Problems solved by technology

The positioning spot of the rectangular frame generated by the light-emitting diode through the shading object or the shading plate plays the role of positioning, which can improve the user's scanning experience, but the positioning spot obtained in this way is on the outer boundary of the camera scanning area and cannot scan the camera. The area has the effect of filling light and will affect the camera's photo effect

Abstract

A two-dimensional code scanner sharing a light supplementation lamp and an alignment lamp, comprising a camera, a light-emitting diode and a lampshade, wherein the light-emitting diode is located in the lampshade, and the top of the lampshade is provided with a rectangular through hole; and the light-emitting diode is located beside the camera, and the illumination range of the light-emitting diode is within a photographing region coverage of the camera. Light from the light-emitting diode not only can play a role of positioning for the photographing of a camera, but also can play a role of light supplementation.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code scanners, in particular to a two-dimensional code scanner that shares a supplementary light and an alignment light. Background technique [0002] In the current QR code scanner, a supplementary light or an alignment light is installed on the side of the camera. The function of the supplementary light is that the camera has insufficient light when taking pictures, and the alignment light is used for quick alignment when scanning codes. It can improve the user's scanning experience. At present, there is no situation where the fill light and the alignment light are shared. [0003] The Chinese invention patent with the publication number CN103679113A discloses a method and system for positioning and focusing when an OTP device scans a two-dimensional code. A positioning light generating device for generating a positioning spot is provided in the OTP device, and the positioning light gen...
