A spatial projection apparatus is provided. The apparatus includes an optical medium that diffuses a projected light. The apparatus further includes a light guide optical system that guides the projected light diffused by the optical medium and forms an image on a spatial imaging unit. The optical medium can be formed with a plate shape, a film shape, a three-dimensional shape including unevenness, in smoke-form, fluid-form, or mist-form.

Spatial projection apparatus, spatial projection system, and spatial projection method

A detection apparatus includes at least one processing unit, a light guide optical system configured to cause projected light to focus on a spatial image forming plane to form an image thereon, and a camera configured 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 based on an image captured in such a manner that the spatial image forming plane is included within an angle of view, and the processing unit executes an operation associated with the entry position when the entry depth of the target object reaches a set depth.

Detection apparatus, detection method, and spatial projection apparatus

A projector is configured to, in response to a temperature detection value acquired from one or more temperature detection sensors that detect a temperature of a light source unit reaching a set value, reduce a current ratio flowing through the light source unit; and in response to the reduced current ratio falling below a first set ratio, execute a first process.

Projector, temperature control method of projector, and storage medium

A projection processor includes a processing unit, and the processing unit obtains information concerning a first projected image which is projected by a projector to be formed on an image forming medium and corrects information concerning a second projected image which is formed on the image forming medium as projected light, which is to be refocused on an aerial space image forming section by a light guide optical system, based on the information concerning the first projected image obtained.

Projection processor, spatial projection apparatus, spatial projection system, and spatial projection method

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.
