Abstract
A mechanism, employed for a camera, which obtains precise information upon a three-dimensional configuration of an object, without its being affected by nature of the object and/or by nature of a light with which the object is lit. The mechanism includes an image-taking apparatus, a projection apparatus for selectively projecting more than two types of pattern lights onto a photographing area, and a detecting apparatus for detecting a photographing condition about the object and/or the light. The projection apparatus selectively projects one of the pattern lights on the basis of a result of detection, executed by the detecting apparatus, of the photographing condition about the object and/or the light.
