Generation and display of stereoscopic images

摘要

A method of displaying successive stereoscopic image pairs comprises: capturing, at a predetermined image rate, a sequence of images suitable for a left eye of a viewer and capturing, at the predetermined image rate, a corresponding sequence of images suitable for a right eye of the viewer; and displaying a sequence of stereoscopic image pairs at the predetermined image rate, in which each displayed stereoscopic image pair comprises one left image suitable for the left eye of the viewer and one right image suitable for the right eye of the viewer, the one left and one right images being derived from the captured sequence of images suitable for the left and right eye of the viewer, respectively; in which: the one left image and the one right image of each stereoscopic image pair are displayed for different respective portions of an image period defined by the predetermined image rate; and the effective temporal position of the one left image of a stereoscopic image pair for display is different to the effective temporal position of the one right image of that stereoscopic image pair.

1. A method of displaying successive stereoscopic image pairs, the method comprising:
capturing, at a predetermined image rate, a sequence of images suitable for a left eye of a viewer and capturing, at the predetermined image rate, a corresponding sequence of images suitable for a right eye of the viewer; displaying a sequence of stereoscopic image pairs at the predetermined image rate, in which each displayed stereoscopic image pair comprises one left image suitable for the left eye of the viewer and one right image suitable for the right eye of the viewer, the one left and one right images being derived from the captured sequence of images suitable for the left and right eye of the viewer, respectively; in which:
the one left image and the one right image of each stereoscopic image pair are displayed for different respective portions of an image period defined by the predetermined image rate;an effective temporal position of the one left image of a stereoscopic image pair for display is different from an effective temporal position of the one right image of that stereoscopic image pair;each image of the captured sequence of images suitable for the left eye of the viewer is captured at the same instant as a corresponding image of the captured sequence of images suitable for the right eye of the viewer; and processing at least one of the captured sequences of images so that, for each stereoscopic image pair from the sequence of stereoscopic image pairs, the effective temporal position of the one left image of that stereoscopic image pair is different to the effective temporal position of the one right image, the processing step comprising interpolating one of the left image and the right image of each stereoscopic image pair from two or more of the captured sequence of images suitable for the left and right eye of the viewer, respectively, the interpolated left and/or right image having a different effective temporal position to the captured images from which that interpolated image is derived, and applying a delay to the other of the left image and the right image of each stereoscopic image pair.
