Abstract

A projection device and an information processing method are described. The projecting device includes a display image generation unit for generating a plurality of frames of the continuous images to be displayed; a light source unit for receiving the plurality of frames of the continuous images to be displayed generated by the display image generation unit and forming a corresponding set of the light rays sequentially; a light path transformation unit having N kinds of optical states, N is the natural number greater than 1; a projecting unit for projecting the light rays inputted to it to the first to Nth projection regions; and a control unit for controlling the light source unit so that the images to be displayed are switched in a predetermined frequency, and for controlling the light path transformation unit so that the N kinds of optical states are switched in the predetermined frequency.

Description

technical field [0001] The present invention relates to a projection device and an information processing method used therefor, and more specifically, to a projection device capable of simultaneously displaying multiple screens with only one projection device and the contents of the multiple screens are different from each other and information used therefor Approach. Background technique [0002] A projector is widely used in presentations and home theaters, and it is a projection device used to enlarge and display images. At present, it has been applied to presentations in conference rooms and watching movies on a large screen by connecting DVD players and other devices at home.
