1. A control apparatus that controls a projection area of each of projection devices, comprising:
- a controller configured to;
control the projection area of each of the projection devices;
determine whether a temperature variation of each of the projection devices is greater than or equal to a threshold value based on an elapsed time period from when a light source of each of the projection devices starts up; and
perform notification relating to control of the projection areas, in a case where the temperature variation of at least one projection device, among the projection devices, is greater than or equal to the threshold value,wherein the controller performs the notification by causing a message to be displayed on a display device.

10. A projection device for projecting an image onto a projection area, comprising:
-
a controller configured to; control a shape or a position of the projection area; determine whether a temperature variation of the projection device is less than a threshold value based on an elapsed time period from when a light source of each of the projection devices starts up; and perform predetermined notification relating to control of the projection area, in a case where the controller determines that the temperature variation of the projection device is not less than the threshold value, wherein the controller performs the predetermined notification by sending a message to a control apparatus of the projection device.
