Method of performing an assay, apparatus therefor, and a method of manufacturing and apparatus

Abstract

The invention relates to a method of transforming a colour image, wherein for each separate pixel a measured level of lightness, a measured chroma and a measured colour is determined, followed by a predetermined adjustment in the three-dimensional level of lightness, chroma and colour, wherein a. for each separate pixel a direction of adjustment is determined by selection of a three-dimensional adjustment level for lightness, chroma and colour change, b. and in that at the three-dimensional adjustment level selected the maximum available lightness change is determined, whereafter c. for each separate pixel the measured lightness level, the measured chroma and the measured colour is changed in the direction of the selected three-dimensional adjustment level in concurrence with a predetermined function, which at most amounts to the maximum available lightness change at the selected three-dimensional adjustment level.Electrical Engineering, Mathematics and Computer Scienc
