A small barcode decoding device

Abstract

The invention is a small barcode decoding device, the shell is set in a flat shape, and the thickness is reduced. The housing is provided with an illumination window that deflects toward the lens opening, which can guide the illumination light source to the front of the imaging component, which is beneficial to the imaging of the barcode in the barcode image, and can meet the barcode image acquisition without setting a separate illumination lens lighting needs, thereby reducing the size of the illuminated area. The lens opening is also equipped with a stepped circular concave, which can resist the diffuse reflection of more stray light, making the image more pure when the lens collects barcode images. The main control chip itself has the ability to decode barcodes without calling a separate stored decoding program, which improves the decoding speed of barcodes and reduces the amount of device design, thereby reducing the area of ​​the circuit board and ultimately reducing power consumption.

Description

technical field [0001] The invention relates to an image acquisition device for barcode reading, in particular to a small barcode decoding device. Background technique [0002] With the mobile payment scenarios of Cloud QuickPass, WeChat Pay, and Alipay spreading rapidly, the existing cashless payment has gradually shifted from card payment to barcode (mainly QR code and CODE128 code) payment. Existing card payment devices are also required to be compatible with barcode reading to apply the payment method of barcode payment. With the popularization of smart operating systems such as Android and the lowering of the threshold for hardware operation, and the popularization of 4G\5G wireless networks, payment devices are also developing towards high-speed and intelligent networks. [0003] Due to the fact that intelligent payment devices have better computing power and suitable storage space for software programs, and under the current trend of miniaturization and thinning, sma...

AI Technical Summary

Problems solved by technology

The existing barcode reading module is relatively large in size, and there are many components in the hardware circuit design. For example, the main control chip using the MIPI architecture decodes by calling the decoding program of the external memory. Due to the energy consumption of the main control chip, lead to high power consumption

Lighting and aiming designs usually pursue high brightness and personalized aiming indicators, resulting in high power consumption of such light source devices, which are not suitable for thin and light smart devices
