    • The invention relates to a method and a device for determining a displacement (15) of images in an image sequence, in particular, to compensate for camera movement. A number of image areas (6, 7, 8) are available to determine the displacement (15), whereby each area has a predetermined position in the image and predetermined dimensions. The method consists in separating an image movement, preferably caused by a camera movement, from an additional movement which is superimposed on the image in the following steps: the probability that the movement will occur without an additional movement is determined at different positions in an image; the position and dimensions of each image area (6, 7, 8) are determined and defined in a fixed manner, based on the probability that the movement occurs without the additional movement within one of the image areas (6, 7, 8); preferably, at least one first image area (6, 7) from the multiple image areas (6, 7, 8) is used to determine the displacement (15).
    • 本发明涉及一种用于确定图像序列中的图像的位移(15),尤其是用于补偿相机移动的方法和设备。 多个图像区域(6,7,8)可用于确定位移(15),由此每个区域具有图像中的预定位置和预定尺寸。 该方法在于将以优选地由相机移动引起的图像移动与以下步骤叠加在图像上的附加移动分离:在图像中的不同位置处确定移动将发生而没有附加移动的概率 ; 基于在一个图像区域(6,7,8)内没有附加移动发生移动的概率,以固定的方式确定和定义每个图像区域(6,7,8)的位置和尺寸; 优选地,来自多个图像区域(6,7,8)的至少一个第一图像区域(6,7)被用于确定位移(15)。
