Description

  The present invention relates to an image forming apparatus capable of forming a mirror image and an image reading apparatus capable of reading a mirror image.

  In some cases, it is required to process a certain input document while comparing the corresponding converted document. For example, when performing a proofreading process, it is efficient to work while simultaneously referring to a manuscript (input document) and a proofreading symbol (converted document) added to the manuscript. Alternatively, when performing the translation process, it is efficient to perform the work while simultaneously referring to the original sentence (input document) and the translated sentence (converted document) generated from the original sentence.

When creating a converted document, the user often writes the converted document by hand on an input document printed on paper. In this case, in order to electronically process the input document and the converted document, it is necessary to separate and extract the converted document from the input document. As a technique for separating and extracting a converted document from a converted document written on an input document, for example, there are techniques described in Patent Documents 1 and 2. Patent Documents 1 and 2 disclose a technique for electronically extracting a calibration result added in red or the like on a printed document and displaying the calibration result on a display to accurately convey the calibration result to the user. ing.

The mirror image conversion unit 33 generates image data indicating a mirror image of the input image.

  FIG. 2 is a diagram illustrating a hardware configuration of the multifunction peripheral 100. The multifunction peripheral 100 mainly includes a control system including a CPU (Central Processing Unit) 110 and the like, an image reading system 160 that reads an image of a document, and an image forming system 170 that forms an image on a sheet (recording material). The CPU 110 has a function of controlling each component of the multifunction peripheral 100 by reading and executing a control program stored in the storage unit 120. The storage unit 120 includes a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), etc., and various programs such as a control program and a translation program, and various data such as image data and text data. Remember. The display unit 130 and the operation unit 140 are user interfaces. The display unit 130 is configured by, for example, a liquid crystal display, and displays a message to the user, an image showing a work status, and the like according to a control signal from the CPU 110. The operation unit 140 includes a numeric keypad, a start button, a stop button, a touch panel installed on a liquid crystal display, and the like, and outputs a signal corresponding to a user operation input and a display screen at that time. The user can input an instruction to the multifunction device 100 by operating the operation unit 140 while viewing an image or message displayed on the display unit 130.

  The I / F 150 is an interface for transmitting and receiving control signals and data to and from other devices. By connecting to a public telephone line, for example, via the I / F 150, the multi-function device 100 can perform FAX transmission / reception. Alternatively, electronic mail messages can be transmitted and received by connecting to a network such as the Internet via the I / F 150.

  The image reading system 160 includes a document conveying unit 161 that conveys a document to a reading position, an image reading unit 162 that reads an original at the reading position and generates an analog image signal, and converts the analog image signal into digital image data. An image processing unit 163 that performs various image processing. The document feeder 161 is a document feeder such as an ADF (Automatic Document Feeder). The image reading unit 162 includes a platen glass on which an original is placed, an optical device such as a light source and a CCD (Charge Coupled Device) sensor, and an optical system such as a lens and a mirror (all not shown).

<2. Operation>
Next, operations related to functions characteristic of the present invention among the functions of the multifunction peripheral 100 will be described. The operation of the multifunction peripheral 100 is mainly classified into an operation of forming a mirror image on a sheet and an operation of reading a document on which the mirror image is printed and processing the read image. The operation of forming a mirror image is further divided into an aspect in which image formation is performed on both sides of the recording material and an aspect in which image formation is performed only on one surface of the recording material. Hereinafter, each operation will be described.

<2-1. Mirror image formation>
<2-1-1. Double-sided image formation>
First, a mode in which a normal image is formed on one side of a sheet and a mirror image is formed on the back side thereof will be described. This aspect is further roughly divided into an aspect in which the converted document is a mirror image document (Example 1) and an aspect in which the input document is a mirror image document (Example 2).

(Example 1)
FIG. 3 is a flowchart illustrating the image forming operation of the multifunction peripheral 100. FIG. 4 is a diagram showing a document D to be processed in the present embodiment. In the present embodiment, the MFP 100 performs translation on the input document D _IN to which a data of reading the document D (conversion), to generate the converted document D _T (Figure 4 (b)). Next, the multi-function device 100 mirrors the converted document DT to generate a mirror image document D _T ^m (FIG. 4C). Then, the MFP 100, the input document D _IN on the surface of the sheet to the image forming mirror images document D _T ^m on the back surface (FIG. 4 (d)). The operation will be described below with reference to FIG.

  When the power (not shown) is turned on, the CPU 110 of the multifunction peripheral 100 reads the control program from the storage unit 120 and executes it. By executing the control program, the CPU 110 controls the display unit 130 and causes the display unit 130 to display a menu screen. The user sets the document D to be processed on the ADF or the platen glass. The user operates the operation unit 140 while looking at the menu screen displayed on the display unit 130, thereby causing the multifunction peripheral 100 to display the document D (original text) on the front surface of the paper and the translated text of the document D (for example, on the back surface). , English translation) is input as a mirror image.

When the instruction of the mirror image formation is input, CPU 110 reads a document D controls the image reading system 160, to generate image data of the input document D _IN (step S110). The CPU 110 stores the generated image data in the storage unit 120. Then CPU110 performs the character recognition process on the input document D _IN (step S120). Specifically, it is as follows. CPU 110 reads the character recognition program from storage unit 120 and executes it. When executing a character recognition program, CPU 110 first performs a layout extraction processing on the input document D _IN, into a plurality of small regions on the basis of the input document D _IN in the layout. CPU110 performs a character recognition process for every small area | region, and produces | generates original text data. The CPU 110 measures the character size for each small area. The CPU 110 stores the original text data, the measured character size, coordinate parameters indicating the position and size of the small area as layout information, and the small area identifier for specifying the small area in the storage unit 120.

  Next, the CPU 110 translates the original sentence and generates a translated sentence (step S130). Specifically, it is as follows. The CPU 110 reads the translation program from the storage unit 120 and executes it. When the translation program is executed, the CPU 110 translates the original text data into a language (for example, English) designated by the user's instruction input, and generates translated text data. The CPU 110 stores the generated translated text data, the original text character size, the coordinate parameter, and the small area identifier in association with each other in the storage unit 120. Note that, for example, a portion that does not change before and after the translation processing, such as the illustration portion of FIG. 4, may not be included in the converted document.

Next, the CPU 110 generates translated sentence image data from the translated sentence text data (step S140). Specifically, it is as follows. CPU110 produces | generates the image data which consists of a character of the same size as the character size matched with the translation text data from translation text data. The size of the image data is defined by coordinate parameters. Note that the length (number of characters) of the translated sentence does not necessarily match the length of the original sentence. Therefore, when the translated text does not fit within the designated small area, the character size may be reduced as compared with the original text. When there are a plurality of small areas, the CPU 110 performs this process for each small area. When the processing is completed for all the small areas, the CPU 110 combines the image data of the small areas and generates the image data of the converted document _DT having the same size as the input document _DIN . At this time, it is desirable that each small area is shifted from the position of the small area in the original text by the character size. By arranging the small area of the translated sentence in this way, the translated sentence is positioned one line below the position where the original sentence was located in the converted document _DT (FIG. 4B). That is, the words of the input document D _IN, sentences, paragraphs or the position of the sentence, the word transfer document D _T corresponding thereto, sentences, paragraphs or the position of the text, are shifted by a predetermined amount.

  The positional relationship between the position of the word, sentence, paragraph, or sentence of the input document and the position of the word, sentence, paragraph, or sentence of the corresponding converted document is not limited to that described above. For example, the input document and the corresponding converted document may be formed at the same position. Alternatively, the margin portion of the input document may be detected by layout extraction, and the converted document may be arranged in the margin portion.

Next, the CPU 110 generates image data of the mirror image document D _T ^m from the image data of the converted document D _T (step S150). FIG. 5 is a diagram for explaining a method of forming a mirror image. As shown in FIG. 5A, the CPU 110 reads the image data of the converted document _DT from the left one line and stores it in a FILO (First In Last Out) format buffer. When the data for one line is stored in the FILO, the CPU 110 sequentially reads the data from the FILO and stores it in the storage unit 120 as image data of the mirror image document D _T ^m . In this way, in the mirror image document D _T ^m , the data for one line is arranged horizontally reversed (FIG. 5B). When the processing is completed for all the lines of the image data of the converted document D _T, the image data of the mirror image document D _T ^m is generated (FIG. 4C).

Next, CPU 110 controls the image forming system 170 images the input document D _IN on the surface of the sheet to form an image of the mirror image document D _T ^m on the back surface (step S160). FIG. 4D is a diagram showing the image thus formed on the sheet. If the surface image is viewed normally, the user can see the original text. When the paper is seen through the light, the image on the back can be seen through. Since the mirror image document D _T ^m is formed on the back surface, the input document D _IN and the converted document D _T appear to overlap when viewed through the front surface. In the present embodiment, since the translated sentence is formed one line below the original sentence, the translated sentence can be seen through between the lines of the original sentence.

When forming an image, the density and / or saturation of a document other than the mirror image document D _T ^m (in this case, the input document D _IN ) is relatively lowered as compared to the input document. Is desirable. Since the image formed on the back surface is viewed from the front through the paper, if the front surface and the back surface are formed with the same density or saturation, the image formed on the back surface looks thin. If the image formed on the back surface is formed to be relatively dark, the image on the front surface and the image on the back surface have the same density or saturation and are easier to see.

  The document created as described above is suitable for learning such as language learning. The user can confirm the answer by reading the original sentence (question sentence) written in Japanese, for example, and considering the translated sentence (answer), and seeing the translated sentence (correct answer) through the paper.

  The document conversion process is not limited to translation, and various processes can be considered. For example, it is possible to insert a proofreading symbol, correct a document, or insert a description (footnote) of a specific phrase. For example, by forming a document before proofreading on the front surface and a mirror image of the proofreading symbol on the backside, the user can compare the document before proofreading with the proofreading symbol. Alternatively, the user can compare the uncorrected document with the corrected document by forming the uncorrected document on the front side of the paper and forming a mirror image of the corrected document on the back side of the paper.

(Example 2)
FIG. 6 is a diagram showing a document D to be processed in the present embodiment. In Example 1 above, the input document D _IN to the surface, has been described manner to form a mirror image document D _T ^m of transfer document D _T to the rear surface, in the example shown in FIG. 6, converted into surface document D _T ( FIG. 6B shows an aspect of forming a mirror image document D _IN ^m (FIG. 6C) of the input document D _IN (FIG. 6A) on the back side.

FIG. 6D shows an image formed on the paper in this way. If the surface image is viewed normally, the user can see the translation. When the paper is seen through the light, the image on the back can be seen through. Since the mirror image document D _IN ^m is formed on the back surface, the input document D _IN and the converted document _DT appear to overlap each other when viewed through the front surface. Since the translated sentence is formed one line below the original sentence, the translated sentence can be seen through between the lines of the original sentence. The operation of the multifunction device 100 is basically the same as that of Example 1 except that the images formed on the front and back sides of the sheet are interchanged, and thus the description thereof is omitted.

<2-1-2. Single-sided image formation>
FIG. 7 is a diagram showing a document D to be processed in the present embodiment. In the present embodiment, a mirror image document D _IN ^m (FIG. 7B) generated from the input document D _IN (FIG. 7A) is formed on the back side of the sheet. No image is formed on the surface of the paper. Therefore, nothing is visible when viewed normally from the surface of the paper. However, when the see through by such shed light from the back, the input document D _IN is visible. Since the method for forming a mirror image is the same as that for forming images on both sides, the description thereof is omitted.

The mirror image document formed in this way is suitable for proofreading, for example. For example, a sheet on which a mirror image document D _IN ^m (FIG. 7B) is formed is placed on a table composed of a light source and a light transmitting plate with the front side facing up. Seen through the input document D _IN to this. The user writes proof symbols for documents on this table. In this way, only the calibration symbol is drawn on the surface of the paper. If the surface is read with a scanner or the like, only the calibration symbol can be read. So-called annotations such as proofreading symbols are often difficult to separate from the original document. However, if a mirror image document is used in this way, only the annotation (calibration symbol) is drawn on the surface of the paper, so that the annotation can be easily extracted.

<2-2. Reading mirror image>
Next, a mode in which a document in which an annotation (proofreading symbol) is added to the front surface of a paper having a mirror image formed on the back surface as shown in FIG.

  FIG. 8 is a diagram showing the image reading system 1 according to the present embodiment. The image reading system 1 includes a multifunction device 100 and a PC 200 connected to the multifunction device 100 via a network 300. CPU 210 executes a program stored in ROM 230 or HDD 240 using RAM 220 as a work area. The user can input instructions to the PC 200 by operating the keyboard 250 and the mouse 260. The display 270 displays the progress of the program and a message to the user under the control of the CPU 210. The PC 200 is connected to the multifunction device 100 via the I / F 280, and can send and receive data to and from the multifunction device 100. These components are connected to each other by a bus 290.

  FIG. 9 is a flowchart showing the calibration process according to the present embodiment. The multi-function device 100 forms a mirror image document on the back side of the paper in the same manner as described above (step S200). The user enters a calibration symbol on the front surface of the paper while irradiating light from the back side of the paper to watermark the mirror image document (step S210). FIG. 10 is a diagram illustrating configuration symbols (annotations) added to a mirror image document. FIG. 10A is a view of a state where a mirror image formed on the back surface is watermarked as viewed from the front surface. FIG. 10B is a diagram illustrating a state in which annotations are added to the surface of the document illustrated in FIG. Actually, only the annotation is described on the surface of the sheet as shown in FIG.

  A description will be given with reference to FIG. 9 again. The multi-function device 100 reads a document (step S220). That is, the user sets a manuscript (a mirror image document in which a calibration symbol is written) on the platen glass or ADF, and presses the start button of the operation unit 140. The CPU 110 controls the image reading system 160 to read an image, and generates image data for each of the front surface and the back surface.

  Next, the CPU 110 specifies the mirror image surface on which the mirror image is printed (step S230). The mirror image plane is specified as follows, for example. In the mirror image document, a mirror image plane identification figure (for example, a barcode, a specific figure, a specific character string, etc.) indicating that the surface is a mirror image plane is described in advance. The storage unit 120 stores image data of a mirror image plane identification figure in advance. The CPU 110 performs matching between the image data on the front and back sides of the paper and the mirror image identification figure. The CPU 110 identifies the image data that includes the mirror image identification graphic among the image data of the front surface and the back surface as the mirror image surface.

  The specification of the mirror image plane is not limited to the method described above, and may be performed as follows. For example, the CPU 110 generates each mirror image data from the front and back image data. The CPU 110 performs character recognition processing on the generated mirror image data on the front and back surfaces, and calculates a character recognition rate. If the original mirror image is further mirror-transformed, it should return to a normal image. Therefore, the CPU 110 identifies the image data with the higher character recognition rate as the mirror image plane. Alternatively, when the document is set on the platen glass or ADF, rules such as lowering the mirror image plane may be determined in advance, and the CPU 110 may specify the mirror image plane according to the rule. Alternatively, when the user instructs to read an image, it may be input which of the front surface and the back surface is a mirror image surface.

  Next, the CPU 110 extracts annotations (step S240). The CPU 110 specifies image data other than the image data specified to be a mirror image plane (surface image data in the present embodiment) as annotation image data.

  Next, the CPU 110 performs calibration processing (step S250). The calibration process is performed as follows, for example. The CPU 110 performs mirror image conversion on the image data identified as the mirror image plane, and generates a mirror image of the mirror image plane. The mirror image on the mirror image plane is the same as the input image (FIG. 7A in this embodiment). The CPU 110 stores image data (normal input document image) generated by mirror image conversion in the storage unit 120. The CPU 110 further performs character recognition processing on the image data of the input document to generate text data and text data layout information. CPU 110 stores the generated text data and layout information in storage unit 120.

  Next, the CPU 110 performs a layout extraction process on the annotation image data and separates the annotation into elements one by one. The CPU 110 stores the image data of the separated annotation in association with the coordinate data indicating the position of the annotation in the storage unit 120. The CPU 110 transmits text data of the input document, layout information, separated annotation image data, and coordinate data indicating the position of the annotation to the PC 200 via the I / F 150.

  Upon receiving these data, the CPU 210 of the PC 200 stores the received data in the HDD 240. The CPU 210 reads the calibration program from the HDD 240 and executes it. When the proofreading program is executed, the CPU 210 generates image data from the text data and layout information of the input document. The CPU 210 controls the display 270 according to the generated image data to display an input image. Further, the CPU 210 displays the annotation on the screen by an instruction input via the user's keyboard 250, mouse 260, and the like. The annotation is displayed on the character with the annotation according to the coordinate data. The user corrects the text while viewing the image with the annotation. The CPU 210 stores the corrected text data in the HDD 240 in accordance with a user operation input.

  FIG. 11 is a diagram illustrating the document after the proofreading process performed as described above. In the above-described embodiment, the aspect in which the calibration process is performed in the PC 200 has been described. However, the multifunction apparatus 100 may perform the calibration process.
