摘要：
According to the present invention, a real-time image stabilization method for imaging system including an image sensor, and a motion sensor capable of generating pitch information and yaw information comprising angle values comprises the steps of: segmenting the entire area of an image into a quadrant and previously setting four or more unit search areas including at least one of the quadrant; receiving an image from the image sensor in every frame; receiving, from the motion sensor, a motion sensor signal including at least pitch information and yaw information in every frame; selecting one of four or more unit search areas as a reduced search area, based on unit motion vector consisting of the vertical components of the pitch information and the horizontal components of the yaw information, in every frame; operating motion vector in the selected reduced search area with respect to an image of a current frame and an image of a previous frame, in every frame; and displacing the image of the current frame in a reverse direction of the motion vector operated in every frame to create an image for which the motion of a camera is compensated.
