Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

FIG. 1 is a schematic structural diagram of a lens module provided by an embodiment of the present disclosure, and FIG. 2 is a structural schematic diagram of a folding lens in a lens module according to an exemplary embodiment.

As shown in FIG. 1 , the camera module includes: a folding lens 1 , and the folding lens 1 is used to obtain a first captured image. The first non-folding lens 2, the focal length of the first non-folding lens 2 is smaller than the focal length of the folding lens 1, and the first non-folding lens 2 is used to obtain the second photographed image. Wherein, the distance between the folding lens 1 and the first non-folding lens 2 is smaller than the first preset distance, so that the second captured image includes at least the bokeh area of the first captured image.

In one embodiment, the folding lens 1 has a structure as shown in FIG. 2 , including a first lens 11 , a reflection element 12 , a correction lens 13 , and a reflection element 14 arranged along the light incident direction. Also, the reflection element 14 has a central through hole. The incident light passes through the first lens 11 and passes through the reflection element 14 for the first reflection; the light after the first reflection is irradiated on the reflection element 12 for the second reflection; The center hole of the reflection element 14 shoots out the foldback lens 1 and presents an image on the image sensor. The emitting element 14 may be a concave mirror with a central through hole. The fold-back lens 1 forms a fold-back optical path through the reflective elements 12 and 14, so that a longer focal length can be achieved without increasing the total length of the lens.

However, since the reflective element 12 in the fold-back lens 1 blocks part of the incident light, a ring-shaped light spot will appear in the bokeh area of the first captured image obtained by the fold-back lens 1 . In order to prevent the final display image from having a ring-shaped light spot, the camera module provided in this embodiment is provided with a first non-folding lens 2 whose distance from the folding lens 1 is smaller than the first preset distance, and the first captured image is obtained at the folding lens 1 At the same time, the first non-folding lens 2 acquires the second captured image. Since the distance between the two groups of lenses is smaller than the first preset distance, the field of view of the first non-folding lens 2 (FOV2 in FIG. 1 ) can cover the field of view of the folding lens 1 (FOV1 in FIG. 1 ), and the first The second photographed image obtained by a non-return lens 2 includes the bokeh area of the first photographed image obtained by the return lens 1 . Accordingly, the bokeh area of the first captured image can be corrected by using the second captured image to remove the annular light spot, and the display image finally presented on the display can be synthesized.

Accordingly, in the camera module provided in this embodiment, the optical zoom function is realized by the cooperation of the folding lens 1 and the first non-folding lens 2 having different focal lengths. When shooting close-up shots, the first non-return lens 2 is used for shooting. When shooting long-range shots or zooming in, use the foldback lens 1 as the main lens, the first non-foldback lens 2 as the auxiliary lens, and the foldback lens 1 and the first non-foldback lens 2 are used to view the scene at the same time to ensure the clarity of the displayed image. The use of the fold-back lens can further improve the optical zoom magnification of the camera module, improve the clarity of the image during high magnification magnification shooting, and optimize the user experience. Moreover, the use of the folding lens is no longer limited to the method in the related art, which can only be increased by increasing the length of the lens to improve the focal length of the camera module. In this case, when the camera module is applied to electronic devices such as mobile phones, the design requirements for hardware such as the casing of the electronic device are reduced, and in particular, the thickness of the casing can be further reduced.

In one embodiment, the zoom factor of the camera module is the ratio of the focal lengths of the folding lens 1 and the first non-folding lens 2 . In this embodiment, the zoom magnification of the camera module is not specifically limited, such as 2 times, 3 times, 4 times, 5 times, and the like. Regarding the lens type of the first non-folding lens 2, optionally, the first non-folding lens 2 is a telephoto lens, a standard focal length lens, or a wide-angle lens. Among them, it is preferable that the first non-folding lens 2 is a telephoto lens. In this case, the focal length of the folding lens 1 and the focal length of the folding lens 2 are not much different, so the second captured image is useful for correcting the bokeh area of the first captured image. The reference is higher, and the image quality of the displayed image corrected with reference to the second captured image is guaranteed to avoid distortion.

In one embodiment, optionally, the pixels of the folding lens 1 are larger than the pixels of the first non-folding lens 2 . The digital zoom is used when taking magnified shots that are beyond the clear shooting range of the foldback lens 1. In this case, the pixels of the fold-back lens 1 are higher than those of the first non-fold-back lens 2, which helps to optimize the performance of the digital zoom and improve the clarity of the enlarged image. Optionally, the pixels of the folding lens 1 and the first non-folding lens 2 are the same. In this case, the cost of the equipment is lower and the overall installation is cost-effective. Especially when the camera device has a zoom magnification of more than 3 times, the zoom magnification can already meet the daily needs of consumers, and there is rarely a need for higher magnification magnification shooting, so there is no need to configure a high-pixel folding lens 1 .

In one embodiment, the total length of the lens of the folding lens 1 is less than or equal to the total length of the lens of the first non-folding lens 2 . In this case, when the camera module provided in this embodiment is applied to an electronic device, it is not necessary to increase the thickness of the electronic device. In particular, when the first non-folding lens 2 is a wide-angle lens, a standard focal length lens, or a telephoto lens with a relatively short focal length, it can be applied to an electronic device with a thin structure.

In one embodiment, the first non-return lens 2 can be selectively activated. When the first non-folding lens 2 is not activated, the bokeh area of the first captured image obtained by the folding lens 1 has an annular light spot. Since the annular light spot formed by the fold-back lens 1 can enrich the visual effect of the image, the first non-fold-back lens 2 can be selectively activated to retain this characteristic of the fold-back lens 1, and users can obtain unique visual effects without post-processing. image.

In one embodiment, as shown in FIG. 1 , the camera module further includes a second non-folding lens 3 . The focal length of the second non-folding lens 3 is smaller than the focal length of the first non-folding lens 2, and the second non-folding lens 3 is used to obtain the third photographed image. The distance between the first non-folding lens 2 and the second non-folding lens 3 is smaller than the second preset distance, so that the frame of the third captured image includes the frame of the second captured image.

By adding a second non-folding lens 3 with a smaller focal length, the zoom ratio of the camera module is improved. And by switching to three sets of lenses, the camera module can achieve three focal lengths to be suitable for different shooting scenarios. For example, the second non-return lens 3 is used for close-up photography, the turn-back lens 1 is used for long-range photography, and the first non-return lens 2 is used to capture the range between the close-up and the long-range.

In this embodiment, the distance between the first non-folding lens 2 and the second non-folding lens 3 is smaller than the second preset distance, so that the field of view (FOV3 in FIG. 1 ) of the second non-folding lens 3 can cover the first The field of view of a non-return lens 2 (FOV2 in FIG. 1 ), and the third captured image captured by the second non-return lens 3 includes the second captured image captured by the first non-return lens 2 . In this case, the second captured image obtained by the first non-return lens 2 and the third captured image obtained by the second non-return lens 3 can be synthesized and presented on the display as a display image. The display image synthesized by the second captured image and the third captured image has the characteristics of a large screen range and rich details. Specifically, since the field of view (FOV3) of the second non-folding lens 3 is large, the displayed image has a large screen range. Since the focal length of the first non-folding lens 2 is longer, the details of the displayed image are clearer. In addition, the first non-folding lens 2 and the second non-folding lens 3 can also be used to perform magnification shooting, and the magnification at this time is smaller than the magnification that can be achieved by the folding lens 1 .

In one embodiment, there is no specific limitation on the arrangement of the three groups of lenses, as long as the distance between the folding lens 1 and the first non-folding lens 2 is smaller than the first preset distance, the first non-folding lens 2 and the first non-folding lens 2 are smaller than the first preset distance. The distance between the two non-folding lenses 3 is smaller than the second preset distance. For example, FIG. 3 is a schematic diagram of the arrangement of three groups of lenses in a camera module according to an exemplary embodiment, and FIG. 4 is a schematic diagram of an arrangement of three groups of lenses in a camera module according to another exemplary embodiment. As shown in Figure 3, the three groups of lenses can be arranged in a "one" character. At this time, the three groups of lenses can be arranged along the length of the electronic device, or along the width of the electronic device; as shown in Figure 4, the three groups of lenses ” font arrangement.

In this embodiment, since the imaging directions of the fold-back lens 1, the first non-fold-back lens 2 and the second non-fold-back lens 3 are not changed, the camera module can use the actuators and other accessories provided in the related art to avoid increasing equipment cost.

And optionally, the first non-folding lens 2 is a telephoto lens, and the second non-folding lens 3 is a wide-angle lens. Accordingly, the camera module can achieve a large field of view and a long focal length to obtain images with different effects. At the same time, the overall camera module has low requirements on the total length of the lens, and is suitable for electronic equipment with a thin structure.

In one embodiment, the camera module further includes: an optical anti-shake component adapted to the folding lens and the non-folding lens, respectively. The optical image stabilization device can reduce the problem of poor shooting effect caused by shaking, and further improve the display image quality.

FIG. 5 is a schematic structural diagram of an electronic device according to an exemplary embodiment. As shown in FIG. 5 , the electronic device includes: the camera module provided in the above-mentioned embodiment, the camera module is used to obtain the first captured image and the second captured image. 2 captured images; and, a processing module (not shown in the figure), the processing module is configured to correct the bokeh area of the first captured image according to the second captured image.

The electronic device has the camera module provided in the above-mentioned embodiment, so it has a longer focal length and an optical zoom function. And because the camera module does not have high requirements on the total length of the lens, the electronic device can achieve a smaller thickness, which helps to reduce the size of the device and optimize the user experience.

The types of electronic devices are not specifically limited, and may be mobile phones, computers, notebook computers, tablet devices, personal digital assistants, and the like.
