Information processing apparatus and method

摘要

An information processing apparatus includes an image data acquisition unit, a fixed area code recognition unit, a variable area code default value setting unit, a variable area code recognition unit and a command designation unit. The 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 is formed by a combination of a plurality of codes. The fixed area code recognition unit analyzes the captured image to recognize the predetermined fixed area code of the fixed area. The variable area code default value setting unit sets the default value of the variable area code based on the predetermined fixed area code. The variable area code recognition unit analyzes the captured image to recognize the variable area code. The comparator compares the variable area code with the default value to determine the difference therebetween. The command designation unit designates a command to be executed based on the difference between the variable area code and the default value. Accordingly, a user interface can be created and operated inexpensively which allows a user to input a greater variety of operational instructions.
