Portable terminal device, program for reading information, and recording medium having the same recorded thereon

A portable terminal device comprising:

• an imaging unit that images an object;
• a display unit that displays an image produced by said imaging unit;
• a code recognizing unit that recognizes a code of said image;
• a code recognition instructing unit that activates said code recognizing unit in response to a user instruction;
• and
• an imaging procedure switching unit that switches the imaging unit from an imaging mode to a code mode,
• wherein said imaging unit is disposed on a back side of a main body, and said display unit is disposed on a front side of said main body,
• wherein after the imaging unit has been switched to the code mode by said imaging procedure switching unit and before said code recognizing unit is activated, said image is displayed on said display unit continuously with the display magnification changed in accordance with the type of code that can be read,
• and wherein, after said code recognizing unit is activated, code recognition is performed continuously while said image is displayed on said display unit at a frame rate required by said code recognizing unit, and, once code recognition is successfully completed, the result of code recognition is displayed on said display unit instead of said image.

A portable terminal device comprising:

• an imaging unit that images an object;
• a display unit that displays an image produced by said imaging unit;
• a code recognizing unit that recognizes a code of said imaged object;
• and
• an imaging procedure switching unit that switches the imaging unit to a code mode in response to a user operation,
• wherein said imaging unit is disposed on a back side of a main body, and said display unit is disposed on a front side of said main body,
• wherein, after the imaging unit is switched to the code mode by said imaging procedure switching unit, said image is displayed on said display unit continuously at a frame rate required by said code recognizing unit while the display magnification is changed in accordance with the type of code that can be read,
• and wherein, once code recognition is successfully completed, the result of code recognition is displayed on said display unit instead of said image.

A method of imaging an object using a portable terminal device comprising the steps of:

• producing and displaying an image of the object on a display unit;
• switching the imaged object to a code;
• increasing the magnification of the image on the display unit;
• and
• performing code recognition continuously while continuously displaying the image on the display unit at a frame rate required for code recognition.

• producing and displaying an image of the object on a display unit;
• switching the image to a code;
• increasing the magnification of the image on the display unit;
• and
• performing code recognition continuously while continuously displaying the image on the display unit at a frame rate required for code recognition.

A method of imaging an object using a portable terminal device having an imaging unit that images an object, a display unit that displays an image produced by said imaging unit, a code recognizing unit that recognizes a code of said imaged object, an imaging procedure switching unit that switches the imaging unit from an object mode to a code mode in response to a user operation, wherein said imaging unit is disposed on a back side of a main body, and said display unit is disposed on a front side of said main body, comprising the steps of:

• switching the imaging unit to the code mode;
• changing the display magnification in accordance with the type of code that can be read,
• displaying the image on said display unit continuously at a frame rate required by said code recognizing unit;
• and, once code recognition is successfully completed, displaying the result of code recognition on said display unit instead of said image.

A portable terminal device comprising:

• an imaging unit that images an object;
• an imaging procedure switching unit that switches an imaged object to a code;
• a display unit that displays an image produced by said imaging unit;
• a code recognizing unit that recognizes a code of said imaged object;
• a control unit that causes, once the imaged object is switched to a code by said imaging procedure switching unit, image information to be displayed on said display unit with an increased magnification,
• a frame rate control unit that sets the frame rate of display prior to the start of code reading to be higher than the frame rate after the start of code reading and continuously code recognizing.

A method of imaging an object using a portable terminal device comprising the steps of:

• producing and displaying an image of the object on a display unit a first frame rate;
• switching the imaged object to a code;
• increasing the magnification of the image on the display unit;
• and
• setting the frame rate of display to a second frame rate lower than the first frame rate.
