摘要： An image display apparatus acquires a high- quality image by suppressing positional fluctuation of projected dots due to a positional offset of an optical path deflecting element. A spatial light modulation element (1) displays an image by projecting a light from an illumination light source. A projection optical system (3) enlarges and projects the image formed on the spatial light modulation element (1). An optical path deflecting element (2) is provided between the spatial light modulation element (1) and the image formed on a screen (4) so as to deflect an optical path in accordance with a screen frame period. The optical path deflecting element (2) shifts the optical path for the image projected on the screen (4) at a high rate so as to apparently increase a number of picture elements. The optical path deflecting element (2) is located within the projection optical system.

摘要： A video processing apparatus includes an image capturing apparatus and a processing apparatus connected to the image capturing apparatus. The image capturing apparatus includes an image obtaining unit that obtains a frame image; a frame image transmitting unit that transmits the frame image to the processing apparatus; a transformation parameter setting unit that sets transformation parameters received from the processing apparatus in the image capturing apparatus,; an image transforming unit that applies an image transformation to the frame image using the transformation parameters thus set; and a transformed frame image transmitting unit that transmits a transformed frame image to the processing apparatus. The processing apparatus includes a transformation parameter calculating unit that calculates the transformation parameters for the image transformation, using the frame image received from the image capturing apparatus; and a transformation parameter transmitting unit that transmits the transformation parameters to the image capturing apparatus.
