摘要： An apparatus and a method for correction of a deviation of an imaging sensor of a digital camera in which an image of an object or a scene is formed on an image plane of the imaging sensor to output an image signal, are disclosed. A quantity of rotation of the digital camera causing a deviation of the imaging sensor from a reference position to occur, is detected. A change of a positional angle of the imaging sensor is calculated based on the detected rotation quantity. A target vector is calculated based on the calculated positional angle change, the target vector describing a magnitude and a direction of an inverse movement of the imaging sensor needed to reach the reference position and cancel the deviation. Movement of the imaging sensor is controlled based on the calculated target vector, so that the imaging sensor is moved back to the reference position thus correcting the deviation. The calculation of the target vector and the movement of the imaging sensor are executed within an image acquisition time for a single frame of the image signal.

摘要： In image processing method and apparatus of the present invention, image distortions caused by oblique imaging are corrected. A feature point of one of a plurality of partially overlapping images corresponding to a common location of an original image, shared by the plurality of partially overlapping images, is determined. A matched point of one of the other partially overlapping images corresponding to the feature point is determined so that a direction of the object plane is calculated based on the feature point and the matched point. One of the plurality of partially overlapping images is selected as a standard image whose image distortions are to be corrected. A distortion-corrected image is generated on a projection plane by projecting the standard image onto the projection plane based on the direction of the object plane such that image distortions in the standard image are eliminated.

摘要： An image capturing apparatus for capturing an image of an object. The image capturing apparatus includes a correspondence detector which detects a correspondence of characteristic points of an object based upon captured images of the object. A motion detector detects a motion of the image capturing device. The motion detector includes magnetic sensors. Further, a shape calculator calculates a shape of the object based upon the captured image data, captured attitude information, a translation component, and the correspondence of the characteristic points. The motion detector may further include acceleration sensors and angle speed sensors. A disturbance detector may further be provided to detect a disturbance in acceleration signals output by the acceleration sensors and a disturbance in magnetic signals output by the magnetic sensors. In this situation, if a disturbance arises in the acceleration signals output by the acceleration sensors, an attitude of the image capturing apparatus can be based on signals output by the magnetic sensors and signals output by the angle speed sensors. Similarly, if a disturbance arises in the magnetic signals output by the magnetic sensors, an attitude of the image capturing apparatus can be determined utilizing the acceleration signals output by the acceleration sensors and the angle speed signals output by the angle speed sensors.

摘要： The image input apparatus comprises the image pickup unit which optically scans a subject and successively acquires partial images of the subject. The relative change detection unit detects an amount of relative change in position or speed of the image pickup unit between a time when a previous partial image was taken and a time when a current partial image is being taken. The an overlapping amount calculating unit calculates an amount of overlap between the previous partial image and the current partial image based upon the amount of relative change in position or speed detected by the relative change detection unit. The image recording determination unit determines whether or not the current partial image is to be recorded based upon the amount of overlap calculated by the overlapping amount calculating unit.
