Abstract
Two pictures of a subject obtained by objective lenses and from different locations of viewpoint are respectively rotated by dove prisms, 90 degrees clockwise, and then merged into a single picture by total reflection mirrors. The picture after synthesis is reduced at a predetermined ratio by a condenser lens, and then projected onto a pickup plane of a CCD. It is therefore possible to obtain stereoscopic pictures having parallax as a single picture using a single camera without narrowing the effective fields of view of right and left pictures of different viewpoints.
Claims5
A stereoscopic picture obtaining device for obtaining a stereoscopic picture by combining a first picture of a subject viewed from a first viewpoint and a second picture of the subject viewed from a second viewpoint having parallax with respect to the first viewpoint, said stereoscopic picture obtaining device comprising:
- first and second objective lenses adapted to simultaneously capture the first picture of the subject viewed from the first viewpoint and the second picture of the subject viewed from the second viewpoint, respectively;
- picture rotating means for rotating the first and second pictures about respective optical axes of said first and second objective lenses by 90 degrees in a state where the first and second pictures are disposed on a same plane before and after rotation;
- picture merge means for merging the first and second pictures rotated by said picture rotating means into a single picture through an optical operation so that an upper side of the first picture viewed from the first viewpoint before rotation coincides with a lower side of the second picture viewed from the second viewpoint before rotation;
- picture reducing means for reducing the single picture obtained by said picture merge means at a predetermined reduction ratio, and projecting the reduced picture onto a predetermined projection plane;
- and
- an image pickup device operable convert the picture projected onto a pickup plane which is arranged on the projection plane into image data.
A stereoscopic picture obtaining device for obtaining a stereoscopic picture by combining a first picture of a subject viewed from a first viewpoint and a second picture of the subject viewed from a second viewpoint having parallax with respect to the first viewpoint, said stereoscopic picture obtaining device comprising:
- two image taking means for simultaneously shooting the subject viewed from the first viewpoint and the subject viewed from the second viewpoint, and generating two sets of image data representing two images;
- image rotating means for rotating the two images represented by the two sets of image data about respective optical axes of said two image taking means by 90 degrees in a state that the two images are disposed on a same plane before and after rotation;
- image merge means for merging the two images rotated by said image rotating means into a single image through an electrical operation so that an upper side of the image viewed from the first viewpoint before rotation coincides with a lower side of the image viewed from the second viewpoint before rotation;
- image reducing means for reducing the single image obtained by said image merge means at a predetermined reduction ratio through an electrical operation;
- and
- storage means for storing image data representing the reduced image obtained by said image reducing means.
