Method and apparatus for acquiring image of internal structure, and computer product

An apparatus for acquiring an internal-structure image of an object from a plurality of images of the object, the apparatus comprising:na photographing unit to photograph the object by capturing light reflected from the object, the light radiated from at least one of a plurality of light sources;a control unit to control the photographing unit and the at least one light source to obtain a first image and a second image under different photographing conditions in which angles formed by the at least one light source, convexity/concavity on surface of the object, and the photographing unit are different; andan extracting unit to extract a third image that is common to the first image and the second image, the third image corresponding to the internal-structure image.

A method of acquiring an internal-structure image of an object from a plurality of images of the object photographed by a photographing unit, the method comprising:nphotographing a first image of the object by capturing light reflected from the object, the light radiated from at least one of light sources;controlling the photographing unit and the light source to change photographing conditions such that angles formed by the light source, convexity/concavity on surface of the object, and the photographing unit are different;photographing a second image of the object by capturing the light reflected from the object; andextracting a third image that is common to the first image and the second image, the third image corresponding to the internal-structure image.

A computer-readable recording medium that stores a computer program for acquiring an internal-structure image of an object from a plurality of images of the object photographed by a photographing unit, wherein the computer program causes a computer to execute;nphotographing a first image of the object by capturing light reflected from the object, the light radiated from at least one of light sources;controlling the photographing unit and the light source to change photographing conditions such that angles formed by the light source, convexity/concavity on surface of the object, and the photographing unit are different;photographing a second image of the object by capturing the light reflected from the object; andextracting a third image that is common to the first image and the second image, the third image corresponding to the internal-structure image.
