Abstract
A projector includes a manipulation detecting unit that performs a manipulation detecting process on the basis of captured image data of an imaging unit, and a correction control unit that performs a distortion correcting process on the basis of the captured image data. An imaging control unit sets an image-capturing resolution of the imaging unit to resolutions different from each other between a case where the manipulation detecting unit performs the manipulation detection process and a case where the correction control unit performs the distortion correcting process.
Claims6
A projector, comprising:
- an imaging unit which captures an image of a projection surface;
- a first processing unit which detects a manipulation performed on the projection surface on a basis of an image-capturing result of the imaging unit, and performs a first process corresponding to the manipulation that is detected;
- a second processing unit which performs a second process different from the first process on the basis of the image-capturing result of the imaging unit;
- and
- a control unit which sets an image-capturing resolution of the imaging unit to resolutions different from each other between a case where the first processing unit performs the first process, and a case where the second processing unit performs the second process, the image-capturing resolution being a number of pixels used to capture an image,
- wherein the second process that is performed by the second processing unit includes a process of correcting distortion of a projection image that is projected onto the projection surface,
- wherein the first process that is performed by the first processing unit includes a determination process of determining whether or not an indication manipulation detected in a detection process corresponds to a manipulation that is set in advance, and
- the control unit sets the image-capturing resolution of the imaging unit in a case where the first processing unit performs the first process at a resolution lower than a resolution in a case where the second processing unit performs the second process.
A method of controlling a projector, comprising:
- controlling a projector including an imaging unit that captures an image of a projection surface;
- and
- setting an image-capturing resolution of the imaging unit to resolutions that are different from each other between a case of detecting a manipulation performed on the projection surface on a basis of an image-capturing result of the imaging unit and performing a first process corresponding to the manipulation that is detected, and a case of performing a second process different from the first process on the basis of the image-capturing result of the imaging unit, the image-capturing resolution being a number of pixels used to capture an image,
- wherein the second process that is performed includes a process of correcting distortion of a projection image that is projected onto the projection surface,
- wherein the first process includes a determination process of determining whether or not an indication manipulation detected in a detection process corresponds to a manipulation that is set in advance, and
- setting the image-capturing resolution of the imaging unit in a case where the first process is performed at a resolution lower than a resolution at which the second process is performed.
