A file management system 1 according to an embodiment of the present invention includes a multifunction peripheral (an example of an image reading apparatus) 2... And a personal computer (an example of an image display apparatus) 3. As shown in FIG. 1, the multifunction devices 2 and the personal computers 3 are connected by a communication cable 4 constituting a LAN (Local Area Network). The number of personal computers 3 and multifunction devices 2 is not particularly limited as long as it is one or more. The multifunction device 2 has a printer, a scanner, a facsimile function, and the like in addition to copying.

  Further, the control unit 20 functions as a scan data conversion unit 201, a property information detection unit 202, and a scan data transmission unit 203. A scan data conversion unit (scan data conversion unit) 201 converts the scan data read by the scanner unit 24 into a predetermined resolution different from the reading resolution. For example, when the scanning resolution of the scanner unit 24 is 600 dpi, the scan data conversion unit 201 converts the scan data read at the resolution to 200 dpi, 300 dpi, 400 dpi, etc., which are lower resolutions than the resolution. The converted scan data having the respective resolutions is stored in a predetermined area of the HDD 23. Note that each resolution converted by the scan data conversion unit 201 can be appropriately changed by the operation of the operation unit 28 by the user.

  The property information detection unit (property information detection unit) 202 is configured to detect the resolution and the data amount of each scan data for the scan data read by the scanner unit 24 and the converted scan data converted by the scan data conversion unit 201. Is detected and used as part of the property information indicating the characteristics of the scan data. The property information detecting unit 202 stores each property information in the predetermined area of the HDD 23 in association with the corresponding scan data.

  The scan data transmission unit 203 transmits the scan data before and after the conversion and the property information about the scan data to the personal computer 3 as necessary.

  An image memory 25 and an HDD 23 are connected to the control unit 20. The image memory 25 is used for temporarily storing scan data (original data) read by the scanner unit 24. The HDD 23 stores the scan data read by the scanner unit 24, file data and scan data transmitted from each personal computer 3, and each scan converted by the scan data conversion unit 201 as described above. Data and property information about these are stored in a predetermined area.

  The multifunction device 2 further includes an operation key 281 for the user to perform various settings on the multifunction device 2 and an operation panel 282 including an LCD or the like that displays the operation status of the multifunction device 2 to the user. A portion 28 is provided.

The display on the display panel 282 is controlled in order to notify the user of the document reading resolution by the scanner unit 24, the conversion resolution by the scan data conversion unit 201, and the operation status.

  The configuration of the personal computer 3 will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration of the personal computer 3. The personal computer 3 includes a control unit (control means) 31, a ROM 32 storing various operation programs, a RAM 33 used as an operation area of the control unit 31, and various types of data received from the multifunction device 2. HDD 34 capable of storing data, a display (display means) 35 comprising an LCD (Liquid Crystal Display), etc., a communication I / F 36 functioning as an interface for performing various data transmission / reception with the multifunction device 2 etc., and a user Input device (for example, a keyboard, a mouse pointer, etc.) 37 for inputting various operation instructions and the like. As the communication I / F 36, various data transfer means can be applied regardless of wired or wireless.

  The control unit 31 controls the operation of each part of the personal computer 3, and also functions as a display control unit 311, a resolution selection instruction receiving unit 312, an instruction transmission unit 313, and an instruction receiving unit 314. A display control unit (first display control unit, second display control unit) 311 displays the property information transmitted from the scan data transmission unit 203 of the multifunction device 2 on the display 35. In addition, the display control unit 311 (1) displays the resolution of each scan data on the display 35 based on the property information. (2) After the resolution is displayed, the resolution selection instruction reception unit 312 described later receives the resolution. Control is performed such that the data amount of the scan data is displayed on the display 35 together with the scan data corresponding to the resolution.

  When the resolution of each scan data is displayed on the display 35 by the display control unit 311, the resolution selection instruction receiving unit 312 receives an instruction for the user to select a desired resolution from these resolutions. This selection instruction is input by the operation of the input device 37 by the user and received by the resolution selection instruction receiving unit 312.

  The instruction transmission unit 313 transmits the resolution selection instruction received by the resolution selection instruction reception unit 312 to the multifunction device 2 via the communication I / F 36. When the display control unit 311 displays the content of the scan data on the display 35, the instruction reception unit (storage instruction reception unit) 314 receives a scan data storage instruction or the like including the amount of data. This save instruction is input by an operation of the input device 37 by the user, for example.

  In the control unit 31, the display control unit 311, the resolution selection instruction receiving unit 312, the instruction transmission unit 313, and the instruction receiving unit 314 may be individually configured with a circuit or the like, or in the ROM 32 or the HDD 34. The CPU may be configured to operate as the display control unit 311, the resolution selection instruction reception unit 312, the instruction transmission unit 313, and the instruction reception unit 314 in accordance with the stored image display program.

  Next, a description will be given of a first embodiment of a process for storing scan data read by the multifunction device 2 in the personal computer 3 in the file management system 1. FIG. 3 is a flowchart showing a process of storing scan data read by the multifunction device 2 in the personal computer 3 in the file management system 1, and FIGS. 4 to 7 show examples of display screens of the personal computer 3 when the scan data is stored. FIG.

  In the multifunction device 2, when a document reading instruction is input by the operation of the operation unit 28 by the user (YES in S1), the control unit 20 causes the scanner unit 24 to read a document to be read at the highest resolution, for example (S2). The read scan data is stored in the HDD 23 (S3). When the scan data is converted to a resolution other than the reading resolution, it cannot be converted to a resolution higher than the reading resolution. Therefore, the document reading resolution by the scanner unit 24 is set to the highest resolution, and the width of the resolution at which the scan data can be converted is widened. Yes. Further, the resolution at the time of reading the document by the scanner unit 24 can be appropriately changed by the operation of the operation unit 28 by the user, and can be scanned at the resolution desired by the user. If no document reading instruction is input from the user (NO in S1), S2 to S5 are skipped and the process proceeds to S6.

  Then, the scan data conversion unit 201 creates a plurality of scan data having a resolution lower than the resolution based on the scan data read at the high resolution (S4). That is, for example, if the scanning resolution of the scanner unit 24 is 600 dpi, the scan data conversion unit 201 creates scan data of 200 dpi, 300 dpi, 400 dpi, etc., which are resolutions lower than the resolution, before and after the conversion. Are stored in a predetermined area of the HDD 23. Each resolution created by the scan data conversion unit 201 can be appropriately changed by the operation of the operation unit 28 by the user, and scan data having a resolution desired by the user is created.

  After creating the scan data of each resolution, the property information detection unit 202 detects the data amount of the scan data of each resolution. That is, the property information detection unit 202 detects the resolution and data amount of each scan data as property information (S5). Each detected property information is stored in the HDD 23 along with each scan data. The original scan data before conversion is stored in the HDD 23 as basic scan data, and the converted scan data of another resolution is stored in the HDD 23 as preliminary second group scan data. When the file outline in the HDD 23 of the multifunction device 2 is displayed as a thumbnail or the like on the personal computer 3 based on a request from the personal computer 3 (for example, FIG. 4), basic scan data is used.

  When the personal computer 3 accesses the multifunction device 2 and the summary of each file in the HDD 23 of the multifunction device 2 is displayed on the display 35 in the state shown in FIG. When an operation of the device 37 (for example, an operation such as right-clicking a desired file with a mouse pointer) is performed and a desired file is designated (YES in SS1), the instruction transmission unit 313 instructs the multifunction device 2 The transmission of the resolution of the designated file is requested (SS2).

  In the MFP 2, when a resolution transmission request from the personal computer 3 is received by the control unit 20 via the network I / F 21 (YES in S6), the scan data transmission unit 203 causes the HDD 23 to accompany each scan data. Based on the stored property information, the resolution of each scan data before and after conversion is transmitted to the personal computer 3 (S7). Here, it is expressed that the resolution transmission request is transmitted from the personal computer 3 to the multi-function device 2 and the multi-function device 2 transmits the resolution to the personal computer 3. However, in this process, the personal computer 3 accesses the multi-function device 2. Thus, all processes for obtaining resolution are widely included. If there is no resolution transmission request from the personal computer 3 (NO in S6), the process of S7 is skipped.

  In the personal computer 3, when the resolution of each scan data is received from the multifunction device 2 via the communication I / F 36 to the control unit 31, the display control unit 311 displays a resolution list on the display 35 (SS3). That is, the resolution of the original scan data read by the scanner unit 24 of the multifunction device 2 is displayed by the scan data conversion unit 201 is displayed. From the user's point of view, it is displayed at what resolution the scan data read by the scanner unit 24 of the multifunction device 2 can be captured and stored in the personal computer 3. For example, as shown in FIG. 5, when the user designates a file with the name “conference”, a resolution list is displayed adjacent to the “conference” file.

  Here, when the user selects the desired resolution by moving the mouse pointer (input device 37) to the portion where the desired resolution is displayed and performing a left double click operation or the like (YES in SS4), the resolution selection instruction is accepted. The unit 312 accepts the selection, and the instruction transmission unit 313 requests the multifunction device 2 to transmit the scan data having the selected resolution and the data amount of the scan data (SS5).

  In the MFP 2, when the control unit 20 receives the scan data and data amount transmission request via the network I / F 21 (YES in S8), the scan data having the instructed resolution and the data amount (property information) Is read from the HDD 23, and the scan data transmission unit 203 transmits the read scan data and data amount to the personal computer 3 (S9). When the control unit 20 does not receive the scan data and data amount transmission request (NO in S8), the process of S9 is skipped.

  In the personal computer 3, when the control unit 31 receives the scan data and the data amount from the multifunction device 2 via the communication I / F 36, the display control unit 311 displays the received scan data and the data amount as shown in FIG. Is displayed on the display 35 (SS6). That is, the content of the scan data having the resolution selected by the user in SS4 is enlarged and displayed on the display 35 together with the data amount in a state larger than the thumbnail display.

  Here, when an instruction to save the enlarged scan data is input by the user's operation of the input device 37 and accepted by the instruction accepting unit 314 (YES in SS7), the control unit 31 is enlarged and displayed. The scan data having the resolution selected by the user, that is, the scan data received from the MFP 2 is stored in the HDD 34 (SS8). When the user inputs the scan data saving instruction, for example, when the user moves the mouse pointer (input device 37) to the enlarged display portion and performs a right click operation, the operation is performed near the enlarged display portion as shown in FIG. The menu M is displayed, which is performed by the user left-clicking the “Cut” display portion with the mouse pointer. If the scan data saving instruction is not input by the user (for example, by left-clicking “Close” in the operation menu M), the process returns to SS3 and the resolution list is displayed again (NO in SS7).

  After the scan data storage is completed, the instruction transmission unit 313 transmits a scan data storage completion notification to the multifunction device 2 (SS9). In the multifunction device 2, when the control unit 20 (scan data erasing unit, scan data organizing unit) receives the storage end notification via the network I / F 21 (YES in S10), the above-mentioned resolution stored in the personal computer 3 is determined. In other words, each scan data having a resolution other than the resolution is erased from the HDD 23 (S11). By this deletion, the amount of free data in the HDD 23 is increased. When the control unit 20 does not receive the storage end notification (NO in S10), the process of S11 is not performed and scan data having each resolution is left. In the process on the personal computer 3 side, if SS1 is NO, the process ends.

  Instead of the processing of S11, after transmitting the scan data to the personal computer 3, the control unit 20 (scan data saving unit, scan data organizing unit) leaves the original scan data read by the scanner unit 24 in the HDD 23, Scan data other than the scan data may be erased. In this case, since the scan data with the highest resolution remains in the HDD 23, it becomes possible to create scan data with a lower resolution again, and also when performing other image processing, the highest resolution. Since it can be performed based on the scan data, the utility value is high.

  By performing such a series of processes by the file management system 1, the user can grasp the amount of scan data when a certain original is read at a plurality of resolutions on the personal computer 3 side. Since the contents of the respective scan data having the respective resolutions are displayed largely on the display 35, the image quality of the scan data having the respective resolutions can be confirmed.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, in the above-described embodiment, in the processing by the file management system 1 shown in FIG. 3, when a desired file is designated by the user (YES in SS1), the personal computer 3 Only the resolution of each scan data before and after conversion is acquired (S7, SS3). At the time of this resolution acquisition, each scan data and each property information including the resolution and the data amount are acquired. When the desired resolution is selected later by the user (YES in SS4), the display control unit 311 uses the scan data already acquired and the data amount based on the property information as shown in FIG. Such display may be performed.

  In the embodiment shown in FIG. 3, when the desired resolution is selected by the user (YES in SS4), the personal computer 3 requests scan data having the resolution selected by the user from the multifunction device 2. However, at this time, thumbnail image data of the scan data may be acquired instead of the scan data. When the thumbnail image data is acquired in this way, in SS6, the received thumbnail image data and the data amount are displayed. In this way, the user can roughly grasp the content (image quality) of the scan data having the selected resolution, and can reduce the amount of data received from the multifunction device 3.

  In the above-described embodiment, the image reading apparatus according to the present invention is described as the multifunction device 2. However, the multifunction device 2 is merely an example of the image reading device, and the image reading device according to the present invention is used as the multifunction device 2. It is not intended to be limited. Similarly, in the above embodiment, the computer and the image display device according to the present invention are described as the personal computer 3, but the personal computer 3 is merely an example of the image display device, and the image display device computer according to the present invention, Is not intended to be limited to the personal computer 3.

  The configurations and processes shown in FIGS. 1 to 7 are merely examples, and the present invention is not limited to the configurations and processes shown above.
