Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Fig. 1 is the flow diagram of the recognition methods for the identification code that one embodiment of the present of invention provides, as shown in Figure 1
The recognition methods of identification code the described method comprises the following steps applied to the terminal comprising photographing module:
Step 101, in the case where putting out screen state, it is default to determine whether occupied area ratio of the identification code in barcode scanning frame is less than
Value.
Wherein, identification code can include the bar code of information, the letter for including for one-dimension code (for example, bar code), two dimensional code etc.
Breath can be picture, network linking etc..
If so, executing step 102, step 103；If it is not, executing step 103.
Step 102, adjust the focal length of photographing module with increase occupied area ratio of the identification code in barcode scanning frame to more than
Equal to preset value.
Step 103, control photographing module scanning recognition code, and identify the identification code that scanning is arrived.
Through this embodiment, in the case where putting out screen state, when appearance because occupied area ratio of the identification code in barcode scanning frame is less than
When the case where preset value, the focal length of adjust automatically photographing module is to increase identification code occupied area ratio in barcode scanning frame, later,
Scanning recognition code again avoids because of identification code occupied area ratio smaller the case where can not successfully identifying, and user is not required to
Carry out it is a series of triggering barcode scanning functions operations can scanning recognition code, reduce the operation of user, and then improve identification
Discrimination, recognition speed and the convenience of identification code.
Fig. 2 be another embodiment of the present invention provides identification code recognition methods flow diagram, it is shown in Fig. 2
Embodiment and above-mentioned embodiment shown in FIG. 1 the difference is that, after step 103, can also include:
Step 104, when being identified successfully to the identification code scanned, bright screen simultaneously show with the associated information of identification code.
User can according to being paid with the associated information of identification code of display, registration information, addition good friend, anti-fake look into
Ask etc..Specifically, associated information can be picture, network linking etc..
As shown in Fig. 2, can also include: after step 103
When to the identification code recognition failures scanned, return step 101.
Pass through this embodiment, additionally it is possible to which after scanning to identification code, bright screen simultaneously executes corresponding behaviour according to recognition result
Make.
In one embodiment of the present invention, before above-mentioned steps 101, may include:
The photographing module is controlled with first frequency to being scanned in its visual field, and obtains scanning result；
Above-mentioned steps 101 may include:
Determine that there are when identification code, determine occupied area ratio of the identification code in barcode scanning frame in visual field according to scanning result
Whether preset value is less than.
Wherein, visual field is the regional scope that can be scanned and identify.
By this embodiment, compared to the prior art in carry out it is a series of triggering barcode scanning functions operations (for example, point
Hit APP application icon-selection barcode scanning function) scheme that just can be carried out barcode scanning, by control photographing module with first frequency to it
It is scanned in visual field, and judges automatically in visual field according to scanning result that there are when identification code, determine identification code in barcode scanning frame
Occupied area ratio whether be less than preset value so that do not need user carry out it is a series of triggering barcode scanning functions operations, energy
Enough scans there are when identification code in the visual field of photographing module and identify identification code.
Specifically, determining that there are identification codes in the visual field of photographing module when identification code characteristic point is arrived in scanning.For example, working as
When scanning two dimensional code characteristic point, determine that there are two dimensional codes in the visual field of photographing module.
In one embodiment of the present invention, first frequency is less than the frequency of photographing module scanning recognition code.
By this embodiment, first frequency is less than the frequency of photographing module scanning recognition code, can reduce photographing module
To the power consumption scanned in visual field, and then it can reduce the power consumption of mobile terminal identification identification code.
Specifically, above-mentioned photographing module can be the camera with low-power consumption mode, under low-power consumption mode, mould is imaged
Block can be with first frequency to being scanned in its visual field.
