ABSTRACT:
An apparatus and method for efficiently displaying information for an object two-dimensionally. A two-dimensional pattern displayed in a two-dimensional tag comprises a first region consisting of a locational reference region that is square and located in the center of the first region for identifying the location and an identification region that surrounds the locational reference region and is a single data cell, a second region in which a black pattern and a white pattern appear alternately for identifying the starting location for reading information, and a third region for displaying coded information about the object. Detection of the square region in the first region allows detection of the location of the two-dimensional tag in which the two-dimensional pattern is displayed, while detection of the data cell of the second region in which black and white appear alternately allows detection and correction of the location of the two-dimensional tag. This constitution enables effective use of the outer circumference in which much information can be displayed.
