摘要

An image processing device for calculating the parameter for highly precisely correcting a large image shake even when the precision of a sensor for measuring the movement of a photographing device is low. The image processing device comprises a constraint condition generating section (130) for generating a constraint condition under which the parameter is a value within a predetermined range by using sensor information and a parameter calculating section (140) for calculating the parameter according to the constraint condition. The constraint condition generating section (130) includes a feature vector generating part (131) for generating a feature vector indicating the feature of the sensor information and a movement discriminating part (132, etc.) for discriminating the movement of the photographing device from the feature vector generated by the feature vector generating part (131) on the basis of the association between the feature vector and the movement of the photographing device, which is obtained by previously machine-learning the movement of the feature vector and the actual movement of the photographing device. The constraint condition generating section (130) specifies the predetermined range according to information on the movement of the photographing device discriminated by the movement discriminating part (132, etc.).
