ABSTRACT:
A projection-type image display apparatus includes a projected-image generating device arranged to display a projected image by projecting image light onto a projection plane, a detector for detecting a positional deviation of the projected image from a predetermined position on the projection plane, and a corrector for correcting the positional deviation of the projected image according to a result of detection by the detector.
