Abstract: Television broadcasting systems (Figure 1, element 30) of this invention comprise an imaging system (32), and transmission system (90), and a displaying system (100). The imaging system (32) captures two-dimensional images of an object at different focal plane, and generates an all-in-focused image and depth profile. A data signal carrying the image data is generated and transmitted over a broadcasting system (90) compatible with commercial two-dimensional television broadcasting, cable, and/or alternative systems. The depth profile is transmitted by using vacant space in video/audio signal within the allocated channel bandwidth. The data signal is received by the displaying system (100) and the extracts the all-in-focused image (82) and depth information (84) from the data signal. The object is restored from all-in-focused image and depth profile and displayed on the displaying system (100) as a three-dimensional spatial image (98). Viewers having conventional two-dimensional display device (96) can watch enhanced two-dimensional images.

Abstract: A three-dimensional display device includes a two-dimensional display displaying a first image, and a variable focusing lens receiving light from the two-dimensional display and forming a second image. The variable focusing lens reflects light from the two-dimensional display. The first image includes a predetermined number of first depthwise images that are displayed within a unit time, and the second image includes corresponding second depthwise images. Each depthwise image represents the portion of the first image having the same image depth, and the two-dimensional display displays one depthwise image at a time. The focal length of the variable focusing lens changes according to the depth of the depthwise image being displayed. A micromirror array lens is used as the variable focusing lens. The micromirror array lens has enough speed and focusing depth range for realistic three-dimensional display.

Abstract: A variable focus lens comprises: a plurality of microlenses into which light falls incident; a plurality of first microprisms which are positioned respectively corresponding to the plurality of microlenses, and which cause the path of incident light from the corresponding microlens to change to a first direction, based on a predetermined first tilt angle; and a plurality of second microprisms which are positioned respectively corresponding to the plurality of first microprisms, and which cause the path of incident light from the corresponding first microprism to change to a second direction at right angles to the first direction, based on a predetermined second tilt angle. And, here, the focal points of the microlenses, the first tilt angle of the first microprisms and the second tilt angle of the second microprisms are adjusted in such a way that the light incident on the microlenses collects at any one point.
