Electronic paper reading system
First Claim
1. An electronic paper reading device comprising:
- a reading component for optically reading an electronic paper which is filled out by hand, in a state in which a first image which has been recorded on the electronic paper in advance, being displayed;
a recognition component for recognizing the first image; and
an extracting component for extracting image data of a second image that represents contents with which the electronic paper is filled out by hand, based on a recognizing result of the recognition of the first image by the recognition component, from a result of the reading by the reading component.

Abstract
Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

10. An electronic paper reading device comprising:
-
a reading component for optically reading an electronic paper which is filled out by hand in a state in which a first image which is recorded in advance on the electronic paper is being displayed, wherein the electronic paper is filled out by hand by using ink having characteristics such that a reflectance of the ink is different from that of the electronic paper within a predetermined wavelength region in which a difference of at least one of a reflectance and a light emitting energy between a portion on the electronic paper at which the first image is recorded and a portion on the electronic paper at which the first image is not recorded thereon is less than a predetermined value, and the reading component obtains image data of a second image that represents contents with which the electronic paper is filled out by hand by optically reading the electronic paper by using a sensor which is sensitive to the predetermined wavelength region. - View Dependent Claims (11, 12)

13. An electronic paper reading system comprising:
-
an electronic paper reading device; and
a control device, wherein the electronic paper reading device and the control device are connected to each other via a network so as to be able to communicate with each other, the electronic paper reading device including;
a reading component for optically reading an electronic paper which is filled out by hand, in a state in which a first image which has been recorded on the electronic paper in advance is displayed;
a recognition component for recognizing the first image; and
an extracting component for extracting image data of a second image that represents contents with which the electronic paper is filled out by hand, based on a recognizing result of the first image by the recognition component and a reading result due to the reading component, and wherein the control device recognizes identification information for identifying the electronic paper which is filled out by hand, and associates the obtained image data of the second image with the identification information and manage the image data.

14. An electronic paper reading method comprising the steps of:
-
(a) optically reading an electronic paper which is filled out by hand in a state in which a first image which has been recorded on the electronic paper in advance, is being displayed;
(b) recognizing the first image; and
(c) extracting, from a result of the reading in the step (a), image data of a second image that represents contents with which the electronic paper is filled out by hand, based on a recognized result from the first image in the step (b).
