Abstract
A projection-type display device includes: an operation signal detector, configured to receive an operation signal that indicates adjustment content of a projected image that was instructed by way of an operation unit; an installation state detector, configured to detect, as an installation state of the projection-type display device, a first state and a second state that is rotated 90 degrees from the first state around an axis that is parallel to an optical axis of a projection lens; and a controller that, upon detecting a signal that corresponds to a first direction by way of the operation signal detector in the first state and the second state, adjusts the projected image by causing the projected image to shift in the first direction, or adjusts the projected image by causing a correction-object site in the projected image to move in the first direction.
