Embodiment Construction

[0033] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] figure 1 is a block diagram of a behind-the-scenes buffer management device according to an exemplary embodiment of the present invention.

[0035] refer to figure 1 , the behind-the-scenes buffer management device 100 includes an application unit 110 , a request unit 120 , a response unit 130 , a main memory 140 , a Java Virtual Machine (JVM) 150 , and a video control unit 160 . The behind-the-scenes buffer management device 100 of the present invention is a part of an instrument connected with a display device that outputs an image, and thus creates a GUI-like screen.

[0036] The application unit 110 creates a GUI to be displayed on a display device using a programming language, draws the created GUI, and requests to hide or delete a previously created GUI. The GUI mainly consists of a window frame and an image displayed in the window. In the f...

Abstract

An off-screen buffering management device and method are disclosed. In the device, an application unit (110) creates a window to be displayed on a screen, and makes a request for a drawing of the created window. An off-screen buffering area for storing off-screen data corresponding to the window is set in a back buffer (163), and a buffer manager (152) draws the window, if a request for drawing the window is made, in the set off-screen buffering area in the back buffer and stores the window.

Description

technical field [0001] The present invention relates to a behind-the-scenes buffer management device and method, in particular to setting an area for displaying the behind-the-scenes data of the window on the back buffer, so that the number of copies of the behind-the-scenes data generated before the window is drawn in the back buffer can be reduced and the buffering speed can be improved Buffer management apparatus and methods. Background technique [0002] Due to the increasing demand for multimedia-related functions in recent years, off-screen buffering management devices (off-screen buffering management devices) that provide images using Java applications are now being developed. In the case of using a Java application, the behind-the-scenes buffer management device provides a Graphical User Interface (GUI) created by the Java application to the display device. [0003] Generally speaking, a GUI is expressed by a window frame. Therefore, in the case of drawing on a dis...
