Zusammenfassung:An operation detection device includes: first and second illuminations that irradiate illumination light from different positions onto an operation surface on which a user performs an operation; a camera that captures the operation surface together with an operation part (finger) of the user; a shadow region extraction unit that extracts first and second shadows of the operation part of the user from a captured image obtained by the camera; a contour detection unit that detects contours of each of the first and second shadows extracted; and a touch point detection unit that detects a touch point of the operation part of the user on the operation surface from the distance between the contours.
