Abstract: A projector includes a cooling fan, and a processor, and the processor executes, in a case in which the cooling fan is operating in a first revolution speed mode, a control of switching an operation mode of the cooling fan to a second revolution speed mode whose revolution speed is faster than that of the first revolution speed mode in a case in which an obtained temperature detection value reaches a first threshold, and executes, in a case in which the cooling fan is operating in the second revolution speed mode, a control of switching the operation mode of the cooling fan to a revolution speed mode whose revolution speed is slower than that of the second revolution speed mode in a case in which an obtained temperature detection value decreases below a second threshold which differs from the first threshold.

Abstract: A projection control device includes a hardware processor. The hardware processor acquires a feature of a projection surface. The hardware processor determines a first area in which a first projection image corrected based on the acquired feature of the projection surface is projected and a second area that is other than the first area and in which a second projection image corrected based on the feature of the projection surface is projected, within a projection area projectable, by a projection device, on the projection surface. Then, the hardware processor controls the projection device to project the first projection image in the first area and project the second projection image in the second area.

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.
