Abstract:
A display device comprising:a display section for displaying a window frame of a standard pixel number; a data acquiring section for acquiring image data of a given pixel number from any of various applications; an image data storing section for storing therein the image data; a pixel number determining section for determining the pixel number on the basis of attribution data attached to the image data; a pixel number judgment section for judging whether or not the pixel number is smaller than the standard pixel number preliminarily stored in a standard pixel number storing section; a data expanding section for expanding the image data to increase the pixel number of the image data to the standard pixel number, if the pixel number is smaller than the standard pixel number; a display control section for controlling the display section to display the expanded image data in the window frame of the standard pixel number so that the window frame which contains the expanded image data can coexist with a window frame which contains image data of the standard pixel number on the display section; a character detecting section for detecting font data and a character code in the image data in response to a judgment made by the pixel number judgment section that the pixel number of the image data stored in the image data storing section is smaller than the standard pixel number; a font size determining section for determining a font size for the character code on the basis of the attribution data attached to the image data; a font data storing section which stores therein font data of various font sizes for character codes; and a font replacing section for retrieving, from the font data storing section, font data of a font size which corresponds to a scaling factor employed for the image data expansion by the data expanding section, and replacing the font data of the image data with the retrieved font data.
