Description

  The present invention relates to a display device that displays a character string, a program that causes a computer to function as control means in the display device, and a display method that displays a character string.

  Conventionally, when characters are displayed on a display device such as a fluorescent display tube or a liquid crystal display, if all characters cannot be displayed due to insufficient display digits, a scroll display or the like is used. ing. Even in a conventional portable player, a stationary audio system, or the like, the number of characters that can be displayed in one line is small when the area of the display unit cannot be increased. For example, the number of characters that can be displayed per line is about 10 to 15 characters. In these audio devices, when displaying the music name, artist name, etc. of the music to be played back, the character string that cannot be displayed in one line is displayed by scrolling, displaying the line separately, etc. Through processing, the entire character string to be displayed is displayed.

  As a technique related to the display of the file name, a technique is also known in which the extension “.MP3” is omitted when displaying the file name of the MP3 file (see, for example, Patent Document 1).

JP 2002-343067 A

  However, as described above, since there are few display digits, when the entire character string is displayed by scrolling, some operation is continuously performed, and when the display contents continuously change, the scrolling is not in time. The display content is difficult to understand, and it may take time to select a desired operation based on the display content. For example, when it is necessary to confirm a plurality of music titles in a short time as in the case of music search, it takes a considerable time to scroll and display all the characters constituting each music title. Therefore, scroll display is not suitable for such confirmation work.

  Also, when displaying a single song name in separate lines, the area required for display increases as the number of lines increases, so other information related to the music displayed at the same time, The space for displaying the titles of the music before and after the adjacent display is reduced.

  Further, according to the technique of displaying the MP3 file name by omitting the extension “.MP3”, only the extension is an object to be omitted. However, when selecting or listening to a song, the title or artist of the song I often want to check the name, album name, etc. For this reason, even if only the extension is omitted, the space saving effect in grasping the title of the music or the like is small.

  An object of the present invention is to provide a technique capable of displaying more contents by a display means having a limited number of characters that can be displayed in view of the problems of the prior art.

  In order to achieve this object, a display device according to the first invention includes a display unit having a width capable of displaying a predetermined number of characters, and a control for displaying a predetermined character string for each line by the display unit. In the display device comprising the means, when the control means displays the character string for each line, each character string includes the number of characters constituting the character string more than the predetermined number and includes an alphabetic notation. When the character string is a character string, the character string is characterized by omitting the display of the character representing the vowel in the English character notation.

  The display device according to a second invention is the display device according to the first invention, wherein when the control means displays a character string from which the vowel is omitted, the vowel is displayed until a predetermined time elapses from the start of the display of the character string. The display is performed without omission, and then the display is performed without the vowels.

  In the display device according to a third invention, in the first or second invention, the control means omits a vowel in the character string so that the number of characters constituting the character string is equal to or less than the predetermined number. , It is performed on a part of words constituting the character string.

  The display device according to a fourth invention is characterized in that, in the third invention, the control means determines the partial words based on a predetermined priority.

  The display device according to a fifth invention is the display device according to any one of the first to fourth inventions, wherein the control means omits the vowels in the character string, and the first character of each word constituting the character string. It is characterized by not performing.

  The display device according to a sixth aspect of the present invention is the display device according to any one of the first to fifth aspects, wherein the control means includes a plurality of consecutive vowels in each word constituting the character string. Of the last vowels, the vowels are not omitted.

  A program according to a seventh invention causes a computer to function as control means in the display device according to any one of the first to fifth inventions.

  A display method according to an eighth invention is a display method comprising a control step of displaying a predetermined character string for each line by display means having a width capable of displaying a predetermined number of characters. In the process, when displaying the character string for each line, if each character string has the number of characters constituting the character string equal to or more than the predetermined number and includes an alphabetic notation, The display of characters representing vowels in is omitted.

  According to the present invention, it is possible to display a larger amount of content by using a display unit with a limited number of characters that can be displayed.

  FIG. 1 is a block diagram showing the configuration of an audio playback apparatus according to an embodiment of the present invention. As shown in the figure, this apparatus includes a system microcomputer 11 that controls each part of the apparatus and performs necessary information processing, a storage part 12 that stores music content files, and instructions from the storage part 12 in response to instructions from the system microcomputer 11. From the digital signal processor (hereinafter referred to as “DSP”) 13 that performs signal processing such as decoding, a DA converter 14 that converts a digital audio signal from the DSP 13 into an analog signal, and a DA converter 14 An amplifying unit 15 for amplifying an analog audio signal, an output unit 16 for outputting the audio signal amplified in the amplifying unit 15 to a speaker, an operation unit 17 for performing an operation for giving an instruction to the system microcomputer 11, and a system microcomputer Display that displays information that 11 presents to the user Equipped with a 18.

  The storage unit 12 includes a readable / writable mass storage device such as a hard disk or a flash memory. The output unit 16 includes a speaker, headphones, and other terminals for outputting to the outside. The storage unit 12 stores WMA and MP3 format music files. Each music file is accompanied by attribute information such as the album, genre, artist, etc. to which the music file belongs as metadata, and a desired music file is searched using this.

  FIG. 2 shows the external appearance of the audio playback apparatus of FIG. The part which concerns on the external appearance of the display part 18 and the operation part 17 is shown. The operation unit 17 includes a power button 21 for turning on / off the power, a volume button 22 for adjusting the output volume, and a multi-control button 23 for scrolling and selecting a screen. A list of selection items that can be selected by the user is displayed on the display unit 18.

  When selecting a selection item, a desired selection item is indicated by the cursor. The multi-control button 23 includes an upper button and a lower button for moving the cursor, a selection button for selecting an instructed selection item, and the like. The selected item indicated by the cursor is highlighted. That is, the highlight display is a cursor. When the up button or the down button is pressed, the system microcomputer 11 moves the cursor up or down (a direction orthogonal to the row direction) on the list of selection items. At that time, by scrolling the list up and down as necessary, even when the number of selection items is larger than the number that can be displayed on the display unit 18, it is possible to position the cursor with respect to an arbitrary selection item. .

  When the user presses the upper button or the lower button, the designated selection item is sequentially switched to the upper or lower selection item in the list. Therefore, when the desired selection item is highlighted, the upper button or the lower button is displayed. The highlighted selection item can be selected by stopping the operation and pressing the selection button.

  On the display unit 18, various selection screens configured in a hierarchical manner are displayed. For example, items such as “artist”, “album”, and “genre” are displayed as selection items on the main menu screen at the top layer. When “Artist” is selected, an artist selection screen for displaying a list of each artist name as a selection item is displayed based on attribute information associated with each piece of music data stored in the storage unit 12. When an artist name is selected on this selection screen, an album selection screen with the album name belonging to the artist name as a selection item is displayed. When an album name is selected on this selection screen, a music selection screen is displayed that lists music names belonging to the album name as selection items. In this way, it is possible to search for music or the like to be reproduced via various selection screens. When a song name is selected on the song selection screen, playback of the song is started and a playback screen is displayed. On the playback screen, the name of the song being played is displayed.

  FIG. 3 shows a display example of the music name on the music selection screen and the playback screen described above. On the music selection screen and the playback screen, up to 18 characters can be displayed in one line because of the size of the display unit 18. When the title “Rock and Roll Music” is displayed in this one line, conventionally, “Rock and Roll Music” is displayed as shown in FIG. 10A, but in the present embodiment, it is shown in FIG. In this way, it is displayed in a format abbreviated as “Rck and Rll Msc”. That is, since “Rock and Roll Music” does not fit on one line, by omitting the vowels “a”, “i”, “u”, [e], “o” other than the head of each word, The character string is compressed within a discriminable range so as to fit in one line.

  According to this compression method, for example, when “restart” is displayed on a display device having a display digit number of 5 digits, it is conventionally “resta”, and it cannot be distinguished whether it is “restart” or “restarturant”. , “Rstrt” is displayed, it can be determined that the meaning is “restart”.

  FIG. 4 is a flowchart showing processing in the system microcomputer 11 that enables display of a character string in which such vowels are omitted. This process is performed when a predetermined key operation on the operation unit 17 is performed, or when a display on a predetermined line on the display unit 18 is switched in response to switching of the music being played to the next music. belongs to.

  That is, when the process is started, first, in step 41, it is determined whether or not a predetermined key operation has been performed or the reproduced music has been switched to the next music. If it is determined that the key operation or switching has been performed, the display content in the predetermined line is changed (step 42), so that the system microcomputer 11 displays the character string relating to the display content after the change in one line. It is determined whether or not display is possible. Displayable means that the number of characters constituting the character string does not exceed the number of characters that can be displayed in one line. If it is determined that display is possible, the process proceeds to step 51 where the changed character string is displayed as it is in the predetermined one line, and the process of FIG. 4 is terminated.

  If it is determined that display is not possible in one line, in steps 44 to 50, compression processing is performed on the character string related to the display content after the change. This compression processing is performed by sequentially examining the character string from the first character in accordance with the compression method described above and deleting characters to be omitted from the character string.

  That is, in step 44, if the character that is the subject of the investigation in the character string is the first character of each word constituting the character string, it is not subject to omission, so one character is sent. The following characters are to be investigated. Next, in step 45, it is determined whether or not the character to be investigated is the last character of the word. If it is determined that the character is not the last character, in step 46, whether the character to be investigated matches any of the vowels “a”, “i”, “u”, “e”, “o”. Determine if. If it is determined that they match any of them, in step 47, the character to be investigated is deleted and the process returns to step 45, and the investigation is continued with the next character as the investigation object. If it is determined in step 46 that it does not match any vowel, one character is sent in step 48 to make the next character the object of investigation, and the process returns to step 45 to continue the investigation.

  If it is determined in step 45 that the character to be investigated is the last character of the word, the process proceeds to step 49, and it is determined whether or not the investigation for all the words constituting the character string has been completed. If it is determined that the search has not been completed, the next word is set as the search target in step 50, the process returns to step 44, and the search is continued. If it is determined that all the words have been examined, in step 51, the predetermined one line is displayed using the compressed character string, and the process of FIG. 4 is terminated. If it is determined in step 41 that neither key operation nor switching has occurred, the display content in the predetermined line is maintained (step 51), and the processing in FIG. 4 is terminated.

  According to the present embodiment, when displaying a character string to be displayed in one line, such as a song name, if the number of characters constituting the character string exceeds the number of characters that can be displayed in one line, vowels in English notation Since the display of the character representing is omitted, more contents of the character string can be displayed in one line.

  FIG. 5 shows a display example in an audio playback apparatus according to another embodiment of the present invention. 1 and 2 are applied as they are as the configuration diagram of the apparatus. In this apparatus, omission of vowels in a character string is performed on some words constituting the character string so that the number of characters constituting the character string is equal to or less than the number of characters that can be displayed in one line. I am doing so. At this time, for which word the vowel is omitted is determined based on a predetermined priority order.

  That is, when the character string “Rock and Roll Music” consisting of 19 characters is displayed in one line where 18 characters can be displayed, if the priority order is set so that the word positioned in front of the character string becomes higher, The system microcomputer 11 displays this character string as shown in FIG. This is because if “o” is omitted in “Rock” having the highest priority and “Rck and Roll Music” is used, the number of characters becomes 18 characters and display is possible on one line.

  In this case, if the number of characters that can be displayed in one line is 17, “o” in “Roll” is further omitted. Also in this case, “a” in “and” is not omitted because it is the beginning of a word.

  On the other hand, when the above-mentioned character string “Rock and Roll Music” is displayed in one line where 18 characters can be displayed, if the priority order is set so that the word positioned later in the character string becomes higher, the system microcomputer 11 Displays this character string as shown in FIG. This is because if “voicing” is omitted in “Music” having the highest priority and “Rock and Roll Msc” is used, it is within 18 characters and can be displayed in one line. Also in this case, if the omission of vowels in “Music” is insufficient, the vowels are omitted for “Roll” having the next highest priority.

  It is possible to allow the user to set whether the higher priority is given to the word positioned before or after the character string.

  According to this embodiment, it is possible to omit vowels within a necessary range so as to fit in one line. Other points not mentioned are the same as those in the embodiment shown in FIGS.

  FIG. 6 shows a display example in an audio playback apparatus according to another embodiment of the present invention. 1 and 2 are applied as they are as the configuration diagram of the apparatus. In this apparatus, when a plurality of vowels are continuous in each word constituting the character string, the vowel is not omitted from the last of the plurality of consecutive vowels. About another point, it is the same as that of the case of embodiment of FIGS. 1-4.

  That is, when the character string “All You Need Is Love” consisting of 20 characters is displayed in one line where 18 characters can be displayed, according to the conventional method, it is displayed as shown in FIG. On the other hand, according to the present embodiment, the system microcomputer 11 omits “o” in “You” but leaves “u”, leaves behind “e” in “Need”, and further in “Love”. “O” and “e” are omitted in principle, and are displayed as shown in FIG.

  According to the present embodiment, when there are a plurality of consecutive vowels in each word, the last one of the consecutive vowels is displayed without being omitted. Can be prevented from becoming unknown.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, although not mentioned above, if the character string after the vowel is omitted cannot be displayed on one line, the character string after the vowel is omitted may be scroll-displayed. In this case, since the time required for scroll display is shorter than in the conventional case where the entire original character string is scroll-displayed, the contents of the character string can be grasped in a short time.

  Further, in the above description, the case where the music name is displayed has been described as an example. However, not only the music name but also the artist name and album name are displayed, and the display without the vowel can be performed as described above. .

  In the above description, when displaying a character string from which a vowel is omitted, the character string after the vowel is omitted is displayed from the beginning (steps 44 to 51). Instead, the character string is displayed. The character string may be displayed without omission of a vowel until a predetermined time, for example, 1 second elapses from the start of the display, and then the character string from which the vowel is omitted may be displayed. Further, this display order may be reversed.

It is a block diagram which shows the structure of the audio reproduction apparatus which concerns on one Embodiment of this invention. It is a figure which shows the external appearance of the apparatus of FIG. It is a figure which shows the example of a display of the selection item in the display part of the apparatus of FIG.
