Multiple resolution readable color array
摘要:
A multiple resolution readable color array 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 include spatially adjacent smaller cells at a higher level of resolution. Colors are encoded in redundant cells 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.
