<p><P>PROBLEM TO BE SOLVED: To enable a command acquired from a code symbol to be set with a desired parameter without using an input device. <P>SOLUTION: A code reader 1 detects a QR code (R) 21 by performing image recognition processing on image data of a subject 2 imaged by a camera 101 to display the QR code 21 on a display 102 and also acquire a command from the QR code 21. Also, based on a movement of the QR code 21 detected from a series of image data of the subject 2 imaged by the camera 101, the code reader 1 specifies a parameter, and sets the parameter in the acquired command. A user can set a desired parameter in the command acquired from the QR code 21 by holding the subject 2 recording the QR code 21 on the code reader 1 and performing a predetermined movement of the subject 2, without using an input device. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
