Problems solved by technology

However, the current general-purpose scaling processing algorithm needs to perform interpolation operations on adjacent pixels. When performing boundary processing on the above-mentioned parts of the image, it is often impossible to obtain redundant boundary pixel information, resulting in gaps in the middle of the stitched image.

Abstract

The embodiment of the invention provides a video processing method, a video processing device and a video processing system. The video processing method comprises the following steps: receiving multiple video sources; respectively storing the multiple video sources to specified positions of a memory according to respective corresponding image parameters to finish image splicing, thereby obtaininga spliced image; reading the spliced image from the memory; and performing image processing on the spliced image to obtain a target image. The video processing method provided by the embodiment of theinvention can solve the problem that a gap appears in the middle of the spliced image output by the video processor.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, a video processing device and a video processing system. Background technique [0002] Video processing equipment often has multiple video input interfaces. Based on the current application market, the DVI interface occupies most of the input interfaces of video processing equipment, and it is also an indispensable functional interface in customer applications. Existing video processing devices usually perform independent scaling processing on multiple video sources to obtain corresponding processed video sources, and then perform splicing processing on the multiple processed video sources to obtain a whole spliced ​​image output. Such as figure 1 As shown, the video processing device independently scales the video source received by each interface to obtain the processed output upper left, output upper right, output lower left, and ou...
