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. 
         [0006]    The traditional optical image capturing system of a portable electronic device comes with different designs, including a four-lens or a five-lens design. However, the requirement for the higher resolution and imaging quality and the requirement for a largest aperture of an end user, like functionalities of micro filming and night view, of the portable electronic device have been raised. The optical image capturing system in prior arts cannot meet the requirement of the higher order camera lens module. 
         [0007]    Therefore, an optical imaging system capable of increasing an incoming light quantity of optical system as well as improving the image quality becomes an important issue.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0049]    Reference will now be made in detail to the exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Therefore, it is to be understood that the foregoing is illustrative of exemplary embodiments and is not to be construed as limited to the specific embodiments disclosed, and that modifications to the disclosed exemplary embodiments, as well as other exemplary embodiments, are intended to be included within the scope of the appended claims. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept to those skilled in the art. The relative proportions and ratios of elements in the drawings may be exaggerated or diminished in size for the sake of clarity and convenience in the drawings, and such arbitrary proportions are only illustrative and not limiting in any way. The same reference numbers are used in the drawings and the description to refer to the same or like parts. 
         [0050]    It will be understood that, although the terms ‘first’, ‘second’, ‘third’, etc., may be used herein to describe various elements, these elements should not be limited by these terms. The terms are used only for the purpose of distinguishing one component from another component. Thus, a first element discussed below could be termed a second element without departing from the teachings of embodiments. As used herein, the term “or” includes any and all combinations of one or more of the associated listed items. 
         [0051]    An optical image capturing system, in order from an object side to an image side, includes a first lens element with a refractive power, a second lens element with a refractive power, a third lens element with a refractive power, a fourth lens element with a refractive power, a fifth lens element with a refractive power, a sixth lens element with a refractive power, and a seventh lens element with a refractive power. The optical image capturing system may further include an image sensing device which is disposed on an image plane. 
         [0052]    A ratio of the focal length f of the optical image capturing system to a focal length fp of each of lens elements with the positive refractive power is PPR. A ratio of the focal length f of the optical image capturing system to a focal length fn of each of lens elements with a negative refractive power is NPR. A sum of the PPR of all lens elements with a positive refractive power is ΣPPR. A sum of the NPR of all lens elements with a negative refractive power is ΣNPR. It is beneficial to control the total refractive power and the total length of the optical image capturing system when following conditions are satisfied: 0.5≦ΣPPR/|ΣNPR|≦2. 
         [0053]    The first lens element may have a positive refractive power and a concave image-side surface and has a convex object-side surface. Thus, the strength of the positive refractive power of the first lens element can be fine-tuned to reduce the total length of the optical image capturing system. 
         [0054]    The second lens element may have a negative refractive power, a convex object-side surface and a concave image-side surface. Hereby, the aberration generated by the first lens element can be corrected. 
         [0055]    The third lens element may have a positive refractive power and a convex image-side surface. Hereby, the positive refractive power of the first lens element can be shared, so as to avoid the longitudinal spherical aberration to increase abnormally and to decrease the sensitivity of the optical image capturing system. 
         [0056]    The fourth lens element may have a negative refractive power, a concave object-side surface and a convex image-side surface. Hereby, the astigmatic can be corrected, such that the image surface will become smoother. 
         [0057]    The fifth lens element may have a positive refractive power and at least one of the object-side and the image-side surfaces of the fifth lens element may have at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the fifth lens element effectively. 
         [0058]    The sixth lens element may have a positive refractive power and at least one of the object-side and the image-side surfaces of the sixth lens element may have at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element effectively. 
         [0059]    The seventh lens element with a negative refractive power may have a concave image-side surface. Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. In addition, at least one of the object-side and the image-side surfaces of the seventh lens elements may have at least one inflection point, such that the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0060]    The optical image capturing system may further include an image sensing device which is disposed on an image plane. Half of a diagonal of an effective detection field of the image sensing device (imaging height or the maximum image height of the optical image capturing system) is HOI. A distance from the object side surface of the first lens element to the image plane on the optical axis is HOS. The following relation is satisfied: HOS/HOI≦7 and 0.5≦HOS/f≦2.5. Hereby, the miniaturization of the optical image capturing system can be maintained effectively, so as to be carried by lightweight portable electronic devices. 
         [0061]    In addition, in the optical image capturing system of the disclosure, according to different requirements, at least one aperture stops may be arranged for reducing stray light and improving the image quality. 
         [0062]    In the optical image capturing system of the disclosure, the aperture stop may be a front or middle aperture. The front aperture is the aperture stop between a photographed object and the first lens element. The middle aperture is the aperture stop between the first lens element and the image plane. If the aperture stop is the front aperture, a longer distance between the exit pupil and the image plane of the optical image capturing system can be formed, such that more optical elements can be disposed in the optical image capturing system and the effect of receiving images of the image sensing device can be raised. If the aperture stop is the middle aperture, the view angle of the optical image capturing system can be expended, such that the optical image capturing system has the same advantage that is owned by wide angle cameras. A distance from the aperture stop to the image-side surface of the sixth lens element is InS. The following relation is satisfied: 0.5≦InS/HOS≦1.1. Hereby, features of maintaining the minimization for the optical image capturing system and having wide-angle are available simultaneously. 
         [0063]    In the optical image capturing system of the disclosure, a distance from the object-side surface of the first lens element to the image-side surface of the seventh lens element is InTL. A total central thickness of all lens elements with refractive powers on the optical axis is ΣTP. The following relation is satisfied: 0.1≦ΣTP/InTL≦0.9. Hereby, contrast ratio for the image formation in the optical image capturing system and defect-free rate for manufacturing the lens element can be given consideration simultaneously, and a proper back focal length is provided to dispose others optical components in the optical image capturing system. 
         [0064]    A curvature radius of the object-side surface of the first lens element is R1. A curvature radius of the image-side surface of the first lens element is R2. The following relation is satisfied: 0.01&lt;|R1/R2|&lt;20.

Preferably, the following relation is satisfied: 0.05&lt;|R1/R2|&lt;0.3. 
         [0065]    A curvature radius of the object-side surface of the seventh lens element is R13. A curvature radius of the image-side surface of the seventh lens element is R14. The following relation is satisfied: −7&lt;(R13−R14)/(R13+R14)&lt;2. Hereby, the astigmatic generated by the optical image capturing system can be corrected beneficially. 
         [0066]    A distance between the first lens element and the second lens element on the optical axis is IN12. The following relation is satisfied: IN12/f&lt;0.2. Hereby, the aberration of the lens elements can be improved, such that the performance can be increased. 
         [0067]    Central thicknesses of the first lens element and the second lens element on the optical axis are TP1 and TP2, respectively. The following relation is satisfied: 0.8≦(TP1+IN12)/TP2≦6.0. Hereby, the sensitivity produced by the optical image capturing system can be controlled, such that the performance can be increased. 
         [0068]    Central thicknesses of the sixth lens element and the seventh lens element on the optical axis are TP6 and TP7, respectively, and a distance between the sixth lens element and the seventh lens element on the optical axis is IN67. The following relation is satisfied: 0.8≦(TP7+IN67)/TP6≦3. Hereby, the sensitivity produced by the optical image capturing system can be controlled and the total height of the optical image capturing system can be reduced. 
         [0069]    Central thicknesses of the third lens element, the fourth lens element, and the fifth lens element on the optical axis are TP3, TP4, and TP5, respectively. A distance between the third lens element and the fourth lens element on the optical axis is IN34. A distance between the fourth lens element and the fifth lens element on the optical axis is IN45. A distance from the object-side surface of the first lens element to the image-side surface of the seventh lens element is InTL. The following relation is satisfied: 0.1≦(TP3+TP4+TP5)/ΣTP≦0.6. Hereby, the aberration generated by the process of moving the incident light can be adjusted slightly layer upon layer, and the total height of the optical image capturing system can be reduced.

A distance perpendicular to the optical axis between a critical point on the image-side surface of the sixth lens element and the optical axis is HVT62. The following relation is satisfied: 0≦HVT61/HVT62. Hereby, the aberration of the off-axis view field can be corrected effectively.

         [0077]    The following relation is satisfied for the optical image capturing system of the present disclosure: 1≦|InRS62|+|InRS71|≦5. Hereby, a distance of a maximum effective diameter position between the sixth lens element and the seventh lens element can be controlled. Thus, it&#39;s favorable for correcting the aberration of surrounding view field for the optical image capturing system and for maintaining the minimization for the optical image capturing system. 
         [0078]    The following relation is satisfied for the optical image capturing system of the disclosure: 0≦Inf72/|InRS72|≦2. A depth of the maximum effective diameter and positions of appearing inflection points on the image-side surface of the seventh lens element can be controlled. Thus, it&#39;s favorable for correcting the aberration of off-axis view field and maintaining the minimization for the optical image capturing system effectively. 
         [0079]    In one embodiment of the optical image capturing system of the present disclosure, the chromatic aberration of the optical image capturing system can be corrected by staggering the lens element with high dispersion coefficient and the lens element with low dispersion coefficient. 
         [0080]    The above Aspheric formula is: z=ch 2 /[1+[1−(k+1)c 2 h 2 ] 0.5 ]+A4h 4 +A6h 6 +A8h 8 +A10h 10 +A12h 12 +A14h 14 +A16h 16 +A18h 18 +A20h 20 + . . .

         [0081]    The optical image capturing system provided by the disclosure, the lens elements may be made of glass or plastic material. If plastic material is adopted to produce the lens elements, the cost of manufacturing will be lowered effectively. If lens elements are made of glass, the heat effect can be controlled and the designed space arranged for the refractive power of the optical image capturing system can be increased. Besides, the object-side surface and the image-side surface of the first through seventh lens elements may be aspheric, so as to obtain more control variables. Comparing with the usage of traditional lens element made by glass, the number of using lens elements can be reduced and the aberration can be eliminated. Therefore, the total height of the optical image capturing system can be reduced effectively. 
         [0082]    In addition, in the optical image capturing system provided of the disclosure, the lens element has a convex surface if the surface of the lens element is convex adjacent to the optical axis. The lens element has a concave surface if the surface of the lens element is concaving adjacent to the optical axis.

With the features of a good aberration correction and a high quality of image formation, the optical image capturing system can be used in various application fields.

       [0124]    Please refer to  FIG. 2A ,  FIG. 2B , and  FIG. 2C ,  FIG. 2A  is a schematic view of the optical image capturing system according to the second embodiment of the present application,  FIG. 2B  is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the second embodiment of the present application, and  FIG. 2C  is a TV distortion grid of the optical image capturing system according to the second embodiment of the present application. As shown in  FIG. 2A , in order from an object side to an image side, the optical image capturing system includes an aperture stop  200 , a first lens element  210 , a second lens element  220 , a third lens element  230 , a fourth lens element  240 , a fifth lens element  250 , a sixth lens element  260 , a seventh lens element  270 , an IR-bandstop filter  280 , an image plane  290 , and an image sensing device  292 . 
         [0125]    The first lens element  210  has a positive refractive power and it is made of plastic material. The first lens element  210  has a convex object-side surface  212  and a convex image-side surface  214 , and both of the object-side surface  212  and the image-side surface  214  are aspheric. 
         [0126]    The second lens element  220  has a negative refractive power and it is made of plastic material. The second lens element  220  has a convex object-side surface  222  and a concave image-side surface  224 , and both of the object-side surface  222  and the image-side surface  224  are aspheric. 
         [0127]    The third lens element  230  has a negative refractive power and it is made of plastic material. The third lens element  230  has a concave object-side surface  232  and a concave image-side surface  234 , and both of the object-side surface  232  and the image-side surface  234  are aspheric. 
         [0128]    The fourth lens element  240  has a positive refractive power and it is made of plastic material. The fourth lens element  240  has a concave object-side surface  242  and a convex image-side surface  244 , and both of the object-side surface  242  and the image-side surface  244  are aspheric. 
         [0129]    The fifth lens element  250  has a positive refractive power and it is made of plastic material. The fifth lens element  250  has a convex object-side surface  252  and a concave image-side surface  254 . Both of the object-side surface  252  and the image-side surface  254  are aspheric, and the image-side surface  254  has inflection points. 
         [0130]    The sixth lens element  260  has a positive refractive power and it is made of plastic material. The sixth lens element  260  has a concave object-side surface  262  and a convex image-side surface  264 , and the object-side surface  262  of the sixth lens element has at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element  260  effectively. 
         [0131]    The seventh lens element  270  has a negative refractive power and it is made of plastic material. The seventh lens element  270  has a convex object-side surface  272  and a concave image-side surface  274 . Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. Besides, the image-side surface  274  of the seventh lens elements has at least one inflection point, and the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0132]    The IR-bandstop filter  280  is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the seventh lens element  270  and the image plane  290 . 
         [0133]    In the second embodiment of the optical image capturing system, focal lengths of the second lens element  220 , the third lens element  230 , the fourth lens element  240 , the fifth lens element  250 , and the sixth lens element  260  are f2, f3, f4, f5, and f6, respectively. The following relation is satisfied: |f2|+|f3|+|f4|+|f5|+|f6|=51.9801, |f1|+|f7|=8.6420, and |f2|+|f3|+|f4|+|f5|+|f6|&gt;|f1|+|f7|. 
         [0134]    In the second embodiment of the optical image capturing system, a central thickness of the sixth lens element  260  on the optical axis is TP6. A central thickness of the seventh lens element  270  on the optical axis is TP7. The following relation is satisfied: TP6=0.9525 mm and TP7=0.4852 mm. 
         [0135]    In the second embodiment of the optical image capturing system, the first lens element  210 , the fourth lens element  240 , the fifth lens element  250 , and the sixth lens element  260  are convex lens elements, and focal lengths of each of them are f1, f4, f5, and f6, respectively. A sum of focal lengths of all lens elements with a positive refractive power is ΣPP. The following relation is satisfied: ΣPP=f1+f4+f5+f6=35.8351 mm and f1/(f1+f4+f5+f6)=0.1647. Hereby, it&#39;s favorable for allocating the positive refractive power of the first lens element  210  to others convex lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0136]    In the second embodiment of the optical image capturing system, focal lengths of the second lens element  220 , the third lens element  230 , and the seventh lens element  270  are f2, f3, and f7, respectively. A sum of focal lengths of all lens elements with a negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f2+f3+f7=−24.7870 mm, and f7/(f2+f3+f7)=0.1106. Hereby, it&#39;s favorable for allocating the negative refractive power of the seventh lens element to others concave lens elements.

The third lens element  330  has a convex object-side surface  332  and a convex image-side surface  334 , and both of the object-side surface  332  and the image-side surface  334  are aspheric. 
         [0146]    The fourth lens element  340  has a positive refractive power and it is made of plastic material. The fourth lens element  340  has a convex object-side surface  342  and a concave image-side surface  344 , and both of the object-side surface  342  and the image-side surface  344  are aspheric. 
         [0147]    The fifth lens element  350  has a positive refractive power and it is made of plastic material. The fifth lens element  350  has a convex object-side surface  352  and a convex image-side surface  354 . Both of the object-side surface  352  and the image-side surface  354  are aspheric, and the object-side surface  352  has inflection points. 
         [0148]    The sixth lens element  360  has a negative refractive power and it is made of plastic material. The sixth lens element  360  has a concave object-side surface  362  and a convex image-side surface  364 , and the object-side surface  362  of the sixth lens element has at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element  360  effectively. 
         [0149]    The seventh lens element  370  has a negative refractive power and it is made of plastic material. The seventh lens element  370  has a concave object-side surface  372  and a concave image-side surface  374 . Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. Besides, the image-side surface  374  of the seventh lens elements has at least one inflection point, and the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0150]    The IR-bandstop filter  380  is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the seventh lens element  370  and the image plane  390 . 
         [0151]    In the third embodiment of the optical image capturing system, focal lengths of the second lens element  320 , the third lens element  330 , the fourth lens element  340 , the fifth lens element  350 , and the sixth lens element  350  are f2, f3, f4, f5, and f6, respectively. The following relation is satisfied: |f2|+|f3|+|f4|+|f5|+|f6|=53.9016, |f1|+|f7|=9.0440, and |f2|+|f3|+|f4|+|f5|+|f6|&gt;|f1|+|f7|. 
         [0152]    In the third embodiment of the optical image capturing system, a central thickness of the sixth lens element  360  on the optical axis is TP6. A central thickness of the seventh lens element  370  on the optical axis is TP7. The following relation is satisfied: TP6=0.3549 mm and TP7=0.3521 mm. 
         [0153]    In the third embodiment of the optical image capturing system, focal lengths of the first lens element  310 , the third lens element  330 , the fourth lens element  340 , and the fifth lens element  350  are f1, f3, f4, and f5, respectively. A sum of focal lengths of all lens elements with a positive refractive power is τPP. The following relation is satisfied: ΣPP=f1+f3+f4+f5=44.4613 mm and f1/(f1+f3+f4+f5)=0.1136 mm. Hereby, it&#39;s favorable for allocating the positive refractive power of the first lens element  310  to others convex lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0154]    In the third embodiment of the optical image capturing system, focal lengths of the second lens element  320 , the sixth lens element  360 , and the seventh lens element  370  are f2, f6, and f7, respectively. A sum of focal lengths of all lens elements with a negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f2+f6+f7=−18.4843 mm and f7/(f2+f6+f7)=0.2160. Hereby, it&#39;s favorable for allocating the negative refractive power of the seventh lens element to others concave lens elements. 
         [0155]    Please refer to the following Table 5 and Table 6. 
         [0156]    The detailed data of the optical image capturing system of the third embodiment is as shown in Table 5.

       The Fourth Embodiment 
     Embodiment 4 
       [0160]    Please refer to  FIG. 4A ,  FIG. 4B , and  FIG. 4C ,  FIG. 4A  is a schematic view of the optical image capturing system according to the fourth embodiment of the present application,  FIG. 4B  is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the fourth embodiment of the present application, and  FIG. 4C  is a TV distortion grid of the optical image capturing system according to the fourth embodiment of the present application. As shown in  FIG. 4A , in order from an object side to an image side, the optical image capturing system includes an aperture stop  400 , a first lens element  410 , a second lens element  420 , a third lens element  430 , a fourth lens element  440 , a fifth lens element  450 , a sixth lens element  460 , a seventh lens element  470 , an IR-bandstop filter  480 , an image plane  490 , and an image sensing device  492 . 
         [0161]    The first lens element  410  has a positive refractive power and it is made of plastic material. The first lens element  410  has a convex object-side surface  412  and a concave image-side surface  414 , and both of the object-side surface  412  and the image-side surface  414  are aspheric. 
         [0162]    The second lens element  420  has a negative refractive power and it is made of plastic material. The second lens element  420  has a convex object-side surface  422  and a concave image-side surface  424 , and both of the object-side surface  422  and the image-side surface  424  are aspheric. 
         [0163]    The third lens element  430  has a positive refractive power and it is made of plastic material. The third lens element  430  has a concave object-side surface  432  and a convex image-side surface  434 , and both of the object-side surface  432  and the image-side surface  434  are aspheric. 
         [0164]    The fourth lens element  440  has a negative refractive power and it is made of plastic material. The fourth lens element  440  has a convex object-side surface  442  and a concave image-side surface  444 , and both of the object-side surface  442  and the image-side surface  444  are aspheric. 
         [0165]    The fifth lens element  450  has a negative refractive power and it is made of plastic material. The fifth lens element  450  has a convex object-side surface  452  and a concave image-side surface  454 , and both of the object-side surface  452  and the image-side surface  454  are aspheric. 
         [0166]    The sixth lens element  460  may have a positive refractive power and it is made of plastic material. The sixth lens element  460  has a concave object-side surface  462  and a convex image-side surface  464 , and at least one of the object-side and the image-side surfaces of the sixth lens elements  460  may have at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element  460  effectively. 
         [0167]    The seventh lens element  470  has a negative refractive power and it is made of plastic material. The seventh lens element  470  has a concave object-side surface  472  and a concave image-side surface  474 . Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. Besides, the image-side surface  474  of the seventh lens elements has at least one inflection point, and the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0168]    The IR-bandstop filter  480  is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the seventh lens element  470  and the image plane  490 . 
         [0169]    In the fourth embodiment of the optical image capturing system, focal lengths of the second lens element  420 , the third lens element  430 , the fourth lens element  440 , the fifth lens element  450 , and the sixth lens element  460  are f2, f3, f4, f5, and f6, respectively. The following relation is satisfied: |f2|+|f3|+|f4|+|f5|+f6|=472.6722 mm, |f1|+|f7|=7.1716 mm, and |f2|+|f3|+|f4|+|f5|+|f6|&gt;|f1|+|f7|. 
         [0170]    In the fourth embodiment of the optical image capturing system, a central thickness of the sixth lens element  460  on the optical axis is TP6. A central thickness of the seventh lens element  470  on the optical axis is TP7. The following relation is satisfied: TP6=0.6737 mm and TP7=0.4780 mm. 
         [0171]    In the fourth embodiment of the optical image capturing system, focal lengths of the first lens element  410 , the third lens element  430 , and the sixth lens element  460  are f1, f3, and f6, respectively. A sum of focal lengths of all lens elements with a positive refractive power is ΣPP. The following relation is satisfied: ΣPP=f1+f3+f6=17.4258 mm and f1/(f1+f3+f6)=0.2264. Hereby, it&#39;s favorable for allocating the positive refractive power of the first lens element  410  to others convex lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0172]    In the fourth embodiment of the optical image capturing system, focal lengths of the second lens element  420 , the fourth lens element  440 , the fifth lens element  450 , and the seventh lens element  470  are f2, f4, f5, and f7, respectively. A sum of focal lengths of all lens elements with a negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f2+f4+f5+f7=−460.1883 mm and f7/(f2+f4+f5+f7)=0.0069. Hereby, it&#39;s favorable for allocating the negative refractive power of the seventh lens element to others concave lens elements. 
         [0173]    Please refer to the following Table 7 and Table 8. 
         [0174]    The detailed data of the optical image capturing system of the fourth embodiment is as shown in Table 7.

       The Fifth Embodiment 
     Embodiment 5 
       [0178]    Please refer to  FIG. 5A ,  FIG. 5B , and  FIG. 5C ,  FIG. 5A  is a schematic view of the optical image capturing system according to the fifth embodiment of the present application,  FIG. 5B  is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the fifth embodiment of the present application, and  FIG. 5C  is a TV distortion grid of the optical image capturing system according to the fifth embodiment of the present application. As shown in  FIG. 5A , in order from an object side to an image side, the optical image capturing system includes an aperture stop  500 , a first lens element  510 , a second lens element  520 , a third lens element  530 , a fourth lens element  540 , a fifth lens element  550 , a sixth lens element  560 , a seventh lens element  570 , an IR-bandstop filter  580 , an image plane  590 , and an image sensing device  592 . 
         [0179]    The first lens element  510  has a positive refractive power and it is made of plastic material. The firth lens element  510  has a convex object-side surface  512  and a concave image-side surface  514 , and both of the object-side surface  512  and the image-side surface  514  are aspheric. 
         [0180]    The second lens element  520  has a negative refractive power and it is made of plastic material. The second lens element  520  has a convex object-side surface  522  and a concave image-side surface  524 , and both of the object-side surface  522  and the image-side surface  524  are aspheric. 
         [0181]    The third lens element  530  has a positive refractive power and it is made of plastic material. The third lens element  530  has a concave object-side surface  532  and a convex image-side surface  534 , and both of the object-side surface  532  and the image-side surface  534  are aspheric. 
         [0182]    The fourth lens element  540  has a negative refractive power and it is made of plastic material. The fourth lens element  540  has a convex object-side surface  542  and a concave image-side surface  544 , and both of the object-side surface  542  and the image-side surface  544  are aspheric. 
         [0183]    The fifth lens element  550  has a positive refractive power and it is made of plastic material. The fifth lens element  550  has a convex object-side surface  552  and a concave image-side surface  554 , and both of the object-side surface  552  and the image-side surface  554  are aspheric. 
         [0184]    The sixth lens element  560  may have a positive refractive power and it is made of plastic material. The sixth lens element  560  has a concave object-side surface  562  and a concave image-side surface  564 , and the object-side surface  562  of the sixth lens element  560  has at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element  560  effectively. 
         [0185]    The seventh lens element  570  has a negative refractive power and it is made of plastic material. The seventh lens element  570  has a convex object-side surface  572  and a concave image-side surface  574 . Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. Besides, the image-side surface  574  of the seventh lens elements has at least one inflection point, and the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0186]    The IR-bandstop filter  580  is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the seventh lens element  570  and the image plane  590 . 
         [0187]    In the fifth embodiment of the optical image capturing system, focal lengths of the second lens element  520 , the third lens element  530 , the fourth lens element  540 , the fifth lens element  550 , and the sixth lens element  560  are f2, f3, f4, f5, and f6, respectively. The following relation is satisfied: |f2|+|f3|+|f4|+|f5|+|f6|=116.2046 mm, |f1|+|f7|=6.0808 mm, and |f2|+|f3|+|f4|+|f5|+|f6|&gt;|f1|+|f7|. 
         [0188]    In the fifth embodiment of the optical image capturing system, a central thickness of the sixth lens element  560  on the optical axis is TP6. A central thickness of the seventh lens element  570  on the optical axis is TP7. The following relation is satisfied: TP6=0.5304 mm and TP7=0.4476 mm. 
         [0189]    In the fifth embodiment of the optical image capturing system, focal lengths of the first lens element  510 , the third lens element  530 , the fifth lens element  550 , and the sixth lens element  560  are f1, f3, f5, and f6, respectively. A sum of focal lengths of all lens elements with a positive refractive power is ΣPP. The following relation is satisfied: ΣPP=f1+f3+f5+f=81.4756 mm and f1/(f1+f3+f5+f6)=0.0413. Hereby, it&#39;s favorable for allocating the positive refractive power of the first lens element  510  to others convex lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0190]    In the fifth embodiment of the optical image capturing system, focal lengths of the second lens element  520 , the fourth lens element  540 , and the seventh lens element  570  are f2, f4, and f7, respectively. A sum of focal lengths of all lens elements with a negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f2+f4+f7=−41.2341 mm and f7/(f2+f4+f7)=0.0658. Hereby, it&#39;s favorable for allocating the negative refractive power of the seventh lens element to others concave lens elements. 
         [0191]    Please refer to the following Table 9 and Table 10. 
         [0192]    The detailed data of the optical image capturing system of the fourth embodiment is as shown in Table 9.

       The Sixth Embodiment 
     Embodiment 6 
       [0196]    Please refer to  FIG. 6A ,  FIG. 6B , and  FIG. 6C ,  FIG. 6A  is a schematic view of the optical image capturing system according to the sixth embodiment of the present application,  FIG. 6B  is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the sixth embodiment of the present application, and  FIG. 6C  is a TV distortion grid of the optical image capturing system according to the sixth embodiment of the present application. As shown in  FIG. 6A , in order from an object side to an image side, the optical image capturing system includes an aperture stop  600 , a first lens element  610 , a second lens element  620 , a third lens element  630 , a fourth lens element  640 , a fifth lens element  650 , a sixth lens element  660 , a seventh lens element  670 , an IR-bandstop filter  680 , an image plane  690 , and an image sensing device  692 . 
         [0197]    The first lens element  610  has a negative refractive power and it is made of plastic material. The first lens element  610  has a concave object-side surface  612  and a convex image-side surface  614 , and both of the object-side surface  612  and the image-side surface  614  are aspheric. 
         [0198]    The second lens element  620  has a positive refractive power and it is made of plastic material. The second lens element  620  has a concave object-side surface  622  and a convex image-side surface  624 , and both of the object-side surface  622  and the image-side surface  624  are aspheric. 
         [0199]    The third lens element  630  has a negative refractive power and it is made of plastic material. The third lens element  630  has a concave object-side surface  632  and a convex image-side surface  634 , and both of the object-side surface  632  and the image-side surface  634  are aspheric. 
         [0200]    The fourth lens element  640  has a positive refractive power and it is made of plastic material. The fourth lens element  640  has a convex object-side surface  642  and a convex image-side surface  644 , and both of the object-side surface  642  and the image-side surface  644  are aspheric. 
         [0201]    The fifth lens element  650  has a negative refractive power and it is made of plastic material. The fifth lens element  650  has a convex object-side surface  652  and a concave image-side surface  654 , and both of the object-side surface  652  and the image-side surface  654  are aspheric. 
         [0202]    The sixth lens element  660  has a positive refractive power and it is made of plastic material. The sixth lens element  660  has a convex object-side surface  662  and a convex image-side surface  664 , and the object-side surface  662  of the sixth lens element  660  has at least one inflection point. Hereby, the spherical aberration can be improved by adjusting the angle of incidence from each view field to the sixth lens element  660  effectively. 
         [0203]    The seventh lens element  670  has a negative refractive power and it is made of plastic material. The seventh lens element  670  has a concave object-side surface  672  and a convex image-side surface  674 . Hereby, the back focal length is reduced for maintaining the miniaturization, so as to miniaturize the lens element effectively. In addition, at least one of the object-side and the image-side surfaces of the seventh lens elements  670  may have at least one inflection point, and the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further. 
         [0204]    The IR-bandstop filter  680  is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the seventh lens element  670  and the image plane  690 . 
         [0205]    In the sixth embodiment of the optical image capturing system, focal lengths of the second lens element  620 , the third lens element  630 , the fourth lens element  640 , the fifth lens element  650 , and the sixth lens element  660  are f2, f3, f4, f5, and f6, respectively. The following relation is satisfied: |f2|+|f3|+|f4|+|f5|+|f6|=86.3084 mm and |f1|+|f7|=246.7079 mm. 
         [0206]    In the sixth embodiment of the optical image capturing system, a central thickness of the sixth lens element  660  on the optical axis is TP6. A central thickness of the seventh lens element  670  on the optical axis is TP7. The following relation is satisfied: TP6=1.3445 mm and TP7=0.2466 mm. 
         [0207]    In the sixth embodiment of the optical image capturing system, focal lengths of the second lens element  620 , the fourth lens element  640 , and the sixth lens element  660  are f2, f4, and f6, respectively. A sum of focal lengths of all lens elements with a positive refractive power is ΣPP. The following relation is satisfied: ΣPP=f2+f4+f6=22.6888 mm and f2/(f2+f4+f6)=0.3982. Hereby, it&#39;s favorable for allocating the positive refractive power of the first lens element  610  to others convex lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0208]    In the sixth embodiment of the optical image capturing system, focal lengths of the first lens element  610 , the third lens element  630 , the fifth lens element  650 , and the seventh lens element  670  are f1, f3, f5, and f7, respectively. A sum of focal lengths of all lens elements with a negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f1+f3+f5+f7=−310.3275 mm and f7/(f1+f3+f5+f7)=0.0181. Hereby, it&#39;s favorable for allocating the negative refractive power of the seventh lens element to others concave lens elements, and the significant aberrations generated in the process of moving the incident light can be suppressed. 
         [0209]    Please refer to the following Table 11 and Table 12. 
         [0210]    The detailed data of the optical image capturing system of the fourth embodiment is as shown in Table 11.
