1. A three-dimensional image-capturing device using a pattern projection method, comprising:

  • a first image capturer that captures a pattern image produced by light in a first range;

    a second image capturer that captures a texture image produced by light in a second range which is different from said first range;

    a first optical element that selectively cuts off light in said second range and that is disposed in a first light path through which light rays received by said first image capturer pass;

    a second optical element that selectively cuts off light in said first range and that is disposed in a second light path through which light rays received by said second image capturer pass;

    a pattern projector that projects a predetermined pattern onto a subject using light in said first range; and

    an optical-system adjuster that adjusts an intersection of a first principal ray from a center of said pattern image and a second principal ray from a center of said texture image to intersect on the subject;

    wherein said pattern image and said texture image can be simultaneously captured while said predetermined pattern is projected onto the subject by said pattern projector.
