Abstract: An information processing apparatus includes the following elements. An image data acquisition unit acquires image data of a captured image including a code having a fixed area in which a predetermined fixed area code is formed and a variable area in which a variable area code formed by a combination of a plurality of codes is formed. A fixed area code recognition unit analyzes the captured image to recognize the predetermined fixed area code of the fixed area. A variable area code default value setting unit sets the default value of the variable area code based on the predetermined fixed area code. A variable area code recognition unit analyzes the captured image to recognize the variable area code. A comparator compares the variable area code with the default value to determine the difference therebetween. A command designation unit designates a command to be executed based on the difference.

Abstract: An information processing system is provided, which is capable of easily changing a two-dimensional bar code at a low cost, and further capable of detecting the change and creating a computer graphics image corresponding to the change. An object (10) to be imaged has a display section (11) thereon for displaying and making changeable part of a two-dimensional bar code (10a) arranged on the object (10). An information processing apparatus (20) detects the two-dimensional bar code (10a) from a captured image obtained by imaging the object, and creates and outputs a computer graphics image corresponding to the two-dimensional bar code (10a). If the object (10) changes the two-dimensional bar code (10a), the information processing apparatus (20) creates and outputs a computer graphics image corresponding to the change.
