Description

IMAGING LENS ASSEMBLY, CAMERA MODULE AND IMAGING DEVICE TECHNICAL FIELD
The present disclosure relates to an imaging lens assembly, a camera module, and an imaging device, and particularly to an imaging lens assembly, a camera module, and an imaging device that are small and enable good optical performance.
BACKGROUND
In recent years, portable imaging devices such as mobile phones and digital cameras are being widely used. With the recent miniaturization of imaging devices, an imaging lens assembly mounted on such imaging devices also requires downsizing.
In the imaging device, an imaging assembly having a large aperture (i.e., diameter) that can capture brighter images is required in order to avoid decreased sensitivity or increased noise of imaging elements due to the narrowing of the pitch of a cell.
However, if the total length of the imaging lens assembly having the large aperture is shortened to reduce the size of the imaging lens assembly, the amount of peripheral light (i.e., amount of light at the edge of the imaging lens assembly) will decrease.
Therefore, improvement of the conventional imaging lens assembly is desirable from the viewpoint of inhibiting decrease in the amount of peripheral light.
SUMMARY
The present disclosure aims to solve at least one of the technical problems mentioned above. Accordingly, the present disclosure needs to provide an imaging lens, a camera module and an imaging device.
In accordance with the present disclosure, an imaging lens assembly, includes, in order from an object side:

a fourth lens;
a fifth lens;

an eighth lens having a negative refractive power with a concave surface facing an image side, the imaging lens assembly being configured so that:
((m_fL_r3_si) – (m_fL_r2_si) ) /2 × (l_fL_r5_si) × π> 0.145,
Fno < 1.8, and
HFOV > 38.5°,
where (m_fL_r2_si) is a first direction cosine formed in a tangential direction by a first off-axis ray which is located, in an off-axis ray bundle, at an end of an off-axis side in the tangential direction, the off-axis ray bundle being imaged within an image circle which covers an effective pixel area on an imaging surface,
(m_fL_r3_si) is a second direction cosine formed in the tangential direction by a second off-axis ray which is located, in the off-axis ray bundle, at an end of an optical axis side in the tangential direction,
(l_fL_r5_si) is a third direction cosine formed in a sagittal direction by a third off-axis ray which is located, in the off-axis ray bundle, at an end of the sagittal direction,

DETAILED DESCRIPTION
Embodiments of the present disclosure will be described in detail and examples of the embodiments will be illustrated in the accompanying drawings. The same or similar elements, and elements having same or similar functions, are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to the drawings are explanatory and aim to illustrate the present disclosure but shall not be construed to limit the present disclosure.
<Outline of the disclosure>
First, an outline of the present disclosure will be described. An imaging device 1 to which the present disclosure applies is configured as shown in FIG. 1, for example. In the figure, dash–dotted lines represent optical axes of the imaging device 1 (hereinafter the same applies) .
The imaging device 1 shown in FIG. 1 includes a camera module 11, a housing 12 which stores the camera module 11, and an image processing unit 13. The camera module 11 includes an imaging lens assembly 21, an optical filter 22, and an image sensor 23.
The imaging lens assembly 21, for example, includes eight lenses and an aperture stop 3. The eight lenses consist of first to eighth lenses disposed in order from an object side. The aperture stop 3 is disposed on an object side with respect to a surface on an image side of the first lens. The imaging lens assembly 21 images incident light incident from the object side on an imaging surface S. For example, the eight lenses are held in a barrel and are configured to be integrally movable along the optical axis by an autofocus mechanism such as a stepping motor or a voice coil motor. Since the imaging lens assembly 21 includes the eight lenses, a large size image sensor 23 can be effectively applied. By using the large image sensor 23, image quality of a captured image can be improved. In addition, by including the eight lenses, the imaging lens assembly 21 can effectively correct various aberrations. Since the aperture stop 3 is disposed on the object side with respect to the surface on the image side of the first lens, an aperture (i.e., a diameter) of the imaging lens assembly 21 can be increased without increasing the total length of the imaging lens assembly 21. By increasing the aperture of the imaging lens assembly 21, light from the object can be efficiently captured to obtain a bright image.
The image sensor 23 is, for example, a solid-state image sensor, such as CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charge Coupled Device) . The image sensor 23 has the imaging surface S which is an imaging plane of the imaging lens assembly 21. The image sensor 23 is mounted on a surface of a substrate 24.
The image sensor 23 receives incident light from the subject (object side) via the imaging lens assembly 21 and the optical filter 22, photoelectrically converts the light, and outputs an image data, obtained by photoelectric conversion of the light, to a subsequent stage.
The image processing unit 13 is connected to the image sensor 23. The image data output from the image sensor 23 is input to the image processing unit 13. The image processing unit 13 performs noise reduction processing on the input image data. The noise reduction processing is, for example, increasing brightness (e.g., luminance value) of a periphery of an image and reducing noise revealed in the periphery of the image, the revealed noise being uncovered by increasing the brightness of the periphery of the image. The image processing unit 13 may be, for example, a processor which reads and executes a program stored in a memory. By performing the noise reduction processing, the image quality of the captured image can be improved.
The optical filter 22 is disposed between the imaging lens assembly 21 and the image sensor 23. The optical filter 22 may be, for example, an infrared cut filter (IRCF) which cuts infrared light from light which is incident from the imaging lens assembly 21.
The first lens may have a positive refractive power with a convex surface facing the object side. The second lens may have a negative refractive power. The third lens may have a positive refractive power. The eighth lens may have a negative refractive power with a concave surface facing the image side. By having this combination of refractive powers, the imaging lens assembly 21 can further effectively correct various aberrations.
The eighth lens which is the most image side disposed lens may have an aspherical shape having an inflection point. A back focus of the imaging lens assembly 21 can be shortened when the eighth lens has the aspherical shape having the inflection point. By shortening the back focus, the total length of the imaging lens assembly 21 can be shortened. In view of shortening the back focus, it is preferable that a surface on the image side of the eighth lens have the aspheric shape having the inflection point.
In view of molding the lens, it is preferable that an aspheric lens constituting the imaging lens assembly 21, in particular a lens of aspheric shape having an inflection point, be formed of plastic material. In addition, among the lenses which constitute the imaging lens assembly 21, a lens having a size equal to or smaller than a specific size may be a lens formed of a plastic material, and a lens larger than the specific size may be a lens formed of a glass material. This is because it is difficult to form an aspheric lens or a relatively small lens using a material other than plastic.
If the amount of peripheral light is low, a ratio of noise to signal in the periphery of the image before performing the noise reduction processing will be large. This makes it difficult to sufficiently reduce the noise even after performing the noise reduction processing. In particular, if the amount of peripheral light is low during shooting at night, it is difficult to obtain a captured image in which the image quality is good, and the noise is sufficiently reduced.
In contrast, the camera module 11 according to the present disclosure can effectively inhibit the decrease in the amount of the peripheral light by satisfying the following inequality (1) :
( (m_fL_r3_si) – (m_fL_r2_si) ) /2 × (l_fL_r5_si) × π> 0.145   (1)
In the inequality (1) , (m_fL_r2_si) is a first direction cosine formed in a tangential direction by a first off-axis ray (i.e., a marginal upper ray) which is located, in an off-axis ray bundle, at an end of an off-axis side in the tangential direction, the off-axis ray bundle (i.e., a pencil of rays deviated from the optical axis) being imaged within an image circle which covers an effective pixel area on an imaging surface S (hereinafter the same applies) .
(m_fL_r3_si) is a second direction cosine formed in the tangential direction by a second off-axis ray (i.e., a marginal lower ray) which is located, in the off-axis ray bundle, at an end of the optical axis side in the tangential direction (hereinafter the same applies) .
(l_fL_r5_si) is a third direction cosine formed in a sagittal direction by a third off-axis ray (i.e., a marginal ray) which is located, in the off-axis ray bundle, at an end of the sagittal direction (hereinafter the same applies) .
The tangential direction is a direction which is perpendicular to the optical axis and is parallel to a tangential plane, the tangential plane including the optical axis and a principal ray (i.e., a main ray) in the off-axis ray bundle (hereinafter the same applies) . The tangential direction can also be referred to as a radial direction. The sagittal direction is a direction which is perpendicular to the optical axis and the tangential direction (hereinafter the same applies) .
The direction cosine in the tangential direction may be positive in a direction from the peripheral side to the optical axis side (i.e., + tangential direction) and may be negative in a direction from the optical axis side to the peripheral side (i.e., -tangential direction) . The direction cosine in the sagittal direction may be positive in a negative direction of an X coordinate (i.e., + sagittal direction) , when XYZ coordinates of the imaging lens assembly are defined as shown in FIG. 2. In the XYZ coordinates of the imaging lens assembly 21, a direction from the object side to the imaging surface S side along the optical axis is a positive direction of the Z coordinate (+Z) . A direction from the optical axis to the peripheral side along the tangential plane is a positive direction of the Y coordinate (+Y) . A direction toward the back of the paper in FIG. 2 is a positive direction of the X coordinate (+X) .
The left side of the inequality (1) corresponds to a solid angle projected area which is obtained by projecting a solid angle onto the imaging surface S, the solid angle being formed by the off-axis ray bundle and having its apex at the imaging point of the off-axis ray bundle.
FIG. 2 shows an enlarged view A of a cross-section of the camera module 11 cut in the tangential plane in the area around the image sensor 23. FIG. 2 also shows a rear-view B of the solid angle projected area PA viewed from the back of the imaging surface S, the solid angle projected area PA being formed by the off-axis ray bundle 200. In the example shown in FIG. 2, the off-axis ray bundle 200 is imaged on the imaging surface S at the imaging point Sp which is located within a range of the image circle and is away from the optical axis. The off-axis ray bundle 200 includes the first off-axis ray 201, the second off-axis ray 202, the third off-axis ray 203, and the principal ray 204. In addition to these rays 201-204, the off-axis ray bundle 200 includes numerous rays which are not shown in FIG. 2.
In the example shown in FIG. 2, the first off-axis ray 201 is located in the off-axis ray bundle 200 at the end of the off-axis side in the tangential direction (TD) (i.e., an end in a -tangential direction) . The second off-axis ray 202 is located in the off-axis ray bundle 200 at the end of the optical axis side in the tangential direction (TD) (i.e., an end in a + tangential direction) . The third off-axis ray 203 is located in the off-axis ray bundle 200 at the end of the sagittal direction (SD) (i.e., an end in a + sagittal direction) .
As shown in FIG. 2, the first direction cosine (m_fL_r2_si) corresponds to a length of a tangential direction component of a part of the first off-axis ray 201, the part of the first off-axis ray 201 being in a range from the imaging point Sp to a point of a unit length. The second direction cosine (m_fL_r3_si) corresponds to a length of a tangential direction component of a part of the second off-axis ray 202, the part of the second off-axis ray 202 being in a range from the imaging point Sp to a point of the unit length. The third direction cosine (l_fL_r5_si) corresponds to a length of a sagittal direction component of a part of the third off-axis ray 203, the part of the third off-axis ray 203 being in a range from the imaging point Sp to a point of the unit length. The solid angle projected area PA of the off-axis ray bundle 200 corresponds to an area formed by projecting the solid angle SA onto the imaging surface S. As can be seen from FIG. 2, the left side of the inequality (1) : ( (m_fL_r3_si) - (m_fL_r2_si) ) /2 × (l_fL_r5_si) × π corresponds to the solid angle projected area PA having an ellipsoidal shape.
As shown in FIG. 3, in a study for the present disclosure, it was newly found that a relative illumination RI (i.e., a ratio of an amount of the peripheral light to an amount of a central light) (vertical axis in FIG. 3) is approximately proportional to the solid angle projected area PA (horizontal axis in FIG. 3) . Based on this new finding, the present disclosure defines the inequality (1) for obtaining a large amount of the peripheral light.
If the value of ( (m_fL_r3_si) - (m_fL_r2_si) ) /2 × (l_fL_r5_si) × π falls below the lower limit of the inequality (1) , the amount of the peripheral light is small and the brightness of the captured image is uneven. On top of that, noise may increase and image quality may be impaired when correction of the brightness at the periphery of the image is performed during, for example, shooting in dark places.
The inequality (1) can be satisfied by appropriately adjusting the parameters of each lens (radius of curvature, distance between surfaces, refractive index, focal length, aspheric coefficient, etc. ) .
According to the present disclosure, by satisfying inequality (1) , the amount of the peripheral light can be increased. By increasing the amount of the peripheral light, the ratio of noise to signal in the periphery of the image before performing the noise reduction processing can be reduced. This makes it possible to have the noise sufficiently reduced as a result of performing the noise reduction processing. As a result, image quality of the captured image can be improved.
Further, the camera module 11 can more effectively improve image quality when the camera module 11 satisfies the following inequality (2) :

If the value of Fno exceeds the upper limit of the inequality (2) , an amount of light irradiated to the imaging surface S is decreased, and thus the captured image is dark and image quality during shooting in a dark place is deteriorated. In order to improve image quality, it is preferable that Fno be equal to or less than 1.6.

In the inequality (3) , HFOV is a half angle of view (hereinafter the same applies) .
If the value of HFOV falls below the lower limit of the inequality (3) , a focal length of the imaging lens assembly 21 is too large, and thus the total length of the imaging lens assembly 21 is too large.
Further, the camera module 11 can effectively improve optical performance when the camera module 11 satisfies the following inequality (4) :

If the value of F1 /FL exceeds the upper limit of the inequality (4) , a positive refractive power of the first lens decreases to impair convergence ability of light, and thus it is difficult to obtain a bright captured image. In order to improve optical performance, it is more preferable that the value of F1 /FL be equal to or less than 1.6.

If the value of F L1-L5 /FL exceeds the upper limit of the inequality (5) , a positive refractive power of a lens group on the object side is small, and thus it is difficult to correct on-axis aberrations (i.e., spherical aberration and chromatic aberration) . In order to improve optical performance, it is more preferable that the value of F L1-L5 /FL be equal to or less than 1.6.

If the value of ∑ |FL /F (i) | falls below the lower limit of the inequality (6) , the refractive power of each lens is too small, and thus it is difficult to correct aberrations and the total length of the imaging lens assembly 21 increases. If the value of ∑ |FL /F (i) | exceeds the upper limit of the inequality (6) , the refractive power of each lens is too large, and thus sensitivity to manufacturing errors of the imaging lens assembly 21 increases which causes a decrease in yield. In order to improve optical performance and manufacturability of the imaging lens assembly 21, it is more preferable that the value of ∑ |FL /F (i) | be between 3.0 or more and 6.0 or less.

If the value of ∑ |1 /Ri| exceeds the upper limit of the inequality (7) , the refractive power of each lens is too large, and thus higher order aberrations occur and manufacturing error sensitivity  of the imaging lens assembly 21 increases which causes a decrease in yield. In order to improve optical performance and manufacturability of the imaging lens assembly 21, it is more preferable that the value of ∑ |1 /Ri| be equal to or less than 2.0.

If the value of TTL /D L1-L5 falls below the lower limit of the inequality (8) , a total length of the lens group on the object side is too large, and thus it is difficult to correct aberrations on the periphery of the image by using a lens group on the image side. If the value of TTL /D L1-L5 exceeds the upper limit of the inequality (8) , the positive refractive power of the lens group on the object side is too large and thus it is difficult to correct axial aberrations and sensitivity to manufacturing errors in the imaging lens assembly 21 increases which causes a decrease in yield. In order to improve optical performance and manufacturability of the imaging lens assembly 21, it is preferable that the value of TTL /D L1-L5 be between 1.5 or more and 2.5 or less.

If the value of R3 /R4 falls below the lower limit of the inequality (9) , a negative refractive power of the second lens is small, and thus divergence of light rays in the periphery is insufficient which makes it difficult to correct aberrations, and the total length of the imaging lens assembly 21 is too large. If the value of R3 /R4 exceeds the upper limit of the inequality (9) , the curvature of the surface on the image side of the second lens is too large, and thus higher order aberrations occur and Fresnel reflections occur which decreases the amount of the peripheral light. In order to miniaturize the imaging lens assembly 21 and to improve optical performance, it is more preferable that the value of R3 /R4 be between 1.0 or more and 2.5 or less.

If the value of R12 /R11 falls below the lower limit of the inequality (10) , the sixth lens is not meniscus-shaped, and thus a refraction angle of an on-axis ray is large which makes it difficult to correct aberrations. It is more preferable that the value of R12 /R11 be equal to or greater than 0.5.

(n = an integer equal to or greater than 3) .
In the formula (18) , Z is a depth of the aspheric surface. C is a paraxial curvature which is equal to 1 /R. h is a distance from the optical axis to a lens surface. K is a cone coefficient (second-order aspheric coefficient) . An is an nth-order aspheric coefficient.
[First example]
A first example in which specific numerical values are applied to the camera module 11 shown in FIG. 4 will be described.
In the first example, as shown in FIG. 4, the imaging lens assembly 21 includes, in order from the object side toward the image side, a first lens L1 having a positive refractive power with a convex surface facing the object side, a second lens L2 having a negative refractive power, a third lens L3 having a positive refractive power, a fourth lens L4 having a negative refractive power, a fifth lens L5 having a positive refractive power with a convex surface facing the image side, a sixth lens L6 having a positive refractive power, a seventh lens L7 having a positive refractive power, and an eighth lens having a negative refractive power with concave surfaces facing the object side and the image side.
The aperture stop 3 is disposed on the image side with respect to the apex of the first surface of the first lens L1 and on the object side with respect to the second surface of the first lens L1.
Table 1 shows, as lens data of the first example, a radius of curvature R (mm) , a surface distance D (mm) , a refractive index Nd and an Abbe number νd. Table 2 shows a focal length FL (mm) of the imaging lens assembly 21, an F number Fno, an angle of view (°) , a total track length TTL (mm) which is obtained when an object point is taken at infinity, and a size of a sensor (mm 2) . Table 3 shows values of the focal lengths of the first lens L1 to the eighth lens L8. Table 4 shows values corresponding to the conditional expressions shown in the inequalities (1) to (17) . Table 5 shows a radius of each curvature of the first lens L1 to the eighth lens L8, a cone coefficient K and the third to thirtieth aspherical coefficient of each side of each lens.

Each aberration of the above first example is shown in FIG. 5. FIG. 5 shows, as examples of aberrations, spherical aberration, astigmatism (field curvature) and distortion. Each of these aberration diagrams shows aberrations with d-line (587.56 nm) as a reference wavelength. In the spherical aberration diagram, aberrations with respect to g-line (435.84 nm) and C-line (656.27 nm) are also shown. In the graph showing astigmatism, “S” indicates a value of aberration on a sagittal image surface and “T” indicates a value of aberration on a tangential image surface. “IMG HT” indicates an image height. The same applies to aberration diagrams in other examples.
As can be seen from the aberration diagrams mentioned above, it is clear that the camera module 11 in the first example can satisfactorily correct various aberrations for superior optical performance, despite being small in size.
[Second Example]
Next, a second example, in which specific numerical values are applied to the camera module 11 shown in FIG. 6, will be described.
The lens parameters corresponding to those in the first example are shown in Tables 6 to 10.

Aberrations in the third example are shown in FIG. 9. According to the third example, by making the lens parameters different from those of the first example, the degree of freedom in designing the camera module 11 according to the present disclosure can be further increased while obtaining the same effects as in the first example.
[Fourth Example]
Next, a fourth example, in which specific numerical values are applied to the camera module 11 shown in FIG. 10, will be described.
Unlike the first to third examples, in the fourth example, the fourth lens L4 has a positive refractive power and the sixth lens L6 has a negative refractive power.
The lens parameters corresponding to those in the first example are shown in Tables 16 to 20.

Aberrations in the fourth example are shown in FIG. 11. According to the fourth example, by making the lens parameters different from those of the first example, the degree of freedom in designing the camera module 11 according to the present disclosure can be further increased while obtaining the same effects as in the first example.
[Fifth Example]
Next, a fifth example, in which specific numerical values are applied to the camera module 11 shown in FIG. 12, will be described.
Unlike the first to third examples, in the fifth example, the sixth lens L6 has a negative refractive power.
The lens parameters corresponding to those in the first example are shown in Tables 21 to 25.

Aberrations in the sixth example are shown in FIG. 15. According to the sixth example, by making the lens parameters different from those of the first example, the degree of freedom in designing the camera module 11 according to the present disclosure can be further increased while obtaining the same effects as in the first example.
[Seventh Example]
Next, a seventh example, in which specific numerical values are applied to the camera module 11 shown in FIG. 16, will be described.
Unlike the first to sixth examples, in the seventh example, the fifth lens L5 has a negative refractive power.
The lens parameters corresponding to those in the first example are shown in Tables 31 to 35.

Aberrations in the seventh example are shown in FIG. 17. According to the seventh example, by making the lens parameters different from those of the first example, the degree of freedom in designing the camera module 11 according to the present disclosure can be further increased while obtaining the same effects as in the first example.
[Eighth Example]
Next, an eighth example, in which specific numerical values are applied to the camera module 11 shown in FIG. 18, will be described.
Unlike the first to seventh examples, in the eighth example, the seventh lens L7 has a negative refractive power.
The lens parameters corresponding to those in the first example are shown in Tables 36 to 40.

Aberrations in the eighth example are shown in FIG. 19. According to the eighth example, by making the lens parameters different from those of the first example, the degree of freedom in designing the camera module 11 according to the present disclosure can be further increased while obtaining the same effects as in the first example.
In the description of embodiments of the present disclosure, it is to be understood that terms such as "central" , "longitudinal" , "transverse" , "length" , "width" , "thickness" , "upper" , "lower" , "front" , "rear" , "back" , "left" , "right" , "vertical" , "horizontal" , "top" , "bottom" , "inner" , "outer" , "clockwise" and "counterclockwise" should be construed to refer to the orientation or the position as described or as shown in the drawings in discussion. These relative terms are only used to simplify the description of the present disclosure, and do not indicate or imply that the device or element referred to must have a particular orientation, or must be constructed or operated in a particular orientation. Thus, these terms cannot be constructed to limit the present disclosure.
In addition, terms such as "first" and "second" are used herein for purposes of description and are not intended to indicate or imply relative importance or significance or to imply the number of indicated technical features. Thus, a feature defined as "first" and "second" may comprise one or more of this feature. In the description of the present disclosure, "a plurality of" means “two or more than two” , unless otherwise specified.
In the description of embodiments of the present disclosure, unless specified or limited otherwise, the terms "mounted" , "connected" , "coupled" and the like are used broadly, and may be, for example, fixed connections, detachable connections, or integral connections; may also be mechanical or electrical connections; may also be direct connections or indirect connections via intervening structures; may also be inner communications of two elements which can be understood by those skilled in the art according to specific situations.
In the embodiments of the present disclosure, unless specified or limited otherwise, a structure in which a first feature is "on" or "below" a second feature may include an embodiment in which the first feature is in direct contact with the second feature, and may also include an  embodiment in which the first feature and the second feature are not in direct contact with each other, but are in contact via an additional feature formed therebetween. Furthermore, a first feature "on" , "above" or "on top of" a second feature may include an embodiment in which the first feature is orthogonally or obliquely "on" , "above" or "on top of" the second feature, or just means that the first feature is at a height higher than that of the second feature; while a first feature "below" , "under" or "on bottom of" a second feature may include an embodiment in which the first feature is orthogonally or obliquely "below" , "under" or "on bottom of" the second feature, or just means that the first feature is at a height lower than that of the second feature.
Various embodiments and examples are provided in the above description to implement different structures of the present disclosure. In order to simplify the present disclosure, certain elements and settings are described above. However, these elements and settings are only by way of example and are not intended to limit the present disclosure. In addition, reference numbers and/or reference letters may be repeated in different examples in the present disclosure. This repetition is for the purpose of simplification and clarity and does not refer to relations between different embodiments and/or settings. Furthermore, examples of different processes and materials are provided in the present disclosure. However, it should be appreciated by those skilled in the art that other processes and/or materials may also be applied.
Reference throughout this specification to "an embodiment" , "some embodiments" , "an exemplary embodiment" , "an example" , "a specific example" or "some examples" means that a particular feature, structure, material, or characteristics described in connection with the embodiment or example is included in at least one embodiment or example of the present disclosure. Thus, the appearance of the above phrases throughout this specification does not necessarily refer to the same embodiment or example of the present disclosure. Furthermore, the particular features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
