Title:
PROJECTION SYSTEM, CONTROL DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/084951
Kind Code:
A1
Abstract:
The present disclosure pertains to a projection system, a control device, and a control method with which it is possible to effectively suppress the vibration occurring to videos. The present disclosure analyzes a first acceleration signal outputted from a first acceleration sensor that is provided to the bottom of a vehicle, predicts vibrations occurring to a screen and a projector device that are secured to the ceiling of the vehicle, and establishes a predictive correction value based on the prediction, as well as establishing a correction value based on measured values in accordance with the relative behaviors of the screen and the projector device. Then, the correction value is fed back to the predictive correction value and control computing is performed, whereby the drive amount of an actuator for suppressing the vibration of a video projected to the screen is established. The present technology can be applied to, for example, a projection system that is mounted in a vehicle.
