Abstract:
A screen, a projection system and a focusing method are provided. The screen is used for presenting a projected image and it includes a screen body, a photosensitive detector and a processor. The photosensitive detector is on a projection surface of the screen body for collecting a gray level of the image presented on the screen body. The processor is for obtaining description information of the image according to the gray level of the image collected by the photosensitive detector, the description information of the image indicating definition of the projected image.

Claim (Index 13):
A focusing method for the projection system of  claim 6 , the focusing method comprising:\n projecting an image by the optical engine onto the screen body, collecting, by the photosensitive detector, a gray level of the image projected by the optical engine onto the screen body, obtaining the description information of the image by the processor based on the gray level of the image collected by the photosensitive detector; adjusting, by the controller, the distance between the light exit surface of the optical engine and the projection surface of the screen body according to the description information obtained by the processor, thereby adjusting the definition of the image presented on the screen body.
