Abstract
A control device of a projection system including an optical system that projects an image generated in a display portion based on input image data to a projection object, and an imaging portion that images the projection object, includes: a distance determination portion that acquires first captured image data of the image projected to the projection object from the imaging portion and determines a distance from an object present between the projection object and the optical system to the optical system based on a first sharpness of a part or an entire part of the first captured image data and a second sharpness of the input image data.
Claims24
A control device of a projection system including an optical system that projects an image generated in a display portion based on input image data to a projection object, and an imaging portion that images the projection object, the control device comprising:
- a distance determination portion that acquires first captured image data of the image projected to the projection object from the imaging portion and determines a distance from an object present between the projection object and the optical system to the optical system based on a first sharpness of a part or an entire part of the first captured image data and a second sharpness of the input image data.
A control method of a projection system including an optical system that projects an image generated in a display portion based on input image data to a projection object, and an imaging portion that images the projection object, the control method comprising:
- a distance determination step of acquiring first captured image data of the image projected to the projection object from the imaging portion and determining a distance from an object present between the projection object and the optical system to the optical system based on a first sharpness of a part or an entire part of the first captured image data and a second sharpness of the input image data.
A non-transitory computer readable medium storing a control program of a projection system including an optical system that projects an image generated in a display portion based on input image data to a projection object, and an imaging portion that images the projection object, the control program causing a computer to execute:
- a distance determination step of acquiring first captured image data of the image projected to the projection object from the imaging portion and determining a distance from an object present between the projection object and the optical system to the optical system based on a first sharpness of a part or an entire part of the first captured image data and a second sharpness of the input image data.
