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. A projection apparatus includes at least one processor and an acceleration sensor which detects an inclination of the projection apparatus, in which the processor performs the processes of acquiring a difference between i) a first detection value which is detected by the acceleration sensor in a case where the projection apparatus is installed on an installation surface and ii) a second value which is detected by the acceleration sensor at a time which comes after the installation of the projection apparatus with the projection apparatus on the installation surface, and in a case where the difference becomes more than a threshold value, controlling to notify a warning at a predetermined timing by functioning as a notification unit or to stop functions of the projection apparatus.

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. In addition, in a case where the adjustment degree reaches the predetermined threshold value, the projected image processing unit gives a warning to the user at a predetermined timing as a notification control unit.-

Abstract: In an image processing apparatus, a characteristic acquisition unit acquires a characteristic of the projection object. A correction control unit determines a parameter in accordance with the characteristic and corrects an input image based on the parameter. A characteristic specifying unit specifies an attentional characteristic region based on the characteristic. A captured image acquisition unit acquires a captured image of a projection image. A change determination unit determines whether the attentional characteristic region changes by a predetermined amount or more from the input image and the captured image, causes the characteristic acquisition unit to acquire the characteristic if it is determined that the region changes, and redetermines to cause the correction control unit to produce a projection image.
