Abstract :
An image frame of an interlaced camera is composed of two sub frames (half-frames or fields). If the camera moves when it captures video images, two sub frames become misaligned and this lowers the image quality. In this paper, a new algorithm that removes this undesired effect from such misalignment is presented.
