APPARATUS AND METHOD OF ESTIMATING DISPLACEMENT DUE TO ARM SHAKE AND DEVICE USING SAID METHOD AND APPARATUS TO OBTAIN IMAGES Russian patent published in 2011 - IPC H04N7/32 G06T7/20 H04N5/232 

FIELD: information technology.

SUBSTANCE: invention discloses apparatus for estimating displacement and a method of estimating the common displacement vector of an image due to arm shake by using scaling information and focus information, involving the following steps: the captured image is divided into multiple image blocks; a step for determining the weight coefficient value for the displacement vector of each of the multiple image blocks based on focus information and magnification information; a step for predicting the displacement vector for each image block; and a step for estimating overall displacement by applying the weight coefficient value defined for the displacement vector for each image block to the predicted displacement vector.

EFFECT: high accuracy of estimating displacement due to arm shake.
