Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] The purpose of the embodiments of the present invention is to propose a multi-zoom channel display system. Compared with the prior art, the system design using this architecture can solve the stability of the system work and reduce the consumption of hardware resources, as well as more flexible Expand the seamless splicing of multiple display screens to display enlarged and reduced images, which greatly enhances the system's processing ability and scope of ap...

Abstract

The embodiment of the invention discloses a video processor. The video processor is provided with a plurality of zooming devices to perform image zooming processing on an input source image so as to generate a plurality of zoomed images, and the zoomed images are provided to perform multi-image display. In addition, the embodiment of the invention further discloses a display system and a video image processing method of the video processor. The multi-channel zooming processing scheme of the embodiment of the invention can reduce the system running clock rates of the zooming devices, and make the system work stably in a video clock cycle.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video processor, a display system with image scaling function and a video image processing method. Background technique [0002] Scaler (scaler) is a scaling engine widely used in display systems. Scaling is actually to change the horizontal and vertical resolution of the image, so that the video content is suitable for the resolution of the display screen and can be displayed normally and completely. [0003] At present, the existing technology is to perform single-channel scaling on the same source image through a scaler, and then display the scaled image on the target display screen; for example figure 1 In the single scaling channel display system shown, the enlarged image through a scaler is sent to three independently controlled 1080P resolution display screens for multi-screen splicing display. However, the system operating clock rate of the scaler is the video...
