Abstract

An image projection device includes a distance measuring device which determines a screen distance between the image projection device and a screen. An image sensor captures a shape of the screen and a screen detector detects a sensor-view shape of the screen from the captured image of the screen. The sensor-view shape of the screen is transformed to a projector-view shape of the screen by a coordinate transformer based on the screen distance. A controller modifies an image to be projected so as to fit it to the projector-view shape of the screen. The modified image is projected on the screen.
