Abstract

The present application relates to a method for optimising the choice of colours, included in the colour palette, when presenting a picture with fewer colours than those available in an original form of the picture. All colours are present as a combination of primary colours, for instance red, green and blue (RGB), and one generates a multidimensional histogram with said primary colours along the axes, in which the colours of all pixels are inserted. Then the entire histogram is considered as a colour block and the operations involving trimming of colour blocks and division of colour blocks are carried out until a predetermined number of blocks is available, whereupon each block is allowed to be represented by a colour which is representative of the block. Finally, the picture is presented with the thus-selected colours.
