Converted digital colour image with improved colour distinction for colour-blinds

摘要

A method of converting a digital colour image to a digital colour image with improved colour distinction, and more particularly a method of this kind suitable for improving colour distinction in a colour image for an observer suffering from a type of colour-blindness. The method is using an algorithm comprising the steps of:defining a number of main colour values of the digital colour image;converting the main colour values to converted main colour values such that the converted main colour values are perceived mainly distinguishable from each other by a colour-blind observer; andrendering the digital colour image with converted main colour values.
