Abstract
A projector includes: an image capturing unit that captures an image of a projection target image (an original image or a corrected image) projected by the projector on a projection surface; a shape model hold unit that holds shape models; a model selection unit that selects a projection surface shape model based on correspondence relationships between first feature points on the projection target image and second feature points on the captured image; a parameter calculation unit that calculates a model parameter which is to be used to approximate a shape of the projection surface shape model to the shape of the projection surface and indicates a positional relationship between the projection surface and the projector, for each projection target image based on the correspondence relationships; a correction unit that corrects another original image; and a projection unit that projects the corrected image as another projection target image.
