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: A monitoring system includes a monitoring apparatus and a monitoring-target apparatus connected therewith via a network. The monitoring apparatus includes an inquirer that inquires as to whether or not the monitoring-target apparatus is capable of obtaining a status thereof. The monitoring-target apparatus includes a responder that transmits, when the monitoring-target apparatus is in a first status in which the status is obtainable, a response to the inquiry. The monitoring apparatus further includes a receiver that receives the response to the inquiry, and a requester that requests, when the receiver receives the response, the monitoring-target apparatus transmitted the received response to obtain the status of the monitoring-target apparatus. The monitoring-target apparatus further includes a communication controller that does not respond to the inquiry and the monitoring-target apparatus is in a second status in which the status is not obtainable, and that maintains the local monitoring-target apparatus in the second status.

Abstract: A projection processing device comprises a processor control unit that acquires, in response to acceptance of input information, projection position information associated with the input information, and instructs a projector to emit light or project an image enabling a user to identify a position based on the acquired projection position information.
