[0063] The image pickup device according to the first embodiment is generally configured to position and superimpose a plurality of still images picked up by the image pickup device or imager on each other to reduce noise of the images.

[0064] In an environment where a user holds an image pickup device to pick up an image, camera shake may occur. For example, in the case of picking up still pictures by continuous shooting with an image pickup device held by the user in this way, the first still picture is used as a target frame and the second and subsequent still pictures are used as reference frames.

[0065] In a case where a reference frame can be positioned at a target frame position by applying transformation processing including parallel translation, rotation, and expansion or contraction to the entire reference frame, the transformation processing applied to the entire reference frame is a global motion. Global motion generally represents the movement and amount of th...

[0305] In the above-described embodiments, the local motion vector calculation section 154 performs hierarchical block matching to calculate the local motion vector LMV on the base plane. Then, the motion vector reliability index value calculation section 156 calculates the reliability index value Ft of the local motion vector LMV with respect to the base plane. Furthermore, the global motion vector calculation section 157 extracts those local motion vectors LMV with high reliability using the reliability index value Ft of the local motion vector LMVs of the base plane, and calculates the global motion vector LMV using the local motion vector LMV with high reliability. Motion vector GMV.

[0306] Incidentally, the base plane motion vector MVb can be obtained by multiplying the reduction plane motion vector MVs and the intermediate plane motion vector MVm by the reciprocal of the image reduction rate of the base plane. Therefore, in order to calculate the global motion vector ...

Abstract

The present invention discloses an image processing apparatus and an image processing method. The image processing apparatus includes: motion vector detection section configured to detect a motion vector of each of a plurality of blocks of a predetermined size set in an image and formed from a plurality of pixels; and global motion calculation section configured to carry out convergence mathematical operation, from the motion vectors of the blocks detected by the motion vector detection section, using extended affine transformation in which at least one of affine parameters is represented by afunction of a variable regarding a displacement axis of the image to calculate a global motion representative of deformation applied to the entire image.

Description

[0001] References to related applications [0002] The present invention contains subject matter disclosed in Japanese Priority Patent Application JP 2008-105248 filed in the Japan Patent Office on Apr. 15, 2008, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an image processing device and an image processing method for calculating a global motion representing deformation of an entire image between two screen images. Background technique [0004] The block matching technique of determining the motion vector between two pictures based on the image information itself is a technique with a long history. [0005] The block matching technique is a method for calculating a motion vector between two pictures including: a reference picture, which is a picture of interest; and an original picture (hereinafter, referred to as a target picture), a reference picture The motion of is derived from this original f...
