6A and 6B explain the calculation of the correction amount for correcting the transfer deviation of the original image by the calculation unit 730, FIG. 6A is a diagram showing the original document D to be read, and FIG. 6B is a diagram showing the original image to be read. 6 (C) is a diagram showing the original image I corrected so as to rotate the read original image I, and FIG. 6 (D) is a diagram showing the original image I corrected to rotate the read original image I. It is a figure which shows the original image I which was further corrected so as to reduce the distortion of the corrected original image.

As shown in FIG. 6A, if the scanning direction L1 in which the scanning unit 140 scans the document D and the tip end L2 of the document D conveyed in the arrow b direction are not parallel, the scanning unit 140 reads the document. When the original image I is tilted and the read original image I becomes a parallel quadrilateral as shown in FIG. 6 (B), a transport deviation occurs. Therefore, the calculation unit 730 rotates the entire original image I in the direction indicated by the arrow c to calculate the inclination correction amount which is the correction amount for reducing the inclination of the original image.

When the original image I is corrected to rotate from the position shown by the broken line in FIG. 6 (C) to the position shown by the solid line in FIG. 6 (C) using the tilt correction amount, it is shown by the solid line in FIG. 6 (C). In addition, the original image I is distorted, and the original image I, which is originally rectangular, has a parallelogram or a trapezoidal transport deviation. Therefore, the calculation unit 730 corrects the squareness of the original image I and calculates the squareness correction amount which is the correction amount for reducing the distortion of the original image I. When the original image I is further corrected from the shape shown by the broken line in FIG. 6 (D) to the shape shown by the solid line in FIG. 6 (D) using the squareness correction amount, the original image I is changed to FIG. 6 (D). As shown by the solid line, the distortion is reduced.

FIG. 7 is a diagram illustrating an operation of a correction amount for correcting the transfer deviation of the original image by the calculation unit 730 from the image data acquired by reading the test chart original. As shown in FIG. 7 (E), in the test chart manuscript D2, a line E1 is drawn in the main scanning direction in which the reading unit 140 scans the manuscript along the reading tip (edge) of the test chart manuscript D2. The line V1 is drawn in the sub-scanning direction perpendicular to the main scanning direction described above, and the line E1 and the line V1 are in a vertical relationship.

As shown in FIG. 7A, the scanning direction L1 in which the reading unit 140 scans the test chart document D2, the tip L2 of the test chart document D2 conveyed in the direction of the arrow b, and the vicinity thereof along the tip L2. If the line E1 drawn is not parallel, the original image I2 read by the reading unit 140 is tilted, and the original image I2 read as shown in FIG. 7B becomes a parallel quadrilateral, and the read test is performed. As the image of the chart manuscript D2, the manuscript image I2 of the line E2 and the line V2 as shown in FIG. 7B is generated.

Therefore, the calculation unit 730 calculates the angle between the line E2 of the manuscript image I2 of the test chart manuscript D2 shown in FIG. 7B and the reference line S1, rotates the whole in the direction indicated by the arrow c, and the manuscript. The tilt correction amount, which is the correction amount for reducing the tilt of the image, is calculated. The reference line S1 may be set perpendicular to this direction as long as the directions of the edges on both sides of the original image I2 of the test chart original D2 can be detected, or may be perpendicular to the line V2 of the original image I2 of the test chart original D2. It may be set in the direction of.

When the original image I2 of the test chart original D2 is corrected to rotate using the tilt correction amount calculated as described above, the original image I2 corrected to rotate is as shown in FIG. 7 (C). The line E3 and the line V3 are drawn, the original image I2 is distorted, and the original image I2, which is originally a rectangle of the test chart original D2, becomes a parallelogram or a trapezoid. Therefore, in order to correct the squareness of the original image I2, the calculation unit 730 sets a reference line S2 perpendicular to the line E3 from the intersection of the line E3 and the line V3, and sets the reference line S2 and the line V3. Calculate the squareness correction amount, which is the amount of deviation. When the original image I is further corrected by using the squareness correction amount which is the correction amount for reducing the distortion of the original image I, the original image I has the distortion reduced as shown in FIG. 7 (D). Become.

The tilt correction amount and the squareness correction amount described above are stored in the storage unit 780 by the storage control unit 740. Then, when the document D is read by the document reading device 100, the tilt correction amount and the squareness correction amount are read from the storage unit 780, and the document is used by using the read tilt correction amount and the squareness correction amount. The original image I read by the reading device 100 is corrected.

In the document reading device 100, the document image I read as described above is corrected by using the tilt correction amount and the squareness correction amount stored in the storage unit 780. Therefore, for example, before shipping. For example, it is not necessary to adjust the physical positional relationship between the document transport mechanism 300 and the reading unit 140.

The tilt correction amount and the squareness correction amount described above may be calculated by the calculation unit 730 for both one surface of the document D and the other surface of the document D, and stored in the storage unit 780. desirable. That is, the tilt correction amount and the squareness correction amount of the surface conveyed from the document base 120 of the document D and first read by the reading unit 140, and the inversion transport path 304 of the document D are passed, inverted, and then read by the reading unit 140. It is desirable to calculate both the tilt correction amount and the squareness correction amount of the surface to be formed and store them in the storage unit 780.

In the control unit 700 described above, the calculation unit 730 calculates the correction amount for correcting the transfer deviation of the original image received by the original image reception unit 720 by the calculation unit 730, and the calculation unit 730 calculates the correction amount. Although the storage control unit 740 stores the data in the storage unit 780, the storage control unit 740 may store the data regarding the transfer deviation of the original image received by the document image reception unit 720 in the storage unit 780.

When the storage unit 780 stores the data related to the transport deviation of the original image, when the document D is read by the document reading device 100, the data related to the transport deviation is read from the storage unit 780 and read. The original image I read by the original reading apparatus 100 is corrected by using the data regarding the transferred transfer deviation.

FIG. 8 is a diagram showing a second example of the image processing apparatus 10 used in the embodiment of the present invention. In the first example of the image processing device 10 described above, the document reading device 100 has one reading unit 140 and an inverted transfer path 304, and after reading one surface of the document D by the reading unit 140, Both sides of the document D were read by inverting the document D using the reverse transfer path 304 and reading the other side of the document D with the reading unit 140.

On the other hand, in this second example, the document reading device 100 does not have the reverse transfer path 304, and the reading unit 140a for reading one surface of the document D and the reading unit 140b for reading the other surface of the document D. The image on both sides of the document being conveyed through the main transport path 302 is configured to be simultaneously read by the reading unit 140a and the reading unit 140b.

Further, in the first example of the image processing device 10 described above, the output from the reading unit 140 was input to the control circuit 702. On the other hand, in this second example, the output from the reading unit 140a and the output from the reading unit 140b are input to the control unit 700, respectively. Then, using the original image input from the reading unit 140a, the calculation unit 730 calculates the tilt correction amount and the squareness correction amount of the original image on one side of the document D. Further, using the original image input from the reading unit 140b, the calculation unit 730 calculates the inclination correction amount and the squareness correction amount of the other surface of the document D.

Further, in the second example of the image processing apparatus 10, the data regarding the transfer deviation of the original image on one side of the document D read by the reading unit 140a and the document on the other side of the document D read by the reading unit 140b Even if the original image on one side of the original image I read by the original reading device 100 and the original image on the other side of the original image are corrected by using the data related to the image transfer deviation. good. Except for the part described above, the second example of the image processing device 10 is the same as the first image processing device 10 described above, so the description of the same part is omitted.
