Abstract: An information processing apparatus causes a display apparatus to display a superimposed image obtained by superimposing a material image applied with transmission processing on a captured image obtained by imaging a projection target object, which is a projection target of an image from a projector, with a camera and a user interface image for receiving an input for determining a position of the camera. The information processing apparatus generates projection image data representing a projection image by correcting the material image according to a three-dimensional shape measured based on a captured image obtained by imaging, from the determined position, with the camera, the projection target object onto which a pattern image for three-dimensional measurement is projected from the projector and outputs the projection image data to the projector.

Abstract: A projector includes: a projection unit; a detection light irradiation unit which radiates detection light onto a detection area which is set corresponding to a display area of the projection unit; an image pickup unit which receives reflected light of irradiation detection light reflected in the detection area; and a control unit which carries out detection of an operation of a non-light-emitting pointing element and detection of an obstacle blocking the detection light, and causes the projection unit to display information about the obstacle.

Abstract: A control method of controlling an emission direction of light emitted toward a display surface to be executed by a detection device configured to include an emission section and detect an irradiation position of the light includes the steps of determining whether or not the irradiation position of the light in the display surface is located in a target area, controlling the emission direction of the light to a direction of moving the irradiation position toward the target area when determining that the irradiation position is not located in the target area, and sets an amount of movement of the irradiation position toward the target area by control of the emission direction of the light larger when the irradiation position is located in a first region compared to when the irradiation position is located in a second region between the target area and the first region.

Abstract: An operation method to be executed by a display device including an emission section configured to emit detection light used to detect a pointing body configured to point a display surface along the display surface includes the steps of determining whether an obstacle blocking at least a part of the detection light exists or not based on first imaging data generated by imaging the display surface, and moving, when determining that the obstacle exists, the emission section to thereby make a distance between the display surface and the emission section in a normal direction of the display surface longer than a distance between the display surface and the emission section in the normal direction at a moment of a determination that the obstacle exists.

Abstract: A projector includes: a first camera which receives light emitted from a self-light-emitting pointing element; a position detection unit which detects an operation of the self-light-emitting pointing element to a detection area, based on a light reception state of the first camera; and a light emission control unit which calculates a light emission intensity of the self-light-emitting pointing element, based on distance information from an end part of the detection area to the first camera.

Abstract: A projector includes: a position detection unit which detects a position pointed by a light pen (first pointer) and a position pointed by a user's finger or the like (second pointer) within a detection area; a state determination unit which determines a pointing direction of the light pen; and an invalid area setting unit which sets an invalid area where the position pointed by the second pointer is invalid, within the detection area, based on the position pointed by the light pen detected by the position detection unit and the pointing direction of the light pen determined by the state determination unit.
