A laser system for generation of three-dimensional (3D) colored images is based on semiconductor laser sources generating laser light at a plurality of wavelengths. The laser source for each basic color range (red, green and blue) is formed on a single chip. The chip can be an array of the distributed feedback lasers or an array of distributed Bragg reflector lasers, each of which generates laser light at its own wavelength, or a COMB laser generating laser light at a plurality of wavelengths.

All light illuminates a two-dimensional (2D) display, and the light transmitted through the display or reflected by the display at a given color range impinges on an optical unit, containing a first optical element, e.g., a lens or a mirror, the focal length of which is wavelength-sensitive. Light at different wavelengths forms 2D images at different depths. Then, once the images created by the display and the laser pulses at each wavelength are synchronized, all images of the given colored range are perceived by the human's eyes as a single 3D image of this color range.

To fuse 3D images in red, green and blue that are formed at different positions, an optical element, e. g., a lens or a mirror is employed, the focal length of which is adjustable by mechanical motion, or deformation, or applying an electro-optic effect in an electric field. This optical element can be either the same first element with the wavelength-dependent focal length, or a different element. Then, once the light is switched between red, green and blue color ranges, the adjustable focal length of this element is adjusted such to compensate a change of the focal length of the first element, and the focal length of the entire optical unit is restored. Then the human's eyes average the perceived light and see a smoothly moving fully colored 3D image.

An object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation. Another object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation on the basis of ergonomics. The I/O device includes a display device that can generate a stereoscopic image, a depth level sensor that measures a distance to an object, and a control unit that performs display on the display device in accordance with the depth level sensor. A detection region of the depth level sensor has a width in the depth level direction of the depth level sensor, and is composed of a curved measurement region, such that the radius of curvature on the far side in the depth level direction of the depth level sensor is different from the radius of curvature on the near side in the depth level direction of the depth level sensor.

To enhance a mono-output-only controller such as a mobile OS to support selective mono/stereo/mixed output, a stereo controller is instantiated in communication with the mono controller. The stereo controller coordinates stereo output, but calls and adapts functions already present in the mono controller for creating surface and image buffers, rendering, compositing, and/or merging. For content designated for 2D display, left and right surfaces are rendered from a mono perspective; for content designated for 3D display, left and right surfaces are rendered from left and right stereo perspectives, respectively. Some, all, or none of available content may be delivered to a stereo display in 3D, with a remainder delivered in 2D, and with comparable content still delivered in 2D to the mono display. The stereo controller is an add-on; the mono controller need not be replaced, removed, deactivated, or modified, facilitating transparency and backward compatibility.
