Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present inventionIn accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment isThe a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the artThe every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
Fig. 1 is the flow chart of two-dimensional code scanning processing method embodiment of the present invention.As shown in figure 1, the two dimension of the present embodimentCode scanning processing method includes:
S11: when startup photographic head is scanned to target Quick Response Code, the default resolution of described photographic head is reduced toScanning resolution；
Wherein, default resolution refers to the resolution of photographic head default setting, and scanning resolution refers to photographic head and existsThe resolution arranging during to two-dimensional code scanning；Scanning resolution is less than default resolution.
It should be noted that the embodiment of the present invention can be using any intelligence having and being provided with two-dimensional code scanning recognizerEnergy mobile phone, panel computer etc., the embodiment of the present invention is without limitation.Two-dimensional code scanning recognizer can be mounted in movementApp in terminal, can be by being scanned to the picture with Quick Response Code knowing to the positioning of Quick Response Code, segmentation and decoding operateNot.
For example, the resolution of the photographic head of mobile terminal has 1024 × 768,1600 × 1200,2048 × 1,536 3Kind, its default resolution is 2048 × 1536, and scanning resolution is set to 1024 × 768.Starting photographic head to target two dimensionCode when being scanned, the resolution of photographic head is reduced to scanning resolution, and that is, 1024 × 768.
S12: gather the image of described target Quick Response Code based on described scanning resolution, and Quick Response Code is carried out to described imageDecoding process.
