Abstract

In the case of a four-eye type stereoscopic viewing system, four videos (dots) 'video {circle over (1, video {circle over (2, video {circle over (3, and video {circle over (4', composing each of minimum units of video group are repeatedly arranged in a horizontal direction of a screen, and the minimum units of video group are arranged so as to be shifted by one dot in the horizontal direction per row. Edges for defining the width of an aperture are obliquely formed in correspondence with the shift in the horizontal direction of the minimum units of video group, and the aperture is formed so as to extend across the respective minimum units of video group on the rows, the edges being straight.

Description

technical field

[0001] The present invention relates to an image display device for making observers have stereoscopic vision, or making multiple observers see different images. Background technique

[0002] Conventionally, as a method of realizing stereoscopic image display without wearing special glasses, there are well-known parallax barrier method or lenticular lens method, but these methods combine images for the right eye and The image for the left eye is alternately displayed on the screen in the form of vertical stripes, for example, and the displayed image is separated by a parallax barrier or a lenticular lens and introduced into the observer's right and left eyes for stereoscopic viewing.

[0003] image 3 It is an explanatory diagram illustrating the principle of a four-eye stereoscopic viewing system stereoscopic image display device. In the horizontal direction of the screen 11, images ①, image ②, image ③, and image ④ with binocular parallax are arranged at pr...
