this two group image obtains according to the parallax of eyes when gathering, and just adapts to binocular stereo vision.

Facilities for observation is by a, and b and support form, as Figure 11 and Figure 12, and a, b is convex lens, AB plane is positioned at one times of focal length of lens ab, as Figure 13.Via ab, image near the distance of distinct vision (A ' B ' apart from EYES photopic vision scope) of human eye.It can reduce the simple eye angle of visual field, makes left eye only see A by a, and right eye is only seen B by b, thus the stereoscopic vision of realization.And, a, b has amplification effect, can increase visual magnification (ratio of the subtended angle of AB to eyes while the subtended angle A ' B ' of eyes being observed to image planes with bore hole by equipment after image) and make people have the more visual experience of shock.

The portable electronic equipment of taking that the technical program utilization is more and more advanced, makes three-dimensional experience more convenient, and has overcome stereoscopic viewing apparatus luminance shortage in the past, the problems such as colour cast.Increase visual magnification simultaneously, made viewing person have better visual experience.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
