摘要： Both tilt information included in an image and positional information are acquired in order to calculate a relative tilt angle between at least two images. Whether the tilt information can be used to estimate the tilt angle (whether the tilt information is fake information) is determined from a distribution characteristic in the image of the acquired positional information. The tilt angle is estimated from the tilt information determined to be able to be used. A tilt included in the acquired image is corrected using the estimation result, and the image having the correct orientation can be produced.

摘要： 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 (130) that generates a constraint condition using sensor information such that a parameter value falls within a range; and a parameter calculating unit (140) that calculates the parameter according to the constraint condition. The constraint condition generating unit (130) has: a feature vector generating unit (131) that generates a feature vector showing features of the sensor information; and a motion classifying unit (such as 132) that identifies a movement of the photographing device according to the feature vector generated by the feature vector generating unit (131), 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 (130) 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 132).

摘要： A decoding device improves a cache hit rate in a decoding process of compressed encoded image data. The decoding device, before the decoding process, generates a sort table for each reference picture for a plurality of MPEG data streams included in a GOP and having a frame type of P- or B-picture. The decoding device, by using the generated sort table, selects a group of pictures composed of a plurality of decoding target macro blocks that refer to the same reference macro block. The decoding device obtains, from the reference picture, four macro blocks including the same reference macro block referred to by the selected picture group, and stores the four macro blocks into the cache memory. The decoding device sequentially decodes each decoding target macro block included in the selected picture group, by using the four macro blocks stored in the cache memory.
