  • Patent number: 4576904
    Abstract: More effective camouflage patterns are generated by use of certain known tographic and photooptical contrasting procedures to obtain more desirable positive high contrast images representative of the natural background areas in which military equipment is intended to operate. Generating and using such camouflage patterns constitute a unique and novel use of such images which have predetermined color tones or values assigned to varying degrees of light, intermediate and dark contrast areas. The patterns may be applied onto the equipment in any of several conventionally known manners, thereby enabling otherwise artistically unskilled field soldiers to more effectively camouflage their equipment.
