Abstract

This specification provides a control method, device, device and code scanning device for a positioning light of a code scanning device. The method can monitor the level signal of the strobe pulse pin of the camera device in the code scanning device. When the foot reaches a high level, the positioning light is turned off, which reduces the energy consumption caused by the positioning light under the premise that the camera equipment completes the positioning function. Affects the scanning effect of graphic code images.

Description

technical field [0001] This specification belongs to the field of computer technology, and in particular relates to a control method, device, device and code scanning device for a positioning light of a code scanning device. Background technique [0002] With the popularization of graphic code technology and mobile payment, one-dimensional code, two-dimensional code and other graphic code recognition have been gradually applied to various industries in society, and code scanning equipment has also been widely used. At present, the mainstream technology of graphic code recognition is to perform optical imaging through a CMOS (Complementary Metal Oxide Semiconductor) camera module, and then perform decoding by a back-end main control IC (Integrated Circuit Chip). [0003] Generally, the scanning device includes a positioning light, which is mainly used to locate the graphic code, so that the scanning device can completely capture the image of the graphic code area, and then de...
