Image processing device, photographing device, reproducing device, integrated circuit, and image processing method

Abstract

To provide an image processing device that calculates a parameter used for correcting large video jitter with high accuracy even when the accuracy of a sensor for measuring a movement of a photographing device is low. The image processing device includes: a constraint condition generating unit () that generates a constraint condition using sensor information such that a parameter value falls within a range; and a parameter calculating unit () that calculates the parameter according to the constraint condition. The constraint condition generating unit () has: a feature vector generating unit () that generates a feature vector showing features of the sensor information; and a motion classifying unit (such as) that identifies a movement of the photographing device according to the feature vector generated by the feature vector generating unit (), on the basis of an association between the feature vector and the movement of the photographing device, the association being obtained as a result of previously-executed machine learning of the feature vector and an actual movement of the photographing device. The constraint condition generating unit () determines the range corresponding to the information of the movement of the photographing device, the movement being identified by the motion classifying unit (such as).
