Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
< embodiment 1 >
As shown in fig. 1, 2, and 3, a camera device 5 according to embodiment 1 of the present invention is housed in a housing 9 of a smartphone 8. The camera device 5 includes: as a function of the front camera, capturing light incident through the 1 st entrance port 1 from a subject located on the side of the smartphone 8 where the display 6 is present; and a function as a rear camera that photographs light incident from an object located on the back side thereof through the 2 nd incident port 2. The camera device 5 includes: a 1 st reflector 10 having a 1 st reflecting surface 11 and a 2 nd reflector 20 having a 2 nd reflecting surface 22; a condenser lens 30 for condensing the light reflected by the 1 st reflector 10 or the 2 nd reflector 20; and an image sensor 40 that photoelectrically converts light from the condenser lens 30.
Here, in an orthogonal coordinate system having mutually orthogonal X, Y, and Z axes, the thickness direction of the smartphone 8 is referred to as the Z-axis direction. The optical axis direction of the condenser lens 30 is referred to as the Y-axis direction, and the direction orthogonal to the Z-axis direction and the Y-axis direction is referred to as the X-axis direction. In addition, the + Z side, which is the side of the 1 st entrance port 1, and the-Z side, which is the side of the 2 nd entrance port 2, of the housing 9 of the smartphone 8 may be referred to as the front side, and the rear side, respectively. The + Y side is sometimes referred to as the upper side, and the-Y side is sometimes referred to as the lower side. Here, the 1 st reflector 10 is a reflector that reflects light from the front side and enters the condenser lens 30, and the 2 nd reflector 20 is a reflector that reflects light from the rear side and enters the condenser lens 30.
The camera device 5 is incorporated in the smartphone 8 in a posture in which the optical axis of the condenser lens 30 is directed in the direction of the inside of the surface of the smartphone 8. The image sensor 40 has a light receiving surface facing the condenser lens 30, and is disposed below the condenser lens 30. The 1 st reflector 10 and the 2 nd reflector 20 are integrated so as to intersect each other so that the outline thereof when viewed in the X direction is X-shaped, and are disposed above the condenser lens 30. At this time, the 1 st entrance port 1 and the 2 nd entrance port 2 are arranged along the Z-axis direction, and the 1 st reflector 10 and the 2 nd reflector 20 are arranged between the 1 st entrance port 1 and the 2 nd entrance port 2. Both the 1 st reflector 10 and the 2 nd reflector 20 directly face the condenser lens 30.
The 1 st reflector 10 and the 2 nd reflector 20 are formed of a light control material which is switched in a mirror/transparent state according to an applied voltage. The light control material has a laminated structure in which one or more functional layers are laminated on a transparent base material. For details of the laminated structure of the light control material, refer to non-patent document 1.
As shown in fig. 4 and 5, the 1 st reflecting surface 11 of the 1 st reflector 10 is arranged to be inclined at 45 degrees with respect to the optical axis direction of the condenser lens 30 in the ZY plane. The 2 nd reflecting surface 22 of the 2 nd reflecting body 20 is inclined at 45 degrees with respect to the optical axis and at 90 degrees with respect to the 1 st reflecting surface 11 in the ZY plane. That is, light entering the 1 st entrance port 1 from the + Z-axis direction is reflected by the 1 st reflecting surface 11 along the-Y-axis direction and enters the condenser lens 30. Light incident on the 2 nd incident port 2 from the-Z axis direction is reflected by the 2 nd reflecting surface 12 along the-Y axis direction and enters the condenser lens 30. The mirror/transparent states of the 1 st reflecting body 10 and the 2 nd reflecting body 20 can be switched forward and backward according to the operation of the smartphone 8.
If instructed to switch to the front camera mode, the 1 st reflector 10 becomes a mirror state and the 2 nd reflector 20 becomes a transparent state. As shown in fig. 4, in this state, light incident from the 1 st incident port 1 is emitted at each point of the front object, and is reflected by the entire surface of the 1 st reflecting surface 11 of the 1 st reflecting body 10, and the reflected light is condensed to a position corresponding to each point position of the object on the image sensor 40 via the condenser lens 30.
If instructed to switch to the rear camera mode, the 1 st reflector 10 becomes a transparent state and the 2 nd reflector 20 becomes a mirror state. As shown in fig. 5, in this state, light incident from the 2 nd incident port 2 is emitted at each point of the rear object, and is reflected by the entire surface of the 2 nd reflecting surface 22 of the 2 nd reflecting body 20, and the reflected light is condensed to a position corresponding to each point position of the object on the image sensor 40 via the condenser lens 30.
The 1 st reflector 10 and the 2 nd reflector 20 are formed in an X-shape in the following order, for example. As shown in fig. 6, a plurality of rod-shaped bodies 53 (4 in the example of fig. 6) were produced by forming a film of the light control material 52 on a plate-shaped optical glass substrate 51 as a transparent base material and cutting the film into a rectangular parallelepiped rod shape. Next, as shown in fig. 7, the plate-like bodies 54 are laminated and bonded to each other. Next, the plate-like body 54 is cut at equal intervals in a direction orthogonal to the stacking direction, such as a cutting line 61, to produce a plurality of rectangular parallelepiped rod-like bodies 55. Next, as shown in fig. 8, the light control material 56 is formed again on one side surface of each rod-like body 55, and the light control material is laminated and bonded to produce a plate-like body 57. Before film formation, the side surface may be smoothed by polishing (buffing) or the like. Further, the surface opposite to the side surface may be smoothed. Accordingly, the plate-like body 57 is obliquely cut so that the light control material 52 and the light control material 56 correspond to diagonal lines as shown by the cut line 62, and a compound prism 58 having a square side surface is produced as shown in fig. 9. The shape of the compound prism 58 approximates the shape of a dice. The cut surfaces cut at the cutting lines 62 are also smoothed by grinding (polishing) or the like. The light control material 52 in the composite prism 58 is one of the 1 st reflector 10 and the 2 nd reflector 20, and the light control material 56 is the other.
The above is the details of embodiment 1. The camera device 5 according to embodiment 1 includes: a condenser lens 30 having an optical axis; an image sensor 40 disposed below the condenser lens 30; a 1 st reflector 10 disposed above the condenser lens 30 and having a 1 st reflecting surface 11 inclined at 45 degrees with respect to the optical axis; and a 2 nd reflector 20 disposed above the condenser lens 30 and having a 2 nd reflecting surface 22 inclined at 45 degrees with respect to the optical axis and at 90 degrees with respect to the 1 st reflecting surface 11. Accordingly, both the 1 st reflector 10 and the 2 nd reflector 20 are directly opposed to the condenser lens 30 and are formed of a light adjusting material. Thus, if the mirror/transparency states of the 1 st reflector 10 and the 2 nd reflector 20 are switched, both the front side and the rear side can be imaged. Therefore, it is possible to provide a camera device 5 and an electronic apparatus that can use one image sensor for both a front camera and a rear camera without requiring a complicated mechanical structure.
< embodiment 2 >
As shown in fig. 10 to 12, the 1 st reflector 10 and the 2 nd reflector 20 of the camera device 5A according to embodiment 2 of the present invention are arranged in the vertical direction, and the 1 st reflector 10 is located above the 2 nd reflector 20. Since the 1 st entrance port 1 is located on the front side of the 1 st reflector 10 and the 2 nd entrance port 2 is located on the rear side of the 2 nd reflector 20, the position of the 2 nd entrance port 2 on the rear side is lower than the position of the 1 st entrance port 1 on the front side in the smartphone 8. On the lower side of the 2 nd reflector 20, there are a condenser lens 30 and an image sensor 40. The 1 st reflector 10 and the 2 nd reflector 20 are arranged such that the 1 st reflecting surface 11 and the 2 nd reflecting surface 22 form an angle of 90 degrees. The 2 nd reflector 20 directly faces the condenser lens 30, and the 1 st reflector 10 faces the condenser lens 30 only through the 2 nd reflector 20, but does not directly face the condenser lens 30. The mirror/transparent states of the 1 st reflector 10 and the 2 nd reflector 20 can be switched between forward and reverse by the operation of the smartphone 8. The positions of the 1 st reflector 10 and the 2 nd reflector 20 may be reversed. The 1 st reflector 10 and the 2 nd reflector 20 may be manufactured as an integral component or may be manufactured as separate components.
If instructed to switch to the front camera mode, the 1 st reflector 10 becomes a mirror state and the 2 nd reflector 20 becomes a transparent state. As shown in fig. 13, in this state, light emitted at each point of the front object and incident from the 1 st entrance port 1 is reflected on the entire surface of the 1 st reflecting surface 11 of the 1 st reflector 10, and the reflected light is transmitted through the 2 nd reflector 20 and condensed to a position corresponding to each point position of the object on the image sensor 40 via the condenser lens 30. The light incident from the 2 nd entrance port 2 on the rear side passes through the 2 nd reflector 20, and is absorbed by the wall on the front side of the 2 nd reflector 20 in the housing 9.
If instructed to switch to the rear camera mode, the 1 st reflector 10 becomes a transparent state and the 2 nd reflector 20 becomes a mirror state. As shown in fig. 14, in this state, light incident from the 2 nd incident port 2 is emitted at each point of the rear object, and is reflected on the entire surface of the 2 nd reflecting surface 22 of the 2 nd reflecting body 20, and the reflected light is condensed to a position corresponding to each point position of the object on the image sensor 40 via the condenser lens 30. The light incident from the 1 st entrance port 1 on the front side passes through the 1 st reflector 10, and is absorbed by the rear sidewall of the 1 st reflector 10 in the housing 9. According to embodiment 2, the same effects as those of embodiment 1 can be obtained.
In embodiment 2, the 1 st reflector 10 is not formed of a light control material, but may be formed of a simple reflective material having a constant reflectance, and the 2 nd reflector 20 may be formed of only a light control material. In the rear camera mode, the light reflected by the 2 nd reflecting surface 22 of the 2 nd reflector 20 enters the condenser lens 30 without passing through the 1 st reflector 10, as described above. The light reflected by the 1 st reflecting surface 11 of the 1 st reflector 10 is reflected by the 2 nd reflector 20 in a mirror state, and is absorbed by the front side wall of the 2 nd reflector 20 in the housing 9. Therefore, even if the 1 st reflector 10 is not a light adjusting material, no problem occurs in the operation. That is, in the case of embodiment 2, when the 1 st reflector 10 and the 2 nd reflector 20 are disposed vertically and the condenser lens 30 and the image sensor 40 are disposed on the lower side, the reflector on the side close to the condenser lens 30 and the image sensor 40 may be formed of a light control material. In embodiment 2, the positions of the 1 st reflector 10 and the 2 nd reflector 20 may be changed. In this case, the 1 st reflecting body 10 is formed of a dimming material. The 2 nd reflector 20 may be formed of a light modulating material or may be formed of a simple reflective material.
