[2] Operation [2-1] Operation Example 1
FIG. 5 is a flowchart showing the process flow of the image processing apparatus 10. In step S101, the processor 152 stands by until the user sets an original (for example, a large-sized original) on the image processing apparatus 10 and instructs scan processing. In this embodiment, a large-sized document includes, for example, those conforming to the JIS standard (A0 size original, A1 size original, etc.) and those not conforming to the standard (roll paper etc.).

  In this embodiment, the UI unit 154 of the image processing apparatus 10 or the UI unit 354 of the user terminal 30 is used for the scan processing instruction from the user. When the UI unit 154 of the image processing apparatus 10 is used, the processor 152 of the image processing apparatus 10 displays the menu screen of the image processing apparatus 10 on the UI unit 154, and the user uses the screen displayed on the UI unit 154. Instructs execution of various processes. On the other hand, when the UI unit 354 of the user terminal 30 is used, the processor 152 of the image processing apparatus 10 transmits data representing the menu screen to the user terminal 30, and the processor 352 of the user terminal 30 receives the data from the image processing apparatus 10. The menu screen is displayed on the UI unit 354 in accordance with the received data. In this case, the user uses the menu screen displayed in the UI unit 354 to instruct execution of various processes. When execution of the process is instructed, the user terminal 30 transmits data indicating the content of the user's operation to the image processing apparatus 10, and the processor 152 of the image processing apparatus 10 receives the data from the user terminal 30, Detects scan processing instructions. If it is detected that the scan process has been instructed (step S101; YES), the processor 152 proceeds to the process of step S102.

  In step S102, the processor 152 controls the image reading unit 156 to execute a scan process. That is, the processor 152 causes the image reading unit 156 to read the image of the document set in the image processing apparatus 10. The read image data is generated in accordance with preset setting values. The setting value indicates, for example, the resolution of the image data or the file format. For example, when 600 dpi is set as the resolution and JPEG (Joint Photographic Experts Group) is set as the file format, a 600 dpi JPEG format file is generated.

  In step S103, the processor 152 determines whether or not the image data representing the document read by the image reading unit 156 can be stored in a predetermined memory area (hereinafter referred to as "memory area M1"). This determination is made based on, for example, the data amount of the image data or the file format. In this embodiment, the processor 152 determines that the storage process is executable when the data amount and / or the file format of the generated image data satisfy a predetermined condition. For example, when a large-sized document is read, the amount of image data may be too large to be stored in the memory area M1. In this case, it is determined that the image data can not be stored in the memory area M1. As another example, in the case where, for example, a large-sized document is read, the size of image data may exceed the upper limit value of the set file format standard. For example, when JPEG is specified as the file format, the image is read when the horizontal width of the read document exceeds 2722 mm, which is the upper limit value of JPEG, or when a large magnification or large size is specified. If the data becomes large, the image data can not be saved as JPEG. In this case, it is determined that the read image data can not be stored in the memory area M1.

  When it is determined in step S103 that the image data can be stored in the memory area M1 (step S103; YES), the processor 152 proceeds to the process of step S104. On the other hand, when it is determined that the data can not be stored (step S103; NO), the processor 152 proceeds to the process of step S109.

  In step S104, the processor 152 acquires the resolution of the display device (UI unit 154, UI unit 354, etc.) which is the display destination of the preview image. In this embodiment, when the UI unit 154 is used for the scan processing instruction, the UI unit 154 is set as the display destination of the preview image. On the other hand, when the UI unit 354 of the user terminal 30 is used for the scan processing instruction, the UI unit 354 is set as the display destination of the preview image. When the UI unit 154 is the display destination of the preview image, the processor 152 reads out information indicating the resolution supported by the UI unit 154 from a predetermined memory. On the other hand, when the UI unit 354 is the display destination of the preview image, the processor 152 performs a process of inquiring the user terminal 30 about the resolution of the UI unit 354. In this case, the user terminal 30 transmits the information indicating the resolution supported by the UI unit 354 to the image processing apparatus 10 in response to the inquiry from the image processing apparatus 10, and the image processing apparatus 10 receives the information from the user terminal 30. Obtain the resolution by receiving the information.

  In step S105, the processor 152 generates, as preview image data of the generated image data, preview image data of a resolution equal to or lower than the resolution acquired in step S104. In this embodiment, if the resolution of the generated image data is higher than the resolution acquired in step S104, the processor 152 drops the preview image data in which the resolution of the generated image data is reduced to the acquired resolution. Generate For example, when the resolution of image data scanned and stored in a predetermined storage is 600 dpi, and the resolution of the UI panel is 100 dpi, preview image data in which the resolution of the image data is reduced to 100 dpi is generated . If the resolution of the generated image data is equal to or less than the resolution of the display device, the process of generating preview image data is not performed. In this case, the image data of the read document is used as preview image data as it is.

  In step S106, the processor 152 supplies the preview image data generated in step S105 to the display device, and causes the display device to display the preview image. When the UI unit 154 is the display destination of the preview image, the processor 152 outputs the preview image data to the UI unit 154. On the other hand, when the UI unit 354 of the user terminal 30 is the display destination of the preview image, the processor 152 transmits the preview image data to the user terminal 30, and instructs the user terminal 30 to display the preview image.

  FIG. 6 is a diagram illustrating a preview screen to be displayed. The preview screen A1 exemplified in FIG. 6 includes a preview image area A11 in which a preview image is displayed, buttons B12 for changing the display mode of the preview image, B13,..., A save button B21, a cancel button B22, and a setting change button B23, Etc. While the preview image is displayed, the user operates the UI unit 154 (or the UI unit 354) to issue a storage instruction or setting change of the image data. When instructing storage of image data, the user presses the save button B21. On the other hand, when changing the setting, the user presses the setting change button B23. Thus, in the state where the preview image is displayed, the processor 152 receives a setting change or a storage instruction by the user.

  It returns to the explanation of FIG. When the storage instruction is issued by the user (step S107; storage instruction), the processor 152 proceeds to the process of step S108. On the other hand, when the setting has been changed by the user (step S107; setting change), the processor 152 proceeds to the process of step S111.

  In step S108, the processor 152 performs a process of storing the image data of the read document in a predetermined storage in accordance with the instruction of the user.

  In step S109, the processor 152 causes the display panel to display an error message that the storage processing of the image data can not be executed. Further, at this time, the processor 152 performs processing for presenting the setting parameter to be changed to the user by displaying on the display panel a setting change screen in which storage processing of the image data can be executed. For example, if the amount of image data is too large to store in the memory, even if the processor 152 displays a setting change screen for changing the resolution of the image data or a setting change screen for changing the color to monochrome. Good. Also, for example, when a large-sized document is read, if the size of the document is larger than the upper limit of the specified value of the file format, the processor 152 may display a screen for changing to another file format.

  The user performs an operation of changing the setting using the UI unit 154 (or the UI unit 354). If it is determined in step S110 that the setting has been changed by the user (step S110; YES), the processor 152 proceeds to the process of step S111. On the other hand, when it is determined that the setting has not been changed (step S110; NO), the processor 152 proceeds to the process of step S113.

  In step S111, the processor 152 changes the setting regarding the image data generated by the image reading unit 156 according to the information output from the UI unit 154 (or the UI unit 354) operated by the user. In this embodiment, for example, the resolution of the image data is reduced, or the file format is changed. In step S112, the processor 152 applies image processing to the image data to be stored according to the changed setting. For example, when the setting is changed to reduce the resolution, the processor 152 controls the image processing unit 157 to perform image processing for changing the resolution of the image data. In addition, when the setting change to change the file format is performed, the processor 152 controls the image processing unit 157 to change the file format of the image data. After completing the image processing of step S112, the processor 152 returns to the processing of step S103, and determines whether storage processing of the image data subjected to the image processing is executable.

  On the other hand, when it is determined in step S110 that the setting has not been changed (step S110; NO), the processor 152 cancels the execution of the process instructed in step S113, and ends the process.

  In this embodiment, after the setting is changed on the scan resetting screen, the image data with the designated setting is regenerated with respect to the scanned original image data, and the preview image is displayed when it is determined that storage is possible. As a result, the user can confirm the image image as a result of the setting change, and the storage of the image data confirmed by the preview display is guaranteed. Therefore, it is not necessary to rescan the document again due to an error or the like.

  Furthermore, on the preview confirmation screen after the scan re-setting, the setting can be further changed as necessary, and the image data can be regenerated and the preview can be confirmed. Specifically, as shown in steps S107 to S112 in FIG. 5, in the state where the preview image is displayed, image processing is performed according to the accepted setting change every time the setting change is accepted by the user. Image processing is performed on the image data.

  Further, since the UI screen of the operation unit of the image processing apparatus or the like is for setting, the resolution of the screen is generally low and the display area is also narrow. For this reason, when displaying a preview image on the UI panel of the image processing apparatus, even if it is intended to display a high resolution image, it is not possible to perform preview display with an image quality higher than the resolution of the UI screen. In addition, it may take time to display a high resolution image and the operability may be poor. On the other hand, in this embodiment, the resolution of the image data to be stored is not necessary for the preview image displayed on the preview screen, and therefore, the resolution of the UI panel to be displayed is converted based on the image data to be stored. In general, since the resolution of the UI panel is low, the preview image data is small, and the time until the preview display is shortened. Further, by matching with the resolution of the UI, even if the resolution is low, the preview display is performed without deterioration such as the image being crushed.

[2-2] Operation example 2
Next, another operation example of this embodiment will be described. In this operation example, the image processing apparatus 10 operates in accordance with one operation mode selected from a plurality of operation modes including an image quality priority mode in which image quality is prioritized and a size priority mode in which size is prioritized. First, the user sets a document (for example, a large-sized document) on the image processing apparatus 10, and performs setting operation related to scan processing using the operation screen displayed on the display device (UI unit 154 or UI unit 354), Instructs scan processing.

  FIG. 7 is a diagram illustrating a setting screen displayed on the display device. In the example of FIG. 7, “color mode”, “reading resolution”, “original quality” and “output file format” are set. As "color mode", "full color", "gray scale (256 gradations)", "monochrome (2 values)", "monochrome pseudo gradation (2 values)", "red black (2 values)" and "red black" One of the values such as "pseudo gradation (binary)" is selected by the user. As the “reading resolution”, one of resolution values such as “150 dpi”, “200 dpi”, “300 dpi”, “400 dpi” and “600 dpi” is selected by the user. As the "image quality of the document", one of the values such as "text / line drawing" and "text / photo" is selected by the user. As the "output file format", the user selects one of the values such as "single page TIFF", "multipage TIFF", "single page PDF" and "multipage PDF".

  FIG. 8 is a flowchart illustrating the flow of processing performed by the image processing apparatus 10. When a user sets an original (for example, a large-sized original) on the image processing apparatus 10 and instructs scan processing, in step S201, the processor 152 controls the image reading unit 156 to execute scan processing. That is, the processor 152 causes the image reading unit 156 to read the image of the document set in the image processing apparatus 10.

  FIG. 9 is a view exemplifying a screen displayed on the display device during the scanning process. In the example of FIG. 9, the storage destination of the image data, the file name, the setting value of the scan setting, and the like are displayed. The image data is generated in accordance with setting values set by the user. For example, when 600 dpi is set as the resolution and JPEG (Joint Photographic Experts Group) is set as the file format, a 600 dpi JPEG format file is generated. When the scan setting is not made by the user, the default value is referred to.

  It returns to the explanation of FIG. In step S202, the processor 152 determines whether the operation mode is the "image quality priority mode" or the "size priority mode". The image processing apparatus 10 has an “image quality priority mode” and a “size priority mode” as operation modes. The “image quality priority mode” is a mode in which the image quality is prioritized over the size (size) of the image of the image data to be stored. The “size priority mode” is a mode in which the size of an image is prioritized over the quality of image data to be stored. The operation mode may be set by user operation, or a preset default value may be referred to. In step S202, when the "image quality priority mode" is selected, the processor 152 proceeds to the process of step S203. On the other hand, when the “size priority mode” is selected, the processor 152 proceeds to the process of step S211.

  In step S203, the processor 152 determines whether the generated image data can be stored in a predetermined memory area M1. This determination process is the same as the process of step S103 in FIG. 5, and is determined based on, for example, the data amount of the image data and the file format. For example, when a large-sized document is read, the amount of image data may be too large to be stored in the memory area M1. In this case, it is determined that the image data can not be stored in the memory area M1.

  When it is determined in step S203 that the image data can be stored in the memory area M1 (step S203; YES), the processor 152 skips the process of step S204 and proceeds to the process of step S205. On the other hand, when it is determined that the data can not be stored (step S203; NO), the processor 152 proceeds to the process of step S204.

  In step S204, the processor 152 performs processing of changing the size of the image to a storable size without changing the resolution of the image data (while maintaining the high resolution). That is, when the “image quality priority mode” is selected, the processor 152 performs a process of reducing the size of the image of the image data generated by the image reading unit 156 without waiting for the user to change the setting. . After completing the process of step S204, the processor 152 proceeds to the process of step S205.

  On the other hand, when the “size priority mode” is selected, the processor 152 proceeds to the process of step S211. In step S211, the processor 152 determines whether the generated image data can be stored in a predetermined memory area M1. This determination process is the same as the process of step S203, and is determined based on, for example, the data amount of the image data and the file format. For example, when a large-sized document is read, the amount of image data may be too large to be stored in the memory area M1. In this case, it is determined that the image data can not be stored in the memory area M1.

  When it is determined in step S211 that the image data can be stored in the memory area M1 (step S211; YES), the processor 152 skips the process of step S212 and proceeds to the process of step S213. On the other hand, when it is determined that the data can not be stored (step S211; NO), the processor 152 proceeds to the process of step S212.

  In step S212, the processor 152 changes the resolution to generate image data that can be stored without changing the size of the image data. That is, when the “size priority mode” is selected, the processor 152 lowers the resolution of the image data generated by the image reading unit 156 without waiting for the user to change the setting.

  In step S213, the processor 152 determines whether storable image data can be created. For example, since the document is a large size document and the size of the image is large, even if the resolution is set to the minimum value, the image data may not be storable in the memory area M1. In that case, it is determined that storable image data can not be created. If it is determined that the image data can be created (step S213; YES), the processor 152 proceeds to the process of step S205. On the other hand, if it is determined that creation is not possible (step S213; NO), the processor 152 proceeds to the process of step S214.

  In step S205, the processor 152 performs a process of displaying a preview image. In this operation example, when the resolution of the generated image data is higher than the resolution of the display device (UI unit 154 or UI unit 354), the processor 152 drops the resolution of the generated image data to the acquired resolution. The preview image data is generated, and the generated preview image data is output to the display device. If the resolution of the generated image data is equal to or less than the resolution of the display device, the process of generating preview image data is not performed. In this case, the image data of the read document is used as preview image data as it is.

  FIG. 10 is a diagram illustrating a preview screen displayed on the display device. The preview image data is supplied to the display device, and the display device displays a preview screen including the preview image. While the preview image is displayed, the user operates the UI unit 154 (or the UI unit 354) to issue an instruction to store image data. When instructing storage of image data, the user presses the save button B31. Thus, in the state where the preview image is displayed, the processor 152 receives a storage instruction from the user.

  It returns to the explanation of FIG. If the storage instruction has been issued by the user (step S206; YES), the processor 152 performs a process of storing the image data in a predetermined storage. On the other hand, when the user does not issue a storage instruction (step S206; NO), the processor 152 proceeds to the process of step S214.

  In step S214, the processor 152 presents the setting parameter (for example, size setting) to be changed to the user by causing the display device to display a scan setting change screen on which storage processing of image data can be executed. I do. That is, processor 152 executes a process (step S214) for prompting the user to change the setting if the process of storing the image data in memory area M1 is not executable even if the change to lower the resolution is performed (step S212). Do. At this time, an error message indicating that storage processing of image data can not be performed may be displayed on the display device.

  FIG. 11 illustrates the setting change screen displayed on the display device in step S214. In the example of FIG. 11, a message indicating that the image file can not be created and a message prompting a change of settings is displayed. For example, when a large-sized document is read, if the size of the document is larger than the upper limit value of the specified value of the file format, the processor 152 may cause the display device to display a screen for changing to another file format. Also, for example, when the data amount of the image data is too large to store in the memory, the setting change screen for changing the resolution of the image data, the setting change screen for changing the color to monochrome, or the size of the image is changed. The processor 152 may display a setting change screen for setting on the display device. The user performs an operation of changing the scan setting using the UI unit 154 (or the UI unit 354).

  It returns to the explanation of FIG. If the user instructs to rescan (Step S215: YES), the processor 152 proceeds to the process of Step S216. On the other hand, when the rescan is not instructed (step S215; NO), the processor 152 proceeds to the process of step S218.

  In step S216, the processor 152 changes the scan setting regarding the image data generated by the image reading unit 156 in accordance with the content changed by the user. In this operation example, for example, the file format is changed. Further, the processor 152 performs image processing on the image data to be stored according to the changed scan setting. For example, when the setting change to change the file format is performed, the processor 152 controls the image processing unit 157 to change the file format of the image data. After completing the image processing of step S216, the processor 152 proceeds to the processing of step S217.

  In step S217, the processor 152 determines whether or not the regenerated image data can be stored in a predetermined memory area M1. This determination process is the same as the process of step S203. If it is determined in step S217 that the image data can be stored in the memory area M1 (step S217; YES), the processor 152 proceeds to the process of step S205. On the other hand, when it is determined that the data can not be stored (step S217; NO), the processor 152 returns to the process of step S215.

  In step S218, the processor 152 deletes the generated image data, and ends the processing.

  As described above, in this operation example, the image processing apparatus 10 is provided with the operation mode (image quality priority, size priority). The image processing apparatus 10 specifies settings that can be stored according to the operation mode from the read scan image, and generates an image file according to the specified settings. In the case of the “image quality priority mode”, the image processing apparatus 10 fixes the scanned image with the size of the read image as it is with high resolution (for example, 600 dpi) fixed based on the size of the image read by the image reading unit 156 Display the preview image if it can be saved. On the other hand, if storage is impossible, the image processing apparatus 10 converts the size into a storageable size and generates image data.

  On the other hand, in the case of the “size priority mode”, the image processing apparatus 10 does not change the size of the read image, generates image data with the setting value having the highest resolution among the storable resolution settings, and performs preview indicate. At this time, if there is no settable resolution, the image processing apparatus 10 displays an existing scan reset screen (FIG. 11 or the like).

  In this operation example, the image processing apparatus 10 changes the size or resolution of image data read in accordance with the setting value of the operation mode. As a result, the case (the case of executing the process of step S216) for displaying the re-setting screen (FIG. 11) is reduced, and the user operation required for the scan process is reduced. In addition, the scan processing can be easily performed without the user setting detailed parameters.
