1. A projection apparatus that projects an image by an optical system having at least one optical characteristic being variable, the projection apparatus comprising:
a processor configured to perform a control of regulating a movement of a projection region to which the image is projected, based on the at least one optical characteristic in the optical system,
wherein the optical system comprises at least one of: a zoom lens having a variable angle of view as the at least one optical characteristic; and a projection optical system in which a projection direction as the at least one optical characteristic is variable by a rotational movement of at least a part of the projection optical system, and
the movement of the projection region is a movement based on a user operation or a movement based on projection information of an object onto which the image is to be projected.
