Therefore,, how to make the picture of web camera picked-up or video recording more targeted, reduce user's use cost, become the technical task that those skilled in the art need to be resolved hurrily in fact for the web camera user.

Summary of the invention

The object of the present invention is to provide a kind of web camera of based target detection technique,, reduce use cost to improve the use specific aim of web camera.

In order to achieve the above object, the web camera of based target detection technique provided by the invention, comprise a web camera body, it also comprises: be used for the multiple image that described web camera body is absorbed is carried out target detection respectively to judge whether described multiple image comprises the module of target detection of target; Be used for capturing out the candid photograph module of being transmitted after the picture frame that comprises target is handled for described web camera body from described multiple image according to the testing result of described module of target detection.

Preferable, described target behaviour face or individually defined thing; If described web camera body adopts the DSP algorithm, then described module of target detection merges in the described DSP algorithm.

In addition, the web camera of described based target detection technique also comprises: be used to store the memory module of goal-selling picture, described memory module is connected whether comprise goal-selling so that described module of target detection detects described multiple image with described module of target detection.

In sum, the web camera that the present invention is based on target detection technique can avoid transmitting some insignificant pictures by the detection of module of target detection to target, effectively improves the use specific aim of web camera, reduces user's use cost.
