Problems solved by technology

However, this method will obviously distort and distort the displayed picture, that is, figure 2 As shown, it is a schematic diagram of a widescreen TV receiving a traditional 4:3 video signal in full-screen mode
[0006] However, when viewing a picture with a video signal of 4:3, whether it is using the aforementioned letterbox mode with black borders on both sides or the deformation of the full-screen mode, the visual effect cannot satisfy most users.
With the popularity of wide-screen TVs, more and more users will encounter this problem. Therefore, it is very important to provide a technology to solve this visual discomfort.

Embodiment Construction

[0049] The basic principle of the present invention is to regenerate the picture to be displayed in the black border according to the content of the current original video signal picture, and achieve the effect of eliminating the black border when converting the display ratio of the video signal in the letterbox mode.

[0050] The following describes in detail in conjunction with the embodiments and the accompanying drawings.

[0051] This embodiment uses the method and system of the present invention to display a video signal with a 4:3 display specification on a display system with a 16:9 display screen.

[0052] The flow chart of the display method in this embodiment is as follows image 3 shown. First, the display system receives a video signal 11; then the system performs black border removal processing 12 on the video signal; and then transmits the processed video signal.

[0053] The display system in this embodiment includes a schematic diagram of the system architec...

Abstract

The invention discloses a processing method and a system of video picture black borders, enabling the picture of a video signal to be displayed on a display screen at a state of no deformation and black borders. The method regenerates picture necessarily displayed in the black borders according to the existing original video signal picture so as to achieve the effect of eliminating the black borders when the display ratio of the video signal is converted in a letter box mode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a technical method and system for processing black borders of video images when using letter box (letter box) mode to process or play video signals. Background technique [0002] At present, most of the new display systems have been designed with a widescreen image with an aspect ratio of 16:9 to show an effect similar to a movie screen. At the same time, it is also the golden ratio that is most in line with human vision. It has the best wide field of view and provides better viewing experience. Visual effects. [0003] Taking "TV" as the main medium for general family leisure and entertainment, it is the so-called widescreen TV. However, many video signals still belong to the traditional aspect ratio of 4:3. The aspect ratio is different, so the widescreen TV itself tends to use the following two ways to solve: [0004] (1) Letter box mode: This mode retains the original aspe...
