     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. 
     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 large aperture of an end user, like functionality of micro filming and night view, and a wide angle of an end user, like self-shooting function of a preset lens, of the portable electronic device have been raised. The optical image capturing system with large aperture value usually has a problem with lots of aberrations, resulting in the worse of image quality for the image formation and the difficulty of manufacturing the optical image capturing system. The optical image capturing system with wide-angle designs may be faced with a problem of increasing distortion.

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 sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relation is satisfied: ΣPP=f2+f4+f5=10.59517 mm and f2/(f2+f4+f5)=0.343240363. Hereby, it&#39;s favorable for allocating the positive refractive power of the second lens element  220  to others convex lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed. 
     In the second embodiment of the optical image capturing system, focal lengths of the first lens element  210 , the third lens element  230 , and the sixth lens element  260  are f1, f3, and f6, respectively. A sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relation is satisfied: ΣNP=f1+f3+f6=−8.56404 mm and f1/(f1+f3+f6)=0.287991415. Hereby, it&#39;s favorable for allocating the negative refractive power of the first lens element  210  to others concave lens elements. 
     In the second embodiment of the optical image capturing system, a distance perpendicular to the optical axis between a critical point on the object-side surface  252  of the fifth lens element and the optical axis is HVT51. A distance perpendicular to the optical axis between a critical point on the image-side surface  254  of the fifth lens element and the optical axis is HVT52. The following relation is satisfied: HVT51=0 mm and HVT52=0 mm. 
     A distance in parallel with an optical axis from an inflection point to an axial point on the object-side surface  252  of the fifth lens element is Inf51. A distance in parallel with an optical axis from an inflection point to an axial point on the image-side surface  254  of the fifth lens element is Inf52. The following relation is satisfied: Inf51=0 mm and Inf52=0 mm.
