Embodiment Construction

[0043] The conversion of one or more non-stereo cameras to stereo cameras is described. As previously mentioned, a non-stereo camera can be used to capture a scene by capturing a first image of a scene from a first perspective, and then moving the non-stereo camera to a second position to capture another image of the scene from another perspective. Anaglyph. However, the stereoscopic image processing software of a mobile device with a built-in camera does not know how far the camera has moved. Therefore, there are no absolute scale factors available for stereo image processing software.

[0044] Currently available smartphones typically have two cameras - a front camera and a rear camera. Since the cameras are facing in opposite directions, they are non-stereo cameras. However, if the optics can change the effective position and effective orientation of one of these cameras, the front and rear non-stereo cameras can be provided with overlapping fields of view, making it pos...

Abstract

The present invention describes methods, apparatus and apparatus for converting a non-stereo camera to a stereo camera. At least one optical element may be used to temporarily change the effective position and effective orientation of the first non-stereoscopic camera. The changed effective position may be displaced a predetermined distance from the effective position of the second non-stereo camera, and the changed effective orientation may provide the first non-stereo camera with a field of view that overlaps that of the second non-stereo camera. At least one optical element may be used to capture the first image with the first non-stereo camera. The second image may be captured by a second non-stereo camera. The second image may have a frame of reference displaced by a predetermined distance from the frame of reference of the first image.

Description

[0001] cross reference [0002] This patent application claims priority to U.S. Patent Application No. 14 / 055,157, filed October 16, 2013, by Rose et al., entitled "Conversion of at Least One Non-Stereo Camera into a Stereo Camera," which has been assigned to the assignee of this application. Background technique [0003] The following relates generally to stereo cameras, and more specifically to converting at least one non-stereo camera to a stereo camera. [0004] A non-stereo camera captures a single image from a single viewpoint in time. Currently, when a non-stereoscopic camera is used to capture stereoscopic photos, a user can capture a first image of a scene from a first perspective, and then move the camera to a second position to capture another image of the scene from another perspective. However, the stereoscopic image processing software of a mobile device with a built-in camera does not know how far the camera has moved. Therefore, for stereoscopic image proces...
