How to directly transfer data from camera to D3D texture in hareware?

Question

hi,all

     If  the camera  data transfer to raw data, and then the raw data blt to D3D surface, it will waste time for copying data form system memory to graphic memory. Does it  have a way which the camera data can directly convert to D3D texture(ID3DTexture2D) in hareware? if it can ,it will be faster . Is it have a sample for this or  Does any one know how to do it?

Thank you for your help
