Abstract

The invention discloses a system and a method for simultaneously utilizing one camera by a plurality of application programs. The computer system comprises a virtual camera component coupled in a camera; the virtual camera component comprises a video acquisition source filter, a virtual camera service center and a virtual camera setting tool; the video acquisition source filter and the virtual camera setting tool are both coupled in the virtual camera service center; the video acquisition source filter processes the video data from the camera and transmits processed data to a plurality of camera application programs; the virtual camera service center controls the video acquisition source filter and transmits the video data from the camera to the video acquisition source filter; and the virtual camera setting tool uses proper working parameters to configure the virtual camera service center. By using the virtual camera component, the method resolves the conflicts among a plurality of application programs, thus ensuring that a plurality of application programs can share one camera simultaneously.

Description

Technical field [0001] The present invention relates to a computer system, in particular to a computer system and method that supports multiple application programs to simultaneously use a camera. Background technique [0002] Cameras are widely used in multiple client applications, such as webcam recording programs, video conferencing tools, and instant messaging (Instant Messenger, IM) tools. [0003] Such as figure 1 As shown in the prior art, the system 100 includes a camera application module 102, a Windows driver model (WDM) acquisition filter 104, and a physical camera 110. The camera application module 102 includes a plurality of camera applications, for example, MSN MESSENGER 108A, YAHOOMESSENGER 108B, SKYPE 108C, and “360-degree WEB FACE” application (hereinafter referred to as FACE program) 114. Among them, the FACE program 114 in the camera application module 102 is a smart login and lock / unlock application developed by OMicro. [0004] The WDM acquisition filter 104 is...
