Abstract

The invention provides a scanning device and a code scanning method thereof. The scanning device comprises a scanning engine used for collecting a bar code image; a main control unit used for analyzing the bar code image and decoding the bar code image; a storage unit used for providing a storage space; Wherein the scanning device is configured to have a learning mode and a code scanning mode, inthe learning mode, the main control unit controls the scanning engine to collect a bar code image, and the main control unit further analyzes and decodes the bar code image and stores an exposure parameter when the successfully decoded bar code image is collected in the storage unit; And in a code scanning mode, the main control unit calls the exposure parameters stored in the storage unit to carry out the same exposure setting on the scanning engine so as to control the scanning engine to collect a bar code image, and the main control unit further analyzes and decodes the bar code image.

Description

technical field [0001] The invention relates to a scanning device and a code scanning method thereof, in particular to a scanning device and a code scanning method for improving code scanning efficiency. Background technique [0002] An existing barcode reader includes an image sensor and a main control chip, the image sensor is used to capture barcode images, and the main control chip is used to decode. Usually, in order to improve the efficiency of barcode reading, the image sensor adopts the automatic exposure mode to adjust the exposure time of the next frame of barcode image according to the exposure time of the previous frame of barcode image capture and the brightness of the environment, so that the exposure time gradually converges to a suitable value. value. However, in the above-mentioned convergence process, the exposure time usually converges from the maximum value or the minimum value to an appropriate value many times, which is slow and inefficient.
