Description

Specification

Data display device, data display program, and computer-readable recording medium recording data display program

Technical field

The present invention relates to a data display device, a data display program, and a computer-readable recording medium on which the data display program is recorded, and more particularly, to a data display device, a data display program, and a data display device that display data including a character string on a screen. The present invention relates to a computer-readable recording medium recording a data display program.

Background art

[0002] When displaying data including a character string, not all characters "J" may be displayed depending on the size of the display screen. One example is a list display of content data on a device capable of storing a large amount of data (for example, a hard disk recorder). Here, the “content” includes recording data of a recorded television program and image data recorded from a digital camera / video camera.

[0003] Hard disk recorders that store recording data reserved by the user in advance, data created by the user, recommended information, and the like have appeared. The reason for the appearance of such hard disks is that they can store large amounts of data. By the way, here, “recommended information” refers to the content collected by the recommended algorithm. “Recommended algorithm” refers to an algorithm that collects information according to the user's preference.

[0004] When using such a hard disk recorder that stores a large amount of various contents, it is essential that the user can easily identify each content and easily find the desired content.

[0005] Content information (information indicating the content of a content; a title is an example thereof).

When the list is displayed in (), all character information may not be displayed on the screen. This means that when a user searches for a content to be viewed from a large amount of content, the user can easily identify each content and easily search for the content desired by the user. It is a barrier to the situation. The reason is that if all text information is not displayed on the screen, the user will be able to identify the content. Also, there are two reasons why all character information is not displayed. The first point is that the number of characters in character information such as titles tends to be too large. The second point is that the display area of the screen and the number of displayed characters are limited.

[0006] On the other hand, if the display frame is enlarged to display all the character information, the listability deteriorates. The reason is that the number of contents that can be displayed on one screen is reduced. Further, when the displayed character size is reduced, the displayed character becomes <<. When the displayed character becomes <<, the user goes to << for information. Therefore, the number of characters can be adjusted based on the size of the display frame.

[0007] Specifically, Patent Document 1 discloses an information grasping device that can easily grasp the relationship between the entire information and detailed information that is a part thereof, and important information. This device first simply reduces the letter's number itself in the field. When the reduction ratio falls below a certain threshold, the device causes the characters and numerals that were displayed in multiple fonts to be displayed in a single font. Further, when the reduction ratio becomes equal to or smaller than another threshold value, the apparatus displays the positions of the characters and numerals in a rectangular shape. Further, when the reduction ratio becomes equal to or less than a predetermined threshold value, the apparatus displays the positions of the characters and numerals in a straight line. Finally, when the reduction ratio becomes equal to or less than a predetermined threshold, the apparatus displays only the frame. As a result, only the fact that it is a table is known.

[0008] Patent Document 2 discloses a display device that displays a small number of characters so as not to be displayed when the number of displayed characters is large. Since small characters are not displayed, the amount of information displayed by the display device is reduced. Since the amount of information to be displayed is reduced, the displayed contents are easier to see and understand.

[0009] However, as disclosed in Patent Document 1, when characters or numbers in a column are simplified / reduced, there is a problem that the contents of each column cannot be understood at the time of the reduction.

[0010] As disclosed in Patent Document 2, when a large number of characters are displayed and small characters are displayed without being displayed, data to be displayed may have the same character size. However, if the data is just text data (that is, there is no information indicating the size of a character in the first place), the above-described effect cannot be obtained. The reason is the font size Is determined whether or not to display based on the size of the image.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description of them will not be repeated.

Referring to FIG. 1, data display device 50 according to the present embodiment includes an input unit 52 and a CPU ( Central Processing Unit) 54, a memory 56, a magneto-optical disk drive 58, a display data storage unit 60, a keyword storage unit 62, a genre table 64, a character string storage unit 66, and a character number storage unit 68. And a display unit 70. Data display device 50 according to the present embodiment is a device that displays display data regardless of the type of input display data. “Display data” is data displayed on the display unit 70. Program data representing a recorded program (including a recommended program), image data taken with a video camera, schedule data representing a user's schedule, and recommended information are examples of display data. Here, the “recommended program” refers to a program recorded by the above-described recommended algorithm. "Recommended information" means information collected by the recommended algorithm.

The input unit 52 receives data such as display data, the maximum size of display data, the maximum number of characters capable of displaying display data, display instructions, and keywords. The “keyword” is data indicating a genre or a matter of interest to the user. The “display instruction” is an instruction to display a part of the character string data included in the display data based on the priority. The data display device 50 records a recommended program and collects recommended information by the above-described recommended algorithm based on the keyword received by the input unit 52. The input unit 52 includes an interface and a keyboard (neither is shown). The interface accepts input of system (not shown) force data (as described above) connected to the data display 50. The keyboard accepts user input of data (as described above). If there is a conflict between the input from the interface and the input from the keyboard, the data input from the keyboard takes precedence. The CPU 54 controls each part of the data display device 50. The CPU 54 is also a circuit that processes information necessary for the data display device 50 to display display data. The memory 56 temporarily stores information processed by the CPU 54. The magneto-optical disk drive 58 mounts a magneto-optical disk (hereinafter referred to as “M〇 (Magneto-Optical)”) 80. MO 80 stores a program for realizing data display device 50 according to the present embodiment. The display data storage unit 60 stores the display data received by the input unit 52. The keyword storage unit 62 stores the keyword received by the input unit 52. In the present embodiment, the keyword storage unit 62 stores the keyword together with the priority of the keyword. Genre Table 64 stores keywords that are displayed with priority. Keywords stored in the genre table 64 are classified by genre. The genre table 64 stores information indicating the genre (“drama”, “series”, “sports”, etc.) and the keyword that is prioritized for each genre (if the genre is a drama, “X episode” or “X ) Etc. are stored. As a result, the prioritized keywords are classified according to each of the keywords. If the character data described later represents these priority keywords, the priority of the character data increases. The character string storage unit 66 stores character data to be described later and data indicating the priority of the character data. If the “character string type” of the stored character data can be specified, the character string storage unit 66 stores data representing the “character string type” together with the character data. “Character string type” refers to a type that can be determined based on the content of character data. Time (a number followed by a “:”), date (a number followed by a “/”), channel (a number followed by “CH”) are examples of “string types”. The number-of-characters storage unit 68 stores the number of characters that the display unit 70 can display. The CPU 54 determines the number of characters that can be stored in the display unit 70. The number of characters that can be displayed on the display unit 70 is determined based on the maximum area that can be displayed on the input unit 52 and that can display display data. The display unit 70 displays display data.

The data display device 50 is realized by computer hardware and software executed by the CPU 54. Generally, such software is stored and distributed in a recording medium such as MO80, read out to a recording medium memory 56 by a magneto-optical disk drive 58 or the like, and executed by the CPU 54 described above. The computer hardware itself described above is common. Therefore, the most essential part of the present invention is software recorded on a recording medium such as MO80. Since the operation of the computer itself is well-known, detailed description thereof will not be repeated here.

Referring to FIG. 2 and FIG. 3, the program executed by data display device 50 has the following control structure regarding display of display data.

[0042] In step 100 (hereinafter, step is abbreviated as S), the CPU 54 sets the priority based on the information stored in the keyword storage unit 62, the genre table 64, and the character string storage unit 66. I do. The priority is set as a value such as “+2” or “_1”. Ah In addition, the CPU 54 sets the following items according to a user or system instruction. The first is whether to set the priority of character strings based on the content of metadata. The second matter is that sub-data (in this embodiment, “sub-data” is data that is independently displayed and data that is independently displayed among the data that constitute the display data) Sub-data may represent a single data or a group of data). The third item is metadata (“metadata” in this embodiment refers to character string data. However, “metadata” in this step refers to metadata included in the displayed subdata. ) To determine whether or not to determine the priority of the character string in the display data. However, the third item is set when displaying sub data together with display data.

[0043] In S102, input unit 52 receives an input of data. In addition, the CPU 54 stores the display data received by the input unit 52 in the display data storage unit 60. When there is a request to register a keyword, CPU 54 stores the keyword accepted by input unit 52 in keyword storage unit 62. Further, the CPU 54 identifies the type of the display data. When the type of display data belongs to a specific type (set in advance by the user) such as an electronic schedule book, the CPU 54 causes the display unit 70 to display the input display data.

In S104, CPU 54 determines whether or not there is a display instruction from the user or the system described above. If it is determined that there is a display instruction (YES in S104), the process proceeds to S106. If not (NO in S104), the process proceeds to S102.

In S106, CPU 54 determines the number of characters that can be displayed based on the maximum area for displaying the display data. This “maximum area for displaying display data” is received by the input unit 52. The CPU 54 determines the maximum area for displaying the display data, which is received by the input unit 52, as the size of the area for actually displaying the character data. However, if the input unit 52 receives the number of characters that can be displayed simultaneously instead of the maximum area, the CPU 54 determines the value received by the input unit 52 as the number of characters that can be displayed simultaneously among the characters represented by the character data. Determine the number of characters.

In S108, CPU 54 determines that the number of characters N of the display data is larger than the maximum number of characters L described above. Let's judge the power. If it is determined that the number of characters N is greater than the maximum number of characters L (YES in S108), the process proceeds to S110. If not (NO in S108), the process proceeds to S180.

In S110, CPU 54 decomposes character string data representing a character string from the display data received by input unit 52. The CPU 54 decomposes the character string data into character data for each clause, each representing at least one character, by morphological analysis. The CPU 54 stores the character data obtained by the decomposition in the character string storage unit 66. At the same time, the CPU 54 analyzes the “character string type” of the decomposed character string. When the “character string type” is analyzed, the CPU 54 also stores information representing the character string type in the character string storage unit 66. Further, the CPU 54 stores the priority (in this step, the priority of any character data is “0”) in the character string storage unit 66.

At S112, CPU 54 determines whether or not the display data is automatically collected data (recommended information, recommended programs, and the like). If it is determined that the data is automatically collected (YES in S112), the process proceeds to S114. If not (NO in S112), the process proceeds to S142.

At S 114, CPU 54 determines whether or not a keyword is stored in keyword storage section 62. If it is determined that the keyword is stored (YES in S114), the process proceeds to S116. If not (NO in S114), the process proceeds to S142

At S 116, CPU 54 determines whether or not the display data includes sub-data that can be displayed on display unit 70. If it is determined that sub data is included (YES in S116), the process proceeds to S118. If not (NO in S116), the process proceeds to S134.

In S 118, CPU 54 determines whether or not the sub data included in the display data includes metadata. If it is determined that metadata is included (YES in S118), the process proceeds to S120. If not (NO in S118), the process proceeds to S134.

At S 120, CPU 54 determines whether an unprocessed keyword exists in the keywords included in either the display data or the sub data. If it is determined that an unprocessed keyword exists (YES in S120), the process proceeds to S122. If so When the level is reached (NO in S120), the process proceeds to S132.

At S122, CPU 54 extracts one of the unprocessed keywords. At the same time, the CPU 54 sets a keyword processing flag. The value of this flag is stored in memory 56. The method of extracting keywords is not particularly limited. For example, the order stored in the keyword storage unit 62 may be used. Keywords may be randomly extracted. When keywords are stored in the keyword storage unit 62 in the order of priority, the keywords may be extracted in the order of priority. In the case of the present embodiment, since the priority (for example, “+1” or “+3”) is set for each keyword, the CPU 54 derives the keywords in descending order of the priority.

In S 124, CPU 54 determines whether or not metadata including a keyword exists. If it is determined that the metadata including the keyword exists (YES in S124), the process proceeds to S126. If not (NO in S124), the process proceeds to S120. In S 126, CPU 54 stores the sub data including the metadata (containing the keyword) in memory 56. Thus, it is determined that the displayed sub data is the sub data stored in the memory 56.

In S128, CPU 54 determines whether or not a character string that matches the character string included in the metadata exists in the character string included in the display data. If it is determined that a character string exists (YES in S128), the process proceeds to S130. If not (NO in S128), the process proceeds to S132.

In S 130, CPU 54 lowers the priority of character data stored in character string storage 66 and representing a character string that matches the character string included in the metadata by “1”. As a result, the CPU 54 determines the relative priorities of the plurality of character data. In S132, CPU 54 resets the processing flag of the keyword.

In S134, CPU 54 determines whether an unprocessed keyword exists in the keywords included in either the display data or the sub data. If it is determined that an unprocessed keyword exists (YES in S134), the process proceeds to S136. If not (N in S134), the process proceeds to S142.

In S136, CPU 54 extracts a keyword from keyword storage section 62. Key The method of extracting the code is the same as in S122.

[0059] In S138, CPU 54 determines whether or not the display data includes the keyword extracted in S136. If it is determined that the display data includes the keyword (YES in S138), the process proceeds to S140. If not (NO in S138), the process proceeds to S134.

In S140, CPU 54 increases the priority of the character data stored in character string storage 66 that matches the keyword extracted in S136 by “0.5”. As a result, the CPU 54 determines the relative priority of the plurality of character data so that the priority of the character data representing the same keyword as the keyword stored in the keyword storage unit 62 becomes higher. .

Referring to FIG. 4, a program executed by data display device 50 has the following control structure for displaying display data.

In S 142, CPU 54 determines whether or not the type of the character string represented by the character data stored in character string storage section 66 can be determined. If it is determined that it can be determined (YE

S), the process proceeds to S144. If not (NO in S142), the process proceeds to S146.

In S 144, CPU 54 determines the type of the character string represented by the character data stored in character string storage 66. Information indicating the type of the character string determined by the CPU 54 is stored in the character string storage unit 66.

At S 146, CPU 54 determines whether the display data is a predetermined character string based on whether or not any of the character strings included in the display data matches the character string stored in genre table 64. Judge whether it belongs to any of the rules. As a result, the CPU 54 identifies the genre to which the display data belongs. If it is determined that the data belongs to the predetermined difference or the deviation (YES in S146), the process proceeds to S148. If not (NO in S146), the process proceeds to S152.

In S148, CPU 54 determines whether or not the display data includes a character string stored in genre table 64 and increasing the priority. If it is determined that the character string is included (YES in S148), the process proceeds to S150. If not (NO in S148), the process proceeds to S152. In S150, the CPU 54 sets the priority stored in the character string storage 66. Among the values indicating the degree, the value of the character string matched in S148 is increased by “1”. As a result, the CPU 54 determines the relative priority of a plurality of character data depending on whether or not the character is determined based on the genre.

In S152, CPU 54 determines whether an unprocessed character string exists in the character string represented by the character data stored in character string storage 66. If it is determined that an unprocessed character string exists (YES in S152), the process proceeds to S154. If not (NO in S152), the process proceeds to S168. In S154, CPU 54 extracts an unprocessed character string. The extraction method is the same as in S122.

In S 156, CPU 54 determines whether there is any other unprocessed data in the character string represented by the character data stored in character string storage 66. If it is determined that other data exists (YES in S156), the process proceeds to S158. If not (NO in S156), the process proceeds to S164. In S158, CPU 54 extracts other data determined to exist in S156. The extraction method is the same as in S122.

[0068] In S160, CPU 54 determines whether or not another character string common to the character string represented by the character data stored in character string storage section 66 exists in the character string included in the display data. to decide. If it is determined that another character string exists (YES in S160), the process proceeds to S162. If not (NO in S160), the process proceeds to S156. In S162, the CPU 54 lowers the priority of the character data determined to be common in S160 by “1” among the priorities stored in the character string storage unit 66. Accordingly, the CPU 54 sets the relative priority of a plurality of character data items such that the priority of character data representing a common character is lower than the priority of character data representing a character different from the common character. The priority is determined according to the common characters.

[0069] In S164, CPU 54 determines whether or not to set the priority according to the type of the character string. If it is determined that the priority is to be set (YES in S164), the process proceeds to S166. If not (N in S164), the process proceeds to S152. In S166, CPU 54 extracts one piece of character data stored in character string storage section 66. When the character data is extracted, the CPU 54 specifies the type of the character string to which the extracted character data belongs. When the type of the character string is specified, the CPU 54 determines the priority of the character string by a predetermined setting information. Change according to the information. In the case of the present embodiment, when the type of the character string belongs to “time”, the priority is reduced by “2”. As a result, the CPU 54 determines the relative priorities of the plurality of character data.

Referring to FIG. 5, a program executed by data display device 50 has the following control structure for displaying display data.

In S168, CPU 54 determines whether the sub data can be displayed and whether the sub data to be displayed has not been determined. If it is determined that the sub data can be displayed and that the displayed sub data has not been determined (YES in S168), the process proceeds to S170. If not (NO in S168), the process proceeds to S180.

[0072] In S170, CPU 54 determines the sub data to be displayed. The determination method is not particularly limited. The display method may be, for example, a method through the same processing as S120-S126. The determination method may be a method in which sub-data is randomly extracted. The determination method may extract sub-data including metadata. The extraction method may be a method of extracting sub-data including a character string included in the metadata display data. In the present embodiment, the CPU 54 selects one of these methods based on the contents such as display data.

In S172, CPU 54 determines whether or not the displayed sub data includes metadata. If it is determined that metadata is included (YES in S172), the process proceeds to S174. If not (NO in S172), the process proceeds to S180.

In S174, CPU 54 determines whether or not to set the priority based on the metadata.

If it is determined that the priority is to be set (YES in S174), the process proceeds to S176. If not (NO in S174), the process proceeds to S180.

At S 176, CPU 54 determines whether or not a character string that matches the character string included in the metadata exists in the character string included in the display data (that is, character data representing the character string). I do. If it is determined that a character string exists (YES in S176), the process proceeds to S178. If not (NO at S176), the process proceeds to S180. In S178, the CPU 54 lowers the priority of the character data determined to match in S176 by “1”. This allows the CPU 54 to determine the relative priorities of a plurality of character data. It becomes.

Referring to FIG. 6, the program executed by data display device 50 has the following control structure for displaying display data.

In S180, CPU 54 determines whether or not the number N of characters of the display data exceeds the maximum number L of characters that can be displayed. If it is determined that it exceeds (YES in S180), the process proceeds to S182. If not (NO in S180), the process proceeds to S196. At S182, CPU 54 substitutes “0” for variable I.

In S 184, CPU 54 determines whether or not the difference S between the maximum number L of characters that can be displayed and variable I is greater than “0” (whether or not there is still a display space left). If it is determined that the value is larger than “0” (YES in S184), the process proceeds to S186. If not (NO in S184), the process proceeds to S196.

In S 186, CPU 54 determines whether or not character data with a high priority exists in character string storage 66 (whether or not the priorities stored in character string storage 66 are not all the same value). Is determined. If it is determined that character data with high priority exists (YES in S186), the process proceeds to S188. If not (NO in S186), the process proceeds to S192.

In S 188, CPU 54 extracts a character string having the highest priority among character strings represented by character data stored in character string storage section 66. In S190, CPU 54 adds the length (the number of characters) of the character data extracted in S188 to variable I.

In S 192, CPU 54 extracts character data whose storage position in character string storage 66 is near the beginning of the character data stored in character string storage 66 and not yet extracted. In this case, the CPU 54 extracts character data so that the number of characters matches the difference between the maximum number L of characters that can be displayed and the variable I. At S194, CPU 54 substitutes the maximum number L of characters that can be displayed into variable I. In S196, display unit 70 displays the character data extracted by CPU 54 in the order of appearance.

The operation of the data display device 50 based on the above structure and flowchart will be described.

[0083] [When Displaying Image Data Collection with Title] The CPU 54 sets the priority (S100). When the priority is set, the CPU 54 stores the display data received by the input unit 52 in the display data storage unit 60 (S102). In this case, the display data received by the input unit 52 is an image collection including a plurality of images (images of birds and flowers inhabiting Mt. Fuji) and information describing the entire image collection (the image collection). Title, etc.) in the form of a character string. The display data includes a display data body and sub data. The sub data includes the sub data body and metadata (in the case of this display data, information describing the sub data). In this case, the display data body is a character string that describes the entire image collection “Mt. Fuji Bird and Flower Image Collection”. One of the sub data is image data of Mt. Fuji. The metadata contained in this sub-data is a character string "Mt. Fuji". When the display data is stored, the CPU 54 determines whether there is a display instruction from the user or the system (S104). If there is a display instruction (YES in S104), CPU 54 determines the maximum number of characters that display unit 70 can display based on the area of the title display area and the size of the title characters accepted by input unit 52. L is determined (S106). When there are a plurality of display data, each of the display data is processed similarly. However, in this case, the display data is only the data described above.

When the number of characters is determined, the CPU 54 determines whether or not the number N of characters in the title portion of the display data exceeds the maximum number L of characters that can be displayed (S108). In this case, since it is determined that the number N of characters to be displayed exceeds the number L of characters that can be displayed (YES in S108), the CPU 54 decomposes the character string of the above-described title in the display data. As a result, the aforementioned tightle is decomposed into “Mt. Fuji”, “birds”, “flowers”, and “image collection”. When the character string is decomposed, the CPU 54 determines whether or not the display data is automatically collected data (S112). In this case, since the display data is not such data (NO in S112), CPU 54 determines whether or not the type of the character string represented by the character data stored in character string storage 66 can be determined. (S142). In this case, since the type of the character string cannot be determined (NO in S142), CPU 54 determines whether or not the display data belongs to any of the predetermined genres (S146). In this case as well, the display data does not belong to the predetermined difference or deviation (NO in S146), so the CPU 54 determines the character represented by all the character data stored in the character string storage 66. It is determined whether an unprocessed character string exists in the column (S152). In this case, since no character string has been processed yet (YES in SI 52), the CPU 54 extracts the character string. The character string is extracted from the character string stored in the character string storage unit 66 in the order of the character data. In the case of the title “Mt. Fuji Bird and Flower Image Collection”, the character string is extracted in the order of “Mt. Fuji”, “bird and flower”, “flower”, and “image collection”. In this case, “Mt. Fuji” is first extracted. When the character string is extracted, the CPU 54 determines whether or not other unprocessed data exists (S156). In this case, since all the other character strings represented by the character data stored in the character string storage unit 66 are not yet processed (YES in S156), the CPU 54 stores the other character strings from the character string storage unit 66. It is extracted (S158). In this case, the character string "bird" is extracted. When the character string is extracted, the CPU 54 determines whether or not the character string is common (S160). In this case, since the character strings are not common (N in S160), the processing of S156-S160 is repeated. Finally, the CPU 54 determines that there is no other unprocessed data in the character string storage unit 66 (NO in S156), so the CPU 54 determines whether or not to set the priority according to the type of the character string. Is determined (S164). In this case, since it is determined that the priority is not set depending on the type (NO in S164), the CPU 54 determines whether or not an unprocessed character string exists in the character string storage unit 66 (S152). . In this case, since all character strings have been processed (NO in S152), CPU 54 determines whether sub-data can be displayed and sub-data to be displayed has not been determined. (S168). In this case, since the sub data can be displayed and the sub data to be displayed has not yet been determined (YES in S168), CPU 54 determines the sub data to be displayed (S170). In this case, the CPU 54 determines to display the sub data including the metadata. When the sub data to be displayed is determined, the CPU 54 determines whether or not the sub data to be displayed includes metadata (S172). In this case, since the metadata is included (YES in S172), the CPU 54 determines whether or not to set the priority based on the metadata (S174). In this case, since the priority is set by the metadata (YES in S174), the CPU 54 matches the character string in the metadata in the character string of the title portion in the display data. It is determined whether or not the character string "Mt. Fuji" is included (S176). In this case, since the character IJ "Mt. Fuji" matching the metadata is included (YES in S176), the CPU 54 lowers the priority of the character "Mt. Fuji" by "1" (S178). When the priority is lowered, CP U54 determines whether or not the number N of characters in the title portion of the display data exceeds the maximum number L of characters displayed by the display unit 70 (S180). In this case, since the number N of characters in the title portion exceeds the maximum number L of characters that can be displayed (YES in S180), CPU 54 substitutes “0” for variable I (S182). When the value is substituted, the CPU 54 determines whether or not the difference between the maximum number L of characters that can be displayed on the display unit 70 and the variable I exceeds “0”. In this case, since it is determined that the value exceeds “0” (YES in S184), CPU 54 determines whether or not character data with high priority exists (S186). In this case, the priorities are all the same value “0” except for the character string “Mt. Fuji” (YES in S186). The character strings “birds” are extracted in order from (S188). When the character data is extracted, the CPU 54 adds the number of characters of the character data extracted in S188 to the variable I (S190). After the number of characters is added, the CPU 54 again determines whether or not the difference between the maximum number L of characters that can be displayed by the display unit 70 and the variable I exceeds “0” through the processing of S184 to S190 ( S 184). Ultimately, the value is less than “0” (NO in S184), so that display unit 70 displays the extracted character string (S196). In this case, all of the titles "Mount Fuji's Bird and Flower Image Collection" have the same value (0) except for the case where the priority of the character string "Mt. Fuji" is "-1". Assuming that the maximum number L of characters that can be displayed on the display unit 70 is 7, since the total number of characters of “with birds”, “of flowers”, and “image collection” is 7, the display unit 70 displays “with birds”. The character string "Flower Image Collection" will be displayed. In this case, "... an image collection of birds and flowers" is displayed to indicate that there is a character string that is not displayed. Through the processing of S180—S196, the CPU 54 determines the character data to be displayed based on the priority and the size of the area for displaying the character data (or the number of characters that can be displayed simultaneously with the priority). It becomes. Further, the CPU 54 displays the character data determined by itself and at least a part of the display data.

[When displaying the electronic schedule book]

The CPU 54 stores the display data representing the electronic schedule book accepted by the input unit 52 in the display data storage unit 60 (S102). The input unit 52 is used for inputting display data including the registered schedule from the interface and inputting the maximum size (for one day) capable of displaying the display data from the keyboard. Accept input. The contents of the display data stored in the display data storage unit 60 will be described with reference to FIGS. The The display data is stored in the display data storage unit 60 as two types of data tables. Figure 7 shows the contents of the first data table. The first data table is a data table indicating a relationship between a schedule registered by a user and an ID (Identification). Figure 8 shows the contents of the second data table. The second data table is a data table indicating the ID and the date and time of the schedule registered by the user. The CPU 54 converts the display data received by the input unit 52 into two types of data tables in advance, and stores those data tables in the display data storage unit 60. In this case, the display data input from the keyboard is “1st meeting”, “12:00 meeting”, and “3rd meeting”, “12:00 meeting”. And "15:00 meeting". In this case, the CPU 54 causes the display unit 70 to display the input display data. 9 and 10 show the contents of the image displayed on the display unit 70 at this time. FIG. 9 is a diagram showing the contents of the display unit 70 when the display data list S is displayed. FIG. 10 is a diagram showing the contents of display unit 70 when display data is displayed in a calendar. As shown in FIG. 9, in the case of the list display, all the display data input by the user are displayed. However, as shown in FIG. 10, when the display data is displayed by the calendar display, it becomes impossible to display all the contents of the display data. The reason is that the area for displaying the schedule for one day on the display unit 70 is too small. When the display data is stored, the CPU 54 determines whether there is a display instruction from the user or the system (S104). If there is a “display instruction” and the half-IJ is cut off (YES in S104), CPU 54 determines the maximum number L of characters that can be displayed in one-day area of display unit 70 (S106). In this case, the maximum number of characters L is determined to be 10 characters. When the maximum number L of characters is determined, the CPU 54 determines whether the number N of characters of the display data exceeds the maximum number L of characters that can be displayed (S108). In this case, in any of the display data, the number of characters N exceeds the maximum number of characters L (YES in S108), and thus the CPU 54 decomposes the character string data into clauses (S110). In this case, the display data “9:00 meeting” is decomposed into “9:00” and “meeting”. The display data “12:00 meeting” is decomposed into “12:00” and “meeting”. The display data “15:00 meeting” is decomposed into “15:00” and “meeting”. The character data obtained by the decomposition is stored in the character string storage unit 66. When character data is stored, S 1 12 Thereafter, the CPU 54 determines whether or not the type can be determined for each of the character data stored in the character string storage 66 (S142). In this case, it is determined that the type can be determined for “9:00”, “12:00”, and “15:00” (（£ 3 at 3142). 1:54 determines the type of these character strings as "time" (S144). When the type of the character string is determined, the CPU 54 determines whether or not there is an unprocessed character string through the processing of S146 (S152). In this case, since none of the character strings represented by the character data stored in the character string storage unit 66 has been processed (YES in S152), the CPU 54 extracts the character string “9:00” (S154). When the character string is extracted, the CPU 54 determines whether or not there is another unprocessed data (S156). In this case, since other data exists (YES in S156), CPU 54 extracts another character string “meeting” (S158). When another character string is extracted, the CPU 54 determines whether a common character string exists in the extracted character strings (S160). In this case, since there is no common character string (N in S160), the processing of S156 and S160 is repeated, and the character strings "12:00" and "meeting" are extracted. When these character strings are extracted, the CPU 54 determines again whether a common character string exists (S160). In this case, since a common character string “meeting” exists (YES in S160), the CPU 54 lowers the priority of the character string “meeting” by “1” (S162). When the priority is lowered, the processing of S156-S162 is repeated, and the priority of the character string "meeting" is lowered by "-4". Initially, the priority is “0” for any character string, so the priority of the character string “meeting” is “-4”. Thus, the CPU 54 determines the priority such that the amount of character data representing the common character corresponds to the low priority.

After the lowering of the priority, the CPU 54 again determines whether or not there is another unprocessed data (S156). In this case, since there is no other unprocessed data (NO at S156), the CPU 54 determines whether or not to set the priority according to the type (S164). In this case, since the priority is not set (NO in S164), the CPU 54 determines whether or not the subdata can be displayed and the subdata to be displayed has not been determined through the processing in S152. (S168). In this case, since the sub data cannot be displayed (N〇 in S168), the CPU 54 determines whether or not the number N of characters of each display data exceeds the maximum number L of characters that can be displayed in the one-day area of the display unit 72. Yes (S180). In this case, any display data Since the number N of characters of the display data exceeds the maximum number L of characters that can be displayed (YES in S180), the CPU 54 substitutes “0” for the variable I (S182). When “0” is substituted, the CPU 54 determines whether or not the difference between the maximum number L of characters that can be displayed and the variable I exceeds “0” (S184). In this case, since the difference exceeds “0” (YES in S184), CPU 54 determines whether or not character data with high priority exists (S186). In this case, since the priority of any character data is “0” (YES in S186), except that the priority of character data representing the character string “meeting” is “1 4” (YES in S186), the CPU 54 “9:00”, “12:00”, and “15:00” are extracted (S188). When the character data is extracted, the CPU 54 adds the number N of characters of the extracted character data to the variable I (S190). Since the total number of characters of the character strings “12:00” and “15:00” of “Day 3” is exactly 10, the CPU 54 determines that the difference between the maximum number L of characters that can be displayed and the variable I is equal to “0”. Judge (NO in S184). Since it is determined that the difference is equal to "0", the display unit 70 displays the character strings "12:00" and "15:00" in the "3rd day" column (3196). FIG. 11 is a diagram showing the display contents of the display unit 70 in this case. As is clear from this figure, the data display device 50 according to the present embodiment decomposes a certain character string A into short phrases such as Al, A2,..., And AN. When the character string is decomposed into phrases, the data display device 50 sets a priority for each phrase. When the priorities are set, the data display device 50 displays the phrases in the order of increasing the priority from the clauses of Al, A2, Select a clause. In this case, the character string "meeting" is not displayed. However, the character string displayed on the display unit 70 is originally scheduled to be registered by the user. Since the displayed character string is scheduled to be registered by the user, the user can easily guess that the displayed character string represents the schedule.

[When displaying the program list (1)]

The CPU 54 stores the display data representing the program list received by the input unit 52 in the display data storage unit 60 (S102). When the display data is stored, the CPU 54 decomposes the character string data for each phrase through the processing of S104 and S108 (S110). In this case, the display data is broken down into the program name, day, time, and channel. The decomposed character data is stored in the character string storage unit 66. When character data is stored, After processing, the CPU 54 determines whether or not there is an unprocessed character string (SI 52). In this case, since none of the character strings represented by the character data stored in the character string storage unit 66 has been processed (YES in S152), the CPU 54 extracts a character string representing the program name (S154). When the character string is extracted, the CPU 54 determines whether or not there is another unprocessed data (S156). In this case, since other data exists (YES in S156), CPU 54 again extracts a character string representing the program name (S158). When the display data is a program list, information on a plurality of programs is included, so that a plurality of pieces of information indicating program names may be included. This is the same for any day, time, and channel. When the character string representing the program name is extracted, the CPU 54 determines whether a common character string exists in the extracted character strings (S160). In this case, since there is a common character string (program name) (YES in S160), CPU 54 lowers the priority of the character string representing the program name by "1" (S162). When the priority is lowered, the processing of S156 and S162 is repeated, and the priority of the character string representing the program name is gradually lowered. Further, after the processing of S156-S162 is repeated and the priority of the character string representing the day of the week, time, and channel is also lowered, the CPU 54 again determines whether or not there is any other unprocessed data (S156). ).

[When displaying the program list (part 2)]

The CPU 54 stores the display data representing the program list received by the input unit 52 in the display data storage unit 60 (S102). In this case, the input display data represents a program list of the recorded television programs. With reference to FIG. 12, the contents of the display data stored in the display data storage unit 60 will be described. The display data includes the broadcast date and time, the broadcast time, a title such as “Thursday drama“ XXXXXXXXXXXX ”episode 1,” a keyword representing Giannore, the names and contents of the performers, and the G code. When the display data is stored, the CPU 54 causes the display unit 70 to display the title portion of the input display data. FIG. 13 shows an image displayed on the display unit 70 at this time. The display space for one display data is small. The display space is too small to display the title. After S104-S108, the CPU 54 decomposes the character string data into clauses (S110). In this case, the character string of the title in the display data is decomposed into “Thursday”, “Drama”, “XXXXXXXXXXXX”, and “Episode 1”. Override of these clauses The degrees are each "0". When the character string data is decomposed, through S112-S142, the CPU 54 determines whether the display data belongs to any one of the predetermined genres (S146). In this case, since the display data belongs to the “drama” of the predetermined genre (YES at S 146), CPU 54 includes the character string stored in genre table 64 to increase the priority. It is determined whether or not (S148). FIG. 14 shows character strings stored in the genre table 64 for increasing the priority. In the case of the present embodiment, the genres stored in the Jianno table 64 are “drama”, “series”, and “sports”. The character string that raises the priority for Jannore “Drama” is “Episode X”. The same applies to Giannore Series. In the case of Giannore “sports”, the character string that raises the priority is “team name vs team name”. In this case, the display data, Runode contains the string "Episode 1" (YES in S148), CPU54 is, the priority of the character string "Episode 1" raise "1" (S150) _o This Thus, the priority of the character string "Episode 1" is "+1". When the priority is increased by "1", the display unit 70 displays the character IJ through the processing of S152-S190 (S196). The contents displayed on the display unit 70 at this time will be described with reference to FIG. The “first episode” having the highest priority and the “Thursday drama” stored first in the character string storage section 66 are displayed. Note that an abbreviation symbol such as “····” may be displayed between “Thursday drama” and “first episode”. However, in the case of the present embodiment, the display unit 70 does not display such a symbol.

[When displaying the program list (part 3)]

The CPU 54 stores the display data received by the input unit 52 in the display data storage unit 60 (S102). In this case, it is assumed that the display data received by the input unit 52 is the same data as the data representing the program list in the above-described “when displaying the program list (No. 2)”. When the display data is stored, the CPU 54 determines whether or not the type of the decomposed character string can be determined through the processes of S104 and S112 (S142). In this case, since it is determined that the type of the character string can be determined (YES in S142), CPU 54 determines the type of the character string of the decomposed character data (S144). As a result, the classification power S “time” of the character strings “9:00” and “10:08” is determined. When the type of the character string is determined, the CPU 54 determines whether or not to set the priority according to the type of the character string through the processing of S146 and S162 ( S164). In this case, since it is determined that the priority is set according to the type of the character string (YES in S164), the CPU 54 changes the priority of the character data according to the type of the character string (S166). In this case, the priority for each character data is changed based on the value stored in the keyword storage unit 62. In the case of the character string type “Tokii”, the value stored in the keyword storage unit 62 is “1-1”. As a result, the priorities of the character strings "9:00" and "10:08" are each "-1". When the priority is changed, the display unit 70 displays a character string through the processing of S152-S190 (S196). FIG. 16 shows the contents displayed on the display unit 70 at this time. In this case, the time is not displayed. Since the time is not displayed, other information can be displayed.

[When displaying recommended information]

The CPU 54 stores the display data received by the input unit 52 in the display data storage unit 60 (S102). FIG. 17 shows the contents of the display data stored in the display data storage unit 60 at this time. In this case, the display data received by the input unit 52 is “recommended” information (not including sub data) automatically collected by the system. At the same time, the CPU 54 stores the keyword received by the keyboard of the input unit 52 in the keyword storage unit 62. In this case, it is assumed that the character strings “bargain” and “gourmet” have been input. FIG. 18 is a diagram showing the contents of keyword storage section 62 at this time. When the data is stored, the CPU 54 determines whether the display data received by the input unit 52 is a “recommended” display through the processing of S104-S110 (S112). In this case, since the display data is "recommended" (YES in S112), the CPU 54 determines whether or not the keyword storage unit 62 stores a registered keyword (S114). In this case, as indicated by the underline in FIG. 17, since the registered keyword is stored (YES in S114), CPU 54 determines whether or not display unit 70 can display the sub data (S116). . In this case, since the sub data cannot be displayed (NO in S116), the display unit 70 displays the display data through the processing of SI 34-1 S190. With reference to FIG. 19, the contents of the information displayed on display unit 70 at this time will be described. Of the display data, character strings such as “bargain” and “gourmet” stored in the keyword storage 62 are displayed. By the way, if the user inputs a bargain on a certain day to indicate a schedule, the schedule is displayed with priority. [To display recommended program data (with image sub-data)]

The input unit 52 receives display data and a user's favorite keyword (such as a user's favorite talent name). When the display data is received, the CPU 54 stores the display data received by the input unit 52 in the display data storage unit 60 (S102). With reference to FIG. 20, the configuration of data stored in display data storage unit 60 will be described. Each display data is assigned an ID number. The display data includes a display data body and sub data. The display data body includes information indicating the broadcast date and time, broadcast day, broadcast time zone, title, genre, performer, content, and G code. The sub data includes data representing an image of a scene in the program data, and metadata. Metadata is a type of character string data representing information of one-scene image data. The contents represented by the metadata include the display time of the scene to be represented by the metadata, the cast, the telop, the names of the subjects appearing in the scene, and the description of the scene. When the display data is stored in the display data storage unit 60, the CPU 54 determines whether the display data received by the input unit 52 is a recommended program through the processing of S104 to S110 (S112). In this case, since the display data is a recommended program (YES in S112), the CPU 54 determines whether or not the keyword storage unit 62 stores a registered keyword (S114). In this case, since the registered keyword is stored (YES in S114), CPU 54 determines whether or not display unit 70 can display the sub data (S116). In this case, since the sub data can be displayed (YES in S116), through S118, the CPU 54 determines whether there is an unprocessed keyword among the keywords included in either the display data or the sub data. A judgment is made (S120). In this case, since no keyword has been processed yet (YES in S120), CPU 54 extracts one of the unprocessed keywords (S122). When the keyword is extracted, the CPU 54 determines whether there is metadata including the keyword (S124). In this case, since there is metadata including the keyword (YES in S124), the CPU 54 stores the sub data including the metadata (containing the keyword) in the memory 56 (S126). As a result, if a program with the user's favorite talent (whose name is registered as a keyword in advance) is recorded as a recommended program, the talent is displayed from the sub-data image and metadata. Extract images The priority of the image can be raised. “Image priority” refers to the priority when determining which image has priority when the sub-data includes a plurality of images. When the sub data is stored in the memory 56, the CPU 54 determines whether or not a character string that matches the character string included in the metadata exists in the character string included in the display data (S128). When determining that the character string exists (YES in S128), the CPU 54 sets the priority of the character data representing the character string that matches the character string included in the metadata stored in the character string storage unit 66 to “ Lower by 1 ”(S130). That is, in the following cases, the CPU 54 determines the priority such that the priority of the latter character data is lower than the priority of character data different from the former and the latter character data. Become. In this case, the character data obtained by decomposing the metadata represents the same character as the character data obtained by decomposing the character string data included in the display data. When the priority is lowered, the CPU 54 resets the processing flag of the keyword (S132). When the flag is reset, the CPU 54 determines whether an unprocessed keyword exists in the keywords included in either the display data or the sub data (S134). In this case, since it is determined that there is no unprocessed keyword (NO in S134), through the processing of S142-S152, the CPU 54 can display the sub data, and the sub data to be displayed is It is determined whether or not it has been determined (S168). In this case, since the sub data can be displayed and the sub data to be displayed has not been determined yet (YES in S168), CPU 54 determines the sub data to be displayed (S 170). When the sub data is determined, the CPU 54 determines whether or not the sub data has metadata (S172). In this case, since it is determined that the metadata is included (YES in S172), CPU 54 determines whether or not to set the priority based on the metadata (S174). In this case, since it is determined that the priority is set by the metadata (YES in S174), the CPU 54 determines that the character string included in the display data body includes a character string that matches the character string included in the metadata. It is determined whether or not (S176). In this case, since it is determined that a character string that matches the character string included in the metadata is included (YES in S176), CPU 54 lowers the priority of the matching character data by "1" (S178). . When the priority is lowered, the display unit 70 displays the display data through the processing of S180-S190 (S196). The contents of the display unit 70 at this time will be described with reference to FIG. Display 7 In 0, an image of one scene of the drama, a character string indicating the episode, an image of the user's favorite talent, and information indicating the program name are displayed. Of the display data strings, the strings that match the metadata strings are given lower priority, so the names of the performers that are duplicated in the metadata strings are not displayed. Also, when the title, which is normally the title, is displayed, only the character string of “Episode 1” is displayed. XX 話 Χ Χ Χ Χ Χ Χ Χ Χ XX Since the user has reserved the program, the user can recognize the program data by looking at the images.

[0092] As described above, the data display device according to the present embodiment selects information to be displayed based on the priority. Since the information with the higher priority is displayed, the user can read the content from the lesser information accurately. In other words, when there is a large amount of text information, even when using a screen with a limited number of characters to be displayed, the user can easily and easily display the necessary information according to the various sizes of the text display area. it can. Further, when there are a plurality of data, the data display device according to the present embodiment selects information to be displayed so that common information is not displayed. Since common information is not displayed, it is easy to distinguish it from other data. In particular, when displaying the program list, the data display device according to the present embodiment lowers the priority of character strings having the same content such as the program name, day of the week, time, and channel. On the other hand, when a different subtitle exists every time in addition to the main title of the drama in the program name, the priority of the subtitle is relatively increased. When recording several episodes of a serial drama, it is difficult to identify individual data if the same program name, day of the week, time, and channel are arranged. As a result, the data display device according to the present embodiment allows the user to accurately read the contents of the program from a small amount of information.

[0093] Further, when displaying the recommended program, the data display device according to the present embodiment can understand the reason for recommendation only by looking at the image that is the sub data, and can display the display data from the character information displayed at the same time. Can understand the contents. Furthermore, the data display device according to the present embodiment lowers the priority of items (such as “Mt. Fuji” in the case of the above embodiment, which corresponds to power S) that can be grasped from the image. Since the priority is lowered, redundant information is not displayed, and a wide screen can be efficiently displayed on a small screen.

[0094] Further, the data display device according to the present embodiment can quickly and easily draw the user's interest. Information that is easy to understand can be displayed. Since such information is displayed, it becomes easy for the user to search for desired information. Further, the data display device according to the present embodiment can easily display the reason for recommendation when displaying recommended information.

[0095] Further, when displaying information representing a recorded drama, the data display device according to the present embodiment displays, together with an image representing a scene in a program, a character string not included in the metadata of the scene. indicate. When they are displayed, information can be displayed more quickly and efficiently even with a small number of displayed character strings. The reason that the information can be displayed more quickly and efficiently is that the user can recognize the program to some extent by looking at the image.

[0096] In the data display device according to the present embodiment, a character string for identifying a genre is stored in advance. As a result, even if the display data does not particularly include the information indicating the Jiannore, if the title or the like includes the character string for identifying the Jiannore, it is possible to identify the Jiannore.

[0097] Further, the data display device according to the present embodiment is configured such that the type of a character string included in each display data (in the present embodiment, "11/2" is a date, "(Thu)" is a day of the week, "9:00-10:08" is the time) and the priority is determined based on the type. For example, when display data such as “9:00 meeting, 12:00 lunch” is input in the electronic schedule book, the data display device according to the present embodiment uses “9:00:” and “12:00: It can be analyzed that "00" is the time. If the priority of the time is set in advance, "9:00" and "12:00" are displayed with priority. When the number of characters that can be further displayed is 10 characters, “9:00 12:00” is displayed on the display unit 70. This display method is easier to grasp that there are multiple schedules than the conventional display method “9:00 meeting”. If a program list is displayed and the priority of the time is set to be lower in advance, the data display device according to the present embodiment particularly displays the broadcast time even if the broadcast time of the serial drama changes. Instead of displaying the information, display information such as subtitles that help the user understand the contents of the program. In addition to lowering the priority of the character string common to the data, displaying the information in this way allows the user to more easily grasp the contents of the program.

[0098] Further, in the data display device according to the present embodiment, when a pre-registered keyword (such as "bargain" or "gourmet") is included in a character string, the keyword matches the keyword. The priority for character strings is "1" higher. As a result, keywords with higher priorities are displayed with priority. Since keywords are displayed with priority, the conventional method (displays only the number of characters that can be displayed in order from the front. “XX department store ...” is displayed on the display unit 70. Or, display all characters Compared to), it is easier to display that two pieces of recommended information are registered and that the information is about bargains and gourmet. If you want to know the details, you can look at all the data by changing the display mode. Since these are displayed in a simple and easy-to-understand manner, the existence of information, the contents of the information, and the reasons why it was collected can be understood to some extent. The reason why the information was collected can be understood, so that it is easy to determine whether to view the information in detail. It can also be applied to the display of information on recommended TV programs that can only be scheduled. The same applies to the display of ordinary program guides and ordinary display data that are not limited to recommended programs. This makes it easier for users to find their favorite programs when browsing the electronic program guide. This is because the registered keywords can be easily noticed.

[0099] As a result, a device that stores any of various contents such as a hard disk recorder, a DVD (Digital Versatile Disk) recorder, a video, a digital camera, a mobile terminal, and an electronic program guide, and displays information. When displaying a list of information, it is possible to display information in a manner that is more easily identified and easier for the user to guess, depending on the user's preference, based on the content stored individually. In other words, it is possible to provide a data display device that can easily display necessary information for a user even when the number of characters that can be displayed on the screen is limited when the amount of character information is large.

[0100] When the electronic schedule book is displayed, character data may be extracted in the processes of S184 to S190 until the number of displayed characters is equal to the maximum number L of characters. In this case, the character displayed in the “3rd day” column is “12:00 meeting 15:00 meeting”. As a result, character strings with high priority are displayed side by side as far as possible. Since the data is displayed side by side as much as possible, it is easy to distinguish data from each other and useful information can be displayed to the user.

[0101] In addition, a list of a plurality of programs is displayed, such as a series drama recorded several times. In this case, the priority of the image showing the performer who appears only in one episode (the sub-data that is easy to identify the contents of the display data among the sub-data of each display data) is raised. May be.

[0102] Further, when the display data includes an icon such as a G code, the icon may be regarded as sub-data. When displaying a list of program data, there may be a case where information indicating a user's operation that is not only displaying program information on the screen is also displayed. For example, the icon indicates a G code reservation when a reservation can be made using a G code, or an icon indicating a recording mode when there are a plurality of recording modes. Information indicating a user operation. There is no point in displaying such information if the user always selects the same operation or mode. Since it has no meaning, such information can be omitted. If that information is omitted, the maximum number of characters that can be displayed in the title can be increased. In other words, the priority of sub-data with low user usage and common contents is reduced. As a result, the display can be changed according to the user's usual operation, so that the display can be realized conveniently for the user.

[0103] In S110, CPU 54 may decompose the character string data by extracting the keyword stored in keyword storage section 62 from the character string data. In this case, the character string data is decomposed into character data having the same content as the keyword stored in the keyword storage unit 62 and a character string that does not match the keyword stored in the keyword storage unit 62 among the character string data. You.

[0104] In S196, when displaying the program list, CPU 54 selects display data based on the degree of coincidence between titles, the degree of coincidence between performers, the degree of coincidence between days of the week, and time of day. May be displayed.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive.
