Abstract
This projection-type display device has: an operation signal detection unit that receives operation signals that indicate adjustment content of a projected image, the adjustment content having been instructed by way of an operation unit; an installation state detection unit that detects, as the installation state of the projection-type display device, a first state and a second state realized by rotating 90 degrees around an axis parallel to the optical axis of the projection lens; and a control unit that, upon detecting a signal that corresponds to the first direction by way of the operation signal detection unit in the first state and the second state, adjusts a projected image by shifting the projected image in the first direction or by moving a correction-object site in the projected image in the first direction.
