M360372 V. New description: [New technical field] This is a four-piece small photographic lens, camera module and photographic device, especially one suitable for CCD (Charge Coupled 5 Device) or CMOS (Complementary Metal). a four-piece small-sized photographic lens that images an optical image of a subject on a photographic element, and a camera module that converts an optical image formed by the four-piece small photographic lens into a photographic signal, and loads the four-piece structure A small-sized photographic lens is used for photographing digital cameras or mobile phones with photographic lenses 10 and personal digital assistants (PDA: Personal Digital Assistance). [Prior Art] In recent years, with the spread of personal computers in general households, digital cameras that input image information such as landscapes or portraits into a personal computer are rapidly becoming popular. Moreover, the phenomenon of loading a camera module for image input on a mobile phone is also increasing. A photographic element such as ccd or CMOS is used on a device having such a photographing function. Further, in recent years, the miniaturization of these photographic elements has been increased, and the photographic apparatus as a whole and the photographic lens mounted thereon have been required to be miniaturized. At the same time, the high pixelation of the photographic elements is also increasing, and high resolution and high performance of the photographic lens are required. For this requirement, for example, in order to achieve miniaturization (shortening of the optical axis direction, low-cost, high-resolution, and the number of lenses is set to four-piece structure, in order to achieve south performance, an aspherical solution is actively used. Patent No. 4, M360372, Clauses 1 to 4, disclose such a four-piece structure and use an aspherical photographic lens. [Patent 1] Japanese Patent Publication No. 2_3_3〇2〇57 [Prediction 2 Japanese Patent Publication No. 2007-17984 [Patent Document 3] Japanese Patent Publication No. 2002-228922 (Patent No. 4) U.S. Patent No. 6,9i 7,479, in the above-mentioned photographic apparatus, requires mass production Limits the defect of optical performance® to a minimum while reducing the length (=height) of the optical axis direction of the camera module as a whole. However, if the lens back focal length (from the most image side of the lens to the image plane) When the distance is simply too small, it is generally difficult to meet the specifications of the light emission angle or the appearance of scratches on the final lens surface, foreign matter, etc. Moreover, if the thickness of the lens system is full thickness = the most When the distance between the vertex of the lens surface on the body side and the vertex of the most image side lens surface 15 is simply too small, it is necessary to make the center thickness 1) of each lens element too small or to make the effect of the aspheric surface too strong. A defect occurs in which the lens shape is internally warped, the shaft is tilted, and the manufacturability required by the appearance specifications occurs. Therefore, when the total length is shortened, the lens back focal length, the thickness DL of the lens system, the center thickness of each lens element, and the like are set to be small, and these are assembled in a balanced manner under appropriate conditions, in mass production. Maintain good optical performance. Since the light barrier is emitted in the second light transmission, the photographic lens described in the above Patent Document 1, the rear side of the mirror, has a problem that the angle of the entire length is shortened. Further, in the pre-patent 2, various types of four-piece photographic lenses are disclosed, but it is difficult to say that each embodiment is a very suitable design of 5 25 M360372. For example, the ratio of the embodiment of the type with a small focal length (representing the value before and after 4) to the total length of the focal length is greater than 1.25. The lenses of the other embodiments are large, and it is considered that the manufacturability of the center thickness and the like of the miniaturization is not sufficiently considered. In addition, in the photographic 5 lens shown in the patents 3 and 4, since the focal length, the total length, and the lens thickness of the embodiment are large, it is considered that the miniaturization of the photographic element has not been sufficiently considered in recent years. Manufacturability of the center thickness and the like.

An optical cover CG for protecting the photographic surface, an infrared cut-off filter or a low-pass filter or the like may be disposed between the fourth lens L4 and the imaging surface (photographing surface) Simg. This photographic lens also has a diaphragm St. The diaphragm St is an optical aperture light, and is preferably disposed on the so-called "front side diaphragm" on the object side. Here, the "most object side" means that the optical axis is on the object side (see FIG. 1) at the outer edge position E of the surface on the object side of the first lens, and is also included in the optical axis, for example. Up, g has been placed between the position of the top of the object side M360372 in the first lens [1] and the outer edge position E of the surface on the object side in the first lens L1. However, it is also possible to arrange the light barrier to be placed on the image side of the first lens and the moonlight column. For example, the embodiments of Figs. 12 to 14 (Figs. 12 to 5 and Fig. 14) may be disposed between the first lens L1 and the second lens L2. The term "between the first lens L1 and the second lens L2" as used herein means the outer edge position of the surface of the object side of the lens L1 or the outer edge position of the image side surface and the second on the optical axis. The outer edge position of the surface of the lens L2 on the object side. Of course, it is also included in the case where the optical barrier is disposed on the optical axis, and the light barrier St is disposed in the vicinity of the surface vertex position 10 on the image side of the first lens L丨, and the light is disposed in the vicinity of the surface vertex position on the object side of the second lens L2. Block St. Both surfaces of the photographic lens 'fourth lens L4' are set to have an aspherical shape. For the first lens L1, the second lens L2, and the third lens L3, it is preferable that at least one of the breads contains an aspherical surface. 15 The first lens 匕1 has a positive power. In the first lens L1, the surface on the object side is a convex surface in the vicinity of the optical axis. Preferably, the first lens L1 has a convex shape in the vicinity of the optical axis and a convex shape in the vicinity of the optical axis. However, in the eleventh to thirteenth embodiments (FIG. 11 to FIG. 13), the surface on the image side may be a concave shape in the vicinity of the optical axis, and the positive meniscus 20 shape in which the convex surface faces the object side in the vicinity of the optical axis. lens.

However, as in the twelfth embodiment (Fig. 12), it may have two concave shapes. In the i-th embodiment (Fig. 3), the third lens L3 is formed in the vicinity of the optical axis, and the surface on the object side is a convex surface, and the surface on the image side is a concave moon shape. In the second to the uth and thirteenth to thirteenth embodiments (FIG. 2 to FIG. 9 and FIG. 13 to FIG. 15), the third lens L3 is close to the optical axis, and the surface on the object side is concave. At the same time, the side of the image side is a convex meniscus shape. The surface of the fourth lens L4 on the image side has a concave shape of 10 in the vicinity of the optical axis toward the image side, and an aspherical surface which is convex toward the image side in the peripheral portion. For example, the fourth lens L4' is preferably formed such that the surface on the object side is convex in the vicinity of the optical axis, and the surface on the image side is in the shape of a concave moon. In the first embodiment of the figure, the fourth lens L4 is set to have two concave shapes, but in other embodiments, it is set to a meniscus 15 20. The fourth lens L4' is preferably in accordance with the structure of other lens elements, in the light. ^近适#Select positive or negative m, for example, 'When the photographic lens is used, and the * column position is the middle light barrier', if the paraxial power of the fourth lens L4 is set to: ', it is advantageous for the shortening of the full length. . In addition, when the near-optical power of the fourth lens L4 is set to positive ', the shape of the first lens U is set to the f-moon shape, and the total length is shortened, and the spherical aberration or the field curvature is corrected. This photographic lens satisfies the following conditional expressions (1) to (3): ... 40 (1); 12~ f/fl - 2·3 ......

In addition, the number of lenses is the maximum length of the object when the distance is infinite. Moreover, it is preferable to appropriately and selectively satisfy the following conditional expression: ^ ^ 60 (4); where, ^1: Abbe number of the first lens L1. Moreover, it is preferable to appropriately and selectively satisfy the following conditional expression: 1.0^ |R7/R8|^ 1.2 ......(5); 15 20 〇.l^D5/f^〇.15 ......(6 Where R7 is the paraxial radius of curvature of the object-side surface of the fourth lens L4, R8. The paraxial curvature of the image side surface of the fourth lens L4 is half a circle, f: the overall focal length, D5: The center thickness of the three lens L3. The figure is an embodiment showing a camera module in which the imaging lens of the present embodiment is assembled. Further, Fig. 32 (A) and Fig. 32 (B) show a mobile phone with a photographic lens as an example of an imaging device in which the camera module of Fig. 31 is mounted. 13 M360372 In the cellular phone with a photographic lens shown in Figs. 32(A) and (B), both the upper casing 2A and the lower casing 2B' are rotatably formed in the direction of the arrow in Fig. 32(A). An operation key 21 or the like is provided in the lower casing 2B. The upper housing 2 is provided with a camera unit 1 (Fig. 32 (B)) and a display unit 22 (Fig. 32 (A)). The display unit 22 is constituted by a display panel such as a 5 [CD (Liquid Crystal Panel) or EL (Electro-Luminescence) panel. The display unit 22 is disposed on the side that becomes the inner surface at the time of folding. The display unit 22' can display an image or the like photographed by the camera unit 1 in addition to various menus relating to the telephone function. The camera unit 1 is disposed, for example, on the inner surface side of the upper housing 2A. However, the position where the camera unit is set is not limited to 10. The camera unit 1 has the camera module of the present embodiment. As shown in FIG. 31, the camera module includes a lens barrel 3 that houses the photographic lens 2, a support substrate 4 that supports the lens barrel, and a position on the support substrate 4 that is provided on the imaging surface of the corresponding photographic lens 2A. The photographic element (not shown) further includes a flexible substrate 5 electrically connected to the photographic element on the support substrate 4 and electrically connected to the flexible substrate 5, and is connectable to the photographic lens The external connection terminal 6 of the structure of the signal processing circuit on the main body side of the mobile device, etc. The structural elements are integrally formed. In the camera module shown in Fig. 31, the optical 2 formed by the photographic lens 2 〇 The imaging image is converted into an electrical imaging signal by the imaging element, and the imaging signal is output to the signal processing circuit on the side of the imaging device main body via the flexible substrate 5 and the external connection terminal 6. Here, in the camera module, the imaging is performed. Since the lens of the present embodiment is used for the lens, it is possible to obtain a high-resolution imaging signal that sufficiently corrects the aberration 14 M360372. On the side of the imaging device main body, two resolutions can be generated based on the k-number of the imaging device. In addition, the imaging device of the present embodiment is not limited to a mobile phone with a photographic lens, for example, a digital camera or a PDA. 5 Next, the action and effect of the photographic lens having the above configuration, particularly regarding the conditional expression, will be described in more detail. In the photographic lens of the present embodiment, in the lens structure of the entire four lenses, the aspherical surface is efficiently used to optimize the shape of each lens, and the lens structure is realized by satisfying a predetermined conditional expression. Optimized, therefore, 10 is fully considered for manufacturability so that the cost is not increased, and high imaging performance can be obtained while shortening the total length. 15 20 Regarding the aspherical shape 'especially the fourth lens L4 is at the center portion and The peripheral portion is changed into a different shape ′, and the curvature of field is favorably corrected from the central portion of the image plane to the peripheral portion. In the fourth lens, compared with the first lens u, the second lens L2, and the third lens L3 'The light beam is separated at every viewing angle. Therefore, the image side surface of the fourth lens 最近 closest to the final lens surface of the photographic element is concave toward the image side near the optical axis. On the other hand, the peripheral portion has a convex shape toward the image side. The aberration of each viewing angle can be appropriately corrected, and the incident angle of the light beam to the imaging element is controlled to be equal to or lower than the fixed angle. Thus, the distribution of light in the entire area of the imaging surface can be reduced (4). Conducive to correction of curvature of field or distortion, etc. Incident of the main surface of the element 'light stop St Generally, in the photographic lens system, the telecentricity, that is, the incident angle to the photographic light is preferably close to the parallel axis (in the The photographing angle is close to zero to the normal of the photographic surface. To ensure that the telecentricity 15 M360372 is preferably placed on the object side as much as possible. On the other hand, if the light stop St is disposed on the lens side from the object side of the first lens L1 Further, the portion (the distance between the diaphragm St and the lens surface on the most object side) at the position away from the object side direction is added as the optical path length 'so that' is disadvantageous in miniaturization of the overall structure. 5, by 'arranging the diaphragm St on the optical axis Z1 at the same position as the vertex position of the object-side lens surface of the first lens L1' or on the object-side surface vertex position and image side of the first lens l1 Between the vertex positions of the faces, the full length can be shortened and the telecentricity can be ensured. When the telecentricity is further emphasized, the diaphragm St is placed on the optical axis on the top 10 point of the object side of the first lens and the outer edge position E of the object side surface of the first lens L1 (see the figure). The following is a description of the specific meaning of each conditional expression. The conditional expression (1) relates to the material of the third lens L3, and defines a value of an appropriate Abbe number. By satisfying the conditional expression (1) 'easy and good Keep the axis chromatic aberration and

Magnification chromatic aberration. When the upper limit of the conditional expression (1) is exceeded, the short-wavelength side of the chromatic aberration on the periphery is excessively negative, and the resolution of the periphery around the chromatic aberration of magnification is deteriorated. The conditional expression (2) relates to the focal length fl of the first lens u. By satisfying the conditional expression (7)', the relationship between the full length and the spherical aberration can be favorably maintained. When the lower limit of conditional expression (7) is exceeded 20, the refractive power of the first lens ^ becomes too strong, and the f-plane aberration tends to be too negative. In addition, the angle at which the light is emitted tends to become large. If the super is still beyond the upper limit, there is a tendency that the overall length becomes longer. Conditional expression (7) relates to the full length TL of the lens. By satisfying the conditional expression (3), it is possible to maintain the shortening of the entire length while maintaining high imaging performance. 16 M360372 Conditional expression (4) relates to the material of the first lens 11 and specifies the value of the appropriate Abbe number. When the lower limit of the conditional expression (4) is exceeded, the chromatic aberration on the shaft becomes large, which is not preferable. In order to obtain better performance, the value range of the conditional expression (4) is preferably 5: ^ (4,); further preferably: ^1^80 ...... (4) , , ); * The condition (5) relates to the paraxial shape of the fourth lens L4. The image plane curvature can be favorably maintained by satisfying the condition 1 ( (5)'. When the lower limit of the conditional expression (5) is exceeded, the tangential image plane becomes a negative measurement, and the distortion aberration tends to be a pillow type. If the upper limit is exceeded, the sagittal image surface is too negative for the tangential image plane. The conditional expression (6) relates to the center thickness D5 of the third lens L3. In particular, under the conditions of the above conditional expressions (1), (4), and (5), if the upper limit of the conditional expression (6) is exceeded, 15 is bent into a barrel shape, and the image plane curvature becomes a positive side. In addition, the short-wavelength side of the chromatic aberration of the double f becomes the negative side, and it is difficult to maintain the aberration balance high in the periphery. When the lower limit is exceeded, the thickness of the third lens L3 is thinned as a whole, and is easily restricted by processing or molding. As described above, according to the photographic lens of the present embodiment, the total imaging performance* can be maintained while shortening the total length by 20 times. Further, according to the camera module of the present embodiment, the imaging signal of the optical image formed by the photographic lens having the high imaging performance while shortening the total length is performed, so that the entire module can be miniaturized. At the same time, a high-resolution photographic signal can be obtained. Further, according to the image pickup apparatus of the present embodiment, since the camera M360372 module is mounted, it is possible to achieve a high-resolution photographing signal while achieving a miniaturization of the photographing portion, and a high-resolution photograph can be obtained based on the photographing signal. image.
