Abstract

A stereoscopic photography system utilizes digital camera technology to create stereoscopic content. The camera has a photosensitive material optically aligned with a lens for capturing images, a viewfinder screen for viewing the images captured on the photosensitive material, and a zoom control for adjusting the focal length of the lens. An optical attachment is securely coupled to the camera lens in a manner that permits adjustment. The optical attachment causes a stereo pair of images to be focused through the lens onto the photosensitive material The camera is coupled to a processor having a first program for digitizing the stereo pair of images and a second program for transforming the digitized stereo pair of images into a predefined format. The transformed images are displayed on a monitor and observed through either a modulating overlay screen or modulating eyewear.

Claims

1. A stereoscopic photography method, comprising:

providing a camera having a lens for focusing an image and a photosensitive material optically aligned with the lens for capturing the image;

securely coupling an optical attachment to the camera lens, said optical attachment being adapted to cause a stereo pair of images to be focused through the lens onto the photosensitive material;

digitizing the stereo pair of images which are captured on the photosensitive material;

transforming the digitized stereo pair of images into a predefined display format; and

displaying the transformed images on a stereoscopic display system that utilizes the predefined display format.

2. A stereoscopic photography method according to claim 1, further comprising aligning the optical attachment to the lens before the secure coupling step.

3. A stereoscopic photography method according to claim 2, wherein the camera further comprises a viewfinder screen for viewing images captured on the photosensitive material, and wherein the alignment step comprises rotating the optical attachment on its lens coupling until a boundary between the stereo pair of images is parallel with an edge of the viewfinder screen.

4. A stereoscopic photography method according to claim 1, further comprising optimizing the focal length of the optical attachment coupled to the lens.
