ABSTRACT:
A wide-field image input device that joins a series of partial images obtained by continuously imaging an imaging object by an imaging device while the imaging device is manually scanned by a user, thereby generating a wide-field image, includes: a camera position/posture estimation unit for receiving a partial image series and calculating a change state of three-dimensional position and posture of the imaging device as time-series camera position/posture information; a deformation parameter estimation unit for calculating a geometrical deformation parameter between adjacent partial images from the camera position/posture information; an image joining unit for joining the partial images by using the geometrical deformation parameter so as to generate a wide-field image; and a camera scan error detection unit for detecting motion of the imaging device according to the camera position/posture information and outputting a camera scan error detection signal when an error is detected.
