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.
