Abstract:
1. A method for up-scaling a color image prior to performing subsequent processing on said color image, the up-scaling method comprising the steps of: a) converting the color image into multiple image layers distinguishable from each other; b) up-scaling at least one of said multiple image layers; wherein step b) comprises the steps of: c) taking among said image layers a predetermined selection of at least one first image layer for up-scaling by means of a first up-scaling method, said first up-scaling method having a predetermined quality; d) up-scaling only said at least one first image layer by means of said first up-scaling method, thereby forming at least one up-scaled first image layer; e) taking among said image layers a selection of at least one second image layer f) up-scaling the at least one second image layer by means of a second up-scaling method, thereby forming at least one up-scaled second image layer, said second up-scaling method having a lesser quality than said first up-scaling method; g) recombining said up-scaled first and second image layers into a destination color image, and in that said predetermined selection and said predetermined quality are chosen for facilitating said subsequent processing.
