Example Embodiment

[0029] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work also fall within the protection scope of the present disclosure.

[0030] As described above, in order to make a general playback device for playing a low-resolution video signal compatible with a high-resolution display screen that displays a high-resolution video signal, according to one aspect of the present disclosure, a video signal conversion method is proposed , Making it possible to synthesize multiple frames of low-resolution images of the video signal into one frame of high-resolution images, so that a playback device that plays low-r...

Abstract

The invention provides a video signal conversion method, a corresponding video signal conversion device and a display system including the video signal conversion device. Therefore, low-resolution video signals can be converted and spliced into high-resolution video signals, thereby displaying the high-resolution images formed by spliced low-resolution images on a ultra high definition television. The video signal conversion method comprises steps of parallel receiving multiple sub-frames formed via segmentation of low-resolution images of the video signals; performing image processing on each of the recieved sub-frames; and synthesizing the multiple sub-frames after the image processing into a high-resolution image and displaying the high-resolution image on the display device.

Description

technical field [0001] The present disclosure relates to the field of video display, in particular to a video signal conversion method, a corresponding video signal conversion device, and a display system including the video signal conversion device. Background technique [0002] With the rapid development of display technology, the resolution of display panels is getting higher and higher, so that ultra-high-definition display screens are gradually applied to various fields. In order to match this ultra-high-definition display, a playback device capable of playing ultra-high-definition video signals is required. However, the high cost of such playback devices capable of playing ultra-high-definition video signals currently makes it difficult to popularize ultra-high-definition display systems. [0003] On the other hand, in some application scenarios, such as billboards, public information display boards, conference bulletin boards, etc. that need to display electronic sig...
