1. A three-dimensional image-capturing device, comprising: first and second image sensors; first and second optical systems; a texture image capturing processor that captures a still image of a subject by said first image sensor through said first optical system; a three-dimensional measuring processor that measures distance information about said subject for each pixel of said second image sensor through said second optical system; and a parallax compensation processor that compensates for parallax between said first optical system and said second optical system by said distance information.
