However, the apparatus and method disclosed in the above publication have the following problems.
The method disclosed in Japanese Patent Laid-Open No. 5-28995 is intended only to quickly display cells outside the currently displayed range by specifying an approximate position in the entire table. No special consideration is given to the display of each column when the size of the image is reduced. As a result, there is a problem in that a person cannot recognize the contents of each column during reduction.

  In the method proposed in Japanese Patent Laid-Open No. 5-80967, there is a problem that when the image is reduced, the specific contents of each column cannot be understood according to the reduction rate. That is, this method improves the reaction speed by converting to information that can be easily displayed by a computer, such as only a single font or frame, instead of the information that should be displayed. As a result, when information is displayed at high speed, a part of the information is lost, resulting in a problem that the contents of the original information cannot be understood.

  The method proposed in Japanese Patent Laid-Open No. 2001-312686 changes the contents of each column to uniquely identifiable information such as color at the time of reduction, which is good for intuitive grasping, but the specific difference is not known. There is a problem.

<First Embodiment>
Referring to FIG. 1, display device 400 according to the present embodiment includes an input operation unit 401, an external storage unit 402, a CPU (Central Processing Unit) 403, a display control unit 404, a display unit 405, A program memory 406, a data memory 407, a transmission / reception unit 408, and a database 409 are included.

  The input operation unit 401 receives operations such as enlarging / reducing the table and tabular data. The CPU 403 controls each unit and performs necessary calculations. The display control unit 404 outputs data to the display unit 405 based on the instruction of the CPU 403 according to the user's instruction input to the input operation unit 401, and enlarges / displays the table by the display program operated by the CPU 403. Display the reduction result. The data memory 407 stores tabular data and data characteristic definitions. The tabular data is data displayed in tabular format on the display unit 405, obtained from the external storage unit 402, and expanded in the data memory 407. The tabular data may be obtained from the database 409 via the transmission / reception unit 408 via the network, or may be obtained by inputting tabular data from the input operation unit 401.

  Here, the definition of data characteristics will be described. In order for the display control unit 404 according to the present embodiment to display a table on the display unit 405, the definition of the data characteristics needs to be determined in advance. This definition may be uniquely defined, but in the present embodiment, it is stored in the data memory 407 as internal data of the table.

  With reference to FIG. 2, the table data stored in data memory 407 according to the present embodiment will be described. FIG. 2A is a table showing data stored in the data memory 407 according to the present embodiment. In a normal state, it is displayed on the display unit 405 in this state. FIG. 2B shows a state displayed on the display unit 405 by the CPU 403 controlling the display control unit 404.

  With reference to FIG. 3, the definition of the data characteristics of the table shown in FIG. 2A stored in data memory 407 according to the present embodiment will be described. The CPU 403 reduces the number of display characters in each cell based on this data characteristic definition.

  The data property definition includes information on the presence / absence of the data property definition, information on the usage state of the data property, row reduction information, information on the column reduction method, and information on the enhancement method.

  Information about the presence or absence of a data property definition indicates whether or not there is a data property definition. The information on the usage status of the data characteristics indicates whether or not the currently displayed table data is displayed using the data characteristic definition described here.

  The row reduction information indicates whether or not to reduce each row. According to FIG. 2, in the present embodiment, since the first line is an item name such as “name”, “height”, and “weight”, “do not delete”. Since the second and subsequent lines are various data, it is “deleted”.

  The information on the column reduction method represents the method of reducing the number of display characters for each column with respect to the row whose row reduction information is “reducing”. That is, since the data in the first column is “name”, “name is deleted”. Since the data in the second column is “height”, “the most significant digit is deleted”. Since the data in the third column is “weight”, “the decimal part is deleted”. Here, a method for reducing the number of display characters of individual data, that is, content information will be described. Since the content information of the data in the first column is data of a name, only the last name of the first and last names may be displayed as display information. Usually, there are few people with the same surname in one table, so that the space required for display can be halved while specifying the surname. Since the content information of the data in the second column is adult height data, it is realistic to consider the range as 100 cm or more and less than 200 cm. In the case of such data, the highest level is always 1. Thus, if the most significant 1 of each data is deleted and the last two digits of data are displayed as display information, the data can be simply reduced to 2/3. Since the content information of the data in the third column is adult weight data, the numbers after the decimal point do not make a big difference. In such data, the content of the original data can be identified and distinguished from other data, even if the decimal point is reduced and displayed as display information.

  In these cases, the data is highlighted so that it can be seen where it was reduced, that is, the name is displayed with a bold line on the right side of the cell, the height data is displayed with a bold line on the left side of the cell, and the weight data Displaying the right side of the cell with a bold line is convenient because it makes the data easier to see. The information on the emphasis method represents the emphasis method for each column with respect to the row whose row reduction information is “reducing”. That is, since the data in the first column is “name”, “the right end of the cell is displayed with a bold line”. Since the data in the second column is “height”, “the left end of the cell is displayed with a bold line”. Since the data in the third column is “weight”, “the right end of the cell is displayed with a bold line”.

  Such control in the display device 400 is realized by computer hardware and software executed by the CPU 403. Generally, such software is stored and distributed in a recording medium such as an FD (Flexible Disk) or a CD-ROM (Compact Disk-Read Only Memory), read by the external storage unit 402, and stored in the program memory 406. The Alternatively, it is obtained from the database 409 via the network via the transmission / reception unit 408. Of course, it may be burned into the program memory 406 from the beginning. The CPU 403 executes the software read by these methods. The hardware itself shown in FIG. 1 is general. Therefore, the most essential part of the present invention is software recorded on a recording medium such as FD or CD-ROM.

  Referring to FIG. 4, the program executed by CPU 403 has the following control structure with respect to the display of the table.

  In step 701 (hereinafter, step is abbreviated as S), the CPU 403 reads tabular data. In step S <b> 702, the CPU 403 controls the display control unit 404 to display the read tabular data on the display unit 405. After displaying the table, the CPU 403 stores the tabular data from the data memory 407 to the external storage unit 402 or the database 409 via the network. Storage in the database 409 is performed by controlling the transmission / reception unit 408.

  In step S <b> 703, the CPU 403 waits for an operation instruction from the user in the input operation unit 401. In step S <b> 704, the CPU 403 confirms the instruction content from the user, and determines whether the instruction is an enlargement / reduction operation instruction. If it is determined that the instruction is an enlargement / reduction operation (YES in S704), the process proceeds to S708. If not (NO in S704), the process proceeds to S705.

  In step S <b> 705, the CPU 403 confirms the content of the instruction and determines whether the instruction is a calculation rule replacement operation instruction. If it is determined that the instruction is an operation rule replacement operation instruction (YES in S705), the process proceeds to S706. If not (NO in S705), the process proceeds to S707. In S706, CPU 403 performs a replacement operation for the instructed calculation rule. In S707, CPU 403 performs an operation corresponding to the user's instruction content.

  In S708, CPU 403 determines whether or not the reduction ratio exceeds a threshold value. If it is determined that the threshold value has been exceeded (YES in S708), the process proceeds to S710. If not (NO in S708), the process proceeds to S709. In step S709, the CPU 403 performs simple reduction / enlargement that is not accompanied by data deletion.

  In step S710, the CPU 403 confirms the instruction content and determines whether the operation is a reduction operation. If it is determined that the operation is a reduction operation (YES in S710), the process proceeds to S711. If not (NO in S710), the process proceeds to S721.

  In step S711, the CPU 403 determines whether the tabular data has a data characteristic definition. If it is determined that there is a data characteristic definition (YES in S711), the process proceeds to S712. If not (NO in S711), the process proceeds to S720. In S712, CPU 403 reads the data characteristic definition. In S713, CPU 403 performs reduction and highlighting of the number of display characters of each cell based on the read data characteristic definition.

  In S <b> 714, the CPU 403 sets “Done” in the data property use column in the data property definition stored in the data memory 407. In S720, CPU 403 redisplays the tabular data on display unit 405 using display control unit 404.

  In S721, the CPU 403 determines whether or not the data characteristic definition is currently being used. If it is determined that the data characteristic definition is used (YES in S721), the process proceeds to S722. If not (NO in S721), the process proceeds to S720.

  In S722, CPU 403 uses display control unit 404 to restore the number of display characters of each cell displayed on display unit 405 and cancel the highlighted display. In S723, the CPU 403 sets “not yet” in the data property definition use field in the data property definition stored in the data memory 407.

  An operation of display device 400 based on the above-described structure and flowchart will be described.

  The CPU 403 reads the tabular data (S701). When the data is read, the CPU 403 controls the display control unit 404 to display the read tabular data on the display unit 405 (S702).

  When the tabular data is displayed, the CPU 403 waits for an operation instruction from the user in the input operation unit 401 (S703). When there is an operation instruction, the CPU 403 confirms the content of the instruction from the user and determines whether the instruction is an enlargement / reduction operation instruction (S704). In this case, since it is determined that the instruction is an enlargement / reduction operation (YES in S704), CPU 403 determines whether the reduction rate exceeds a threshold value (S708). In this case, since it is determined that the threshold value has been exceeded (YES in S708), CPU 403 checks the instruction content and determines whether or not the operation is a reduction operation (S710). In this case, since it is determined that the operation is a reduction operation (YES in S710), the CPU 403 determines whether or not the tabular data has a data characteristic definition (S711). In this case, since it is determined that there is a data characteristic definition (YES in S711), CPU 403 reads the data characteristic definition (S712).

  When the data characteristic definition is read out, the CPU 403 reduces the number of display characters and highlights each cell based on the read data characteristic definition (S713). When the number of display characters in each cell is reduced, the CPU 403 sets “done” in the data property use column in the data property definition stored in the data memory 407 (S714). When the setting is completed, the CPU 403 redisplays the tabular data on the display unit 405 using the display control unit 404 (S720).

  As described above, the display device according to the present embodiment uses the data characteristic definition and the category structure definition of the tabular data, and is partly used for distinguishing from other data unique to the individual data of the table. Display only. In general, even if the display is extremely reduced, even the frame of the table itself cannot be understood. If you don't even know the table frame itself, you won't be able to see the contents of each column in the table. If the contents in each column cannot be confirmed, there is no point in reducing the display. On the other hand, in the present embodiment, the compression method of the display information in each column is changed according to the characteristics of the data displayed in each column of the table. As a result, when the entire table is reduced and displayed, necessary data can be displayed larger and the contents of the original data can be specified. Furthermore, since the information showing the relationship between the individual data of the table and a part thereof is displayed, the user can easily grasp the difference. As a result, it is possible to realize a reduced display of a table in which the user can recognize the contents.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described. In the present embodiment, paying attention to the category structure of the table data, the number of frames itself is reduced.

  The data memory 407 of the display device 400 according to the present embodiment stores the table data shown in FIG. 5 and the category structure definition shown in FIG. 6 instead of the data according to the first embodiment. Other hardware configurations are the same as those in the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  The table data stored in the data memory 407 of the display device 400 according to the present embodiment will be described with reference to FIG. FIG. 5A is a table showing data stored in data memory 407 according to the present embodiment. In a normal state, it is displayed on the display unit 405 in this state. FIG. 5B shows a state displayed on the display unit 405 by the CPU 403 controlling the display control unit 404. In this case, monthly data on the number of products sold is changed to quarterly data and displayed. Since a quarter is composed of three months, the number of tables can be reduced to 1/3 by changing monthly data to quarterly data. Incidentally, it is convenient to highlight data so that it can be seen which cells belong to the same classification before reducing the number of frames. In the present embodiment, cells from January to March, April to June, July to September, and October to December are displayed surrounded by bold lines.

  With reference to FIG. 6, the category structure definition of the table of FIG. 5A stored in data memory 407 according to the present embodiment will be described. In order for the display control unit 404 according to the present embodiment to display a table on the display unit 405, the category structure definition of the table needs to be determined in advance. Although this definition may be uniquely defined, in the present embodiment, a predetermined calculation is performed between cells based on the category structure definition stored in the data memory 407, and the number of rows or columns is determined. Reduce at least one of the numbers.

  The category structure definition includes information on the presence / absence of the category structure definition, information on the usage status of the category structure, information on the classification and emphasis method in the row direction and the column direction, and information on calculation rules between the cells. .

  The information on the presence / absence of the category structure definition indicates whether there is a category structure definition. The information on the usage status of the category structure indicates whether or not the currently displayed table data is displayed using this category structure definition.

  The classification in the row direction represents whether or not the group in the row direction of each cell is grouped as one category, and if grouped, the group classification and the group emphasis method. In FIG. 5 (A), the first line is “product sales” and item names such as “A”, “B”, and “C”, which are the product names, so the classification is “out of structure” and the emphasis method is “ None ”. The second row is data on the number of sales of each product in April, which is classified as “Structure (1)” as one of the first quarters from April to June. The third row is data on the number of sales of each product in May. This is also classified as “Structure (1)” as one of the first quarters. The fourth row is data on the number of sales of each product in June. This is also classified as “Structure (1)” as one of the first quarters. The second to fourth rows so far are the same “structure (1)”, and the emphasis method is “surround the cell with a thick line”. Similarly, each of the 5th to 7th rows is “Structure 2” as one of the second quarters as a classification, and the emphasis method is “surround the cell with a thick line”. Each of the 8th to 10th lines is “Structure (3)” as one of the third quarters as a classification, and the emphasis method is “surround the cell with a thick line”. Each of the eleventh row to the thirteenth row is “structure (4)” as one of the fourth quarters as a classification, and the emphasis method is “surround cells by bold lines”. Information on the column direction classification and enhancement method is as follows.

  The column direction classification indicates whether or not each cell group in the column direction is grouped as one category, and if grouped, the group classification and the group emphasis method. In FIG. 5A, since the first column has item names such as “product sales”, “January”, “February”, etc., the classification is “out of structure” and the emphasis method is “none”. With respect to this table data, there is no classification having the same structure from the second column onward, all of them are separated, and the emphasis method is “none”.

  The calculation rule information between cells is calculated by applying a predetermined calculation rule between cells of the same classification based on the information described above, and reducing and highlighting at least one of the number of rows or the number of columns. It is information for. In the case of the present embodiment, the default (standard setting) is “simple sum”, and there is no classification to which a special calculation rule is applied. Therefore, in the case of the product “A”, the sum “198” of the sales number “115” in “January”, the sales number “38” in “February”, and the sales number “45” in “March” is calculated. .

  With reference to FIG. 7, another example of table data that can be displayed by display device 400 according to the present embodiment will be described. When displaying the home run data of a baseball player's individual, the number of frames in the table can be reduced by changing it to the home run data of the team. At this time, as in the case of FIG. 5, the cells are highlighted so as to know which cells belong to the same classification before the reduction of the number of frames, that is, A (1) to A (9), B (1) to B ( 8), C (1) to C (8), D (1) to D (8), E (1) to E (9), F (1) to F (9) cells are surrounded by thick lines Displaying with is convenient because it makes the data easier to see. Also in this case, the category structure definition according to the case of FIG. 6 is required.

  Referring to FIG. 8, the program executed by display device 400 according to the present embodiment has the following control structure with respect to table display.

  In S715, the CPU 403 determines whether or not the tabular data has a category structure definition. If it is determined that there is a category structure definition (YES in S715), the process proceeds to S716. If not (NO in S715), the process proceeds to S720.

  In S716, CPU 403 reads out the category structure definition stored in data memory 407. In S717, CPU 403 performs a predetermined calculation between cells based on the category structure definition read in S716.

  In S718, CPU 403 reduces the number of cells based on the result of the calculation performed in S717, and displays the result of the calculation. In S 719, the CPU 403 sets “Done” in the category structure use column in the category structure definition stored in the data memory 407.

  In S724, CPU 403 determines whether the category structure definition is currently used. If it is determined that the category structure definition is currently being used (YES in S724), the process proceeds to S725. If not (NO in S724), the process proceeds to S720. In step S725, the CPU 403 controls the display control unit 404 to restore each cell displayed on the display unit 405 to the original state and cancel the highlight display. In S 726, the CPU 403 sets “not yet” in the category structure definition use field in the category structure definition stored in the data memory 407.

  In S730, CPU 403 controls display control unit 404 to display read tabular data on display unit 405. At this time, when the category structure definition is stored in the data memory 407, it is highlighted.

  Other processing flows are the same as those in the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  An operation of display device 400 based on the above-described structure and flowchart will be described.

  When the CPU 403 reads data (S701), the CPU 403 controls the display control unit 404 to display the read tabular data on the display unit 405 (S730). In this case, since the category structure definition is stored in the data memory 407, it is highlighted.

  When the tabular data is displayed, the CPU 403 determines whether there is a category structure definition in the tabular data through the processing of S703 to S710 (S715). In this case, since it is determined that there is a category structure definition (YES in S715), CPU 403 reads the category structure definition stored in data memory 407 (S716).

  When the category structure definition is read, the CPU 403 performs a predetermined calculation between cells based on the category structure definition (S717). When the predetermined calculation is performed, the CPU 403 reduces the number of cells based on the result of the calculation performed in S717 and displays the calculation result (S718).

  When the calculation result is displayed, the CPU 403 sets “completed” in the category structure use column in the category structure definition stored in the data memory 407 (S719). When “completed” is set in the category structure use column, the CPU 403 redisplays the tabular data on the display unit 405 using the display control unit 404 (S720).

  As described above, the display device according to the present embodiment uses the data characteristic definition and the category structure definition of the tabular data, and calculates the result of calculating those cells instead of the plurality of cells of the table data. indicate. Thereby, when the entire table is reduced and displayed, necessary data is displayed larger, and the contents of the original data can be grasped sensuously from the information representing the calculated result. Furthermore, the user can easily grasp the relationship between a plurality of cells and the result of calculating those cells. As a result, a display device that allows the user to recognize the contents can be provided.

  In S717, if the data is valid for the data in the table, that is, if the user can properly grasp the original data in the table, the arithmetic mean is calculated without using the arithmetic sum as the predetermined calculation rule. It may be used. As a result, it is possible to provide a display device that allows the user to recognize the content more.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
