20090051777 | APPARATUS AND METHOD FOR ESTIMATING MOTION DUE TO HAND TREMBLING AND IMAGE PICKUP DEVICE USING THE SAME - A motion estimation apparatus and method for estimating a global motion vector of an image due to hand trembling by using zoom information and focus information are provided. The motion estimation method includes: dividing a photographed image into a plurality of image blocks; determining a weight value for a motion vector of each of a plurality of image blocks based on focus information and zoom magnification information; predicting a motion vector for each image block; and estimating a global motion by applying the weight value determined for the motion vector for each image block to the predicted motion vector. | 02-26-2009 |
20090091631 | METHOD AND APPARATUS FOR STABLY CORRECTING HANDSHAKE IN CAMERA PANNING SITUATION - Provided are an apparatus and method for stably correcting handshake that occurs during a camera panning situation. In the method, movement information is accumulated by a predetermined unit for a predetermined period of time. A regression model is matched to the accumulated movement information so as to determine a situation as one of a panning mode and a handshake mode. Switching is performed between the handshake mode and the panning mode according to the size of a matching factor generated by the matched regression model. Handshake is corrected on the basis of a handshake correcting amount determined according to one of the handshake mode and the panning mode. | 04-09-2009 |
