Embodiment
Below with reference to accompanying drawing, specific embodiments of the invention are described in further detail.
As shown in Figure 1, the bidirectional imaging device 1 of a kind of embodiment, comprise the first camera lens 11, the 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 rotation during to as shown in Figure 1 the second place, the reflecting surface of catoptron 15 is towards the second camera lens 12, be reflected onto on the photosensitive unit 18 after the light that enters the second camera lens 12 arrives catoptron 15, namely can send processor to and carry out follow-up identifying processing; When catoptron 15 rotation during to as shown in Figure 2 primary importance, the reflecting surface of catoptron 15 is towards the first camera lens 11, is reflected onto on the photosensitive unit 18 after the light that enters the first camera lens 11 arrives catoptron 15.
In order to reduce veiling glare on the impact of bidirectional imaging device 1 and so that its image quality is better, one camera lens 11, the second camera lens 12 and catoptron 15 can be encapsulated in the housing 10, as shown in Figures 1 to 3, housing 10 is provided with housing chamber 17, the first camera aperture 13, the second camera aperture 14, the first camera lens 11 and the second camera lens 12 are installed in respectively in the first camera aperture 13 and the second camera aperture 14, and catoptron 15 and mirror axis 19 are installed in the housing chamber 17.
Like this, when catoptron 15 rotates to primary importance, it is separated into housing chamber 7 two sub-housing chambeies that are not connected just, the light of thoroughly coming in from the first camera lens 11 is reflected mirror 15 and reflexes on the photosensitive unit 18, and even without utilizing overcover that the second camera lens 12 is sheltered from, the light of thoroughly coming in from the second camera lens 12 also can't enter on the photosensitive unit 18; In like manner, when catoptron 15 rotated to the second place, it also was separated into housing chamber 7 two sub-housing chambeies that are not connected, and the light of thoroughly coming in from the second camera lens 12 is reflected mirror 15 and reflexes on the photosensitive unit 18.Like this, namely can avoid when a camera lens job, being subject to the impact from the veiling glare of another camera lens, and need not blocking the another one camera lens by additionally setting up shelter.
How so that catoptron 15 can be separated into housing chamber 17 two sub-housing chambeies that are not connected when primary importance or the second place, multiple way is arranged.A kind of way is: be respectively equipped with the first baffle plate 161 and second baffle 162 on the inwall in housing chamber 17 and in the both sides of the first camera aperture 13, be respectively equipped with the 3rd baffle plate 163 and the 4th baffle plate 164 on 17 inwalls of housing chamber and in the both sides of the second camera aperture 14, when catoptron 15 was in primary importance, the first rotation terminal 151 of catoptron 15 contacted with the first baffle plate 161 with the 3rd baffle plate 163 respectively with the second rotation terminal 152; When catoptron 15 was in the second place, the first rotation terminal 151 of catoptron 15 contacted with second baffle 162 with the 4th baffle plate 164 respectively with the second rotation terminal 152.Another way is: catoptron 15 long enoughs, when primary importance or the second place, terminal the 151 and second rotation terminal 152 of the first rotation all can be close on the inwall in housing chamber 17, thereby housing chamber 17 is separated into two spaces that do not communicate.
The back side of the reflecting surface of catoptron 15 is black, and like this, when catoptron 15 was in the second place, the light that thoroughly advances from the first camera lens 11 was difficult to reflex to the inwall in housing chamber 17 in the photosensitive unit 18 again and cause occurring veiling glare through this backside reflection; In addition, the inwall in housing chamber 17 also is black and also can reduces the veiling glare that a part of diffuse reflection brings to photosensitive unit 18.
As shown in Figure 3, mirror axis 19 can drive and rotates by being installed in the interior driving mechanisms 191 of housing 10, and then drives catoptron 15 rotations.Catoptron 15 half-twists in primary importance namely can arrive the second place.
Be provided with color separation filler 101 between photosensitive unit 18 and catoptron 15, color separation filler 101 is fixed on the inwall in housing chamber 17.
This bidirectional imaging application of installation in electronic equipment, on mobile phone, can be saved the manufacturing cost of mobile phone greatly.
Shown in Figure 4 and 5, if as substituting of 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 translations are switched with the first camera lens 11 of realization and the work of the second camera lens 12, when reflection configuration 153 moves to as shown in Figure 4 position, the first reflecting surface 154 will reflex to from the light that the second camera lens 154 is come in thoroughly on the photosensitive unit 18, when reflection configuration 153 moved to as shown in Figure 5 position, the second reflecting surface 155 will reflex on the photosensitive unit 18 from the light that the first camera lens 11 is come in thoroughly.Guaranteeing on the basis that the first reflecting surface 154 and the second reflecting surface 155 certain areas reflect with the light that can thoroughly come in to all, on guaranteeing identical image quality basis, the needed cavity space of translation reflection configuration 153 space more required than the catoptron 15 of rotation is larger, and when the work of the first reflecting surface 154, 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, the electronic equipment 2 of a kind of embodiment, it is equipped with described bidirectional imaging device 1, it can be installed in the optional position of electronic equipment 2, offer through hole 21 so that described bidirectional imaging device 1 to be installed and be preferably in electronic equipment 2, like this, electronic equipment not only can be realized the function of bidirectional camera shooting cheaply, and installs also very convenient.
