摘要： A character display apparatus searches through a cache means for vector font data which match character attributes of a character to be displayed to acquire the vector font data, and, when no vector font data which match the character attributes of the character to be displayed exist in the cache means, acquires the vector font data from a large-volume storage means. If there exists no corresponding luminance image data in the cache means, the character display apparatus acquires luminance image data generated from the vector font data. If there exists no corresponding display image in the cache means, the character display apparatus acquires display character image data generated from the luminance image data. The character display apparatus displays the display image which is thus acquired and which matches the character attributes of the character to be displayed on a display device.
摘要翻译：字符显示装置通过高速缓存装置搜索与要显示的字符的字符属性匹配的矢量字体数据以获取矢量字体数据，并且当没有与要显示的字符的字符属性匹配的矢量字体数据存在于高速缓存装置从大容量存储装置获取矢量字体数据。如果高速缓存装置中没有对应的亮度图像数据，则字符显示装置获取从矢量字体数据生成的亮度图像数据。如果高速缓存装置中没有相应的显示图像，则字符显示装置获取从亮度图像数据生成的显示字符图像数据。字符显示装置显示如此获取的显示图像，并且与显示装置上要显示的字符的字符属性相匹配。
