Claim 0:
1. A 3D image-capturing device, comprising:
at least one camera that acquires a 2D image and distance information of an object;
a monitor that displays the 2D image acquired by the camera; and
at least one processor including hardware,
wherein the processor acquires a first area for which the distance information is not required in the 2D image displayed on the monitor, and
sets an image-capturing condition so that an amount of the distance information acquired by the camera in the acquired first area is less than or equal to a prescribed first threshold and an amount of the distance information acquired by the camera in a second area, which is at least part of an area other than the first area, and is greater than a prescribed second threshold that is larger than the first threshold,

wherein there are two cameras provided, and the cameras are spaced apart in a direction that intersects an optical axis, and
the processor calculates a parallax between parts of two 2D images by matching small areas in the two 2D images acquired by the two cameras, and calculates the distance information on the basis of the calculated parallax.
