Patent ID: 8442303

Claim:
An apparatus for constructing a three-dimensional image of an object, said apparatus comprising: a plurality of light sources disposed at different locations but at the same distance from said object; at least one image capturing element for respectively capturing a plurality of two-dimensional images of said object under illuminating by said light sources which are turned on one at a time; an image processing element electrically connected to said image capturing element for generating said three-dimensional image by shape-from-shading algorithm based on said two-dimensional images; and a rotatable stage for supporting said object, wherein the rotatable stage comprises a substrate, a rotatable body, a protrusion structure, a holder, a lever, and a rotatable plate; wherein the substrate provides a rotating force to the rotatable body when the apparatus is operated; wherein the protrusion structure is disposed between the substrate and the rotatable body; wherein the holder is on the rotatable body; wherein the rotatable plate is pivotally connected to the holder and the rotatable plate fixes and rotates said object; wherein the lever is disposed through the rotatable body and connected to the rotatable body; wherein the lever is pivotally connected to the rotatable plate; wherein the lever abuts against the protrusion structure; wherein when the lever is moved to the substrate, the lever is moved to a lower position; wherein when the lever is moved to the protrusion structure, the lever is moved to an upper position.
