CODE READER DEVICE WHICH DISPLAYS A CODE EXTRACTING AREA OF A SUBJECT IMAGE TO HAVE A SIZE BASED ON A SPECIFIED DISPLAY SIZE OF THE SUBJECT IMAGE, AND RECORDING MEDIUM THEREFOR

摘要

A code reader device, prior to extracting a code from an image captured by a camera, receives an image size data, and according to the received image size, displays the captured image on the display device so that a code extracting target area is discriminated from a remaining area. A layout of the captured image on a display screen becomes flexible, so that usability for reading the code can be improved.
