Abstract: An image forming medium changing device includes a changing unit configured to change a characteristic of an image forming medium on which projected light is focused, wherein the projected light is refocused on an aerial space image forming section by a light guide optical system. A spatial projection apparatus including the image forming medium changing device includes multiple image forming media having different characteristics, and the changing unit is configured to be driven to dispose one image forming medium selected from the multiple image forming media on an image forming effective area interposed between a light source of the projected light and the light guide optical system.

Abstract: A projection control apparatus includes at least one processor or a control processing unit, and a communication unit. The control processing unit obtains a first captured image captured at a first point and a second captured image captured at a second point differing from the first point via the communication unit, obtains first correction data from the first captured image and second correction data from the second captured image, obtains first position data at the first position, second position data at the second point, and third position data at a third point differing from the first and second points, determines third correction data corresponding to the third point using the first correction data, the second correction data, the first position data, the second position data, and the third position data, and corrects a projected image to be projected by a projector based on the third correction data.

Abstract: A detection apparatus includes at least one processing unit, a light guide optical system configured to focus projected light to a spatial image forming plane to form an image thereon, and a sensor configured to shine a laser beam over a set scanning range to detect an entry depth of a target object in a direction orthogonal to the spatial image forming plane and an entry position of the target object on the spatial image forming plane, and the processing unit executes an operation associated with the entry position when the entry depth of the target object reaches a set depth. A display mode of a pointer image is displayed as superimposed on the spatial image forming plane is caused to change step by step in accordance with the entry depth of the target object in a direction orthogonal to the image forming plane which is detected by the sensor.

Abstract: The present invention aims to make it possible to detect deterioration of a housing of a projection apparatus and to notify a user of the deterioration of the housing. A projection apparatus includes at least one processor and an acceleration sensor which detects an inclination of the projection apparatus, in which the processor performs the processes of acquiring a difference between i) a first detection value which is detected by the acceleration sensor in a case where the projection apparatus is installed on an installation surface and ii) a second value which is detected by the acceleration sensor at a time which comes after the installation of the projection apparatus with the projection apparatus on the installation surface, and in a case where the difference becomes more than a threshold value, controlling to notify a warning at a predetermined timing by functioning as a notification unit or to stop functions of the projection apparatus.

Abstract: The present invention aims to make it possible to detect deterioration of a housing of a projection apparatus and to notify a user of the deterioration of the housing. The projection apparatus includes a projected image processing unit which registers a deformation parameter as an initial value in a case where the deformation parameter for a projected image is set as an initial setting to be made at the time of installation of the projection apparatus as a registration control unit. In a case where the deformation parameter for the projected image is adjusted by a user operation after the initial setting is made, the projected image processing unit decides whether an adjustment degree that the deformation parameter is adjusted from the initial value reaches a predetermined threshold value as a decision unit. In addition, in a case where the adjustment degree reaches the predetermined threshold value, the projected image processing unit gives a warning to the user at a predetermined timing as a notification control unit.
