<p>A method and apparatus for improving the quality of a color-to-gray scale conversion is disclosed. A table is generated providing a visually correct conversion of all possible background/foreground colors. This table is then stored. In operation, after the attribute byte describing the foreground and background colors is retrieved from memory (13), it is used to access the stored conversion table, wherein its gray scale equivalent is stored. The stored equivalent is then used to generate the gray scale LCD display. In other embodiments, multiple copies of the table are stored, making multi-frame operations very efficient in operations.</p> |
