       [0001]    1. Technical Field

         [0004]    In recent years, with the rise of portable electronic devices having camera functionalities, the demand for an optical image capturing system is raised gradually. The image sensing device of ordinary photographing camera is commonly selected from charge coupled device (CCD) or complementary metal-oxide semiconductor sensor (CMOS Sensor). In addition, as advanced semiconductor manufacturing technology enables the minimization of pixel size of the image sensing device, the development of the optical image capturing system towards the field of high pixels. Therefore, the requirement for high imaging quality is rapidly raised. 
         [0005]    The conventional optical system of the portable electronic device usually has a two or three-piece lens. However, the optical system is asked to take pictures in a dark environment, in other words, the optical system is asked to have a large aperture. An optical system with large aperture usually has several problems, such as large aberration, poor image quality at periphery of the image, and hard to manufacture. In addition, an optical system of wide-angle usually has large distortion. Therefore, the conventional optical system provides high optical performance as required. 
         [0006]    It is an important issue to increase the quantity of light entering the lens and the angle of field of the lens. In addition, the modern lens is also asked to have several characters, including high pixels, high image quality, small in size, and high optical performance.

         [0141]    The detail parameters of the first preferred embodiment are listed in Table 1, in which the unit of radius of curvature, thickness, and focal length are millimeter, and surface 0-14 indicates the surfaces of all elements in the system in sequence from the object side to the image side. Table 2 is the list of coefficients of the aspheric surfaces, in which A1-A20 indicate the coefficients of aspheric surfaces from the first order to the twentieth order of each aspheric surface. The following embodiments have the similar diagrams and tables, which are the same as those of the first embodiment, so we do not describe it again. 
       Second Embodiment 
       [0142]    As shown in  FIG. 2A  and  FIG. 2B , an optical image capturing system of the second preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  200 , a first lens  210 , a second lens  220 , a third lens  230 , a fourth lens  240 , an infrared rays filter  270 , an image plane  280 , and an image sensor  290 . 
         [0143]    The first lens  210  has positive refractive power, and is made of plastic. An object-side surface thereof, which faces the object side, is a convex aspheric surface, and an image-side surface thereof, which faces the image side, is a convex aspheric surface. 
         [0144]    The second lens  220  has negative refractive power, and is made of plastic. An object-side surface  222  thereof, which faces the object side, is a concave aspheric surface, and an image-side surface  224  thereof, which faces the image side, is a concave aspheric surface. The object-side surface  222  has an inflection point, while the image-side surface  224  has two inflection points. 
         [0145]    The third lens  230  has positive refractive power, and is made of plastic. An object-side surface  232 , which faces the object side, is a concave aspheric surface, and an image-side surface  234 , which faces the image side, is a convex aspheric surface. The object-side surface  232  has two inflection points, while the image-side surface  234  has an inflection point. 
         [0146]    The fourth lens  240  has negative refractive power, and is made of plastic. An object-side surface  242  thereof, which faces the object side, is a convex surface, and an image-side surface  244  thereof, which faces the image side, is a concave aspheric surfaces. The object-side surface  242  has two inflection points, while the image-side surface  244  has an inflection point. 
         [0147]    The infrared rays filter  270  is made of glass, and between the fourth lens  240  and the image plane  280 . The infrared rays filter  270  gives no contribution to the focal length of the system. 
         [0148]    The optical image capturing system of the second preferred embodiment has the following parameters, which are |f2|+|f3|=2.8463 mm; |f1|+|f4|=2.1524 mm; and |f2|+|f3|&gt;|f1|+|f4|, where f1 is a focal length of the first lens  210 ; f2 is a focal length of the second lens  220 ; f3 is a focal length of the third lens  230 ; and f4 is a focal length of the fourth lens  240 . 
         [0149]    The optical image capturing system of the second preferred embodiment further satisfies TP 3 =0.3419 mm and TP 4 =0.1800 mm, where TP 3  is a thickness of the third lens  230  on the optical axis, and TP 4  is a thickness of the fourth lens  240  on the optical axis. 
         [0150]    In the second embodiment, the first and the third lenses  210 ,  230  are positive lenses, and their focal lengths are f1 and f3 respectively. The optical image capturing system of the second preferred embodiment further satisfies ΣPP=f1+f3=2.0394 mm and f1/(f1+f3)=0.6445, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  210  to the other positive lens to avoid the significant aberration caused by the incident rays. 
         [0151]    The optical image capturing system of the second preferred embodiment further satisfies ΣNP=f2+f4=−2.9592 mm and f4/(f2+f4)=0.7168, where f2 and f4 are focal lengths of the second and the fourth lenses  220 ,  240 , and ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the fourth lens  240  to the other negative lens to avoid the significant aberration caused by the incident rays. 
         [0152]    The optical image capturing system of the first preferred embodiment further satisfies HVT 31 =0.2938 mm and HVT 32 =0.4785 mm, where HVT 31  is a distance perpendicular to the optical axis between a critical point C 31  on the object-side surface  132  of the third lens  130  and the optical axis; HVT 32  is a distance perpendicular to the optical axis between a critical point C 32  on the image-side surface  134  of the third lens  130  and the optical axis. 
         [0153]    The optical image capturing system of the first preferred embodiment further satisfies HVT 41 =0.2727 mm and HVT 42 =0.5598 mm, where HVT 41  is a distance perpendicular to the optical axis between a critical point C 41  on the object-side surface  142  of the fourth lens  140  and the optical axis; HVT 42  is a distance perpendicular to the optical axis between a critical point C 42  on the image-side surface  144  of the fourth lens  140  and the optical axis. 
         [0154]    The optical image capturing system of the first preferred embodiment further satisfies ΣPPR=f/f1+f/f3=2.81647; ΣNPR=f/f2+f/f4=2.19093; and ΣPPR/|ΣNPR|=1.28551, where ΣPPR is a sum of the positive refractive power of all the positive lenses, and ΣNPR is a sum of the negative refractive power of all the negative lenses. 
         [0155]    The parameters of the lenses of the second embodiment are listed in Table 3 and Table 4.

       Third Embodiment 
       [0158]    As shown in  FIG. 3A  and  FIG. 3B , an optical image capturing system of the third preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  300 , a first lens  310 , a second lens  320 , a third lens  330 , a fourth lens  340 , an infrared rays filter  370 , an image plane  380 , and an image sensor  390 . 
         [0159]    The first lens  310  has positive refractive power, and is made of plastic. An object-side surface  312  thereof, which faces the object side, is a convex aspheric surface, and an image-side surface  314  thereof, which faces the image side, is a concave aspheric surface, and the object-side surface  312  and the image-side surface  314  both have an inflection point respectively. 
         [0160]    The second lens  320  has positive refractive power, and is made of plastic. An object-side surface  322  thereof which faces the object side is a concave aspheric surface, and an image-side surface  324  thereof which faces the image side is a convex aspheric surface. 
         [0161]    The third lens  330  has negative refractive power, and is made of plastic. An object-side surface  332 , which faces the object side, is a concave aspheric surface, and an image-side surface  334 , which faces the image side, is a convex aspheric surface, and the image-side surface  334  has an inflection point. 
         [0162]    The fourth lens  340  has a positive refractive power, and is made of plastic. An object-side surface  342 , which faces the object side, is a convex aspheric surface, and an image-side surface  344 , which faces the image side, is a concave aspheric surface. The object-side surface  342  has two inflection points, while the image-side surface  344  has an inflection point. 
         [0163]    The infrared rays filter  370  is made of glass, and between the fourth lens  340  and the image plane  380 . The infrared rays filter  370  gives no contribution to the focal length of the system. 
         [0164]    The parameters of the lenses of the third preferred embodiment are |f2|+|f3|=3.2561 mm; |f1|+|f4|=4.3895 mm; and |f2|+|f3|&lt;|f1+|f4|, where f1 is a focal length of the first lens  310 ; f2 is a focal length of the second lens  320 ; f3 is a focal length of the third lens  330 ; and f4 is a focal length of the fourth lens  340 . 
         [0165]    The optical image capturing system of the third preferred embodiment further satisfies TP 3 =0.2115 mm and TP 4 =0.5131 mm, where TP 3  is a thickness of the third lens  330  on the optical axis, and TP 4  is a thickness of the fourth lens  340  on the optical axis. 
         [0166]    The optical image capturing system of the third preferred embodiment further satisfies ΣPP=f1+f2+f4=6.3099 mm and f1/(f1+f2+f4)=0.3720, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  310  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0167]    The optical image capturing system of the third preferred embodiment further satisfies ΣNP=f3=−1.3357 mm and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens.

       Fourth Embodiment 
       [0171]    As shown in  FIG. 4A  and  FIG. 4B , an optical image capturing system of the fourth preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  400 , a first lens  410 , a second lens  420 , a third lens  430 , a fourth lens  440 , an infrared rays filter  470 , an image plane  480 , and an image sensor  490 . 
         [0172]    The first lens  410  has positive refractive power, and is made of plastic. An object-side surface  412  thereof, which faces the object side, is a convex aspheric surface, and an image-side surface  414  thereof, which faces the image side, is a concave aspheric surface, and each of them has an inflection point respectively. 
         [0173]    The second lens  420  has positive refractive power, and is made of plastic. An object-side surface thereof, which faces the object side, is a concave aspheric surface, and an image-side surface thereof, which faces the image side, is a convex aspheric surface. 
         [0174]    The third lens  430  has negative refractive power, and is made of plastic. An object-side surface  432 , which faces the object side, is a concave aspheric surface, and an image-side surface  434 , which faces the image side, is a convex aspheric surface. The object-side surface  432  has two inflection points, while the image-side surface  434  has an inflection point. 
         [0175]    The fourth lens  440  has positive refractive power, and is made of plastic. An object-side surface  442 , which faces the object side, is a convex aspheric surface, and an image-side surface  444 , which faces the image side, is a concave aspheric surface. The object-side surface  442  and the image-side surface  444  both have an inflection point respectively. 
         [0176]    The infrared rays filter  470  is made of glass, and between the fourth lens  440  and the image plane  480 . The infrared rays filter  470  gives no contribution to the focal length of the system. 
         [0177]    The optical image capturing system of the fourth preferred embodiment has the following parameters, which are |f2|+|f3|=4.3448 mm; |f1|+|f4|=3.9627 mm; and |f2|+|f3|&gt;|f1|+|f4|, where f1 is a focal length of the first lens  410 ; f2 is a focal length of the second lens  420 ; f3 is a focal length of the third lens  430 ; and f4 is a focal length of the fourth lens  440 . 
         [0178]    The optical image capturing system of the fourth preferred embodiment further satisfies TP 3 =0.1900 mm and TP 4 =0.5171 mm, where TP 3  is a thickness of the third lens on the optical axis, and TP 4  is a thickness of the fourth lens on the optical axis. 
         [0179]    In the fourth embodiment, the optical image capturing system of the fourth preferred embodiment further satisfies ΣPP=f1+f2+f4=6.9824 mm and f1/(f1+f2+f4)=0.3392, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  410  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0180]    The optical image capturing system of the fourth preferred embodiment further satisfies ΣNP=f3=−1.3251 mm and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens. 
         [0181]    The parameters of the lenses of the fourth embodiment are listed in Table 7 and Table 8.

       [0184]    As shown in  FIG. 5A  and  FIG. 5B , an optical image capturing system of the fifth preferred 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  570 , an image plane  580 , and an image sensor  590 . 
         [0185]    The first lens  510  has positive refractive power, and is made of plastic. An object-side surface  512  thereof which faces the object side is a convex aspheric surface, and an image-side surface  514  thereof which faces the image side is a concave aspheric surface, wherein the object-side surface  512  and the image-side surface  514  both have an inflection point respectively. 
         [0186]    The second lens  520  has positive refractive power, and is made of plastic. An object-side surface  522  thereof, which faces the object side, is a concave aspheric surface, and an image-side surface  524  thereof, which faces the image side, is a convex aspheric surface. 
         [0187]    The third lens  530  has negative 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 image-side surface  534  has an inflection point. 
         [0188]    The fourth lens  540  has a positive refractive power, and is made of plastic. An object-side surface  542 , which faces the object side, is a convex aspheric surface, and an image-side surface  544 , which faces the image side, is a concave aspheric surface. The object-side surface  542  has two inflection points, while the image-side surface  544  has an inflection point. 
         [0189]    The infrared rays filter  570  is made of glass, and between the fourth lens  540  and the image plane  580 . The infrared rays filter  570  gives no contribution to the focal length of the system. 
         [0190]    The parameters of the lenses of the fifth preferred embodiment are |f2|+|f3|=7.6703 mm; |f1|+|f4|=7.7843 mm; and |f2|+|f3|&gt;|f1|+|f4|, where f1 is a focal length of the first lens  510 ; f2 is a focal length of the second lens  520 ; f3 is a focal length of the third lens  530 ; and f4 is a focal length of the fourth lens  540 . 
         [0191]    The optical image capturing system of the fifth preferred embodiment further satisfies TP 3 =0.3996 mm and TP 4 =0.9713 mm, where TP 3  is a thickness of the third lens  530  on the optical axis, and TP 4  is a thickness of the fourth lens  540  on the optical axis. 
         [0192]    The optical image capturing system of the fifth preferred embodiment further satisfies ΣPP=f1+f2+f4=13.1419 mm and f1/(f1+f2+f4)=0.2525, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  510  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0193]    The optical image capturing system of the fifth preferred embodiment further satisfies ΣNP=f3=−2.3127 mm; and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens. 
         [0194]    The parameters of the lenses of the fifth embodiment are listed in Table 9 and Table 10.

       Sixth Embodiment 
       [0197]    As shown in  FIG. 6A  and  FIG. 6B , an optical image capturing system of the sixth preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  600 , a first lens  610 , a second lens  620 , a third lens  630 , a fourth lens  640 , an infrared rays filter  670 , an image plane  680 , and an image sensor  690 . 
         [0198]    The first lens  610  has positive refractive power, and is made of plastic. An object-side surface  612  thereof which faces the object side is a convex aspheric surface, and an image-side surface  614  thereof which faces the image side is a concave aspheric surfaces. The object-side surface  612  and the image-side surface  614  both have an inflection point respectively. 
         [0199]    The second lens  620  has positive 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. 
         [0200]    The third lens  630  has negative refractive power, and is made of plastic. An object-side surface  632 , which faces the object side, is a concave aspheric surface, and an image-side surface  634 , which faces the image side, is a convex aspheric surface. The object-side surface  632  has two inflection points, while the image-side surface  634  has an inflection point. 
         [0201]    The fourth lens  640  has positive refractive power, and is made of plastic. An object-side surface  642 , which faces the object side, is a convex aspheric surface, and an image-side surface  644 , which faces the image side, is a concave aspheric surface, and the object-side surface  642  has two inflection points, while the image-side surface  644  has an inflection point. 
         [0202]    The infrared rays filter  670  is made of glass, and between the fourth lens  640  and the image plane  680 . The infrared rays filter  670  gives no contribution to the focal length of the system. 
         [0203]    The optical image capturing system of the sixth preferred embodiment has the following parameters, which are |f2|+|f3|=5.7804 mm; If |f1|+|f4|=8.0922 mm; and |f2|+|f3|&lt;|f1|+|f4|. 
         [0204]    The optical image capturing system of the sixth preferred embodiment further satisfies TP 3 =0.5226 mm and TP 4 =0.8727 mm, where TP 3  is a thickness of the third lens on the optical axis, and TP 4  is a thickness of the fourth lens on the optical axis. 
         [0205]    The optical image capturing system of the sixth preferred embodiment further satisfies ΣPP=f1±f2+f4=11.8154 mm and f1/(f1+f2+f4)=0.2908, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  610  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0206]    The optical image capturing system of the sixth preferred embodiment further satisfies ΣNP=f3=−2.0572 mm and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens. 
         [0207]    The parameters of the lenses of the sixth embodiment are listed in Table 11 and Table 12.

       Seventh Embodiment 
       [0211]    As shown in  FIG. 7A  and  FIG. 7B , an optical image capturing system of the seventh preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  700 , a first lens  710 , a second lens  720 , a third lens  770 , a fourth lens  740 , an infrared rays filter  770 , an image plane  780 , and an image sensor  790 . 
         [0212]    The first lens  710  has positive refractive power, and is made of plastic. An object-side surface  712  thereof, which faces the object side, is a convex aspheric surface, and an image-side surface  714  thereof, which faces the image side, is a convex aspheric surface, and the object-side surface  712  has an inflection point. 
         [0213]    The second lens  720  has positive refractive power, and is made of plastic. An object-side surface  722  thereof which faces the object side is a concave aspheric surface, and an image-side surface  724  thereof which faces the image side is a convex aspheric surface. 
         [0214]    The third lens  730  has negative refractive power, and is made of plastic. An object-side surface  732 , which faces the object side, is a concave aspheric surface, and an image-side surface  734 , which faces the image side, is a convex aspheric surface. The image-side surface  732  has two inflection points, while the image-side surface  734  has an inflection point. 
         [0215]    The fourth lens  740  has a positive refractive power, and is made of plastic. An object-side surface  742 , which faces the object side, is a convex aspheric surface, and an image-side surface  744 , which faces the image side, is a concave aspheric surface. The object-side surface  742  and the image-side surface  744  both have an inflection point respectively. 
         [0216]    The infrared rays filter  770  is made of glass, and between the fourth lens  740  and the image plane  780 . The infrared rays filter  770  gives no contribution to the focal length of the system. 
         [0217]    The parameters of the lenses of the third preferred embodiment are |f2|+|f3|=6.3879 mm; |f1|+|f4|=7.3017 mm; and |f2|+|f3|&lt;|f1|+|f4|, where f1 is a focal length of the first lens  710 ; f2 is a focal length of the second lens  720 ; f7 is a focal length of the third lens  730 ; and f4 is a focal length of the fourth lens  740 . 
         [0218]    The optical image capturing system of the third preferred embodiment further satisfies TP 3 =0.342 mm and TP 4 =0.876 mm, where TP 3  is a thickness of the third lens  730  on the optical axis, and TP 4  is a thickness of the fourth lens  740  on the optical axis. 
         [0219]    The optical image capturing system of the third preferred embodiment further satisfies ΣPP=f1+f2+f4=10.9940 mm and f1/(f1+f2+f4)=0.2801, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  710  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0220]    The optical image capturing system of the third preferred embodiment further satisfies ΣNP=f3=−2.6956 mm and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens. 
         [0221]    The parameters of the lenses of the third embodiment are listed in Table 13 and Table 14.

       Eighth Embodiment 
       [0224]    As shown in  FIG. 8A  and  FIG. 8B , an optical image capturing system of the third preferred embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture  800 , a first lens  810 , a second lens  820 , a third lens  880 , a fourth lens  840 , an infrared rays filter  870 , an image plane  880 , and an image sensor  890 . 
         [0225]    The first lens  810  has positive refractive power, and is made of plastic. An object-side surface  812  thereof, which faces the object side, is a convex aspheric surface, and an image-side surface  814  thereof, which faces the image side, is a concave aspheric surface, and the object-side surface  812  and the image-side surface  814  both have an inflection point respectively. 
         [0226]    The second lens  820  has negative refractive power, and is made of plastic. An object-side surface  822  thereof which faces the object side is a concave aspheric surface, and an image-side surface  824  thereof which faces the image side is a convex aspheric surface. 
         [0227]    The third lens  830  has positive refractive power, and is made of plastic. An object-side surface  832 , which faces the object side, is a concave aspheric surface, and an image-side surface  834 , which faces the image side, is a convex aspheric surface. The object-side surface  832  has two inflection points, while the image-side surface  834  has an inflection point. 
         [0228]    The fourth lens  840  has a negative refractive power, and is made of plastic. An object-side surface  842 , which faces the object side, is a convex aspheric surface, and an image-side surface  844 , which faces the image side, is a concave aspheric surface. The object-side surface  842  and the image-side surface  844  both have an inflection point respectively. 
         [0229]    The infrared rays filter  870  is made of glass, and between the fourth lens  840  and the image plane  880 . The infrared rays filter  870  gives no contribution to the focal length of the system. 
         [0230]    The parameters of the lenses of the third preferred embodiment are |f2|+|f3|=5.7651 mm; |f1|+|f4|=7.6347 mm; and |f2|+|f3|&lt;|f1|+|f4|, where f1 is a focal length of the first lens  810 ; f2 is a focal length of the second lens  820 ; f3 is a focal length of the third lens  830 ; and f4 is a focal length of the fourth lens  840 . 
         [0231]    The optical image capturing system of the third preferred embodiment further satisfies TP 3 =0.342 mm and TP 4 =0.876 mm, where TP 3  is a thickness of the third lens  830  on the optical axis, and TP 4  is a thickness of the fourth lens  840  on the optical axis. 
         [0232]    The optical image capturing system of the third preferred embodiment further satisfies ΣPP=f1+f2+f4=10.8016 mm and f1/(f1+f2+f4)=0.3169, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens  810  to other positive lenses to avoid the significant aberration caused by the incident rays. 
         [0233]    The optical image capturing system of the third preferred embodiment further satisfies ΣNP=f3=−2.598 mm and f3/(f3)=1, where ΣNP is a sum of the focal lengths of each negative lens. 
         [0234]    The parameters of the lenses of the third embodiment are listed in Table 15 and Table 16.
