Abstract

A projection display apparatus includes an image generation unit that generates an image light, an optical system that projects the image light onto a projection plane, an optical path changing unit that changes a display position of the image light on the projection plane, and a controller. The controller generates signals for plural types of sub-frames by dividing spatially a signal for each frame of the video input signal. The controller controls the optical path changing unit to keep the display position of the image light on the projection plane before and after transition of the frame of the video signal, and controls the image generation unit to make a type of a beginning sub-frame in a frame output just after the transition equal to a type of a last sub-frame in a frame output just before the transition.
