摘要: A method and apparatus are provided for preventing keystone distortion in a projected image. image (750a) is produced by projecting light from source (102) through deformed (700a) rendered on display device (110) of projector (100) onto viewing surface (130) at non-perpendicular angle. An original (700) received projection proportion to the angle generate (700a), which yield having proportions closely matching (700). The may be resized storage memory and/or fit within specified area (110). further comprises digitizer module (206) receiving resizing it generator (208) Deformation performed either or both (208).
