Problems solved by technology

However, in the current existing design schemes, when the screen is rolled up or unfolded, the projected image cannot strictly follow the screen to move synchronously, the user experience is not good, and it also greatly limits the usage scenarios of this type of projection system. Therefore, , an improved technology is urgently needed to solve this problem existing in the prior art

Abstract

The invention discloses a method for realizing synchronous lifting or synchronous translation of a projection picture along with a rollable screen. The method comprises the steps that after a system is powered on and started, a projection screen reports the current position of the screen to a projection host through a communication link; the projection host obtains a current screen position n0 from the projection screen, preprocesses projected images; the projection host completes the preprocessing of a projection image, and projects the image onto a projection screen; the projection host informs the projection screen through the communication link, and determines that the current projection image is aligned according to the current position of the projection screen; the projection screenobtains confirmation information of the projection host. According to the method provided by the invention, the projection host and the projection screen can be designed into a real linkage system, the perfect matching of a projection picture and the projection screen is realized, and an optimal display effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of synchronous lifting or synchronous translation of a projection picture following a rollable screen, in particular to a method for realizing synchronous lifting or synchronous translation of a projection picture following a rollable screen. Background technique [0002] Under normal circumstances, there is no connection between the traditional projector and the emerging projection TV (hereinafter referred to as: projection host) and the screen displaying projected images (hereinafter referred to as: projection screen). projection display system. That is, the curling or unfolding of the projection screen is not controlled by the projection host; when the projection host is turned off or turned on, the projection screen will not perform the curling or unfolding action accordingly. In some specific cases, projection system suppliers or projection system users will develop some simple "projection host...
