Description
Technical field
The utility model relates to a kind of mobile phone camera, especially relates to a kind of two mega pixel mobile phone cameras with iris identifying function, belongs to mobile phone camera technical field.
Background technology
At present, along with the large-scale application of mobile communication, mobile phone etc. are paid by mails and have been dissolved in daily life, and in payment process, people protect by utilizing codon pair personal account; But pin mode is not only easily forgotten, and exist by the possibility of Brute Force; Therefore in order to improve security performance, identity recognizing technology based on biological characteristic starts extensive use, these recognition technologies with identity characteristic have " people respectively have different, throughout one's life constant, carry with " three features, have stable, portable, the not easily advantage such as imitation, because become the focus of identity verify in recent years; As now conventional fingerprint recognition, but fingerprint identification technology has following shortcoming: when integrated on mobile terminals time need to add extra fingerprint collecting hardware module, not only destroy the appearance looks elegant degree of mobile terminal, increase the volume of mobile terminal, and add the cost of mobile device.In addition, because the fingerprint of people is easily forged, therefore do not utilize and be applied in the information security issue of higher level.In addition, fingerprint, as the feature being exposed to human body surface, is also easily subject to ectocine and damaged, such as, be subject to wound, therefore cannot as a kind of effective and stable personal identification method;
People turn to another identity characteristic for this reason---iris, and iris is a part of eyes, and be the annular tissue between pupil and sclera, the iris patterns of every eyes is different, and unchangeable; Iris recognition has the advantages such as uniqueness is high, stability is strong, non-infringement, has been successfully applied to airport, customs, bank, the identity authentication of the occasions such as prison;
And compared to other RMs, iris recognition, by scanning the iris of human eye, can realizing the identification of pinpoint accuracy, therefore utilizing the camera that mobile phone carries can complete corresponding identity recognition function, without the need to increasing additional hardware; For this reason, a kind of brand-new mobile phone iris recognition camera head of exploitation is needed badly, to solve the problem of other recognition technologies above-mentioned.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of two mega pixel mobile phone cameras with iris identifying function that can carry out identification.
The purpose of this utility model is achieved in that
A kind of two mega pixel mobile phone cameras with iris identifying function, described camera includes substrate, described substrate front side is pasted with transducer, described substrate is also provided with base, described base is connected with camera lens, described camera lens is positioned at the top of transducer, and is provided with filter between transducer and camera lens, and described filter is coated with reflectance coating.
A kind of two mega pixel mobile phone cameras with iris identifying function of the utility model, described substrate back is provided with golden finger, and described golden finger is electrically connected by the printed wire on substrate and transducer.
A kind of two mega pixel mobile phone cameras with iris identifying function of the utility model, described reflectance coating is visible light reflecting film.
A kind of two mega pixel mobile phone cameras with iris identifying function of the utility model, the width of described base is 5.2 ± 0.05mm, and the width of described substrate is 5.1 ± 0.05mm.
A kind of two mega pixel mobile phone cameras with iris identifying function of the utility model, described filter transmission wavelength is the infrared light of 760 ~ 825mm.
A kind of two mega pixel mobile phone cameras with iris identifying function of the utility model, the angle of visual field of described camera lens is 29deg, and object distance is 25 ~ 45cm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the setting of the reflectance coating on filter and filter, eliminates stray light to the impact of iris recognition; And by reflect visible light, transmission specific wavelength infrared light, even if thus make also can carry out accurate iris recognition when insufficient light; In addition, by mating the size of base and substrate, reducing the volume of camera, contributing to realizing miniaturization; Meanwhile, the golden finger being used for realizing with mobile phone being connected being set by back, making when applying, the utility model camera is installed more convenient, as long as carry out laminating welding operation as to surface mount elements on cell phone mainboard; Finally, by the selection through the angle of view and object distance, while ensureing accuracy of identification, reduce the manufacturing cost of camera, be conducive to the market competitiveness improving camera, contribute to the all-round popularization application of iris recognition technology on mobile phone.

Embodiment
See Fig. 1 ~ 5, a kind of two mega pixel mobile phone cameras with iris identifying function that the utility model relates to, described camera includes substrate 1, described substrate 1 front is pasted with transducer 2, described substrate 1 back side is provided with golden finger 1.1, described golden finger 1.1 is electrically connected by the printed wire on substrate 1 and transducer 2, described substrate 1 is also provided with base 3, the width of described base 3 is 5.2 ± 0.05mm, the width of described substrate 1 is 5.1 ± 0.05mm, thus make the width of base 3 slightly larger than the width of substrate 1, reduce periphery amount of redundancy, reduced volume, being convenient to mobile phone realizes miniaturized, described base 3 is connected with camera lens 4, described camera lens 4 is positioned at the top of transducer 2, and be provided with filter 5 between transducer 2 and camera lens 4, described filter 5 is coated with reflectance coating, ensure accuracy rate during iris recognition,
Preferably, described reflectance coating is visible light reflecting film, thus makes filter 5 transmission peak wavelength be the infrared light of 760 ~ 825mm; Ensure also to identify iris when light is more weak;
Preferably, the angle of visual field of described camera lens 4 is 29deg, and object distance is 25 ~ 45cm, and the reduction angle of visual field and object distance contribute to reducing production cost; And for red film identification, because glasses during scanning are relatively near camera lens, the therefore less angle of visual field, shorter object distance can ensure the precision of iris recognition completely;
