One embodiment of the invention discloses an image processing apparatus including a feature point extractor that detects a plurality of feature points in a first image input from an image sensor; a first motion vector extractor that extracts local motion vectors of the plurality of feature points and select effective local motion vectors from among the local motion vectors by applying different algorithms according to zoom magnifications of the image sensor; a second motion vector extractor that extracts a global motion vector by using the selected effective local motion vectors; and an image stabilizer configured to correct shaking of the first image based on the global motion vector. 本发明的一实施例，公开一种影像处理装置，包括：特征点提取器，从由影像传感器输入的第一影像中检测多个特征点；第一运动矢量提取器，提取所述多个特征点的局部运动矢量，根据所述影像传感器的变焦倍率而在提取的所述局部运动矢量中选择有效局部运动矢量；第二运动矢量提取器，利用选择的所述有效局部运动矢量来提取全局运动矢量；以及影像稳定器，基于所述全局运动矢量而校正所述第一影像的抖动。
