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.
Claims32
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 controller that acquires first captured image data of the image projected to the projection object from the imaging portion, and determines, 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, that a gesture to the projection object is being performed in a state where a difference or ratio between the first sharpness and the second sharpness is within a predetermined range having an upper limit and a lower limit, and that the gesture is not being performed in a state where the difference or ratio is outside the predetermined range, and changes the input image data in a case where the controller has determined that the gesture is being performed.
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 controlling step of acquiring first captured image data of the image projected to the projection object from the imaging portion, and determining, 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, that a gesture to the projection object is being performed in a state where a difference or ratio between the first sharpness and the second sharpness is within a predetermined range having an upper limit and a lower limit, and that the gesture is not being performed in a state where the difference or ratio is outside the predetermined range, and changing the input image data in a case where the determining has been made that the gesture is being performed.
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 controlling step of acquiring first captured image data of the image projected to the projection object from the imaging portion, and determining, 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, that a gesture to the projection object is being performed in a state where a difference or ratio between the first sharpness and the second sharpness is within a predetermined range having an upper limit and a lower limit, and that the gesture is not being performed in a state where the difference or ratio is outside the predetermined range, and changing the input image data in a case where the determining has been made that the gesture is being performed.
