Patent ID: 7978930

Claim:
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, the device comprising: camera position/posture estimation means for receiving a partial image series including said series of partial images, and calculating a change state of three-dimensional position and posture of said imaging device as time-series camera position/posture information; deformation parameter estimation means for calculating a geometrical deformation parameter between adjacent partial images in said partial image series from said camera position/posture information; image joining means for joining said partial images while a deformation between said partial images is corrected by using said geometrical deformation parameter so as to generate a wide-field image; and camera scan error detection means for detecting motion of said imaging device according to said camera position/posture information, and outputting a camera scan error detection signal when an error is detected in the motion of said imaging device.
