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 7):
The video display device according to  claim 6 , wherein the first illuminator, the second illuminator, and the imaging unit are installed on an upper side of the video display surface, and\n in a case in which the non-manipulation region by the user exists on a lower side of the video display surface, the imaging element of the imaging unit is rotated, and an imaging start position is set on the lower side of the video display surface.
