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.

Control device for correcting projection image, projection system, method of controlling same, and storage medium

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.
