发明名称 Method for displaying an image including characters and a background
摘要 In a method for displaying an image, the image is divided into a first image area which includes characters, the border of which is overlapping a part of a color background, and a second image area which includes the other part of the background. The method includes the steps of setting data of pixels of the image using n bits in a multi-purpose area of an image memory, in a manner that, in setting data of pixels in the first image area, some of the n bits are used for color information of the background present at the border of the characters and the others are used for data of the characters. Further, in setting data for pixels in the second image area, all of the n bits are used for color information of the background, except that of the part underlying the border of the characters. The method further includes the steps of setting a flag in another area of the image memory, the flag indicating to which of the first and second image area each of the pixels of the image belongs; synthesizing color information of the background and that of the characters based on the image data and the flag stored in the image memory so that colors of the characters at the border thereof are mixed with colors of the background so as to have neutral tints; and displaying the image, obtained through the synthesis, on a display unit.
