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

An information processing method for an information processing apparatus for reading a code included in an image, comprising the steps of:

• acquiring image data of a captured image obtained by an imaging portion, the 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;
• recognizing the predetermined fixed area code of the fixed area by analyzing the captured image;
• setting a default value of the variable area code based on the recognized predetermined fixed area code;
• recognizing the variable area code of the code included in the captured image by analyzing the captured image;
• comparing the recognized variable area code with the set default value to determine a difference between the variable area code and the default value;
• and
• designating a command to be executed based on the determined difference.

• recognizing the predetermined fixed area code of the fixed area by analyzing the captured image;
• setting a default value of the variable area code based on the recognized predetermined fixed area code;
• recognizing the variable area code of the code included in the captured image by analyzing the captured image;
• comparing the recognized variable area code with the set default value to determine a difference between the variable area code and the default value;
• and
