A three dimensional image is derived from two-dimensional images. At least one of the two-dimensional images has a predetermined number of pixels. Depth measurements are derived from the two-dimensional images. The number of derived depth measurements is substantially equal to the predetermined number of pixels. The three-dimensional image is derived from the two-dimensional digital images and the depth measurements.

[ What is claimed is:] [1.]1. A method for analyzing pixel image information of a three-dimensional object to produce depth information, the depth information representing relative positions of respective points along a surface of said object, the relative positions being defined along a direction parallel to a portion of an optical path for imaging said object, the portion of the optical path including light directly reflected from the surface of said object, said method comprising:determining a contrast measurement of a given area of said object using pixel information from each of at least three images of at least a portion of said object, each of said images being obtained with a different structured illumination andconverting said contrast measurement to depth information.
