PROJECTOR, METHOD OF CONTROLLING PROJECTOR, AND PROGRAM THEREOF

摘要

A projector captures an image of a projection target, on which a projection image is projected, and corrects the projection image by using the captured image. The projector includes a projection unit that projects the projection image onto the projection target; a capture unit that captures an image of a projected region including the projection target; a calculation unit that calculates three-dimensional data regarding the projected region, and calculates a correction parameter, including a distortion parameter and a motion parameter, using the calculated three-dimensional data; and a correction unit that corrects the projection image using the correction parameter. The correction unit performs a first correction corresponding to a shape of the projection target using the distortion parameter, and performs a second correction corresponding to at least one of a movement of the projection unit and a movement of the projection target.

1. A projector, which captures an image of a projection target, a projection image being projected onto the projection target, and corrects the projection image by using the captured image, the projector comprising:
a projection unit that projects the projection image onto the projection target; a capture unit that captures an image of a projected region including the projection target; a calculation unit that calculates three-dimensional data regarding the projected region, and calculates a correction parameter using the calculated three-dimensional data; and a correction unit that corrects the projection image using the correction parameter calculated by the calculation unit, wherein the calculation unit calculates a distortion parameter and a motion parameter, as the correction parameter, based on the captured image, and the correction unit performs a first correction corresponding to a shape of the projection target using the distortion parameter, and performs a second correction corresponding to at least one of a movement of the projection unit and a movement of the projection target.
