Abstract: The present invention aims to make it possible to detect deterioration of a housing of a projection apparatus and to notify a user of the deterioration of the housing. The projection apparatus includes a projected image processing unit which registers a deformation parameter as an initial value in a case where the deformation parameter for a projected image is set as an initial setting to be made at the time of installation of the projection apparatus as a registration control unit. In a case where the deformation parameter for the projected image is adjusted by a user operation after the initial setting is made, the projected image processing unit decides whether an adjustment degree that the deformation parameter is adjusted from the initial value reaches a predetermined threshold value as a decision unit.
