Abstract

The disclosed method for acquiring video data comprises: AP sends trigger signal for video data to the video drive module; the latter acquires video data by set video sensor and returns data to AP. This invention can obtain video data with multiple angles and resolution.

Description

technical field [0001] The invention relates to image transmission technology, in particular to a method and system for acquiring video data. Background technique [0002] With the development of network technology, more and more users use camera devices for video chatting. Current camera devices, such as a personal camera (PC Camera), all have a digital signal processor (DSP) corresponding to an image sensor (Sensor). The process of obtaining video data mainly includes: first, the user utilizes an application program to send a video to the video driver module Request, requires to obtain video data; then, the video driver module triggers the DSP in the PC Camera, and the DSP utilizes the only Sensor in the PC Camera to capture video data, and sends the video data to the video driver module; at last, the video driver module Return this video data to the application. [0003] In the existing method for obtaining video data, since one DSP in the camera device only corresponds...
