According to the present invention, still pictures can be compressed by restructuring the still pictures with different number of colors depending on each still picture. The method of compressing still pictures according to the present invention comprises: obtaining (R, G, B) values of every pixel in the whole still picture; designating (R, G, B) values mainly included in the still picture as representative (R, G, B) values of the still picture, the number of the representative (R, G, B) values being determined depending on each still picture; and giving index values to the representative (R, G, B) values and storing the representative (R, G, B) values in palette.</p> |
