Patent number: 10848672Abstract: Provided are an image stabilizing apparatus and method thereof. The image stabilizing apparatus performs image stabilization by using both an image sensor and a motion sensor. Image distortion and movement are stably corrected by using both the position of a feature point, which is extracted by the image sensor and image processing, and the movement position of the feature point, which is predicted by the motion sensor.Type: GrantFiled: September 17, 2018Date of Patent: November 24, 2020Assignee: HANWHA TECHWIN CO., LTD.Inventors: Yeongeol Ryu, Sangji Park, Hwalsuk Lee, Shimin Yin
