Abstract
A method for crosstalk compensation of stereoscopic images for three-dimensional projection is disclosed. The method can be used for producing a stereoscopic presentation containing stereoscopic image pairs that incorporate density or brightness adjustments to at least partially compensate for crosstalk contributions from images exhibiting differential distortion.
Claims14
A method for producing a stereoscopic presentation containing a plurality of stereoscopic image pairs for projection by a projection system, comprising:
- (a) determining distortion information associated with a first and second projected images of a stereoscopic image pair;
- (b) determining crosstalk percentage for at least one region of the projected images of the stereoscopic image pair;
- (c) determining a crosstalk value for at least one pixel of the first projected image of the stereoscopic image pair based in part on the determined distortion information and the crosstalk percentage;
- (d) adjusting brightness of the at least one pixel to at least partially compensate for the crosstalk value;
- (e) repeating steps (c) and (d) for other pixels in other images in the stereoscopic presentation;
- and
- (f) recording the stereoscopic presentation by incorporating images with brightness adjusted pixels.
A plurality of stereoscopic images for use in a stereoscopic projection system, comprising:
- a first set of images and a second set of images, each image from one of the two sets of images forming a stereoscopic image pair with an associated image from the other of the two sets of images;
- at least some images in the first set of images incorporating brightness-related adjustments for at least partially compensating for crosstalk contributions from the associated images in the second set of images;
- at least some images in the second set of images incorporating brightness-related adjustments for at least partially compensating for crosstalk contributions from the associated images in the first set of images;
- and
- wherein the crosstalk contributions from respective images in the first and second sets of images are determined based in part on distortion information associated with projection of the stereoscopic images.
