Abstract
The present invention provides a projection display apparatus realizing easy recognition of the effect of registration adjustment. The projection display apparatus includes: a light source; a spatial light modulation device modulating, on the basis of a video signal, each of primary color lights for color display emitted from the light source; projecting means for projecting, onto a screen, each of the primary color lights modulated by the spatial light modulation device; and correcting means for correcting, based on a given correction value, the video signal for each of the primary color lights so as to reduce misregistration between the primary color lights projected on the screen, and supplying the corrected video signal to the spatial light modulation device. Validation/invalidation of correction on the video signal by the correcting means is switched in accordance with an operation from the user.
