Abstract
An imaging technology having high reproducibility of a document and making image correction possible, without being influenced by a way of placing the document or a position of a camera, and irrespective of paper color and despite of damage of a corner portion. By printing positioning symbols on document paper in advance when the document is photographed by a digital camera or a portable phone with a camera, such as a smart phone, and by processing the image based on these positioning symbols, image processing having high reproducibility of the document and making image correction (keystone correction) possible can be implemented irrespective of paper color and even when there is damage to a corner portion of the paper.
Claims19
An image processing system, comprising:
- an imaging object having positioning symbols which are disposed in at least two predetermined locations, and are created as symbol codes constituted by multi-valued graphics;
- an imaging unit which images the imaging object;
- an image acquisition unit which detects the positioning symbols from original image data imaged by the imaging unit, recognizing a predetermined area calculated based on the positioning symbols as a first range, and extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- an image data storage unit which stores the extracted image data acquired by the image acquisition unit.
An image processing system, comprising:
- a transparent sheet on which positioning symbols created as symbol codes constituted by multi-valued graphics are disposed in at least two predetermined locations, and which is placed on paper serving as an imaging object;
- an imaging unit which images the imaging object;
- an image acquisition unit which detects the positioning symbols from original image data on the surface of the paper imaged by the imaging unit via the transparent sheet, recognizing a predetermined area calculated based on the positioning symbols as a first range, and extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- an image data storage unit which stores the extracted image data acquired by the image acquisition unit.
An image processing system, comprising:
- two or more seal pieces which are pasted onto paper serving as an imaging object, and each of which is formed of a positioning symbol created as a symbol code constituted by a multi-valued graphic;
- an imaging unit which images the imaging object;
- an imaging acquisition unit which detects the positioning symbols of the seal pieces from original image data on the surface of the paper imaged by the imaging unit, recognizing a predetermined area calculated based on the positioning symbols as a first range, and extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- an image data storage unit which stores the extracted image data acquired by the image acquisition unit.
An image processing system established via a network, comprising:
- an imaging object having positioning symbols disposed in at least two predetermined locations and created as symbol codes constituted by multi-valued graphics;
- an imaging unit which images the imaging object;
- a transmission unit which transmits original image data imaged by the imaging unit via a network;
- an image acquisition unit which, in an image processing server which receives the original image data via the network, detects the positioning symbols from the original image data imaged by the imaging unit, recognizing a predetermined area calculated based on the positioning symbols as a first range, extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- an image data storage unit which stores the extracted image data acquired by the image acquisition unit.
An image processing method used for an image processing system which images, using imaging unit, the surface of an imaging object having positioning symbols disposed in at least two predetermined locations and created as symbol codes constituted by multi-valued graphics, processes original image data thereof by image acquisition unit and registers the processed data in image data storage unit, the image processing method comprising the steps of:
- the imaging unit imaging the imaging object so that at least the positioning symbols in the at least two predetermined locations are included;
- the image acquisition unit detecting the positioning symbols from the imaged original image data, and recognizing a predetermined area calculated based on the positioning symbols as a first range;
- extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- storing the extracted image data in the image data storage unit.

- the imaging unit imaging the imaging object so that at least the positioning symbols in the at least two predetermined locations are included;
- the image acquisition unit detecting the positioning symbols from the imaged original image data, and recognizing a predetermined area calculated based on the positioning symbols as a first range;
- extracting only image data existing in the first range to acquire this image data as extracted image data;
- and
- storing the extracted image data in the image data storage unit.
An imaging object used for an image processing system which includes:
