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 16):
The projection system according to  claim 6 , wherein the description information includes a focal length evaluation function based on a gray level difference, wherein the focal length evaluation function is expressed as: F \ue8a0 ( i ) = \u2211 ( x , y ) \ue89e { \uf603 f i \ue8a0 ( x , y ) - f i \ue8a0 ( x , y - 1 ) \uf604 + \uf603 f i \ue8a0 ( x , y ) - f i \ue8a0 ( x - 1 , y ) \uf604 } wherein, F(i) represents the focal length evaluation function, (x, y), (x, y\u22121) and (x\u22121, y) are coordinates of pixel points of the image; \u0192(x, y), \u0192(x, y\u22121) and \u0192(x\u22121, y) are gray levels of the pixel points of the image collected by the photosensitive detector, and i is a number for a frame of image.
