Abstract:
1. A projector comprising: a projection section which projects a calibration image onto a projection target; a shape determination section which determines at least part of a shape of the projection target based on sensing information from a sensing section or operation information from an operation section; a correction target area setting section which sets a correction target area, the correction target area being an area along the shape determined by the shape determination section; an aspect ratio calculation section which calculates an aspect ratio of the correction target area; a determination section which determines whether or not the aspect ratio is appropriate based on a first criterion when the shape determination section has determined the shape of the entire projection target, and determines whether or not the aspect ratio is appropriate based on a second criterion which is stricter than the first criterion when the shape determination section has not determined the shape of the entire projection target; and an image generation section which generates an image having the shape of the correction target area on a projection panel when the aspect ratio is appropriate, and generates an image having a reference aspect ratio on the projection panel when the aspect ratio is inappropriate.
