Abstract
A method of geometric correction can be designated by an intuitive and simple operation, with respect to a projected image projected by a projector. The projector includes a projection unit that projects an image on a projection target, and a correction unit that performs the geometric correction of a projected image projected by the projection unit, based on a deformation amount in a predetermined direction and deviation of the deformation amount in the predetermined direction with respect to the projection target.
