Abstract
Official abstract text for this publication.
A projection display device includes an optical modulation element configured to modulate light outputting from a light source, and a projection unit configured to project light modulated by the optical modulation element on a projection screen. The projection display device includes an element control unit that controls the optical modulation element to display a test pattern image, an acquiring unit that acquires an image obtained by capturing the test pattern image from an image capture element that captures the test pattern image projected on the projection screen, and an adjusting unit that adjusts an image projected on the projection screen on the basis of the capture image acquired by the acquiring unit. The element control unit controls the optical modulation element such that a guidance image that guides focus adjustment of the image projected on the projection screen is displayed.
First claim
