METHOD FOR IMPLEMENTING SYNCHRONOUS RISING, FALLING, OR TRANSLATION OF PROJECTION IMAGE ALONG WITH ROLLABLE SCREEN

A method for implementing a synchronous rising, falling, or translation of a projection image along with the movement of a rollable screen is provided. After a system is powered on and started, a projection screen first reports a current position of a screen to a project host via a communication link. The projection host performs a preprocessing on a projection image according to the current screen position n0 obtained from the projection screen and an image is projected onto the projection screen. The projection host informs the projection screen via the communication link and confirms that the current projection image is aligned according to the current position of the projection screen. After the projection screen obtains confirmation information from the projection host, the projection screen is driven to reach the next position, and the projection host obtains the next specific position of the projection screen via the communication link.
