Abstract:
1. An image processing system comprising: a sensing section which senses an area including at least a part of a projection image projected onto a projection target area to generate sensing information; a projection area information generation section which generates projection area information indicating a position of the projection image in an imaging area in the sensing section based on the sensing information; a projection target area information generation section which generates projection target area information indicating a position of the projection target area in the imaging area based on the sensing information; a correction information generation section which generates correction information indicating a degree of correction for distortion of the projection image based on the projection area information and the projection target area information; a display area information generation section which generates display area information indicating display area of the projection image in the imaging area in the case that the distortion of the projection image is supposed to have been corrected based on the projection area information and the correction information; and an environmental influence reduction section which performs processing of reducing environmental influence caused by a difference between an ideal environment and an actual environment by using information inside the display area included in the sensing information based on the sensing information and the display area information.
