Provided is a vibration wave motor including a pressurizing mechanism and a guide mechanism which are used for a moving member and can be thinned. The influence of a restoring force can be eliminated. The vibration wave motor includes an elastic vibration member which is composed of a permanent magnet and a piezoelectric element which are fixed to each other, a plurality of motion extraction portions provided on the permanent magnet, and a moving member which is pressurized to be in contact with the plurality of motion extraction portions. A closed magnetic circuit of a magnetic flux is formed to connect between the elastic vibration member and the moving member through the plurality of motion extraction portions. A flow direction of the magnetic flux passing through the moving member is aligned with a moving direction of the moving member.

An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds a threshold. A controller selectively transfers acquired images for storage. A motion extractor determines motion parameters of a selected, stored image. An image re-constructor corrects the selected image with associated motion parameters. A selected plurality of images nominally of the same scene are merged and corrected by the image re-constructor to produce a high quality image of the scene.

A surveillance video processing method including selecting at least one target object from a surveillance area, capturing image information of the surveillance area, detecting motion has occurred in the surveillance area using the captured image information, extracting feature data of an object causing the detected motion, comparing the extracted feature data of the object causing the detected motion and feature data of the at least one target object, and determining whether or not to perform a recording operation for recording the captured image information based on a result of the comparing step.

A motion analysis apparatus is provided that enables an analysis result presentation quantity to be easily adjusted. A motion analysis apparatus (300) is an apparatus that performs analysis of motion subject to comparison (compared motion) by means of comparison with standard motion, and has a motion feature extraction section (321) and motion extraction section (322) that determine a location where a degree of difference between a motion subject to comparison and a standard motion satisfies a predetermined condition, a presentation quantity input section (323) that receives a specification of a presentation quantity of locations that satisfy the predetermined condition, and a motion extraction degree adjustment section (324) that adjusts the predetermined condition so that a quantity of locations satisfying the predetermined condition becomes the specified presentation quantity.

A graphic system includes a pipelined graphic engine for generating image frames for display. The pipelined graphic engine includes a geometric processing stage for performing motion extraction, and a rendering stage for generating full image frames at a first frame rate for display at a second frame rate. The second frame rate is higher than the first frame rate. A motion encoder stage receives motion information from the geometric processing stage, and produces an interpolated frame signal representative of interpolated frames. A motion compensation stage receives the interpolated frame signal from the motion encoder stage, and the full image frames from the rendering stage for generating the interpolated frames. A preferred application is in graphic systems that operate in association with smart displays through a wireless connection, such as in mobile phones.

An object of the present invention is to enable the detection of a mixture ratio indicating the mixture state of a plurality of objects, such as a background image and a moving object image. A normal-equation adder 541 extracts mixed pixel data according to a motion, and also extracts background pixel data corresponding to the mixed pixel data so as to generate relational expressions for a designated pixel. A normal-equation calculator 542 detects the mixture ratio indicating the mixture state of the objects based on the relational expressions. The normal-equation adder 541 generates the plurality of relational expressions based on a first approximation in which foreground object components change substantially linearly, and a second approximation in which the mixture ratio changes substantially linearly. The present invention is applicable to a signal processing apparatus for processing images.

An image recognition apparatus includes an image recognition unit, an evaluation value calculation unit, and a motion extraction unit. The image recognition unit uses motion vectors that are generated in the course of coding image data into MPEG format data or in the course of decoding the MPEG coded data by the evaluation value calculation unit and the motion extraction unit as well as two dimensional DCT coefficients and encode information such as picture types and block types for generating the evaluation values that represent feature of the image. The apparatus further includes an update unit for recognizing the object in the image based on the determination rules for a unit of macro block. The apparatus can thus accurately detect the motion of the object based on the evaluation values derived from DCT coefficients even when generation of the motion vectors is difficult.

A motion estimator and motion estimating method are provided for dividing a current frame into a plurality of blocks and estimating motion by comparing a current block with a previous frame. The motion estimator comprises a mean motion estimation unit for computing a mean motion vector based on motion vectors of surrounding blocks adjacent to the current block, a line motion generation unit for generating a line motion vector in a predetermined search area based on motion vectors of horizontal blocks of the current block, and a motion vector selection unit for selecting and outputting one of the mean motion vector and the line motion vector as a final motion vector of the current block based on a mean motion expectation error value in accordance with the mean motion vector and a line motion expectation error value in accordance with the line motion vector. Aspects of the present invention provide a motion estimator for searching correct motion vectors in the case of moving objects or occurrence of scrolling text against a moving background.

A method of controlling a digital photographing apparatus successively photographs one short exposure image and a plurality of long exposure images. A global motion of each of the long exposure images is compensated based on the one short exposure image. A Point Spread Function (PSF) of each of the one short exposure image and the long exposure images are extracted. A shake correction image is extracted through a repeat estimation by determining an initial value of the repeat estimation based on the one short exposure image and the long exposure images and using each PSF.
