Abstract

Proposed is a digital cinema projection method including the steps of: a digital cinema projector projecting an image to a screen and an image acquisition unit acquiring the image on the screen; an image analysis unit performing digital analysis on the acquired image to obtain a plurality of index parameters of the acquired image; according to each of the index parameters performing correction processing on an image signal input from a digital cinema server and outputting same to the digital cinema projector; and the digital cinema projector projecting the corrected image. Also provided is a digital cinema optimization device comprising an image acquisition unit an image analysis unit and an image processing unit. Also provided is a digital cinema projection system comprising a digital cinema optimization device a digital cinema server and a digital cinema projector. The digital cinema optimization device is electrically connected between the digital cinema server and the digital cinema projector. The method device and system of the present invention effectively improve the quality of a projected image.
