System and method for grabbing frames of graphical data

Abstract

A frame-grabbing system in accordance with an exemplary embodiment of the present invention comprises a frame buffer, a graphics adapter, video output interface and logic. The graphics adapter is configured to receive graphics commands from a graphics application and to render graphical data from the graphics commands to the frame buffer. The video output interface is configured to read the frame buffer and to transmit a video data signal based on graphical data stored in the frame buffer. The logic is configured to perform, in response to a frame grab request, a frame grab of an image frame based on the video data signal, the frame defined by the graphical data stored in the frame buffer. The logic is further configured to prevent, in response to the frame grab request, the graphics adapter from updating the frame buffer during the frame grab.
