Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] In view of the prior art, the terminal needs to decode the two-dimensional code in the displayed video image, and then generate a two-dimensional code with a larger display area according to the content of the two-dimensional code, and display it on the terminal screen, so as to facilitate users Scan to obtain the two-dimensional code information. When the terminal decodes the two-dimensional code in the video image it displays, the terminal needs to analyze and decode the entire video image to obtain the content of the two-dimensional code in the video image. The two-dimensional code of the terminal The processing burden of the two-dimensional code deco...

Abstract

The invention provides a quick decoding method and device for a QR code, and the method comprises the steps: scanning a video image at a first preset scanning density, and determining the region of the QR code; scanning and decoding a video image in the region of the QR code at a second preset scanning density. Because the first scanning just determines the region of the QR code, the scanning speed is high and the time is short; the second scanning just scans and decodes the region of the QR code, and the scanning and decoding region is small, so the processing burden of the quick decoding device for the QR code is reduced, the locating and decoding time of the QR code is shortened, and the decoding efficiency of the QR code is improved.

Description

[0001] This application is a divisional application of the Chinese invention patent application 201610100825.X filed on February 23, 2016 with the title of "Quick Decoding Method and Device for Two-Dimensional Code". technical field [0002] The invention relates to the technical field of image analysis and processing, in particular to a two-dimensional code fast decoding method and device. Background technique [0003] QR code (Quick Response Code, QR code for short) is a very popular coding method on mobile devices in recent years. Two-dimensional codes can express information graphically in both horizontal and vertical orientations at the same time, so a large amount of information can be expressed in a small area. [0004] At present, for example, for the two-dimensional codes appearing in video images of video playback terminals such as TVs, due to their small display area and short dwell time, such two-dimensional codes are usually firstly converted by the terminal dis...
