I bought a microsoft HD 3000 webcam, it works fine with 720p 30FPS

but there is a strange problem with opencv running this camera, when i open it with opencv videocapture. camera gives me 640*480 resolution picture while in windows 10 camera application it gives 720p which is right

i don't know what is wrong here

problem is with webcam or opencv?? anybody has any idea
