PURPOSE:To achieve the higher performance of the stereoscopic image display device by making the size of the picture elements of the original image in the same direction as the lengthwise direction of the circular cylindrical lenses of a renticular longer than the direction perpendicular to this and arraying plural primary colors in the lengthwise direction of the picture elements. CONSTITUTION:If the pitch of the configuration of the circular cylindrical lenses of the renticular plate is let lambda and the number of channels N, then the transverse width of a picture element 9 is the same lambda/4 as that of striped images 8. The picture element 9 is trisected in three primary colors R, G, B in the longitudinal direction. At this time, the length a' of the picture element 9 is made larger than the transverse width and the size of the picture element of one color is made approximately the same longitudinally and cross. The original color is constituted by 4 channels and if one stripe image C is viewed by the eye 12, the transverse width of the picture elements becomes lambda and is magnified 4 times. According to this, the longitudinal size of the picture elements is magnified to less than about lambda within the range where the effect upon the resolution of the reconstructed image of the original picture is small and the respective elements of the three primary colors are arrayed longitudinally. In this way, the performance of the stereoscopic image display device is improved and this is also applied to color televisions. |
