     Description of Related Art 
     In recent years, vehicle recording cameras, such as dashcams are becoming more and more popular. The vehicle recording cameras enable drivers to provide video evidence from when they get involved in an accident. Furthermore, the rear-view cameras enable drivers to reverse their vehicles easier and avoid accidents. 
     A conventional optical system employed in a vehicle recording camera mainly adopts a structure with five or less lens elements. However, the conventional optical systems are not favorable for resolving power. Moreover, the surface shape of the lens elements and arrangement of refractive powers are also not favorable for correcting image distortion in a peripheral region and sufficient illumination. As a result, since the vehicle recording cameras focus on the image quality, the conventional optical system cannot satisfy this requirement.

     DETAILED DESCRIPTION 
     An image capturing lens assembly 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, a fifth lens element, and a sixth lens element. The image capturing lens assembly has a total of six lens elements with refractive power. 
     The first lens element has negative refractive power, so that it is favorable for enlarging the field of view to capture more of the image scene. The first lens element can have an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, so that it is favorable for reducing the astigmatism. 
     The second lens element can have an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. Therefore, it is favorable for correcting the astigmatism. 
     The fourth lens element has positive refractive power. Therefore, it is favorable for reducing spherical aberration. 
     The fifth lens element with negative refractive power can have an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. Therefore, it is favorable for improving the resolving power. Moreover, the image-side surface of the fifth lens element can have at least one inflection point in an off-axis region thereof; therefore, it is favorable for effectively reducing the incident angle of the off-axis on the image plane so as to improve the responding efficiency of the image sensor. 
     The sixth lens element can have an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. Therefore, it is favorable for the principal point being positioned away from the image plane so as to reduce the total track length of the image capturing lens assembly. In addition, the image-side surface of the sixth lens element has at least one inflection point in an off-axis region thereof, so that it is favorable for correcting the image distortion in a peripheral region thereof and improving the relative illumination. 
     When a focal length of the image capturing lens assembly is f, and a curvature radius of the image-side surface of the sixth lens element is R12, the following condition is satisfied: 0.25&lt;f/R12&lt;1.25. Therefore, it is favorable for reducing the back focal length of the image capturing lens assembly. 
     When a focal length of the first lens element is f1, and a curvature radius of the object-side surface of the second lens element is R3, the following condition is satisfied: |f1/R3|&lt;1.4. Therefore, it is favorable for improving the illumination. 
     When a focal length of the second lens element is f2, and a focal length of the third lens element is f3, the following condition is satisfied: |f2/f3|&lt;2.0. Therefore, it is favorable for balancing the refractive powers of the second and the third lens elements so as to correct the aberration. 
     When a maximal field of view of the image capturing lens assembly is FOV, the following condition is satisfied: 120 deg.≤FOV&lt;200 deg.. Therefore, the image capturing lens assembly can have larger field of view so as to obtain more of the image scene. 
     When the focal length of the first lens element is f1, the focal length of the second lens element is f2, and the focal length of the third lens element is f3, the following condition is satisfied: |f1/f2|+|f1/f3|&lt;1.0. Therefore, it is favorable for balancing the refractive powers of the image capturing lens assembly. 
     When an axial distance between the image-side surface of the sixth lens element and an image plane is BL, and the focal length of the image capturing lens assembly is f, the following condition is satisfied: BL/f&lt;1.0. Therefore, it is favorable for maintaining a proper back focal length. 
     When a curvature radius of the object-side surface of the sixth lens element is R11, and the curvature radius of the image-side surface of the sixth lens element is R12, the following condition is satisfied: −0.40&lt;(R11−R12)/(R11+R12)&lt;0.40. Therefore, it is favorable for effectively correcting the astigmatism. 
     According to the image capturing lens assembly of the present disclosure, the lens elements thereof can be made of glass or plastic material. When the lens elements are made of glass material, the distribution of the refractive power of the image capturing lens assembly may be more flexible to design. When the lens elements are made of plastic material, the manufacturing cost can be effectively reduced. Furthermore, surfaces of each lens element can be arranged to be aspheric, since the aspheric surface of the lens element is easy to form a shape other than spherical surface so as to have more controllable variables for eliminating the aberration thereof, and to further decrease the required number of the lens elements. Therefore, the total track length of the image capturing lens assembly can also be reduced. 
     According to the image capturing lens assembly of the present disclosure, each of an object-side surface and an image-side surface has a paraxial region and an off-axis region. The paraxial region refers to the region of the surface where light rays travel close to the optical axis, and the off-axis region refers to the region of the surface where light rays travel away from the optical axis. Particularly, when the lens element has a convex surface, it indicates that the surface is convex in the paraxial region thereof; when the lens element has a concave surface, it indicates that the surface is concave in the paraxial region thereof. 
     According to the image capturing lens assembly of the present disclosure, the image capturing lens assembly can include at least one stop, such as an aperture stop, a glare stop or a field stop. Said glare stop or said field stop is for eliminating the stray light and thereby improving the image resolution thereof. 
     According to the image capturing lens assembly of the present disclosure, an aperture stop is configured as a middle stop. The middle stop disposed between the first lens element and the image plane is favorable for enlarging the field of view of the image capturing lens assembly and thereby provides a wider field of view for the same. 
     According to the present disclosure, an image capturing device is provided. The image capturing device includes the image capturing lens assembly according to the aforementioned image capturing lens assembly of the present disclosure, and an image sensor, wherein the image sensor is disposed on or near an image plane of the aforementioned image capturing lens assembly. In some embodiments, the image capturing device can further include a barrel member, a holding member or a combination thereof. 
     In  FIG.  15   , an image capturing device  10  may be installed in but not limited to a vehicle photographing terminal. In some embodiments, the vehicle photographing terminal can further include, but not limited to, display, a control unit, a random access memory unit (RAM), a read only memory unit (ROM) or a combination thereof.
