Description

  The present invention relates to a document output control apparatus that provides an optimum summary sentence of an output target document in a display area for character information.

Conventionally, there are known automatic summarization systems and display systems that provide optimal complete sentences in the display area by calculating the number of characters from the display area that displays the document to be output and displaying a summary sentence according to the number of characters. ing.
For example, Patent Document 1 discloses a technique for outputting a document by decreasing the summary rate step by step when the document does not fit in the area defined by the output restriction condition.
For example, Patent Document 2 discloses a technique for calculating the resolution and the maximum number of characters from a display area in advance and adjusting the amount of characters to be displayed and the resolution when displaying related information on the Internet from accompanying data of video content. It is disclosed. Further, a technique for resummarizing an appropriate number of characters is newly disclosed when displaying a site where page editing is permitted.
Further, for example, Patent Document 3 discloses a method for dealing with a space limitation of a computing device that requires a page to convert a site on the Internet into a semantic thumbnail suitable for display on a different computing device.

For example, when displaying a TV program guide or detailed information of a program on the screen, in order to provide a document that is surely completed in the character information display area and understands the meaning, the document is summarized in accordance with the display area. There is a need.
On the other hand, the number of characters that can be displayed in the character information display area varies depending on the font of the displayed characters.
Therefore, in order to provide a complete and understandable document, when the font of the displayed character is changed, it is necessary to summarize the document in consideration of the changed font of the character.

However, with the technique disclosed in Patent Document 1, it is possible to reduce the document to be output so that it falls within the area defined by the output constraint conditions by adjusting the number of characters by gradually reducing the summarization rate. However, since the font of the characters is not taken into account, if the font of the characters displayed in the character information display area is changed, a summary that can be surely completed and understand the meaning is created. There was a problem that there might not be.
Further, Patent Document 1 has a problem that once summarized, the document cannot be summarized again.

On the other hand, in the technique disclosed in Patent Document 2, when displaying a site where page editing is permitted, it can be re-summarized again to an appropriate number of characters. The problem of not being able to summarize the document again can be solved.
However, since Patent Document 2 summarizes the amount of characters to be displayed based on the resolution of the display area and the maximum number of characters, not the font size of the document to be displayed, the characters that are still displayed in the character information display area There was a problem that when the font of was changed, there was a case where the summary could not be completed so that the sentence could be surely completed and understood.

  In addition, in the technique disclosed in Patent Document 3, it is disclosed that text is summarized according to a space restriction included in a computing device, but the technique disclosed in Patent Document 3 is simply The purpose is to summarize the document to maintain readability even on a small screen. Like Patent Documents 1 and 2, consideration is not given to the case where the font size of the displayed document is changed. There was a problem that there was no summary that could be understood.

  The present invention has been made to solve the above-mentioned problems, and the change of the font size and automatic document summarization are interlocked, and the document summarization according to the font size of the displayed document is performed reliably. An object of the present invention is to provide a document output control device that can output a summary sentence that is completely completed and can be understood.

  A document output control device according to the present invention includes a character amount determination unit that determines the number of characters of an output target document, and information regarding font size change, and a display character number determination that determines the number of characters that can be displayed in a display area of character information in a display unit Display character number comparison / determination unit that determines whether the summary of the output target document is necessary based on the number of characters of the output target document determined by the copy number, the character amount determination unit, and the number of characters determined by the display character number determination unit, and the number of display characters When the comparison / determination unit determines that the summary of the output target document is necessary, a summary unit that creates a summary sentence of the output target document and an output unit that displays the summary sentence created by the summary unit in a display area are provided. It is a thing.

  According to the document output control device of the present invention, the change of the font size and the automatic summarization of the document are linked, and the summarization of the document according to the font size of the displayed document is surely completed and the meaning can be understood. A summary sentence can be output.

Embodiment 1 FIG.

FIG. 1 is a configuration diagram of a document output control apparatus 100 according to Embodiment 1 of the present invention.
The document output control apparatus 100 according to the first embodiment, for example, receives information displayed in sentences, such as received program details, in a necessary amount and a required size in an arbitrary display area using a sentence summarization technique. It is a television etc. to be displayed on.

The document output control apparatus 100 includes an operation reception unit 11, a display area analysis unit 12, a display character number determination unit 13, a display character number comparison determination unit 14, a summarization unit 15, an output unit 16, a display unit 17, A character amount determination unit 18 and an output target document storage unit 19 are provided.
The operation reception unit 11 receives a change in the font size of characters from the operator. In addition, the operation reception unit 11 receives designation of an output target document from the operator. In the first embodiment, the output target document is, for example, a TV program guide, detailed program information, or the like.
The display area analysis unit 12 determines the size of the display area for character information in the content display area.

The display character number determination unit 13 displays the font received by the operation reception unit 11 in the display area of the character information determined by the display region analysis unit 12 when the operation reception unit 11 receives a change in the font size of the character from the operator. Determines how many characters of size can be displayed. When the operation reception unit 11 has not received a change in the font size of the character from the operator, the display character number determination unit 13 sets the font size of the character as a preset standard size in the initial state. The number of characters that can be displayed in the display area of the character information determined by is determined.
The display character number comparison / determination unit 14 determines whether the output target document needs to be summarized based on the number of characters determined by the display character number determination unit 13 and the information of the output target document determined by the character amount determination unit 18. When summarization is required, the summarization rate of the output target document is calculated.
The summarization unit 15 summarizes the output target document using the summarization ratio calculated by the display character number comparison / determination unit 14 when the display character number comparison / determination unit 14 determines that the output target document needs to be summarized. Create a statement.

When the display character number comparison / determination unit 14 determines that the output target document needs to be summarized, the output unit 16 causes the display unit 17 to display the summary sentence created by the summary unit 15. If the display character number comparison / determination unit 14 determines that it is not necessary to summarize the output target document, the output unit 16 directly uses the output target document acquired by the character amount determination unit 18 from the output target document storage unit 19. It is displayed on the display unit 17.
In response to an instruction from the output unit 16, the display unit 17 displays a summary sentence of the output target document or an output target document that is not summarized. In the first embodiment, as shown in FIG. 1, the display unit 17 is included in the document output control device 100, but the display unit 17 is not limited to this, and the display unit 17 is external to the document output control device 100. It is good also as what is prepared for.

The character amount determination unit 18 acquires and acquires an output target document to be presented to the operator from the output target document stored in the output target document storage unit 19 in accordance with the operation of the operator received by the operation reception unit 11. The amount of characters in the output target document is determined. In the first embodiment, the character amount refers to the number of characters.
The output target document storage unit 19 stores the output target document. In the first embodiment, as shown in FIG. 1, the output target document storage unit 19 is included in the document output control apparatus 100. However, the present invention is not limited to this, and the output target document storage unit 19 It may be provided outside the output control device 100.

The operation will be described.
FIG. 2 is a flowchart for explaining the operation of the document output control apparatus 100 according to Embodiment 1 of the present invention.
For example, when the viewer wants to confirm the details of the currently viewed program, the program table, or the list of recorded recorded programs on the currently viewed screen, a document for the confirmation is displayed on the screen. Display. The document for confirmation is, for example, information on the details of a program or a program guide, and the document is an output target document here. The document output control apparatus 100 outputs an output target document.
Hereinafter, the operation of the document output control apparatus 100 when, for example, outputting the output target document from the screen that the viewer is currently viewing will be described with reference to FIG.

  The display area analysis unit 12 analyzes the display area (step ST201). Specifically, first, the display area analysis unit 12 determines the size of the display area for character information in the content display area of the display unit 17. The display area analysis unit 12 outputs the display area size information of the character information determined in step ST201 to the display character number determination unit 13.

The amount of character information that can be provided to the operator varies depending on the size of the display area to be displayed.
Therefore, first, in step ST201, the display area analysis unit 12 displays a display area in which detailed information of the program being viewed and the output target document of the TV program guide can be displayed on the screen of the display unit 17 being viewed by the viewer. Judge the size.
Information about how large the content display area and the program detail display area are set by the viewer is stored in the document output control device 100, and the display area analysis unit 12 stores the stored information. From the setting information, the size of the display area where the output target document can be displayed is determined based on the information of the program detail display area.

  The operation receiving unit 11 waits until an output target document specification is received from the operator (in the case of “NO” in step ST202), and when the operation receiving unit 11 receives the output target document specification (“YES” in step ST202). ”), The character amount determination unit 18 outputs the output target document to be presented to the operator from the output target document stored in the output target document storage unit 19 in accordance with the operation of the operator received by the operation receiving unit 11. And the character amount of the acquired output target document is determined (step ST203). The character amount determination unit 18 outputs the determined character amount information to the display character number comparison determination unit 14.

  The output target document storage unit 19 stores program detail information in association with, for example, a program ID, and the character amount determination unit 18 is currently being viewed by the viewer, that is, displayed on the screen. The detailed program information associated with the program is acquired as an output target document, and the amount of characters included in the detailed program information of the program A is determined. Here, the amount of characters refers to the number of characters.

The operation reception unit 11 determines whether or not there has been a font size change instruction from the operator (step ST204).
In the first embodiment, the operator can change the font size of the characters of the output target document displayed on the screen. Specifically, for example, when it is difficult to see the characters on the TV because of poor vision, or when it is difficult to see the characters on the TV because of the distance to the TV, or there is not a specific program that you want to watch. For example, if you want to display a lot of information because you want to decide the program to watch after knowing in detail, the operator should, for example, press the font size change button on the remote control to increase or decrease the font Thus, an instruction is given to change the font size of the characters of the output target document to a desired font size.
In the first embodiment, it is assumed that a standard size is set and stored in advance as an initial state of the font size of characters.

When there is no instruction to change the font size (in the case of “NO” in step ST204), the display character number determination unit 13 sets the font size of the character as a standard size set in advance, and in the initial state, the display area analysis unit 12 in step ST201. The number of characters that can be displayed in the character information display area determined by is determined (step ST213). Then, the process proceeds to step ST206.
When there is a font size change instruction (in the case of “YES” in step ST204), the operation reception unit 11 outputs the changed font size information received from the operator to the display character number determination unit 13, and displays the number of display characters. The determination unit 13 receives the changed font size information output from the operation reception unit 11, and displays the character information display area determined by the display area analysis unit 12 in step ST201. The number of characters that can be displayed with the received changed font size is determined (step ST205).

FIG. 3 is a diagram for explaining the relationship between the font size in the character information display area and the number of displayable characters.
As shown in FIG. 3, even if the display area of the character information is the same size, the number of characters that can be displayed changes if the font of the displayed characters is different. Specifically, the larger the font of characters, the fewer the number of characters that can be displayed.
Therefore, in step ST205, the display character number determination unit 13 determines the number of characters that can be displayed based on the received font size change instruction. In this way, even when the viewer changes the font size in various ways according to the viewing situation, the number of characters that can be displayed with the specified font size can always be set, and based on the set number of characters In the subsequent processing, it is possible to display a complete sentence so that the display target document is not cut.

When the font size change instruction is received in step ST204, the display character number comparison / determination unit 14 determines the number of characters determined by the display character number determination unit 13 in step ST205 and the number of characters of the output target document determined by the character amount determination unit 18 in step ST203. Based on this information, the number of display characters is compared (step ST206), and it is determined whether the output target document needs to be summarized (step ST207).
If the font size change instruction is not accepted in step ST204, the display character number comparison / determination unit 14 determines the number of characters determined by the display character number determination unit 13 in step ST213 and the output determined by the character amount determination unit 18 in step ST203. Based on the information on the number of characters of the target document, the number of displayed characters is compared (step ST206), and it is determined whether the output target document needs to be summarized (step ST207).

Specifically, the display character number comparison / determination unit 14 determines the number of characters that can be displayed in the character information display area after the font size change determined by the display character number determination unit 13 (in the case of “YES” in step ST204), or the initial state. The number of characters that can be displayed in the character information display area (in the case of “NO” in step ST204) is compared with the number of characters of the output target document determined by the character amount determination unit 18, and the font determined by the display character number determination unit 13 is determined. If the number of characters that can be displayed in the character information display area after the size change or the number of characters that can be displayed in the character information display area in the initial state is larger, there is a display area sufficient to display the output target document. It is determined that the summary of the output target document is not necessary and can be displayed as the original text of the output target document. On the other hand, the display character number comparison / determination unit 14 compares the number of characters and determines the number of characters that can be displayed in the character information display region after the font size change determined by the display character number determination unit 13 or the character information display region in the initial state. If the number of characters that can be displayed is smaller, if the output target document is displayed as it is, the sentence will be cut off, and it is determined that summarization is necessary.
For example, when viewing the program details of the program A in the program details display area while viewing the content, the number of characters that can be displayed in the program details display area is the program details of the program A stored in the output target document storage unit 19. If it is greater than the number of characters, the display character number comparison / determination unit 14 determines that summarization is not necessary, and the number of characters that can be displayed in the program detail display area is smaller than the number of characters in the program details of program A stored in the output target document storage unit 19. For example, the display character number comparison / determination unit 14 determines that summarization is necessary.

When it is determined in step ST207 that summarization is necessary (in the case of “YES” in step ST207), the display character number comparison / determination unit 14 calculates the summarization rate of the output target document (step ST208). Specifically, the display character number comparison / determination unit 14 determines the number of characters that can be displayed in the character information display area after the font size change determined by the display character number determination unit 13, or the number of characters that can be displayed in the character information display area in the initial state. The summarization ratio is calculated based on the number of characters of the output target document determined by the character amount determination unit 18 and the difference between the two characters. The display character number comparison / determination unit 14 displays the output target document in the character information display area after the font size change determined by the display character number determination unit 13 or in the character information display area in the initial state. Any method for calculating the summarization rate can be used as long as it can calculate the summarization rate that can be expressed by the number of characters within the number of possible characters.
The display character number comparison / determination unit 14 outputs the calculated summary rate to the summary unit 15.

  The summary unit 15 creates a summary sentence that summarizes the output target document using the summary rate calculated by the display character number comparison / determination unit 14 in step ST208 (step ST209). Specifically, the summary unit 15 may summarize the output target document using, for example, an existing sentence summarization technique. The summary unit 15 outputs the created summary sentence to the output unit 16.

  The output unit 16 outputs the summary sentence of the output target document created by the summarization unit 15 in step ST209 to the display unit 17 for display (step ST210). The display unit 17 displays the summarized output target document in the character information display area. Note that the font size of the character displayed on the display unit 17 at this time is the font size after the change when there is a font size change instruction in step ST204.

  On the other hand, when it is determined in step ST207 that summarization is unnecessary (in the case of “NO” in step ST207), the processing in steps ST208 and 209 is skipped, and the display character number comparison / determination unit 14 determines the character amount determination unit 18 in step ST203. Outputs the output target document acquired from the output target document storage unit 19 to the output unit 16 as it is, and the output unit 16 outputs the output target document as it is to the display unit 17 for display (step ST210). Note that the font size of the character displayed on the display unit 17 at this time is the font size after the change when there is a font size change instruction in step ST204.

The operation receiving unit 11 determines whether an instruction to end display of the output target document has been received from the operator (step ST211). Specifically, for example, the operator performs an operation of selecting and clicking the program detail character display end button displayed on the screen from the remote controller, thereby instructing the display end of the output target document. Then, it is determined whether or not the operation is accepted.
If an instruction to end display of the output target document is received in step ST211 (in the case of “YES” in step ST211), the display processing of the output target document is ended. At this time, the operation reception unit 11 sets the font size of characters displayed in the character information display area to an initial value, that is, a preset standard size.
When the display processing of the output target document is finished, for example, the screen returns to the screen that the viewer was watching, or when the output target document is the program guide, for example, the viewer desires from the program guide. If the program is selected, the screen is changed depending on the situation, such as a transition to the viewing screen of the selected program.

In step ST211, when the display end instruction for the output target document is not received (in the case of “NO” in step ST211), the operation receiving unit 11 determines whether or not the font size change instruction is issued from the operator (step ST212). ). Since the specific operation is the same as that in step ST204, detailed description is omitted.
In step ST212, when there is no instruction to change the font size from the operator (in the case of “NO” in step ST212), the process returns to step ST211.

  In step ST212, when a font size change instruction is accepted from the operator (in the case of “YES” in step ST212), the process returns to step ST205 and the subsequent processing is repeated. As a result, even if the font size of the character is changed once and the summary text of the document to be output is displayed in accordance with the change, the font size is changed again, based on the received font size again. Then, the summary sentence of the output target document can be re-created, and the summary sentence that can be surely completed and understand the meaning can be output, always considering the font size of the characters.

  As described above, in the first embodiment, the operation receiving unit 11 receives an output operation of the output target document from the viewer, determines the character amount of the output target document (steps ST202 and 203), and then the viewer. If there is a font change instruction from, the display character number determination unit 13 receives the instruction and determines the number of characters to be displayed in the display area (steps ST204, 205, 213). Not exclusively. For example, if there is a font change instruction from the viewer, the display character number determination unit 13 receives the instruction, determines the number of characters to be displayed in the display area, and then the operation reception unit 11 outputs the output target document from the viewer. The operation may be accepted and the character amount of the output target document may be determined, or the operation of determining the character amount of the output target document and the operation of determining the number of characters to be displayed in the display area may be performed simultaneously. .

In the state, the number of characters that can be displayed in the display area of the character information determined by the display area analysis unit 12 is determined.
In the second embodiment, as shown in FIG. 5, the situation detection unit 20 is provided in the document output control apparatus 101. However, the situation detection unit 20 is not limited thereto, and the situation output unit 20 is not limited to this. You may make it prepare outside.

The operation will be described.
FIG. 6 is a flowchart for explaining the operation of the document output control apparatus 101 according to Embodiment 2 of the present invention.
The operations in steps ST701 to ST703 and steps ST707 to ST713 in FIG. 6 are the same as the operations in steps ST201 to ST203 and steps ST205 to ST211 in FIG. Is omitted.
Hereinafter, operations of Step ST704 to Step ST706 and Step ST714 to Step ST715, which are different from Embodiment 1, will be described in detail.

  Here, for example, the situation detection unit 20 is a distance detection sensor installed on the television, and the font of the character displayed in the character information display area is automatically changed according to the distance between the television and the viewer. An example of creating and displaying a summary sentence according to the font of the character changed in step 1 will be described below.

The situation detection unit 20 detects information related to the viewer or the situation around the viewer (step ST704). Specifically, here, the distance between the television and the viewer is detected.
The situation detection unit 20 outputs the detected information to the situation determination unit 21.

The situation determination unit 21 determines the viewing situation of the viewer based on the viewer or the information about the situation around the viewer detected by the situation detection unit 20 in step ST704 (step ST705), and the font size is changed. It is determined whether it is necessary (step ST706). If it is determined that the font size needs to be changed (“YES” in step ST706), status determination unit 21 outputs a change instruction to change the font size to display character number determination unit 13, and step ST707. Proceed to
If it is determined that it is not necessary to change the font size (in the case of “NO” in step ST706), the situation determination unit 21 outputs an instruction to the display character number determination unit 13 that it is not necessary to change the font size. The process proceeds to step ST717.

Specifically, here, for example, when the viewer is sitting on the sofa in front of the television, when the distance between the television and the viewer detected by the distance detection sensor that is the situation detection unit 20 is short, The determination unit 21 determines that the font size of the character displayed in the character information display area is the standard size that is an initial value, and that the font need not be changed ("NO" in step ST706).
In addition, for example, when the viewer is viewing the television from a location far from the television such as a kitchen or a dining room, when the distance between the television detected by the distance detection sensor that is the status detection unit 20 and the viewer is long, The determination unit 21 determines that the font size of the character displayed in the character information display area needs to be changed to a larger size, and outputs a change instruction to change the font size to a larger size to the display character number determination unit 13 ( “YES” in step ST706). At this time, the large font size set by the situation determination unit 21 can be set as appropriate. For example, the ratio of increasing the font size may be set in advance according to the distance between the television and the viewer.

  Also, whether or not the distance between the TV and the viewer is close may be set, for example, by setting a threshold in advance, and the situation determination unit 21 may be longer than the threshold if the distance between the TV and the viewer is shorter than the threshold. For example, the range of the distance between the television and the viewer is divided into several patterns, and the font size corresponding to the pattern is set in advance. The situation determination unit 21 may determine the font size corresponding to the distance between the television and the viewer based on the preset information.

  If it is determined that there is no need to change the font size (in the case of “NO” in step ST706), the situation determination unit 21 outputs an instruction to the display character number determination unit 13 that it is not necessary to change the font size. The display character number determination unit 13 determines the number of characters that can be displayed in the display area of the character information determined by the display region analysis unit 12 in step ST701 in the initial state with the font size of the character set as a standard size set in advance (step ST717). ). Then, the process proceeds to step ST708. The specific operation is the same as step ST213 in FIG.

When it is determined that the font size needs to be changed (in the case of “YES” in step ST706), the situation determination unit 21 outputs the determined change instruction to the changed font size to the display character number determination unit 13 for display. The number-of-characters determination unit 13 determines the number of characters that can be displayed with the font size determined by the status determination unit 21 in step ST706 in the character information display region determined by the display region analysis unit 12 in step ST701 (step ST707). The specific operation is the same as step ST206 in FIG.
In this way, the display character number determination unit 13 determines the situation around the viewer from the information detected by the situation detection unit 20 from the information detected by the situation detection unit 20 regardless of the operation of the font change instruction from the viewer. Information on an instruction to change the determined font size can be acquired to determine the number of characters that can be displayed in the character information display area.

If the display character number comparison / determination unit 14 determines in step ST706 that the font size needs to be changed, the number of characters determined by the display character number determination unit 13 in step ST707 and the output determined by the character amount determination unit 18 in step ST703. Based on the information on the number of characters in the target document, the number of displayed characters is compared (step ST708). If it is determined in step ST706 that there is no need to change the font size, the number of characters determined by the display character number determining unit 13 in step ST717 Based on the information on the number of characters of the output target document determined by the character amount determination unit 18 in step ST703, the display character number is compared and determined (step ST708). The specific operation is the same as step ST206 in FIG.
The subsequent operations in step ST709 to step ST713 are the same as the operations in step ST207 to step ST211 in FIG.
In step ST713, when an instruction to end display of the output target document is received (in the case of “YES” in step ST713), the process ends. At this time, the operation reception unit 11 sets the font size of characters displayed in the character information display area to an initial value, that is, a preset standard size.

In step ST713, when the display end instruction for the output target document is not received (in the case of “NO” in step ST713), the situation detection unit 20 detects information on the viewer or the situation around the viewer ( Step ST714). The specific operation is the same as in step ST704.
The situation determination unit 21 acquires information about the viewer or the situation around the viewer detected by the situation detection unit 20 in step ST714, and whether or not the previously acquired viewer or the situation around the viewer has changed. It is determined whether or not (step ST715). Specifically, the situation determination unit 21 stores information about the latest viewer acquired from the situation detection unit 20 or the situation around the viewer, and stores the latest viewing stored. By comparing the information about the situation around the viewer or the viewer with the information detected by the situation detection unit 20 at step ST714, it is determined whether the situation around the viewer or the viewer has changed. To do.
If it is determined in step ST715 that the viewer or the situation around the viewer has not changed (in the case of “NO” in step ST715), the process returns to step ST713.

When it is determined in step ST715 that the viewer or the situation around the viewer has changed (in the case of “YES” in step ST715), the situation determination unit 21 detects the viewer detected by the situation detection unit 20 in step ST714. Alternatively, the viewer's viewing status is determined based on the information about the status of the viewer's surroundings, and it is determined whether the font size needs to be changed (step ST716). The specific operation is the same as steps ST705 and 706.
If it is determined in step ST716 that it is not necessary to change the font size (in the case of “NO” in step ST716), the process returns to step ST713.

  If it is determined in step ST716 that the font size needs to be changed (in the case of “YES” in step ST716), the process returns to step ST707 and the subsequent processing is repeated. Thus, even if the viewer's viewing status changes after the font size of the character is changed once and the summary sentence of the output target document is displayed in accordance with the change, the acquired viewer or viewing A summary sentence of the document to be output is recreated according to information on the situation around the user, and a summary sentence that can be surely completed and understand the meaning is always output in consideration of the font size of the character and displayed on the display unit 17 Can be made. Specifically, for example, because the viewer was in the kitchen and was watching the television from a location far from the television, after creating and displaying a summary sentence of the output target document with a larger font size, If you have completed the errands and are now sitting on the sofa in front of the TV and watching the TV, the viewer has moved to the front of the TV, that is, the TV is close to the viewer. Accordingly, the font size can be changed to the standard size, and the summary sentence of the output target document can be created and displayed again with the standard size characters as necessary.

  As described above, in the second embodiment, the operation receiving unit 11 receives an output operation of the output target document from the viewer and determines the character amount of the output target document (steps ST702 and 703), and then detects the situation. When the situation determination unit 21 determines that the font size needs to be changed based on the information from the unit 20, the display character number determination unit 13 determines the number of characters to be displayed in the display area in response to an instruction from the situation determination unit 21. (Steps ST704 to 707, 716), but the order of this operation is not limited to this. For example, when the situation determination unit 21 determines that the font size needs to be changed based on information from the situation detection unit 20, the display character number determination unit 13 displays in the display area in response to an instruction from the situation determination unit 21. After the number of characters to be determined is determined, the operation receiving unit 11 may receive an output operation of the output target document from the viewer and determine the character amount of the output target document, or may determine the character amount of the output target document. The operation and the operation for determining the number of characters to be displayed in the display area may be performed simultaneously.

In the above description, for example, the situation detection unit 20 is a distance detection sensor installed on the television, the viewing situation of the viewer is determined according to the distance between the television and the viewer, and automatically when necessary. In the example described above, the font size of the characters displayed in the character information display area is changed, and a summary sentence is created and displayed according to the changed font size. Is not limited to the distance between viewers and viewers.
Hereinafter, another example of determining the viewing status of the viewer will be described.

For example, the situation detection unit 20 is a scroll speed detection sensor that detects the speed of the scroll operation from the remote controller provided in the television, and the viewing situation is determined based on the viewer's scrolling speed when scrolling the page. It may be determined and the font size of the character displayed in the character information display area may be changed.
Specifically, for example, based on the scroll speed information detected by the scroll speed detection sensor, the situation determination unit 21 greatly changes the font size when the scroll speed is greater than or equal to a preset threshold value. That is, when the viewer scrolls at a high speed, there is a high possibility that the displayed information is skipped, so the situation determination unit 21 changes the font size greatly. As a result, the number of characters that can be displayed in the character information display area is reduced, and the displayed output target document or the summary sentence of the output target document is also shortened. The viewer can grasp the contents of the output target document in a short time with a short sentence, and can reduce the troublesomeness of scrolling.

  On the other hand, for example, based on the scroll speed information detected by the scroll speed detection sensor, the situation determination unit 21 changes the font size to be smaller when the scroll speed is less than a preset threshold value. That is, when the viewer scrolls slowly, the font size is changed to be small because there is a high possibility that the displayed information is scrolled while reading over time. As a result, the number of characters that can be displayed in the character information display area increases, and the displayed output target document or the summary sentence of the output target document also becomes longer. The viewer can grasp a larger amount of information on one screen over the output target document over a slow time.

Further, if the scroll speed detected by the scroll speed detection sensor is within a preset range, the situation determination unit 21 sets the font size to the standard size that is the initial value, and the font size does not need to be changed. You may make it judge.
In this way, the font size of the characters displayed in the character information display area is set according to the scrolling speed of the viewer, and the font size is automatically changed at the same time as the scrolling speed changes. By determining the length, it is possible to provide the output target document so that it can be completely completed and the meaning can be understood according to the viewing situation of the viewer.

Further, for example, the situation detection unit 20 is a human sensor that detects a person's movement installed in a room with a television, and determines the viewing situation based on the movement of the viewer, and automatically displays a character information display area. You may make it change the font size of the character displayed on.
Specifically, the situation determination unit 21 determines the viewer's motion when the motion amount is equal to or greater than a preset threshold based on the information on the movement of the person detected by the human sensor, that is, the movement information of the viewer. If it can be determined that the movement is large or fast, the font size is greatly changed. In other words, if the viewer's movement is large or fast, there is a high possibility that the viewer is busy, so the font size is greatly changed. As a result, the number of characters that can be displayed in the character information display area is reduced, and the displayed output target document or the summary sentence of the output target document is also shortened. The viewer can grasp the contents of the output target document in a short time with a short sentence.

  On the contrary, the situation determination unit 21 reduces the font size when the amount of movement is less than a preset threshold based on the information on the movement of the person detected by the human sensor, that is, the movement information of the viewer. change. That is, when the viewer's movement is small or slow, there is a high possibility that the viewer is not busy, so the font size is changed to a small size. As a result, the number of characters that can be displayed in the character information display area increases, and the displayed output target document or the summary sentence of the output target document also becomes longer. The viewer can grasp a larger amount of information on one screen over the output target document over a slow time.

  In addition, if the amount of movement based on the information on the movement of the person detected by the human sensor is within a preset range, the situation determination unit 21 sets the font size to the standard size that is the initial value, and changes the font. May be determined to be unnecessary.

  As described above, the font size of the characters displayed in the character information display area can be set according to the life pattern of the viewer, that is, in the above-described example, the busy time zone of the viewer. In the above example, the life pattern of the viewer is determined based on, for example, the degree of busyness based on the information on the movement of the person detected by the human sensor, but this is merely an example, You may make it discriminate | determine by the method. For example, the time zone in which the father often watches TV or the time zone in which the grandmother often watches TV is registered in advance, and the situation determination unit 21 determines the life pattern from the registered information, and often In the time zone when watching TV, the font size of the character displayed in the character information display area can be changed to a font size corresponding to the time zone.

In addition, for example, the situation detection unit 20 is a face recognition sensor installed in a room with a television, and the viewing situation is determined based on the viewer's line of sight and facial expression, and the characters displayed automatically in the character information display area are displayed. The font size may be changed.
Specifically, the situation determination unit 21 greatly changes the font size when it can be determined that the viewer is narrowing his eyes based on information on the viewer's facial expression detected by the face recognition sensor. That is, when the viewer is narrowing his eyes, the viewer is likely to feel that characters on the screen are difficult to read, so the font size is greatly changed. As a result, the number of characters that can be displayed in the character information display area is reduced, and the displayed output target document or the summary sentence of the output target document is also shortened. For the viewer, it is possible to make the content of the output target document easier to see with short sentences of large characters.

  On the contrary, the situation determination unit 21 changes the font size to be smaller when it can be determined that the viewer is staring at the display area of the character information based on the viewer's line-of-sight information detected by the face recognition sensor. . That is, when the viewer is staring at one point, it is highly likely that the content of the output target document is being read interestingly, so the font size is changed to be small. As a result, the number of characters that can be displayed in the character information display area increases, and the displayed output target document or the summary sentence of the output target document also becomes longer. The viewer can grasp a larger amount of information on one screen over the output target document over a slow time.

In addition, when the situation determination unit 21 can determine from the viewer's face information detected by the face recognition sensor that the viewer who normally wears glasses or contacts has removed the glasses or contacts, the font size is determined. May be changed greatly. In other words, if the viewer who normally wears glasses or contacts removes the glasses or contacts, the viewer is likely to be in a situation where the characters on the screen are difficult to read, so the font size is greatly changed. This reduces the number of characters that can be displayed in the text information display area, shortens the displayed output target document or the summary text of the output target document, and allows the viewer to The contents of the document can be confirmed with short sentences with large letters.
Whether or not the viewer who normally wears glasses or contacts is in a situation where the glasses or contacts are removed can be determined by, for example, storing an image of wearing normal glasses in advance, No. 21 may be determined by matching the stored image with information on the face of the viewer detected by the face recognition sensor, or may be determined by other methods.

  In this way, the font size of characters displayed in the character information display area can be set in accordance with the line of sight and expression of the viewer.

For example, when the situation detection unit 20 is a face recognition sensor installed in a room with a television, the visual acuity of the viewer is determined based on the detected information on the face of the viewer, and the state detection unit 20 is automatically detected. You may make it change the font size of the character displayed on the display area of character information.
Specifically, when the situation determination unit 21 determines that the viewer has a healthy eyesight based on the information of the viewer's face detected by the face recognition sensor, the situation determination unit 21 uses the character size of the character information. However, since there is a high possibility that a larger amount of information is preferable, the font size is changed to be smaller. As a result, the number of characters that can be displayed in the character information display area is increased, the output target document to be displayed or the summary sentence of the output target document is lengthened, and the viewer can select the output target document or the output target document. You can get more information about the summary sentence on one screen.
Alternatively, when the situation determination unit 21 determines that the viewer is an elderly person or a viewer with poor vision based on the information of the viewer's face detected by the face recognition sensor, Since there is a high possibility that priority will be given to the size, the font size is changed greatly. This reduces the number of characters that can be displayed in the character information display area, shortens the displayed output target document or the summary sentence of the output target document, and makes it easier for viewers to use short sentences with large characters. The contents of the output target document can be grasped.

In this way, the font size of the characters for which character information is displayed is changed to one that corresponds to the visual acuity of the viewer, and the summary rate of the output target document that is output accordingly, and the length of the summary sentence You can make changes.
Note that the viewer's visual acuity is registered in advance, for example, by associating the viewer's face image with the visual acuity, and the situation determination unit 21 registers the information of the viewer's face detected by the face recognition sensor. What is necessary is just to make it identify by matching with the face image prepared previously, and the other method may be sufficient.

In addition, when it is determined that the viewer viewing the displayed output target document has been changed while the output target document is being displayed, the character of the character is changed simultaneously with the change based on the change of the viewer. You can also change the font size.
Specifically, for example, the situation determination unit 21 determines that the viewer has healthy vision based on the information on the viewer's face detected by the face recognition sensor, changes the font size to a smaller size, Assume that a long output target document or a summary sentence of the output target document is displayed.
Then, after that, based on the information on the viewer's face detected by the face recognition sensor, the situation determination unit 21 switches from a viewer with normal vision to, for example, an elderly person or a viewer with poor vision. When the determination is made, the font size is greatly changed to display a short output target document or a summary sentence of the output target document.
As described above, while viewing the output target document, the font size of the character displayed in the character information is appropriately changed according to the visual acuity of the viewer, and the output target document output accordingly is accordingly changed. It is possible to change the summary rate and the length of the summary sentence.

  Here, as an example, the situation determination unit 21 determines the change of the viewer based on the information of the viewer's face detected by the face recognition sensor. However, the present invention is not limited to this. For example, the situation detection unit 20 is a voice detection sensor, and the situation determination unit 21 acquires information about the voice of the viewer detected by the voice detection sensor, and determines the change of the viewer based on the voice information. Alternatively, the situation determination unit 21 may determine the change of the viewer based on information about the attributes of the viewer detected by the situation detection unit 20 such as face and voice information.

In addition, when the viewer viewing the displayed output target document is changed while the output target document is being displayed, the font size of the character is changed based on the change of the viewer, The length of the output target document to be displayed or the summary sentence of the output target document can be changed as described above. For example, when there are a plurality of viewers who simultaneously view the output target document, It is also possible to change the font size of the characters and change the length of the output target document to be displayed or the summary sentence of the output target document in accordance with the viewing situation by the viewer.
Specifically, for example, the situation detection unit 20 is a face recognition sensor, and the situation determination unit 21 is based on the face recognition information of a plurality of viewers detected by the face recognition sensor. If there are people with poor vision, the font size is greatly changed according to the elderly and people with poor vision.
On the other hand, based on the face recognition information of the plurality of viewers detected by the face recognition sensor, the situation determination unit 21 changes the font size to be small when the plurality of viewers are all persons with normal vision. .
Alternatively, a priority order that prioritizes the viewing situation is determined in advance for a plurality of viewers, and the situation determination unit 21 may change the font size based on the viewing situation of the viewer with the higher priority order. Good.
When there are a plurality of viewers who are simultaneously viewing the output target document displayed on the display unit 17, the situation determination unit 21 may change the font size according to the information regarding the attributes of the plurality of viewers. .

Further, for example, the situation detection unit 20 is an audio detection sensor installed in a room with a television, and is used as audio information such as utterance information of a viewer who is browsing an output target document such as a program guide or detailed program information. Based on the viewing status, the font size of the characters displayed in the character information display area may be automatically changed.
Specifically, when the situation determination unit 21 determines that words such as “character is small” and “difficult to see” are detected based on the information of the utterance of the viewer detected by the voice detection sensor, the font size Is greatly changed.
On the other hand, when the situation determination unit 21 determines that words such as “I want to see more” and “More details” are detected based on the information of the utterances of the viewer detected by the voice detection sensor, the font size is reduced. change.
Thus, it is determined from the viewer's utterance content that the viewer does not match the viewing status with the current font size, and the font size of the character displayed in the character information display area is determined by the viewer's desired The font size may be changed. Thereby, the viewer can more easily grasp the content of the output target document without stress with the font size of the character corresponding to the viewing situation.

Further, for example, the situation detection unit 20 may be used as program information acquisition means, and the font of characters to be automatically displayed in the character information display area may be changed according to the content of the program being viewed.
Specifically, based on the program information acquired by the situation detection unit 20, the situation determination unit 21 greatly changes the font size when the program being viewed is a program for the elderly.
In addition, for the kind of people who are watching the program, for example, the audience is set in advance according to the genre of the program, such as for historical drama for the elderly, animation for young people, Information such as increasing or decreasing the font size may be associated and managed, and determination may be made based on the managed information.

  As described above, the situation detection unit 20 is described as an example of a distance detection sensor, a face recognition sensor, or the like. However, this is only an example of the situation detection unit 20, and the situation detection unit 20 Anything that can detect the situation around the viewer or viewer.

  As described above, in the document output control apparatus 101 according to the second embodiment, the viewing status of the viewer is determined from the information detected from the sensor or the like, regardless of the operation of the change instruction from the viewer, and the character information By automatically changing the font size of the characters displayed in the display area and summarizing the output target document according to the changed font size, it is surely completed according to the viewing status of the viewer Can provide an output target document that can be understood.

In the second embodiment, the first embodiment may be applied.
Specifically, for example, in normal times, the situation determination unit 21 determines the viewing status of the viewer and automatically changes the font size of characters, and the display character number determination unit 13 acquires the font acquired from the situation determination unit 21. When the number of characters that can be displayed in the display area of the character information is determined based on the size and the operation reception unit 11 receives an instruction to change the font size of the character from the viewer, the display character number determination unit 13 receives the change instruction. The number of characters that can be displayed in the character information display area may be determined based on the font size of the characters.
