detailed description

Embodiments of the present invention are described in detail below, the embodiments of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, but should not be construed as limiting the present utility model.

Referring to FIG. 1 , an imaging device 10 according to an embodiment of the present invention includes a wide-angle camera 12 and a telephoto camera 14 . The field of view of the telephoto camera 14 is located in the field of view of the wide-angle camera 12, the telephoto camera 14 includes a telephoto lens 142, and the telephoto lens 142 includes at least one first lens 1422 arranged in sequence along the optical axis from the object side to the image side, Refractive element 1424 and at least one second optic 1426 . The refractive element 1424 is used to refract the optical axis from the first direction to the second direction.

Please refer to FIG. 2 , the imaging device 10 of the present invention can be applied to the electronic device 100 of the present invention, or the electronic device 100 of the present invention includes the imaging device 10 of the present invention.

In addition to the imaging device 10 , the electronic device 100 according to the embodiment of the present invention also includes a casing 20 , the imaging device 10 is disposed in the casing 20 , and the axial direction of the wide-angle camera 12 is substantially parallel to the thickness direction of the casing 20 .

The imaging device 10 and the electronic device 100 of the present utility model bend the optical axis of the telephoto lens 142. Since the wide-angle camera 12 and the first direction are generally arranged along the height of the imaging device 10, the optical axis of the bending telephoto lens 142 can be reduced. The height of the imaging device 10. In this way, when the imaging device 10 is applied to the electronic device 100 and disposed inside the housing 20 and the height direction of the imaging device 10 is substantially parallel to the thickness direction of the housing 20 , it is beneficial to thinning the electronic device 100 .

In some embodiments, the height direction of the imaging device 10 is substantially parallel to the axial direction of the wide-angle camera 12, that is, the height direction of the imaging device 10 is substantially parallel to the thickness direction of the housing 20 in the Z direction in FIG. 1 of the embodiment of the present invention. parallel. The height of the imaging device 10 is slightly smaller than the thickness of the casing 20 .

In this way, the thickness of the electronic device 100 can be fully utilized and the imaging device 10 can be accommodated in the housing 20 , preventing the imaging device 10 from being intruded or disturbed by the outside, and ensuring that the imaging device 10 can work normally.

In some embodiments, the field angle of the wide-angle camera 12 is 75-85 degrees, and the field angle of the telephoto camera 14 is 20-60 degrees.

It can be understood that the larger the angle of view of the wide-angle camera 12 is more conducive to reducing the height of the imaging device 10, however, since the wide-angle camera 12 is generally used as the main camera for shooting, an excessively large angle of view may cause image quality to deteriorate. Therefore, the wide-angle camera When the field of view angle of 12 is set between 75-85 degrees, it is beneficial to control the height of the imaging device 10 and can ensure the imaging effect of the wide-angle camera 12 . In the embodiment of the present utility model, the field angle of the wide-angle camera 12 is about 80 degrees.

It can be understood that the smaller the field of view angle of the telephoto camera 14 is, the more it is beneficial to increase the zoom ratio of the imaging device 10, but this will increase the height of the telephoto camera 14, and too low is not conducive to increasing the zoom ratio of the imaging device 10. The field of view angle of the telephoto camera 14 can be set at 20-60 degrees, which is beneficial to increase the zoom ratio of the imaging device 10 and to control the size of the imaging device 10 . In the embodiment of the present utility model, the field angle of the telephoto camera 14 is about 40 degrees.

In some implementations, the height of the telephoto camera 14 is less than or equal to the height of the wide-angle camera 12 .

It can be understood that the purpose of bending the optical axis of the telephoto lens 142 is to reduce the height of the telephoto camera 14. In order to make the electronic device 100 thinner, the height of the bent telephoto camera 14 is slightly lower than the height of the wide-angle camera 12. Or approximately the same.

In some embodiments, the field of view of the telephoto camera 14 is located within the field of view of the wide-angle camera 12 .

In this way, when the wide-angle camera 12 is working, the user zooms the cached wide-angle image of the wide-angle camera 12, and switches to the telephoto camera 14 when zooming reaches the field of view angle of the telephoto camera 14. Since the field of view of the telephoto camera 14 is located at In the field of view of the wide-angle camera 12, the scene that the user originally wanted to shoot can be imaged without readjusting the position of the telephoto camera 14.

In some embodiments, the height of the telephoto camera 14 is greater than that of the wide-angle camera 12 .

In this way, it is necessary to use the telephoto camera 14 of the embodiment of the present utility model, and utilize the advantages of the telephoto camera 14 of the embodiment of the present utility model, so that the telephoto camera 14 can work normally without affecting the thinning of the electronic device 100 .

In some implementations, the optical axis of the wide-angle camera 12 is parallel to the first direction. In reality, due to technological reasons or factors such as camera loosening, the optical axis of the wide-angle camera 12 may not be parallel to the first direction, but there is a certain angle, such as the optical axis of the wide-angle camera 12 and the first direction. An included angle of 2 degrees, without any limitation here.

In this way, the optical axis of the wide-angle camera 12 is substantially parallel to the first direction of the optical axis of the telephoto camera 14, so that the field of view of the telephoto camera 14 is located in the field of view of the wide-angle camera 12. When the electronic device 100 adjusts the angle too much, it can focus and shoot the scene shot by the wide-angle camera 12 .

Please refer to FIG. 1 , FIG. 3 and FIG. 4 together. In some implementations, the telephoto camera 14 and the wide-angle camera 12 are arranged side by side, and the second direction extends away from the wide-angle camera 12 . In the figure of the embodiment of the present invention, the X direction refers to the direction of the width of the electronic device 100 , the Y direction refers to the direction of the length of the electronic device 100 , and the Z direction refers to the direction of the thickness of the electronic device 100 .

In this way, the overlap between the field of view of the telephoto camera 14 and the field of view of the wide-angle camera 12 can be increased, that is, the proportion of the field of view of the telephoto camera 14 in the field of view of the wide-angle camera 12 can be increased. Since the wide-angle camera 12 and the telephoto camera 14 have the same shooting object when zooming, the adjacent arrangement of the telephoto camera 14 and the wide-angle camera 12 is conducive to improving the imaging capability of the imaging device 10 and avoiding the user from moving the electronic device 100. No action is necessary.

In some implementations, the direction away from the wide-angle camera 12 may be the X direction or the Y direction, that is to say, the second direction may be the direction where the length or width of the electronic device 100 is located.

In this way, the direction where the second lens 1426 is located is not the direction where the thickness of the electronic device 100 is located, so when the telephoto camera 14 is housed in the electronic device 100 , the thickness of the electronic device 100 will not be increased.

In some embodiments, the area of the refraction element 1424 transmitted to the X-Y plane may be slightly larger or nearly the same as the area of the first lens 1422 transmitted to the XY plane.

In this way, all the light collected from the first lens 1422 can be refracted to the second lens 1426 through the refraction element 1424, so that the incident light from the outside can be utilized to the greatest extent, the loss of incident light can be avoided, and the imaging capability of the imaging device 10 can be improved. .

In some embodiments, the second direction is perpendicular to the first direction. In reality, due to technical reasons or factors such as the looseness of the refractive element 1424, the second direction may not be perpendicular to the first direction, but there is a certain angle deviation, for example, the angle between the second direction and the first direction is 88 degrees, there is no limit here.

In this way, the second direction can be made in the direction where the length or width of the electronic device 100 is located, so that by taking advantage of the space advantage of the electronic device 100 in the non-thickness direction, the telephoto camera 14 can ensure a long focal length without affecting the electronic device 100. Thin and light.

In the embodiment of the present utility model, the telephoto lens 142 includes a first lens 1422 , a refractive element 1424 and a second lens 1426 . Utilizing the first lens 1422 to condense the incident light can increase the incidence rate of the incident light, reduce the loss of light caused by light scattering or diffusion, and help improve the brightness of the light received by the telephoto camera 14, and improve Telephoto camera 14 work efficiency. In addition, the first lens 1422 is arranged at the light entrance position of the telephoto camera 14, which can prevent dust or other pollution sources from entering the interior of the telephoto camera 14, causing the telephoto camera 14 to fail to work normally.

In some embodiments, the number of the first lens 1422 and the number of the second lens 1426 may be one or more, and there is no limitation here.

In some embodiments, the refractive element 1424 includes a mirror or a reflective prism.

In this way, using the refraction effect of the refraction element 1424, the direction of the incident light can be changed, so that the second lens 1426 can be arranged along the second direction, so that the height of the telephoto camera 14 can be greatly increased without affecting the performance of the electronic device 100. Thin and light.

In some embodiments, the electronic device 100 includes a mobile phone or a tablet computer, without any limitation here. In the embodiment of the present invention, the electronic device 100 is a mobile phone.

In some embodiments, the imaging device 10 includes dual front cameras or dual rear cameras.
