Abstract
A video stabilization method includes: measuring an inter-frame camera motion based on a difference angle of a relative camera view direction in comparison with a reference camera view direction in each frame of a frame sequence of a video; generating a camera motion path of the frame sequence by using the inter-frame camera motion and determining a camera view direction adjustment angle based on a user's view direction by using the camera motion path; and compensating for the camera view direction by using the camera view direction adjustment angle in each frame.
