It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As described above, while consumers have made higher demands on the imaging quality, the shooting range, and the dark-scene shooting effect of the image pickup apparatus, the demand for miniaturization (particularly, thickness in a certain dimension) of the image pickup apparatus is also increasing due to the slimness of electronic products. The application provides a camera device integrated with three groups of optical lens groups, which can have better camera scene adaptability without obviously increasing the thickness of the camera device.
Fig. 1 and 2 are schematic diagrams showing an image pickup apparatus according to an embodiment of the present application. Referring to fig. 1 and 2, the image pickup apparatus includes: a telephoto lens group A having an effective focal length fA(ii) a A wide angle lens group B having an effective focal length fB(ii) a And a super wide angle lens group C having a maximum half angle of view of more than 55 °. A telephoto lens group A, a wide angle lens group B, and a super wide angle lens group C disposed at the same side of the image pickup device and fA/fB>7. This applicationThe provided image pickup device can realize high-definition detail shooting through the telephoto lens group A, expand a still range capable of clearly imaging through the wide-angle lens group B matched with the telephoto lens group A, and shoot a panorama of a wider field angle through the ultra-wide-angle lens group C. The camera device that this kind is equipped with three optical lens group that this application provided can enough satisfy the miniaturized requirement of camera device, can promote again and shoot and experience. Meanwhile, the effective focal lengths of the telephoto lens group a and the wide-angle lens group B satisfy the above numerical range, so that the image pickup apparatus can have a sufficiently large zoom factor. This configuration can effectively ensure a depth of field that can be clearly imaged. In addition, adjust super wide angle lens group C and have suitable angle of vision and can avoid the aberration of marginal field of vision too big when improving camera device formation of image height, help keeping the high characteristics of camera device formation of image quality better to can have open field of vision scope and ensure that the user has good shooting effect to experience when having guaranteed effectively that camera device formation of image is felt.
As shown in fig. 1, the telephoto lens group a, the wide angle lens group B, and the ultra wide angle lens group C may be arranged in a vertical direction at one side of the image pickup apparatus. Further, as shown in fig. 2, the telephoto lens group a, the wide angle lens group B, and the ultra wide angle lens group C may be arranged in a horizontal direction on one side of the image pickup apparatus. The telephoto lens group A, the wide angle lens group B and the ultra-wide angle lens group C can respectively image an object. For example, the telephoto lens group a may be equipped with a first photosensitive chip paired with the telephoto lens group a, the wide angle lens group B may be equipped with a second photosensitive chip paired with the wide angle lens group B, and the ultra-wide angle lens group C may be equipped with a third photosensitive chip paired with the ultra-wide angle lens group C. The first photosensitive chip may be a black and white photosensitive chip, such as a mono (monochrome) chip. The black and white photosensitive chip can be used for sensing the light and shade intensity of the image. Further, the second and third photosensitive chips may each be a color photosensitive chip, such as an RGB (Red-Green-Blue) chip or an RGBW (Red-Green-Blue-White) chip. The color sensitive chip can be used for restoring the hue and the chroma.
In addition, images photographed by the telephoto lens group a, the wide angle lens group B, and the ultra-wide angle lens group C may be combined into a composite image, thereby simultaneously having characteristics of a large depth of field, high definition, and an ultra-wide angle. In addition, the matching of the photosensitive chips is combined, and a clear image with high contrast and high color fidelity can be obtained.
A telephoto lens group according to an embodiment of the present application may be a five-plate lens group. The telephoto lens group includes, in order from an object side to an image side: a tele group first lens having a focal power; a telephoto-group second lens having a negative focal power; a tele group third lens having a focal power; a tele group fourth lens having a positive focal power; and a telephoto group fifth lens having optical power. The long-focus lens group obtained according to the configuration can effectively reduce the spherical aberration, astigmatism and coma aberration of the lens group, and realize high-quality imaging quality.
As will be described in detail with reference to fig. 3 and 4 below, a telephoto lens group according to an embodiment of the present application may be a periscopic lens group. For the periscopic lens set, the optical path does not extend along a single direction. For example, the optical axis of the tele lens group may change by 90 ° in the direction behind the first lens passing through the tele group. By providing such a periscopic lens group, it is possible to increase the thickness of the lens group in the lens stacking direction without increasing the thickness of the lens group in the light incidence direction. Therefore, the periscopic lens group can well give consideration to miniaturization and long focal length, and the problem that the conventional long-focus lens group has a long size is avoided. According to the embodiment of the present application, the effective focal length fA of the telephoto lens group may satisfy: 18mm < fA <20 mm.
According to the embodiments of the present application, any two lenses of each of the telephoto, wide angle, and super wide angle lens groups have a gap therebetween. The arrangement of the gap can not only alleviate the deflection of the light rays between the lenses, but also avoid the damage caused by the collision between the adjacent lenses during the assembly.
The wide angle lens group according to an embodiment of the present application may be a six-lens group. The wide angle lens group may include, in order from an object side to an image side: a wide-angle group first lens having a positive power; a wide-angle group second lens having a focal power; a wide-angle group third lens having a focal power; a wide-angle group fourth lens having a positive refractive power; a wide-angle group fifth lens having a focal power; and a wide-angle group sixth lens having a negative power. The wide-angle lens group obtained according to the configuration can effectively reduce spherical aberration, astigmatism and coma of the lens group, and realize high-quality imaging quality.
According to the embodiment of the application, the effective focal length f of the wide-angle lens groupBAnd the entrance pupil diameter EPD of the wide-angle lens groupBCan satisfy the following conditions: f. ofB/EPDB<2.0. Accordingly, the wide-angle lens group can have a larger aperture to ensure that enough imaging light enters the optical system even when the shooting environment is dark, so that the image surface has enough brightness. Therefore, the imaging effect can be good under the dark scene shooting.
According to the embodiment of the present application, TTL is the distance from the object side surface of the first lens of the wide angle group to the imaging surface of the wide angle lens groupBA length ImgH semi-diagonal to an effective pixel region on an imaging surface of the wide angle lens groupBSatisfies the following conditions: TTL (transistor-transistor logic)B/ImgHB<1.5. With the above configuration, the optical lens group can have an imaging surface large enough to present more detailed information of the object under the condition that the wide angle lens group has a shorter length.
According to the embodiment of the present application, the effective focal length f1 of the first lens of the wide-angle groupBEffective focal length f6 of sixth lens of wide-angle groupBAnd effective focal length f4 of the fourth lens of the wide-angle groupBSatisfies the following conditions: 1.4<(f1B+f6B)/f4B<3.4. The parameter configuration of the wide-angle lens group can effectively balance spherical aberration, chromatic aberration and astigmatism generated by the three lenses, and the imaging quality is improved.
According to the embodiment of the present application, the radius of curvature R1 of the object side surface of the first lens of the wide-angle groupBRadius of curvature R2 of image side surface of first lens of wide-angle groupBRadius of curvature R3 of object side surface of second lens of wide-angle groupBAnd a radius of curvature R4 of an image-side surface of the second lens of the wide-angle groupBSatisfies the following conditions: 0.8<(R1B+R2B)/(R3B+R4B)<1.4, e.g. 0.94<(R1B+R2B)/(R3B+R4B)<1.30. The parameter configuration of the wide-angle lens group can effectively slow down the deflection of light rays in the first lens of the wide-angle group and the second lens of the wide-angle group, thereby avoiding strong total reflection ghost images generated due to overlarge deflection angles.
According to the embodiment of the present application, the radius of curvature R11 of the object-side surface of the sixth lens element of the wide-angle groupBRadius of curvature R12 of image side surface of sixth lens element of wide-angle groupBRadius of curvature R5 of object side surface of third lens of wide-angle groupBAnd radius of curvature R6 of image-side surface of the wide-angle group third lensBSatisfies the following conditions: 0.5<(R11B+R12B)/(R5B+R6B)<0.8. The above parameter configuration of the wide-Angle lens group can reduce the Chief Ray Angle of the light entering the imaging surface, thereby realizing matching with the CRA (chip Ray Angle) of the chip, simultaneously slowing down the deflection Angle of the light in the third lens of the wide-Angle group and the sixth lens of the wide-Angle group, and reducing the sensitivity of the two lenses.
According to the embodiment of the present application, the image-side surface of the fourth lens of the wide-angle group is convex and the image-side surface of the fifth lens of the wide-angle group is concave. The surface shapes of the image side surfaces of the fourth lens of the wide-angle group and the fifth lens of the wide-angle group in the wide-angle lens group are reasonably distributed, so that the coma aberration and astigmatism generated by the two lenses can be effectively balanced, and the high-quality imaging quality is realized.
According to an embodiment of the present application, the wide-angle group second lens has a positive power, the object-side surface of the wide-angle group second lens is convex, and the image-side surface of the wide-angle group second lens is concave. The power and the surface type of the second lens of the wide-angle group in the wide-angle lens group are reasonably configured, so that the deflection angle of light rays in the lens can be reduced, the sensitivity of the lens is reduced, the tolerance condition is relaxed, and the manufacturability of the lens is enhanced.

The effective focal lengths of the ultra-wide angle group third lens, the ultra-wide angle group fifth lens and the ultra-wide angle group first lens are reasonably configured, so that the deflection angles of light rays in the three lenses can be reduced, and astigmatism and field curvature generated by the three lenses can be balanced.
According to the embodiment of the application, the effective focal length f4 of the fourth lens of the ultra-wide angle groupCRadius of curvature R7 of object side surface of fourth lens of ultra-wide angle groupCAnd radius of curvature R8 of image side surface of fourth lens of ultra-wide angle groupCSatisfies the following conditions: 0.6<f4C/(R7C+R8C)<1.4, e.g. 0.66<f4C/(R7C+R8C)<1.31. By properly configuring the above parameters, the incident angle and refraction angle of light entering the fourth lens of the ultra-wide angle group can be reduced, thereby reducing the sensitivity of the lens to avoid too tight tolerance requirements.
According to the embodiment of the application, the curvature radius R11 of the object side surface of the sixth lens of the ultra-wide angle groupCRadius of curvature R12 of image side surface of sixth lens element of ultra-wide angle groupCRadius of curvature R9 of object side surface of fifth lens of ultra-wide angle groupCAnd radius of curvature R10 of image side surface of ultra-wide angle group fifth lensCSatisfies the following conditions: -1.0<(R11C+R12C)/(R9C+R10C)<-0.3. By reasonably configuring the parameters, the matching of the main light angle of the super wide angle lens group and the chip can be ensured, and stronger total reflection ghost images generated by overlarge light deflection angles can be avoided.
According to the embodiment of the application, at least four lenses of any one of the wide-angle lens group and the ultra-wide-angle lens group are made of plastic materials.
