The first embodiment describes a two-camera apparatus when a first light entrance lens and a second light entrance lens are placed opposite to each other. When the first light inlet lens and the second light inlet lens are oppositely arranged, the fixed reflector component at least comprises three fixed reflectors. The light rays incident from the first light inlet lens are reflected by the three fixed reflectors in sequence and then reach the movable reflector at the first preset position, and are reflected to the photosensitive device through the movable reflector at the first preset position. When the light rays are detected to be incident from the second light entering lens, the movable reflector is moved to a second preset position, so that the light rays incident from the second light entering lens are directly transmitted to the photosensitive device. Compared with a double-camera device in the prior art, the double-camera device has the advantages that only one photosensitive device is used for processing the light rays incident from the first light inlet lens and the second light inlet lens respectively, the structure is more compact, the number of used components is less, and the manufacturing cost is cheaper.
As shown in fig. 4(a) and 4(b), a second embodiment of the present application proposes a dual-camera device, which is applied to the mobile terminal described above, and specifically includes the following components:
a first light entering lens 301, a second light entering lens 302, a movable reflector 303, a photosensitive device 304 and a fixed reflector component 305 at least comprising one fixed reflector;
the second light entrance lens 302 is disposed in parallel on one side of the first light entrance lens 301, the light sensing device 304 is disposed between the first light entrance lens 301 and the second light entrance lens 302, and the movable mirror 303 is disposed between the light sensing device 304 and the second light entrance lens 302.
As shown in fig. 4(a), when the movable mirror 303 moves to the first preset position, the light incident from the first light entering lens 301 changes the light transmission direction by the fixed mirror assembly 305 and reaches the movable mirror 303, and then reaches the photosensitive device 304 after being reflected by the movable mirror 303.
As shown in fig. 4(b), when the movable mirror 303 is moved to the second preset position, the light incident from the second light entering lens 302 directly reaches the light sensing device 304.
Specifically, the first light entering lens 301 and the second light entering lens 302 are used for collecting external light rays in two different directions. The first light-entering lens 301 and the second light-entering lens 302 are equivalent to a light-entering lens of a front camera and a light-entering lens of a rear camera in a conventional dual-camera mobile phone.
The moving mirror 303 is movable between a first preset position and a second preset position. When the light incident from the first light entering lens 301 is detected, the movable mirror 303 is moved to a first preset position; when the light incident from the second light entering lens 302 is detected, the movable mirror 303 is moved to a second preset position.
The fixed mirror assembly 305 is used to change the transmission direction of the light incident from the first entrance lens 301 so that the light incident from the first entrance lens 301 is transmitted to the photo-sensing device 304.
The light sensing device 304 is used to process the light into a corresponding image.
Further, the light receiving end surface of the light sensing device 304 faces the second light entering lens 302, the light receiving end surface of the light sensing device 304 faces the mirror surface of the movable reflector 303, and the mirror surface of the movable reflector 303 and the light receiving end surface of the light sensing device 304 form an included angle of 45 degrees;
when the movable mirror 303 is moved to the first preset position, the center of the light receiving end surface of the light sensing device 304, the center of the movable mirror 303, and the center of the second light entering lens 302 are located on a straight line.
Further, the apparatus further comprises: a drive motor;
the driving motor is used for driving the movable mirror 303 to move from the first preset position to the second preset position along the vertical direction or the horizontal direction.
When the driving motor drives the movable mirror 303 to move to the first preset position, the movable mirror 303 receives the light transmitted by the fixed mirror assembly 305, and reflects the light onto the photosensitive device 304.
The second preset position is in the vertical direction or the horizontal direction of the first preset position. When the driving motor drives the movable mirror 303 to move to the second preset position, the light incident from the second light entering lens 302 is not blocked by the movable mirror 303 and can be directly transmitted to the photosensitive device 304.
Further, in this embodiment, the first light entrance lens 301 and the second light entrance lens 302 are not disposed opposite to each other, and the fixed mirror assembly 305 includes only: a fixed mirror 3054.
The mirror surface of the fixed mirror 3054 faces the first light entering lens 301, and the mirror surface of the fixed mirror 3054 is opposite to and perpendicular to the mirror surface of the movable mirror 303; the light incident from the first light entering lens 301 is vertically incident to the fixed mirror 3054; when the movable mirror 303 is moved to the first preset position, a line connecting the center of the fixed mirror 3054 and the center of the movable mirror 303 is perpendicular to a line connecting the center of the first light entering lens 301 and the center of the fixed mirror 3054.
When the first light entrance lens and the second light entrance lens are not arranged oppositely, the fixed reflector assembly at least comprises one fixed reflector, but in practical application, the number of the fixed reflectors in the fixed reflector assembly and the placement position of each fixed reflector are not limited to the above-mentioned one.
Further, the apparatus further comprises: an infrared filter;
the infrared filter is located between the photosensitive device 304 and the movable reflector 303, the infrared filter is parallel to the light receiving end face of the photosensitive device 304, and light reflected by the movable reflector 303 or light incident from the second light entering lens 302 is processed by the infrared filter and then transmitted to the photosensitive device 304.
Furthermore, the mirror surfaces of the fixed reflector and the movable reflector are provided with reflecting coatings, and the mirror backs of the fixed reflector and the movable reflector are provided with light absorbing coatings.
The second embodiment describes a two-camera apparatus when the first light entrance lens and the second light entrance lens are not placed opposite to each other. When the first light inlet lens and the second light inlet lens are not oppositely arranged, the fixed reflector component at least comprises one fixed reflector. The light rays incident from the first light inlet lens are reflected by the fixed reflector in sequence, then reach the movable reflector at the first preset position, and are reflected to the photosensitive device by the movable reflector at the first preset position. When the light rays are detected to be incident from the second light entering lens, the movable reflector is moved to a second preset position, so that the light rays incident from the second light entering lens are directly transmitted to the photosensitive device. Compared with a double-camera device in the prior art, the double-camera device has the advantages that only one photosensitive device is used for processing the light rays incident from the first light inlet lens and the second light inlet lens respectively, the structure is more compact, the number of used components is less, and the manufacturing cost is cheaper.
A third embodiment of the present application proposes a mobile terminal including the dual-camera device described in the first embodiment or the second embodiment.
When the mobile terminal adopts the double-camera device introduced above, the front-mounted camera and the rear-mounted camera share one set of camera module, so that the number of components is reduced, and the defect of poor imaging effect of the front-mounted camera can be overcome.
