Abstract: The invention provides a method and apparatus for enhancing apparent image resolution by way of multi-line interpolation. A method for enhancing the resolution of low-resolution image-data includes the steps of: providing a memory (420) having independently addressable storage banks (420L, 420R); storing the low-resolution image-data (125) in the memory (420) such that low-resolution image-data defining a first low-resolution row (LR0) resides in a first of said storage banks (420R) and such that low-resolution image-data defining a second low-resolution row (LR1), adjacent to the first low-resolution row (LR0), resides in a second of said storage banks (420L); extracting first through Nth low-resolution pixel signals (S1-S3) from the memory (420), said signals representing values of low-resolution pixels in the adjacent first and second low-resolution rows (LR0, LR1) of the low-resolution image-data (125); and producing a high-resolution pixel signal (Hpx) from said first through Nth low-resolution pixel signals (S1-S3) in accordance with a distance-weighted algorithm.

Abstract: An apparatus and method for updating a color look up table (200) and expanding video data for use in various applications such as a multimedia computer. The color look up table updating scheme permits selective updating of one entry in the table or up to all of the entries in the table. Updating of the color look up table (200) is performed during the horizontal blanking period. The table may be comprised of two buffers, and a combined output of these two buffers (125, 126) further enhances a multiplicity of colors available to a user.
