Abstract
A projector that is capable of correcting optical characteristics without degrading gradation of a projected image. The projector includes a projection optical system for projecting a projected image on a projection plane. When performing projection based on RAW data obtained through image pickup, the RAW data is corrected based on correction parameters and developed, whereby image data is generated. A projected image corresponding to the image data is projected on the projection plane.
