Information processing apparatus and method, input device and method, program, and information processing system

摘要

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.
