Abstract
The present invention provides a stereoscopic image display which controls display mode of the stereoscopic image display according to the entered image signal and displays both 2D images and stereoscopic images at high resolution with better viewing. The stereoscopic image display is constituted of a device for comparing the image signal entered into the stereoscopic image to determine to either 2D image signal or stereoscopic image signal and a combined use type stereoscopic image display of 2D images and stereoscopic images which can display 2D images and stereoscopic images at high resolution by controlling illumination pattern of the light source device for the stereoscopic image display to provide better viewing.
Claims20
A stereoscopic image display, characterized in that an entered image signal is compared for determining whether the image signal is either a 2D image signal or a stereoscopic image signal and then an image display mode is switched to either a 2D image display mode or a stereoscopic image display mode.
A stereoscopic image display, characterized in that luminance of the stereoscopic image display is controlled to make a same volume of light entering into the eyes of an observer in the 2D image display mode and the stereoscopic image display mode.
A stereoscopic image display, characterized in that a switch timing between a 2D display mode and a stereoscopic image display mode is controlled so as to be performed after a pair of the image signals for the left eye and the right eye of the stereoscopic image signal have been completed.
A stereoscopic image display, characterized in that a switching timing between a 2D display mode and a stereoscopic image display mode is controlled so as to be performed within a blanking interval of an image synchronization signal.
A stereoscopic image display without glasses in which an optical means using an independent light source and a single focal length lens for the left and right eyes sorts an image to the left eye and the right eye of the observer to display, the stereoscopic image display, characterized in that an image display mode is switched to a 2D image display mode or a stereoscopic image display mode by changing an illumination pattern of a light source of the stereoscopic image display.
