International ClassG09G 001/06AbstractThe 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 having independently addressable storage banks; storing the low-resolution image-data in the memory such that low-resolution image-data defining a first low-resolution row resides in a first of said storage banks and such that low-resolution image-data defining a second low-resolution row, adjacent to the first low-resolution row, resides in a second of said storage banks; extracting first through Nth low-resolution pixel signals from the memory, said signals representing values of low-resolution pixels in the adjacent first and second low-resolution rows of the low-resolution image-data; and producing a high-resolution pixel signal from said first through Nth low-resolution pixel signals in accordance with a distance-weighted algorithm.Other References
