    DETAILED DESCRIPTION OF THE INVENTION

    [0083] An adjustable shading module of an embodiment of the present invention is illustrated in FIG. 1 to FIG. 3 and includes an optical image capturing system 10, a base 12, and a shading cover 13, wherein the base 12 has an optical mounting portion 12a and a cover mounting portion 12b that are integrally formed as a monolithic unit. The base 12 could be made of, for example, Liquid Crystal Polyme (LCP) materials, or Polycarbonate plastic material and glass fiber, wherein the base made of Polycarbonate plastic material and glass fiber could have a better molding fluidity to avoid injection deformation and shrinkage problems, and could improve a toughness of the materials to avoid deformation after assembled.

    [0084] The optical mounting portion 12a has a chamber R1 and a through-hole H1 communicating with the chamber R1. The cover mounting portion 12b is located on a side of the optical mounting portion 12a. The optical image capturing system 10 includes an optical lens assembly 101, wherein the optical lens assembly 101 has an optical axis A and at least two lenses L arranged in order along the optical axis A from an object side to an image side. The optical lens assembly 101 is disposed in the chamber R1, and the object side of the optical lens assembly 101 faces towards the through-hole H1, wherein the optical axis A passes through the through-hole H1. The shading cover 13 is disposed on the cover mounting portion 12b and is movable on a moving path to close or open the through-hole H1, wherein the moving path is not parallel to the optical axis A. The optical lens assembly 101 satisfies: 1.0≤f/HEP≤10.0 and 0 deg <HAF≤150 deg, wherein f is a focal length of the optical lens assembly 101; HEP is an entrance pupil diameter of the optical lens assembly 101; HAF is a half of a maximum view angle of the optical lens assembly 101. The optical lens assembly 101 includes three to eight lenses with refractive power and satisfies: 0.1≤InTL/HOS≤0.95, wherein a distance on the optical axis A between the image plane and an object-side surface of one of the lenses that is the closest to the object side is denoted by HOS; a distance from the object-side surface of one of the lenses that is the closest to the object side to an image-side surface of one of the lenses that is the closest to the image side is denoted by InTL. The optical lens assembly 101 further includes an aperture and satisfies: 0.2≤InS/HOS≤1.1, wherein a distance on the optical axis A between the aperture and the image plane is denoted by InS.

    [0085] With the shading cover 13 that could move on the moving path to close or open the through-hole H1, the optical image capturing system 10 could be switched between an open state S1 and a closed state S2. Referring to FIG. 3, the shading cover 13 blocks ambient light from entering the optical image capturing system 10 through the through-hole H1 when the optical image capturing system 10 is in the closed state S2. Referring to FIG. 4, the shading cover 13 allows ambient light to enter the optical image capturing system 10 through the through-hole H1 when the optical image capturing system 10 is in the open state S1. In the current embodiment, the number of the shading cover 13 is one as an example. In practice, the number of the shading cover 13 could be more than one.

    [0086] The cover mounting portion 12b has a guiding groove 121 accompany with the moving path, thereby the shading cover 13 could be stably disposed in the guiding groove 121 and could move along the guiding groove 121 to be hard to disengaged from the base 12. Additionally, a forced portion 131 could be provided on a side of the shading cover 13 opposite to the through-hole H1, thereby the forced portion 131 could be pushed to move on the moving path. For instance, referring to FIG. 5, the forced portion 131 could be a recess recessed into a surface of the shading cover 13 opposite to the base 12, so that a user could put a finger into the recess to push the shading cover 13 to move on the moving path; alternatively, referring to FIG. 6, the forced portion 131 could be a projection protruding from a surface of the shading cover 13 opposite to the base 12 towards a direction away from the base 12, so that a user could move the shading cover 13 by pushing the projection, allowing the optical image capturing system 10 to easily switch between the open state and the closed state.

    [0087] In an embodiment of the present invention, the adjustable shading module 1 includes at least one driving device for driving the at least one shading cover to move on the moving path relative to the optical lens assembly 101, and the base has a driver mounting portion that is integrally formed with the optical mounting portion and the cover mounting portion. The driver mounting portion has at least one receiving space. The at least one driving device is disposed in the at least one receiving space. The at least one receiving space is adjacent to the chamber, wherein the at least one receiving space and the chamber are arranged along a reference axis not parallel to the optical axis A.

    [0088] Referring to FIG. 7, in an embodiment, the number of the at least one driving device is one as an example, and the number of the at least one receiving space is one as an example, and the reference axis X is perpendicular to the optical axis A as an example. The driving device includes an electromagnet 14 disposed in the receiving space R2, and the shading cover 13 includes a magnetic member 133, which is a magnet as an example, connected to a side of the shading cover 13 facing towards the receiving space R2, so that the electromagnet 14 generates a magnetic field based on a received current to repel or attract the magnetic member 133, thereby driving the shading cover 13 to displace.

    [0089] For instance, when the electromagnet 14 does not receive current, the shading cover 13 is in a position blocking ambient light from entering the optical image capturing system 10 through the through-hole H1 to make the optical image capturing system 10 be in the closed state S2, as shown in FIG. 7; while when the electromagnet 14 receives a first current and generates a magnetic field, the electromagnet attracts the magnetic member 133 to an end of the electromagnet 14, driving the shading cover 13 to move to a position allowing ambient light to enter the optical image capturing system 10 via the through-hole H1 to make the optical image capturing system 10 be in the open state S1, as shown in FIG. 8. Additionally, the optical image capturing system 10 could be switched from the open state S1 to the closed state S2 by providing the electromagnet 14 with a with a current opposite to the first current (i.e., opposite directions) to attract the magnetic member 133 to another end of the electromagnet 14, driving the shading cover 13 to move to the position shading the through-hole H1, and stopping provide current to keep the shading cover 13 at the position shading the through-hole H1.

    [0090] Referring to FIG. 9, in an embodiment, the number of the at least one driving device is one as an example, and the number of the at least one receiving space is one as an example. The driving device includes a motor 15 connected to the shading cover 13 to drive the shading cover 13 to move on the moving path relative to the optical lens assembly 101, wherein the motor 15 is connected to a threaded rod 16 and is disposed in the receiving space R2, and the shading cover 13 has a threaded section. The threaded rod 16 is connected to the shading cover 13 via the threaded section. The motor 15 could drive the threaded rod 16 to turn to drive the shading cover 13 to move between a position shown in FIG. 9 and a position shown in FIG. 10 to close or open the through-hole H1, allowing the optical image capturing system 10 to switch between the closed state S2 and the open state S1.

    [0091] In an embodiment, the at least one shading cover has at least one light-transmitting hole, wherein the at least one shading cover could move along the moving path to a position that the at least one light-transmitting hole communicates with the through-hole H1 to open the through-hole H1 or to a position that the at least one light-transmitting hole does not communicate with the through-hole H1 to close the through-hole H1. In an embodiment, the at least one shading cover has a plurality of light-transmitting holes, wherein the light-transmitting holes respectively have different diameters and are arranged on the at least one shading cover along the moving path. For instance, referring to FIG. 11, two light-transmitting holes 135 with different diameters are disposed on the shading cover 13. When the electromagnet 14 receives a first current and generates a magnetic field to attract the magnetic member 133 to an end of the electromagnet 14 to move the shading cover 13 to a position shown in FIG. 11, one of the light-transmitting holes 135 with a larger diameter communicates with the through-hole H1, allowing ambient light to enter the optical image capturing system 10 through one of the light-transmitting holes 135 with a larger diameter; while when the electromagnet 14 receives a current opposite to the first current (i.e., opposite directions) and generates a magnetic field, the magnetic member 133 is attracted to another end of the electromagnet 14 to move the shading cover 13 to a position shown in FIG. 12, and one of the light-transmitting holes 135 with a smaller diameter communicates with the through-hole H1, allowing ambient light to enter the optical image capturing system 10 through one of the light-transmitting holes 135 with a smaller diameter. In this way, an effect of switching the amount of input light of the optical image capturing system 10 could be achieved.

    [0092] In an embodiment, the at least one driving device includes a plurality of electromagnets arranged along the reference axis X, wherein the electromagnets generate a magnetic field based on a received current to repel or attract the magnetic member 133, thereby to drive the shading cover 13 to displace. For instance, referring to FIG. 13, the driving device includes two electromagnets, which are respectively a first electromagnet 141 and a second electromagnet 143 arranged along the reference axis X. When the first electromagnet 141 receives a current and the second electromagnet 143 does not receive current, the first electromagnet 141 attracts the magnetic member 133 to move the shading cover 13 to a position that the light-transmitting hole 135 communicates with the through-hole H1, while when the first electromagnet 141 does not receive current and the second electromagnet 143 receives a current, the second electromagnet 143 attracts the magnetic member 133 to move the shading cover 13 to a position that the shading cover 13 shades the through-hole H1, thereby allowing the optical image capturing system 10 to be switched between the open state S1 and the closed state S2.

    [0093] In the embodiment shown in FIG. 13, a direction of the magnetic field, which is generated by the first electromagnet 141 and the second electromagnet 143 after receiving a current, is substantially parallel to the optical axis A.

A direction of the magnetic field, which is generated by the first electromagnet 141, the second electromagnet 143, and the third electromagnet 145 after receiving a current, is substantially parallel to the reference axis X. By controlling a current direction inputted to the first electromagnet 141 and the second electromagnet 143 or a coil winding direction, an end of the first electromagnet 141 facing the second electromagnet 143 and an end of the second electromagnet 143 facing the first electromagnet 141 generate opposite polarities when inputs current to the first electromagnet 141 and the second electromagnet 143, thereby respectively attracting two ends of the magnetic member 133 with opposite polarities.

Similarly, by controlling a current direction inputted to the second electromagnet 143 and the third electromagnet 145 or a coil winding direction, an end of the second electromagnet 143 facing the third electromagnet 145 and an end of the third electromagnet 145 facing the second electromagnet 143 generate opposite polarities when inputs current to the second electromagnet 143 and the third electromagnet 145, thereby respectively attracting two ends of the magnetic member 133 with opposite polarities. In this way, the magnetic member 133 could be moved from the position between the first electromagnet 141 and the second electromagnet 143 to a position between the second electromagnet 143 and the third electromagnet 145, thereby moving the shading cover 13 to a position that the shading cover 13 shades the through-hole H1.

Each of the motors 15 is connected to a threaded rod 16. The motors 15 are respectively disposed in the first receiving space R21 and the second receiving space R22. The first shading cover 13′ and the second shading cover 13″ respectively have a threaded section and are respectively connected to one of the threaded rods 16 via the threaded sections. Each of the motors 15 could drive one of the threaded rods 16 to turn, thereby respectively drive the first shading cover 13′ and the first shading cover 13″ to move in between the positions shown in FIG. 17 to FIG. 19 to close, partially open, or open the through-hole H1, allowing the optical image capturing system 10 to switch in between the closed state S2, a partial-open state S3, and the open state S1.

Referring to FIG. 17 to FIG. 19, the first light-transmitting hole 137 and the second light-transmitting hole 139 respectively have a first projection surface P1 and a second projection surface P2 on a reference surface perpendicular to the optical axis A. When the first shading cover 13′ and the second shading cover 13″ are located at the closed position, the first projection surface P1 does not overlap with the second projection surface P2. When the first shading cover 13′ and the second shading cover 13″ are located at the partial-open position, the first projection surface P1 partially overlaps with the second projection surface P2. When the first shading cover 13′ and the second shading cover 13″ are located at the open position, the first projection surface P1 and the second projection surface P2 completely overlap. In this way, the first shading cover 13′ and the second shading cover 13″ shade the through-hole H1 when the first shading cover 13′ and the second shading cover 13″ are located at the closed position, allowing the optical image capturing system 10 to be in the closed state S2; the first shading cover 13′ and the second shading cover 13″ shades a part of the through-hole H1 when the first shading cover 13′ and the second shading cover 13″ are located at the partial-open position, allowing the optical image capturing system 10 to be in the partial-open state S3; the first light-transmitting hole 137 of the first shading cover 13′ and the second light-transmitting hole 139 of the second shading cover 13″ completely communicate with the through-hole H1 when the first shading cover 13′ and the second shading cover 13″ are located at the open position, allowing the optical image capturing system 10 to be in the open state S1.

    Second Optical Embodiment

    [0195] Referring to FIG. 26A, a schematic diagram of an optical image capturing system 20 according to a second optical embodiment of the present invention. Referring to FIG. 26B, curve diagrams of longitudinal spherical aberration, astigmatic field curves, and distortion in order from left to right according to the second optical embodiment of the present invention.

    [0196] As shown in FIG. 26A, the optical image capturing system 20 of the second optical embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 210, a second lens 220, a third lens 230, an aperture 200, a fourth lens 240, a fifth lens 250, a sixth lens 260, a seven lens 270, an infrared rays filter 280, an image plane 290, and an image sensor 292.

    [0197] The first lens 210 has negative refractive power and is made of glass. An object-side surface 212 thereof, which faces the object side, is a convex spherical surface, and an image-side surface 214 thereof, which faces the image side, is a concave spherical surface.

    [0198] The second lens 220 has negative refractive power and is made of glass. An object-side surface 222 thereof, which faces the object side, is a concave spherical surface, and an image-side surface 224 thereof, which faces the image side, is a convex spherical surface.

    [0199] The third lens 230 has positive refractive power and is made of glass. An object-side surface 232, which faces the object side, is a convex spherical surface, and an image-side surface 234, which faces the image side, is a convex spherical surface.

    [0200] The fourth lens 240 has positive refractive power and is made of glass. An object-side surface 242, which faces the object side, is a convex spherical surface, and an image-side surface 244, which faces the image side, is a convex spherical surface.

    [0201] The fifth lens 250 has positive refractive power and is made of glass. An object-side surface 252, which faces the object side, is a convex spherical surface, and an image-side surface 254, which faces the image side, is a convex spherical surface.

    [0202] The sixth lens 260 has negative refractive power and is made of glass. An object-side surface 262, which faces the object side, is a concave spherical surface, and an image-side surface 264, which faces the image side, is a concave spherical surface. Whereby, incident angle of each field of view for the sixth lens 260 could be effectively adjusted to improve aberration.

    [0203] The seventh lens 270 has positive refractive power and is made of glass. An object-side surface 272, which faces the object side, is a convex spherical surface, and an image-side surface 274, which faces the image side, is a convex spherical surface. It may help to shorten the back focal length to keep small in size and reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

    [0204] The infrared rays filter 280 is made of glass and is disposed between the seventh lens 270 and the image plane 290. The infrared rays filter 280 gives no contribution to the focal length of the optical image capturing system 20.

    [0205] The parameters of the lenses of the second optical embodiment are listed in Table 3 and Table 4.

    [0237] Referring to FIG. 29A, a schematic diagram of an optical image capturing system 50 according to a fifth optical embodiment of the present invention. Referring to FIG. 29B, curve diagrams of longitudinal spherical aberration, astigmatic field curves, and distortion in order from left to right according to the fifth optical embodiment of the present invention. As shown in FIG. 29A, an optical image capturing system 50 of the fifth embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 500, a first lens 510, a second lens 520, a third lens 530, a fourth lens 540, an infrared rays filter 580, an image plane 590, and an image sensor 592.

    [0238] The first lens 510 has positive refractive power and is made of plastic. An object-side surface 512, which faces the object side, is a convex aspheric surface, and an image-side surface 514, which faces the image side, is a convex aspheric surface. The object-side surface 512 has an inflection point.

    [0239] The second lens 520 has negative refractive power and is made of plastic. An object-side surface 522 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 524 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 522 has two inflection points, and the image-side surface 524 has an inflection point.

    [0240] The third lens 530 has positive refractive power and is made of plastic. An object-side surface 532, which faces the object side, is a concave aspheric surface, and an image-side surface 534, which faces the image side, is a convex aspheric surface. The object-side surface 532 has three inflection points, and the image-side surface 534 has an inflection point.

    [0241] The fourth lens 540 has negative refractive power and is made of plastic. An object-side surface 542, which faces the object side, is a concave aspheric surface, and an image-side surface 544, which faces the image side, is a concave aspheric surface. The object-side surface 542 has three inflection points, and the image-side surface 544 has an inflection point.

    [0242] The infrared rays filter 580 is made of glass and is disposed between the fourth lens 540 and the image plane 590. The infrared rays filter 580 gives no contribution to the focal length of the optical image capturing system 50.

Referring to FIG. 30B, curve diagrams of longitudinal spherical aberration, astigmatic field curves, and distortion in order from left to right according to the sixth optical embodiment of the present invention.

    [0250] As shown in FIG. 30A, the optical image capturing system 60 of the sixth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 610, an aperture 600, a second lens 620, a third lens 630, an infrared rays filter 680, an image plane 690, and an image sensor 692.

    [0251] The first lens 610 has positive refractive power and is made of plastic. An object-side surface 612, which faces the object side, is a convex aspheric surface, and an image-side surface 614, which faces the image side, is a concave aspheric surface.

    [0252] The second lens 620 has negative refractive power and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 624 has an inflection point.

    [0253] The third lens 630 has positive refractive power and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a concave aspheric surface. The object-side surface 632 has two inflection points, and the image-side surface 634 has an inflection point.

    [0254] The infrared rays filter 680 is made of glass and is disposed between the third lens 630 and the image plane 690. The infrared rays filter 680 gives no contribution to the focal length of the optical image capturing system 60.
