For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, for the schematic flow sheet of the image reading method embodiment of a kind of dynamic-configuration decoding parametric provided by the invention, the method can be applied to electronic equipment, this electronic equipment can comprise camera and display, if this electronic equipment can be mobile phone, ipad etc., the application does not do concrete restriction to this, and in actual applications, the information processing method that the present embodiment provides can comprise the following steps:
Step S110: target electronic device obtains the default decoding parametric matched with self.
In the present embodiment practical application, when after the electronic equipment determining decoding to current point configuration Quick Response Code and target electronic device, in order to ensure the success ratio that this target electronic device is decoded to current point configuration Quick Response Code, target electronic device can first obtain presets decoding parametric with self, and the application is not construed as limiting the specific implementation that it obtains.
Wherein, this default decoding parametric can comprise: ISO (Isolation) value under camera preview resolution, Scanning size (i.e. square view-finder size), focal modes, various light condition and exposure bias value, the parameter of image binaryzation, the parameter of decoding algorithm etc.; the application does not do concrete restriction to this; as long as the parameter being decoded into power for improving dot matrix Quick Response Code all belongs to the application's protection domain, the present embodiment describes in detail no longer one by one at this.In addition, this dot matrix Quick Response Code can be specifically a kind of good fortune code with anti-copying and non-boundary characteristic, but is not limited thereto.
It should be noted that, about the decoding parametric how determining to mate with target electronic device, the application does not limit its specific implementation, optionally, existing parameter calibration method can be adopted to test target electronic device, thus obtain the decoding parametric mated with it, but be not limited thereto.
Concrete, by choosing major part or representational part of cell phone on the market, (the application is only that mobile phone is described for electronic equipment at this, other electronic equipment implementations are similar, the application describes in detail no longer one by one), by removing the decoding parametric needed for demarcation manually, namely the tool software of specialty is used, lot of experiments is carried out to a large amount of dot matrix Quick Response Code code figure sample, thus determines that using this mobile phone to be decoded into one group of the highest decoding parametric of power to dot matrix Quick Response Code is the default decoding parametric matched with this mobile phone.Afterwards, by gained and the decoding parametric matched of this mobile phone and the identification information association store of this mobile phone self to server, so that user directly transfers the default decoding parametric mated with it according to handset identification information used, but can be not limited thereto.
Wherein, server side can provide the interpolation of decoding parametric, editor, deletes, checks, combine the functions such as configuration, user can therefrom obtain required decoding parametric by presetting communication interface, it should be noted that, when user obtains the default decoding parametric mated with mobile phone, user can edit it according to actual conditions, screens, reconfigure, and the present embodiment does not do concrete restriction to this.
In addition, it should be noted that, in actual applications, in order to improve the success ratio that every Mobile phone is on the market decoded to dot matrix Quick Response Code further, also can carry out test calibration by Mobile phone Mobile phone, to obtain the decoding parametric of every Mobile phone coupling, the application is not construed as limiting this.
Based on above-mentioned analysis, when there being the mobile phone of trendy listing, can the decoding parametric that mates with it of test calibration in the manner described above, the success ratio using this mobile phone to decode to dot matrix Quick Response Code can be ensured, meanwhile, the identification information of the decoding parametric of acquisition and this mobile phone can also be uploaded onto the server, wherein, this identification information can comprise the brand, model etc. of mobile phone, and the application is not construed as limiting this.
