Abstract

The invention relates to a multisource image processing method and an analysis processor, wherein the method comprises the steps as follows: A, collecting photos of test images; B, determining an overlapped projection area; C, overlapping the images; and D, balancing image brightness. The method and the analysis processor can be used for adjusting the projection location of a multisource image and realizing the sub-pixel-level overlap and brightness balancing of the multisource image. The method and the analysis processor not only can realize the integral display of the whole image, but also can greatly improve the showing quality of the multisource image.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-light source image processing method and an analysis processor. Background technique [0002] In science and technology museums, museums, theme parks, movie theaters and digital home theaters and other applications, such as multi-light source giant screens, ring screens and dome screens, etc., multi-light source projection display is required. Due to the location of the projector, the working power of the projector, Influenced by factors such as screen bending and external light source interference, there are phenomena such as non-overlapping of multi-light source projection images, incomplete picture display, and uneven projection brightness. In terms of image overlap, existing multi-light source image enhancement methods keep one projected image unchanged and change the display content of other projectors to achieve image overlap of multiple projectors. In this way, i...
