External device for providing stereo photographing and display

The invention relates to a smart phone accessory, in particular to an external device for providing stereo photographing and display.

The development of multimedia technology has evolved from sound and flat image to stereoscopic image. Because of its sense of presence, stereoscopic images can present a more realistic face-to-face feeling, and have great potential for development in communication and multimedia entertainment.

At present, to form a stereoscopic image, it is necessary to capture an image pair of different viewing angles of the object, and the method of capturing the image pair mainly uses two types of single lens and two lens.

The dual-lens shooting method is just like the conventional two-lens stereo camera. As shown in Figure 1, the two groups of mirrors 1 are horizontally positioned at the left and right ends according to the principle of viewing objects by both eyes. The images of the objects are synchronously captured by the two groups of mirrors 1. However, if the size and weight of the mirrors required for using such a shooting mode are twice as large, it is difficult to meet the demand in terms of cost and portability.

The method of capturing images by a single lens, as shown in Fig. 2, mainly uses one camera 2 to shoot the same target twice in a horizontal displacement manner. This shooting mode requires precise horizontal control to ensure image parallax error. Minimize to achieve an optimized stereo effect. Or, as shown in Figure 3, there is also a 4 in front of the lens 3. With the refraction of 稜鏡4, you can capture two parallaxes on the same photo with one shot. Image to form a stereo image.

However, most of the stereoscopic images are currently used in general cameras. At present, most of the camera systems equipped with smart phones are still flat images, and smart phones with stereo images are not quite rare, and the cost is quite high. Consumers' selectivity is not high, and most of them are non-mainstream models, resulting in low consumer willingness to buy.

Therefore, the main purpose of the present invention is to provide an external device for providing stereoscopic photographing and display and an image processing method thereof, which solves the disadvantage that a camera of a general smart phone cannot capture and display a stereoscopic image.

In order to achieve the above object, the present invention is an external device for providing stereoscopic photographing and display, which is used in conjunction with a smart phone having a display screen and a shooting lens, which comprises a housing, a cymbal, a a front cover and a grating, wherein the housing has an accommodating space for accommodating the smart phone, a display opening corresponding to the display screen and a camera hole corresponding to the shooting lens, and the cymbal is locked to the camera a hole, the front cover is fixed to the display opening, the grating is embedded in the front cover, and the grating is aligned with the display screen.

The step includes a photographing program, a storing program, an image combining program and a display program, wherein the photographing program obtains a stereoscopic image for capturing the photographing lens through the pupil, and the stereoscopic image includes different viewing angles. a left image and a right image, the stored program is configured to store the stereoscopic image, the image combination program is a differential display, the left image and the right image are a stereoscopic display image, and the display program is to display the stereoscopic display image. By allowing the viewer to view the stereoscopic display image through the raster in the state of naked viewing, the left and right eyes can receive different images and display the stereoscopic image.

Accordingly, the photographing lens of the present invention can obtain a stereoscopic image by the splitting of the pupil, and can be reconstructed into a stereoscopic image through the image combining program, so that the viewer can pass through the image. When the raster displays the stereoscopic display image, the left and right eyes can receive different images, and the stereoscopic image can be displayed, so that the smart phone with only the flat image capability can be upgraded to have the functions of stereoscopic photographing and display to meet the use. Demand.
