  • Patent number: 7978930
    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.

  • Patent number: 7227557
    Abstract: A capture device 3 first captures the whole of a document 2 and thereby obtains a total image of the document 2. A structure analysis section 24 conducts image structure analysis to the total image, and thereby extracts structural elements (text, figure, picture, etc.) of the document 2 and obtains position information of the structural elements. For each of one or more selected structural elements, a sub-image acquisition process is conducted, in which a control information generation section 25 determines one or more partial areas and a resolution to be used for capturing the selected structural element and an image acquisition control section 23 acquires sub-images of the partial areas of the structural element by use of the capture device 3 with the determined resolution. An image connection section 26 connects the sub-images together and thereby obtains a high resolution image (synthesis target image) of the structural element.
