Abstract

A method for displaying stereoscopic image, applied in a stereoscopic image device which includes a grating. First of all, the stereoscopic image device receives and stores a plurality of two-dimensional images of a scene with different perspectives. Then, the stereoscopic image device senses a rotation angle of the stereoscopic image device or a position of a user to output a sensing signal. After that, the stereoscopic image device outputs two of the two-dimensional images which are stored according to the sensing signal. Then, the stereoscopic image device uses the grating to output a stereoscopic image with the two of the two-dimensional images which are output by the stereoscopic image device. Therefore, since the stereoscopic image device can display multi-view stereoscopic images without reducing resolution, the problem that the user's left eye sees the right eye image and right eye sees the left eye image (Pseudo Stereoscopic 3D) can not be generated.

Description

Stereoscopic image display method and stereoscopic image display device

The present invention relates to an image display method and an image display device, and more particularly to a stereoscopic image display method and a stereoscopic image display device.

At present, there are mainly two methods for displaying a stereoscopic image by a stereoscopic display device. One is that the viewer must wear the specially treated glasses to view the display device so that the left eye and the right eye receive different images, or the left eye and the right eye. The images alternately appear to produce a stereoscopic image. This method can be used to see stereoscopic images by the viewer wearing additional glasses, which is inconvenient to use.

The other is a naked-eye display device, which is a principle in which the display device uses a grating, so that the viewer can make the stereoscopic image different from the image seen by the left eye and the right eye without wearing any additional device. Used in print, baseball cards or partially naked-eye electronic stereo displays. When the viewer's left and right eyes are in two different visible areas, the viewer can view the stereoscopic image. However, a general handheld stereoscopic stereoscopic display device is often designed with dual viewing angles, and a multi-view stereoscopic image cannot be seen. In addition, when the user rotates the handheld stereoscopic display device or the relative position between the user and the handheld stereoscopic display device is different, the user sees the right eye image for the left eye and the left eye for the left eye. Eye image, and see the wrong stereo image.

The invention provides a stereoscopic image display method and a stereoscopic image display device, thereby solving Resolve the problems of the prior art.

The present invention provides a stereoscopic image display method suitable for a stereoscopic image display device including a grating and a sensor. The stereoscopic image display method includes the following steps: receiving and storing a plurality of two-dimensional images having different viewing angles of a scene; sensing a rotation angle of the stereoscopic image display device or a position of a user to output a sensing signal; The test signal outputs two different two-dimensional images in the stored two-dimensional image; and the two different two-dimensional images outputted by the grating are combined into one stereo image.

The present invention provides a stereoscopic image display device including a sensor, a processor, a display panel, and a grating. The sensor is configured to sense a rotation angle of a stereoscopic image display device or a position of a user to output a sensing signal. The processor is coupled to the sensor and configured to receive and store a plurality of two-dimensional images having different viewing angles of a scene, and output two different two-dimensional images of the stored two-dimensional images according to the sensing signals. The display panel is used to display two different two-dimensional images output by the processor. The grating is used to synthesize two different two-dimensional images output by the display panel into one stereo image.

The stereoscopic image display method according to the present invention is applicable to a stereoscopic image display device including a grating and a sensor. The stereoscopic image display method can display a multi-view stereoscopic image without reducing the resolution, and can cause the stereoscopic image display device to display a multi-view stereoscopic image according to the rotation angle of the stereoscopic image display device or the position of the user, so as to solve the conventional technology. There may be a problem in which the user's left eye sees the right eye image and the user's right eye sees the left eye image.
