Description

  The present invention relates to a data processing apparatus, method, and program.

  For example, in an audio device or the like, when a file to be reproduced is designated from the system microcomputer (control side), it is necessary to manage which file is reproduced on the system microcomputer side. For this reason, the system microcomputer has a data storage unit related to files and folders acquired by a DSP (Digital Signal Processor). Here, since the data acquisition capacity on the system microcomputer side is limited, the system microcomputer side sets a limit on the number of files / folders when storing data in the data storage unit.

  By the way, on the DSP side, the file / folder is acquired regardless of the restrictions on the system microcomputer side. For this reason, the system microcomputer cannot search for what the DSP acquires but cannot be acquired due to restrictions on the system microcomputer.

  Here, regarding the data search, there are methods disclosed in Patent Document 1 and Patent Document 2 in order to process and reduce the data acquired by the DSP so as to enable data search on the system microcomputer side.

JP 2007-156209 A JP 2007-102922 A

  For example, in Patent Document 1, data is grouped and stored in a memory with a large storage capacity, and when performing a search, a group is specified by a keyword or the like representing the characteristics of each group, and then the group is assigned to the group. A technique for performing a limited search is disclosed. According to this, it is possible to extract only the data belonging to the corresponding group from all the data acquired by the DSP and store it again in the system microcomputer side, and search for the data.

  Japanese Patent Application Laid-Open No. 2003-228561 discloses a technical content for copying or dividing a part of data such as a minimum title necessary for identifying data, storing it in a data storage unit, and retrieving it. According to this, it is possible to extract only a part of the data from all the data acquired by the DSP, store it on the system microcomputer side, and perform a search using the part of the data.

  However, in the method of performing grouping and copying or division of a part of data as seen in the above-mentioned Patent Documents 1 and 2 to compensate for the lack of storage capacity of the data storage unit, it is necessary to process the data. The acquired data cannot be used as it is.

  For example, in the case of an apparatus configuration that requires data processing, functional blocks and processes for processing data are required, which may increase the processing load on the entire apparatus.

  Or, since the types of data (titles, keywords, etc.) used by the user vary depending on the user, there is a possibility that even the data necessary for the user to search by data processing will be lost. There is. Therefore, it is desirable that such processing is not required and that efficient data retrieval can be performed even if the data acquisition capacity of the system microcomputer is small.

  The present invention has been made to solve such problems, and provides a data processing apparatus, method, and program capable of performing efficient data retrieval even when the data acquisition capacity of the system microcomputer is small The purpose is to do.

  When the present invention is viewed from the viewpoint of a data processing apparatus, the present invention relates to a storage means for storing data, a display means for displaying a predetermined number of information related to the data, and a page for constructing the data as a plurality of page groups. Of the pages constructed by the construction means and the page construction means, the page containing the data to be displayed by the display means is set as the central page, and the data included in the central page includes information on a predetermined number of data. For data contained in an adjacent page adjacent to the central page, information about the data equal to or greater than a predetermined number that can be displayed by the display means within a range that does not reach the stored number in the central page. Data storage means for storing.

  Further, when the present invention is viewed from the viewpoint of a data processing method, the present invention relates to a data storage means provided in the data processing apparatus in which the page construction means provided in the data processing apparatus constructs data as a plurality of page groups. Of the pages constructed by the page construction means, a page including data to be displayed by the display means for displaying the data included in the data processing device is defined as a central page, and data included in the central page Information about a predetermined number of data is stored, and the data included in the adjacent pages adjacent to the central page is the same as the predetermined number that can be displayed by the display means within a range not reaching the stored number in the central page. Alternatively, the same number or more of information related to the data is stored.

  Further, when viewed from the viewpoint of a program, the present invention is a function corresponding to page construction means for constructing data as a plurality of page groups in the information processing apparatus by installing the information processing apparatus, Of the pages constructed by the page construction means, the page containing the data to be displayed by the display means is a central page, and the data contained in the central page stores information on a predetermined number of data, For data included in adjacent pages adjacent to the central page, data that stores information on the data that is equal to or greater than the predetermined number that can be displayed by the display means within a range that does not reach the number stored in the central page. A function corresponding to the storage means is realized.

    According to the present invention, an efficient data search can be performed even if the data acquisition capacity of the system microcomputer is small.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block configuration diagram of a data processing apparatus according to an embodiment of the present invention (a diagram showing the invention in a schematic block configuration unlike the application example of FIG. 8).

  As shown in FIG. 1, the data processing apparatus according to the embodiment of the present invention includes a memory 1, a page construction unit 2, a data storage unit 3 in which data is stored, and data stored in the data storage unit 3. A search unit 4 for searching for data from within, a display unit 5 for displaying data searched by the search unit 4, input search information such as a search key into the search unit 4, and an operation of turning a page to be described later It is a data processing apparatus provided with the operation part 6 which performs.

  In the present invention, the storage area of the data storage unit 3 is divided into a plurality of parts, and each divided storage area is defined as a different page assigned with a serial number. The data stored in this page is extracted by the page construction unit 2 according to a predetermined rule (the predetermined rule will be described later), and a part of many files and folders are listed. It has become. That is, some of a large number of files and folders are stored in the page according to a predetermined rule.

  As described above, the present invention is characterized by a method of storing a part of the data acquired by the memory 1 in the data storage unit 3, and the data itself acquired by the memory 1 is not subject to any processing (grouping (patented). Document 1) is also characterized in that a part of data such as a title necessary for identifying data is not copied or divided (Patent Document 2).

  Here, the role of the page construction unit 2 and the role of the data storage unit 3 will be described in detail. The page construction unit 2 plays a role of performing page division for all data stored in the memory 1, and the data storage unit 3 stores a part of the data for which the page construction unit 2 has performed page division. It plays the role of storing in the site. At this time, the page construction unit 2 grasps the identification information of the data corresponding to the break for each page for all data stored in the memory 1 in advance, and the data storage unit 3 displays the page number (for example, the center page). When the page construction unit 2 is notified of the execution of the data storage by designating the page number, the page construction unit 2 stores a predetermined number of data in the page designated from the data storage unit 3 from the memory 1. The data is acquired and transferred to the data storage unit 3, and the data storage unit 3 stores the data transferred from the page construction unit 2 at a predetermined page position.

  Here, for example, in the data search in an audio device or the like, the operation / search using the operation unit 6 is performed in the horizontal direction (direction to move to another page in FIG. 4) or the vertical direction (in a specific page in FIG. 4). In general, it is the two directions of moving in (the direction in which the display unit 5 scrolls the page). Therefore, the feature of the embodiment of the present invention is that, in view of the fact that the acquisition of data in the currently designated page (center page) is likely to be performed in the vertical direction later, Get all the data.

  On the other hand, when searching or displaying data in other pages, the page is moved once in the horizontal direction and then moved in the vertical direction. Therefore, in pages other than the current center page, the page is configured with the minimum amount of data to be acquired, and when another page becomes the center page by the operation of the operation unit 6, a new vertical page is newly created. Get additional direction data. The present invention is characterized by this point.

  Hereinafter, the contents of the present invention will be sequentially described with reference to the drawings.

  In the example of FIG. 1, data (pages with serial numbers) stored in the data storage unit 3 is a part of data (a number of files, folders, etc.) stored in the memory 1. The storage capacity of 1 is larger than the storage capacity of the data storage unit 3, and it is assumed that all data stored in the memory 1 cannot be stored in the data storage unit 3.

  A display unit 5 and an operation unit 6 are connected to the search unit 4, and the user visually confirms information on the data displayed on the display unit 5 (information in a page with a serial number). be able to. Further, a page to be searched (referred to as a central page; a page currently displayed on the display unit 5 as shown in FIG. 5) can be designated from the operation unit 6 to the search unit 4. Furthermore, information necessary for a search such as a search key can be input from the operation unit 6 to the search unit 4.

  As the operation unit 6, for example, there are operation buttons for shifting information display and the like in the up-down direction and the left-right direction in the audio device, but other units may be used as the operation unit 6.

  FIG. 2 is a diagram showing all folders stored in the memory 1. Conventionally, the memory 1 acquires all the folders shown in FIG. 2 and searches for necessary data from all the acquired folders. In the example of FIG. 2, 72 folders AL-A001 to AL-A072 exist.

  FIG. 3 is a diagram illustrating a display example of the display unit 5. In the present embodiment, examples of the display unit 5 include a display unit (liquid crystal panel or the like) such as an audio device. The display unit 5 shown in FIG. 3 can display information (corresponding to data) regarding three folders at a time. In addition, the information regarding the folder in the page displayed on the display unit 3 is not limited to three, and may be one, two, or four or more.

  FIG. 4 is a diagram showing information about folders stored (classified) in a page in the memory 1. In the example shown in FIG. 4, the total number of pages is four. In addition, what consists of this all page respond | corresponds to a page group. In the example of FIG. 4, folder names are shown as information on all folders (classified) over all four pages stored in the memory 1. In this example, the user selects the page 1 as the central page by operating the operation unit 6. Therefore, the page construction unit 2 acquires information about the folder in the portion surrounded by the thick frame in the pages 1 to 4 and stores it in the data storage unit 3. In this storage (classification) process, no processing (grouping, copying, dividing, etc.) is performed on the data itself acquired by the memory 1.

  In FIG. 4, page 2 and page 4 are pages adjacent to page 1. That is, when a user who has searched for page 1 selects the next page, page 2 is displayed, and when the previous page is selected, page 4 is displayed.

  Here, in the present embodiment, the data storage unit 3 stores information on a predetermined number of folders for the central page that is the display target in the display unit 5, and the adjacent page adjacent to the central page is the central page. Information about the number of folders equal to or greater than the predetermined number that can be displayed on the display unit 5 is stored within a range that does not reach the storage number. Further, for pages other than the central page and the adjacent pages, information on the number of folders equal to or greater than the predetermined number that can be displayed by the display unit 5 is stored within a range that does not reach the number of adjacent pages stored.

  For example, in the present embodiment, the predetermined number of folders stored in the central page is the upper limit number that can be stored in the page. The number equal to or greater than the predetermined number that can be displayed on the display unit 5 is an integral multiple of the predetermined number that can be displayed on the display unit 5. Further, it is assumed that folders of pages in adjacent relations have continuity in each adjacent relation.

  That is, for the central page (page 1 in the example of FIG. 4) that is the data display target of the display unit 5, the page construction unit 2 acquires information on all folders existing on the page and newly sets the central page. Then, the data storage unit 3 stores the new central page in its own storage site. For the adjacent pages of the central page (pages 2 and 4 in the example of FIG. 4), the page construction unit 2 relates to the same number of folders that can be displayed by the display unit 5 or an integer multiple of the predetermined number. The information is acquired to newly construct an adjacent page, and the data storage unit 3 stores the new adjacent page in its own storage site.

  Further, for pages other than the central page and the adjacent page (page 3 in the example of FIG. 4), the page construction unit 2 has a predetermined number that can be displayed by the display unit 5 within a range that does not exceed the number of stored adjacent pages. The information about the number of folders equal to or the integer multiple of the predetermined number is acquired and another page is newly constructed, and the data storage unit 3 stores the new other page in its own storage part.

  A new page created based on such a rule (predetermined rule) is shown in FIG. In FIG. 5, in page 1, information related to all the folders existing in the page 1 (information related to 18 folders) is stored and a new page 1 is created, and in pages 2 and 4, 6 folders are related. Information is stored, and page 3 stores information about three folders.

  Note that the total number of pages and the number of pieces of information related to folders stored in the central page can be changed as appropriate according to the total number of folders. If the total number of pages is large, the number of pieces of information related to folders existing in the central page is small. On the other hand, if the total number of pages is small, the number of pieces of information related to folders existing on the central page increases.

  FIG. 5 also shows a state in which information about three folders is displayed on the display unit 5 at the same time as the new page as described above. In the example of FIG. 5, the user visually confirms information regarding the third folder from the top of page 1. Further, the user can visually check information on all folders in the page 1 by moving in the vertical direction by operating the operation unit 6.

  FIG. 6 shows a state when the user operates the operation unit 6 and selects, for example, “next page” from the state shown in FIG. By such a user operation, as shown in FIG. 6, page 2 becomes the central page, pages 1 and 3 become adjacent pages of the central page, and page 4 becomes the other page.

  In this user operation, the display unit 5 creates information about three folders from the top of page 2 that is an adjacent page before operation, which is created in advance from the display state related to page 1 that is the central page before operation. Is displayed. Subsequently, the data storage control unit 2 newly reconstructs pages for all pages based on the above-described method. As a result, with respect to page 2, which is the central page, the state is switched from a state in which only six pieces of information about folders exist to a state in which there are 18 pieces of information. Similarly, with respect to page 1, the state is switched from a state in which only 18 pieces of information about folders exist to a state in which there are 6 pieces of information. For page 3, the state is switched from the state where three pieces of information about the folder exist to the state where there are six pieces of information. For page 4, the state is switched from a state in which only six pieces of information about a folder are present to a state in which three pieces of information are present.

  As described above, in the embodiment of the present invention, particularly when the number of pages increases, the total amount of data related to pages stored in the data storage unit 3 can be significantly reduced. Further, since each newly constructed page has a limited amount of data related to the newly constructed page, the process of constructing each page can be performed at a very high speed.

  FIG. 7 is a diagram showing how the display jumps to the page specified by the user. In the example of FIG. 7, even when the display shifts to the page specified by the user, the transfer destination page n is related. By storing the information regarding the minimum necessary folder in the data storage unit 3, the information regarding the folder in the page n can be displayed immediately.

  In consideration of such page display jumps, it is desirable to acquire information on the minimum folder displayed on the display unit 5 for all pages other than the central page and the adjacent pages. However, in general, the frequency of such a page display jump operation is considered to be lower than the frequency of the operation of sequentially changing pages from the central page to the adjacent page, so the storage capacity of the data storage unit 3 is small. When the number is small, it is not always necessary to store information about the folder other than the central page and the adjacent page.

(Application example)
An application example of the data processing apparatus according to the embodiment of the present invention will be described with reference to FIG. FIG. 8 is a configuration diagram of the music playback device. 8 reproduces music data recorded on a CD (Compact Disc) and an MD (Micro Disk), as well as a memory card, a USB (Universal Serial Bus) memory, a hard disk (internal or external).
