Stereoscopic image display method, and stereoscopic image display apparatus using the method

A stereoscopic image display apparatus comprising:

• a display for sequentially forming a single stripe image obtained by arranging and synthesizing some of a plurality of stripe pixels which are obtained by dividing each of right- and left-eye parallax images supplied from a parallax image source having parallax image information, while performing a scanning operation;
• and
• a spatial light modulation element located on a front or rear side of said display, said spatial light modulation element sequentially forming a slit pattern consisting of a light- transmission portion and a light-shielding portion arranged at a predetermined pitch in synchronism with the scanning operation, and light transmitted through the stripe pixels, corresponding to right and left eyes of an observer, of the stripe image displayed on said display being input to the right and left eyes of the observer via the slit pattern wherein said spatial light modulation element drives the respective scanning lines, corresponding to scanning lines of stripe image of said display, of said slit pattern in synchronism with drive of the respective scanning lines of stripe image of said display, or drives the respective pixels, corresponding to respective pixels of stripe image of said display, of said slit pattern in synchronism with drive of the respective pixels of stripe images of said display.

A stereoscopic image display method comprising the steps of:

• sequentially forming, on a display, a single stripe image obtained by arranging and synthesizing some of a plurality of stripe pixels which are obtained by dividing each of right- and left-eye parallax images supplied from a parallax image source having parallax image information, while performing a scanning operation, and
• inputting light transmitted through the stripe pixels, corresponding to right and left eyes of an observer, of the stripe image displayed on said display to the right and left eyes of the observer via a slit pattern, which is obtained by sequentially forming a light-transmission portion and a light-shielding portion at a predetermined pitch on a spatial light modulation element, in synchronism with the scanning operation, wherein said spatial light modulation element drives the respective scanning lines, corresponding to scanning lines of stripe image of said display, of said slit pattern in synchronism with drive of the respective scanning lines of stripe image of said display, or drives the respective pixels, corresponding to respective pixels of stripe image of display, of said slit pattern in synchronism with drive of the respective pixels of stripe image of said display.
