Patent ID: 7855731

Claim:
An image vibration-compensating apparatus, applicable to an image-capturing apparatus to compensate a captured image, the image vibration-compensating apparatus comprising: an adaptive edge extractor, for receiving an image signal of the image and calculating an edge feature value of each pixel in the image signal and outputting an edge feature signal, wherein an edge feature frame constituted by the edge feature signal has multiple sub-regions; a sub-region movement detector, electrically connected to the adaptive edge extractor, for searching a sub-region in a previous edge feature frame similar to each sub-region of a current edge feature frame respectively, and outputting a plurality of first motion vectors; a frame motion calculator, electrically connected to the sub-region movement detector, for calculating a second motion vector of the current image corresponding to the previous image according to the first motion vectors, wherein the frame motion calculator outputs the one with the highest correlation value among the first motion vectors as the second motion vector; and a correcting vector generator, electrically connected to the frame motion calculator, for accumulating the second motion vector in a predetermined period and outputting a correcting motion vector; wherein, the image-capturing apparatus compensates the image according to the correcting motion vector.
