Embodiment
Below with reference to accompanying drawing, specific embodiments of the invention are described in further detail.
As shown in Figure 1, a kind of bidirectional imaging device 1 of embodiment, comprise the first camera lens 11, second camera lens 12, catoptron 15, mirror axis 19 and photosensitive unit 18, mirror axis 19 is arranged between the first camera lens 11 and the second camera lens 12, catoptron 15 can rotate around mirror axis 19, when catoptron 15 rotates the second place extremely as shown in Figure 1, the reflecting surface of catoptron 15 is towards the second camera lens 12, be reflected onto on photosensitive unit 18 after entering the light arrival catoptron 15 of the second camera lens 12, namely can send processor to and carry out follow-up identifying processing; When catoptron 15 rotates primary importance extremely as shown in Figure 2, the reflecting surface of catoptron 15, towards the first camera lens 11, is reflected onto on photosensitive unit 18 after entering the light arrival catoptron 15 of the first camera lens 11.
Make its image quality better in order to reduce veiling glare on the impact of bidirectional imaging device 1, can camera lens 11, second camera lens 12 and catoptron 15 be encapsulated in housing 10, as shown in Figures 1 to 3, housing 10 is provided with housing chamber 17, first camera aperture 13, second camera aperture 14, first camera lens 11 and the second camera lens 12 are arranged in the first camera aperture 13 and the second camera aperture 14 respectively, and catoptron 15 and mirror axis 19 are arranged in housing chamber 17.
Like this, when catoptron 15 rotates to primary importance, housing chamber 7 is separated into two sub-housing chambeies be not connected by just, the light of thoroughly coming in from the first camera lens 11 is reflexed to photosensitive unit 18 by catoptron 15, and even without utilizing overcover to be sheltered from by the second camera lens 12, the light of thoroughly coming in from the second camera lens 12 also cannot enter photosensitive unit 18; In like manner, when catoptron 15 rotates to the second place, housing chamber 7 is also separated into two sub-housing chambeies be not connected by it, and the light of thoroughly coming in from the second camera lens 12 is reflexed to photosensitive unit 18 by catoptron 15.Like this, namely can avoid, when a camera lens job, being subject to the impact of the veiling glare from another camera lens, and need not being blocked another one camera lens by additional shelter.
How to make catoptron 15 housing chamber 17 can be separated into two sub-housing chambeies be not connected when primary importance or the second place, have multiple way.A kind of way is: the inwall in housing chamber 17 is respectively equipped with the first baffle plate 161 and second baffle 162 in the both sides of the first camera aperture 13, housing chamber 17 inwall is respectively equipped with third gear plate 163 and fourth gear plate 164 in the both sides of the second camera aperture 14, when catoptron 15 is in primary importance, the first rotational end 151 of catoptron 15 contacts with the first baffle plate 161 with third gear plate 163 respectively with the second rotational end 152; When catoptron 15 is in the second place, the first rotational end 151 of catoptron 15 contacts with second baffle 162 with fourth gear plate 164 respectively with the second rotational end 152.Another way is: catoptron 15 long enough, and when primary importance or the second place, the first rotational end 151 and the second rotational end 152 all can be close on the inwall in housing chamber 17, thus housing chamber 17 is separated into two spaces do not communicated.
The back side of the reflecting surface of catoptron 15 is black, and like this, when catoptron 15 is in the second place, the light thoroughly entered from the first camera lens 11 is difficult to reflex in photosensitive unit 18 after this backside reflection to the inwall in housing chamber 17 again and causes occurring veiling glare; In addition, the inwall in housing chamber 17 also also can reduce the veiling glare that a part of diffuse reflection brings to photosensitive unit 18 in black.
As shown in Figure 3, mirror axis 19 can drive by being arranged on driving mechanism 191 in housing 10 and rotate, and then drives catoptron 15 to rotate.Namely the second place can be arrived at catoptron 15 half-twist of primary importance.
Between photosensitive unit 18 and catoptron 15, be provided with color separation filler 101, color separation filler 101 is fixed on the inwall in housing chamber 17.
By this bidirectional imaging application of installation in the electronic device, on such as mobile phone, greatly can save the manufacturing cost of mobile phone.
As shown in Figures 4 and 5, if substituting as catoptron 15, adopt the reflection configuration 153 of similar prism shape, it has the first reflecting surface 154 and the second reflecting surface 155, reflection configuration 153 translation is switched with the work of the first camera lens 11 realized and the second camera lens 12, when reflection configuration 153 moves to position as shown in Figure 4, the light of thoroughly coming in from the second camera lens 154 reflexes on photosensitive unit 18 by the first reflecting surface 154, when reflection configuration 153 moves to position as shown in Figure 5, the light of thoroughly coming in from the first camera lens 11 reflexes on photosensitive unit 18 by the second reflecting surface 155.At the certain area of guarantee first reflecting surface 154 and the second reflecting surface 155 with on the basis can reflected all light of coming in, with on the identical image quality basis of guarantee, cavity space required for translation reflection configuration 153 is larger than the space needed for catoptron 15 rotated, and when the first reflecting surface 154 works, the reflected light of the second reflecting surface 155 is as easy as rolling off a log to be entered photosensitive unit 18 and affects image quality.
As shown in Figure 6, a kind of electronic equipment 2 of embodiment, it is equipped with described bidirectional imaging device 1, it can be arranged on the optional position of electronic equipment 2, and preferably offer through hole 21 to install described bidirectional imaging device 1 at electronic equipment 2, like this, electronic equipment can not only the function realizing bidirectional camera shooting of low cost, and installs also very convenient.
