     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a camera unit and an electronic device, more particularly to a camera unit having a wide-angle image capturing module, a standard image capturing module and a telephoto image capturing module and an electronic device having the camera unit. 
     2. Description of Related Art 
     In recent years, the advanced manufacturers not only improve the imaging resolution of miniaturized camera units installed on smart devices but also reduce a total track length of a lens assembly in the miniaturized camera unit in order to install the miniaturized camera units into the thinner smart devices. Therefore, the miniaturized camera unit has played a more prominent role on the smart devices and has more functions for the camera unit when the imaging resolution is improved. The functions include imaging technique of post-focusing adjustment, bokeh effect and automated post image processing. However, the miniaturized camera unit still lacks of the ability of optical zoom. 
     A conventional camera unit adopts an electro-mechanical part for zoom for performing the optical zoom. However, the electro-mechanical part for zoom consumes more power and needs longer space to accommodate a stabilization unit for avoiding the image distortion caused by shaking Therefore, the size of the camera unit is increased due to the adoption of the electro-mechanical part for zoom so that it is unfavorable for equipping the camera unit on the compact electronic device. 
     Some manufacturers develop a compact electronic device including a camera unit with two image capturing modules in order to satisfy the requirement of the ability of optical zoom and compact size simultaneously. For example, the camera unit can include a telephoto image capturing module and a wide-angle image capturing module. Nevertheless, compared with the camera unit including the electro-mechanical part for zoom, the camera unit including two image capturing modules is unfavorable for improving image resolution, having sufficient field of view and large zoom magnification.

     The standard image capturing module includes a standard lens assembly and a standard image sensor. The standard lens assembly includes, in order from an object side to an image side thereof, a first lens element thereof closest to the object-side and a last lens element thereof closest to the image-side. The first lens element and the last lens element of the standard lens assembly both have refractive power. In detail, the first lens element of the standard lens assembly is the closest lens element to the object side thereof among all lens elements of the standard lens assembly with refractive power, and the last lens element of the standard lens assembly is the closest lens element to the image side thereof among all lens elements of the standard lens assembly with refractive power (i.e., all lens elements of the standard lens assembly at least includes the first lens element and the last lens element of the standard lens assembly).

The standard image sensor is disposed on the image side of the standard lens assembly. There are at least three and fewer than seven lens elements with refractive power in the standard lens assembly. Preferably, there are at least four and fewer than six lens elements with refractive power in the standard lens assembly. 
     The telephoto image capturing module includes a telephoto lens assembly and a telephoto image sensor. The telephoto lens assembly includes, in order from an object side to an image side thereof, a first lens element thereof closest to the object-side and a last lens element thereof closest to the image-side. The first lens element and the last lens element of the telephoto lens assembly both have refractive power. In detail, the first lens element of the telephoto lens assembly is the closest lens element to the object side thereof among all lens elements of the telephoto lens assembly with refractive power, and the last lens element of the telephoto lens assembly is the closest lens element to the image side thereof among all lens elements of the telephoto lens assembly with refractive power (i.e., all lens elements of the standard lens assembly at least includes the first lens element and the last lens element of the telephoto lens assembly). Each of the lens elements of the telephoto lens assembly with refractive power has an object-side surface and an image-side surface. The telephoto image sensor is disposed on the image side of the telephoto lens assembly. There are at least three and fewer than seven lens elements with refractive power in the telephoto lens assembly. Preferably, there are at least four and fewer than six lens elements with refractive power in the telephoto lens assembly. 
     According to the camera unit of the present disclosure, all lens elements of the wide-angle lens assembly with refractive power are stationary relative to one another in a paraxial region thereof. All lens elements of the standard lens assembly with refractive power are stationary relative to one another in a paraxial region thereof. All lens elements of the telephoto lens assembly with refractive power are stationary relative to one another in a paraxial region thereof. For example, in some embodiments, an air gap in a paraxial region is located between every two of all lens elements that are adjacent to each other in the wide-angle lens assembly, the standard lens assembly and the telephoto lens assembly, and the air gaps are constant. Therefore, the wide-angle lens assembly, the standard lens assembly and the telephoto lens assembly are all single focus lens assemblies so that it is unnecessary to dispose additional add-on components such as electro-mechanical part for zoom or optical image stabilization unit, thereby it is favorable for keeping the camera unit compact. 
     When a maximal field of view of the wide-angle lens assembly FOV(W), a maximal field of view of the standard lens assembly FOV(M), a maximal field of view of the telephoto lens assembly FOV(T), the following condition is satisfied: FOV(T)&lt;FOV(M)&lt;FOV(W). Therefore, the wide-angle lens assembly, the standard lens assembly and the telephoto lens assembly with different field of views are favorable for capturing a plurality of images having various magnifications so as to satisfy the requirement of the ability of optical zoom. 
     When the maximal field of view of the wide-angle lens assembly FOV(W), the maximal field of view of the standard lens assembly FOV(M), the maximal field of view of the telephoto lens assembly FOV(T), the following conditions are satisfied: 15 degrees (deg.)&lt;FOV(T)&lt;50 deg.; 45 deg.&lt;FOV(M)&lt;100 deg.; and 70 deg.&lt;FOV(W)&lt;150 deg. Therefore, it is favorable for providing high zoom ratios and large zoom range so as to improve the ability of optical zoom. Preferably, the following conditions are satisfied: 30 deg.&lt;FOV(T)&lt;45 deg.; 70 deg.&lt;FOV(M)&lt;95 deg.; and 110 deg.&lt;FOV(W)&lt;140 deg. More preferably, the following conditions are satisfied: 20 deg.&lt;FOV(T)&lt;40 deg.; 45 deg.&lt;FOV(M)&lt;70 deg.; and 75 deg.&lt;FOV(W)&lt;100 deg. 
     When an axial distance between the object-side surface of the first lens element of the wide-angle lens assembly and the wide-angle image sensor is TL(W), an axial distance between the object-side surface of the first lens element of the standard lens assembly and the standard image sensor is TL(M), an axial distance between the object-side surface of the first lens element of the telephoto lens assembly and the telephoto image sensor is TL(T), the following conditions can be satisfied: TL(W)&lt;10 millimeters (mm); TL(M)&lt;10 mm; and TL(T)&lt;10 mm. Therefore, it is favorable for keeping the camera unit compact so as to be equipped in a compact electronic device. Preferably, the following conditions can be satisfied: TL(W)&lt;8 mm; TL(M)&lt;8 mm; and TL(T)&lt;8 mm. 
     When an axial distance between the image-side surface of the last lens element of the wide-angle lens assembly and the wide-angle image sensor is BL(W), an axial distance between the image-side surface of the last lens element of the standard lens assembly and the standard image sensor is BL(M), an axial distance between the image-side surface of the last lens element of the telephoto lens assembly and the telephoto image sensor is BL(T), the following conditions can be satisfied: BL(W)&lt;2 mm; BL(M)&lt;2 mm; and BL(T)&lt;2 mm. Therefore, it is favorable for keeping the camera unit compact so as to be equipped in the compact electronic device. Preferably, the following conditions can be satisfied: BL(W)&lt;1.5 mm; BL(M)&lt;1.5 mm; and BL(T)&lt;1.5 mm. 
     When a diagonal length of an effective photosensitive area of the wide-angle image sensor (i.e., two times a maximum image height of the wide-angle lens assembly) is D(W), a diagonal length of an effective photosensitive area of the standard image sensor (two times a maximum image height of the standard lens assembly) is D(M), a diagonal length of an effective photosensitive area of the telephoto image sensor (two times a maximum image height of the telephoto lens assembly) is D(T), the following conditions can be satisfied: D(T)&lt;D(M) and D(W)&lt;D(M). Therefore, it is favorable for improving the image quality of the image captured by the camera unit. 
     When the maximal field of view of the wide-angle lens assembly FOV(W), the maximal field of view of the telephoto lens assembly FOV(T), the following condition can be satisfied: 2.0&lt;FOV(W)/FOV(T)&lt;5.0. Therefore, it is favorable for properly arranging the field of views of the wide-angle lens assembly and the telephoto lens assembly so as to provide wide-angle characteristic when the camera unit photographs a moving object. 
     When an f-number of the wide-angle lens assembly is Fno(W), an f-number of the standard lens assembly is Fno(M), an f-number of the telephoto lens assembly is Fno(T), the following conditions can be satisfied: 1.5&lt;Fno(W)&lt;3.0; 1.5&lt;Fno(M)&lt;3.0; and 1.5&lt;Fno(T)&lt;3.0. Therefore, the wide-angle lens assembly, the standard lens assembly and the telephoto lens assembly are all favorable for obtaining a large aperture for receiving sufficient incoming light, thereby increasing the image quality while the camera unit is in a low light condition with a shutter at a high speed. 
     When the f-number of the standard lens assembly is Fno(M), the following condition can be satisfied: 1.5&lt;Fno(M)&lt;2.4. Therefore, it is favorable for providing sufficient incoming light while the camera unit photographs the imaged object by the standard image capturing module. 
     According to the camera unit of the present disclosure, at least one of the image-side surfaces of the last lens elements of the wide-angle lens assembly, the standard lens assembly, and the telephoto lens assembly can have a wave-like shape. For example, when the image-side surface of the last lens element is concave in a paraxial region, the image-side surface of the last lens element can have at least one convex shape in an off-axis region. When the image-side surface of the last lens element is convex in a paraxial region, the image-side surface of the last lens element can have at least one concave shape in an off-axis region. 
     According to the camera unit of the present disclosure, each of the wide-angle image sensor, the standard image sensor and the telephoto image sensor has a pixel size being smaller than 2.0 micrometers (μm). Therefore, it is favorable for enhancing the image resolution and the image quality of the image captured by the camera unit. 
     When a focal length of the wide-angle lens assembly is f(W), a focal length of the telephoto lens assembly is f(T), the following condition can be satisfied: 2.0&lt;f(T)/f(W)&lt;5.0. Therefore, it is favorable for obtaining a balance between the telecentric and wide-angle characteristics. 
     When the axial distance between the object-side surface of the first lens element of the wide-angle lens assembly and the wide-angle image sensor is TL(W), the axial distance between the object-side surface of the first lens element of the telephoto lens assembly and the telephoto image sensor is TL(T), the following condition can be satisfied: TL(W)&lt;TL(T). Therefore, it is favorable for obtaining a balance between the telecentric and wide-angle characteristics. 
     When the maximal field of view of the wide-angle lens assembly FOV(W), the maximal field of view of the standard lens assembly FOV(M), the maximal field of view of the telephoto lens assembly FOV(T), the following conditions are satisfied: 15 degrees&lt;FOV(M)−FOV(T)&lt;45 degrees, and 20 degrees&lt;FOV(W)−FOV(M)&lt;60 degrees. Therefore, it is favorable for allowing the field of view of the standard lens assembly to properly cover the difference between that of the wide-angle lens assembly and that of the telephoto lens assembly; thereby the camera unit is for capturing different kinds of imaged objects all with good image qualities. 
     According to the camera unit of the present disclosure, each lens assembly can have an aperture stop configured as a front stop or a middle stop. A front stop disposed between an imaged object and a lens element being the closest one to the imaged object can provide a longer distance between an exit pupil of the lens assembly and the image surface, and thereby improves the image-sensing efficiency of an image sensor (for example, CCD or CMOS). A middle stop disposed between the lens element being the closest one to the imaged object and the image surface is favorable for enlarging the field of view of the camera unit and thereby provides a wider field of view for the same. 
     According to the camera unit of the present disclosure, all 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 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 lens assembly can also be reduced. 
     According to the camera unit 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 away from the paraxial region. 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. Moreover, when a region of refractive power or focus of a lens element is not defined, it indicates that the region of refractive power or focus of the lens element is in the paraxial region thereof. 
     According to the camera unit of the present disclosure, an image surface of the lens assembly, based on the corresponding image sensor, can be flat or curved, especially a curved surface being concave facing towards the object side of the lens assembly. 
     According to the camera unit of the present disclosure, each 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 set for eliminating the stray light and thereby improving the image quality thereof. 
     According to the present disclosure, an image capturing unit is provided. The image capturing unit includes the camera unit according to the aforementioned camera unit of the present disclosure, and an image sensor, wherein the image sensor is disposed on the image side of the aforementioned camera unit, that is, the image sensor can be disposed on or near an image surface of the aforementioned camera unit. In some embodiments, the image capturing unit can further include a barrel member, a holding member or a combination thereof. 
       FIG. 3  shows a wide-angle image capturing module, a standard image capturing module and a telephoto image capturing module having different field of views according to one embodiment of the present disclosure.  FIG. 4  shows the images captured by the wide-angle image capturing module, the standard image capturing module and the telephoto image capturing module in  FIG. 3  according to the embodiment of the present disclosure. As shown in  FIG. 3 , a camera unit  10  includes a wide-angle image capturing module W, a standard image capturing module M and a telephoto image capturing module T. Each of the wide-angle image capturing module W, the standard image capturing module M and the telephoto image capturing module T can further include an independent barrel, a holding member, an auto-focusing lens actuator, an optical image stabilization unit or a combination thereof. 
     As shown in  FIG. 4 , the wide-angle image capturing module W has a field of view being larger than that of the standard image capturing module M and that of the telephoto image capturing module T. The standard image capturing module M has a field of view being smaller than that of the wide-angle image capturing module W but larger than that of the telephoto image capturing module T. The telephoto image capturing module T has a field of view being smaller than that of the standard image capturing module M and that of the telephoto image capturing module T. When the camera unit  10  photographs an imaged object (for example, a plurality of moving cars in  FIG. 4 ), the wide-angle image capturing module W takes a long shot (also referred to as a full shot or a wide shot) to capture an image I W  with a wider view of the imaged object, the standard image capturing module M takes a medium shot to capture an image I M  with a smaller view of the imaged object than the image I W  (for example, one of the moving cars in  FIG. 4 ), and the telephoto image capturing module T takes a close-up shot to capture an image I T  with the smallest view of the imaged object (for example, a front portion of the one of the moving cars in  FIG. 4 ). Therefore, it is favorable for capturing the images with the foregoing image capturing modules W, M and T having different field of views so as to satisfy the requirement of the ability of optical zoom. 
     In  FIG. 5A ,  FIG. 5B  and  FIG. 5C , the camera unit  10  may be installed in, but not limited to, an electronic device, including a smart phone, a tablet personal computer or a wearable device. The three figures of different kinds of electronic device are only exemplary for showing the camera unit  10  of present disclosure installing in an electronic device and is not limited thereto. In some embodiments, the electronic device can further include, but not limited to, a display unit, a control unit, a storage unit, a random access memory unit (RAM), a read only memory unit (ROM) or a combination thereof. Furthermore, the wide-angle image capturing module W, the standard image capturing module M and the telephoto image capturing module T of the camera unit  10  can be disposed in a linear or triangular arrangement. As shown in  5 A,  FIG. 5B  and  FIG. 5C , the wide-angle image capturing module W, the standard image capturing module M and the telephoto image capturing module T can be arranged in a vertical line ( FIG. 5A ), a horizontal line ( FIG. 5B ) or a shape of a triangle ( FIG. 5C ). According to the present disclosure, the arrangement and the positions of the wide-angle image capturing module W, the standard image capturing module M and the telephoto image capturing module T can all be adjusted based on actual requirements. 
     According to the camera unit of the present disclosure, the camera unit can be optionally applied to an optical system for movably focusing. Furthermore, the camera unit is featured with good capability in the correction of aberration and high image quality, and can be applied to 3D (three-dimensional) image capturing applications. For example, a plurality of raw images are captured from at least two of the wide-angle image capturing module, the standard image capturing module and the telephoto image capturing module of the camera unit, and a final photographed image is produced by post-processing of the raw images (such as 3D image post processing). The camera unit can be applied to various devices, in products such as digital cameras, mobile devices, digital tablets, wearable devices, smart televisions, wireless monitoring devices, motion sensing input devices, driving recorders, rear view cameras and other electronic imaging devices.
