Abstract
The present invention realizes stereoscopic television broadcasting which can reproduce a stereoscopic image best in state of stereoscopic viewing and a receiver for the stereoscopic television broadcasting. In stereoscopic television broadcasting, a reference size of a display of a receiver is determined, images for right and left are displayed on the display with a reference size in a superimposing manner, and transmission is performed such that a distance between the same corresponding points of an infinite subject image is reproduced and displayed to be equal to an interpupillary distance of a human.
Claims5
In a stereoscopic television broadcasting of a two eyes stereoscopic viewing system where two images for right and left photographed from two points separated right and left are viewed while separated for respective right and left eyes of a human, a stereoscopic television transmission system which is configured such that a display width size of a receiver is determined to be a constant reference size, screen width centers for the respective right and left eyes are displayed at the same, or one, position in a horizontal direction on one display in a superimposing manner, and a distance between the right and the left of the same corresponding points on an infinite subject image is reproduced to be a distance equal to an interpupillary distance of a human.
A stereoscopic television receiver of a two eyes stereoscopic viewing system where images for right and left are viewed while separated for respective right and left eyes of a human, wherein images for right and left are displayed at the same, or one, position on a display with a reference size in a superimposing manner and a distance between the right and the left of the same corresponding points on an infinite subject image is displayed to be equal to an interpupillary distance of a human.
A stereoscopic television receiver wherein a display with a width narrower than that of a display with a reference size is used, black non-display portions are provided on a right end portion of a display screen for left and a left end portion of a display screen for right, respectively, and displaying is performed such that widthwise centers of the display screens for right and left are displaced on the display in directions away from each other, so that a right viewing field and a left viewing field are caused to coincide with each other at a position far from a surface of the display and a distance between the right and the left of the same corresponding points on an infinite subject image is displayed to be equal to an interpupillary distance of a human.
A stereoscopic television receiver wherein a display with a width wider than that of a display with a reference size is used, black non-display portions are provided on a left end portion of a display screen for a right and left end portion of a display screen for right, respectively, and displaying is performed such that widthwise centers of the display screens for right and left are displaced on the display in directions in which the centers come close to each other and further in directions in which the centers switch positions with each other so that a right viewing field and a left viewing field are caused to coincide with each other at a position before the display and a distance between the right and the left of the same corresponding points on an infinite subject image is displayed to be equal to an interpupillary distance of a human.
