As shown in fig. 3 and 4, the design of the cylindrical lens of the naked-eye 3D membrane has a light splitting function in both vertical and horizontal directions, depending on the angle between the cylindrical lens and the handheld deviceBut if the angle is not proper, the image has black-and-white stripes or rainbow stripes. As shown in fig. 5, when 4 sub-pixel units are arranged under one lenticular lens, and the width-to-length ratio of the sub-pixels is 1: 3; when in useThe view point corresponding lenticulation is a fixed position and has no offset periodic arrangement, so that the same view point can be in the same position after passing through the lenticule, the inclined design can not interfere with other view points, but black-white stripes or rainbow stripes can be generated.
Disclosure of Invention
The invention aims to solve the problem that a user cannot vertically and transversely see a better 3D display effect in naked eye 3D display of a handheld device at present, and provides a naked eye three-dimensional image device which comprises a 3D video file processing module, a naked eye 3D membrane and a 3D display module, wherein the arrangement mode of 3D video files is adjusted, and an included angle between a cylindrical lens of the naked eye 3D membrane and the handheld device is 23.96 degrees; the adjusted 3D video file is played on the handheld device provided with the naked eye 3D diaphragm, so that a user can have a better 3D display effect when looking vertically and looking horizontally.
In order to achieve the above object, the present invention provides a naked eye stereoscopic image apparatus, comprising: the device comprises a handheld device, a naked eye 3D membrane and a 3D video file processing module;
the handheld device is used for playing the 3D video file processed by the 3D video file processing module;
the naked eye 3D diaphragm is used for being installed on the handheld device, so that a 3D video file played by the handheld device has a 3D effect; the naked eye 3D membrane comprises a cylindrical lens grating group; the cylindrical lens grating group consists of a plurality of cylindrical lens gratings;
the 3D video file processing module is used for processing the 3D video file as follows: the lenticular group of the naked eye 3D membrane is shifted in the x and y directions according to the following period relative to the arrangement mode of the sub-pixels of the display screen of the handheld device: when the shift amount in the y direction is 1 pixel, the change period of the shift amount in the x direction is 1/3, 2/3, and 1/3 sub-pixels. The naked eye three-dimensional image device enables a user to have a good 3D display effect no matter the user looks vertically or horizontally.
In the above technical solution, the number of the sub-pixels covered by the lenticular lens grating is greater than or equal to 3.
In the above technical scheme, when the lenticular lens grating covers 4 sub-pixels and the width-to-length ratio of the sub-pixels is 1:3, the angle between the lenticular lens grating of the naked eye 3D film and the display screen of the handheld device isHas a value range of [23.93 degrees, 23.99 degrees ]]. The naked eye 3D film does not cause the picture to generate black and white stripes or rainbow stripes; but also maintains a good 2D resolution.
Further, preferably, the
The invention has the advantages that: when the naked eye three-dimensional image device is used, when a 3D image processed by the 3D video file processing module is played on a handheld device provided with the naked eye 3D membrane, a user has a good 3D display effect no matter in vertical view or in horizontal view, and black and white stripes or rainbow stripes cannot be generated; but also maintains a good 2D resolution.
