The present invention relates to a character display of a portable terminal, and more particularly, to an apparatus and a method for outputting more characters by changing a horizontal magnification ratio and a vertical magnification ratio of a character in a portable terminal.

In the portable terminal before using vector fonts, characters were displayed using bitmap data. In this case, since the bitmap data corresponding to the required size must be obtained for each type, the memory capacity occupied by the font data increases, so In order to reduce the memory size while using fonts, the use of vector fonts is increasing.

In the case of displaying a menu list using a list in the portable terminal, the selected list item may be given a point by enlarging the text size or changing the text background color. In addition, when displaying a website through a browser on a portable terminal, the screen is enlarged and reduced while outputting the screen in various sizes.

However, in the related art, since the screen of the portable terminal is smaller in size than a PC monitor, when the screen of the portable terminal is enlarged and displayed in a large sized character, the number of characters displayed in one screen is reduced. In this case, if the font size is simply enlarged using a vector font, the width and height of the text are increased at the same time as the text size is increased, thereby reducing the number of characters that can be displayed on one line. In the case of lists, the longer the text that is contained in an item, the harder it is to read at a glance, and even if the text is a slide, the readability of large letters is inevitably reduced.

Therefore, in the case of large letters, even if the width of the text is a little small, it is not a big problem in reading the text. What is needed is an apparatus and method that can.

Accordingly, it is an object of the present invention to provide a character display apparatus and method for adjusting the font size by applying the flatness of vector characters by dynamic character resizing.

Another object of the present invention is to provide a character display apparatus and method for outputting more characters on one line when increasing the character size.

It is still another object of the present invention to provide a character display apparatus and method for outputting more characters than conventional ones when a large number of characters are to be printed on one screen.

According to a first aspect of the present invention for achieving the above objects, the character display device of the portable terminal comprises a font control unit for reducing the horizontal width of a character of a predetermined size or more by the instruction of the control unit, and the character display request And a controller for displaying a character according to the reduced horizontal width.

According to a second aspect of the present invention for achieving the above object, the character display method of the portable terminal is a process of reducing the width of the character of a predetermined size or more by the instruction of the control unit, and when the character display request, the reduction And displaying the character according to the horizontal width.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention will be described with respect to the apparatus and method for displaying the text to output more characters on a line by applying the font, the plane to the vector font character.

1 is a block diagram illustrating an apparatus for displaying a text by adjusting a text aspect ratio according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the controller 101 controls the overall operation of the terminal. For example, when performing a process and control for voice call and data communication, and displaying a menu list using a list according to the present invention in addition to the usual functions, or outputting a certain length of text on a small screen, The font adjusting unit is instructed to adjust the ratio between the horizontal and vertical characters of the text by dynamic resizing, and a function of displaying the text on the display unit 103 is processed.

The display unit 103 displays status information (or indicators) generated during the operation of the terminal, limited numbers and characters, moving pictures, still pictures, and the like. The display unit 103 may use a color liquid crystal display (LCD).

The key input unit 105 includes numeric keys 0 to 9, menu keys (menu), cancel keys (clear), confirmation keys, call keys (TALK), end keys (END), Internet access keys, navigation keys (up / down). Down / left / right) and a plurality of function keys, and provide key input data corresponding to a key pressed by the user to the controller 101.

The interface module 107 converts a radio frequency (RF) signal received through the antenna into a baseband signal and provides the same to the controller 101 or converts a baseband signal into a radio frequency signal and transmits the same through the antenna. For example, in the case of transmission, channel coding and spreading of data to be transmitted are performed, and in the case of reception, the function of despreading and channel decoding of a received signal is performed. .

The audio processor 109 connected to the controller 101 and the speaker and microphone connected to the audio processor 109 are voice input / output blocks used for a voice call. The audio processor converts the PCM data provided from the controller 101 into an analog voice signal and sends the same through the speaker, and converts the voice signal received through the microphone into PCM data and provides the same to the controller 101. .

The memory 111 stores a program for controlling the overall operation of the terminal and temporarily stores data generated during the operation of the terminal. System parameters and other storage data (telephone number, SMS message, image data, etc.) are stored. Character image information data according to the present invention is stored in the memory 111.

The font control unit 113 adjusts the ratio between the width and height of the characters according to the instruction of the control unit 101 to change the horizontal and vertical ratio of one character so that many characters enter a line of the screen. To give results. The ratio of horizontal horizontal reduction is adjusted according to the LCD screen size, character size, and the number of texts that can fit in one line.

2 is a flowchart illustrating displaying a character by adjusting a ratio of a character width to a portrait according to an exemplary embodiment of the present invention.

Referring to FIG. 2, if there is a dynamic resizing request for a character having a predetermined size or more in step 201, the process proceeds to step 203 considering the horizontal size of the character in consideration of the LCD screen size, character size, and the number of texts that can fit in one line. Zoom out.

If the character size dynamic resizing request is not performed in step 201, the process proceeds to the corresponding mode in which the ratio is enlarged in the same aspect ratio.

Thereafter, in step 205, when displaying a menu list using a list, or when text of a certain length needs to be output on a small screen, the flow proceeds to step 207 to read a character image from the memory according to the reduced horizontal value (length). do.

In operation 209, a menu list or a long sentence message is displayed on the display unit.

If the process proceeds to step 205 to display the menu list using the list, or if there is no need to output a certain length of text on a small screen, the process ends.

The algorithm of the present invention is then terminated.

FIG. 3 illustrates an example in which more characters are displayed on one line by adjusting a ratio between the width and length of characters when displaying a menu list using a list according to an embodiment of the present invention.

FIG. 4 illustrates an example in which more characters are displayed on one line by adjusting a ratio between a character width and a height when outputting a text of a constant length according to an exemplary embodiment of the present invention.

3 and 4, in the case of a, the horizontal × vertical enlargement ratio is enlarged at the same rate, so that fewer characters are displayed on one line than in the case of b. There are more characters displayed on one line than in the case of. This is because, when the screen of the portable terminal is enlarged, the horizontal size of the characters is enlarged at a rate lower than the enlargement ratio of the vertical size, thereby increasing the space for the number of characters displayed on the horizontal. In the case of large letters, even if the width of the text is a little narrow, it is not a big problem for reading the text. When the size of the text is enlarged, the readability can be improved by changing the vertical magnification ratio and the horizontal magnification ratio for the large letters.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

If you adjust the ratio between the width and height of characters by dynamic resizing, when you print a certain length of text on a small screen such as a mobile phone, especially when you enlarge the size of the selected item on a screen such as a list, more characters on one line There is an advantage that can output more information can be output.
