Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an image processing apparatus for recording an original image on recording paper in a borderless copy mode for enlarging an image read entirely from an original by image reading means at a predetermined magnification and recording the recording image on recording paper, a control method therefor, And its control program.
[0002]
[Prior art]
Conventionally, an image reading apparatus has been commercialized as a peripheral device (image scanner) for a single function computer, as well as a facsimile machine and a copying machine, and more recently, a plurality of functions such as image reading, copying, and facsimile transmission have been combined. Widely used for MFPs (Multi Function Peripherals).
[0003]
In many image reading devices, reading scanning is performed by the relative movement between the reading head and the document.However, if the reading method of the image reading device is classified according to the document conveying method, the document is placed on the document glass and read. There are a method of moving the head, and a method of moving the original without moving the reading head. In addition to manual feeding, a configuration in which an original is sent to a reading position (regardless of whether the original or the reading head is fed) by an ADF (automatic original feeding device) is used. ing.
[0004]
Further, it is not uncommon for current image reading apparatuses to be able to use not only a single reading method but also two or more reading methods. For example, an apparatus that can use both the ADF reading method and the flatbed reading method is available. Exists.
[0005]
In addition, at present, not only is the image of the read document simply recorded on the recording paper or transmitted by facsimile, various controls are performed during the process from reading the document to using the document image. Accordingly, it has become commonplace to implement a plurality of different processing functions on a document image.
[0006]
For example, there are the following types of copy functions even if only the copy (copy) is listed.
[0007]
(1) Normal copy that simply copies the original (2) Repeated copy (manual) in which the original is repeatedly copied onto the recording paper by the number of repetitions specified by the operator
(3) Repeat copying to copy the original as much as possible on the recording paper (automatic)
(4) Mirror image copy for inverting and copying an original as if mirrored on a mirror (5) Automatic magnification copy for automatically determining the magnification and copying the entire recording paper size (6) Non-image area (recording) Borderless copy for copying an original over the entire surface of recording paper without margins around the paper
[Problems to be solved by the invention]
As described above, the image reading apparatus may be required to have a configuration capable of using a plurality of reading methods such as an ADF reading method and a flatbed reading method. It is desirable that image processing can be performed by selecting a plurality of reading methods as simply and without error as possible.
[0009]
For example, in a method in which a plurality of reading methods are simply selected by a manual operation, the burden on the user is large, and there is a high possibility that the target image processing fails due to an operation error or the like. In particular, as the apparatus has more functions (for example, various copy functions exist as described above even for copy (copy)), an improper reading method is selected due to an operation error and image processing fails. The likelihood increases.
[0010]
For example, in the control of the reading process by a manual operation, there is a possibility that a reading method in which the entire surface cannot be read may be selected even though the image reading mode in which the entire surface of the document is required is selected.
[0011]
As the image reading mode that requires reading of the entire surface of the document, there is a borderless copy (6) among the above-described copy modes. Borderless copying refers to recording an image read from a document on the entire surface of a recording sheet without a surrounding margin (or with a very small margin). At this time, when reading, it is necessary to read the entire surface of the document almost completely without missing.
[0012]
In the case of the ADF-type reading means, there are some reading means which cannot read the entire surface due to manufacturing costs and product specifications. Cannot copy.
[0013]
Therefore, in a configuration in which various reading modes can be selected, such as performing or not performing borderless printing, and a plurality of reading modes can be used, the reading can be reliably performed without any additional operation by the user. Desirably, processing can be performed.
[0014]
Under the circumstances described above, there is a strong demand for a configuration capable of performing borderless copying efficiently and reliably with a simple and inexpensive configuration.
[0015]
In addition, the conventional borderless copy has a problem that the setting operation is complicated. In borderless copying, when reading, the entire image is read almost completely from the entire surface of the document, and furthermore, the image is recorded on the entire surface of the recording paper. After the enlargement, output to the printer engine is performed. Such enlargement processing is necessary for performing more complete (or marginless) marginless printing. If the enlargement / centering as described above is performed, even if the original size and the recording paper size are borderless copies of the same size, there is an error in the original position and an error in the reading / recording accuracy. There is a possibility that the margin around the recording paper may become large to the extent that “None” cannot be marked.
[0016]
Conventionally, when a user selects borderless printing, it is necessary to manually set numerical values such as a margin amount and an enlargement magnification necessary for controlling the image processing. Appropriate default values may be used as these necessary control parameters based on the document size and the like.However, such control does not allow stable margin control and ensures good-looking borderless printing. May not be.
[0017]
In view of the above problems, it is an object of the present invention to provide a highly functional and complex image processing system that performs borderless copying and the like so that image processing can be performed efficiently and reliably with a simple and inexpensive configuration. And
[0018]
[Means for Solving the Problems]
According to the present invention, in order to solve the above-described problem, an original image is recorded on a recording paper in a borderless copy mode in which an image read from the entire surface of the original by an image reading unit is enlarged at a predetermined magnification and recorded on the recording paper. In the image processing apparatus for recording, the control method thereof, and the control program thereof, the user sets the amount of protrusion corresponding to the size of the image that is out of the recording paper and becomes non-recorded by enlarging the document image, and is set by the user. Based on the amount of protrusion, a configuration is adopted in which the magnification ratio at the time of the enlargement is determined.
[0019]

[0045]
FIG. 3 shows a configuration of a main part of an image reading unit of the MFP of FIG. As shown in the figure, the image reading unit of the present embodiment is configured to use two image reading methods, that is, an ADF and a flatbed method.
[0046]
In FIG. 3, the ADF and the flatbed image reading unit share some members (image sensor and black-and-white reference plate in the present embodiment) except members related to document conveyance. In FIG. 3, a black-and-white reference plate 1810 is arranged below a document table 1807 and generates shading data of an image sensor 1806. The black-and-white reference plate 1810 is composed of two color portions, that is, a white portion and a black portion. The image sensor 1806 is moved below the black-and-white reference plate 1810, and an illumination light source (not shown) of the image sensor 1806 is provided below the image sensor 1806. By turning on or off, shading data of each color can be obtained.
[0047]
The document abutting position 1809 is a abutting position serving as a reference for arranging the leading edge of the document serving as a reference for correctly stacking the documents on the document table 1807.
[0048]
The pressure plate 1811 is a lid for preventing external light from entering when reading a document, and the inside thereof is made of a white sheet.
[0049]
An image sensor 1806 is arranged below a document table 1807 made of transparent glass, scans a document 1808 on the document table 1807 by a driving unit (not shown), and reads an image thereof. When the apparatus is in a standby state (except when the ADF reading method is selected), the image sensor 1806 stands by at the image sensor home position 1805.
[0050]
The image sensor 1806 and the black-and-white reference plate 1810 are also used for reading using the ADF.
[0051]
An ADF is arranged on the document table at one end of the flat bed. The ADF may be incorporated into the apparatus from the beginning, or may be configured to be detachable as an optional component.
[0052]
The ADF has a transport unit 1812 including rollers for transporting documents one by one from a document set position 1801 to a document discharge position 1803, and moves the image sensor 1806 to an ADF reading position 1804 below the transport unit 1812. The image of the automatically conveyed document can be read.
[0053]
A document detection sensor 1802 including an optical sensor and a limit switch is provided at the end of the document set position 1801 of the ADF. The document detection sensor 1802 can detect the presence or absence of a document on the document set position 1801.
[0054]
When the document detection sensor 1802 detects a document, it is assumed that the ADF reading method is selected, the flatbed reading method is not used, and a predetermined operation (such as the operation of the start key 309 in FIG. 2) is performed. ADF reading is performed.
[0055]
In the ADF reading, the image sensor 1806 is moved to the ADF reading position 1804, and while the document is being conveyed toward the document discharge position 1803, the image of that portion is read when the document passes over the ADF reading position 1804.
[0056]
When the document detection sensor 1802 has not detected a document (or by another explicit operation) and the ADF reading method has not been selected, the flatbed reading method is selected. If the flatbed reading method is selected, the image sensor 1806 returns to the image sensor home position 1805 and enters a standby state.
[0057]
In the configuration of the ADF reading unit as shown in FIG. 3, it is difficult to convey in the reverse direction by the conveyance unit 1812 (even if possible, a complicated, expensive, and unrealistic configuration is required). ), And when the ADF reading method is selected, the pre-scan cannot be performed (for the purpose of detecting the document size, etc.).
[0058]
Further, the automatic document conveyance by the ADF reading unit as shown in FIG. 3 is not suitable for a borderless copy operation described later. This is because in the borderless copy operation, it is necessary to control the skew of the original document very strictly and to obtain a sufficient transport accuracy to accurately read the entire original document. This is because it is difficult to obtain high transport accuracy.
[0059]
1 to 3 can perform operations such as image recording, image reading, document copying, facsimile transmission and reception. In the image processing of the MFP of the present embodiment, in particular, in the image processing involving image reading, the image reading means performs reading by any of the above-described flat bed reading method or ADF reading method. It is controlled by the type of the copy mode, in particular, whether or not the detection of the document size is required, or whether or not the entire surface is to be read (such as borderless copy).
[0060]
Hereinafter, the control executed by the CPU 101 will be described with reference to FIG. FIG. 4 shows an outline of control executed by the CPU 101 in the MFP, in particular, control relating to image reading control.
[0061]
In step S401 in FIG. 4, it is determined whether the mode is the copy mode by checking the state of the mode switching key 305. If the mode is the copy mode, the process waits for a copy instruction from the operator (step S402).
[0062]
If the FAX mode is set in step S407, the process waits for a facsimile instruction from the operator in step S408. After the operator sets magnification, density, image quality, recording paper size, mode, and the like, the start key 309 is pressed ( In step S409, facsimile transmission is performed (step S411).
[0063]
If the scan mode is not set in the FAX mode in step S407, the scan mode is set. Therefore, a scan instruction from the connected PC 111 is waited for (step S412). If there is a scan instruction from the PC 111, the scan instruction is issued in step S413. Perform a street scan.
[0064]
If there is no scan instruction from the PC 111, it is checked in step S414 whether the start key 309 has been pressed. If the start key 309 has been pressed, the scan mode is requested to the PC 111 (step S415). If the desired scan mode has been acquired from the PC 111 (step S416), the image reading process according to the acquired scan mode is performed (step S417).
[0065]
In the FAX mode (steps S407 to S407) and the scan mode (steps S412 to S412), the document size may be detected by pre-scan, which will be described later. Document size detection is not performed.
[0066]
If the current state is the copy mode in step S401, after the operator has made copy settings such as magnification, density, image quality, recording paper size, and copy type in step S402, the start key 309 is pressed ( Step S403), the determination of steps S418, S404, and S419 is performed, and copy processing is performed according to the result.
[0067]
First, in step S418, it is determined whether the currently set copy type (copy mode) is borderless copy.
[0068]
If step S418 is denied, it is checked in step S404 whether the currently set copy type (copy mode) is a copy for which original size detection is performed by prescanning.
[0069]
In step S404, if the document size detection by pre-scan is not performed, copy processing without document size detection is performed in the copy mode selected in step S410 (for example, copying is performed using recording paper of a set size). ).
[0070]
On the other hand, when step S418 or step S404 is affirmed, the process proceeds to step S419. If step S418 or step S404 is affirmed, it means that the borderless copy mode that requires reading the entire surface of the document or the copy mode that requires document size detection is selected. Since the ADF reading method is not suitable for these modes as described above, it is determined in step S419 whether or not a document is set on the ADF (ADF reading method is selected). In step S419, the selected state of the image reading method (image reading means) can be detected simply and inexpensively and directly by detecting the presence or absence of a document at the document set position 1801 of the ADF by the document detection sensor 1802.
[0071]
If a document is set on the ADF in step S419 (ADF reading method is selected), an error warning is issued in step S421. That is, an affirmative determination in step S419 means that the ADF reading method has been selected in spite of the necessity of performing full scanning or pre-scanning, and a normal reading operation is not possible. In step S421, an error warning is given to the user to that effect. For example, a message such as "Please remove the document from the ADF and select flatbed reading" is displayed on the display 317, or an error warning is issued by audio output from a speaker.
[0072]
On the other hand, if the original is not set on the ADF in step S419, that is, if the flatbed reading method is selected, in step S420, a borderless copy operation involving full-surface reading of the original described later or the original size detection is performed. Is performed with a copy operation.
[0073]
Whether or not to detect the document size by the prescan described above depends on the copy mode (copy type).
[0074]
It is assumed that the MFP according to the present embodiment can perform six types of copy modes as shown in FIG. That is, the copy modes (copy types) available in the MFP of the present embodiment are as follows.
[0075]
(1) Normal copy that simply copies the original (2) Repeated copy (manual) in which the original is repeatedly copied onto the recording paper by the number of repetitions specified by the operator
(3) After performing pre-scanning to determine the size of the original, repeat copying to copy the original as often as possible on the recording paper (automatic)
(4) Mirror image copying in which an original is mirror-mirror-copied and copied (5) Automatic magnification copying in which prescanning is performed to determine the original size, automatically determine the magnification, and copy the entire recording paper size (6) Borderless copy in which a document is copied over the entire surface of a recording sheet without a non-image area (a margin around the recording sheet) of the recording section.
[0076]
In this embodiment, there are only three types of copies for which the original size is detected by pre-scanning: (3) repetitive copy (automatic), (5) automatic magnification copy, and (6) borderless copy. Document size detection is not necessarily required depending on the copy control method.) If the copy type is original size detection (3) repetitive copy (automatic), (5) automatic magnification copy, or (6) borderless copy (using original size detection), use for actual copy Prior to the image reading process, a prescan is performed to determine the document size.
[0077]
After it is confirmed in step S419 in FIG. 4 that the ADF reading method is not selected, in the copy operation performed in step S420, a copy with original size detection or a marginless copy with full surface reading is performed. become.
[0078]
Borderless copying can be performed by a method as shown in FIGS. FIG. 6 shows an example of a control procedure for executing borderless copying without requiring many cumbersome manual settings. The procedure in FIG. 6 may be performed by the CPU 101 inside step S420 in FIG.
[0079]
In the control of FIG. 6, the user only needs to select one of the two settings of (a) the large amount of protrusion and (b) the small amount of protrusion.
[0080]
Such an operation of selecting the amount of protrusion can be performed by the user through an appropriate user interface using the set key 315, the menu key 316, the display 317, and the like. For example, the setting is made by displaying a protrusion amount setting menu 90 as shown in FIG.
[0081]
The protrusion amount setting menu 90 in FIG. 9 includes a touch panel method or a cursor 91 for setting a protrusion amount, and buttons 92 to 94 for operating with a pointing device. The cursor 91 is operated by an appropriate operation method (using a touch panel, a pointing device, an arrow key, or the like) to determine whether to select “large” or “small” as the “protruding amount” shown on the left side of FIG. When the “OK” button 92 at the bottom is pressed, one of “large” and “small” settings where the cursor 91 is located is input. The "cancel" button 93 and the "return" button 94 are used for the purpose of canceling the setting, returning to the previous menu, and the like.
[0082]
As shown in FIG. 9, according to the present embodiment, the user can control the borderless copy without any setting of the enlargement ratio and the margin, which are conventionally required. ”, The burden on the user is very small, and the setting operation can be easily completed.
[0083]
In step S601 in FIG. 6, it is first checked whether the currently set copy type is borderless copy. If the borderless copy is selected here, the processing of steps S602 to S606 is performed.
[0084]
First, in step S602, the above-mentioned setting of the amount of protrusion performed by the user is read from the memory. If the setting of the amount of protrusion of the user is "small", the process proceeds to step S603, and if it is "large", the process proceeds to step S605 (the default when the user is not set is, for example, "small").
[0085]
If the setting of the amount of protrusion is small, in step S603, the magnification (magnification) magnification of the setting magnification (recording paper print size with respect to the document size) × 1.05 is set, and the setting of the amount of protrusion is large. If there is, in step S605, a magnification (magnification) magnification of (set paper size (print size of recording paper with respect to original size)) × 1.1 is selected.
[0086]
Here, the setting of these scaling factors will be described.
[0087]
In the present embodiment, the magnification is set to 1.1 times when the amount of protrusion set by the user is large, and 1.05 times when the amount of protrusion is small.
[0088]
For example, when the set magnification (recording paper print size with respect to the document size) is 100%, and when the amount of protrusion is small, 100% is multiplied by 1.05 and the enlargement ratio is 105%. Or, when the protruding amount is large, the enlargement ratio is 110% by multiplying 100% by 1.1.
[0089]
These magnifications are determined on the assumption of the following uses.
[0090]
First, 1.1 times the large amount of protrusion is an enlargement ratio suitable for borderless copying of an L-size original having margins onto an L-size recording sheet, and setting the enlargement ratio to 1.1 times with a margin. I have.
[0091]
Further, 1.05 times the small amount of protrusion is an enlargement ratio suitable for copying an A4 document onto the recording paper A4. If the enlargement ratio is further reduced, the recording paper is skewed due to mechanical accuracy or the like. If it does, borderless copying may not be possible, so the setting is 1.05 times.
[0092]
It is to be noted that the above-mentioned values of the magnification are merely examples, and it is needless to say that the values are not necessarily limited because they vary depending on the mechanical structure and characteristics of the apparatus.
[0093]
After the scaling factor is determined in step S603 or S605, in the subsequent step S604 or step S606, when the scaling factor is determined based on the set scaling factor (recording paper print size with respect to the document size) and the amount of protrusion, respectively, + ”. For example, if the set magnification (recording paper size with respect to the document size) is 100%, “100% +” is displayed. Of course, here, the specific numerical value of the magnification determined as 105% or 110% may be displayed, but the specific numerical value of the magnification such as “100% +” may not be displayed. This will not unnecessarily confuse the user. The monitor display method that does not display a specific magnification value such as “100% +” matches well with the setting method of the present embodiment in which the amount of protrusion is set as “large” or “small”. The usability of the device becomes more natural. However, the monitor display format of the determined magnification may be arbitrary as long as the current magnification can be appropriately notified to the user, and may be appropriately changed by those skilled in the art.
[0094]
The recording paper size (strictly speaking, the effective recording size of the recording paper) relative to the document size, that is, the set magnification can be detected by an appropriate method. For example, the document size can be detected by pre-scanning as in the case of other copies, or a method in which a user manually inputs the size using an appropriate user interface may be used. The recording paper size can be detected by a suitable sensor provided in a recording paper cassette or the like, and this may also be manually input by a user through an explicit operation. When the document size and the recording paper size are known, the relative magnification of the two can be calculated from the ratio of the two, that is, the above-mentioned set magnification can be calculated (or a user interface in which the user directly selects this set magnification by manual operation is also available). Conceivable).
[0095]
In the actual borderless copy processing in step S607, processing as shown in FIGS. 7 and 8 is performed.
[0096]
FIG. 7A shows a reading range 71 of a marginal copy for comparison. In the case of a marginal copy, as shown in FIG. 7A, the upper, lower, left and right are masked by 2 mm, 5 mm, 2.6 mm, and 1 mm, respectively (this range is not read from the image sensor 1806).
[0097]
On the other hand, the reading range 72 of the borderless copy is as shown in FIG. 7B. In this case, the original image is read in full size (full surface reading) without masking the image read by the image sensor 1806.
[0098]
Then, the image is enlarged by the magnification determined in step S603 or S605 as shown in FIG. Reference numeral 81 in FIG. 8A indicates a portion enlarged by this enlargement processing. Further, a centering process is performed so that a central portion of the enlarged image 81 can be output as shown in FIG. The output range after the centering processing is 82, and the image range 83 is not output.
[0099]
By performing the centering processing as shown in FIG. 8B, it is possible to prevent the occurrence of uneven margins around the recording paper even if there is some error in the reading system and the recording system.
[0100]
The image enlarged as shown in FIG. 8B is sent to the printer engine, and a borderless image (or an image having a margin smaller than a predetermined value, even if there is a margin) is output on a recording sheet.
[0101]
According to the above-described embodiment, although the copy mode (copy type) that requires full-surface reading (or pre-scan is required) is selected, an inappropriate ADF reading method is selected. In such a case, error processing is performed, and the user is notified of the error processing so as not to perform the copy processing. Therefore, the user forcibly copies using an inappropriate reading method, and a copy different from the intended one is performed. Can be prevented beforehand.
[0102]
Also, in a marginless copy in which an original image that has been read over the entire surface is enlarged at a predetermined magnification and recorded on recording paper, the amount of protrusion, that is, of an image that protrudes from the recording paper and becomes non-recording due to the enlargement of the original image. Only by setting the protrusion amount corresponding to the size, the magnification for enlargement is automatically determined, and borderless copying can be executed without failure.
[0103]
In particular, the user only has to perform an operation for setting the amount of protrusion, for example, (a) a setting operation for increasing the amount of protrusion, and (b) a setting operation for decreasing the amount of protrusion, and setting the magnification (original size: relative magnification of the recording paper size), Since it is not easy to imagine as in the case of inputting the numerical value of the magnification, and it is not necessary to perform a setting operation that requires skill in the setting operation, borderless copying can be executed very easily without failure.

【The invention's effect】
As is apparent from the above description, according to the present invention, the original image is recorded on the recording paper in the borderless copy mode in which the image read from the entire surface of the original by the image reading means is enlarged at a predetermined magnification and recorded on the recording paper. In the image processing apparatus, the control method thereof, and the control program, the user sets the amount of protrusion that corresponds to the size of an image that protrudes from the recording paper and becomes non-recorded by enlarging the document image. Based on the protruding amount, the configuration is adopted in which the magnification is determined at the time of the enlargement, so that the user only has to set the protruding amount corresponding to the size of the image that protrudes and becomes non-recorded, and The magnification ratio for enlargement is automatically determined without errors, making it difficult to image like input, and without requiring setting operations that require skill in setting operations. It is possible to execute the copy, there is excellent effect that.
