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 9):
The projection system according to  claim 8 , wherein if a value of the focal length evaluation function of a projected image corresponding to a starting position of a first moving of the optical engine is smaller than a value of the focal length evaluation function of a projected image corresponding to an end position of the first moving, then the controller controls the optical engine to continue moving the pre-set step length towards a same direction until a value of the focal length evaluation function of a projected image corresponding to a starting position of a certain moving is greater than a value of the focal length evaluation function of a projected image corresponding to an end position of the certain moving, and the starting position of the certain moving is determined as a position where the optical engine stands to get the projected image clearest,\n if the value of the focal length evaluation function of the projected image corresponding to the starting position of the first moving of the optical engine is greater than the value of the focal length evaluation function of the projected image corresponding to the end position of the first moving, then the controller controls the optical engine to move the pre-set step length towards an opposite direction, until a value of the focal length evaluation function of a projected image corresponding to a starting position of a moving is greater than a value of the focal length evaluation function of a projected image corresponding to an end position of the moving, and the starting position of the moving is determined as a position where the optical engine stands to get the projected image clearest.
