ABSTRACT:
A method and apparatus for producing orthostereoscopic composite images in a camera having a large-aperture taking lens to form 2D images of a scene through different aperture sections on a photosensitive medium. An aperture plate having at least one window is used to select the viewing angles of the 2D images by controlling the light transmission path through the taking lens. Only one aperture section is opened at a time to allow the taking lens to form a 2D image. Each 2D image is divided into a plurality of linear segments each having a number of image bands each corresponding to an aperture section. A line-masking device such as a LCD panel comprising a plurality of linear strips can be used to allow in each 2D image only the image bands corresponding to the opened aperture section to form part of the composite image. The composite image can be displayed behind a lenticular screen or a parallax barrier for 3D viewing.
