发明名称 Localization device for optically-readable code or text uses localization pattern with at least four 2-dimensional elements of 2 different types
摘要 The localization device has at least one localization pattern (2) placed over the code or text, each localization pattern having a 2-dimensional arrangement of at least four 2-dimensional elements (3) of 2 different types, placed in a regular square or hexagonal pattern so that 2 elements of similar type are not next to one another along a common line. An Independent claim for automatically-readable text is also included.
