  • Publication number: 20090161028
    Abstract: An image processing apparatus receives first and second input image signals and generates first and second projection image signals for projecting images from first and second projectors so as to be superimposed on a screen. A storage unit stores, for each projection position on the screen, intensity ratios between projected light from the first and second projectors when viewing from first and second viewing position. An intensity correcting unit adds the first and second input image signals in proportions set for generating the first projection image signal and in proportions set for generating the second projection image signal, according to the stored intensity ratios. The first projection image signal is supplied to the first projector and the second projection image signal is supplied to the second projector.

  • Publication number: 20090100767
    Abstract: There is a need for being able to excellently audiovisually receive contents without disordering a room atmosphere. An audiovisual room 1 is provided with one wall including an inner wall 2 and an outer wall 3. Part or all of the innerwall 2 forms a rear-projection screen 6C or a diaphragm (speaker unit) 6A. Equipment such as a projector 10 and an amplifier is placed in a space between the inner wall 2 and the outer wall 3. The space is large enough for a person to enter. Accordingly, a serviceperson etc. can enter the space to easily do works such as maintaining the equipment. The equipment such as the projector is not placed in the audiovisual room 1, making it possible to audiovisually receive contents without disordering a room atmosphere.
