54 1. SINGLE FOCUS OPTICAL IMAGE CAPTURING SYSTEM RELATED APPLICATIONS The application claims priority to Taiwan Application Serial Number , filed Jun. 26, 2012, which is herein incorporated by reference. BACKGROUND 1. Technical Field The present invention relates to a single focus optical image capturing system. More particularly, the present inven tion relates to a compact single focus optical image capturing system applicable to electronic products. 2. Description of Related Art In recent years, with the popularity of mobile products with camera functionalities, the demand of optical lens systems is increasing. The sensor of a conventional photographing cam era is typically a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor) sensor. As the advanced semiconductor manufacturing technologies have allowed the pixel size of sensors to be reduced and compact optical lens systems have gradually evolved toward the field of higher megapixels, there is an increasing demand for compact optical lens systems featuring better image qual ity. In an optical lens system, a TV distortion doesn t affect the image clarity but causes the image shape distortion. The TV distortion of a conventional fixed-focus camera is usually maintained within 3%. When the TV distortion is greater than 3%, it will be apparent to human eyes. However, the level of difficulty for maintaining the TV distortion increases with the size of the image. Furthermore, when a conventional fixed focus camera is employed for both close-up photographing and long distance photographing, the conventional fixed-fo cus camera can not offer the desired TV distortion for both close-up photographing and long distance photographing. The TV distortion condition of a conventional single focus camera is commonly designed for satisfying long distance photographing Such as the one disclosed in U.S. Pat. No. 8,000,031, as a result, a high TV distortion is generated for close-up photographing. The demand for close-up photo graphing increases rapidly nowadays, the aforementioned single focus camera no longer satisfies consumers. The TV distortion condition should be designed for satisfying both close-up photographing and long distance photographing, thus high image quality can be obtained for both close-up photographing and long distance photographing. SUMMARY According to one aspect of the present disclosure, a single focus optical image capturing system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element with positive refrac tive power has a convex object-side Surface. The second lens element has negative refractive power. The third lens element has refractive power. The fourth lens element with refractive power has an object-side Surface and an image-side Surface being aspheric. The fifth lens element with refractive power has a concave image-side surface, wherein an object-side surface and the image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflec tion point on at least one of the object-side Surface and the image-side surface thereof. When a TV distortion for close up photographing of the single focus optical image capturing system is TVDm, and a TV distortion for long distance pho tographing of the single focus optical image capturing system is TVDi, the following relationships are satisfied: TVDi-TVDm <1.5%; ITVDig1.5%; and According to another aspect of the present disclosure, a single focus optical image capturing system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens ele ment and a fifth lens element.

DETAILED DESCRIPTION A single focus optical image capturing system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The single focus optical image capturing system further includes an image sensor located on an image plane. The first lens element with positive refractive power has a convex object-side Surface and a concave image-side Surface, so that the total track length of the single focus optical image capturing system can be reduced by adjusting the positive refractive power of the first lens element. The second lens element has negative refractive power, so that the aberration generated from the first lens element with positive refractive power can be corrected effectively. The second lens element can have an image-side Surface being convex or concave. When the second lens element has the convex image-side Surface, the astigmatism of the single focus optical image capturing system can be corrected. When the second lens element has the concave image-side surface, the aberration generated from the first lens element can be further corrected. The third lens element can have positive or negative refrac tive power. When the third lens element has positive refractive power, the distribution of the refractive power of the first lens element can be balanced, so that the sensitivity of the single focus optical image capturing system can be reduced. When the third lens element with negative refractive power has a convex image-side Surface, the high order aberration of the single focus optical image capturing system can be reduced, and the astigmatism thereof can be corrected as well. The fourth lens element can have negative refractive power, so that the high order aberration of the single focus optical image capturing system can be further reduced. The fourth lens element can have a concave object-side Surface and a convex mage-side Surface. Therefore, the astigmatism of the single focus optical image capturing system can be further corrected. The fifth lens element can have negative refractive power, and can have a convex object-side Surface and a concave image-side Surface. Therefore, the principal point of the single focus optical image capturing system can be positioned away from the image plane, and the back focal length of the single focus optical image capturing system can be reduced So as to maintain the compact size of the single focus optical image capturing system. Furthermore, the fifth lens element can have at least one inflection point on at least one of the object-side Surface and the image-side Surface thereof. So that the incident angle of the off-axis field on the image plane can be effectively reduced, and the aberration of the off-axis field can be corrected. When the single focus optical image capturing system is for close-up photographing, an object distance (i.e. an axial distance between an object and the object-side surface of the first lens element) can be 100 mm, and a TV distortion for close-up photographing of the single focus optical image capturing system is TVDm; when the single focus optical image capturing system is for long distance photographing, the object distance can be mm, and a TV distortion for long distance photographing of the single focus optical image capturing system is TVDi, the following relationship is sat isfied: Therefore, high image quality can be obtained, and the difference between the image distortions resulted from dif ferent object distances thereof would not be excessive. TVDm and TVDican preferably satisfy the following rela tionship: TVDi-TVDn <1.0%. Moreover, TVDm and TVDi may satisfy the following relationship: When the TV distortion for long distance photographing of the single focus optical image capturing system is TVDi, the following relationship is satisfied: TVDi 31.5%. Therefore, the TV distortion for long distance photograph ing of the single focus optical image capturing system can be effectively controlled. TVDican preferably satisfy the following relationship: TVDi 31.0%. Moreover, TVDi may satisfy the following relationship: TVDi 30.5%. When the TV distortion for close-up photographing of the single focus optical image capturing system is TVDm, the following relationship is satisfied: TVDn <1.5%. TVDm can preferably satisfy the following relationship: TVDn <1.0%. When an axial distance between the object-side surface of the first lens element and the image plane is TTL, a maximum image height of the single focus optical image capturing system is ImgH, and a focal length of the single focus optical image capturing system is f, the following relationship is satisfied: 5.0 mm-ttlxf7imgh-7.0 mm. Therefore, the compact size of the single focus optical image capturing system can be maintained for applying to the thin and portable electronic product. TTL, ImgH and f can preferably satisfy the following rela tionship: 5.5 mm-ttlxf7imgh-6.5 mm.

57 7 When a height of an imaging area of the image sensor is V. and a width of the imaging area of the image sensor is H, the following relationships are satisfied: 3.0 mm-v<4.5 mm; and 4.0 mm3h36.0 mm. Therefore, the size of an image is maintained for obtaining the propertv distortion for close-up photographing and long distance photographing. Consequently, the image quality can be well controlled. When a curvature radius of the object-side surface of the fourth lens element is R7, and a curvature radius of the image side surface of the fourth lens element is R8, the following relationship is satisfied: Therefore, the astigmatism of the single focus optical image capturing system can be corrected by adjusting the curvatures of the surfaces of the fourth lens element. When an Abbe number of the second lens element is V2, an Abbe number of the third lens element is V3, and an Abbe number of the fourth lens element is V4, the following rela tionship is satisfied: Therefore, the chromatic aberration of the single focus optical image capturing system can be corrected. When a central thickness of the fourth lens element is CT4, and a central thickness of the fifth lens element is CT5, the following relationship is satisfied: Therefore, the thickness of the fourth lens element and the fifth lens element are proper for the manufacture and the assembling of the single focus optical image capturing sys tem. When a curvature radius of an object-side surface of the second lens element is R3, and a curvature radius of the image-side Surface of the second lens element is R4, the following relationship is satisfied: Therefore, the negative refractive power of the second lens element is proper by adjusting the curvatures of the Surfaces of the second lens element, and the aberration generated from the first lens element with positive refractive power can be further corrected. When the focal length of the single focus optical image capturing system is f, a focal length of the first lens element is f1, a focal length of the second lens element is f2, a focal length of the third lens element is f3, a focal length of the fourth lens element is f4, and a focal length of the fifth lens element is fis, the following relationship is satisfied: Therefore, the refractive power of the fourth lens element and the fifth lens element are proper for correcting the high order aberration of the single focus optical image capturing system effectively. According to the single focus optical image capturing sys tem of the present disclosure, the lens elements thereof can be made of plastic or glass material. When the lens elements are made of glass material, the distribution of the refractive power of the single focus optical image capturing system may be more flexible to design. When the lens elements are made of plastic material, the costs of manufacture can be effectively reduced. Furthermore, the surfaces of each lens element can be aspheric, so that it is easier to make the Surface into non-spherical shapes. As a result, more controllable variables are obtained, and the aberration is reduced, as well as the number of required lens elements can be reduced while con structing an optical system. Therefore, the total track length of the single focus optical image capturing system can also be reduced. According to the single focus optical image capturing sys tem of the present disclosure when a lens element has a convex surface, it indicates that the paraxial region of the Surface is convex; when the lens element has a concave Sur face, it indicates that the paraxial region of the Surface is COCaV. According to the single focus optical image capturing sys tem of the present disclosure, the single focus optical image capturing system can include at least one stop. Such as an aperture stop, a glare stop, or a field stop, etc. Said glare stop or said field stop is allocated for reducing stray light while retaining high image quality. Furthermore, when the stop is an aperture stop, the position of the aperture stop within an optical system can be arbitrarily placed in front of the entire optical system, or in front of the image plane within the optical system in accordance with the preference of an optical designer, in order to achieve the desirable optical features or higher image quality produced from the optical system. According to the single focus optical image capturing sys tem of the present disclosure, the single focus optical image capturing system is featured with good correcting ability and high image quality, and can be applied to 3D (three-dimen sional) image capturing field.
