Screen printing method

Abstract

This invention discloses a screen catching method, which first sets a buffer area for screen in the catching system with its frame number determined by the screen images number played per second. The method also comprises the following steps: a, the system orderly playing the screen images and the system buffer area adopting new means to orderly memory the compressed screen images; b, the system requiring the prior buffered images form the area when executing the catching orders and using the image as the image to be caught for buffer.

Description

technical field [0001] The invention relates to a screen image processing technology, in particular to a screen capture method. Background technique [0002] When utilizing television (TV) or computer to watch continuous picture, the user often can remember deeply some wonderful scenes in this continuous picture, comment on. However, some highlights in the continuous picture played by TV or computer are fleeting, especially when the continuous picture is some high-speed moving objects, such as: football match, sprint race and so on. How to preserve these wonderful shots so that users can watch and recall these wonderful shots later becomes a problem. [0003] At present, the method to solve this problem is to capture the screen of the screen that plays the continuous picture: the system that uses the screen to play the continuous picture has an embedded screen capture function, when the system that should use the screen to play the continuous picture receives the screen cap...

[0004] However, there is an obvious shortcoming in the above method: time lag, that is, after the user watches the desired screen from the screen, and then sends a screen capture command to capture the screen, such as playing a continuous The screen system sends the command to capture the screen. Since the screen is played continuously, the current screen captured by the system that receives the command and uses the screen to play the continuous screen is not the screen that the user wants to capture, but the screen that the user wants to capture. It is expected that the captured screen image lags behind the screen image, thus causing a time lag in capturing the screen image

This may not be a big problem for slow-changing continuous screens. However, for most continuous screens, especially fast-changing continuous screens, "time lag" will cause the captured screens to be different from the screens that the user expects to capture. inconsistencies
