The mode switching unit 57 switches the reading mode input from the mode setting unit 53 when the automatic switching flag is set to ON, but the mode switching unit 57 switches the reading mode input from the mode setting unit 53, but the mode switching unit 57 switches the reading mode when the automatic switching flag is set to OFF. Do not switch the read mode. The automatic switching flag may be set in advance by the administrator who manages the MFP 100, or may be set by the user who operates the MFP 100. The mode switching unit 57 includes an image quality detection unit 81 and a document number detection unit 83.

The image quality detection unit 81 detects the image quality set under the reading conditions input from the condition setting unit 55. For example, when the degree of image quality can be set in three stages as a reading condition, which of the three stages is set is detected. For example, it may be possible to set in descending order of the degree of image quality in three stages of a photograph, a photograph / character, and a character. In this case, the degree of image quality is higher in the order of a photograph and a photograph / character. Further, the degree of image quality may be a resolution or / and a number of colors, not a photograph, a photograph / character, or a reading condition of a character. The higher the resolution, the higher the degree of image quality. The number of colors as a reading condition is set to either color or monochrome. Color has a higher degree of image quality than monochrome.

In the mode switching unit 57, when the automatic switching flag is set to ON and the reading mode is set to the first mode, the condition indicating the degree of image quality by the image quality detecting unit 81 is equal to or higher than a predetermined degree. In some cases, the reading mode is switched to the second mode. The higher the degree of image quality, the larger the amount of image data that the document reading unit 130 reads and outputs the document. Therefore, the higher the degree of image quality, the longer the time for the document reading unit 130 to read the document. Further, the larger the amount of image data, the greater the load on the CPU 111 for processing the image data. Therefore, for example, the time for the CPU 111 to store the image data in the HDD 115 or the time for transmitting the image data from the communication I / F unit 112 to the outside becomes long.

In the reading conditions, the image type, resolution, and number of colors are included as settings indicating the degree of image quality. As an example of the image type, a case where there are three image type setting values, a photograph, a photograph / character, and a character, will be described as an example. The image data in which the photograph is set as the set value includes the image of the photograph. The image data in which a photograph / character is set as a set value includes an image of a photograph and an image of characters. The image data in which characters are set in the set value includes an image of characters. The image quality is higher in the order of photo, photo / text, and text. When the photo / character setting value is set as the threshold value, the mode switching unit 57 sets the reading mode to the second mode when the photo or photo / character is set as the image type in the reading condition. Switch.

The higher the resolution, the higher the degree of image quality. The resolution here is the number of pixels per predetermined length. The mode switching unit 57 switches the reading mode to the second mode when the resolution is equal to or higher than a predetermined value.

Further, the larger the number of colors, the higher the degree of image quality. As an example of the setting value of the number of colors, a case where there are two, full color and monochrome, will be described as an example. The higher the number of colors, the higher the degree of image quality. Full color has more colors than monochrome. The mode switching unit 58 switches the reading mode to the second mode when the set value of the number of colors is full color.

The document number detection unit 83 detects the number of documents to be read. For example, the number of documents is detected from the height detected by the sensor that detects the height of the documents placed on the document tray of the automatic document transfer device 120. The thickness per original is registered in advance, and the number of originals is calculated from the height detected by the sensor and the thickness of the original.

The mode switching unit 57 switches the scanning mode to the first mode when the scanning mode is set to the second mode and the number of documents detected by the document sheet detecting unit 83 is equal to or greater than a predetermined value. As the number of originals increases, the amount of image data data increases. Therefore, when the number of originals is a predetermined value or more, the amount of image data data is reduced as much as possible.

When switching the reading mode input from the mode setting unit 53, the mode switching unit 57 outputs the reading mode after the switching to the reading control unit 59 and does not switch the reading mode input from the mode setting unit 53. In this case, the reading mode input from the mode setting unit 53 is output to the reading control unit 59.

In the read control unit 59, the read mode is input from the mode switching unit 57, and the read mode is input from the condition setting unit 55. When the scanning mode is the first mode, the scanning control unit 59 controls the document scanning unit 130 to scan the document according to the scanning conditions input from the condition setting unit 55. Since the document reading unit 130 reads the document and outputs the image data, the reading control unit 59 stores the image data in a folder specified by the reading condition among the plurality of folders of the HDD 115, and at the time of storage. The file name of the image data is output to the generation unit 61. Further, when the scanning mode is the second mode, the scanning control unit 59 controls the document scanning unit 130 to scan the document according to a predetermined maximum scanning condition instead of the scanning condition input from the condition setting unit 55. Let me. Since the document reading unit 130 reads the document and outputs the image data, the reading control unit 59 stores the image data in a folder specified by the reading condition among the plurality of folders of the HDD 115, and at the time of storage. The file name of the image data is output to the generation unit 61. The maximum scanning condition is a condition in which a photograph is set in the setting value of the image type among the scanning conditions, a condition in which the maximum resolution is set in the setting value for determining the resolution, and a color is set in the setting value of the number of colors. It is a condition.

Among the plurality of folders included in the HDD 115, some have conversion conditions set. The conversion conditions at least define the folder identification information that identifies any of the plurality of folders that the HDD 115 has, and the image quality of the image data. When the file name is input from the read control unit 59, the storage generation unit 61 determines whether or not the conversion condition is set in the folder in which the image data of the file name is stored. When the conversion condition is set in the folder in which the image data of the file name input from the read control unit 59 is stored, the storage generation unit 61 converts the image data into the first converted image having the image quality determined by the conversion condition. It is converted into data, and the first converted image data is stored in a folder specified by the folder identification information defined by the conversion conditions. Here, the folder specified by the folder identification information defined by the conversion conditions is a shared folder to which the authority to access each of a plurality of users is given. The folder specified by the folder identification information defined in the conversion conditions is not limited to the shared folder, and may be a personal folder to which a specific user is authorized to access.

The output condition acquisition unit 67 acquires the output condition. The output condition acquisition unit 67 acquires the output condition input from the operation reception unit 51, and outputs the acquired output condition to the output unit 63 and the image quality conversion unit 65. The output condition includes a setting for specifying the image data to be output, a setting for specifying the image quality of the image data, and a setting for specifying the output destination of the image data to be output.

The image quality conversion unit 65 specifies the image data to be output according to the input of the output condition. When the conversion condition is set in the folder in which the specified image data is stored, the image quality conversion unit 65 specifies the first converted image data corresponding to the image data. The image quality conversion unit 65 compares the image quality specified by the output condition with the image quality of the first converted image data, and outputs the image data when the image quality specified by the output condition is different from the image quality of the first converted image data. It is converted into the second converted image data of the image quality specified by the condition. The image quality conversion unit 65 outputs the second converted image data to the output unit 63.

The output unit 63 specifies the data to be output according to the input of the output condition. The output unit 63 identifies the image data set in the output condition, and determines whether or not the conversion condition is set in the folder in which the specified image data is stored. When the conversion condition is set in the folder in which the image data is stored, the output unit 63 specifies the first converted image data corresponding to the image data. The output unit 63 compares the image quality specified by the output condition with the image quality of the first converted image data. The output unit 63 determines the image quality specified by the output conditions and the image quality of the first converted image data, and if they match, the first converted image data is determined as the output target, but if they are different, the first conversion image data is determined. 2 Determine the converted image data as the output target. If the conversion condition is not set in the folder in which the image data is stored, the output unit 63 generates the conversion condition based on the output condition and sets the conversion condition in the folder in which the image data is stored. .. This makes it possible to omit the operation of setting conversion conditions in the folder.

When the image data format is set in the output condition, the image quality conversion unit 65 compares the format and image quality specified by the output condition with the format and image quality of each of the first converted image data, and outputs the data. When the format and image quality specified by the conditions are different from any of the formats and image quality of the first converted image data, the image data is converted into the second converted image data of the format and image quality specified by the output conditions. Further, when the format of the image data is set in the output condition, the output unit 63 compares the format and the image quality specified by the output condition with the format and the image quality of the first converted image data. The output unit 63 compares the format and image quality specified by the output conditions with the format and image quality of the first converted image data, and if they match, determines the first converted image data as the output target. If the two are different, the second converted image data is determined as the output target.

The output unit 63 includes a first output unit 85 and a second output unit 87. When the first converted image data is determined to be the output target, the first output unit 85 outputs the first converted image data to the output destination set in the output condition. For example, if the output condition is that an e-mail address is set as the output destination, an e-mail with the e-mail address set as the destination, the first converted image data set in the attached file is generated, and the generated e-mail is generated. , The communication I / F unit 112 is controlled and transmitted to the e-mail server. Further, when the network address of the external computer is set as the destination, the communication I / F unit 112 is controlled to transmit the first converted image data to the external computer. For example, the communication I / F unit 112 is controlled according to FTP (File Transfer Protocol) to transmit the first converted image data.

When the second converted image data is determined to be the output target, the second output unit 87 outputs the second converted image data to the output destination set in the output condition. For example, if the output condition is that an e-mail address is set as the output destination, an e-mail with the e-mail address set as the destination and the second conversion image data set in the attached file is generated, and the generated e-mail is generated. , The communication I / F unit 112 is controlled and transmitted to the e-mail server. Further, when the network address of the external computer is set as the destination, the communication I / F unit 112 is controlled to transmit the second converted image data to the external computer.

FIG. 4 is a flowchart showing an example of the flow of the document reading process. The document reading process is a process executed by the CPU 111 when the CPU 111 included in the MFP 100 executes a document reading program stored in the ROM 113, HDD 115, and CD-ROM 118. With reference to FIG. 4, the CPU 111 accepts the reading condition (step S01). When the user inputs the reading condition to the operation unit 163, the reading condition input to the operation unit 163 is accepted. Further, when the user inputs an operation for specifying one of a plurality of folders of the HDD 115 as the storage destination of the image data to the operation unit 163, the user associates the image data with the folder specified by the operation accepted by the operation unit 163. Acquire the read condition.

In the next step S02, the read mode setting process is executed, and the process proceeds to step S03. The details of the reading mode setting process will be described later, but it is a process of setting the reading mode to either the first mode or the second mode. In the next step S03, the process is branched according to the read mode. If the reading mode is the first mode, the process proceeds to step S04, and if the reading mode is the second mode, the process proceeds to step S05.

In step S04, the document reading unit 130 is controlled to read the document according to the scanning conditions accepted in step S01, and the process proceeds to step S06. In step S05, the document reading unit 130 is controlled to read the document according to the maximum scanning conditions, and the process proceeds to step S06. In step S06, the image data output by the document reading unit 130 is stored in the folder specified by the reading condition among the plurality of folders included in the HDD 115, and the process proceeds to step S07. In step S07, the reading condition is associated with the image data, and the process proceeds to step S08. When step S04 is executed, the reading condition accepted in step S01 is associated with the image data, and when step S05 is executed, the maximum reading condition is associated with the image data.

In step S08, it is determined whether or not the conversion command is set in the folder in which the image data is stored in step S06. If the conversion command is set, the process proceeds to step S09, but if not, the process ends. In step S09, the image data is processed, the image processing defined by the conversion conditions is executed, and the processing proceeds to step S10. The image processing is a process of changing the image quality of image data, and includes, for example, a process of changing an image type, a process of changing a resolution, and a process of changing the number of colors. Further, the image processing may include processing corresponding to each type of image. For example, it is a smoothing process for smoothing a change in brightness for a photographic image, and an edge enhancement process for emphasizing an edge for a character image. The image processing is not limited to the processing of changing the image type, the processing of converting the resolution, the processing of converting the number of colors, and the processing corresponding to each of the image types, and may include other processing. .. In step S10, the image data after the image processing is converted into the first converted image data in the format defined by the conversion conditions, and the processing proceeds to step S11. The format includes, for example, the format of the data after the compression process. The compression process includes a lossless compression process and a lossy compression process.

In step S11, the first converted image data is stored in the shared folder, and the process ends. A shared folder is a folder defined by a conversion command. A shared folder is a folder accessible to one or more users authorized to operate the MFP 100. The folder defined by the conversion command is not limited to the shared folder, and may be any of a plurality of folders possessed by the HDD 115, and is predetermined in order to store the image data read by the document reading unit 130. It may be a folder, or it may be a folder assigned to an individual.

FIG. 5 is a flowchart showing an example of the flow of the reading mode setting process. The read mode setting process is a process executed in step S02 of FIG. Before the reading condition setting process is executed, either the reading condition input by the user or the reading condition set in the folder is determined. With reference to FIG. 5, it is determined whether or not the temporary change flag is set to ON (step S21). If the temporary change flag is set to ON, the process proceeds to step S22, but if not, the process proceeds to step S25. The temporary change flag is a flag preset by the administrator who manages the MFP 100. Further, the temporary change flag may be set by the user who operates the MFP 100.

In step S22, the reading mode input by the user to the operation unit 163 is accepted, and the process is branched according to the accepted reading mode. If the accepted read mode is the first mode, the process proceeds to step S23, but if the accepted read mode is the second mode, the process proceeds to step S24. In step S23, the reading mode is determined to be the first mode and the process proceeds to step S28, and in step S24, the reading mode is determined to be the second mode and the process proceeds to step S28.

In step S25, the process is branched according to the reading mode set in the folder specified by the reading condition. If the reading mode set in the folder is the first mode, the process proceeds to step S26, but if the reading mode set in the folder is the second mode, the process proceeds to step S27. In step S26, the reading mode is determined to be the first mode and the process proceeds to step S28, and in step S27, the reading mode is determined to be the second mode and the process proceeds to step S28.

In step S28, it is determined whether or not the automatic switching flag is set to ON. If the automatic switching flag is set to ON, the process proceeds to step S29, but if not, the process returns to the document scanning process. The automatic switching flag may be set in advance by the administrator who manages the MFP 100, or may be set by the user who operates the MFP 100.

In step S29, it is determined whether or not the number of originals is equal to or greater than the predetermined number. If the number of originals is equal to or greater than the predetermined number, the process proceeds to step S32, otherwise the process proceeds to step S30. In step S30, it is determined whether or not the condition indicating the degree of image quality in the reading condition is set to a predetermined image quality or higher. If the degree of image quality is a photo / text setting or a photo setting, if the resolution is set to a predetermined value or higher, or if the number of colors is a color setting, the process proceeds to step S31, but otherwise. If the process proceeds to step S32. In step S31, the scanning mode is determined to be the second mode, and the processing is returned to the document scanning processing. In other words, when the reading mode is determined to be the first mode, the mode is switched to the second mode. In step S32, the scanning mode is determined to be the first mode, and the processing is returned to the document scanning processing. In other words, when the reading mode is determined to be the second mode, the mode is switched to the first mode. As a condition indicating the degree of image quality in the reading condition, it is determined whether or not the image type is a character, and if the image type is a character, the process proceeds to step S32, and if not, the process is performed. You may proceed to step S31.

FIG. 6 is a flowchart showing an example of the flow of the BOX transmission process. The BOX transmission process is a process executed by the CPU 111 when the CPU 111 included in the MFP 100 executes the BOX transmission program stored in the ROM 113, the HDD 115, and the CD-ROM 118. The BOX transmission program is a part of the document reading program. With reference to FIG. 6, the CPU 111 accepts the output condition (step S51) and proceeds to the process in step S52. Accepts the output conditions that the user inputs to the operation unit 163. The output condition includes a setting for specifying the image data to be output, a setting for specifying the image quality of the image data, and a setting for specifying the output destination of the image data to be output.

In step S52, the reading condition associated with the image data specified by the output condition is acquired, and the process proceeds to step S53. In step S53, the output condition and the reading condition are compared, and the process proceeds to step S54. In step S54, it is determined whether or not the image quality determined by the output condition and the image quality determined by the reading condition are the same. If they are the same, the process proceeds to step S55, otherwise the process proceeds to step S58.

In step S55, it is determined whether or not the format defined by the output condition and the format defined by the reading condition are the same. If the format is the same for the output condition and the read condition, the process proceeds to step S56, but if not, the process proceeds to step S58. In step S56, it is determined whether or not the first converted image data corresponding to the image data exists in the shared folder. If the first converted image data exists, the process proceeds to step S57, but if it does not exist, the process proceeds to step S58. In step S57, the first converted image data is transmitted to the output destination set in the output condition, and the process is terminated. If an e-mail address is set according to the output conditions, set the e-mail address set according to the output conditions to the destination, generate an e-mail containing the first converted image data, and send the e-mail to the e-mail server. Send to. If the image quality and format of the first converted image data are the same as the image quality and format set in the output conditions, the first converted image data is transmitted, and if either one is different, the process proceeds to step S58. To.

In step S58, conversion conditions are set in the folder in which the image data is stored based on the output conditions, and the process proceeds to step S59. As a result, the conversion conditions are set in the folder in which the image data is stored, so that the operation of setting the conversion conditions becomes unnecessary. In step S59, the image data set as the output target under the output conditions is read from the HDD 115, and the process proceeds to step S60. In step S60, the image data is image-processed so that the image quality is set by the output condition, and the processing proceeds to step S61. In step S61, the image data is converted into the second converted image data in the format set by the output condition, and the process proceeds to step S62. In step S62, the second converted image data is transmitted to the output destination set in the output condition, and the process is terminated. If an e-mail address is set according to the output conditions, set the e-mail address set according to the output conditions to the destination, generate an e-mail containing the second converted image data, and send the e-mail to the e-mail server. Send to.

In the present embodiment, as an example of the process of outputting the image data, the case of transmitting the image data to the outside has been described, but the image forming unit 140 may form the image of the image data on the paper. The external storage device 117 may be controlled to store image data in a recording medium such as a semiconductor memory.

As described above, the MFP 100 in the present embodiment functions as a document reading device, the scanning conditions are set, the scanning mode is set, and the document is subjected to either the set scanning conditions or the predetermined scanning conditions. Is switched depending on the condition of the document or the scanning conditions. Therefore, it is possible to shorten the scanning time of the original as much as possible and determine the scanning conditions under which the image data of high image quality, which is likely to be set by the output conditions, can be output. Therefore, it is possible to set reading conditions suitable for the usage mode by the user.

Further, when the second mode for reading the original under the predetermined maximum scanning condition is set and the number of originals is equal to or larger than the predetermined number, the first mode for scanning the original under the set scanning condition is set. Switch. When the number of originals is large, the amount of image data is large, so that the time for processing the image data can be shortened.

Further, when the first mode for scanning the original under the set scanning conditions is set and the scanning conditions for processing the image quality higher than the predetermined image quality are set, the original is scanned under the maximum scanning conditions. Switch to 2 modes. The image quality of the image data can be lowered, but not high. Therefore, when the scanning conditions of a predetermined image quality or higher are set, the image data of the image quality determined by the output conditions can be output by scanning the original under the maximum scanning conditions.

Further, when the second mode for scanning the original is set under the maximum scanning condition and the condition for processing the character image is set, the mode is switched to the first mode. In many cases, the character image can be identified even if the amount of data is reduced. Therefore, when the image data includes the character image, the processing speed can be prioritized and the waiting time of the user can be shortened.

The maximum scanning condition is determined by the ability to read the original, and is the condition in which the photograph is set as the setting value of the image type among the scanning conditions, and the condition in which the maximum resolution is set as the setting value for determining the resolution, and the color. It is a condition that the color is set to the set value of the number. Therefore, it is possible to acquire the image data having the highest image quality.

Further, when the user sets the reading mode, the reading mode set by the user is changed. Therefore, when the image quality required for the image data is changed at the time of output after the user has set the reading mode, the image quality required for the image data is changed. Image data can be output with the required image quality.

Further, since the reading mode set in the folder in which the image data is stored among the plurality of folders included in the HDD 115 is changed, the user does not need to set the reading mode, and the operation becomes easy.

Further, from the first converted image data and the second converted image data, the data having the same image quality as the image quality of the data to be output determined by the output condition is output according to the output condition, so that the image quality is determined by the output condition. Image data can be output.

In particular, when the image quality of the data to be output determined by the output conditions and the image quality of the first converted image data do not match, the image data is an output image having the same image quality as the image quality of the data to be output determined by the output conditions. Since it is converted into data, the image data can be output with the image quality determined by the output conditions.

Further, in response to the image data being stored in the HDD 115, the second converted image data obtained by converting the image data according to the conversion conditions set in the folder in which the image data is stored is generated, so that the output condition is input. It is possible to shorten the time from to output the first converted image data. Further, if the image quality of the data to be output determined by the output conditions and the image quality of the first image data match, the first converted image data is output, so the image data is output with the image quality determined by the output conditions. can do.

If the image quality of the data to be output determined by the output conditions and the image quality of the first converted image data do not match, the second image data has the same image quality as the image quality of the data to be output determined by the output conditions. Since the converted image data is converted and the second converted image data is output, the image data can be output with the image quality determined by the output conditions.

Further, if the conversion condition is not set in the folder in which the image data of the HDD 115 is stored at the stage when the output condition is acquired, the conversion condition is set in the folder based on the output condition, so that the conversion condition is set. The setting operation can be omitted, and the operation can be simplified.

The format and image quality specified by the output conditions are compared with the format and image quality of the image data, and if they match, the image data is determined as the output target, and the image data is output according to the output conditions. You may do so.
