Patent ID: 8314894

Claim:
A projection type display comprising: an image processing unit for processing an input image; an illumination optical block for radiating an optical beam; a liquid crystal panel for modulating the optical beam radiated from said illumination optical block with an output signal from said image processing unit and outputting the modulated optical beam; and a projection lens block for projecting the modulated optical beam output from said liquid crystal panel upon a projection object, wherein said image processing unit comprises: a first image rotation unit for rotating the input image by a first angle; a second image rotation unit for rotating the input image by a second angle; a two-image synthesizing unit for synthesizing a first output image from said first image rotation unit and a second output image from said second image rotation unit into one image; said first image rotation unit or said second image rotation unit executes a scaling process including magnification and reduction of an input image; and said first image rotation unit or said second image rotation unit executes a scaling process including magnification, reduction and geometrical distortion correction of an output image from said two-image synthesizing unit.
