  • Patent number: 6226401
    Abstract: An image recognition system for recognizing a target having a color and a pattern includes a plurality of active eyes for recognizing a target. Each active eye is an information processing unit formed in a closed frame defined on a display screen, and each active eye is movable on the display screen, wherein each active eye moves until a color within the closed frame of the active eye is the color of the target in a memory, wherein plural active eyes are located at a boundary between the target and the background on the display screen, thereby forming a colony having a shape. When the shape of the colony matches the pattern of the target in the memory, the target is identified. The time of each processing cycle is very short, and thus, the movement of the object can be traced without a time lag.
