Method for realizing displaying of high dynamic luminance range images by a plurality of projecting cameras

Abstract

The invention discloses a method for realizing the displaying of high dynamic luminance range images by a plurality of projecting cameras. The method comprises the following steps: firstly, the position, the projecting angle and the display size of each projecting camera is adjusted to ensure that the projection display regions of all the projecting cameras on a screen have an overlap region; secondly, all sub controllers synchronistically receive high dynamic luminance range images, conducting coordinate conversion and color conversion on each pixel of the received images, and then synchronistically transmitting the processed images to the controlled projecting cameras; thirdly, a main controller is used for controlling all the sub controllers to synchronously receive the high dynamic luminance range images, and synchronously transmit the processed images to the controlled projecting cameras. The method has the advantages that the projecting lumen and the projecting luminance contrastcan be improved, the black level can be better shown, and HDR images can be displayed by projecting, namely, the color value which exceeds the common range (0 to 255) can be displayed by projecting so as to ensure that the projecting image is full of sense of reality on the aspects of deepness, detail and color and the like.

Description

A method for displaying high dynamic brightness range images with multiple projectors technical field The invention relates to a method for displaying high dynamic brightness range images, in particular to a method for realizing the display of high dynamic brightness range images by using multiple projectors. Background technique Projectors have developed into three series since their inception: Liquid Crystal Display (LCD) projectors, Digital Light Processing (Digital Lighting Process, DLP) projectors, and cathode ray tube (CathodeRayTube, CRT) projectors. These projectors not only take on the important task of continuing to improve the projection lumens and brightness contrast, but also cannot project and display high dynamic brightness range images. A high dynamic brightness range image is an HDR image, and HDR is an abbreviation of High-Dynamic Range. Contents of the invention The object of the present invention is to solve the deficiency of the prior art, that is,...
