MULTIPLE RESOLUTION READABLE COLOR ARRAY

摘要

A multiple resolution readable color array (60) printed for labeling or displayed electronically achieves readable data at multiple optical resolutions. The array has a hierarchy of cells, where cells at a lower level of resolution (70) include spatially adjacent smaller cells at a higher level of resolution (80). Colors are encoded in redundant cells (2, 4, 5, 6) within the hierarchy so that overall color assigned to a lower resolution cell depends on the colors encoded in the included data cells at a higher resolution.
