Description
Technical field
The present invention relates to a kind of methods carrying out Image Acquisition using scanning device.
Background technology
When scanning device carries out Image Acquisition, for example, during hand-held bar code scan rifle scans bar code, such as
The distance between fruit camera lens module and target image are improper, too close or too far all the image collected information may be caused unclear
It is clear, and then influence scanning result.Then it needs, by ambulatory handheld bar code scanner or target image, to adjust between the two
Distance reaches suitable range, to obtain optimum scanning effect, improves scanning result accuracy.However specifically how to adjust
（Including moving direction, distance etc.）Scanning effect could be improved, it is often necessary to it continuously attempts to, it is time-consuming and laborious.
Invention content
The purpose of the present invention is to provide a kind of methods carrying out Image Acquisition using scanning device, improve to convenient and efficient
Effect is scanned, scanning result accuracy is improved.
Based on considerations above, the present invention proposes that a kind of method carrying out Image Acquisition using scanning device, scanning device are swept
Retouch target image；Harmonic moving is carried out by controlling camera lens module, captures the image of different distance.
Preferably, the distance that target image is judged by the displacement of circuit detector lens module, it is same according to the difference of distance
The brightness of step section flash lamp.
Preferably, by the resonant frequency of circuit detector lens module, corresponding active force is provided.
Preferably, for the scanning device since power on, the camera lens module persistently carries out harmonic moving.
Preferably, the amplitude of the camera lens module is more than or equal to 0.5 millimeter.
Preferably, described image is bar code.
The method that Image Acquisition is carried out using scanning device of the present invention, when scanning device scans target image,
Harmonic moving is carried out by controlling camera lens module, captures the image of different distance, improves scanning effect to convenient and efficient, carries
High scanning result accuracy.

Sign, objects and advantages will become more apparent upon.
Fig. 1 is the method schematic diagram that Image Acquisition is carried out using scanning device of the present invention.
Specific implementation mode
To solve above-mentioned the problems of the prior art, the present invention provides a kind of side carrying out Image Acquisition using scanning device
Method carries out harmonic moving by controlling camera lens module, captures the figure of different distance when scanning device scans target image
Picture improves scanning effect to convenient and efficient, improves scanning result accuracy.
It, will be with reference to the appended attached drawing for constituting a present invention part in the specific descriptions of following preferred embodiment.Institute
Attached attached drawing, which has been illustrated by way of example, can realize specific embodiment.Exemplary embodiment is not intended to
Limit all embodiments according to the present invention.It is appreciated that without departing from the scope of the present invention, other can be utilized
Embodiment can also carry out structural or logicality modification.Therefore, it is below specific descriptions and it is unrestricted, and this
The range of invention is defined by the claims appended hereto.
The present invention proposes a kind of method carrying out Image Acquisition using scanning device, and target image is scanned in scanning device
When, harmonic moving is carried out by controlling camera lens module, captures the image of different distance.As shown in Figure 1, with camera lens module 2
Harmonic moving（Amplitude A is greater than equal to 0.5 millimeter）, the distance between camera lens module 2 and target image 1 d constantly changes,
Camera lens module 2 captures the image of different distance respectively, through comparative analysis（Such as mould is analyzed by the calculating that scanning device carries
Block）Optimized image information is obtained, improves scanning effect to convenient and efficient, improves scanning result accuracy.
Preferably, the distance of target image can be judged by the displacement of circuit detector lens module, not according to distance
With the brightness for being adjusted in synchronism flash lamp, that is to say, that suitable according to the distance between camera lens module and target image Auto-matching
Brightness of flash lamp improve scanning result accuracy further to improve scanning effect.
Preferably, the scanning device by the resonant frequency of circuit detector lens module, provides correspondence since power on
Active force so that camera lens module persistently carries out harmonic moving.
Preferably, described image is bar code, and the scanning device is hand-held bar code scan rifle.
The method that Image Acquisition is carried out using scanning device of the present invention, when scanning device scans target image,
Harmonic moving is carried out by controlling camera lens module, captures the image of different distance, improves scanning effect to convenient and efficient, carries
High scanning result accuracy.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
How from the point of view of, the present embodiments are to be considered as illustrative and not restrictive.In addition, it will be evident that one word of " comprising " not
Exclude other elements and step, and wording "one" be not excluded for plural number.The multiple element stated in device claim also may be used
To be realized by an element.The first, the second equal words are used to indicate names, and are not represented any particular order.
