Abstract
In an information reader, a first relationship information, which defines the two-dimensional area of a first information code (e.g., the position coordinates of the four corner points), is detected from a first information code image. The first information code is subjected to reading information, based on the detected first relationship information. Parameters of a learning model are then adjusted based on training data including multiple successful cases of a reading process using the first relationship information. A second information code image captured by a camera is inputted to the learning model. A second relationship information, which is an estimated value of the information that defines the two-dimensional region of the second information code, is obtained from the learning model. The information recorded in the second information code is read based on the acquired second relationship information, thus reading results being outputted.
