METHOD FOR SETTING STEREOSCOPIC IMAGE DATA AT A STEREOSCOPIC IMAGE DISPLAY SYSTEM
First Claim
1. A method for setting stereoscopic image data at a stereoscopic image display device, said method comprising:
- providing a light beam controller having a long axis tilted relative to a plurality of vertical lines at a predetermined tilted angle, wherein said light beam controller is configured to concentrate light beams emitted from a pixel matrix at a predetermined position, wherein said pixel matrix includes a plurality of sub-pixels disposed at intersections of horizontal lines and vertical lines;
setting stereoscopic image data at a home position of said pixel matrix in order to concentrate light at a first viewing position; and
setting stereoscopic image data at a different position that is shifted from said home position by a predetermined number of rows of said horizontal lines in a direction of said vertical lines corresponding to an up-down direction of a viewer in order to concentrate light at a second viewing position that said viewer has moved from said first viewing position in a left-right direction of said viewer.

Abstract
A method for moving viewing positions of a stereoscopic image display system is disclosed. Each cylindrical lens is tilted relative to vertical lines. A data stripe for left eye and a data stripe for right eye making up stereoscopic image data are alternately set to correspond to the cylindrical lenses. At a home position, a long axis of the cylindrical lens agrees with the center of each data stripe, thus concentrating light at a predetermined concentrating position. When setting stereoscopic image data at a different position of sub-pixels that is shifted vertically downward from the home position, the center of the data stripe is shifted relative to the long axis by 0.5 times the length of the sub-pixels horizontally to the left thus concentrating light at a concentrating position moved from the home position in the left-right direction.

9. A method for moving a viewing position of a stereoscopic image display device, said method comprising:
-
providing a light beam controller having a plurality of elements aligned in a horizontal direction, each of said plurality of elements includes a long axis that is tilted relative to a plurality of vertical lines at a predetermined tilted angle, wherein said light beam controller is configured to concentrate light beams emitted from a pixel matrix at a predetermined position, wherein said pixel matrix includes a plurality of sub-pixels disposed at intersections of horizontal lines and vertical lines; setting stereoscopic image data at a basic position of said pixel matrix; shifting a setting position of stereoscopic image data at said pixel matrix in accordance with a viewing position from a basic position by a predetermined number of rows in a direction of said vertical lines; and shifting a setting position of stereoscopic image data at said pixel matrix in accordance with a viewing position from said basic position by a predetermined number of columns in a direction of said horizontal lines. - View Dependent Claims (10, 11, 12, 13, 14)

15. A stereoscopic image display system comprising:
-
a light beam controller having a long axis that is tilted relative to a plurality of vertical lines at a predetermined tilted angle, wherein said light beam controller is configured to concentrate light beams emitted from a pixel matrix at a viewing position, wherein said pixel matrix includes a plurality of sub-pixels disposed at intersections of horizontal lines and vertical lines; a data conversion circuit for converting stereoscopic image data to be set at a home position of said pixel matrix into stereoscopic image data to be set at said pixel matrix at a position where said horizontal lines are shifted from said home position in a direction of said vertical lines corresponding to an up-down direction of a viewer by a predetermined number of rows; and a viewing position detection circuit that detects a viewing position of said viewer, wherein said data conversion circuit determines the number of rows of said horizontal lines for shifting and a direction for shifting in accordance with an output from said viewing position detection circuit. - View Dependent Claims (16, 17)
