Description

  The present invention relates generally to an information display device that displays a menu, title, icon, or the like of a content, and more specifically, a program information display device devised to display more program titles in a limited screen, and The present invention relates to an information display program.

  In recent years, an information display has been devised so that an electronic program guide (EPG) can be displayed based on data downloaded from a remote server or the like on a display of a personal computer, television, or mobile phone, and a list of programs currently being broadcast can be listed. The method is well established.

  Furthermore, a function for selecting a program to be reserved for recording based on an electronic program guide and a function for searching for a program that suits the user's preference from a vast amount of data by utilizing the characteristics of electronic information have been enhanced year by year.

  As a means and method for searching for a program in an information terminal, for example, there is a program search device described in Patent Document 1. According to this program search device, contents, dates, channels, and broadcast start of TV programs for a plurality of weeks are provided. Storage means for storing information including the time in advance is provided. Since this information is digitized, it can be easily retrieved by a microprocessor such as a CPU. Further, when the user of the program search device receives a designation of a program using a designation means, the search means is configured to search for a program that has received the designation from the storage means. Further, when the “weekly key” is operated, the same program can be searched for from the next week and later stored in the storage means. According to such a program apparatus, once a certain program is searched, there is an effect that it is possible to easily search for the same program to be broadcast after the next week.

  An example of the display of the electronic program guide in Patent Document 1 is as shown in FIG. 11, in which each channel information is displayed at the top of the horizontal column and the broadcast time zone is displayed at the vertical center of the screen. Each channel is arranged and displayed for each broadcast time zone, and what channel is broadcast on which channel during what time zone can be listed. The display method itself is the same as that for the conventional newspaper TV column, but there are restrictions on the display screen. For example, by operating the cursor etc. to move it outside the display area, the program to be displayed can be displayed. It is devised to change and update the area.

  There is also a program guide presentation device that makes the program guide more convenient (Patent Document 2). This program guide presenting device arranges each program broadcast within a predetermined time from the current time in order of broadcast start time for each channel based on the acquired EPG information, and each program arranged in order of broadcast start time for each channel is the same. By arranging in the display area of each channel located in parallel on the time axis, program information of programs currently being broadcast on each channel is arranged in a line at the beginning of each display area, and in order of broadcast start time for each channel. A current program table on which program information of each arranged program is displayed is generated and displayed on the display. As a result, it is possible for the user to easily check the program currently being broadcast on each channel, and to easily check the program that is being broadcast in the immediate vicinity of the program currently being broadcast on each channel. Play.

  In the electronic program guide of Patent Document 2, in order to display more information in a limited area, the relationship between the number of programs to be displayed in the program guide frame and the number of lines is determined according to a predetermined allocation pattern, for example. In addition to the basic pattern that assigns one program to one or more lines, a pattern that assigns two programs to 1.5 lines, a pattern that assigns three or more programs to two lines, etc. are prepared, and these are used appropriately. The device is designed to recognize a lot of information displayed in the area.

Japanese Patent No. 3130501 JP 2008-193153 A

  However, in recent years, program distribution forms have become enormous, as seen in cable broadcasting and on-demand distribution systems that span hundreds of channels. Displaying an enormous amount of program titles on a display with a limited display area installed in an information display device such as a terminal (so-called PDA) is so complicated that it cannot be solved even by the devices described above. Is increasing.

  In addition, the information display device itself is multi-functional. If it is equipped with a camera, it functions as a digital camera, and at the same time, it functions as a storage for storing stored images and an image viewer for viewing images. If it is provided with a section, it functions as a viewer that can further view moving images such as television. In addition, if you have an electronic dictionary or a mail function, you can use these applications, and a highly convenient startup menu that can call (start) many applications flexibly. A display (launcher) function is required.

  Therefore, an object of the present invention is to provide an information display device that can obtain good visibility even when a large amount of title information or the like is displayed on a limited display area. It is another object of the present invention to provide an information display device and an information display program having a startup menu display function that allows other applications to be easily selected regardless of what application is used.

An information display device according to the present invention is an information display device capable of displaying character information over a plurality of lines on a display, and includes a memory area for storing a plurality of title character strings, and the title characters on the display. It includes a arithmetic means you calculates the position coordinates for displaying the respective columns, a memory area for storing the position coordinates calculated by said calculation means, by the computing means, the position coordinates, the plurality The title character string is displayed twice for each line on the display, and a predetermined indent is inserted every other line. The second displayed title character string in each line is the first title character in each line. It is determined that centering display is performed in the remaining area where the columns are displayed.

Moreover, such information display program according to the present invention is a computer program executed by have you the information display device capable of displaying character information across multiple lines on a display, of the title character string on the display In order to calculate the position coordinates for displaying each of the position coordinates, the plurality of title character strings are displayed two per line on the display and a predetermined indent is inserted every other line. The title character string to be displayed secondly in each line includes a step of calculating so as to be centered and displayed in the remaining area where the first title character string in each line is displayed.

  According to the information display device and the like according to the present invention, good visibility can be obtained even when a large amount of title information is displayed on a limited display area in an EPG (electronic program guide), for example. Furthermore, since the information display apparatus according to the present invention has a startup menu display function that allows other applications to be easily selected regardless of what application is used, high operability can be realized.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for implementing an information display device and the like according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows an appearance of an information display device according to an embodiment of the present invention. The information display device 100 includes a housing unit 101, a display 102, and hardware buttons 103a and 103b provided on the left and right sides of the housing 101. The display 102 is composed of a liquid crystal display (LCD) or the like, and can display various information such as characters and images as will be described later. Further, a menu button or a software keyboard is displayed on the display 102, and an instruction (command) to the information display device can be obtained by touching the menu button or software keyboard with a finger or a touch pen (not shown). In this respect, the hardware buttons 103a and 103b are not essential components, but will be described as buttons having a certain function for the convenience of explanation of the present invention. Of course, these hardware buttons 103 a and 103 b can be replaced with menu buttons displayed on a part of the display 102.

  Although not shown in FIG. 1, the information display device 100 may include a microphone and a speaker as provided in many portable information terminals. In this case, it is possible to determine the voice of the user picked up from the microphone and use it as an input command.

  FIG. 2 shows a screen transition state of the information display device according to the embodiment of the present invention. In the present embodiment, for convenience of explanation, a menu display function is assigned to the hardware button 103a.

  In FIG. 2, when the hardware button 103 a is pressed while an arbitrary screen o is displayed, a strip-shaped menu 201 and a menu delete button 202 extending across the left and right edges of the screen are displayed at the approximate center of the display 102. Is displayed (screen m). In the screen m of FIG. 2, application start buttons A to E are displayed on the menu 201. Each application is started by touching or pressing each button, and the screen a to screen e (in FIG. d and screen e transition to (not shown).

  Further, when the menu delete button 202 is touched or pressed on the screen m, the menu 201 is not displayed and returns to the application screen used immediately before displaying the menu (that is, the screen o). Similarly, the menu 201 can be displayed on the screens a to e by pressing the hardware button 103a. However, if the menu delete button 202 is touched or pressed without selecting any application, the menu 201 is displayed. The screens a to e that were activated immediately before the display are respectively returned.

  FIG. 3 shows a specific example of the menu 201 displayed on the display 102. The menu 201 is a band-shaped pressing area extending substantially horizontally at the center of the display 102 over the left and right edges of the screen. In FIG. 3, “EPG” as menu A, “IMDb” as menu B, and menu C in FIG. “Home”, “Dlna” as menu D, and “Photos” as menu E are displayed. Here, although the boundary line between the five menus is not clearly shown in the figure, the pressed area is divided and managed by a user interface management program (not shown) so that the menu 201 is vertically divided into five equal parts. A corresponding application is started by touching or pressing an area where menu items are described. For example, when “EPG” is touched or pressed in the menu 201, an electronic program guide (described later) is started, and when “IMDb” is touched or pressed, information on not only movies and TV programs but also actors who can appear in these is searched. A browsable IMDb (Internet Movie Database) is activated, touching or pressing “Home” returns to the default screen (eg, remote control screen) of the information display device 100, and touching or pressing “Dlna” enables digital home appliances, etc. A Dlina (Digital Living Network Alliance) guideline for promoting mutual use is activated, and when “Photos” is touched or pressed, a photo album (for example, an album format) that displays a large amount of image data stored in the information display device 100 (Described later) is activated.

  As clearly shown in FIG. 3, in the state where the menu 201 is displayed, the screen immediately before starting the menu 201 is subjected to frost processing (by image processing) so that it can be seen through the frosted glass. This is also a feature of the present invention.

  Furthermore, the menu 201 can be scrolled to the left and right by dragging a band extending to the left and right ends of the screen 102, and other menus other than the above five menus can be displayed in a slide manner. .

  The menu erasure button 202 is displayed in the lower center of the screen in FIG. 3, and a downward triangle mark is written in a circle. When the button 202 is touched or pressed, the menu 201 is configured to be slid to the lower part of the screen while being left and right and to disappear from the screen. Alternatively, the menu erasure button 202 is designed to mark a triangle with an upward triangle mark, and the menu erasure operation is configured so that the menu erasure operation is slid to the top of the screen while being left and right and is erased from the screen. Also good. In addition, various image processes such as a screen wipeout process and a fadeout process can be used.

  FIG. 4 shows a specific example of the EPG screen displayed on the display 102. On the EPG screen (electronic program guide) 400, program titles for each time period obtained by user search are displayed in alphabetical order in principle. That is, when a search key 402 displayed on the upper right part of the screen 400 is touched or pressed, a program search function is activated, and a program is displayed on a software keyboard (not shown) displayed on a part of the display 102 (for example, the lower part). By inputting a part of a name or a keyword (program genre, performer, etc.), it is possible to search (narrow down) a program from a huge number.

  The search results are displayed for each time (403a to 403c) as shown in FIG. 4. For example, "America's Got Talent" (404a) and "World's Funniest Moments" (404b) are hit as corresponding programs at 8pm. is doing. In addition, as the corresponding programs at 9 pm, “The Philanthropist” (404c) and “Local Programming” (404d) are hit. Here, as a variation of the search function, it is also possible to configure the display color of the one that completely matches the input character (or keyword) or the one that is closest to the input character. For example, in FIG. 4, the title 404c is displayed in a color different from that of other titles.

  In the upper right of the screen 400, the time and day of the week acquired from the time measuring means are displayed (the screen indicates that it is 8:06 PM on Monday). The screen can be scrolled by a scroll bar 405. Further, a filter area 406 is displayed at the bottom of the screen, and the program (title) in the display area can be filtered. For example, in 406, there are six major categories: "News" (News), "Documentary" (Documentary), "Series" (Series), "Movie" (Movie), "Variety" (Variety), "Animation" (Animation) is displayed, and these can be narrowed down by sub-genre “Suspense”, “Comedy” (comedy), “Drama” (drama), “Action”, etc. The display portion is also provided with a changeover switch (not shown in FIG. 4) that can switch between displaying all the programs being broadcast or displaying them by broadcast station.

  FIG. 5 shows an embodiment of a photo album displayed on the information display device according to the present invention. The information display device 100 is provided with, for example, an SD card slot, a USB port, and the like, and can capture photo data, moving image data, and the like. In addition, since a DLNA client is also installed, data can be read from devices such as a personal computer and NAS via wireless.

  Then, the photo album 500 displays content such as photos and moving images in the main display area in order of, for example, shooting date and time (501a to 501f). These images can be scrolled vertically by a scroll bar 405. In addition, when an individual photo or the like is double-tapped, it can be enlarged and registered in a predetermined folder.

  The play list 503 displayed at the lower right part of the screen is a list view in which it is possible to determine which photos and the like are displayed as a slide show. A photo or the like selected by a double tap or the like is added to a list (memory) to be displayed as a slide show. The playlist 503 can be scrolled horizontally by an operation such as tracing with a finger or the like.

  FIG. 6 is a block diagram for explaining what kind of hardware the information display apparatus 100 is configured with. The operation of the information display device 100 is realized by the hardware operation described below.

  The information display device 100 can be broadly divided into an input unit 601 composed of hardware buttons 103a to 103b, a touch panel provided on the display 102, a microphone, and the like, and a hard disk, RAM, and the like for storing programs and data. A storage unit 602 configured by a ROM or the like, a central processing unit (CPU) 603 that performs various numerical calculations and logical operations by a program, a display unit 604 configured by a display 102, a chip, an electric system, and the like A control unit 605 for controlling the communication, a communication interface 606 including a slot for accessing the Internet, a port for performing optical communication, and the like, an output unit 607 such as a speaker, and the time measurement The timekeeping unit 608 and, if necessary, temperature, humidity, equipment posture, light quantity, etc. And a power supply unit 610 for supplying power to each module in the apparatus. These modules are appropriately divided into communication buses and power supply lines as needed (in FIG. 6, each line is appropriately divided for convenience. Are connected together as a connection 611).

  Further, the program or software necessary for implementing the present invention is normally installed or stored in a hard disk or the like in the storage unit 602, and when executing the program or software, all of the program or software is stored in the memory in the storage unit 602 as necessary. Alternatively, it is read out as a part of software module and is executed by the CPU 603.

  Next, a processing flow when EPG is selected from the menu 201 in the information display apparatus 100 will be described with reference to FIG. In S701, when the user presses the hardware button 103a, the process proceeds to S702, and the menu 201 is displayed on the display 102. Here, when the user selects an EPG (item A at the left end in FIG. 2) by touching or pressing on the menu 201 (S703), the information display apparatus 100 reads the EPG from a database such as an external server via the communication interface 606. Information is downloaded and temporarily stored in a hard disk or memory (storage unit 602) (S704). Next, positioning (coordinate calculation) is performed to determine how the program title included in the EPG information stored in the storage unit 602 should be displayed on the display 102 (S705). In this calculation, the program title is read from the EPG information stored in the storage unit 602, the position on the display 102 to be displayed for each title is calculated by the CPU 603, and the result is described later with reference to FIG. The list is stored in the memory (storage unit 602).

  This position calculation can be performed at an arbitrary timing. In other words, it may be performed immediately after downloading the EPG information, or the position calculation may be performed only for the hit title after narrowing down the title to be displayed by hitting the search request from the user. Alternatively, the position calculation may be performed only for the titles to be displayed on the display 102, and the position calculation may be performed each time for the titles that need to be newly displayed by the scroll operation. Therefore, the essence of the present invention is not impaired by the timing of such calculation.

  Then, when the position of each title to be displayed is determined, it is displayed on the display 102 (S706). Even when a new title needs to be displayed on the display 102 by the scroll operation, it is updated and displayed each time.

  The process is temporarily terminated depending on whether the menu 201 is called to activate another application or an application other than the electronic program guide is activated by an instruction unit (not shown) (S707).

FIG. 8 shows a processing flow explaining the title display position calculation process (S705) in FIG. 7 in more detail. When the position calculation process is started (S801), the size (Xmax, Ymax) of the area where the title can be displayed on the display 102 is read out to the memory (S802). For example, the display 102 has a display area of 800 × 600 dots, and subtracts the necessary display area for the time at the top of the screen, the search button, the scroll bar at the side of the screen, the filter area at the bottom of the screen, etc. If the area that can be used for display is 600x480 dots,
Xmax = 600, Ymax = 480
It becomes.

  Next, in S803, the program title is extracted from the EPG information downloaded from the external server. Alternatively, in S803, the title (M pieces) may be acquired for the title hit after the search request from the user. In step S804, variables X and Y for determining a position where each title is to be displayed are initialized. Also, a variable cnt for managing display lines is initialized.

  In the present invention, in principle, two titles are displayed per display line. Thus, as will be described later, a certain indent is inserted at the head of the title to be displayed in each line every other line.

  As described above, the process advances to step S805 to determine whether the line to be displayed is an even line or an odd line. For example, since cnt = 0 in the first line (odd line), it is determined that cnt is an even number and the display line itself is an odd line, and the process proceeds to S806. If cnt is an odd number, the display line is an even line. If it is determined that there is, the process proceeds to S807.

  If the display line is odd (cnt is even), the first title character string in that line is read from the EPG information in S806, and the position (X, Y) at which this title is to be displayed is stored in the memory together with the title character string. To do. The display position (X, Y) indicates the coordinates of the upper left corner of the title to be displayed with the upper left corner of the display area (the effective display area of the display) as the origin (0, 0). That is, the display position of the first title in the first line is (0, 0) because the variable (X, Y) is initialized. This value is stored in the memory together with the title character. Thereafter, in principle, the title display position of the first page of the odd-numbered line is X = 0, and Y is a value obtained by adding the height of one line to the previous Y position. The coordinate unit is, for example, a dot which is the minimum unit of the display pixels, but other unit elements may be used. Hereinafter, the coordinate unit is omitted.

  In step S808, the X coordinate of the second title in the odd row is calculated. The X coordinate of the second title of the odd line is the center of the second title of the odd line in the center of the remaining length obtained by subtracting the length used to display the first title of the odd line in Xmax of the display area. It is decided to be displayed. In other words, the second odd-numbered title is centered in the margin after the first odd-numbered title is displayed. Note that the Y coordinate of the second title in the odd row is a value obtained by adding the height of one row to the previously displayed Y coordinate. In step S810, the display position coordinates (X, Y) are written in the memory together with the title character string in the second odd-numbered row. Next, the process proceeds to S812, and the height h for one line is added to the variable Y in order to determine the next line height, and the process proceeds to S814 to increment cnt (plus 1).

  In S816, it is determined whether or not the calculation of the entire title has been completed. If completed, the process proceeds to S818, but if the title to be processed still remains, the process returns to S805.

  If it is determined in S805 that the display row is an even number (cnt is an odd number), the process proceeds to S807, and the X coordinate of the first title is determined. This is done by adding an indent (Ind) length to X. For example, when X is determined as the process of the second line after finishing the process of the first line, the previous value of X is 0 + Ind because X was 0 last time. In step S809, the display position coordinates (X, Y) are written in the memory together with the even-numbered first title character string, and the process advances to step S811.

  In S811, the X coordinate of the second title in the even line is calculated. The X coordinate of the even-numbered second title is the center of the remaining length of the even-numbered second title in the center of the remaining length minus the length used to display the even-numbered first title in Xmax of the display area. It is decided to be displayed. That is, the second title in the even-numbered line is centered and displayed in the margin after the first title in the even-numbered line is displayed. Note that the Y coordinate of the second title in the even line is a value obtained by adding the height of one line to the previously displayed Y coordinate. In step S813, the display position coordinates (X, Y) are written in the memory together with the title character string in the even-numbered second line. Next, the process proceeds to S815, and the height h for one line is added to the variable Y in order to determine the next line height, and the process proceeds to S817, where X is initialized and cnt is incremented (plus 1). To do).

  In S816, it is determined whether or not the calculation of the entire title has been completed. If completed, the process proceeds to S818, but if the title to be processed still remains, the process returns to S805.

  FIG. 9 shows a state in which the display position of each title determined by the flow shown in FIG. 8 is stored in the memory. In the memory area shown in FIG. 9, the display position of the extracted title is stored together with the title character string. In other words, the first title character string "America's Got Talent" is stored in the first row A column ("1A column", hereinafter the first row B column is simply referred to as "the second column"). The display position X coordinate x0 is stored in the 1B column, and the display position Y coordinate y0 is stored in the 1C column. Similarly, the second title character string “World's Funniest Moments” is stored in the 2A column, the display X coordinate x1 is stored in the 2B column, and the display Y coordinate y1 is stored in the 2C column. The 3A column stores the third title character string “Criminal Minds”, the 3B column stores the display X coordinate x2, and the 3C column stores the display Y coordinate y2. The fourth title character string “America's Next Top Model” is stored in the 4A column, the display X coordinate x3 is stored in the 4B column, and the display Y coordinate y3 is stored in the 4C column. The fifth title character string “Punk'd” is stored in the 5A column, the display X coordinate x4 is stored in the 5B column, and the display Y coordinate y4 is stored in the 5C column. The sixth title character string “So You Think You Can Dance” is stored in the 6A column, the display X coordinate x5 is stored in the 6B column, and the display Y coordinate y5 is stored in the 6C column.

  FIG. 10 visually explains how each title is displayed on the display 102 by the processing detailed above. According to FIG. 10 (A), two titles are displayed per line, and a fixed indent is added to the head of even lines, and the second title of each line displays the first title of that line. You can see how the remaining areas are centered and displayed. If there are too many title characters and the titles of two programs cannot be displayed on one line, the title display is separated by a certain length. It is also possible to make a configuration so that two programs can be displayed in one line by editing so as to be replaced with a one-character symbol. For example, a long title such as “We are the world, we are the children” (36 characters) is assumed to have a fixed length of 30 characters (comma and space character is also 1 character). “We are the world, We are” The text is edited to fit within 30 characters including “...

Next, in more detail based on FIG. 10B, if the display position (x0, y0) of the first title “America's Got Talent” in FIG. 9 is (0, 0), the second The display position (x1, y1) of the title “World's Funniest Moments” is
x1 = L1 + M12
y1 = 0
It becomes. However,
M12 = (Xmax-L1-L2) / 2
L1 is the length of the first title “America's Got Talent”, and L2 is the length of the second title “World's Funniest Moments”.

Similarly, the display position (x2, y2) of the third title “Criminal Minds” is represented by (Ind, h) (Ind is the indent length), and the display position (x3 of the fourth title “America's Next Top Model”). , Y3)
x3 = Ind + L3 + M34
y3 = h
It becomes. However,
M34 = (Xmax-Ind-L3-L4) / 2
L3 is the third title length, L4 is the fourth title length, and h is the height of one line.

Similarly, the position coordinates after (x4, y4) are determined. The calculation of the position coordinates can be configured such that the necessary amount is executed each time the scroll operation is performed. Generally speaking, the display coordinates (xTn1, yTn1) and (xTn2, yTn2) of the display titles Tn1 and Tn2 in the nth row (n is a natural number) are
If n is odd:
xTn1 = 0
yTn1 = (n−1) h
xTn2 = LTn1 + (Xmax−LTn1−LTn2) / 2
yTn2 = (n−1) h
If n is an even number:
xTn1 = Ind
yTn1 = (n−1) h
xTn2 = Ind + LTn1 + (Xmax-Ind-LTn1-LTn2) / 2
yTn2 = (n−1) h
It is. However, Xmax is the effective display width, h is the height of one line, LTn1 is the first title length in the line, LTn2 is the second title length in the line, and Ind is the indent length.

As described above, the essential features of the present invention have been described based on specific examples, but the following applications are also possible.
(1) A title displayed over a plurality of lines on the display 102 can be changed in display font or character color every other line. For example, odd lines are displayed at 10 pt and even lines are displayed at 16 pt, or odd lines are displayed in white and even lines are displayed in light blue. Such a display method further improves the distinguishability of each line.
(2) The indent described above can have fluctuations based on a known technique. For example, when the basic indent is 40 dots, the indent is randomly changed in a range of a constant width (for example, 10 dots) for each row. As a result, the display position of the title displayed first in each row also has a slight fluctuation.
(3) The centering described above can also have fluctuations based on a known technique.
