There is provided an image processing device, an image projection device, a control device, an information processing device, an image projection system, an image processing method, and a program that make it possible to suppress a reduction in a subjective image quality. On the basis of each frame image of a moving image, a time during which a projection image of each frame image of the moving image is viewable by a user is controlled. For example, a controller controls the time during which the projection image is viewable by the user, to cause a difference between the moving image and the projection image due to a reduction in a luminance and a difference between the moving image and the projection image, which increases due to an increase in the time during which the projection image is viewable by the user, to be suppressed.
