Embodiment Construction

[0012] The image processing method provided by the present invention can enable or disable the image capture function of a specified graphics card or a specified surface through the application layer interface, and can also set the area range of the captured image through the interface. At the same time, the present invention is not only suitable for supporting Single graphics card single output or multi-output situation is also applicable to multi-graphics card / multiple situations. The present invention first constructs the screen capture shell (S101), and then realizes the image processing process through the screen capture shell: firstly, it is necessary to replace the system display driver DLL file and the system graphics driver interface (DDI) defined in the file with the pre-constructed screen capture The DLL file (S102) of the shell and the graphics driver interface (DDI) (S104) defined in the screen capture shell; obtain the relevant parameters (S105) of the system surf...

Abstract

The invention provides a method for image processing with the following steps of replacing a DLL file of a system video driver and a delineation driver interface (DDI) defined in the file with the pre-structured DLL file of a screen-grasping shell and a delineation driver interface (DDI) defined in the screen-grasping shell, obtaining the corresponding parameters of the system surface and setting a user-defined mapping surface according to the corresponding parameters of the system surface in the screen-grasping shell, and image-mapping on the user-defined mapping surface via system invoking the DLL of the screen-grasping shell. The invention can ensure the good running of graphics cards and the speed-up running of DirectX, avoid the conflicts to the speed-up running of DirectX; and improve the processing efficiency of grasping continuous images as a result of realizing screen-grasping on the display driving hardware layer.

Description

technical field [0001] The invention relates to a method for image data processing. Background technique [0002] With the application and development of computer technology, users often wish to capture images on the computer screen, especially to continuously capture and process the images. In order to meet the needs of users, the corresponding image capture technology came into being. Currently commonly used technologies for continuously capturing images include the Mirror Driver technology developed by Microsoft Corporation, the timer technology and the message hook technology. However, when using the MirrorDriver technology, it is easy to cause conflicts with the graphics card’s DirectX acceleration, and the timer technology and message hook technology need to exchange data at the application layer, so it consumes a lot of computer CPU resources and may seriously affect the normal operation of the machine. Contents of the invention [0003] The invention provides an ...
