Description

Camera optical lens, camera module and terminal

Technical Field

The embodiments of the present application relate to the field of optical lenses, and more particularly, to a photographing optical lens, a camera module, and a terminal.

Background

With the development of the intelligent terminal technology and the demand of diversified consumers, the camera function has become an important feature of the intelligent terminal and a main index for evaluating the performance of the intelligent terminal, and the trend of the intelligent terminal towards a light, thin, short and small appearance is added, so that the market demand for a small camera lens with good imaging quality is gradually increased.

In order to obtain better imaging quality, the traditional shooting optical lens mostly adopts a four-piece or five-piece lens structure, and as the pixels of the photosensitive elements are continuously reduced, six-piece and seven-piece lens structures begin to appear, but the optical characteristics are not obviously improved.

The F-number of the diaphragm is a key index directly influencing the core function of the camera lens, and the F-number of the diaphragm of the future lens is smaller and smaller along with the technical development. With the thickness of the intelligent terminal becoming thinner and thinner, the conventional lens imaging structure is difficult to achieve a small Total Track Length (TTL) while reducing the F value of the aperture so as to meet the requirement of light weight and thinness.

Therefore, it is necessary to design an image pickup optical lens that can satisfy the requirements of a large aperture and a small total optical length TTL while achieving high imaging performance.

In addition, this application has still provided the camera module who has used this optical lens of making a video recording to and the terminal of having used this camera module.

In a first aspect, an imaging optical lens is provided, in order from an object side to an image side, comprising: the lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens.

Each lens of the image pickup optical lens satisfies the following relational expression:

wherein f is the focal length of the imaging optical lens. And TTL is the total optical length of the shooting optical lens. n1 is a refractive index of the first lens, v1 is an abbe number of the first lens, v2 is an abbe number of the second lens, v3 is an abbe number of the third lens, and v4 is an abbe number of the fourth lens.

When the focal length, the total optical length, the refractive index of the constituent lenses and the abbe number of the photographic optical lens in the embodiment of the application satisfy the above relational expression, the photographic optical lens can satisfy the requirements of a large aperture or an ultra-large aperture and a small total optical length while obtaining high imaging performance.

Specifically, the above relation defines a ratio range of the focal length to the total optical length of the imaging optical lens, which is advantageous for scaling when the optical system architecture is the same.

It should be understood that the above-mentioned "respective lenses of the image pickup optical lens" refer to lenses constituting the image pickup optical lens, and in the embodiment of the present application, the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens.

The refractive index of the first lens is defined in the relation, the selectable range of the refractive index of the first lens is large, a thin glass lens with good performance can be obtained more easily, and the total optical length can be reduced.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

For convenience of understanding, technical terms related to the present application are explained and described below.

Focal length (focal length), also known as focal length, is a measure of the concentration or divergence of light in an optical system, and refers to the perpendicular distance from the optical center of a lens or lens group to the focal plane when an infinite scene is imaged sharply at the focal plane through the lens or lens group. From a practical point of view it can be understood as the distance from the lens center to the film plane. For a fixed-focus lens, the position of the optical center is fixed and unchanged; for a zoom lens, a change in the optical center of the lens results in a change in the focal length of the lens.

The aperture, which is a device for controlling the amount of light transmitted through the lens and into the light-sensing surface in the body, is typically located within the lens. The expressed aperture size is expressed in F/number.

The F-number is a relative value (reciprocal of relative aperture) obtained by the focal length of the lens/the lens light-passing diameter. The smaller the F value of the aperture, the more the amount of light entering the same unit time. The larger the F value of the aperture is, the smaller the depth of field is, and the background content of the shot will be blurred, similar to the effect of a telephoto lens.

The relative aperture, equal to the focal length of the lens divided by the entrance pupil diameter.

Positive refractive power, which may also be referred to as positive refractive power, indicates that the lens has a positive focal length and has the effect of converging light.

Negative refractive power, which may also be referred to as negative refractive power, indicates that the lens has a negative focal length and has a divergent light effect.

Total Track Length (TTL), which refers to the total length from the lens barrel head to the imaging surface, is a major factor in forming the height of the camera.

The focal ratio F #, the focal length divided by the aperture size, and the value of the focal length divided by the aperture size can be used to determine the light input amount of the optical system.

The abbe number, i.e. the dispersion coefficient, is the ratio of the refractive index differences of the optical material at different wavelengths, and represents the dispersion degree of the material.

A field of view (FOV) is an angle of view formed by two edges of an optical instrument, at which an object image of a measurement target can pass through the maximum range of a lens, with the lens of the optical instrument as a vertex. The size of the field angle determines the field of view of the optical instrument, with a larger field angle providing a larger field of view and a smaller optical magnification.

The optical axis is a ray that passes perpendicularly through the center of an ideal lens. When light rays parallel to the optical axis enter the convex lens, the ideal convex lens is that all the light rays converge at a point behind the lens, and the point where all the light rays converge is the focal point.

The object space is defined by the lens, and the space where the object is located is the object space.

The image space is defined by the lens, and the space where the light emitted by the object passes through the lens to form an image behind the lens is the image space.

The surface of the lens close to the object side can be called an object side surface; the side of the lens on which the image of the object is located is the image side, and the surface of the lens close to the image side can be referred to as the image side surface.

Stop, refers to the edge, frame or specially provided perforated barrier of the optical elements in the optical train assembly used to limit the size of the imaging beam or the unit of imaging space.

The aperture diaphragm is a diaphragm which limits the maximum inclination angle of the marginal ray in the on-axis point imaging light beam, namely, the diaphragm with the minimum incident aperture angle.

The entrance pupil is the common entrance for the beams from all points on the object plane.

The exit pupil is a common exit of the light beams emitted from each point on the object plane from the last pupil after passing through the whole optical system.

Axial chromatic aberration, also known as longitudinal chromatic aberration or positional chromatic aberration or axial chromatic aberration, is a bundle of light rays parallel to the optical axis, which converge at different positions in front and behind after passing through the lens. The reason is that the positions of the lens for imaging the light with various wavelengths are different, so that the focal planes of the images of the light with different colors cannot be overlapped during final imaging, and the polychromatic light is scattered to form dispersion.

Lateral chromatic aberration, also known as chromatic aberration of magnification, and the difference in magnification of the optical system for different colored light is known as chromatic aberration of magnification. The wavelength causes a change in the magnification of the optical system, with a consequent change in the size of the image.

Distortion (distortion), also known as distortion, is the degree to which an image made by an optical system on an object is distorted relative to the object itself. The distortion is caused by the influence of the spherical aberration of the diaphragm, the height of the intersection point of the principal rays of different view fields and the Gaussian image surface after passing through the optical system is not equal to the ideal image height, and the difference between the principal rays and the Gaussian image surface is the distortion. Therefore, the distortion only changes the imaging position of the off-axis object point on the ideal plane, so that the shape of the image is distorted, but the definition of the image is not influenced.

Optical distortion (optical distortion) refers to the degree of deformation that is calculated optically.

Diffraction limit (diffraction limit) means that an ideal object point is imaged by an optical system, and due to the diffraction limit, it is impossible to obtain the ideal image point, but a fraunhofer diffraction image is obtained. Since the aperture of a general optical system is circular, the images of Freund and Fischer diffraction are called Airy spots. Therefore, each object point is like a diffuse spot, two diffuse spots are not well distinguished after being close to each other, the resolution ratio of the system is limited, and the larger the spot is, the lower the resolution ratio is.

As shown in fig. 1, the left image is the front of the mobile phone, and the camera module 110 is installed on the left image, so that the mobile phone can be used for self-shooting and can also be used for shooting other objects by a photographer. The right picture in fig. 1 is the back of the mobile phone, and the camera module 120 is installed at the upper left part of the mobile phone, and can be used for shooting surrounding scenes and also can be used for self-shooting.

It should also be understood that the number of the

camera modules

110 and 120 is not limited to one, and may be two or more, for example, the terminal 100 may mount two camera modules 120 on the back side. The installation number of the camera modules is not limited.

110 and 120 may also be used for self-photographing, and the camera module 120 shown in the figure and located on the back of the mobile phone may also be used for a front camera, and the like, which is not limited in this embodiment.

It should be understood that other components, such as a handset, a key, a sensor, etc., may also be disposed on the terminal 100 shown in fig. 1, and the embodiment of the present application only exemplifies a terminal mounted with a camera module, but the components mounted on the terminal 100 are not limited thereto.

Fig. 2 shows an exploded view of the camera module 200, and the camera module 200 may be the camera module 110 or the camera module 120 shown in fig. 1, and the structure of the camera module is described below with reference to fig. 2.

The camera module 200 may include an optical lens (lens)210, an image sensor (sensor)220, an analog-to-digital converter (a/D converter) 230, an image processor 240, a memory 250, and the like.

Taking the terminal 100 as a mobile phone as an example, the operation principle of the camera module 200 may be that a light L reflected by a scene generates an optical image through an optical lens (lens)210 and projects the optical image onto the surface of the image sensor 220, the optical image is then converted into an electrical signal, i.e., an analog image signal S1, the analog image signal S1 is converted into a digital image signal S2 through an analog-to-digital converter a/D230, the digital image signal S2 is processed by an image processor 240, e.g., a Digital Signal Processing (DSP), to form a compressed image signal S3, which may be stored in a memory 250 for processing, and finally, an image may be viewed through a display or a display screen.

The optical lens 210 affects the imaging quality and the imaging effect, and mainly uses the refraction principle of a lens to perform imaging, i.e., the light of a scene passes through the lens to form a clear image on a focusing plane, and the image of the scene is recorded by a photosensitive material or a photoreceptor. The lens may be an integral body formed by combining different lenses (lenses) through a system, and the lens may be a lens structure, for example, the lens structure may be formed by several lenses, and the lens may be a plastic (plastic) lens, a glass (glass) lens, a spherical lens or an aspheric lens. The lens can be a fixed focal length lens or a zoom lens, and can also be a standard lens, a short-focus lens or a long-focus lens.

The image sensor 220 is a semiconductor chip, which includes hundreds of thousands to millions of photodiodes on the surface, and generates charges when being irradiated by light, and the charges are converted into digital signals by an analog-to-digital converter chip. The image sensor 220 may be a Charge Coupled Device (CCD) or a complementary metal-oxide semiconductor (CMOS). The CCD image sensor is made of a semiconductor material having high sensitivity, and converts light into electric charges, which are converted into digital signals by an analog-to-digital converter chip. A CCD consists of many photosites, usually in mega pixels. When the CCD surface is irradiated by light, each photosensitive unit reflects charges on the component, and signals generated by all the photosensitive units are added together to form a complete picture. The CMOS is mainly made of two elements of silicon and germanium, so that N (charged-charged) and P (charged-charged) semiconductors coexist on the CMOS, and the current generated by the two complementary effects can be recorded and interpreted as an image by a processing chip.

The function of the image processor 240 is to optimize the digital image signal through a series of complex mathematical algorithm operations, and finally transmit the processed signal to the display. The image processor 240 may be an image processing chip or a digital signal processing chip (DSP), and functions to transmit data obtained by the light sensing chip to the central processor in time and quickly and refresh the light sensing chip, so that the quality of the DSP chip directly affects the picture quality (such as color saturation, sharpness, etc.).

The camera module 200 may further include a holder, an auto focus driving assembly, an infrared filter, a circuit board, a connector, and peripheral electronic components (not shown). The fixer can be used for fixing the lens, and in addition, the fixer can also be provided with an infrared filter which can eliminate unnecessary light projected onto the image sensor 220 and prevent the image sensor 220 from generating false color or ripple so as to improve the effective resolution and the color reducibility of the image sensor 220. The auto-focus driving assembly may include a voice coil motor, a driving integrated circuit, etc. for auto-focusing or optically anti-shake of the lens. The circuit board may be a Flexible Printed Circuit (FPC) or a Printed Circuit Board (PCB) for transmitting an electrical signal, wherein the FPC may be a single-sided flexible board, a double-sided flexible board, a multi-layer flexible board, a rigid flexible board, a hybrid-structured flexible circuit board, or the like. Other components included in the camera module 200 are not described in detail herein.

It should be understood that the "lens" described in the embodiments of the present application may be understood as an integral lens, and may include one or more lenses, and the "lens" or "optic" may be understood as a lens in a lens structure or a lens or optic used to constitute the lens.

As mentioned above, in the optical system, the lens affects the imaging quality, and a key index of the lens is the F-stop value, which directly affects the core functions of the camera, such as night scene, capture, background blurring, video, etc. The large aperture/super large aperture can be the main trend of the mobile phone camera because the virtual background of the picture can be increased and the main body can be highlighted when the large aperture (the aperture F value is smaller) lens is used for shooting, the shutter speed and the focusing speed can be improved, and the imaging quality is better. The existing lens imaging structure is mostly formed by 5-piece or 6-piece plastic lenses, and the minimum aperture F value is 1.5. In addition, as the whole mobile phone is developed to be light and thin, the demand for miniaturization of the camera is gradually increased, and good imaging quality is also required. To obtain better imaging quality, the size and pixels of the photosensitive element can be increased, but the height of the camera module is also increased.

Therefore, it is necessary to design an imaging optical lens that can satisfy the requirements of a large aperture and a small total optical length while ensuring high imaging performance.

It should be noted that the large aperture in the embodiment of the present application may be understood as an aperture with an F value smaller than 2, and the extra-large aperture may be understood as an aperture with an F value smaller than 1.5.

As shown in fig. 3, an imaging optical lens 300 according to an embodiment of the present application includes 7 lenses. For convenience of description, the left side of the image capturing optical lens 300 is defined as the object side (hereinafter also referred to as the object side), the surface of the lens facing the object side can be referred to as the object side surface, the surface of the lens facing the object side can be referred to as the surface of the lens close to the object side, the right side of the image capturing optical lens 300 is defined as the image side (hereinafter also referred to as the image side), the surface of the lens facing the image side can be referred to as the image side surface, and the image side surface can be referred to as the surface of the lens close to the image side. The imaging optical lens 300 according to the embodiment of the present application includes, in order from an object side to an image side: a first lens 11, a second lens 12, a third lens 13, a fourth lens 14, a fifth lens 15, a sixth lens 16, and a seventh lens 17.

Optionally, a filter 19, such as a flat infrared cut filter, may also be disposed between the seventh lens 17 and the image sensor 20.

In an imaging system composed of multiple lenses, different combinations of lenses (e.g., order of lenses arranged along an optical path, lens material, refractive index, shape curvature, etc.) bring different optical properties and control light entering the optical system. In the embodiment of the present application, the image capturing optical lens 300 includes 7 lenses, wherein the first lens 11 mainly functions as a positive lens for condensing light, the second lens 12 mainly functions as a negative lens for diverging light, and the third lens 13 mainly functions as a positive lens for condensing light again, so that the first lens 11, the second lens 12, and the third lens 13 can reduce chromatic aberration of the system by combining different dispersion coefficients. In addition, the fourth lens 14 and the fifth lens 15 can spread light rays to a larger range, and the sixth lens 16 and the seventh lens 17 can correct curvature of field, distortion, high-order aberration and the like of the system. The image pickup optical lens 300 is described in detail below.

It should be noted that, for convenience of understanding and description, the embodiment of the present application defines the representation form of the relevant parameters of the image pickup optical lens, for example, f represents the focal length of the image pickup optical lens, f1 represents the focal length of the first lens, and the like, and the letter representations defined similarly are only schematic, but may also be represented in other forms, and the present application is not limited in any way.

It should also be noted that the units of the parameters related to the ratio in the following relations are kept consistent, for example, the units of numerator are millimeters (mm), and the units of denominator are also millimeters.

The imaging optical lens 300 of the present embodiment includes, in order from an object side to an image side:

a first lens 11, a second lens 12, a third lens 13, a fourth lens 14, a fifth lens 15, a sixth lens 16, and a seventh lens 17.

Each lens of the image pickup optical lens 300 satisfies the following relational expression:

0.5≤f/TTL≤1；

1.4≤n1≤2；

0≤v1-v2≤70；

15≤v3-v2≤50；

15≤v3-v4≤50；

It should be understood that the above-described "respective lenses of the image pickup optical lens 300" refers to the first lens 11, the second lens 12, the third lens 13, the fourth lens 14, the fifth lens 15, the sixth lens 16, and the seventh lens 17, and may also be denoted as the first lens 11 to the seventh lens 17.

The above relation specifies that the ratio range of the focal length to the total optical length of the image pickup optical lens 300 is 0.5-1/TTL, which is favorable for scaling under the same optical system architecture.

It should be understood that the focal length of the image pickup optical lens 300 can be understood as a focal length when the lens included in the image pickup optical lens 300 is regarded as one optical lens.

The above-mentioned relational expression specifies that the refractive index of the first lens 11 is 1.4. ltoreq. n 1. ltoreq.2, and the selection range of the refractive index of the first lens 11 is wider, so that a thin lens having strong aberration correction ability can be easily obtained. For example, the first lens 11 may be a glass lens, which has a larger refractive index selectable range relative to the refractive index range (1.55-1.65) of an optical plastic lens, and thus, a thinner glass lens with better performance can be obtained, and the optical total length can be reduced.

The above relation specifies that the range of the difference between the abbe numbers of the first lens 11 and the second lens 12 is 0-v 1-v 2-70, the range of the difference between the abbe numbers of the second lens 12 and the third lens 13 is 15-v 3-v 2-50, and the range of the difference between the abbe numbers of the third lens 13 and the fourth lens 14 is 15-v 3-v 4-50, which is beneficial to reducing the system dispersion.

From the above ranges, it can be known that v1> v2, v2< v3, v3> v4, the combination of such lenses is advantageous for realizing a large aperture (equivalent to a reduction in F value of the aperture) and eliminating chromatic aberration. When the focal length, the total optical length, the refractive index of the constituent lenses, and the abbe number of the imaging optical lens 300 according to the embodiment of the present application satisfy the above relationship, the imaging optical lens 300 can satisfy the requirements of a large aperture or an ultra-large aperture and a small total optical length while obtaining high imaging performance.

Alternatively, each lens of the image pickup optical lens 300 may also satisfy the following relationship:

-50. ltoreq. v5-v 6. ltoreq.50, and/or-50. ltoreq. v6-v 7. ltoreq.50;

wherein v5 is the abbe number of the fifth lens, v6 is the abbe number of the sixth lens, and v7 is the abbe number of the seventh lens.

The above relational expression defines a range of the difference in abbe numbers between the sixth lens 16 and the seventh lens 17, and is advantageous for reducing the system dispersion.

In the embodiment of the present application, the abbe number of the sixth lens 16 and the abbe number of the seventh lens 17 may be the same or close to each other (i.e., the difference is smaller than a certain range), for example, similar materials or the same materials are used for the sixth lens 16 and the seventh lens 17, in other words, materials with refractive indexes close to or the same as each other are used for the sixth lens and the seventh lens, which can meet the performance requirements for large aperture and small total optical length of the image pickup optical lens.

Of course, the abbe number of the sixth lens element 16 and the abbe number of the seventh lens element 17 may also differ by a larger value, for example, compared to the sixth lens element 16, the seventh lens element 17 is made of a material with a higher abbe number or a higher refractive index, which is beneficial to reducing the total optical length of the photographing optical lens, and is equivalent to reducing the height of the photographing optical lens or the camera module, thereby reducing the size of the photographing optical lens or the camera module, and also meeting the performance requirements for a large aperture and a small total optical length of the photographing optical lens, and being beneficial to realizing the lightness and thinness. Similarly, the sixth lens 16 may be made of a material having a high ready number or a high refractive index as compared with the seventh lens 17.

Similarly, the fifth lens, the sixth lens and the seventh lens in the embodiments of the present application may be combined in any combination of refractive index materials, for example, the fifth lens, the sixth lens and the seventh lens may be made of materials with the same or close refractive index; any two of the materials with the same or close refractive indexes can be adopted, and the other material with a larger refractive index difference is adopted; three materials with different refractive indexes can be selected.
