Benefits of technology
The present invention provides a code reader device that can extract a code from an image and decode it. The device includes an image size specifying unit that specifies the display size of the image before extracting the code. A display unit then displays the image with the specified display size, making the code extracting area distinct from the remaining area. This helps to improve the accuracy and efficiency of code extraction.
Problems solved by technology
However, with the camera-equipped mobile phone, it is difficult to arrange a layout flexibly on a display screen such that the captured code is displayed with an enlarged size, and an area indicating the decoded information or operation information is displayed with a reduced size.
In other words, there is a problem that a usability of this kind of camera is not satisfactory.

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.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2005-310968, filed Oct. 26, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a code reader device for reading a code such as a bar code or a two-dimensional code, and a recording medium. [0004] 2. Description of the Related Art [0005] Conventionally, a code reader device for reading a code, such as a bar code or a two-dimensional code, captures the code by an image sensor such as a charge coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS), displays the captured image with a frame on a display screen such as a liquid crystal display (LCD), detects the code within the frame, and decodes the detected code. In order for the code reader device to properly read the code, a user adjusts a sho...
