JP 2004-88344 A

  When an image read by the image reading device is displayed on the display screen of the information processing terminal, in general, the image is often displayed with a display size corresponding to the reading resolution. For this reason, if the image is not read at an appropriate reading resolution, the visibility of the image displayed on the display screen may be reduced, making it difficult to confirm the image.

  For example, when an image is read at a low reading resolution and the image is displayed in a small size on the display screen, it is difficult to confirm the image. On the contrary, as a result of reading an image with a high resolution, it is difficult to confirm the image even when the image is displayed in a large size on the display screen and a part of the image protrudes from the screen.

  The present invention has been made in view of the above problems, and enables an information processing terminal to instruct an image reading apparatus to read an image at an appropriate reading resolution in accordance with the information processing terminal, its user, or the like. With the goal.

  The reading control program of the present invention made to solve the above problems is a program that is executed by a control unit in an information processing terminal including a display unit, a communication unit, and a control unit. The display unit can display an image, the communication unit can transmit and receive data to and from the image reading apparatus, and the control unit executes processing according to a program.

  When the image reading apparatus receives an image reading instruction and a reading resolution setting value from the information processing terminal, the image reading apparatus reads an image of the document at the received reading resolution and transmits image data indicating the read image to the information processing terminal. It is configured to

The reading control program is a program for causing the control unit to execute a transmission process, an image data acquisition process, an initial display process, a display size change process, and an optimum resolution determination process.

  The transmission process is a process for transmitting the setting value of the reading resolution corresponding to the optimum resolution, which is the optimum resolution when the image is read by the image reading apparatus, and the reading instruction to the image reading apparatus via the communication unit. is there. The image data acquisition process is a process of acquiring image data from the image reading apparatus received by the communication unit for the transmission process after the transmission process is executed. The initial display process is a process in which the image indicated by the image data acquired by the image data acquisition process is displayed on the display unit at an initial display size that is a specific display size according to the reading resolution at the time of reading the image in the image reading apparatus. It is. The display size changing process is a process of changing the display size of an image according to the display size changing operation when the display size changing operation is performed on the image displayed on the display unit by the initial display process. The optimum resolution determination process is a process for determining the optimum resolution by a specific calculation based on the difference between the display size after the change by the display size changing process and the initial display size.

  According to the reading control program of the present invention, when the display size is changed from the initial display size while the image read by the image reading device is displayed on the display unit of the information processing terminal, the change is performed. The optimum resolution is determined based on the degree (difference from the initial display size). As a result, when a reading instruction is subsequently transmitted to the image reading apparatus, a setting value of the reading resolution corresponding to the determined optimum resolution is transmitted. Therefore, it is possible to instruct the image reading apparatus from the information processing terminal to read the image with an appropriate reading resolution in accordance with the information processing terminal and its user.

  In the reading control program of the present invention, in the optimum resolution determination process, when the display size after the change is enlarged with respect to the initial display size, a specific resolution larger than the reading resolution at the time of reading with the image reading device is newly added. You may make it the optimal resolution.

  When the display size is enlarged from the initial display size, the image is small and difficult to see at the initial display size, and it is appropriate to display the image at a larger size (that is, to read at a higher reading resolution). . Therefore, when the display size is enlarged from the initial display size, the optimum resolution can be set to a large value, and thereafter, image reading can be instructed at an appropriate reading resolution based on the fact that the display size has been enlarged. it can.

  On the contrary, when the display size after the change is reduced with respect to the initial display size, in the optimum resolution determination process, a specific resolution smaller than the reading resolution at the time of reading with the image reading device is set as the new optimum resolution. You may make it do.

  When the display size is reduced from the initial display size, the image is large and difficult to see at the initial display size, and it is considered appropriate to display the image at a smaller size (that is, to read at a lower reading resolution). . Therefore, when the display size is reduced from the initial display size, the optimum resolution can be set to a small value, and thereafter, image reading can be instructed at an appropriate reading resolution based on the fact that the display size has been reduced. it can.

  More specifically, the determination of the optimal resolution in the optimal resolution determination process may be performed with reference to a table. That is, the table includes size change information indicating a difference between the initial display size and the changed display size, and resolution change information indicating how much the optimum resolution should be changed from the reading resolution at the time of reading by the image reading device. Is a table associated with. In the optimum resolution determination process, a new optimum resolution is determined based on the resolution change information associated with the difference in the table.

  As described above, by determining the optimal resolution using the table in which the size change information and the resolution change information are associated with each other, it is possible to easily determine an appropriate optimal resolution according to the display size change operation. it can.

  The reading control program of the present invention may further execute a storage process, a folder determination process, and a folder selection acceptance process. The storage process is a process of storing the image data acquired by the image data acquisition process in a specific folder among at least one folder. The folder-specific determination process is performed for each folder based on the optimal resolution determined when the optimal resolution determination process is performed for each image data stored in the folder, and the folder having the optimal resolution corresponding to the folder. This is a process for determining another optimum resolution. The folder selection accepting process is a process for accepting an operation for selecting a folder for storing image data. In the transmission process, the reading resolution setting value corresponding to the optimum resolution for each folder corresponding to the folder received by the folder selection receiving process may be transmitted.

  By associating the optimum resolution (optimum resolution for each folder) corresponding to the folder for each folder in which the image data is stored, the optimum resolution can be set for each folder (suitable for the folder). Therefore, when the user performs image reading, an image can be read at an appropriate reading resolution (optimal resolution for each folder) corresponding to the selected folder by appropriately selecting a folder for storing image data. .

  In the folder-specific decision process, the average calculation of the optimum resolution determined when the optimum resolution decision process is performed for each image data stored in the folder to be decided is performed, and the result of the average calculation is calculated for each folder. The optimum resolution may be determined.

  For each folder, the optimal resolution for each folder can be easily determined by determining the optimal resolution for each folder by averaging the optimal resolution corresponding to each image data stored in the folder. be able to.

  When the image reading apparatus is configured to be able to read an image at any one of a plurality of preset reading resolutions, the transmission process reads the closest one of the plurality of reading resolutions to the optimum resolution for each folder. The resolution setting value may be transmitted.

  By instructing (sending) the setting value of the reading resolution closest to the optimum resolution for each folder among a plurality of types of reading resolutions that can be set by the image reading apparatus, an instruction of the optimum reading resolution for the image reading apparatus Can be performed appropriately and easily.

(4) Overview of Scan Function The scan function realized by the CPU 21 of the mobile device 3 executing the scan application 42 will be described in detail.

(4-1) Pull Scan In the mobile device 3, when the scan application 42 is activated by a user operation (that is, executed by the CPU 21), the menu screen shown in FIG. The When the user taps the end button on this menu screen, the scan application 42 ends.

When the user taps the scan data browsing button on the menu screen, stored scan data (scan data of an image scanned in the past by the multi-function device 5) is displayed. Specifically, first, a list of folders storing scan data is displayed. When the user taps a desired folder, a list of scan data in the folder is displayed. There are various methods for displaying scan data. For example, file names of scan image data may be displayed as a list, thumbnails (reduced images) of scan data may be displayed as a list, or an image of one scan data may be displayed. You may display by a specific display size (initial display size).

  When a file name or thumbnail is displayed, when the user taps desired scan data, an image (scan image) of the scan data is displayed in a specific initial display size. Note that the initial display size is individually set for each scan image to be displayed. In other words, in the present embodiment, the setting is set according to the reading resolution when the scan image to be displayed is scanned by the multifunction device 5. The lower the reading resolution during scanning, the smaller the initial display size. Conversely, the higher the reading resolution during scanning, the larger the initial display size.

  When the scan image is displayed on the display unit 16 at the initial display size, the user performs a predetermined enlargement operation or reduction operation while the scan image is displayed, thereby changing the display size of the scan image from the initial display size. It can be changed (enlarged or reduced). Various specific methods of the enlargement operation and the reduction operation can be considered. For example, a pinch-out operation with respect to the touch panel 14 can be considered as the enlargement operation, and a pinch-in operation with respect to the touch panel 14 can be considered as the reduction operation.

  When the user taps the scan execution button on the menu screen, the scan execution screen shown in FIG. This scan execution screen is a screen for accepting settings such as various setting values necessary for the scan execution and instructing the multifunction device 5 to execute the scan.

  As shown in FIG. 2B, on the scan execution screen, the reading resolution, the scan data file format, the original size of the scan target, and the scan data storage folder when scanning with the multi-function device 5 are respectively The set value is displayed. A scan start button and a return button are also displayed. When the return button is tapped, the menu screen of FIG.

  When the user taps the “read resolution” display area on the scan execution screen, a read resolution setting screen as shown in FIG. 2C is displayed. This reading resolution setting screen displays a list of reading resolutions that the multi-function device 5 can handle when executing scanning. When the user selects (tap) a desired resolution from the displayed resolutions, the selected resolution is set as the reading resolution, and the screen returns to the scan execution screen in FIG. In the scan execution screen, the selected resolution is displayed in the reading resolution display area.

  In the reading resolution setting screen of FIG. 2C, “automatic setting” is displayed as a selection menu in addition to the numerical value of the resolution. When the user selects this automatic setting as the reading resolution, an optimum resolution is automatically set as the reading resolution as described later.

  On the scan execution screen, the user can select setting items other than the reading resolution in the same manner as the reading resolution. As for the folder in which the scanned image data is stored in the mobile device 3, the user taps the display area of “save destination folder” to display a folder selection screen (not shown), thereby selecting a desired storage destination folder. You can choose.

When the user taps a scan start button on the scan execution screen, a scan instruction and scan setting information (respective setting values such as resolution, file format, and document size) are wirelessly transmitted to the multi-function device 5 (in this embodiment, a wireless LAN). Is done.

  With reference to FIG. 3A, an example of a sequence at the time of pull scanning when the automatic automatic setting is selected as the reading resolution will be described. As shown in FIG. 3A, an application (scan application 42) is activated in the mobile device 3, automatic setting is selected as the reading resolution, and a scan start button (see FIG. 2B) is selected (tap). ), A scan instruction and scan setting information are transmitted from the mobile device 3 to the multi-function device 5. Among the various setting information included in the scan setting information, for the setting value of the reading resolution, since the automatic setting is selected as the reading resolution in this example, the optimum resolution setting value determined at the time of selection is Sent.

  As a result, the multifunction device 5 performs scanning at the optimum resolution. After the scan is executed, scan data is transmitted from the multi-function device 5 to the mobile device 3 via the wireless LAN. When the scan application 42 of the mobile device 3 receives the scan data from the multi-function device 5, the scan application 42 stores the scan data in the storage destination folder selected by the user.

(4-2) Push Scan Next, push scan for instructing scanning from the multifunction device 5 side will be described. Also in the multi function device 5, when a predetermined operation for scan execution is performed, a screen similar to the scan execution screen shown in FIG. 2B is displayed on the display unit 60 of the multi function device 5. The user can set various setting items in the state where the scan execution screen is displayed on the display unit 60 as in the case of the pull scan. As for the reading resolution, it is possible to select automatic setting as in the case of pull scanning. Various setting items may be set on the mobile device 3 side even in the case of push scan.

  With reference to FIG. 3B, an example of a sequence at the time of push scanning in the case where the automatic setting is selected as the reading resolution will be described. As shown in FIG. 3B, when the automatic setting is selected as the reading resolution in the multi-function device 5 and the scan start button is selected (tapped), a push scan notification is sent to the mobile device 3 via the wireless LAN. In addition, a notification that “automatic setting” is selected for the reading resolution is transmitted.

The OS 41 of the mobile device 3 activates the scan application 42 when the scan application 42 is not activated when the push scan notification is received from the multifunction device 5.
When the scan application 42 receives a push scan notification from the multifunction device 5, the scan application 42 transmits scan setting information and a scan instruction to the multifunction device 5. At this time, when the automatic setting is notified from the multi-function device 5 as the reading resolution setting information, the scan application 42 determines the optimum resolution as the reading resolution setting value as in the case of pull scanning. Send the set value.

  As a result, the multifunction device 5 performs scanning at the optimum resolution. After the scan is executed, the scan application 42 saves the scan data received from the multi-function device 5 in the save destination folder selected by the user.

(5) Optimal Resolution Determination Method Next, an optimal resolution determination method that is determined when the automatic setting is selected as the reading resolution will be described. As described above, when the scan image scanned by the multi-function device 5 is displayed on the mobile device 3, it is displayed with an initial display size corresponding to the reading resolution at the time of the scan.

As shown in FIG. 4A, when an original is scanned at a reading resolution of, for example, 600 dpi and when scanned at a reading resolution of 100 dpi, the initial display size when displayed on the mobile device 3 is 600 dpi. The scanned image is displayed in a relatively large size, and the scanned image scanned at 100 dpi is displayed in a relatively small size.

  After the scan image is displayed at the initial display size, the user can enlarge or reduce the display size as described above. For example, when the user performs an enlargement operation on a scanned image scanned at 600 dpi in order to display the image larger, the display size of the scanned image is enlarged from the initial display size as in the enlarged example 1 in FIG. To do. The enlarged example 1 shows an example in which the size is enlarged to 150% of the initial display size.

  On the other hand, when the user performs a reduction operation for a scan image scanned at 600 dpi in order to display the scan image smaller, the display size of the scan image is changed from the initial display size as in reduction example 1 in FIG. to shrink. The reduction example 1 shows an example in which the size is reduced to 20% of the initial display size.

  The same applies to a scanned image scanned at 100 dpi. For example, when a user performs an enlargement operation for a scanned image scanned at 100 dpi, the display size of the scanned image is enlarged from the initial display size as in the enlargement example 2 in FIG. To do. Enlargement example 2 shows an example in which the image is enlarged to 300% of the initial display size.

  On the other hand, when the user performs a reduction operation for a scan image scanned at 100 dpi in order to make the display smaller, the display size of the scan image is changed from the initial display size as in the reduction example 2 in FIG. to shrink. The reduction example 2 shows an example in which the size is reduced to 50% of the initial display size.

  The fact that the user has performed an enlargement operation on the initial display size means that the reading resolution at the time of scanning is lower than the user's needs, and it is more appropriate for the user to scan at a higher reading resolution. If it is displayed from the beginning (as the initial display size) in the display size after the user performs the enlargement operation, it is expected that the user can view the surface without performing the enlargement operation.

  Specifically, in FIG. 4A, when an enlargement operation as in Enlargement Example 1 is performed on a scanned image scanned at 600 dpi, scanning with a resolution higher than 600 dpi meets the user's needs. It can be said that. Also for a scanned image scanned at 100 dpi, if an enlargement operation is performed as in Enlargement Example 2, it can be said that scanning with a resolution higher than 100 dpi matches the user's needs.

  On the other hand, the fact that the user has performed a reduction operation on the initial display size means that the reading resolution at the time of scanning is high for user needs, and it is more appropriate for the user to scan at a lower reading resolution. If the display is performed from the beginning with the display size after the reduction operation by the user (as the initial display size), it is expected that the user can browse the surface without performing the reduction operation.

  Specifically, in FIG. 4A, when a reduction operation as in reduction example 1 is performed on a scanned image scanned at 600 dpi, scanning with a resolution lower than 600 dpi meets the user's needs. It can be said that. Also for a scanned image scanned at 100 dpi, if a reduction operation as in Reduction Example 2 is performed, it can be said that scanning with a resolution lower than 100 dpi meets the user's needs.

  Therefore, the scan application 42 of the present embodiment refers to the table of FIG. 4B on the basis of the user's enlargement or reduction operation when displaying the scan image for each scan image. To decide. The table in FIG. 4B is a table in which an enlargement ratio or reduction ratio from the initial display size is associated with a resolution change rate indicating how much the reading resolution should be changed from the resolution at the time of scanning. For example, an enlargement / reduction ratio of 120% (that is, enlargement) is associated with an increase in resolution of 10%. This means that the fact that the display size has been enlarged to 120% means that the value that is inherently suitable as the reading resolution is 10% higher than the resolution at the time of scanning.

  However, in this embodiment, the individual resolution is not always determined by referring to the table when an enlargement or reduction operation is performed. In the present embodiment, the reflection button 18 is displayed at the bottom of the display unit 16 while the scan image is displayed on the display unit 16. When the reflection button 18 is tapped by the user, referring to the table based on the difference between the display size when the tapping is performed and the initial display size, that is, the enlargement ratio or reduction ratio from the initial display size, The individual optimum resolution is determined.

  FIG. 5 shows an example of the scan data stored in the folder and the individual optimum resolution for each scan data. In the example of FIG. 5, the folder 01 and the folder 02 are illustrated as the save destination folders. Of these, the scan data A and B are stored in the folder 01. In the folder 02, three pieces of scan data X, Y, and Z are stored. In addition, an optimum resolution is individually associated with each save destination folder. The optimum resolution for each folder will be described later.

  The scan data A stored in the folder 01 is sent to the multi-function device 5 with the optimum resolution setting value (100 dpi in this example) at that time when the automatic automatic setting is selected as the reading resolution. Scanned by the machine 5 at a reading resolution of 100 dpi. The scan data A is enlarged by the user when the scanned image is displayed on the mobile device 3, and is greatly enlarged (for example, about 300%) from the initial display size (size corresponding to 100 dpi). The reflection button 18 is tapped in the state of being enlarged. According to the table, the resolution change rate with respect to the enlargement rate at that time is increased by 100% (the numerical example is not shown in FIG. 4B). Therefore, the individual optimum resolution for the scan data A is set to 200 dpi, which is 100% higher than 100 dpi at the time of scanning.

  The scan data B stored in the folder 01 is sent to the multi-function device 5 as the optimum resolution setting value (300 dpi in this example) at that time when the automatic setting is selected as the reading resolution. Scanned by the machine 5 at a reading resolution of 300 dpi. Further, when the scan image is displayed on the mobile device 3, the scan data B is reduced by the user and reduced from the initial display size (a size corresponding to 300 dpi) (for example, about 50 to 60%). The reflection button 18 is tapped in a reduced state. The resolution change rate with respect to the reduction rate at that time is 30% lower according to the table (the numerical example is not shown in FIG. 4B). Therefore, the individual optimum resolution for the scan data B is set to 210 dpi, which is 30% down from 300 dpi at the time of scanning.

  Each time the scan image of the scan data is displayed on the display unit 16 and the reflection button 18 is tapped, the scan application 42 determines the individual optimum resolution of the scan data with reference to the table as described above, and Set (save) in association with the scan data.

  Furthermore, each time the scan application 42 determines the individual optimum resolution for any one of the scan data, it calculates the average value of each individual optimum resolution for all the scan data in the folder where the scan data is stored. To do. Then, the average value is stored in association with the folder as the optimum resolution corresponding to the folder.

  For example, in the case of the folder 01, the individual optimum resolutions of the two scan data A and B are 200 dpi and 210 dpi, respectively. Therefore, for the folder 01, 205 dpi, which is the average value of the two individual optimum resolutions, is linked as the optimum resolution. In the case of the folder 02, the individual optimum resolutions of the three scan data X, Y, and Z are 660 dpi, 540 dpi, and 600 dpi, respectively. Therefore, for the folder 02, 600 dpi, which is the average value of the three individual optimum resolutions, is linked as the optimum resolution.

  When the automatic setting is selected as the reading resolution and the scan application 42 transmits the setting value of the reading resolution together with the scan instruction to the multi-function device 5, the scan application 42 sets the optimum resolution associated with the folder selected as the save destination folder. The corresponding resolution is set as the optimum resolution, and the set value is transmitted to the multi function device 5. Specifically, the resolution closest to the optimum resolution among a plurality of types of reading resolutions that can be handled by the multi-function device 5 is determined as the optimum resolution.

  For example, when the automatic selection is selected as the reading resolution by the user and the folder 01 is selected as the storage destination, 205 dpi is associated with the folder 01 as the optimum resolution. On the other hand, in the present embodiment, the resolution that can be supported by the multi-function device 5 is one of 100 dpi, 200 dpi, 300 dpi, 600 dpi, 1200 dpi, and 2400 dpi. Therefore, in this example, the scan application 42 transmits the set value to the multi-function device 5 with 200 dpi, which is the resolution closest to the optimal resolution (205 dpi), as the optimal resolution.

(6) Processing Contents of Scan Application The processing contents of the scan application 42 executed by the CPU 21 of the mobile device 3 will be specifically described with reference to the flowcharts of FIGS. The CPU 21 of the mobile device 3 reads and executes the program of the scan application 42 shown in FIG. 6 from the storage unit 22 when an application activation operation is performed by the user or when a push scan notification is received from the multi-function device 5. .

  When the processing of the scan application 42 of FIG. 6 is started, the CPU 21 determines whether or not the scan application 42 has been activated by a push scan notification from the multi-function device 5 (ie, determination of activation factor) in S10. If it is not the activation by the push scan notification, that is, if the application is activated by the user operation on the mobile device 3, the process proceeds to S20. In S20, a menu screen (see FIG. 2A) is displayed on the display unit 16.

  In S30, it is determined whether or not “execute scanning” is selected (tapped) by the user on the menu screen. If “scan execution” is selected, a pull scan process is executed in S70. The details of the pull scan processing are as shown in FIG.

  When the CPU 21 proceeds to the pull scan process of FIG. 7, the CPU 21 displays a scan execution screen (see FIG. 2B) on the display unit 16 in S110. In S120, it is determined whether or not the scan start button in the scan execution screen has been selected (tapped). If the scan start button has not been selected, it is determined in S190 whether or not any of the setting item buttons (display area) has been selected (tapped).

  If any setting item button is selected in S190, in S200, the setting value of the selected setting item is changed, and the process returns to S120. In S200, for example, when reading resolution is selected as a setting item, a reading resolution setting screen (see FIG. 2C) is displayed, and a user's selection operation is awaited. When any resolution (including automatic setting) is selected by the user, the selected resolution is set as the reading resolution, and the scan execution screen is displayed again. Further, for example, when a save destination folder is selected as a setting item, a selection screen (not shown) for selecting the save destination folder is displayed, and a user's selection operation is awaited. When a folder is selected by the user, the selected folder is set as a save destination folder, and the scan execution screen is displayed again.

  If no setting item is selected in the scan execution screen in S190, it is determined in S210 whether the return button has been selected (tapped). If the return button is not selected, the process returns to S120. If the return button is selected, the pull scan process is terminated and the process returns to S20 (FIG. 6).

  If the scan start button is selected in S120, scan setting information to be transmitted (setting values such as reading resolution, file format, and save destination folder) is read in S130. In S140, it is determined whether or not the reading resolution is set to “automatic setting”. If it is not “automatic setting”, that is, if any resolution is selected, the process proceeds to S160. On the other hand, if “automatic setting” is selected, the process proceeds to S160 through the process of S150.

  In S150, the resolution closest to the optimum resolution associated with the save destination folder is determined as the optimum resolution to be used for scanning in the multifunction machine 5 among a plurality of types of reading resolutions that can be handled by the multifunction machine 5. The set value is set for transmission (overwriting the register in which the resolution setting value for transmission is written).

  In S160, a scan instruction and scan setting information (including the optimum resolution setting value) are transmitted to the multi-function device 5. As a result, the multifunction device 5 performs scanning at the transmitted optimal resolution, and scan data is transmitted from the multifunction device 5 to the mobile device 3.

  In S170, a process for receiving scan data from the multifunction machine 5 is performed. In S180, the scan data received from the multi-function device 5 is stored in a specified storage folder (selected by the user). After the process of S180, the process returns to S20 (FIG. 6).

  If “execution of scan” is not selected in S30, it is determined in S40 whether or not “view scan data” is selected (tapped) by the user on the menu screen. If “Browse Scan Data” is selected, a scan data display process is executed in S80. The details of the scan data display process are as shown in FIG.

  When proceeding to the scan data display process of FIG. 8, the CPU 21 accepts selection of scan data in S310. Specifically, a list of folders storing scan data is displayed. When any folder is selected, a list of scan data stored in the folder is displayed, and a selection operation by the user is awaited.

  In S320, it is determined whether any scan data is selected by the user. If the scan data is not selected by the user, it is determined in S400 whether or not the end of browsing is selected by the user (a browsing end button (not shown) is selected). When the browsing end is not selected, the process returns to S320, and when the browsing end is selected, the process returns to S20 (FIG. 6).

  If any scan data is selected in S320, an image of the selected scan data is initially displayed in S330 according to the reading resolution used when the image is scanned by the multi-function device 5. The size is displayed on the display unit 16. In S340, it is determined whether or not the user has performed an enlargement operation or a reduction operation on the scanned image displayed at the initial display size. If the enlargement or reduction operation is not performed, the process proceeds to S360. If an enlargement or reduction operation has been performed, the display size of the scanned image is changed (enlarged or reduced) according to the operation content in S350.

  In S360, it is determined whether or not the reflection button 18 (see FIG. 4A) has been tapped. When the reflection button 18 is not tapped, the process proceeds to S400. When the reflection button 18 is tapped, the resolution change rate is acquired based on the enlargement / reduction rate from the initial display size in S370. Specifically, the resolution change rate is acquired with reference to the table illustrated in FIG.

  In S380, the individual optimum resolution is updated based on the resolution change rate acquired from the table. Specifically, as described above, a value obtained by increasing or decreasing the reading resolution at the time of scanning according to the resolution change rate is determined as the individual optimum resolution and updated. In S390, based on the updated individual optimum resolution, the average value of the optimum resolution linked to the save destination folder is recalculated and overwritten. As a result, the new optimum resolution (average value) reflecting the updated individual optimum resolution is linked to the save destination folder. After the process of S390, the process proceeds to S400.

  Returning to FIG. 6, if “Browse Scan Data” is not selected in S <b> 40, it is determined whether a push scan notification is received from the multi-function device 5 in S <b> 50. If the push scan notification has not been received, it is determined in S60 whether or not “end” has been selected (tapped) by the user on the menu screen. If “END” is not selected, the process returns to S20. When “end” is selected, the scan application 42 is ended.

  When the push scan notification is received in S50, the process proceeds to the push scan process in S90. If the activation factor determination in S10 determines that the activation is based on the push scan notification from the multifunction machine 5, the process proceeds to the push scan processing in S100. The push scan process of S90 and S100 is the same process, and the details are as shown in FIG.

  When the CPU 21 proceeds to the push scan processing of FIG. 9, in S410, the CPU 21 determines whether or not “automatic automatic setting” has been notified of the reading resolution from the multi-function device 5. If “automatic setting” has not been notified, the process proceeds to S430. When “automatic setting” is notified, in S420, among the plurality of types of reading resolutions that can be supported by the multi-function device 5, the resolution closest to the optimum resolution linked to the save destination folder is selected. 5 is determined as the optimum resolution to be used in the scan in step 5, and the setting value is set for transmission (overwriting the register in which the resolution setting value for transmission is written). The storage folder may be notified from the multi-function device 5 or may be configured on the mobile device 3 side.

  In S430, scan setting information to be transmitted is read. In S440, a scan instruction and scan setting information (including the setting value of the optimum resolution described above) are transmitted to the multi-function device 5. As a result, the multifunction device 5 performs scanning at the transmitted optimal resolution, and scan data is transmitted from the multifunction device 5 to the mobile device 3. In S450, a process for receiving scan data from the multifunction machine 5 is performed. In S460, the scan data received from the multi-function device 5 is stored in a designated storage folder. After the process of S460, the process returns to S20 (FIG. 6).

(7) Effects of Embodiments, etc. According to the mobile device 3 of the present embodiment described above, when an image scanned by the multifunction device 5 is displayed on the mobile device 3, the display size is changed from the initial display size. In such a case, the individual optimum resolution is determined based on the degree of change (difference from the initial display size). As a result, when the scan instruction is subsequently transmitted to the multi-function device 5 and the resolution setting is set to the automatic setting, the optimal resolution setting value reflecting the determined individual optimum resolution is transmitted. Is done. Therefore, the mobile device 3 can instruct the multi-function device 5 to scan at an appropriate reading resolution (optimum resolution) according to the user of the mobile device 3 and the size of the display unit 16.

  For example, when a scan image is displayed small on the mobile device 3 due to scanning at a low reading resolution and the display size is too small for the user, the user performs an enlargement operation such as pinch out to display the display size. Is expected to expand. In that case, when the display size is enlarged from the initial display size, the optimum resolution is increased accordingly. Therefore, after that, scanning can be performed at a higher appropriate reading resolution, and a scanned image can be displayed in a larger size.

  On the other hand, when the scanned image is displayed largely on the mobile device 3 due to scanning at a high reading resolution and a part of the image protrudes from the display area of the display unit 16, the user displays the entire scanned image. As described above, it is expected that the display size is reduced by performing a reduction operation such as pinch-in. In that case, when the display size is reduced from the initial display size, the optimum resolution also decreases accordingly. Therefore, after that, scanning can be performed with a lower appropriate reading resolution, and a scanned image can be displayed with an appropriate size.

  In the present embodiment, the initial display size when the scanned image is displayed on the mobile device 3 is a display size corresponding to the reading resolution at the time of scanning. When the user performs an enlargement / reduction operation on the scanned image displayed at the initial display size, the optimum resolution is updated according to the operation content (and the reading resolution at the time of scanning is updated). ing.

  On the other hand, when displaying the scan image on the mobile device 3, for example, a method of displaying the entire scan image so that it fits perfectly in the entire display area of the display unit 16 is conceivable. That is, a method of uniformly displaying a scanned image on the entire screen regardless of the reading resolution at the time of scanning is conceivable. However, with such a method, it is difficult to set the reading resolution at the time of scanning to an appropriate value.

  For example, when the reading resolution is low and the scanned image is displayed roughly on the entire screen and is difficult to see, the user considers scanning at a higher reading resolution after the next time. However, it is difficult for the user to determine what specific reading resolution should be used. Further, for example, if the display size on the mobile device 3 is made to fit perfectly on the entire screen even though the reading resolution is too high, the user cannot recognize that the reading resolution is too high. That is, even though a lower reading resolution is sufficient, the user cannot recognize it. Therefore, it is expected that the user will continue to scan with the reading resolution that is too high after that, and the amount of scan data increases more than necessary, and the storage area of the storage unit 22 is compressed.

  On the other hand, in the mobile device 3 of the present embodiment, the scan image is displayed on the mobile device 3 with an initial display size corresponding to the reading resolution at the time of scanning, and the optimum resolution is updated according to subsequent enlargement / reduction operations by the user. Is done. Therefore, the reading resolution can be efficiently led to an appropriate value without bothering the user.

  The individual optimum resolution of the scan data is determined by the enlargement / reduction ratio with respect to the initial display size corresponding to the reading resolution at the time of scanning. Specifically, when the display size is enlarged from the initial display size, by setting the individual optimum resolution to a value larger than the resolution at the time of scanning, it is possible to specify a larger reading resolution in the subsequent scanning, and as a result The scanned image can be displayed with a larger initial display size. On the contrary, when the display size is reduced from the initial display size, by setting the individual optimum resolution to a value smaller than the resolution at the time of scanning, it is possible to indicate a smaller reading resolution in the subsequent scanning, and as a result, Scanned images can be displayed with a small initial display size.

  In this embodiment, for each scan data storage destination folder, the optimum resolution is obtained by averaging the individual optimum resolutions of the scan data saved in the folder, and the optimum resolution is linked to the folder. When the scan instruction and the scan setting information are transmitted from the mobile device 3 to the multi-function device 5, the optimum resolution is set to the resolution closest to the optimum resolution associated with the folder selected as the save destination folder. The set value of the correct resolution is transmitted to the multi-function device 5. Therefore, it is possible to appropriately and easily instruct the optimum resolution to the multi-function device 5.

[Other Embodiments]
(1) The table shown in FIG. 4B is merely an example. As for how to determine the individual optimum resolution for the enlargement / reduction ratio from the initial display size, including whether to use a table or not, As long as the resolution can be determined so as to change in the direction of lowering the resolution, various methods can be adopted.

  (2) The initial display size when the scan image is displayed on the display unit 16 of the mobile device 3 may be determined in consideration of the resolution of the display unit 16. For example, even if the reading resolution at the time of scanning is the same, the initial display size may be reduced as the resolution of the display unit 16 is higher, and conversely, the initial display size may be increased as the resolution of the display unit 16 is lower. .

  (3) As the optimum resolution for each folder, the average calculation result of the individual optimum resolutions is not used as the optimum resolution as it is, but the optimum resolution to be finally transmitted to the multifunction device 5 (that is, a plurality of types that can be handled by the multifunction device 5 The resolution closest to the average calculation result) may be determined as the optimum resolution and associated with the folder.

  (4) It is not essential to employ an average calculation of the individual optimum resolutions of the stored scan data as a method for determining the optimum resolution for each folder. As long as the individual optimum resolution of the stored scan data can be reflected, the optimum resolution may be determined by other methods.

  (5) It is not essential to determine (link) the optimum resolution for each folder individually. For example, the optimal resolution may be determined by performing an operation (for example, an average operation) based on the individual optimal resolutions of all the scan data stored in the mobile device 3. In addition, the optimum resolution can be determined by various methods based on the stored scan data.

  (6) Application of the present invention is not limited to application to the mobile device 3. The present invention can be applied to various information processing terminals other than the mobile device 3.
