Abstract

An image processing apparatus includes a control unit and an output unit. The control unit includes an image output unit that arranges an image read by reading processing in an area shifted in a certain direction in a display area in which read image on which reading processing is performed by an image reading apparatus is displayed, and outputs the image to the output unit.

Claims

1. An image processing apparatus, comprising:

a control unit and an output device, wherein

the control unit includes

a mark detecting unit that, when a document on which reading processing is performed is read by an image reading apparatus along with an identification mark, detects the identification mark from an image of the document read;

a position detecting unit that, when the identification mark is detected by the mark detecting unit, determines which portion of the document is read from the image of the document; and

a notification output unit that outputs notification information indicating a read position to be read next time to the output device on the basis of which portion of the document is read as determined by the position detecting unit, wherein

the identification mark is inserted at a top edge of the document along a document fold line, outside the document area and

the identification marks is identified based on color and/or pattern.

2. The image processing apparatus according to claim 1, wherein the control unit further includes an image output unit that arranges an image read by the reading processing in an area shifted in a certain direction in a display area for displaying a read image on which the reading processing is performed by the image reading apparatus, and outputs the image to the output device.

3. The image processing apparatus according to claim 2, wherein the image output unit arranges an image read by a next reading processing in a remaining area of the display area, and outputs the image to the output device.

4. The image processing apparatus according to claim 2, wherein

the position detecting unit detects a display position of the document in the image of the document from the image of the document when the identification mark is detected by the mark detecting unit, and

the image output unit arranges the image read by the reading processing in the display position determined by the position detecting unit, and outputs the image to the output device.

5. The image processing apparatus according to claim 1, wherein, the control unit further includes a read control unit that performs any one or both of an end and a cancellation of the reading processing.

6. The image processing apparatus according to claim 5, further comprising a storage unit that stores the image read by the reading processing of the image reading apparatus, wherein

the read control unit issues any one or both of an end instruction and a cancel instruction of the reading processing, and

when the image reading apparatus sequentially reads portions of the document, the read control unit discards an image read by the reading processing when the cancel instruction is issued, and stores an image read by the reading processing in the storage unit when the end instruction is issued.

7. The image processing apparatus according to claim 1, wherein the control unit further includes

a deskew/cropping executing unit that executes any one or both of deskew and cropping on the image of the document on the basis of the display position detected by the position detecting unit, and

a combining unit that combines the images of the document on which any one or both of deskew and cropping have been executed by the deskew/cropping executing unit.

8. An image processing method performed in a control unit of an image processing apparatus, the apparatus including the control unit and an output device, the method comprising:

a mark detecting step of, when a document on which reading processing is performed is read by an image reading apparatus along with an identification mark, detecting the identification mark from an image of the document;

a position detecting step of, when the identification mark is detected at the mark detecting step, determining which portion of the document is read from the image of the document; and

a notification output step of outputting notification information indicating a read position to be read next time to the output device on the basis of which portion of the document is read as determined at the determining step or the position detecting step, wherein

the identification mark is inserted at a top edge of the document along a document fold line, outside the document area and

the identification marks is identified based on color and/or pattern.

9. A non-transitory computer-readable recording medium including programmed instructions for image processing, the instructions, when executed by a control unit of an image processing apparatus, the apparatus including the control unit and an output device, causing the control unit to perform:

a mark detecting step of, when a document on which reading processing is performed is read by an image reading apparatus along with an identification mark, detecting the identification mark from an image of the document read;

a position detecting step of, when the identification mark is detected at the mark detecting step, determining which portion of the document is read from the image of the document; and

a notification output step of outputting notification information indicating a read position to be read next time to the output device on the basis of which portion of the document is read as determined at the determining step or the position detecting step, wherein

the identification mark is inserted at a top edge of the document along a document fold line, outside the document area and

the identification marks is identified based on color and/or pattern.
