    • A video image stabilization system includes a camera having an image capturing device capturing a video image. The camera has a selectively adjustable field of view. A processing device is operably coupled to the camera. The processing device receives signals indicative of the field of view of the camera and images captured by the camera. The processing device automatically tracks movements of at least one object in the images. The processing device determines a stabilizing adjustment for the video image as a function of an unintended change in the field of view of the camera during a time interval between capture of a first image and capture of a second image. The determining is based upon the signals indicative of the field of view and an analysis of the first and second images.
    • 视频图像稳定系统包括具有拍摄视频图像的图像捕获装置的相机。 相机具有可选择的可调视野。 处理装置可操作地耦合到照相机。 处理装置接收指示照相机的视野的信号和由照相机拍摄的图像。 处理装置自动跟踪图像中的至少一个对象的移动。 处理装置根据拍摄第一图像和捕获第二图像之间的时间间隔期间的相机视场中的意外变化来确定视频图像的稳定调整。 该确定基于指示视场的信号和第一和第二图像的分析。
