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, when observing same object, can there is certain angle difference, 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 stationary shaft, 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 identical angle of parallax between the eyes with human eye, 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, one side thereby and every two secondary reflections that all passed through 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 support unit that profit gathers image in this way of being convenient to.As Fig. 5, follow shot equipment is fixed on slide block, and slider bottom is right cylinder, right cylinder can rotate, and right cylinder can make more stable the fixing in orbit of slide block, is rectangular shaft on right 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 rotate in fixed position along rail moving fixing 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, by two blocks, fixing in place (eyes of being for example grown up are apart from can be with reference to 65mm, 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 of slide block laminating block, slide block is rotated, as Fig. 7, thereby make capture apparatus turn over certain angle, after the image of having taken a side, mobile device can be moved to opposite side and take another by same principle.Thereby can realize the collection to the image of 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 can use the mode of Figure 10, by stepper motor, connect gear, stepper motor is output speed and the rotation number of turns evenly simultaneously, and control knob 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, do not become simultaneously owing to gathering sensor (COMS or the CCD) size of image, amount of images is double, thereby makes image resolution by half;

Mode (2) advantage: image resolution is constant, more portable;

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 display device profit (as inputted film source or the software of stereoscope shooting, to process) and be laterally divided into two parts by some way, 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 simple eye field angle, 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 AB to the subtended angle of 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 domain of the present utility model.
