Digital information carrier

A digital information carrier characterized by:

• containing cluster information carrier(s) constituted by at least two of the image objects;
• said cluster information carrier(s) having
• a condition, correlated to a relative relationship between said at least two image objects forming the constituent elements, for determining whether image objects constitute a cluster information carrier, and
• bit data correlated to said cluster information carrier(s) as units.

A digital information carrier characterized in that:

• configuration of a logical block formed by unifying a plurality of unit information carriers being the minimum units for decoding bit data from a digital information carrier is enabled;
• an item of information is assigned to an array formed by unifying any number of constituent elements of said logical block concerned;
• and
• configuration of a new logical block by replacing at least one of the constituent elements of said logical block with a unit information carrier neighboring said logical block is enabled.

A digital information carrier characterized in:

• containing a bit matrix V formed by arranging, in matrix form, array elements bm (m=0 to n−1) of a reference-bit array B having a predetermined array length n, wherein bit data is correlated to the bit matrix V;
• that two matrix elements v(i, j) and v(i+1, j) neighboring one (i-axis) of the two array axes of the bit matrix V satisfy
• v(i, j)=bm
• v(i+1, j)=bm+1;
• and
• that two matrix elements v(i, j) and v(i, j+1) neighboring the other array axis (j-axis) of the bit matrix V satisfy, letting the amount by which the array elements bm are offset toward the j-axis be a,
• v(i, j)=bm
