A projection display apparatus according to embodiments includes a light source that emits color component light beams of a plurality of colors and an imager that modulates the color component light beams of a plurality of colors emitted from the light source. The projection display apparatus includes an element control unit that controls the imager; and a light source control unit that controls the light source. The element control unit controls the imager based on an image output signal obtained by a signal expansion process of an image input signal. The light source control unit performs a power reduction process of reducing power supplied to the light source according to an expansion amount of the image input signal expanded by the signal expansion process. The light source control unit performs a light emission period control process of adjusting light emission periods of a color component light beams of a plurality of colors emitted from the light source within a 1-frame period according to the image input signal.

A camera for capturing an object that will enter a projection space is attached to the casing of a projection display apparatus. The camera is installed at the position in which, when the camera faces the projection plane, at least one of the back direction and the side direction of the casing is included within the filed of view of the camera. For example, the cameras are installed on both side edges of the casing so as to face each other.

A projection display apparatus includes an imager that modulates light emitted from a light source and a projection unit that projects light emitted from the imager on a projection surface. The projection display apparatus includes: an imager controller that controls the imager to display a test pattern image in which a characteristic point is defined by at least three adjacent regions; an acquisition unit that acquires a captured image of the test pattern image from an imaging element configured to capture the test pattern image projected on the projection surface; and an adjustment unit that identifies the characteristic point included in the captured image on the basis of the captured image acquired by the acquisition unit and adjusts an image to be projected on the projection surface on the basis of the identified characteristic point. The at least three adjacent regions surround the characteristic point and are adjacent to the characteristic point.
