Abstract:
A projection control apparatus includes an acquisition unit configured to acquire a captured image of a projection plane on which a first image is projected by a projection unit, a specification unit configured to specify an image projection area of the projection unit within the captured image acquired by the acquisition unit, an association unit configured to, in the captured image of the projection plane on which a second image different from the first image is projected by the projection unit, associate coordinates on the image projection area specified by the specification unit with coordinates managed by the projection unit, and a control unit configured to calculate distortion correction parameter for the projection unit by using an association result of the between the coordinates by the association unit. The projection control apparatus can reduce the time for adjustment of a projection image shape.

Claim (Index 3):
The projection control apparatus according to  claim 2 , wherein, in a case where the determination unit determines that the gradation of the first image is to be changed, the second control unit changes the gradation of the first image, causes the projection unit to project the changed first image, acquires a captured image of a projection plane on which the changed first image is projected, and determines whether the gradation of the changed first image is to be further changed.
