发明名称 Projector that performs image calibration utilizing first and second wavelength bands
摘要 A projector includes: an imaging unit that picks up an image of a projection target area with light in a first wavelength band and generates a first pickup image and picks up an image of the projection target area with light in a second wavelength band and generates a second pickup image; an image generating unit that performs keystone distortion correction on the basis of the first pickup image; a positional-information generating unit that generates, on the basis of the second pickup image, positional information indicating a position of indication light included in the projection target area; and a projecting unit that projects an image based on the positional information in a state in which the keystone distortion correction is performed.
