Desktop bar code reading device for mobile payment

Abstract

According to the desktop type bar code reading device for mobile payment, the light guide cover which uniformly diffuses the illumination light supplementing light source outwards is matched with the uniformly arranged lamp beads to serve as the illumination light supplementing light source, so that light generated by the illumination light supplementing light source can uniformly abut against the surface of a bar code to be shot. According to the method, two illumination light supplement control modes are set, under the first illumination light supplement control mode, the picture brightness can be rapidly adjusted to a proper range through fixed exposure parameters so as to adapt to reading of mobile phone payment codes with different screen brightness, and the mobile adaptability and the decoding success rate are improved. The light supplement with the set fixed time length enables the user to look continuous illumination and light supplement, and the illumination is soft, thereby facilitating the recognition and reading of the screen display bar code. Under the second lighting supplementary lighting control mode, fixed exposure parameters are adopted in the first two frames to adapt to reading of screen codes; other frames adopt an automatic adjustment exposure mode of the image sensor to adapt to reading of paper barcodes.

Description

technical field [0001] The invention relates to a code scanning device for barcode reading, in particular to a desktop barcode reading device for mobile payment. Background technique [0002] With the rapid iterative development of mobile networks and the explosion of mobile Internet users, more and more application scenarios based on mobile terminals are emerging. Barcodes have also been derived from the earliest logistics inventory and commodity retail to be used on mobile payment carriers. Mobile payment has become a popular payment method for the people. A mobile phone can realize payment in various consumption scenarios, whether it is grocery shopping at a vegetable market, ticket purchase at a station, or shopping at a convenience store. [0003] With the popularization of mobile payment, new reading requirements are put forward for barcode reading equipment. The barcode on the traditional serial express delivery order number, etc. Because it is a non-luminous mater...

AI Technical Summary

Problems solved by technology

For the barcode displayed on the screen, because the screen is self-illuminating and the screen is highly reflective, conventional barcode equipment will reflect the stray light of the external environment into the image sensor in the barcode reading equipment due to the high reflectivity of the screen surface. , causing the final image to be blurred and unable to accurately restore the barcode image

However, the existing barcode reading equipment needs to undertake the reading tasks of reading screen barcodes and printed barcodes at the same time.

If only one lighting supplementary light mode is used, the requirements of these two types of reading supplementary light scenarios cannot be met, and the image sensor cannot obtain sufficient or excessive reflection of the barcode

Difficulty in reading and reduced reading efficiency
