no. 1 approach

[0060] As described above, by providing pixels for displaying the image for the left eye and the image for the right eye in the two-dimensional display, and by using an optical unit such as a lenticular lens or a parallax barrier, the image for the left eye and the image for the right eye are distributed to the observer's A 3D display 20 that displays stereoscopic images for left and right eyes has been developed. In addition, in order to display images of objects as if they are suspended in the air, a three-dimensional aerial video display that combines a two-dimensional display and a real-mirror video imaging optical system and other spatial imaging devices has also been developed.

[0061] However, the conventional 3D video display device forms a floating image in the air by setting a 2D display corresponding to the viewpoint or moving the 2D display. Therefore, a two-dimensional display corresponding to the number of viewpoints or a driving unit for moving the two-dimensio...

Abstract

The invention relates to a stereoscopic display device and a parallax image correcting method. A combined structure of a 3D display and a spatial imaging device has the problem that an air suspension image occurs in a 3D front area and a 3D reverse area. The stereoscopic display device includes: a naked-eye stereoscopic display that projects respectively-different images into observer's left eye and right eye aligned in a first direction based on input images corresponding to two viewpoints; a flat-plate-shaped spatial imaging device that includes a plurality of optical reflection devices reflecting light transmitted from an object on a first reflection surface and a second reflection surface that are orthogonal to each other, the spatial imaging device emitting light that is emitted from the naked-eye stereoscopic display and is incident to an incident surface from an emission surface to an observer side; and an image processing unit that interchanges portions corresponding to reverse viewing areas in which depth parallax and popup parallax of the input images corresponding to the two viewpoints are reversed in a case where, in an image projecting one input image, an image projecting the other input image is mixed.

Description

technical field [0001] The present invention relates to a stereoscopic display device that generates a floating image in the air obtained by forming a three-dimensional image in the air, and a method for correcting parallax images in the stereoscopic display device. Background technique [0002] As a method for making an observer recognize a stereoscopic image, generally, a stereoscopic image display method based on binocular parallax utilizing a positional difference between the left eye and the right eye is used. This method is an application of the principle that the left eye and the right eye visually recognize different two-dimensional images, and the stereogram of the three-dimensional stereoscopic image is recognized in the brain based on the difference between observation methods. As a method of displaying a stereoscopic image, there are a method using glasses and a naked-eye method without using glasses. As naked-eye methods, there are binocular methods, multi-eye ...
