Disclosed are methods and apparatus for producing images for stereoscopic, three-dimensional viewing generated with existing mobile graphical devices, such as cameras, video recorders, PDAs, telephones, and other devices, such as the iPhone™. Two reflectors, which may be mirrors or prisms, are positioned to separate the field of view of a camera lens on the mobile graphical device into a direct field of view and an offset field of view and to record and display the separated fields in a two-paned format on the mobile graphical device. Eye lenses are used to separately view the split images. An integrated housing and cradle receive the mobile graphical device and are coupled to the reflectors and the eye lenses. An area of each pane may be provided to display control icons for three-dimensional viewing, and a control area may be provided out of view on a touch screen for user control.

Three-dimensional information is presented directly on the surface of a target three-dimensional object without using a display device such as a display monitor and an HUD. Spatially coded light patterns are projected from two projectors on a target object surface. The light projected from the two projectors are added up on the object surface to produce unified color and luminance. On the object surface, light is simply added up, so that a pattern whose color and brightness correspond to distance and height appears. Hence, a distance to an object or a three-dimensional shape of an object can be highlighted by the color and brightness presented on the object for perception by human beings.

A single-lens 2D/3D camera has a light valve placed in relationship to a lens module to control the light beam received by the lens module for forming an image on an image sensor. The light valve has a light valve area positioned in a path of the light beam. The light valve has two or more clearable sections such that only one section is made clear to allow part of the light beam to pass through. By separately making clear different sections on the light valve, a number of images as viewed through slightly different angles can be captured. The clearable sections include a right section and a left section so that the captured images can be used to produce 3D pictures or displays. The clearable sections also include a middle section so that the camera can be used as a 2D camera.
