発明の名称 (英語) IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD
発明の概要(英語) This image display device displays a stereoscopic image by a parallax barrier method, and is provided with: a plurality of display elements which are placed on a transmission type image display surface; a plurality of illumination placement control elements which variably control the placement of illumination light to be applied to the image display surface with respect to the image display surface and are placed on an illumination placement surface; and a control unit which controls the display elements, and controls the illumination placement control elements. The control unit is provided with a positional information acquisition unit which acquires positional information indicating an observer distance, a number-of-partitions calculation unit which calculates the number of partitions of each of a left image region and a right image region of the image display surface on the basis of the observer distance, an image display surface control unit which changes the number of partitions, and an illumination placement surface control unit which changes the respective placements of a barrier region and a slit region of the illumination placement surface on the basis of the number of partitions while keeping the width of the slit region at a width before the change of the number of partitions.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, a stereoscopic image without spectacles the research and development for the image display apparatus has been performed. Without the use of the stereoscopic image glasses to the image display device, for example, a time division of the parallax barrier autostereoscopic image display device (Patent Document 1) are known. Patent Document 1 of the autostereoscopic image display apparatus, the predetermined viewing direction of an observer who observes the right and left eyes, the stereoscopic display image 4 a plurality of periodic time series of a predetermined order are presented sequentially.
