Digital camouflage is a type of camouflage pattern combining micro- and macro patterns, often though not necessarily with a pixellated look created with computer assistance. The function is to provide military camouflage over a range of distances, or equivalently over a range of scales, in the manner of fractals. Not all multiscale patterns are pixellated, and not all pixellated patterns work at different scales, so being pixelated does not of itself guarantee improved performance. The root of the modern digital camouflage patterns can be traced back to 1930s experiments in Europe for the German and Soviet armies. Modern digital patterns date to the 1970s, first with Canadian development of CADPAT and then with U.S. Army work led by Timothy O'Neill which created MARPAT. ==Principles== Digital camouflage is based on three principles: * ''Bi- or multi scale patterns'' - adding high spatial frequency texture components for concealment at closer ranges * ''Dithering'' - producing intermediate colours where two fields of colour meet * ''Edge effect'' - modifying visual processing of edges 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Digital camouflage」の詳細全文を読む スポンサード リンク
