Characterizing point checking region setting apparatus and method, and image stabilizing apparatus including the same

摘要

Provided is an image stabilizing apparatus and method for correcting an image that is shaken due to a movement of a camera. The image stabilizing apparatus includes a characterizing point checking region setting unit including: a sample frame extract unit which extracts a plurality of image frames obtained for a certain period of time in image data obtained by photographing an object; and a frame analyzing unit which detects a plurality of characterizing points in the extracted plurality of image frames, and sets a characterizing point checking region which is used to check characterizing points in a currently input image frame.

1. A characterizing point checking region setting unit comprising:
a sample frame extract unit which extracts a plurality of image frames, obtained for a certain period of time, from image data obtained by photographing an object; and a frame analyzing unit which detects a plurality of characterizing points in the extracted plurality of image frames, and sets a characterizing point checking region, which is used to check the detected characterizing points, in a currently input image frame, wherein the frame analyzing unit comprises: a characterizing point detector which receives the plurality of image frames from the sample frame extract unit, and detects the plurality of characterizing points in the plurality of image frames; a characterizing point classification unit which classifies the plurality of characterizing points into a plurality of clusters for each of the image frames; a center point detector which detects a centroid point of the characterizing points in the plurality of image frames; and a check region determination unit which sets the characterizing point checking region including a major cluster among the plurality of clusters based on the centroid point.
