Abstract:
A video display device includes first and second illuminators irradiating a manipulation surface with illumination light for manipulation detection in different directions, an imaging unit employing an imaging element of a rolling shutter system that images the irradiated manipulation surface together with a manipulation object of a user, and a contact point detecting unit detecting a contact point at which the manipulation object of the user touches the manipulation surface based on a captured image of the imaging unit. Captured images of shadows of the manipulation object of the user formed by repeatedly lighting up the first illuminator and the second illuminator alternately are used in a contact point detection process of the contact point detecting unit, and in the alternate lighting of the first illuminator and the second illuminator, a lighting period of one illuminator is longer than an imaging cycle of one frame of the imaging unit.

Claim (Index 8):
A manipulation detection method of detecting a manipulation formed on a manipulation surface by a manipulation object of a user, comprising:\n a step of irradiating the manipulation surface with illumination lights for manipulation detection in different directions through by a first illuminator and a second illuminator; a step of imaging the manipulation surface irradiated with the illumination light together with the manipulation object of the user through an imaging unit that employs an imaging element of a rolling shutter system; and a step of detecting a contact point at which the manipulation object of the user touches the manipulation surface on the basis of a captured image of the imaging unit, wherein in the step of detecting the contact point, captured images of shadows of the manipulation object of the user formed by repeatedly lighting up the first illuminator and the second illuminator alternately are used, and in the step of irradiating with the illumination lights, a lighting period of one illuminator in the alternate lighting of the first illuminator and the second illuminator is longer than an imaging cycle of one frame of the imaging unit.
