The input unit 14 includes an input device for receiving various input operations. The input unit 14 of the present embodiment includes at least the touch panel 7 described above as an input device.

  The reading unit 15 includes an image sensor and is configured to be able to scan a document. The reading unit 15 executes scanning according to the setting values for each of a plurality of types of setting items necessary for scanning according to the control command from the control unit 11. The reading unit 15 is configured to be able to execute a single-sided scan that scans only one side image of the front and back sides of the document, and a double-sided scan that individually scans the double-sided image.

  That is, the reading unit 15 can perform single-sided scanning on the document placed on the document table 4. On the other hand, the reading unit 15 can selectively execute both single-sided scanning and double-sided scanning on a document placed on the ADF 5 and conveyed by the ADF 5. It should be noted that double-sided scanning may also be possible for a document placed on the document table 4.

The printing unit 16 has a printing mechanism using an inkjet technique or an electrophotographic technique, and can print an image on a sheet-like recording sheet.
The document table document sensor 17 is configured to detect that a document is placed on the document table 4. Various specific configurations of the platen original sensor 17 are conceivable. For example, a configuration in which the reading unit 15 detects the presence or absence of a document by scanning the entire document table 4, that is, a configuration in which the reading unit 15 functions as a part of the document table document sensor 17 may be employed.

  Specifically, when the cover 3 is opened and closed again by a cover opening / closing sensor (not shown), the reading unit 15 scans the entire document table 4, and as a result of scanning, the reading unit 15 faces the document table 4 in the cover 3. When only a reflected light level signal indicating the surface to be touched (for example, white) is detected, it is determined that no document is placed, and a signal having a level lower than the reflected light level indicating the surface facing the document table 4 is determined. May be determined that a document is placed.

  Note that, based on the result of scanning of the document table 4 by the reading unit 15, in addition to the presence or absence of a document, the document size may be detected when a document is placed.

It is configured to be able to detect information.

  The document size detector 19 also detects the size information of the document placed on the document table 4 even when the document table document sensor 17 detects that the document is placed on the document table 4. The document size detection unit 19 according to the present embodiment scans a specific area of the document table 4 by the reading unit 15 and detects the size information of the document placed on the document table 4 based on the scanning result. It is configured. Since the specific area scanned by the reading unit 15 is a part of the entire document table 4, the document size may be uniquely determined depending on the size and orientation of the document, or the document size may be determined. There are cases where size information including the possibility of a plurality of types of document sizes is detected without being uniquely determined. In the present embodiment, for example, an A4 size document is uniquely detected to be A4 size depending on the orientation in which it is placed. On the other hand, an A3 size document is configured so that it cannot be uniquely detected that it is A3 size. When an A3 size document is placed on the document table 4, the document size detection unit 19 detects size information indicating that the document size may be at least one of A3 and A4 based on the scanning result. To do.

The communication unit 20 is a communication interface for connecting the image processing apparatus 10 to the LAN 9. The LAN 9 is connected to the Internet 100.
Next, the information processing apparatus 30 includes a control unit 31, a storage unit 32, an input unit 33, a display unit 34, and a communication unit 35, which are connected to each other via a bus 36.

Note that data communication between the image processing apparatus 10 and the information processing apparatus 30 is performed by way of the LAN 9 as an example, and data communication may be performed through another communication medium or by another communication method.

(1-3) Description of Scan Function When the image processing apparatus 10 is turned on and started, a standby screen is displayed on the display 6. The user can select a function to be executed from the standby screen. When the scan function is selected on the standby screen, a scan menu screen is displayed on the display 6.

  The scan menu screen is a screen on which more detailed options of the first sub-function that the scan function has are arranged. The scan function is subdivided into a plurality of first sub functions according to the output destination of the scan data. Specifically, for example, it is subdivided into a plurality of first sub-functions such as scan-to-media, scan-to-PC, and scan-to-network. Of these, scan to PC is a function of transmitting scan data to an information processing apparatus such as a personal computer or a tablet terminal. An information processing apparatus capable of transmitting scan data by scan-to-PC includes the information processing apparatus 30 of the present embodiment. When scan to PC is selected on the scan menu screen, a processing method selection screen is displayed on the display 6.

  The processing method selection screen is a screen on which options regarding how the scan data is transmitted to the information processing apparatus as the transmission destination are arranged. Scan to PC is subdivided into a plurality of functions according to the transmission mode of scan data. Specifically, it is subdivided into a plurality of functions such as scan to file, scan to OCR, scan to image, scan to e-mail attachment, and scan to memory storage. When one of the subdivided functions is selected by the user, a scan preparation screen corresponding to the selected function is displayed on the display 6. When scan-to-memory storage is selected, a scan preparation screen 40 as illustrated in FIG. 3 is displayed.

  The scan preparation screen 40 has a selection column display area 41. On the scan preparation screen 40, a scan execution button 45 is displayed in an area different from the selection column display area 41. In the selection column display area 41, there are a case where at least one selection column is displayed and a case where no selection column is displayed at all depending on the place where the document to be read is placed, the document size, and the like. FIG. 3 shows an example in which two selection fields 42 and 43 are displayed in the selection field display area 41.

  The image reading system 1 of the present embodiment temporarily stores scan data scanned by the image processing apparatus 10 in the storage unit 12 of the image processing apparatus 10, and later stores the saved scan data from the information processing apparatus 30. The so-called pull scan to be acquired can be realized. The scan-to-memory storage is one of the functions for realizing the pull scan, and both the pull scan control process in FIG. 9 and the scan data transmission process in FIG. 11 are processes for realizing the scan-to-memory storage. It is.

  The information processing apparatus 30 is also installed with scan software that is software for realizing pull scan. This scan software includes a scan data acquisition processing program shown in FIG.

  In the image processing apparatus 10, as a plurality of types of setting items whose setting values are used when scanning a document, for example, a duplex scanning setting indicating which of a double-sided image or a single-sided image is to be read, a document size Settings, resolution settings, color settings, file format settings, brightness settings, contrast settings, etc.

  Among these multiple types of setting items, in the present embodiment, at least the duplex scanning setting and the document size setting are specific setting items for which setting values are estimated before the start of scanning when executing scan-to-memory saving.

  At the start of scan-to-memory storage, first, specific setting values are provisionally set for each of a plurality of types of setting items. The provisional setting means that the setting value of the corresponding setting item is provisionally set, and the setting can be changed later in both the image processing apparatus 10 and the information processing apparatus 30. Hereinafter, the temporarily set value is also referred to as a temporarily set value.

  After that, for the specific setting item, the corresponding setting related information is acquired before the start of scanning, and any one or a plurality of set values corresponding to the setting related information are estimated from the settable setting values. The setting related information is information that can be detected by the image processing apparatus 10 among information related to the setting value of the corresponding specific setting item. More specifically, the setting related information is an appropriate setting to be used for a scan to be executed in the future. This is information that can estimate the value, or information that can estimate a setting value that the user may desire to set in a scan to be executed in the future.

  In the present embodiment, for the duplex scanning setting, as setting related information, there is information indicating the detection state of the document table original sensor 17 and the ADF original sensor 18, that is, placement information. As for the document size setting, there is information indicating the detection state of the document size detection unit 19, that is, size information, as setting related information.

  For specific setting items for which a plurality of setting values are estimated, a selection column in which the plurality of setting values are arranged as candidate setting values is displayed in the selection column display area 41 of the scan preparation screen 40. However, when a plurality of setting values are estimated for a specific setting item, the estimated plurality of setting values are not necessarily displayed in the selection column. In the present embodiment, for each specific setting item, a candidate setting value that is a setting value equal to or less than a specific maximum display number among a plurality of estimated setting values is displayed in the selection column. The maximum display number may be determined as appropriate, and is 2 in the present embodiment, for example.

  The scan preparation screen 40 shown in FIG. 3 includes a double-sided scan setting selection field 42 that is a selection field in which candidate setting values for double-sided scanning settings are arranged, and a document size that is a selection field in which candidate setting values for document size settings are arranged. An example in which a setting selection field 43 is displayed is shown.

  When the estimated number of setting values is plural and equal to or less than the maximum display number, all estimated setting values are displayed as candidate setting values in the selection column. On the other hand, when the estimated number of setting values exceeds the maximum display number, only the maximum display number candidate setting values are displayed among the estimated setting values. In this case, which setting value is displayed and which setting value is not displayed may be determined by various methods. For example, the suitability of setting as a set value for a scan to be executed from now on may be determined based on the setting related information, and the set value of the maximum display number may be selected and displayed in descending order of suitability. Further, for example, based on the setting related information, it is possible to determine the possibility that the user desires the setting for the scan to be executed in the future, and select and display the setting value of the maximum display number in descending order of the possibility.

  For specific setting items in which a plurality of candidate setting values are estimated and displayed, the maximum value among the displayed candidate setting values is provisionally set. When any candidate setting value is selected by the user, the selected candidate setting value is permanently set as the setting value of the specific setting item. When executing the scan, the scan is performed in accordance with the set value. Note that this setting means that the setting value of the corresponding specific setting item is formally determined and the setting cannot be changed from the information processing apparatus 30 later.

  For a specific setting item having only one estimated setting value, the selection column is not displayed on the scan preparation screen 40, and that one setting value is set as a temporary setting value. When the scan is executed, the scan is performed according to the temporarily set value.

  Regarding the duplex scanning setting, there are three types of setting values that can be set, for example, “single side”, “double side; long side binding”, and “double side: short side binding”. That is, it is possible to set whether to scan both sides or one side of the document as a reading target, and it is also possible to set the binding direction in the duplex scanning.

  In the present embodiment, the detection state of the platen original sensor 17 and the ADF original sensor 18 is acquired as setting-related information for the setting value of the duplex scanning setting which is one of the specific setting items, and based on the detection state, It is estimated whether either “double-sided” or “single-sided” is possible or should be “single-sided”.

  When it is detected by the ADF document sensor 18 that a document is placed on the ADF 5, the user may perform either double-sided scanning or single-sided scanning. That is, the fact that the document is placed on the ADF 5 may cause the user to desire to set both “double-sided” and “single-sided” as the setting values for the double-sided scan setting. For this reason, when it is detected by the ADF document sensor 18 that a document is placed on the ADF 5, “double-sided” and “single-sided” are estimated as candidate setting values.

  In this case, as illustrated in FIG. 3, a double-sided scan setting selection field 42 is displayed on the scan preparation screen 40, and a simple setting button indicating two estimated candidate setting values is displayed therein. Specifically, a single-sided button 42a indicating “single-sided” among the candidate setting values and a double-sided button 42b indicating “double-sided” among the candidate setting values are displayed. The user can easily and efficiently set the setting value of the double-sided scan setting by selecting one of the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection field 42.

  For the document size setting, for example, A3, A4, B5, B4, A5, 2L size, L size, postcard, A6, and the like are settable setting values. When executing scan-to-memory storage, the setting value of the original size setting, which is one of the specific setting items, is set when the original is placed on the ADF 5 or when the original is placed on the original table 4. As the setting related information, the detection state of the document size detection unit 19 is acquired and is estimated based on the detection state.

  Depending on the detection state of the document size detection unit 19, that is, the size and orientation of the placed document, one document size may be uniquely identified, or the document size may not be uniquely identified. If the document size cannot be uniquely specified, a plurality of document sizes that are possible as document sizes of the placed document are estimated based on the detection state. In other words, these candidate setting values can be said to be setting values that the user is likely to desire to set as the setting values for the document size setting.

  When any of a plurality of setting values that can be set as the document size is estimated based on the detection state of the document size detection unit 19, the scan preparation screen 40 is illustrated in FIG. Then, a document size setting selection column 43 is displayed. In the document size setting selection field 43, simple setting buttons for each candidate setting value equal to or less than the maximum display number among the estimated setting values are displayed. In FIG. 3, at least A3 and A4 are estimated as setting values for the document size setting, and an A3 button 43a indicating A3 and an A4 button 43b indicating A4 are displayed in the document size setting selection field 43 as simple setting buttons. An example is shown. The user can easily and efficiently set the setting value of the document size setting by selecting one of the simple setting buttons 43 a and 43 b displayed in the document size setting selection field 43.

  When only one document size is uniquely specified based on the detection state of the document size detection unit 19, that one document size is provisionally set as a setting value for document size setting. In this case, as illustrated in FIG. 6, the document size setting selection field 43 is not displayed on the scan preparation screen 40. The selection column is not displayed on the scan preparation screen 40 for a specific setting item having one estimated candidate setting value, not limited to the document size setting.

(1-4) Execution Example of Pull Scan Next, a specific aspect of the pull scan executed by the image reading system 1 of the present embodiment will be described with reference to FIGS. When scan-to-memory storage is selected and started, for example, it is detected that a document is placed on the ADF 5, so that both sides and one side are estimated as a duplex scan setting, and the document size detection unit 19 When two types of document sizes A3 and A4 are estimated based on the detection state, a scan preparation screen 40 shown in FIG. 3 is displayed. The contents of the scan preparation screen 40 in FIG. 3 are as described above.

  Immediately after the scan preparation screen 40 is displayed, the setting values of the plurality of types of setting items are initially set as the provisional setting values of the plurality of setting values that can be set. Note that the initial temporary setting value in the duplex scanning setting is binding on both sides and long sides, and the initial temporary setting value in the document size setting is A3.

  However, when the setting value is estimated for the specific setting item and a plurality of candidate setting values are displayed on the scan preparation screen 40, the temporary setting value is set to the maximum value among the plurality of candidate setting values for the specific setting item. Be changed.

  When both the duplex scanning setting and the document size setting are set with temporary setting values, the setting fields 42 and 43 indicate that the temporary setting values are set as “set later from PC”. A message is displayed.

  In this state, when the scan execution button 45 is selected, the document is scanned. During the scan execution, a running screen 50 indicating that the scan is being executed is displayed. On the in-execution screen 50, specific setting information 51 indicating information on setting values of specific setting items is displayed. In this case, scanning of the document is performed according to the temporary setting values for all the setting items. For this reason, as the specific setting information 51, a message “set later from PC” is displayed, which is information indicating that scanning is executed with the temporary setting value for each specific setting item. After the scan is completed, the scan data is stored in the storage unit 12.

  When, for example, the double-sided button 42b is selected from the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection field 42, double-sided is set as a setting value for the double-sided scan setting. In this case, as shown in FIG. 3, the double-sided button 42b is highlighted in the double-sided scan setting selection field 42, and a message “both sides” indicating that both sides are fully set is displayed. At this time, the main setting is to scan both sides of the document, and the main setting is not performed up to the binding direction. For the binding direction, a predetermined specific binding direction is provisionally set. In the present embodiment, the temporary setting value in the binding direction is “long edge”. For this reason, the double-sided scan setting selection field 42 displays a message “(Binding direction set later from PC)” indicating that a temporary setting value has been set for the binding direction.

  Further, when, for example, the A4 button 43b is selected among the simple setting buttons 43a and 43b displayed in the document size setting selection field 43, A4 is set as a setting value for the document size setting. In this case, as shown in FIG. 3, in the document size setting selection field 43, the A4 button 43b is highlighted, and a message “A4” indicating that A4 is fully set is displayed.

  When the scan execution button 45 is selected in a state where the duplex setting is set as the duplex scan setting and the A4 is set as the document size setting, the duplex scan setting and the document size setting are selected from among a plurality of types of setting items. Then, scanning is executed according to the set value set in the main setting. For this reason, as the specific setting information 51 displayed on the execution screen 50, regarding the duplex scanning setting, the duplex setting is performed because the duplex setting is actually set, and the temporary setting value is set for the binding direction. Information indicating that the setting can be changed later from the information processing apparatus 30 is displayed. As for the document size setting, information indicating that A4 is set and scanning is being executed is displayed.

  When, for example, the single-sided button 42a is selected from the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection column 42, one side is set as a setting value for the double-sided scan setting. In this case, as shown in FIG. 4, in the double-sided scan setting selection field 42, the single-sided button 42 a is highlighted and a message “single-sided” indicating that the single-sided main setting has been performed is displayed.

  Further, when, for example, the A3 button 43a is selected from the simple setting buttons 43a and 43b displayed in the document size setting selection field 43, A3 is set as the set value of the document size setting. In this case, as shown in FIG. 4, in the document size setting selection field 43, the A3 button 43a is highlighted, and a message “A3” indicating that A3 is fully set is displayed.

  When the scan execution button 45 is selected in a state where one side is set as the duplex scanning setting and A3 is set as the document size setting, the duplex scanning setting and the document size setting are selected from among a plurality of types of setting items. Then, scanning is executed according to the set value set in the main setting. Therefore, the specific setting information 51 displayed on the in-execution screen 50 has the contents shown in FIG. That is, as the specific setting information 51, for the double-sided scan setting, information indicating that the single-sided scan is being executed is displayed because one side is set as the main setting, and for the document size setting, A3 is set as the main setting. Information indicating that the scan is being executed is displayed.

  If it is desired to execute scanning using a setting value not displayed in the selection field, an area other than each simple setting button in the selection field may be selected. For example, when an area other than the simple setting buttons 42a and 42b in the duplex scan setting selection field 42 is selected, a duplex scan setting screen 60 shown in FIG. 5 is displayed.

  On the double-sided scan setting screen 60, setting value buttons 62 for all setting values that can be selected in the double-sided scan setting, and temporary setting buttons 61 for setting initial temporary setting values are displayed in an array. Then, by selecting any button, a setting value corresponding to that button is set. For example, when the setting value button 62 indicating the setting value of “double-sided scanning; long-side binding original” is selected, both the double-sided scanning and the long-side binding are actually set, and the screen returns to the scan preparation screen 40. When the setting value is set in the double-sided scan setting screen 60, the simple setting button is deleted from the double-sided scan setting selection field 42 as shown in FIG. A message indicating that both edge binding has been set is displayed.

  Further, for example, when an area other than the simple setting buttons 43a and 43b in the document size setting selection field 43 is selected on the scan preparation screen 40 shown in FIG. 4, the document size setting screen 65 shown in FIG. 5 is displayed. .

  On the original size setting screen 65, a setting value button 67 for every setting value that can be selected in the original size setting and a temporary setting button 66 for setting an initial temporary setting value are arranged and displayed. Then, by selecting any button, a setting value corresponding to that button is set. For example, when the set value button 67 indicating the set value of “B5” is selected, B5 is set as the set value of the document size setting and the screen returns to the scan preparation screen 40. When the set value is set on the original size setting screen 65, as shown in FIG. 5, the simple setting button is deleted from the original size setting selection field 43, and B5 is set in the original size setting selection field 43. A message is displayed indicating that this has been done.

  Then, both sides scanning and long-edge binding are set as main settings via the double-sided scan setting screen 60 as double-sided scan settings, and B5 is set as main settings via the document size setting screen 65 as document size settings. When the scan execution button 45 is selected, a scan is executed. In this case, as shown in FIG. 5, the in-execution screen 50 displays information indicating the setting values that are currently set for both the duplex scanning setting and the document size setting as the specific setting information 51.

  Next, another aspect of the pull scan will be described with reference to FIG. When scan-to-memory storage is started, for example, it is detected by the ADF document sensor 18 that a document is placed on the ADF 5, and the document size is A4 based on the detection state of the document size detection unit 19. Is uniquely identified, a scan preparation screen 40 shown in FIG. 6 is displayed.

  In the scan preparation screen 40 of FIG. 6, the display content of the double-sided scan setting selection field 42 is the same as that of FIG. Further, the setting value of the duplex scanning setting is the initial temporary setting value, which is the same as in FIG. Accordingly, when, for example, the single-sided button 42a is selected from the simple setting buttons 42a and 42b, the single-sided main setting is set as the setting value of the double-sided scan setting as shown in FIG.

  On the other hand, regarding the document size setting, since the document size is uniquely specified as A4, A4 is temporarily set as a setting value for the document size setting. However, in this case, the document size setting selection field 43 is not displayed.

  Then, as shown in FIG. 6, when A4 is uniquely specified as the setting value for the document size setting, A4 is provisionally set, and the setting value for the duplex scanning setting is set to one side by the user's selection operation. Thus, when the scan execution button 45 is selected, the scan is executed. As shown in FIG. 6, the in-execution screen 50 displays, as the specific setting information 51, that one side is set for the double-sided scan setting, and the original size setting is scanned with the temporary setting value. Is displayed.

  Still another aspect of the pull scan will be described with reference to FIG. When the scan-to-memory storage is started, for example, the original is not detected by the ADF original sensor 18 but is detected by the original plate original sensor 17, and the original is detected based on the detection state of the original size detecting unit 19. When A3 and A4 are estimated as sizes, a scan preparation screen 40 shown in FIG. 7 is displayed.

  In the scan preparation screen 40 of FIG. 7, the display content of the document size setting selection field 43 is the same as that of FIG. Also, the setting value of the document size setting is the initial temporary setting value, which is the same as in FIG. Accordingly, when, for example, the A4 button 43b is selected from the simple setting buttons 43a and 43b, A4 is set as a setting value for the document size setting as shown in FIG.

  On the other hand, regarding the duplex scanning setting, since it is detected that the document is placed on the document table 4, one side is set as the setting value of the duplex scanning setting. However, in this case, the double-sided scan setting selection field 42 is not displayed.

  Here, in this embodiment, when only one setting value is uniquely specified based on the setting related information, as a rule, that one setting value is provisionally set. However, as an exception, when the setting value of the double-sided scan setting is uniquely specified on one side due to the original being placed on the platen 4, when setting the setting value of the double-sided scanning setting on one side, It is configured to use this setting instead.

  As shown in FIG. 7, when the scan execution button 45 is selected in a state in which one side is set as a setting value for duplex scanning setting and the setting value for document size setting is set to A4 by the user's selection operation. A scan is performed. Then, on the execution screen 50, as shown in FIG. 7, as the specific setting information 51, it is displayed that one side is set for the duplex scanning setting, and A4 is set for the document size setting. Is displayed.

  When scan-to-memory storage is executed in the image processing apparatus 10, the document is scanned, and scan data is generated and stored in the storage unit 12. The user can acquire the stored scan data from the information processing apparatus 30.

  In the information processing apparatus 30, when the user activates the scan software and performs a predetermined operation for executing the pull scan, the scan setting screen 80 illustrated in FIG. 8 is displayed on the display unit 34 of the information processing apparatus 30. . The scan setting screen 80 is a screen on which setting values of a plurality of types of setting items used for scanning can be set.

  When the scan setting screen 80 is displayed for the first time after the scan software is started, the setting values of the setting items in the scan setting screen 80 are used when scan data stored in the storage unit 12 of the image processing apparatus 10 is scanned. The selected set value is displayed in a selected state. Further, the setting value used as the setting value at the time of scanning is displayed so that the setting cannot be changed.

  In FIG. 8, the document size selection box 81 for selecting the setting value of the document size setting is in a state where A4 is set as the document size and cannot be changed to another size. This is because A4 is used as the setting value for the document size setting when the scan data stored in the storage unit 12 of the image processing apparatus 10 is scanned. On the other hand, as for the setting values of the double-sided scan setting, since both the double-sided and the long side binding are used as the temporary setting values at the time of scanning by the image processing apparatus 10, the temporary setting values used are selected. It is displayed. Since it is a temporary setting value, the setting value of the duplex scan setting can be changed. For example, by switching check marks in the binding direction check field 83, the binding direction can be changed to a short side binding. Also, for example, by removing the check from the duplex setting check box 82, it is possible to change to single-sided scanning.

  When the scan button 86 displayed on the scan setting screen 80 is selected, a scan data request including user setting information indicating the setting value of each setting item set at that time is transmitted to the image processing apparatus 10. . As a result, in the image processing apparatus 10, the stored scan data is converted according to the transmitted user setting information, and the converted scan data is transmitted from the image processing apparatus 10.

  Note that the conversion referred to here specifically corresponds to the setting value indicated by the user setting information when the setting value used at the time of scanning is different from the setting value indicated by the user setting information. It means that the content is converted. In other words, scan data that has already been stored is converted so that the scan data is the same as or equivalent to the scan data that would have been generated if the scan was executed with the setting value indicated by the user setting information.

  For example, when the setting value of the document size setting is A3 at the time of the scan execution, the information processing apparatus 30 subsequently changes the setting value to A4, and the fact that the change to A4 is transmitted to the image processing apparatus 10 as user setting information. The image processing apparatus 10 converts the stored scan data into A4 size scan data. For example, when the setting value of the double-sided scan setting is double-sided at the time of executing the scan, and the information processing device 30 subsequently changed to the single side and changed to the single side, the user setting information is transmitted to the image processing device 10 The image processing apparatus 10 converts the stored scan data into scan data composed of image data for one side by removing image data for one side of each original. In this way, once the scan data once generated is instructed to be changed to a different setting value from the information processing apparatus 30, it can be converted into scan data corresponding to the instructed setting value.

(1-5) Description of Each Process for Realizing Pull Scan Next, processes executed by the image processing apparatus 10 and the information processing apparatus 30 to realize the above-described pull scan will be described with reference to FIGS. I will explain.

  First, the pull scan control process executed by the image processing apparatus 10 will be described with reference to FIG. When the scan-to-memory storage is selected on the above-described processing method selection screen, the control unit 11 of the image processing apparatus 10 executes a pull scan control process shown in FIG.

  When starting the pull scan control process of FIG. 9, the control unit 11 of the image processing apparatus 10 displays the scan preparation screen 40 on the display 6 in S <b> 110. In S120, a specific setting value is provisionally set as an initial value for each of a plurality of types of setting items. Specifically, for the document size setting which is one of the specific setting items, A3 which is the maximum value among the settable setting values is temporarily set. For double-sided scan setting, which is one of the specific setting items, double-sided and long-edge binding, which are maximum values among settable setting values, are temporarily set. As for the setting values of the other setting items, the maximum value among the setting values that can be set is temporarily set. Note that the maximum value here means a setting value that maximizes the amount of scan data. Therefore, for example, for the setting value of the resolution setting, the maximum value among the settable resolutions is provisionally set.

  In S <b> 130, it is determined whether or not a document is placed on the ADF 5 or the document table 4 based on the detection results of the document table document sensor 17 and the ADF document sensor 18. If no document is placed on either the ADF 5 or the document table 4, the process proceeds to S150. If a document is placed on the ADF 5 or the document table 4, the process proceeds to S140.

  In S140, a setting item display process is executed. Details of the setting item display processing in S140 are as shown in FIG. As shown in FIG. 10, when the process proceeds to the setting item display process, in S310, it is determined whether or not the document is placed on the ADF 5. If the document is not placed on the ADF 5, that is, if it is placed on the document table 4, the process proceeds to S330. At this time, although not shown, one side is set as the setting value of the double-sided scan setting.

  If the document is placed on the ADF 5, the double-sided scan setting selection field 42 is displayed in the selection field display area 41 of the scan preparation screen 40 in S320. At this time, the display content of the double-sided scan setting selection field 42 depends on the setting state of the setting value of the double-sided scan setting. That is, when the setting value is temporarily set, the simple setting buttons 42a and 42b are displayed and the temporary setting value is set as in the double-sided scan setting selection field 42 illustrated in the upper left of FIG. A message is displayed indicating that On the other hand, when one of the double-sided and single-sided is set by user selection, as illustrated in the lower left of FIG. 3 and the lower left of FIG. 6, a simple setting button corresponding to the set value that is set Is highlighted, and a message indicating the set value is displayed.

  In S330, it is determined whether or not the document size setting value is a temporary setting value. If the setting value is set instead of the temporary setting value, the setting item display process is terminated, and the process proceeds to S150. If it is a temporarily set value, the process proceeds to S340. In S340, a detection result by the document size detection unit 19, that is, size information is acquired.

  In S350, based on the detection result acquired in S340, it is determined whether or not the size of the placed document can be uniquely specified as one set value. If the document size can be uniquely specified, the process proceeds to S360. In S360, the document size setting setting value is provisionally set to a uniquely specified setting value. After the process of S360, the process proceeds to S150.

  In S350, if one original size cannot be uniquely specified, the process proceeds to S370. In S370, the document size setting selection field 43 is displayed in the selection field display area 41 of the scan preparation screen 40. At this time, in the document size setting selection field 43, a simple selection button of a setting value equal to or less than the maximum display number among the document sizes estimated based on the detection result is displayed. In S380, the maximum size among the document sizes displayed in S370 is provisionally set as a setting value for the document size setting. After the process of S380, the process proceeds to S150.

  Returning to FIG. 9, in S150, it is determined whether or not an operation on the touch panel 7 by the user has been performed. When the operation on the touch panel 7 is not performed, the process returns to S130, and when the operation on the touch panel 7 is performed, the process proceeds to S160. In S160, it is determined whether or not the operation on the touch panel 7 performed by the user is an operation for setting the document size, that is, an operation on the document size setting selection field 43 in the scan preparation screen 40. If it is not an operation for setting the document size, the process proceeds to S180. If it is an operation for setting the document size, the process proceeds to S170.

  In S170, the setting value of the document size setting is set to the setting value selected via the touch panel 7 by the user. Further, the display content of the document size setting selection field 43 is also switched according to this setting. At this time, if the setting value is set by the user via the document size setting screen 65 shown in FIG. 5, the simple setting button is not displayed in the document size setting selection field 43 as described with reference to FIG. Display. After the process of S170, the process returns to S130.

  In S180, whether or not the operation on the touch panel 7 performed by the user is an operation for setting a setting value of the duplex scan setting, that is, an operation on the duplex scan setting selection field 42 in the scan preparation screen 40. to decide. If it is not an operation for setting the setting value of the duplex scanning setting, the process proceeds to S200. If it is an operation for setting the setting value of the duplex scan setting, the process proceeds to S190.

  In S190, the setting value for the duplex scanning setting is set to the setting value selected by the user via the touch panel 7. At this time, if any of the simple setting buttons is selected, the setting value corresponding to the selected simple setting button is set for the double-sided or single-sided setting. However, in this case, the temporary setting state of the long side binding is maintained for the binding direction. On the other hand, when the setting value is set by the user via the double-sided scan setting screen 60 shown in FIG. 5, as described with reference to FIG. 5, either double-sided or single-sided setting or binding direction setting is selected. This setting is also used, and the simple setting button is not displayed in the double-sided scan setting selection field 42. After the process of S190, the process returns to S130.

  In S200, it is determined whether or not the scan execution button 45 in the scan preparation screen 40 has been selected. If the scan execution button 45 is not selected, the process returns to S130. If the scan execution button 45 is selected, the process proceeds to S210.

  In S210, the document is scanned. In other words, the document is scanned according to the currently set values. After the scan is completed, the scan data generated by the scan of S210 is stored in the storage unit 12 in S220.

  Next, scan data transmission processing executed by the image processing apparatus 10 will be described with reference to FIG. When the scan data is stored in the storage unit 12 as a result of the execution of the pull scan control process of FIG. 9, the control unit 11 of the image processing apparatus 10 uses the stored scan data as a processing target, as shown in FIG. Execute scan data transmission processing.

  When the control unit 11 of the image processing apparatus 10 starts the scan data transmission process of FIG. 10, the scan information request transmitted from the information processing apparatus 30 is received via the communication unit 20 in S510. In S520, scan information indicating the setting value of each setting item used when executing scan of the stored scan data is transmitted to the information processing apparatus 30 via the communication unit 20. The scan information includes information indicating whether the setting value is a temporary setting value or a main setting value for each setting value. That is, the temporary setting value is associated with temporary setting information indicating that it is a temporary setting value. The setting value is associated with the setting information indicating the setting value.

  In S530, scan data including user setting information transmitted from the information processing apparatus 30 is received via the communication unit 20. In S540, the scan data stored in the storage unit 12 is converted based on the received user setting information. However, conversion is not performed when each setting value used at the time of executing the scan and each setting value indicated by the user setting information are exactly the same. In S550, the scan data after the conversion in S540 is transmitted to the information processing apparatus 30 via the communication unit 20. If the conversion is not performed in S540, the scan data stored in the storage unit 12 is transmitted to the information processing apparatus 30 without conversion.

  Next, scan data acquisition processing executed by the information processing apparatus 30 will be described with reference to FIG. When the scan software is activated and a predetermined operation for performing a pull scan is performed, the control unit 31 of the information processing apparatus 30 executes a scan data acquisition process illustrated in FIG.

  When starting the scan data acquisition process of FIG. 12, the control unit 31 of the information processing apparatus 30 displays the scan setting screen 80 shown in FIG. 8 on the display unit 34 in S610. In S620, a scan information request is transmitted to the image processing apparatus 10 via the communication unit 35. In S630, the scan information transmitted from the image processing apparatus 10 is received via the communication unit 35.

  In S640, scan information reflection processing is executed. This scan information reflection process is a process for matching the setting state of each setting item on the scan setting screen 80 with the setting value of each setting item indicated by the received scan information. Specifically, the setting value of each setting item on the scan setting screen 80 is the setting value indicated by the received scan information, that is, the setting used at the time of scan execution of scan data stored in the storage unit 12 of the image processing apparatus 10. Make the value selected. Further, the setting value used as the setting value at the time of scanning is displayed in a state where the setting cannot be changed.

  In S650, a user setting change operation on the scan setting screen 80 is accepted. When the scan button 86 is selected by the user, a scan data request including user setting information is transmitted to the image processing apparatus 10 via the communication unit 35 in S660. In S670, the scan data transmitted from the image processing apparatus 10, that is, the scan data converted based on the user setting information transmitted in S660 is received via the communication unit 35.

(1-6) Effect of Embodiment According to the embodiment described above, the following effects (1a) to (1e) are obtained.
(1a) In the image processing apparatus 10, for a specific setting item among a plurality of types of setting items, when there are a plurality of candidate setting values corresponding to the setting related information, the plurality of candidate setting values are displayed. The user can select any one of a plurality of displayed candidate setting values, and by selecting any one of the candidate setting values, the user can read an image according to the selected candidate setting value. Can do. That is, for a specific setting item, when there are a plurality of candidate setting values corresponding to the setting related information, the user can select any one of the plurality of candidate setting values. The setting value of the item can be set easily and appropriately.

Therefore, it is possible to suppress the data amount of the read image data while improving user convenience and convenience when executing image reading.
(1b) When the set value is estimated to be larger than the maximum display number, a set value equal to or less than the maximum display number among the estimated set values is displayed on the scan preparation screen 40 as a candidate set value. In addition, in the present embodiment, which of the plurality of estimated setting values is displayed as the candidate setting value is selected based on the setting related information. For example, the maximum display number setting is set in descending order of the suitability of setting as a set value for a scan to be executed in the future, or in the order in which the user is likely to desire setting for a scan to be executed in the future. A value is selected as a candidate set value. Therefore, the user can easily and efficiently select candidate setting values.

  (1c) As a result of estimation, when only one set value is uniquely specified, the set value is provisionally set and used for scanning. Therefore, the user does not need to set the setting value for the specific setting item for which the setting value is uniquely specified. In addition, for the specific setting item, an appropriate setting value is set and scanning is performed without requiring a user's setting operation.

  (1d) After executing the scan, in response to a request from the information processing device 30, scan information indicating the setting value of each setting item used for the scan is transmitted to the information processing device 30. Therefore, in the information processing apparatus 30, the user can confirm what setting value is scanned in the image processing apparatus 10 by looking at the scan setting screen 80 illustrated in FIG. 8.

  Further, the user can instruct a setting value different from the setting value used at the time of scanning via the scan setting screen 80. The content of the setting value change instruction by the user is transmitted to the image processing apparatus 10 as user setting information. When the image processing apparatus 10 receives the user setting information, the image processing apparatus 10 converts the scan data according to the setting value indicated by the user setting information, and transmits the converted scan data to the information processing apparatus 30. Therefore, the user can easily acquire the scan data at the setting value desired by the information processing apparatus 30.

  (1e) Further, in the scan information transmitted from the image processing apparatus 10 to the information processing apparatus 30, information indicating whether the setting value is a temporary setting value or a main setting value is associated with each setting value. It is done. In the information processing apparatus 30, the setting item for which this setting value is set cannot be changed, and the setting item for which the temporary setting value is set can be changed. Therefore, the user can efficiently change the setting for a setting value whose setting can be changed.

As mentioned above, although embodiment of this invention was described, this invention can be implemented in various deformation | transformation, without being limited to the above-mentioned embodiment.

  (2-1) In the above-described embodiment, the specific setting items are the double-sided scan setting and the document size setting. However, which of the plurality of types of setting items is set as the specific setting item may be appropriately determined.

  For example, the resolution at the time of scanning may be set as the specific setting item. In this case, as setting-related information, for example, a free space capable of storing scan data in the storage unit 12 is detected, and a resolution according to the free space among a plurality of setting values selectable as resolutions according to the free space At least one candidate set value may be estimated.

  More specifically, for example, it is assumed that there are four types of setting values that can be set as the resolution: 100 dpi, 200 dpi, 300 dpi, and 600 dpi. As a result of detecting the free space in the storage unit 12, if the scan is executed with the resolution set to 600 dpi, the scan data capacity may exceed the free space. If the resolution is set to 300 dpi or less, the scan data capacity is set. Is less than the free space. In this case, 300 dpi or less is estimated as the candidate resolution setting value. Then, of the estimated candidate setting values of 300 dpi or less, candidate setting values equal to or less than the maximum display number are selected and displayed in the selection column corresponding to the resolution in the scan preparation screen. When the maximum display number is 2, for example, 300 dpi and 200 dpi are displayed as candidate setting values, and either one is selected.
