Description of the invention: [Technical field to which the invention pertains] The present invention is a method for enlarging a displayed word, and more particularly relates to magnifying and displaying a vector font in a pop-up window. [Prior Art] Fig. 5 is a system block diagram of a conventional subtitle processing apparatus, together with a subtitle decoder and a display device. In Fig. 5, 51 denotes a subtitle processing means, 52 denotes a subtitle decoder which supplies original subtitle data to the subtitle processing means, and 53 denotes a subtitle in which the display means displays the processing. The caption processing device 51 further includes the following components: 510 denotes a caption input portion that inputs display properties and subtitle image data from a subtitle decoder 52 of a DTV IRD. 511 denotes a control portion, such as a remote controller, for a TV viewer to select a subtitle size by an enlargement or reduction button selected for the controller. 512 denotes a pixel upsampling portion, which is expanded by one pixel to four pixels. 513 denotes an image reproduction portion which calculates a cut-off point of the subtitle image based on the relationship between the width of the Chinese font and the width of the display, and reproduces two subtitle images from one input subtitle image. 514 represents a background color search portion that finds the background color of the 5 1334588 of the subtitle image. 515 represents a one-pixel downsampling portion that reduces four pixels to one pixel. 516 denotes a position adjustment section which adjusts the display position of the subtitle image to avoid overlap and center alignment. Figure 6 is a flow chart showing the operation of the conventional caption processing apparatus. Initially, in step S601, the pixel data of the subtitle image and its display properties including horizontal and vertical addresses, the width and height in the pixels are input to the subtitle processing device 51 and stored in the buffer. Then, in step S602, the TV user presses the button on the remote controller control portion 511 in Fig. 5 to enlarge or reduce the size of the subtitle. If the user selects the size of the enlarged subtitle, then in step S603, one pixel is copied into m*n pixels to form a rectangle. Then, in step S605, the image reproduction portion 513 acts to detect whether the width of the new subtitle image generated from step S603 is wider than the display width. If not, then to step S608, the position adjusting portion 516 acts to recalculate the horizontal address and place the subtitle image at the center of the display. In step S605, if the condition is satisfied, then go to step S606, and the image reproducing portion 513 acts to calculate the cut point and cut the new subtitle image into two images or more. Moreover, the horizontal addresses of these images are calculated to be placed at the center of the display; the distance in the pixels between these images is a constant. In step S602, if the user presses the button of the illustrated control portion 511 to select to reduce the subtitle, the subtitle image has two colors, a foreground (text) and a background (text background) color. Then, in step 1334588 S604, the background color search portion 514 searches for an image whose color is a color in a pixel compared to another word. In step S6, the m*n pixels in which the pixel appears in a rectangle of the image are reduced. When the pixel-like portion 515 makes a pixel having a foreground color, its == color. The test step S 6 0 8 is used to position the image display positions so that they are center-aligned. The new subtitles of the nose are displayed in step S602. If the user does not want to change to the step lion, the subtitle image will be displayed on the display device 53 according to the nature of the display such as the word. Ma Yi 52 specified, however, the above-mentioned subtitle processing device is enlarged in such a manner that all fonts are enlarged or reduced together with a computer, and a type of device such as a personal digital assistant (10), etc., because the screen ^==the content displayed on the palm is too small, And not all of the characters are complex - the screen characters (such as Chinese characters with more strokes), if not enlarged, there is no: clear Ϊ 5 full description of the questions raised, hoping to be in the small screen The money is enlarged to achieve clear and visible needs. ^I have been engaged in research and many practical experiences for many years, and have been researched and designed by many parties. ^: Discussing, according to the present invention, the method and basis for magnifying and displaying the shape of Fangmuwangyi. In view of the above problems, the main object of the present invention is to provide a method for enlarging a displayed word, which is to use a vector word to enlarge according to a certain ratio, and to display an unclear character by too many strokes.
