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 [LR,] resides in a first of said storage banks [420R] and such that low-resolution image-data defining a second low-resolution row [LR,], adjacent to the first low-resolution row [LR,], resides in a second of said storage banks [420L]; extracting first through Nth low-resolution pixel signals [S,-S,] from the memory [420], said signals representing values of low-resolution pixels in the adjacent first and second low-resolution rows [LR,,LR,] of the low-resolution image-data [125]; and producing a high-resolution pixel signal [Hpx] from said first through Nth low-resolution pixel signals [S,-S,] in accordance with a distance-weighted algorithm.
