<< Embodiment 1 >>
<Overview>
The content display device according to the present embodiment is characterized in that, when a part of the content is not displayed on the display unit, the display quality of the non-display part of the content and the display part having continuity is changed.
<Configuration>
FIG. 1 is a diagram illustrating an example of functional blocks of the content display apparatus according to the present embodiment. As shown in this figure, the “content display device” 0100 includes a “display unit” 0101, an “acquisition unit” 0102, a “determination unit” 0103, and a “change unit” 0104.

  The “display unit” has a function of displaying content. Examples of the content display device having a display unit include a personal computer, a television receiver, a mobile phone, a portable game device, a music player, and a PDA. Examples of the content to be displayed include content including characters and symbols, content including graphs and figures, content including photos and pictures, and the like. Specifically, as contents including characters and symbols, headline information of each home page displayed on the Internet search result screen of the web browser, each TV program information displayed in each program frame of the program guide screen, mail The destination / subject information of each mail displayed on the mail transmission / reception list on the application screen, the singing information of each music displayed on the music list on the music player screen, and the like. In these screens, when all characters and symbols cannot be displayed, symbols such as “...” Are often displayed at the end of the sentence. FIG. 2 is a diagram illustrating an example of the display of the related art. Examples of the content including graphs and graphics include graph information displayed in the display section of the spreadsheet application screen and graphic information displayed in the display section of the drawing application screen.

  Note that the number of contents to be displayed on the display unit does not have to be one, and an aspect in which a plurality of contents are simultaneously displayed in each display area is also included. For example, when displaying TV program information, one TV program information is displayed in one program display frame, and other TV program information is displayed in another program display frame. Also, when displaying the mail transmission / reception list, the address / subject information of one mail is displayed in one list section, and the address / subject information of another mail is displayed in another list section. This is also the case.

  Moreover, the type of content displayed on the display unit does not have to be one, and a mode in which a plurality of types of content are simultaneously displayed in each display area is also included. For example, there is a case where television program information is displayed in the program display area of the television screen and reserved program information is displayed in the reserved program display area.

  The “acquisition unit” has a function of acquiring content to be displayed on the display unit. As a mode for acquiring content, a mode in which content recorded on a recording medium such as a magnetic recording medium or an optical recording medium is read and acquired, or content is received and acquired via a network such as the Internet, a LAN, or a WAN. A mode, a mode of receiving and acquiring content via an antenna or a tuner, a mode of receiving and acquiring content input via an operation input device such as a keyboard, and the like. Note that content acquisition may be partial. For example, a mode in which only the portion displayed on the display unit of the content is appropriately acquired as necessary can be considered. In this case, the acquisition unit can output information indicating that there is a portion of content that has not been acquired (a portion of content that is not displayed).

  The acquisition unit can also specify and acquire a content unit. For example, all pages of a newspaper article may be acquired as a unit of content, or a page of a sports column in a newspaper article may be acquired as a unit of content. In addition, one entire photo may be acquired as a unit of content, or a part of one photo may be acquired as a unit of content. In this way, the unit of content is arbitrary, and various modes can be considered. In addition, as a specific means for specifying the content, it can be performed based on attribute information, pixel coordinate information, and the like included in the data.

  The “determination unit” has a function of determining whether there is a part of content that is not displayed on the display unit. For example, when the content is character information composed of a plurality of pages and only one page of character information can be displayed as the display area, it can be said that there is a portion of the content that is not displayed on the display unit. Even if the content is character information consisting of one page, it can be said that there is a portion of the content that is not displayed on the display unit even when a part of the area where the character information is displayed does not fit on the display screen.

  When the area where the content is displayed fits on the display screen, whether there is a part of the content that is not displayed is determined by the display size required to display the entire acquired content and the size of the display area of the display unit This can be done by comparing. More specifically, comparing the size that can be realistically (physically) mapped to the allocated area of the video memory and the size when the entire content is logically (virtually) mapped, A determination can be made based on whether or not the display area is in an inclusive relationship.

  When the content acquired by the acquisition unit is partial, information indicating that the content is partial acquisition is received from the acquisition unit, and it can be determined that the content is a part of the entire content. In addition, when a part of the area where the content is displayed does not fit on the display screen (when it cannot be displayed on the screen), it is not displayed based on the current coordinate information of the area where the content is displayed. It can be determined that there is a content portion. In addition, when the position, size, or shape of the content display area is changed, the determination process can be dynamically performed each time. For example, when the user performs an operation of reducing the window that is the display area of the map image, it is determined whether a part of the map image is not displayed. It is also possible to perform determination processing at predetermined time intervals using a timer.

  FIG. 3 is a diagram illustrating an example of determination processing of the determination unit when the content displayed on the display unit is composed of characters. First, in step S0301, the number of characters of the acquired content is calculated. Next, in step S0302, information on the number of characters entering the content display frame is acquired. In step S0303, the number of characters of the acquired content is compared with the number of characters that enter the content display frame. Here, if the number of characters of the acquired content is larger than the number of characters entering the content display frame, the process proceeds to step S0304A, and a determination result that there is a portion of the content that is not displayed is output. On the other hand, if the number of characters of the acquired content is less than or equal to the number of characters entering the content display frame, the process proceeds to step S0304B, and a determination result that there is no content portion that is not displayed is output.

  FIG. 4 is a diagram illustrating an example of determination processing of the determination unit when the content displayed on the display unit is a picture or a photograph. First, in step S0401, the vertical and horizontal sizes of the acquired content are acquired. Next, in step S0402, the vertical and horizontal sizes of the content display frame are acquired. In step S0403, the vertical and horizontal sizes of the acquired content are compared with the vertical and horizontal sizes of the content display frame. Here, if the vertical and horizontal sizes of the acquired content are larger than the vertical and horizontal sizes of the display frame of the content, the process proceeds to step S0404A, and a determination result is output that a part of the content in the vertical and / or horizontal directions is not displayed. To do. If the vertical and horizontal sizes of the acquired content are equal to or smaller than the vertical and horizontal sizes of the content display frame, the process advances to step S0404B to output a determination result that the entire content is displayed.

  The “change unit” has a function of changing the display quality of the non-display content portion and the display content portion that is continuous with the non-display content portion when it is determined that there is a content portion that is not displayed. Here, the non-display content portion refers to a portion of content that is not displayed, and the display content portion refers to a portion of content that is displayed. Further, “the continuity between the non-display content portion and the display content portion” means that the non-display content portion and the display content portion are logically or physically continuous. For example, when the content is composed of characters or the like, it means that the relationship should be read continuously, and when the content is composed of figures or photos, it means that the content should be viewed continuously.

  Also, changing the display quality of the content display portion means changing the display quality of the elements constituting the content display portion, its background, display frame, and the like. Here, elements constituting the display portion of the content include characters, symbols, graphs, figures, photographs, pictures, and the like. The display quality includes the size and shape of display elements and display frames, patterns, colors, patterns of display backgrounds, colors, transparency and resolution of display elements, brightness, texture, and the like.

  FIG. 5 is a diagram illustrating an example of processing of the changing unit when the content displayed on the display unit is composed of characters or the like. First, in step S0501, the processing result of the determination unit that determines whether there is a character that is not displayed on the display unit is acquired. If it is determined that there is a character that is not displayed, the process advances to step S0502. If it is determined that there is no character that is not displayed, the process ends. In step S0502, a process of gradually increasing the transparency of a plurality of characters displayed at the end of the content display area is performed. FIG. 6 is a diagram showing a display result by the above processing. As shown in this figure, by increasing the transparency of the character from the “×” part of “Team AZ × Chi”, consecutive characters that are not displayed can be displayed without displaying an ellipsis such as “...”. You can see at a glance. First, FIG. 7 is a diagram illustrating an example of a display result when the display form of the display frame defining the display area is changed instead of increasing the transparency of the characters displayed at the end of the display area. It is possible to indicate that non-displayed characters continue by changing the display form of the content display frame as shown in FIG.

In addition, when it is determined that there is a part of the content that is not displayed on the display unit, the change unit displays the content part displayed at the end of the display area of the content (the character, figure, or picture at the end of the display area). It is also possible to change the resolution of a part) or change the luminance of the background of the content portion displayed at the end of the display area. It is also possible to slightly vibrate the content portion displayed at the end of the content display area, blink the display portion, or change the color over time.
<Specific configuration>

Each hardware is mutually connected by “system bus” 0812, and can exchange signals.

The “tuner” corresponds to a terrestrial digital tuner capable of receiving terrestrial digital broadcasting and a BS / CS digital tuner capable of receiving BS / CS digital broadcasting. The “demodulation circuit unit” demodulates the broadcast signal received by the tuner and outputs the demodulated signal, for example, as an MPEG transport stream (TS) to the processing arithmetic unit. The “processing arithmetic device” corresponds to, for example, a CPU, GPU, system LSI, or the like. In the processing arithmetic unit, for example, a PES (Packetized Elementary Stream) packet, which is encoded video / audio data, and electronic program guide data (EPG data) are separated from signals output from the demodulation circuit unit. Further, video / audio data is decoded from the PES packet. In addition, various format conversion processing and multi-screen processing are performed on the video data. Further, the graphic data (for example, electronic program guide data) is edited and displayed in a superimposed manner as necessary. The “memory” stores programs, work data, and data for video / audio / graphics. Examples of the memory include an EEPROM and an SDRAM. The “display controller” D / A converts display data transmitted from the “processing arithmetic device” and controls the “display” to display an image. The “voice processing circuit” D / A converts voice data transmitted from the “processing arithmetic device” and controls the “speaker” to output voice.
<Process flow>
FIG. 9 is a diagram illustrating an example of a processing flow of the content display apparatus according to the present embodiment. The processing described below is performed by executing a predetermined program on the content display device, and the program can be stored in a storage medium. First, in step S0901, content to be displayed is acquired (acquisition step). Next, in step S0902, it is determined whether there is a portion of content that is not displayed (determination step). If it is determined that there is a content portion that is not displayed, the process advances to step S0903A. If it is determined that there is no content portion that is not displayed, the process advances to step S0904B. Next, in step S0903A, the display quality of the display content portion that is continuous with the non-display content portion is changed (change step). Next, in step S0904A, the display content portion whose display quality is changed is displayed (display step). In step S0904B, the entire content is displayed.
<Effect>
The present invention configured as described above makes it possible to grasp at a glance that there is a non-displayed content portion by changing the display quality of the non-display portion of the content and the display portion that is continuous. Become. In addition, since it is not necessary to use an ellipsis, as much information as possible can be displayed within a limited display area. Further, when displaying a figure, a picture, or the like, it is possible to grasp at a glance that there is a portion that is not displayed even if all display elements are not displayed within a predetermined display area.
<< Embodiment 2 >>
<Overview>
The content display device of the present embodiment is basically the same as that of the first embodiment, but when a part of the content is not displayed on the display unit, the content being displayed is continuous with the non-displayed content. The display form of characters, backgrounds, display frames, and the like constituting the image is partially changed.
<Configuration>
FIG. 10 is a diagram illustrating an example of functional blocks of the content display device according to the present embodiment. As shown in this figure, the “content display device” 1000 includes a “display unit” 1001, an “acquisition unit” 1002, a “determination unit” 1003, and a “change unit” 1004. “Display form changing means” 1005 is provided. Hereinafter, “display mode changing means” which is different from the first embodiment will be described.

  The “display form changing means” has a function of changing one or more display forms of characters, symbols, graphs, figures, photographs, pictures, backgrounds, and display frames constituting the content as a change in display quality. Here, changing any one or more display forms of characters or the like constituting the content means changing the size, shape, pattern, color, or the like of the characters.

  FIG. 11 is a diagram illustrating an example of processing of the display form changing unit when the content displayed on the display unit is composed of characters or the like. First, in step S1101, the processing result of the determination unit that determines whether there is a character that is not displayed on the display unit is acquired. If it is determined that there is a character that is not displayed, the process advances to step S1102. If it is determined that there is no character that is not displayed, the process ends. Next, in step S1102, a process of setting the sizes of a plurality of characters displayed at the end of the content display area to be smaller in stages is performed. Next, in step S1103, characters that should not have been displayed are sequentially assigned to the space generated by reducing the size of the plurality of characters displayed at the end of the display area. Here, the size of a new character to which a space is allocated is also set small. FIG. 12 is a diagram illustrating an example of a display result obtained by the above processing. As shown in this figure, by reducing the size of the character from the “O” part of “Investigating Kintai Bridge”, the content can be configured without displaying an ellipsis such as “...” It can be seen at a glance that there are continuous portions other than the portion where the characters are displayed.

  It is also possible to set so that the background color at the end of the content display area gradually approaches the character color. For example, if the character color is black and the background color is white, the background color is set to gradually change from white to black at the display end. If the character color is red and the background color is blue, the display end is set. The background color is set to change stepwise from blue to red. FIG. 13 is a diagram illustrating an example of a display result when processing is performed so that the background color at the end of the content display area gradually approaches the character color. As shown in this figure, by bringing the background color closer to the color of the display character from the “band” part of “Kintai Bridge”, the content can be displayed without displaying an ellipsis such as “...”. It can be seen at a glance that the constituent characters are continuously present other than the displayed part. Although the background color is changed in the above, it is also possible to set the character color at the display end of the content to gradually approach the background color.

It is also possible to change the shape of the portion of the display frame surrounding the content that is near the end of the content display area. FIG. 14 is a diagram illustrating an example of a display result when the processing is performed. As shown in this figure, ellipsis symbols such as "..." are displayed by turning the shape of the display frame part near the "tone" part of "tone band". Even if it is not, it can be seen at a glance that there are continuous portions other than the portion where the characters constituting the content are displayed.
<Process flow>
FIG. 15 is a diagram illustrating an example of a processing flow of the content display apparatus according to the present embodiment. The processing described below is performed by executing a predetermined program on the content display device, and the program can be stored in a storage medium. First, in step S1501, content to be displayed is acquired (acquisition step). Next, in step S1502, it is determined whether there is a portion of content that is not displayed (determination step). If it is determined that there is a content portion that is not displayed, the process advances to step S1503A. If it is determined that there is no content portion that is not displayed, the process advances to step S1504B. Next, in step S1503A, the display form of one or more of characters, symbols, graphs, graphics, photographs, pictures, backgrounds, and display frames constituting the content of the display content portion that is continuous with the non-display content portion is changed. (Change step: display form change). Next, in step S1504A, the display content portion whose display quality is changed is displayed (display step). In step S1504B, the entire content is displayed.
<Effect>
The content display device according to the present embodiment can recognize at a glance that there is a non-displayed content portion by changing the display form of characters or the like constituting a display portion that is continuous with the non-display portion of the content. It becomes possible. In addition, since it is not necessary to use an ellipsis, as much information as possible can be displayed within a limited display area. Further, when displaying a figure, a picture, or the like, it is possible to grasp at a glance that there is a portion that is not displayed even if all display elements are not displayed within a predetermined display area.
<< Embodiment 3 >>
<Overview>
The content display apparatus according to the present embodiment is basically the same as that of the first embodiment, but is characterized in that the display quality of the displayed content is changed according to the amount of non-displayed content.
<Configuration>
FIG. 16 is a diagram illustrating an example of functional blocks of the content reproduction apparatus according to the present embodiment. As shown in this figure, the “content display device” 1600 has a “display unit” 1601, an “acquisition unit” 1602, a “determination unit” 1603, and a “change unit” 1604. It has a “non-display content amount acquisition unit” 1605 and a “quantity change unit” 1606. Hereinafter, “non-display content amount acquisition means” and “quantitative change means” which are different from the first embodiment will be described.

  The “non-display content amount acquisition means” has a function of acquiring the amount of the non-display content portion. Examples of the amount of the non-displayed content portion include characters and symbols that are not displayed on the display unit when the content is composed of characters, symbols, the number of words, and a ratio that is not displayed with respect to the whole. In addition, when the content is composed of a figure, a photograph, a picture, or the like, the size of a portion that is not displayed on the display unit, the ratio that is not displayed with respect to the whole, or the like can be given. The non-display content amount acquisition means counts the number of characters, symbols, and words that are not displayed on the display unit, calculates the size of a graphic or photo part that is not displayed on the display unit, and Get the quantity. Note that, in the process of the determination unit, when the amount of the content portion not displayed on the display unit is calculated, the non-display content amount acquisition unit may acquire the result of the calculation process.

  The “quantity changing means” has a function of changing the display quality of the continuous display content portion according to the acquired amount of the non-display content portion. Here, changing the display quality according to the amount of the non-displayed content portion means changing the display form of characters or the like constituting the content according to the amount of the non-displayed content portion.

  FIG. 17 is a diagram illustrating an example of processing of the non-display content amount acquisition unit and the adaptation unit when the content displayed on the display unit is composed of characters. First, in step S1701, the processing result of the determination unit that determines whether there is a character that is not displayed on the display unit is acquired. If it is determined that there is a character that is not displayed, the process advances to step S1702. If it is determined that there is no character that is not displayed, the process ends. Next, in step S1702, a process of counting the number of characters not displayed on the display unit is performed. Next, in step S1703, the display form of the display frame is determined according to the counted number of characters, based on a table that associates the number of characters that are not displayed and the type of display form of the display frame. Next, in step S1704, the characters constituting the content are displayed using the determined display frame data. 18, 19 and 20 are diagrams showing examples of display results obtained by the above processing. In the example of FIGS. 18 and 19, since the number of characters not displayed on the display unit is larger in the second stage than in the first stage, the display frame is displayed so that the corner of the display frame is turned up. For this reason, not only can it be seen at a glance that there are characters that are not displayed in the first and second display frames, but there are relatively many characters that are not displayed in the second display frame. I can judge. In the example of FIG. 20, the color of the turned portion of the display frame is displayed differently according to the number of characters not displayed in the display frame.

  Further, the scale changing means can change the color and luminance of the display content portion according to the acquired amount of the non-display content portion. For example, when the content is composed of characters or the like, it is conceivable that the display characters having continuity are changed to a lighter or darker color as the number of characters that are not displayed increases. In addition, when the content is composed of a picture or a photograph, it is conceivable to increase or decrease the luminance of the continuous display portion as the size of the non-displayed portion increases.

In addition, the scale changing means can change the range of the display content part that changes the quality of display according to the amount of the acquired non-display content part. For example, it is conceivable that the larger the number of characters that are not displayed, the larger the range in which the quality of display is changed among the displayed characters. Specifically, when the amount of the non-display content portion is smaller than the display content portion, the display quality of the portion 1/8 from the end of the display content portion is changed, and the amount of the non-display content portion is larger than that of the display content portion. If there are too many, the display quality of the ¼ portion from the end of the display content portion is changed.
<Process flow>
FIG. 21 is a diagram illustrating an example of a processing flow of the content display apparatus according to the present embodiment. The processing described below is performed by executing a predetermined program on the content display device, and the program can be stored in a storage medium. First, in step S2101, content to be displayed is acquired (acquisition step). Next, in step S2102, it is determined whether there is a portion of content that is not displayed (determination step). If it is determined that there is a content portion that is not displayed, the process advances to step S2103A. If it is determined that there is no content portion that is not displayed, the process advances to step S2105B. Next, in step S2103A, the amount of the non-display content portion is acquired (non-display content amount acquisition sub-step). Next, in step S2104A, the display quality of the display content portion is changed according to the acquired amount of the non-display content portion (quantitative change substep). Next, in step S2105A, the display content portion whose display quality is changed is displayed (display step). In step S2105B, the entire content is displayed.
<Effect>
In addition to the effects of the first embodiment and the like, the content display device of the present embodiment changes the display quality of the continuous display content portion according to the amount of the non-display content portion, so that the content portion that is not displayed It becomes possible to grasp at a glance how much there is.

As shown in this figure, the “content display device” 2200 includes a “display unit” 2201, an “acquisition unit” 2202, a “determination unit” 2203, a “change unit” 2204, and a “GUI operation reception unit” 2205. The GUI operation accepting unit has “continuous display means” 2206. Hereinafter, the “GUI operation receiving unit” and the “continuous display unit” which are different from the first embodiment will be described.

  The “GUI operation reception unit” has a function of receiving a GUI operation input to the display unit. Here, the GUI operation input means that a user performs an instruction operation with a pointing device, a finger, or the like on a portion where content is displayed on the display unit.

  The “continuous display means” has a function of displaying all or a part of the non-display portion when the display portion receives a GUI operation input for the portion changed by the changing portion. The GUI operation input to the part changed by the changing unit refers to an operation for instructing the part changed by the changing unit with a pointing device or a finger.

FIG. 23 is a diagram illustrating an example of processing of the continuous display unit when the content displayed on the display unit is composed of characters or the like. First, in step S2301, it is determined whether a GUI operation input for the part changed by the changing unit has been received by the GUI operation receiving unit. If it is determined that the request has been received, the process advances to step S2302. If it is determined that it has not been received, the process waits. Next, in step S2302, switching is performed so as to display characters that were not displayed in the part that received the GUI operation input. FIG. 24 is a diagram illustrating an example of a display result obtained by the above processing. In the example of this figure, the character display of the part that received the GUI operation input is scrolled to hide the characters that have been displayed so far in order from the front end, and the characters that have not been displayed in order from the front end. To display. FIG. 25 is a diagram illustrating another example of the display result obtained by the above processing. In the example of this figure, the character group that has been displayed in the display frame so far is replaced with a character group that has not been displayed.
<Process flow>
FIG. 26 is a diagram showing an example of the processing flow of the content display apparatus of this embodiment. The processing described below is performed by executing a predetermined program on the content display device, and the program can be stored in a storage medium. First, in step S2601, content to be displayed is acquired (acquisition step). Next, in step S2602, it is determined whether there is a portion of content that is not displayed (determination step). If it is determined that there is a content portion that is not displayed, the process advances to step S2603A. If it is determined that there is no content portion that is not displayed, the process advances to step S2604B. Next, in step S2603A, the display quality of the display content portion that is continuous with the non-display content portion is changed (change step). Next, in step S2604A, the display content portion whose display quality is changed is displayed (display step). In step S2604B, the entire content is displayed. Next, in step S2605A, it is determined whether or not a GUI operation input has been received for a portion whose display quality has been changed in the change step (GUI operation reception determination step). If it is determined that the request has been received, the process advances to step S2606A. If it is determined that it has not been received, the process waits. Next, in step S2606A, all or part of the non-display content is displayed (continuous display step).
<Effect>
In addition to the effects of the first embodiment and the like, the content display device of the present embodiment can easily display a content portion that is not displayed by a GUI operation input.
