Claim One:
1. An input operation detection device configured to detect an input operation input to an image, displayed on a surface, by a user, comprising: a first imaging section that includes a first imaging optical system and a first image sensor; a second imaging section that includes a second imaging optical system and a second image sensor; and a processor configured to detect the input operation based on projection data acquired by the first imaging section and the second imaging section, wherein the image displayed on the surface is divided into a first image and a second image with respect to a first direction, the first imaging section is configured to capture the first image and the second imaging section is configured to capture the second image, an optical axis of the first imaging optical system intersects with the image at an intersection point on a same side as an installation position side of the first imaging section with respect to a center of the first image in the first direction, and an optical axis of the second imaging optical system intersects with the image at an intersection point on a same side as an installation position side of the second imaging section with respect to a center of the second image in the first direction.
