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 10):
The manipulation detection method according to  claim 8 , wherein in the step of irradiating with the illumination lights, image capturing completion of each frame of the imaging unit is detected, and the lighting of the first illuminator and the second illuminator is switched each time imaging of k (k is an integer of 3 or more) frames is completed, and\n in the step of detecting the contact point, an image of a frame unit irradiated with only the illumination light of one of the first illuminator and the second illuminator is used, but images of a plurality of frames being imaged before illuminator switching is completed after the illuminator switching starts with the detection of the image capturing completion are not used.
