Next, main functions of the image display device 1 configured as described above will be described. FIG. 2 is a block diagram showing the main functions of the image display device 1. As shown in FIG. 2, in the image display device 1, the CPU 2 functions as a program execution unit according to the image display program stored in the storage device 6. Image data stored in the storage device 6 such as PDF format and JPEG format, and document format data corresponding to various applications (hereinafter referred to as document data) are to be read. Note that the data to be read may be stored in the storage medium 9.

  The CPU 2 performs a reduced image creation unit 21, a determination unit 22, a display image creation unit 23, a display control unit 24, an instruction reception unit 25, and a control unit based on an instruction of an image display program in the storage device 6. 26, a status information adding unit 27, a keyword searching unit 28, a non-searched file detecting unit 29, and an OCR unit 30.

  The reduced image creation unit (reduced image creation means) 21 reads a file (document data, image data, etc.) stored in the storage medium 9 or the storage device 6 and creates a reduced image representing the contents of each file. It is further preferable to read out property information (information such as the file name of the file and the type of application used to open the file) associated with each file and reflect the information on the reduced image.

The determination unit (determination unit, file state determination unit) 22 determines whether or not a file stored in the storage device 6 or the storage medium 9 is accompanied by text data obtained by converting the file into text. . Further, the discriminating unit 22 adds (1) data forming the main body of the file (hereinafter referred to as main body data) to the file stored in the storage device 6 or the storage medium 9, and text data obtained by converting the file into text. It is determined whether it is included or (2) the text data is not attached to the file and the text data obtained by converting the file into text is not included. For example, if the file data format is PDF format data, word processor application data, etc., text data may be included in the body data of the file. It is intended to determine the state.

A display image creation unit (display image creation unit, status display image creation unit) 23 displays that text data is attached when the determination unit 22 determines that text data is attached to the file. Create an image (an image with a small data size that becomes part of a thumbnail image). Further, the display image creation unit 23 determines (1) the text data is attached to the file determined by the determination unit 22, (2) the text data is included in the body data of the file, (3) the file A file status display image that displays each status such that no text data is attached to the file and the main data of the file does not contain text data (an image with a small data size that forms part of the thumbnail image). Also create. These display images are created using sample image data in the image display program.

  The display control unit (display control unit, search result display control unit, detection result display control unit) 24 is created by the reduced image creation unit 21 when the discrimination unit 22 determines that text data is attached to the file. The reduced image thus created and the display image created by the display image creation unit 23 are displayed on the display 7 as one thumbnail image. Further, if the determination unit 22 determines that the text data is not attached to the file, the display control unit 24 displays the reduced image created by the reduced image creation unit 21 as a thumbnail image.

  Further, when a file status display image is created by the display image creation unit 23, the display control unit 24 combines the file status display image and the reduced image created by the reduced image creation unit 21 into one thumbnail. The image is displayed on the display 7 as an image.

  In addition, the display control unit 24 displays a list of thumbnail images of files searched for by the keyword search unit 28 (to be described later) as containing the keyword specified by the operator, and further, detected by the non-search file detection unit 29. The thumbnail images of the files that were not searched are displayed as a list.

  The instruction receiving unit 25 receives an instruction based on an operation of the input device 3 (mouse pointer or the like) by the operator. In this embodiment, a part of the thumbnail image, that is, any one of the reduced image part and the display image part is displayed. An instruction as to whether it has been designated or a keyword input desired by the user at the time of keyword search execution by the keyword search unit 28 is accepted.

  When the display image portion is designated by the instruction receiving unit 25 among the thumbnail images displayed on the display 7 by the display control unit 24, the control unit (control unit) 26 includes the contents of the text data attached to the file. Is displayed, and when the reduced image portion is designated by the instruction receiving unit 25, control is performed such as displaying the contents of data constituting the file body.

  When the determination unit 22 determines that text data is attached to the file, or when it is determined that the actual data text file of the file is included, the state information addition unit (state information addition unit) 27 Information indicating that text data is attached to or included in the file is added to the file property information or file name information.

  The keyword search unit (keyword search means) 28 searches whether the text data included in the file body or the text data accompanying the file includes the keyword input from the input device 3 by the operator. is there.

  The non-search file detection unit (non-search file detection means) 29 detects a file that has not been searched by the keyword search unit 28.

  An OCR (Optical Character Reader) unit 30 analyzes characters included in data read as an image by the scanner 10 and converts the characters into text data (text data). The OCR unit 30 adds the converted text data to the conversion source file, puts the converted text data into a conversion source file in a storage area different from the area where the conversion source file is stored. Relate to remember.

  Processing for creating a thumbnail image of a file stored in the storage device 6 will be described. FIG. 3 is a flowchart showing a process for creating a thumbnail image of a file stored in the storage device 6 or the like, FIG. 4A is a diagram showing a state in which a file list is displayed as a thumbnail on the display 7, and FIG. It is an enlarged view of an image. This thumbnail image is obtained by displaying the contents of each file in a small file size when displaying a list of files stored in the storage device 6 or the like. In the present embodiment, the thumbnail image is composed of a reduced image that is displayed by reducing the contents of the file, for example, and when the file is accompanied by text data, the file is accompanied by text data. And a display image indicating that the

  When the thumbnail image creation process is performed, the reduced image creation unit 21 reads the data of the file stored in the storage device 6 or the like (S1). At this time, when the file consists of a plurality of pages, the data of the first page is read out. The reduced image creation unit 21 creates a reduced image by reducing the image indicated by the read data to a predetermined size (S2). The determination unit 22 determines whether text data (for example, one converted by the OCR unit 30) is attached to the file for which the thumbnail image is to be created (S3). The determination of whether or not text data is attached by the determination unit 22 may be made based on whether or not text data is actually attached to the file, or information indicating the presence or absence of text data in the file. You may judge by whether it is accompanying. For example, the determination may be made based on whether the property information of the file includes information indicating the presence or absence of text data in the file.

  Here, when text data is attached to the file (YES in S3), the display image creating unit 23 creates a display image indicating that the text data is attached to the file (S4). The display control unit 24 places the generated reduced image data and the display image data when the display image is generated in the RAM 5 (image memory) as thumbnail image data (S5), and the thumbnail image. Is displayed on the display 7 (S6). The above processing is performed for each file recorded in the recording device 6 or the like.

  In this way, the display control unit 24 displays each file stored in the storage device 6 as a thumbnail image, as shown in FIG. For example, as shown in FIG. 4B, a file with text data converted by the OCR unit 30 is a thumbnail image that has been subjected to OCR processing and has text data attached. Displayed as part of. In FIG. 4B, the user is made to recognize that the text data accompanies the display image indicating the characters “OCR”.

  Next, a process for changing the display contents according to which part of the thumbnail image is designated by the operation of the input device 3 by the user will be described. FIG. 5 is a flowchart showing the processing. When the thumbnail image displayed as an icon is operated by the user on the input device 3, for example, when the mouse pointer is double-clicked, the data of the double-clicked file is started by opening an associated application. However, the image display program and the image display apparatus according to the present invention vary the contents of data to be displayed by changing the application to be activated depending on which part of the thumbnail image is designated. It has become.

  When the thumbnail image is designated by the user double-clicking the mouse pointer and the instruction is accepted, the control unit 26 determines which portion of the thumbnail image is designated by the operation (S11). When the reduced image portion indicating the contents of the file main data of the thumbnail image is designated (reduced image in S11), the control unit 26 activates an application associated with the file main data (S12). The body data of the file is opened using the application (S13).

  When the display image portion indicating that the text data is attached to the thumbnail image is designated (display image in S11), the control unit 26 activates the application associated with the text data (S14). The associated text data is opened using the application (S15).

  As a result, the user can select whether to open the file body data or the text data depending on which part of the thumbnail image is designated by the input device 3. For example, if the display image portion is designated, the text data can be directly opened by a simple operation, and the text data can be quickly accessed.

  Next, a description will be given of a process of giving information indicating that text data is attached to the file when text data is attached to the file. FIG. 6 is a flowchart showing the processing. Note that the same processing as the processing shown in FIG.

  When text data is attached to a file stored in the storage device 6 or the like, in order to indicate this state, information indicating that the text data is attached together with creation of the display image described above is property information of the file. You may make it add to. In this case, as shown in FIG. 6, when it is determined by the determination unit 22 that the text data is attached to the file (YES in S3), the state information addition unit 27, together with the creation of the display image (S4), Information indicating that the file is accompanied by text data (S21). In the process of S21, the state information adding unit 27 creates a new file name including a message (such as “OCR processed” character) indicating that the text data accompanies the file name. It may be.

  In the above description, when text data is attached to a file, information indicating that the text data is attached is added to the property information of the file together with creation of a display image (S21). Instead of performing the display image creation process (S21), only the process of adding information indicating that the text data is attached to the property information of the file may be performed.

  Next, a second embodiment of the thumbnail image creation process will be described. FIG. 7 is a flowchart showing the processing, FIG. 8A is a diagram showing a thumbnail image having a display image indicating that text data is attached to the file, and FIG. 7B is a main data of the file without text data attached. FIG. 5C is a diagram showing a thumbnail image having a display image indicating that no text data is included, and FIG. 8C is a diagram showing a thumbnail image having a display image indicating that text data is included in the main data of the file. . Note that the same processes as those shown in FIGS. 3 and 6 are denoted by the same reference numerals and description thereof is omitted.

  In the thumbnail image creation processing according to the second embodiment, a thumbnail image is created that includes a state display image that indicates in what form the keyword stored in the storage device 6 or the like is in a keyword searchable state. To do. In this process, the discrimination unit 22 discriminates in what format each file stored in the storage device 6 or the like is in a state in which a keyword can be searched, and the display image creation unit 23 performs the respective search. A state display image representing the discrimination result is created, and the display control unit 24 displays the state display image and the reduced image on the display 7 as thumbnail images.

For example, as shown in FIG. 7, the determination unit 22 (1) text data is attached to a file, (2) the body data itself of the file includes text data, (3) text data is stored in the file. Are not attached, and the main data of the file does not include text data (S31). Then, based on the determination result, the display image creating unit 23 creates respective file status display images indicating the contents of the above (1), (2), and (3) (S33, S34, S35). Thereafter, the state information adding unit 27 includes information indicating the file state in the property information of the file (S21).

  Then, the display control unit 24 places the reduced image data and the file state display image data in the RAM 5 (image memory) (S5), 8 (a), (b), and (c) as shown in FIG. A thumbnail image composed of a status display image and a reduced image is displayed on the display 7 (S6).

  In this way, the user can recognize whether the file stored in the storage device 6 or the like is in a state where the keyword search is possible and whether the file body data itself is searchable. . That is, whether the file body data is a file format that originally includes text data and can be searched by keywords, or the file body data is originally not searchable by keywords, but the OCR processing by the OCR unit 30 causes the text data to be searched. It is possible for the user to grasp whether or not the keyword search has been made possible.

  In the above description, after the processing of S33, S34, and S35, the state information adding unit 27 includes the property information of the file including information indicating that the file is accompanied by text data ( S21) It is also possible not to perform this process. Further, instead of the process of S21, a process of including the file status information in the file name may be performed.

  Next, a process for searching for whether or not a file stored in the storage device 6 or the like includes a user-specified keyword will be described. FIG. 9 is a flowchart showing the keyword search process, and FIG. 10 is a diagram showing an example of a display screen for displaying the keyword search result.

  When a keyword to be searched for is input by the user's operation of the input device 3 and the search instruction and the keyword are received by the instruction receiving unit 25 (YES in S51), the keyword search unit 28 is stored in the storage device 6 or the storage medium 9. It is searched whether or not the keyword is included in each file stored in (S52).

  Then, the keyword search unit 28 detects a file including the keyword input by the user (S53). When a search is performed by the keyword search unit 28, a keyword cannot be detected if text data is attached to a file stored in the storage device 6 or the like, or text data is not included in the main data of the file. The search file detection unit 29 also detects a file that does not contain text data and is not a search target from the file group that is the search target (S54).

  Then, the display control unit 24 causes the display 7 to display a list of each thumbnail image of the file including the keyword and each thumbnail image of the file that has not been searched (S55).

  As a result, files that are not included in the search target are displayed on the display 7 together with the file containing the keyword. The user can grasp whether the search result is in a certain situation.

  Further, if the keyword search process of FIG. 9 is performed after the thumbnail display process of FIG. 7, a file that is a keyword search target and a file that is not a keyword search target are mixed in the storage device 6 or the like. JPEG format data consisting of images of scenes, etc., based on thumbnail display, whether each file was not subject to keyword search because it was not OCR processed As described above, the user can grasp whether keyword search is impossible in the first place.

  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, the image display program according to the present invention is installed in a personal computer and used as an image display device. However, other devices can be used as long as the image display program can be installed. It can also be used as an image display device according to the present invention.
