Abstract:
1. An encoded colorgram, comprising: a data field decorated with a predetermined physical pattern of colored cells, wherein the variety of colors is limited to a finite set of colors in discrete steps, and configured for imaging by a digital camera of all the colored cells at once, and wherein the choice of colors of each colored cell and its location within the predetermined physical pattern is interpreted as the encoding of data; a subfield of calibrating colored cells disposed in an standardized place in the data field and a standardized choice of colors of each colored cell from the finite set of colors in discrete steps and a standardized location within the subfield; and data that is visually encoded into the data field as a particular step in one of the color cells in the finite set and in their respective locations within the predetermined physical pattern; wherein, the subfield of calibrating colored cells provides color decoding information on which discrete color step is represented by each of the colored cells in the data field.
