System and method for reading an information code

An information code reading system comprising:

• a mobile terminal comprising:
• a terminal sensor configured to detect a tilt state of the mobile terminal relative to a horizontal plane;
• a terminal processor programmed to generate an information code such that the tilt state of the mobile terminal, detected by the terminal sensor, and predetermined information are recorded in the information code;
• and
• a screen configured to display the information code;
• and
• a reader comprising:
• an imager provided with a reading surface and configured to image the information code held over the reading surface;
• a memory, a tilt state of the reading surface relative to the horizontal plane being previously stored in the memory;
• and
• a reader processor programmed to:
• read both the tilt state of the mobile terminal and the predetermined information from the information code imaged by the imager;
• determine whether or not both the tilt state stored in the memory and the tilt state of the mobile terminal are a same tilt state;
• and
• perform processing based on the predetermined information when it is determined that the tilt state of the reading surface and the tilt state of the mobile terminal are the same tilt state.

• a reader processor programmed to:
• read both the tilt state of the mobile terminal and the predetermined information from the information code imaged by the imager;
• estimate the tilt state of the mobile terminal based on distortion of the information code imaged by the imager;
• determine whether or not the estimated tilt state of the mobile terminal and the tilt state of the mobile terminal read by the reader are a same tilt state when the reader reads the information code;
• and
• perform processing which uses the predetermined information when it is determined that the estimated tilt state of the mobile terminal and the tilt state of the mobile terminal read by the reader are the same tilt state.

A reader which acquires predetermined information by optically reading an information code displayed on a screen of a mobile terminal, the mobile terminal being configured to detect, as a terminal environmental state, at least one of a state of the mobile terminal or a state around the mobile terminal;

• to generate the information code, the detected terminal environmental state, and the predetermined information being recorded in the information code;
• and to display the generated information code, the reader comprising:
• an imager provided with a reading surface and configured to image the information code held over the reading surface;
• a reader sensor configured to detect a reading surface environmental state corresponding to the terminal environmental state, the reading surface environmental state being at least one of the state of the reading surface or the state around the reading surface;
• and
• a reader processor programmed to:
• read both the terminal environmental state and the predetermined information from the information code imaged by the imager;
• determine whether or not both the reading surface environmental state and the terminal environmental state are the same environmental state when the reader reads the information code;
• and
• perform processing based on the predetermined information read by the reader when it is determined that the reading surface environmental state and the terminal environmental state are the same environmental state.
