Apparatus and method for compensating for camera vibration during video photography

摘要

An apparatus for compensating for the motion of an image due to vibrations of a camera during video photography. A first motion detecting part extracts first directional information for an entire image area and detects a first directional motion component over a designated time period. A second motion detecting part extracts and magnifies second directional information for a partial image area and detects a second directional motion component over the designated period. A difference value calculating part inputs the first directional motion component and the second directional motion component and calculates a directional difference value indicative of the absolute value of the difference between the first directional motion component and the second directional motion component multiplied by a reciprocal of a magnification ratio. A compensating part selects the first directional motion component multiplied by the magnification ratio to compensate for the vibration when the directional difference value is greater than one. The compensating part selects the second directional motion component to compensate for the vibration when the directional difference value is less than or equal to one. The motions due to hand shaking during video photography are therefore correctly and stably compensated for.
