ABSTRACT:
A projector includes an image distortion sensing section which generates image distortion sensing information, an environmental influence sensing section which generates environmental influence sensing information, a projection area information generation section which generates projection area information, an image distortion correction section which corrects distortion of a projection image and generates correction information indicating the degree of correction, a display area information generation section which generates display area information indicating the display area of the projection image after distortion correction based on the projection area information and the correction information, an environmental influence reduction section which performs processing of reducing environmental influence, a projection section which projects the projection image, and a differential image generation section which generates a differential image.
