Portable device with 3D (three-dimension) picture taking and 3D video displaying functions

Abstract

The invention discloses a portable device with 3D(three-dimension) picture taking and 3D video displaying functions. The portable device comprises a display panel, a backlight unit, a watch area separation unit, a polarizer, a polarization switch, a double-deflector and two cameras. The backlight unit provides a backlight source for the display panel; the watch area separation unit is used for separating watch area of a right-eye image from a watch area of a left-eye image; the polarizer is used polarizing light output from the display panel to generate first polarized light; the polarization switch is used for converting the first polarized light into second polarized light, and the second polarized light polarizes in a direction different from that of the first polarized light; the double-deflector has the refractive index changes along with polarization of incident light; and the two cameras are used for taking pictures in real time to form 3D images reaching the left eye and the right eye of a person respectively. 3D shooting and play functions are applied to portable devices such as mobile phones, laptops and the like, and video watching experiences of the portable devices are enhanced for people.

Description

technical field [0001] The invention relates to the 3D field, in particular to a portable device equipped with 3D photographing and 3D video display. Background technique [0002] 3D display technology can be divided into two categories that require wearing 3D glasses and naked-eye display, and their working principles are the same. The principle of recognizing a stereoscopic image is generally based on the principle that humans perceive the depth of an object with a slight difference between objects seen by the right eye and the left eye. The key to 3D display technology is how to enter only one set of content in two sets of different images into the left or right eye of a person, so that the visual difference in the brain forms a three-dimensional feeling. The special glasses used in the past are The main tool used to solve this problem. [0003] There are mainly two kinds of glasses that need to be matched with the 3D display in the early application of film and televis...

Problems solved by technology

[0005] However, when watching naked-eye 3D display, the viewer needs to maintain a certain position with the display device to see the image with 3D effect (3D effect is greatly affected by the viewing angle)
