QR碼讀取筆對於QR碼的使用提供了一個非常方便的工具。未來將致力於發展QR碼在各領域的應用，使QR碼能廣範使用在我們日常生活中，以提升生活的便利性。 The QR code is developing from the one digit barcode. Because, the wide ranges of the barcode usage in our daily life and technology’s improvement, the traditional one dimension barcode system with only 15 digits of numbers or words data are not enough to be use. So to overcome this issue, the two dimension barcode is developed and the QR code is one of the two dimension barcode system with the large data with the small printing size. QR code reading pen is a solution of a mobile device to decode the QC code and show the data in the QR code. This will make the QR code become more easy and convenient to be use.
This thesis is mainly focus on the designing of QR code reading pen. The QR code reading pen is the device can capture the QR code image and decode it. This device is mainly use the Windbond 32 bites RISC W99802G processor to design the QR code’s decoder and audio processor. Through the sensor point on the QR code images, the Windbond 32 bites ARM9 CPU will decode the QR code. The structure of QR code reading pen can be dividing into three parts. The first part is the image sensor of the QR codes to capture the QR code images. Second part of the QR code reading pen will start to image process and decode by the W99802G. The final part is to display the data which W99802G has decoded on the LCM screen.
