Barcode recognition engine and power consumption reduction control method therefor

Abstract

The embodiment of the invention discloses a barcode recognition engine and a power consumption reduction control method therefor. The barcode recognition engine comprises an optical imaging unit, a light supplementing unit, an aiming unit, a decoding unit, and an engine single-chip microcomputer. When the decoding unit is triggered for decoding, the optical imaging unit collects an optical signal,converts the optical signal into image data and transmits the image data to the decoding unit for decoding. The optical imaging unit controls the power supply state of the light supplementing unit according to a frame period signal generated in the optical imaging unit and a power control signal outputted by the engine single-chip microcomputer. The optical imaging unit controls the light supplementing unit to start light supplementing in the exposure time period of the frame period signal. The light supplementing unit carries out the light supplementing enhancement for the optical imaging unit when the light supplementing unit is turned on, and the aiming unit is used for aiming instruction. The light supplementing time duration is synchronously adjusted through the exposure time, and achieves the periodic and regular switching of light supplementing, thereby causing no impact on the imaging quality while achieving the low power consumption and low temperature, and enabling the imaging to be more stable.

Description

technical field [0001] The invention relates to the technical field of barcode identification, in particular to a barcode identification engine and a control method for reducing power consumption thereof. Background technique [0002] With the popularity of barcode applications and mobile payments, two-dimensional code recognition has gradually been applied to various industries in society. At present, two-dimensional code recognition usually adopts the image-based reading method, and the mainstream technology is through CCD (charge-coupled device, a semiconductor device) / CMOS (complementary metal-oxide semiconductor, a voltage-controlled amplification device). The lens is used for optical imaging, and then the decoding part of the back end is used for image recognition. The original image quality is crucial to the efficiency of decoding. In order to obtain better image quality, additional light is usually used to improve the obtained image quality. Especially in low-light...
