Patent ID: 7412113

Claim:
A captured image projection apparatus for image-capturing a written material by a camera supported by a camera mounting and projecting a captured image obtained by the image-capturing on a screen, said apparatus comprising: a first inclination angle detection section which detects an inclination angle of said camera which is produced by an image capturing direction of said camera and a first vertical line; a second inclination angle detection section which detects an inclination angle of said camera mounting which is produced by a perpendicular line drawn towards said camera mounting and a second vertical line; a calculation section which calculates an image capturing angle of said camera to the written material, based on both of the inclination angle of said camera and the inclination angle of said camera mounting detected by said first and second inclination angle detection sections; and a correction section which corrects an inclination of the captured image, based on the image capturing angle calculated by said calculation section.
