Abstract: A control device for controlling a shape of a projection image projected by a projector. The control device communicates with the projector. A correction target point of the projection image is selected, and an image including an image indicative of the selected correction target point and a first pattern associated with the correction target point is displayed on a display section. A user's operation for moving the target point of the projection image is received. According to selection of the target point of the projection image, a first instruction for projecting a second pattern corresponding to the first pattern is transmitted to the projector, and a second instruction for moving the target point of the projection image according to the received user's operation is transmitted to the projector.

Abstract: A projection control apparatus that controls projection using a plurality of projection devices that project optical images onto a projection plane. The projection control apparatus obtains a projected area of each of the plurality of projection devices on the basis of an image obtained by capturing the projection plane. The projection control apparatus then executes a first adjustment process of adjusting the projected area of each projection device so as to cause the projected areas of other projection devices, among the plurality of projection devices, that are not a reference projection device, to correspond to the projected area of the reference projection device. The projection control apparatus cancels geometric correction applied in the other projection devices before starting the first adjustment process and does not cancel geometric correction applied in the reference projection device before starting the first adjustment process.

Abstract: A control apparatus that controls a projection area of each of projection devices is provided. The control apparatus notifies relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.

Abstract: A control apparatus controls a plurality of projection apparatuses performing stack projection or multiple projection, and includes a reception unit configured to receive an instruction from a user to change a stack projection area or a multiple projection area of the plurality of projection apparatuses, and a control unit configured to control a first projection apparatus and a second projection apparatus of the plurality of projection apparatuses in a different manner in a case where the stack projection area or the multiple projection area exceeds a projection area of the first projection apparatus and does not exceed a projection area of the second projection apparatus when the stack projection area or the multiple projection area is changed based on the instruction.
