Description

Terminal that supports character enlargement, method of character expansion of terminal and recording medium recording the same

The present invention relates to a screen display of a terminal, and more particularly, to a terminal for supporting character enlargement, a character enlargement method of a terminal, and a recording medium recording the same.

Among the multimedia processing devices, the portable terminal has been a simple voice call means, but now has various functions such as DMB, MP3, camera, and game. Terminals are becoming smaller and smaller for the convenience of portability. In particular, as the size of the terminal becomes smaller, the liquid crystal size of the terminal becomes smaller.

In the conventional terminal, the zoom function is introduced as shown in FIG. 1 to enlarge the contents displayed on the small liquid crystal. However, to use the zoom function, the item 100 of the menu has to be cumbersome and the enlargement of the image files such as still images and videos. It is applied only to. Meanwhile, in the case of multimedia content including an image or text such as a menu, a mail, or a short message, since a plurality of characters are input in a limited screen space, it is difficult to check the plurality of characters generated in the liquid crystal. Furthermore, in order to check the contents displayed on the display screen, a person with poor eyesight, the elderly, or a disabled person can check the contents only when the screen is located close to the screen, which makes it difficult to use a terminal composed of an image or text.

The first technical problem to be achieved by the present invention is to provide a terminal that supports the enlargement of the character to increase the readability by enlarging the screen in various ways, in consideration of the connection of the words when the character is enlarged.

The second technical problem to be achieved by the present invention is to provide a method for enlarging a character of a terminal which can increase readability by enlarging the screen in various ways in a terminal with a small screen, considering the connection of words when enlarging the character. .

A third technical object of the present invention is to provide a recording medium that can be read by a computer system as a medium on which a program for executing the method of enlarging a terminal in a computer system is recorded.

According to an embodiment of the present disclosure, a terminal supporting character enlargement may include a memory unit configured to store a stream of characters; A display for displaying the stream of characters and an enlarged display area on a screen; A user input unit configured to receive a shape and size of a magnifying glass, a magnification of the magnifying glass, and receive coordinates of the magnifying glass when a magnifying glass function is selected; Displaying a magnified display area determined by the shape and size of the magnifier on the display, enlarging the characters of the coordinates of the magnifier by the magnification to display on the magnified display area, and when the magnifier reaches the edge of the screen A character magnification control unit configured to magnify at least one of the displayed character and characters connected to the stream from the memory unit by displaying the characters on the enlarged display area and displaying the characters on the enlarged display area together with the characters of the coordinates of the magnifying glass; And a word checker to determine whether characters are displayed in the enlarged display area.

In addition, the character enlargement method according to an embodiment of the present invention comprises the steps of displaying a stream of characters stored in the memory unit on the screen; If a magnifying glass function is selected, receiving a shape and size of the magnifying glass, a magnification and coordinates of the magnifying glass; Displaying an enlarged display area determined by the shape and size of the magnifying glass on the screen, and enlarging a character having the coordinates of the magnifying glass by the magnification and displaying the enlarged display area on the enlarged display area; And when the magnifying glass reaches the edge of the screen, when characters are displayed in the enlarged display area, at least one of the displayed characters and characters connected to the stream in the memory unit is enlarged to display the characters together with the coordinates of the magnifying glass. Displaying on the enlarged display area.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention illustrated below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below.

In mobile communication terminals such as mobile phones, the screen is small, and the text size of the text message and the size of the image are limited. Embodiments of the present invention add a magnifying glass function that can enlarge a portion or the entirety of the screen to the terminal so that it can be easily confirmed by enlarging small characters or images. Embodiments of the present invention may also be used to reduce and display a screen in order to express a lot of information on a small screen.

Embodiments of the present invention treat the text as a stream when the text is enlarged, and continuously move the magnifying glass to the right end of the screen to continuously display characters in the next line of the text even when the screen is out of bounds, thereby alternately magnifying the magnifying glass from side to side. Keep the text readable without moving. Conventionally, in order to read a character at the right end of the screen and to read a character in the next line, the magnifying glass had to be moved from the right end to the left end, but embodiments of the present invention can reduce such troublesomeness.

2 illustrates a terminal 200 supporting character enlargement according to an exemplary embodiment.

The display 210 displays text, pictures, and an enlarged display area. The display 210 includes a display device such as a liquid crystal (LCD) panel.

The user input unit 220 receives information such as selection of a magnifying glass function, shape and size of the magnifying glass, magnification of the magnifying glass, and the like. Specifically, after the magnifying glass function is selected, the user input unit 220 receives the shape and size of the magnifying glass, the magnification of the magnifying glass, and receives the coordinates of the magnifying glass. The user may select and set a shape of a magnifying glass such as a circle or a rectangle from a menu through the user input unit 220. Full screen magnification allows the size of the magnifying glass to occupy the entire screen. The user input unit 220 may be either a keypad or a touch panel.

The text magnification control unit 230 generates (displays) an enlarged display area determined by the shape and size of the magnifying glass on the display 210. The text magnification control unit 230 moves the coordinates of the magnifier according to the input of the user input unit 220, and enlarges the screen of the coordinates of the magnifier by the magnification and displays it in the enlarged display area. The screen magnification may be performed by adjusting a resolution of a screen corresponding to an area of the magnifier, a font size of a character, etc. from the current coordinates of the magnifier.

If the magnifying glass reaches the edge of the screen or a portion of the magnifying glass exceeds the edge of the text when the text is enlarged, the text magnification control unit 230 connects the text displayed in the enlarged display area to the stream (the text at the left end of the screen). Alternatively, the next line of characters is displayed in the enlarged display area. When displaying the characters connected by the stream, the character enlargement control unit 230 enlarges the characters up to the nearest punctuation of the characters displayed in the enlarged display area and the characters connected in the stream and the characters displayed in the enlarged display area and the characters connected in the stream without spaces. It is displayed together in the display area. Characters connected by the stream are extracted after checking whether the characters are stored as one stream in the memory unit 250. Whether or not the magnifying glass enlarges the characters depends on the word checker 240.

Hereinafter, a specific method of stream processing will be described.

In order to process the stream, the word checker 240 may recognize and process a word or a sentence from characters displayed on the screen. In addition, even text containing a line break symbol may be treated as streamed text without a line break symbol according to a user's selection. This may be necessary because the user usually reads the right end and the left end of the next line when reading a sentence.

Depending on the user's settings / selections, the entire text can be treated as a single stream. In this way, you can read the entire text as one line and read it from the beginning to the end of the text simply by moving the magnifying glass to the left or right. For example, the user may read all the text while moving the magnifying glass to the right by the size of the magnifying region of the magnifying glass.

When the magnifier enlarges one line, the text is considered one line. The text length is assumed to be t characters, and the size of the magnifying glass is assumed to be e characters. The magnifying glass can move in units of 1 to e characters.

Here, the size of the character may be based on bytes. If it is an ASCII code, the character is represented by 1 byte, and the character of Korean complete code is represented by 2 bytes. If the size of one character on the screen is based on 1 byte of characters, the Hangul complete character is 2 bytes and thus can be twice as large as ASCII characters. Of course, you can display characters of ASCII or Korean left-hand code in the same size. Alternatively, each character may have a different size depending on the size displayed. Therefore, since the size of the characters displayed on the screen varies depending on the character output method, it is assumed below that the minimum size (one byte character display size) of the characters displayed on the screen is the size of one character. However, if the Hangul complete character is displayed twice as large as the ASCII character, the Hangul complete character should be counted at twice the character size. That is, in this case, 2 * y ASCII characters can be displayed in a space capable of displaying y complete Korean characters. If the display size of each character is different, the display size of each character may be counted. Of course, if the displayed data is an image, the minimum unit displayed on the screen may be pixels.

If you display e characters of the text in the magnifying glass at the first position (the 0th character), you can zoom from the k * eth character to the (k + 1) e -1th character when you move the magnifying glass k times to the right. have.

If the left position of the current magnifying glass is the xth character of the text and the magnifying glass moves to the right by e characters, the end of the current magnifying glass is (x + e-1), so the magnifying glass is x + 2e-1 from the x + eth character. The first letter is enlarged and displayed. If only t characters are displayed to the end of the text and x + 2e-1 is greater than the end of the text, it can be represented to the end of the text, that is, up to t-1 if x + 2e-1> t-1.

The same applies to the leftward movement of the magnifying glass. If the left end coordinate of the current magnifying glass is the x-th character of the text, when the magnifying glass is moved to the left by e characters, the magnifying glass enlarges and displays the x-e th character to the x-1 th character. If the left end coordinate of the magnifying glass x-e <0, the magnifying glass enlarges from the 0th character to the x-1th character.

It is also possible to move the magnifying glass up and down in text stream processing. If the left end coordinate of the current magnifying glass is the xth character of the text, moving the magnifying glass up one line displays the magnifying glass from the character of the line immediately above the xth character on the original screen. That is, if the size of the original screen is M * N (the M-row N column, the 0th character to the M * N-1th character), it is displayed on the magnifying glass from the (x-N) th character of the screen. If (x-N) <0, display from the first character on the screen. In addition, when the magnifying glass is moved down one line, the magnifier is displayed from the character of the line immediately below the x-th character on the original screen. That is, it is displayed on the magnifying glass from the (x + N) th character of the screen. If the order of the last character of the text is t-1 (that is, the number of characters of the text is t), and (x + 2 * N-1)> t-1, up to the last character of the screen can be displayed. In the above formula, when the text fills the screen so that the number of characters is M * N, the value of t is M * N.

On the other hand, when the magnifier is set to enlarge and display several rows at once, the magnifier becomes a rectangle (or square) of size m * n (m rows n columns), and the magnifier can enlarge m * n characters. Assume Also assume that the text is t characters. The magnifying glass can move 1 to m * n characters. When you magnify m * n characters of text in the magnifying glass at the first position (the 0th character), if you move the magnifying glass k times to the right, the magnifying glass starts from the k * m * nth characters from (k + 1) m * n -1 The first character can be expanded.

Generalizing this, if the left coordinate of the current magnifying glass is the x-th character of the text, moving to the right by m * n characters, the magnifying glass expands from the x + m * nth character to the x + 2 * m * n-1th character do. If x + 2 * m * n-1> t-1, the magnifier zooms to the t-1th character only.

The same applies to the movement to the left. If the left coordinate of the current magnifying glass is the x-th character of the text, moving the magnifying glass to the left by m * n causes the magnifying glass to expand from the x-m * n-th character to the x-1th character. If x-m * n <0, the magnifying glass expands from the 0th character to the x-1th character.

In text messages or Hangul documents on a mobile phone, the line break symbol (enter key) is not used when creating a document, but text that has been wrapped due to screen constraints is processed as a stream when using a magnifying glass. When you move to the right, you naturally link the content of the text. In this manner, the magnifying glass does not have to be moved repeatedly from side to side in order to read text with the magnifying glass.

The character enlargement control unit 230 may be designed to display the coordinates of the magnifying glass on the display. When the character enlargement control unit 230 extracts and displays the next character in the enlarged display area, if the space in the enlarged display area is insufficient, the character enlargement control unit 230 moves the existing characters in the enlarged display area to the left and then displays the next characters connected to the existing characters. It can be designed to.

The word inspecting unit 240 determines whether characters are displayed in the enlarged display area and whether the displayed characters are complete words. The word checker 240 may be connected to a word dictionary that stores a vocabulary or a phrase when determining whether the words displayed in the enlarged display area are completed. According to another embodiment of the present disclosure, the word inspecting unit 240 checks whether the words displayed in the enlarged display area are completed, and if the words are not completed in the enlarged display area, regardless of line breaks on the stream. Characters connectable to the incomplete word are extracted from the memory unit 250. In this case, the character enlargement controller 230 may enlarge and display the characters extracted by the word inspector 240 together with the characters displayed in the enlarged display area. According to another embodiment of the present invention, the word inspecting unit 240 checks whether a word unit, a word, a phrase, or the like of the characters displayed in the enlarged display area is configured, and the character enlargement control unit 230 corresponds to a word, a word, a phrase, or the like. Words are grouped together and displayed in an enlarged display area.

The memory unit 250 stores a stream of characters. The stream of characters may be a character string previously input by the user, a character stream of a text message of the cellular phone, or the like.

According to another exemplary embodiment of the present invention, the characters displayed at the left and right ends of the screen may be processed as if they are connected to each other without processing the stream when the characters are enlarged. In this case, the character enlargement control unit 230 treats the screen as a cylinder.

For convenience of explanation, the size of the screen M * N (row M, column N, i.e. row number 0 to M-1, column number 0 to N-1), magnifier size m * n (row m, n column) , Rows 0 through m-1, columns 0 through n-1). The unit of the row or column may be pixel unit or character unit (for example, ASCII characters). Assuming that the position of the upper left corner of the current magnifying glass (square box) is on-screen coordinates (p, q), that is, p rows and q columns, if the magnifying glass is moved r rows downward, The coordinate of is [(p + r) mod M, q]. Here, mod refers to a modular operation that returns the remainder of a positive integer as a result of division. On the other hand, when moving the magnifying glass r rows upwards, the coordinates of the magnifying glass is [(p-r) mod M, q] if the screen is a cylindrical cylinder connected up and down. On the other hand, when the magnifying glass is moved in the s column to the right, the coordinates of the magnifying glass are [p, (q + s) mod N] if the screen is a cylindrical cylinder connected to the left and right. On the other hand, when moving the magnifying glass to the left s column, the coordinates of the magnifying glass is [p, (q-s) mod N] if the screen is a cylindrical connecting the left and right.

First, the terminal waits until the magnifying glass function is selected (S310).

When the magnifying glass function is selected, the shape and size of the magnifying glass and the magnification (magnification ratio or reduction ratio) of the magnifying glass are received (S320). When using a reduction ratio, the screen can be reduced to express a lot of information.

Next, an enlarged display area determined by the shape and size of the magnifying glass is generated (displayed) on the screen, and a part of the screen is enlarged and displayed on the enlarged display area (S330). All information displayed on the screen can be enlarged, such as a text message creation screen, a text message confirmation screen, and an image message confirmation screen.

When the coordinates of the magnifying glass move according to the user input, the screen as much as the enlarged area is enlarged by the magnification in the moved coordinates and displayed on the enlarged display area. If the magnifier is moved further to the right by some degree, the magnifier may appear immediately at the left end.

Next, when the magnifying glass reaches the edge of the screen, it is determined whether a character is displayed in the enlarged display area (S340). When the characters are displayed, the characters connected in the stream are displayed successively in the characters displayed in the enlarged display area (S350). In the case where the incomplete word at the end of the edge is displayed in the enlarged display area, the process (S350) includes the characters from the first space of the next character line until the spacing, or the characters until the next punctuation, or before the next punctuation. The method may include copying the characters and displaying them in the enlarged display area. In this case, whether or not the word is completed may be determined by determining whether the word of speech, the search is necessary, etc. using the word checker 240.

FIG. 4 is a detailed flowchart of the next line character display process S360 of FIG. 3.

First, the characters connected on the stream or the characters on the next line are extracted (S461). This process S461 is a process of extracting some of the characters included in the character stream data stored in the memory unit 250.

Next, if there is not enough space to display the characters copied in the next row in the enlarged display area (S462), the existing characters in the enlarged display area are moved to the left (S463).

Subsequently, in the space provided in the enlarged display area, characters passed to the next line by the next character or line break on the stream are displayed in connection with the existing characters (S464). If there is not enough space to display the next character on the stream or the character of the next line in the enlarged display area (S462), the characters connected to the stream or the character of the next line may be displayed immediately without shifting the existing character. .

The processing of text streams or processing of words, words, or sentences can be applied to the expansion of characters. Such a processing method may be designed to be changed by a method such as menu setting in the terminal.

5A to 5D show examples of enlarged characters.

When text is processed as a stream when characters are expanded, the start of the next line displayed on the screen can naturally be handled as being connected to the end of the previous line when line breaks occur due to screen constraints without line breaks. Of course, if there is a line break, stream processing that ignores the line break is also possible. In the stream processing of characters, it can be interpreted that the size of the screen changes due to the movement of the magnifying glass. Accordingly, when the horizontal axis of the screen is considered to be extended as the magnifier 520 moves to the right, the characters of the next row are naturally connected and displayed in the enlarged display area. In this case, the magnifier 520 may be processed in the same manner when the size of one line is appropriate but many are reduced. If the letter is moved by k characters according to the right side movement of the magnifying glass 520, the screen is also regarded as moved by k characters. Magnify the characters at the magnifier position on the virtual screen moved by k characters. In the virtual screen, the size of the horizontal axis is increased by k characters, so all line breaks in subsequent lines change accordingly. The next line of the magnifying glass moves forward by the letter k. Generalizing this, if the magnifying glass is expanding the i-th line, the j-th line after the i-th line is advanced by (j-i) * k characters. Where j> = i. When the magnifying glass 520 moves to the right by the size of k characters, the k characters on the left side of the magnifying glass are deleted and filled with new k characters displayed in a forward and enlarged manner in the enlarged virtual screen.

FIG. 5B shows a virtual screen 501 extending the original screen 500 horizontally in FIG. 5A. In FIG. 5A, since the number "14" constitutes one unit together with "hour" on the stream, the number "14" is grouped together in "14:00" and displayed in the enlarged display area 530.

Similarly, FIG. 5D shows a virtual screen 503 that extends the original screen 502 horizontally in FIG. 5C. In FIG. 5C, the letter “meeting room” constitutes a unit together with “in” on the stream, so that they are grouped together in “in the room” and displayed in the enlarged display area 530.

6A and 6B illustrate a process in which contents displayed in the enlarged display area 630 change as the magnifier 620 moves in FIG. 3. FIG. 6B illustrates a virtual screen 601 in which the original screen 600 is extended horizontally in FIG. 6A. In FIG. 6A, the number "is" constitutes one unit with "to" up to the nearest punctuation on the stream, and can be grouped together with "to" to be displayed in the enlarged display area 630.

7A to 7B illustrate an example of visually displaying the coordinates of the magnifying glass 720 on the enlarged display area 730.

7A to 7B show that the display of the enlarged display area 730 is changed when the magnifying glass 720 moves to the right by one space (character) on the screen 700. Bars that are displayed in bold on the edge or the magnifying glass shape 732 displayed in the enlarged display area 730 are moved in proportion to the degree of movement of the magnifying glass 720. When the position of the magnifying glass on the screen is displayed in the border of the enlarged display area 730 or in the enlarged display area 730, it is possible to confirm immediately which area of the screen is enlarged even without checking the position, thereby improving convenience. When the magnifier is enlarged and enlarged, the screen is obscured by the magnifier, so the position of the magnifier cannot be checked. However, applying this method enables accurate identification of the position of the magnifier on the screen.

The bars displayed on the edge of the enlarged display area 730 may be displayed on two sides by one horizontally and vertically or on all four sides. The bars displayed can be distinguished by the color or the thickness of the line. When the position of the magnifying glass 720 moves, the bars of the edge of the enlarged display area 730 are also dynamically displayed at the new position. Since the length of the bars indicates the location of the enlargement, the magnification can also be indicated.

In particular, when the magnifying glass spans the left and right boundaries of the screen as shown in FIG. 7B, the enlarged display area 730 also enlarges and shows the contents of the left and right ends of the screen. Thus, a bar or a magnifying glass shape indicating the left and right positions of the magnifying glass 720 is shown. 732 also spans the left and right ends of the screen. On the other hand, when the magnifying glass 720 is moved to the right by a certain degree, as shown in FIG. 7D, the magnifying glass 720 may immediately appear at the left end. At this time, the bar indicating the left and right positions of the magnifying glass 720 is at the left end of the enlarged display area.

7C shows a case in which the magnifying glass 720 is elliptical. When the shape of the magnifying glass 720 is not a rectangle, the minimum bounding rectangle (MBR) including the magnifying glass 720 is obtained to obtain coordinates of the position display section of the rectangle, and then the display section of the horizontal axis and the vertical axis display. The section may be displayed on the magnifying glass 720 or the enlarged display area 730. Bars 731 representing the coordinates of the magnifying glass 720 are displayed on the curved edge of the ellipsoidal enlarged display area 730. As illustrated in FIG. 7C, the shape 733 of the magnifying glass is reduced and displayed in the enlarged display area 730, so that the position on the screen of the magnifying glass may be intuitively grasped.

In addition, the position of the magnifier may be expressed by adding a shade or color to the area of the magnifier on the screen and changing the shade or color according to the position of the magnifier.

8A and 8B show examples of enlarging characters ignoring line breaks.

In the screen 800 of FIG. 8A, the "bulletin board" indicated by the magnifying glass 820 and the "on" of the next row are divided by a line break symbol. In such a case, simply displaying the enlarged display area 830 until the line break symbol is not displayed on the bulletin board. As in another embodiment of the present invention, if a word or word component is incomplete, line breaks are ignored. As shown in FIG. 8B, "on a bulletin board" is displayed in the enlarged display area 830 without moving the magnifying glass 820. can do.

In another embodiment of the present invention, when the user moves the magnifying glass to the right while reading the text, the complete word that can be displayed on the magnifying glass may be automatically moved to be displayed on the magnifying glass. (Hangul is moved to word unit because the unit of spacing is word word, and English is moved to word unit because spacing is word unit.) If the magnifier can express the sentence, it can be moved to the end of the sentence automatically. The position of automatic movement on the screen may be determined by a jump (blank) indicating the end of a word or a punctuation mark (period, comma, exclamation point, etc.) indicating the end of a sentence or phrase. The end of a sentence can be judged by the ending ending, or by the punctuation following the ending ending.

Meanwhile, the enlargement setting menu may be displayed on the screen of the terminal while the text is enlarged. In this case, when the enlargement setting menu is selected, the shape, size, magnification, etc. of the magnifying glass can be changed at any time. The magnifier may be moved automatically by the user's selection.

The invention can be implemented via software. Preferably, a program for executing the character enlargement method of the terminal according to the embodiments of the present invention may be provided by recording a program for executing in a computer on a computer-readable recording medium. When implemented in software, the constituent means of the present invention are code segments that perform the necessary work. The program or code segments may be stored on a processor readable medium or transmitted by a computer data signal coupled with a carrier on a transmission medium or network.

Computer-readable recording media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, DVD-ROM, DVD-RAM, magnetic tape, floppy disk, hard disk, optical data storage device, and the like. The computer readable recording medium can also be distributed over network coupled computer devices so that the computer readable code is stored and executed in a distributed fashion.
