Abstract

The size of image data for a check or other negotiable instrument used for electronically clearing payments made by such negotiable instruments is reduced. A scanning process setup command received from a host system by a communication unit is interpreted by the command interpreting unit and settings for a specified image reading area and/or cropping areas to are stored in control data storage unit. The image reading unit is controlled and driven by the scanning control unit, and an image of the negotiable instrument is read by scanning the specified image reading area. An image cropping unit extracts only the image data in the specified cropping areas.

Claims

1. A negotiable instrument processing apparatus comprising:

an image reading unit that scans a negotiable instrument, captures an image the negotiable instrument, and outputs image data;

a size detection unit that detects a size of the negotiable instrument;

a reading area setting unit that is responsive to a first input to set a reading area for scanning by the image reading unit, the first input

(a) directly setting the reading area according to parameters representing x and y coordinates values specified by the first input without detecting the size of the negotiable instrument by the size detecting unit when the parameters equal first values, and

(b) automatically setting the reading area according to the size detected by the size detection unit when the parameters equal second values; and

a scanning control unit that controls driving the image reading unit according to the reading area.

2. The apparatus of claim 1, wherein the first input is a first control command from a host system.

3. The apparatus of claim 1, wherein the reading area set by the reading area setting unit is rectangular, and the reading area setting unit sets the reading area based on a starting point and ending point specified by the first input at diagonally opposite corners of the rectangle.

4. The apparatus of claim 3, wherein the starting point and ending point specified by the first input are specified as coordinates of an orthogonal coordinate system of which a first axis is a direction of negotiable instrument movement relative to the image reading unit and a second axis is a direction orthogonal to the direction of relative movement.

5. The apparatus of claim 1, wherein the size detection unit detects at least a length of the negotiable instrument in a direction orthogonal to a direction of movement of the negotiable instrument relative to the image reading unit based on the image data output from the image reading unit.

6. The apparatus of claim 1, further comprising a transportation unit that conveys the negotiable instrument along a transportation path;

and

first and second paper detection units positioned along the transportation path with a specific interval therebetween that detect presence of a negotiable instrument in the transportation path;

the size detection unit further detecting negotiable instrument length in the transportation direction based on the specific interval, information relating to the transportation distance from the transportation unit, and detection information from the paper detection units.

7. The apparatus of claim 1, further comprising a cropping area setting unit that is responsive to a second input to set at least one cropping area for capturing a part of the image data;

and

an image cropping unit that captures data within the at least one cropping area from the image data.

8. The apparatus of claim 7, wherein the second input is a second control command from the host system.

9. The apparatus of claim 7, wherein a cropping area set by the cropping area setting unit is rectangular, and the cropping area setting unit sets the cropping area based on a starting point and ending point specified by the second input at diagonally opposite corners of the rectangle.

10. The apparatus of claim 7, wherein the starting point and ending point specified by the second input are specified as coordinates of an orthogonal coordinate system of which a first axis is a direction of negotiable instrument movement relative to the image reading unit and a second axis is a direction orthogonal to the direction of relative movement.

11. The apparatus of claim 7, wherein the cropping area setting unit deletes a cropping area based on a third input.

12. The apparatus of claim 11, wherein the third input is a third control command from the host system.

13. A negotiable instrument processing method comprising:

receiving a first input, the first input

(a) directly setting a reading area for capturing an image of the negotiable instrument according to parameters representing x and y coordinate values specific by the first input without detecting a size of the negotiable instrument when the parameters equal first values, and

(b) detecting a size of the negotiable instrument and automatically setting the reading area for capturing an image of the negotiable instrument according to the size detected when the parameters equal second values;

setting the reading area based on

reading area settings specified by x and y coordinate values received in the first input receiving step if directly setting is specified by the first input, and

the size detected by the size detection unit if automatic setting is specific by the first input; and

scanning a negotiable instrument, capturing an image thereof, and outputting image data based on the reading area set in the reading area setting step.

14. The method of claim 13, further comprising receiving a second input, the second input including cropping area settings specifying at least one cropping area for capturing a part of the image data output in the image reading step;

setting a cropping area based on the cropping area settings input in the second input step; and

capturing data within the cropping area from the image data output in the scanning, capturing and outputting step.

15. The method of claim 14, further comprising receiving a third input, the third input including a cropping area deletion instruction for deleting a cropping area;

and

deleting a cropping area based on the cropping area deletion instruction.
