Abstract

Abstract The technique uses a viewing lenticular lens sheet constituted by an array of lenticular lenses on which a combined image obtained by combining pixels for the right and left eye images having binocular disparity data. This technique comprises the steps of : detecting a position of the viewer ; and changing positions of the pixels for the right and left eye images on the combined image in accordance with the detected position of the viewer, so that the right and left eye images are always correctly provided to the right and left eyes of the viewer.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
A technique of stereoscopic image display for providing right and left eye images to right and left eyes of a viewer using a viewing lenticular lens sheet constituted by an array of lenticular lenses on which a combined image obtained by combining pixels for the right and left eye images having binocular disparity data, comprising the steps of: detecting a position of the viewer; and changing positions of the pixels for the right and left eye images on the combined image in accordance with the detected position of the viewer, so that the right and left eye images are always correctly provided to the right and left eyes of the viewer.
Claim 2
Dependent Claim 111 words
A technique of stereoscopic image display for providing right and left eye images to right and left eyes of a viewer using a viewing lenticular lens sheet constituted by an array of lenticular lenses on which a combined image obtained by combining pixels for the right and left eye images having binocular disparity data, comprising the steps of: detecting a position of the viewer; and changing positions of the pixels for the right and left eye images on the combined image in accordance with the detected position of the viewer, so that the right and left eye images are always correctly provided to the right and left eyes of the viewer.
Claim 3
Dependent Claim 52 words
A technique according to claim 1, wherein said technique is realized by an arrangement in which a repetitive pitch of said lenticular lenses of said lenticular lens sheet is set to be smaller than a repetitive pitch of pairs of pixels for the right and left eye images on the combined image.
Claim 4
Dependent Claim 67 words
A technique according to claim 1 or 2, wherein one lenticular lens corresponds to one pair of pixels for the right and left eye images on the combined image, and the step of changing the positions of the pixels for the right and left eye images on the combined image includes the step of replacing the positions of the pixels for the left and right eye images.
Claim 5
Dependent Claim 59 words
A technique according to claim 1 or 2, wherein each of the pixels for the right and left eye images corresponding to one lenticular lens is constituted by a plurality of micropixels, and the step of changing the positions of the pixels for the right and left eye images on the combined image is executed in units of micropixels.
Claim 6
Dependent Claim 39 words
A technique according to any one of claims 2, 3, and 4, wherein the combined image comprises the right and left eye images displayed by a display device arranged behind a rear surface of said viewing lenticular lens sheet.
Claim 7
Dependent Claim 66 words
A technique according to any one of claims 2, 3, and 4, wherein the combined image comprises an image obtained by focusing the right and left eye images projected from a plurality of projectors arranged on the side of the viewer on a diffusive layer arranged on a rear surface of said viewing lenticular lens sheet by said lenticular lenses of said viewing lenticular lens sheet.
Claim 8
Dependent Claim 85 words
A technique according to any one of claims 2, 3, and 4, wherein the combined image comprises an image obtained by focusing the right and left eye images projected from a plurality of projectors arranged on a side opposite to the viewer with respect to said viewing lenticular lens sheet on a diffusive layer arranged on a rear surface of said viewing lenticular lens sheet by lenticular lenses of a lenticular lens sheet having the same performance as that of said viewing lenticular lens sheet.
