Abstract
The image recognition device includes a measurement point determination section adapted to detect a finger located between a camera and a screen from an image obtained by the camera, and determine a fingertip of the finger, a linear pattern display section adapted to make a projector display a linear pattern on an epipolar line which passes through the fingertip and is determined from a positional relationship between the camera and a projector, and a pattern determination section adapted to determine, from an image including the linear pattern obtained by the camera, a difference between the linear pattern included in that image, and the linear pattern in a case in which the fingertip is absent.
