The embodiment of the present invention discloses a barcode recognition engine and its control method for reducing power consumption. The barcode recognition engine includes an optical imaging unit, a supplementary light unit, an aiming unit, a decoding unit and an engine single-chip computer; when the decoding unit triggers decoding , the optical imaging unit collects light signals and converts them into image data and transmits them to the decoding unit for decoding; the optical imaging unit controls the power supply state of the supplementary light unit according to the frame period signal generated inside it and the power supply control signal output by the engine microcontroller; the optical imaging unit The unit controls the supplementary light unit to turn on the supplementary light at the exposure time of the frame period signal, and controls the supplementary light unit to turn off at the sampling time of the frame period signal; when the supplementary light unit is turned on, the optical imaging unit is used for supplementary light enhancement, and the aiming unit is used for aiming instruct. The duration of supplementary light is adjusted synchronously through the exposure time, and the supplementary light is switched on and off periodically to achieve low power consumption and low temperature without affecting the quality of image imaging, making imaging 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 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) with appropriate 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 ...
