Abstract
The present disclosure relates to a projection system, a control device, and a control method capable of effectively suppressing vibration generated in an image. A first acceleration signal output from a first acceleration sensor provided at a bottom of a vehicle is analyzed, vibration to be generated in a screen and a projector device fixed to a ceiling of the vehicle is predicted, a predicted correction value based on the prediction is obtained, and a correction value based on actual measurements is obtained in accordance with relative behavior of the screen and the projector device. Control calculation is then performed by feeding back the correction value to the predicted correction value, and an amount of drive of an actuator for suppressing vibration of an image projected on the screen is obtained. The present technology can be applied to, for example, a projection system mounted on a vehicle.
