[0028] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0029] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides an electronic device 100. The electronic device 100 includes a first part 10, a second part 20, an auxiliary lens 30, a first display 51, and a second display 52.

[0030] The electronic device 100 can be any of various types of computer system devices that are mobile or portable and perform wireless communication. For example, the electronic device 100 can be a mobile phone, a portable gaming device, a laptop computer, a personal digital assistant (PDA), a portable Android device (PAD), a portable Internet device, a wearable device, a vehicle-mounted terminal, a navigator, a music player, and a data storage device, etc.

[0031] In this embodiment, the second part 20 is rotatably connected to the first part 10. The second part 20 rotates relative to the first part 10 between a first position and a second position. When the second part 20 is in the first position, the electronic device 100 is in an unfolded state, as Figure 1 shown; when the second part 20 is in the second position, the electronic device 100 is in a folded state, as Figure 2 shown.

[0032] In this way, the user can rotate the relative positions of the first part 10 and the second part 20 to make the electronic device 100 in an unfolded state, a folded state, or an intermediate state between the unfolded state and the folded state, so as to meet the application requirements of different scenarios.

[0033] For example, if the electronic device 100 is a flip phone, the user can rotate the second part 20 to the first position to make the electronic device 100 in a folded state, so as to facilitate storage. The user can rotate the second part 20 to the second position to make the electronic device 100 in an unfolded state, so as to input a number by pressing a key to make a call.

[0034] Another example is that if the electronic device 100 is a folding screen phone, the user can rotate the second part 20 to the first position to make the electronic device 100 in a folded state, so as to facilitate single-handed holding during a call. The user can rotate the second part 20 to the second position to make the electronic device 100 in an unfolded state to watch videos on a larger screen.

[0035] For convenience of description, hereinafter, the electronic device 100 is taken as an example of a folding screen phone for illustration.

[0036] Please refer to Figure 3 together. In this embodiment, the auxiliary lens 30 is located on the second part 20. When the second part 20 is in the second position, the auxiliary lens 30 is located on the optical axis 1221 of the imaging module 12 to assist the imaging module 12 in acquiring an image. In this way, it is avoided that the first part 10 has a large thickness due to the high lens of the imaging module 12, which is beneficial to the beauty of the appearance of the electronic device 100 and the convenience of carrying. It can also make the shooting effect of the electronic device 100 better when folded, which is beneficial to improving the image quality.

[0037] It can be understood that the auxiliary lens 30 being located on the optical axis 1221 of the imaging module 12 is equivalent to increasing the number of lenses for the imaging module 12 to image, which is beneficial to adjusting optical parameters such as the focal length, aberration, and distortion of the imaging module 12, so that the details of the acquired image are richer. Moreover, it can make the area where the light is projected on the image sensor larger, enabling more pixels to be sensitive to light, thereby improving the resolution of the image. In this way, the clarity and quality of the image can be improved.

[0038] InFigure 2 In the example, the electronic device 100 can be folded once, and the number of auxiliary lenses 30 is one. It can be understood that in other examples, the electronic device 100 can be folded multiple times, and the number of auxiliary lenses 30 is multiple.

[0039] It should be noted that the auxiliary lens 30 is inserted through the second part 20, and light can pass through the auxiliary lens 30 from one side of the second part 20 and exit from the other side.

[0040] The first part 10 is provided with an imaging module 12. Please refer to Figure 3 , the imaging module 12 includes a main lens 122, a first driving device 124, and an image sensor 126.

[0041] The main lens 122 includes, but is not limited to, a wide-angle lens, a telephoto lens, a fish-eye lens, and a macro lens. The specific form of the main lens 122 is not limited herein.

[0042] The main lens 122 is connected to the first driving device 124, and the first driving device 124 is used to drive the main lens 122 to move to achieve focusing. In this way, by driving the main lens 122 to move by the first driving device 124 to achieve focusing, the imaging module 12 can capture clear images, which is beneficial to improving the image quality.

[0043] Specifically, the first driving device 124 is used to drive the main lens 122 along the optical axis of the imaging module 12, that is, the optical axis 1221 of the main lens 122, to move to achieve focusing.

[0044] In this embodiment, the first driving device 124 includes a voice coil motor 1242 (Voice Coil Motor, VCM), and the main lens 122 is disposed in the voice coil motor 1242, as Figure 3 shown.

[0045] The voice coil motor 1242 is a device that converts electrical energy into mechanical energy and can achieve linear and limited swing angle movements. Using the voice coil motor 1242 as the first driving device 124 can ensure that the first driving device 124 can drive the main lens 122 to move to achieve focusing. Moreover, the voice coil motor 1242 is widely used and easy to obtain, which can reduce the cost of the electronic device 100.

[0046] In one example, the first driving device 124 is used to drive the main lens 122 to move to achieve phase detection autofocus (PDAF). Specifically, when the main lens 122 is at the current position, calculations can be performed based on the image obtained by the imaging module 12 to determine the target position, and the first driving device 124 is controlled to drive the main lens 122 to move to the target position.

[0047] In other words, the first driving device 124 is used to drive the main lens 122 to move to a target position, and the target position is determined according to the image acquired by the imaging module 12 when the main lens 122 is at the current position. In this way, focusing can be completed only by calculating once, the focusing speed is relatively fast, and the computational burden on the processor of the electronic device 100 can be reduced.

[0048] In another example, the first driving device 124 is used to drive the main lens 122 to move to achieve contrast focusing. Specifically, the first driving device 124 can be controlled to drive the main lens 122 to move along the optical axis, calculate the sharpness of the image acquired by the imaging module 12 when the main lens 122 is at each position, and use the position corresponding to the image with the maximum sharpness as the target position.

[0049] In other words, the first driving device 124 is used to drive the main lens 122 to move to a target position, and the target position is the position corresponding to the image with the maximum sharpness among the images acquired by the imaging module 12 when the main lens 122 is at each position. In this way, the focusing is more accurate, and accurate focusing can be achieved even in low-light environments, and the adaptability to the environment is strong.

[0050] The specific method of focusing is not limited herein.

[0051] In this embodiment, when the second part 20 is in the second position, the first driving device 124 is used to drive the main lens 122 to move so that the coaxiality of the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30 is less than a preset coaxiality threshold.

[0052] In this way, by driving the main lens 122 to move by the first driving device 124 to adjust the coaxiality of the main lens 122 and the auxiliary lens 30, it is possible to avoid image blurring caused by excessive coaxiality, which is beneficial to improving the quality of the image acquired by the imaging module 12.

[0053] It can be understood that the adjustment of the lens coaxiality is relatively delicate. When the second part 20 is in the second position, the auxiliary lens 30 is only roughly on the optical axis 1221 of the imaging module 12, and usually the coaxiality of the main lens 122 and the auxiliary lens 30 cannot be made less than the preset coaxiality threshold. Therefore, when the second part 20 is in the second position, it is necessary to finely adjust the position of the lens so that the coaxiality of the main lens 122 and the auxiliary lens 30 is less than the coaxiality threshold, thereby avoiding poor image quality caused by large coaxiality and being beneficial to improving the image quality.

[0054] Please note that the coaxiality here can represent the degree of non-coaxiality between the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30.

[0055] Please refer to Figure 4, in this embodiment, the coaxiality threshold includes a distance threshold. The first driving device 124 is used to drive the main lens 122 to move in a plane perpendicular to the optical axis of the main lens 122, so that the optical axis distance A is less than a preset distance threshold. The optical axis distance A is the distance between the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30.

[0056] Please note that the optical axis distance A here refers to the distance between the intersection point 310 of the optical axis 31 of the auxiliary lens 30 and the plane where the optical center 1220 of the main lens 122 is located, and the optical center 1220 of the main lens 122.

[0057] In this embodiment, the numerical range of the distance threshold is: 0.05 mm - 0.15 mm. For example, it is 0.05 mm, 0.09 mm, 0.1 mm, 0.13 mm, 0.15 mm. The specific value of the distance threshold is not limited here. In Figure 4 the example of

[0058] Specifically, the first driving device 124 may include a first driving member and a first transmission member. The first transmission member connects the first driving member and the main lens 122. The first driving member is used to drive the first transmission member to move, so as to drive the main lens 122 to move in a plane perpendicular to the optical axis 1221 of the main lens 122, thereby making the optical axis distance A less than a preset distance threshold.

[0059] Furthermore, the first transmission member may include a gear and a rack meshing with the gear. The gear is connected to the first driving member, and the rack is connected to the main lens 122. The first driving member is used to drive the gear to rotate, so as to drive the rack to move, thereby driving the main lens 122 to move in a plane perpendicular to the optical axis of the main lens 122.

[0060] In this way, by driving the main lens 122 to move in a plane perpendicular to the optical axis of the main lens 122, the adjustment of the optical axis distance A is realized, thereby adjusting the coaxiality between the main lens 122 and the auxiliary lens 30, and the image blurring caused by a large optical axis distance A can be avoided, thereby improving the image quality.

[0061] Please refer to Figure 5 , in this embodiment, the coaxiality threshold includes an angle threshold. The first driving device 124 is used to drive the main lens 122 to rotate, so that the optical axis angle α is less than a preset angle threshold. The optical axis angle α is the angle between the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30.

[0062] In this embodiment, the numerical range of the angle threshold is: 0.05° - 0.15°. For example, it is 0.05°, 0.09°, 0.1°, 0.13°, 0.15°. The specific value of the angle threshold is not limited here. In Figure 5In the example, after adjustment, the angle of the optical axis included angle α is 0°.

[0063] Specifically, the first driving device 124 includes a second driving member and a first connecting member. The first connecting member connects the second driving member and the main lens 122. The second driving member is used to drive the first connecting member to rotate, so as to drive the main lens 122 to rotate, so that the optical axis included angle α is less than a preset angle threshold.

[0064] Further, please refer to Figure 6 , the first connecting member includes a first connecting arm 1245 and a second connecting arm 1246 both connected to the main lens 122. The second driving member is used to drive the first connecting arm 1245 to rotate, so as to drive the main lens 122 to rotate around the first axis 1001. The second driving member is used to drive the second connecting arm 1246 to rotate, so as to drive the main lens 122 to rotate around the second axis 1002.

[0065] In this way, by driving the main lens 122 to rotate, the adjustment of the optical axis included angle α is realized, so as to adjust the coaxiality between the main lens 122 and the auxiliary lens 30, and the image blurring caused by the large optical axis included angle α can be avoided, thereby improving the image quality.

[0066] The first driving member and the second driving member may include a motor, a solenoid valve or other driving devices. The specific forms of the first driving member and the second driving member are not limited herein.

[0067] In one embodiment, the corresponding relationship between the preset image clarity and the lens coaxiality can be obtained, the clarity of the image obtained by the imaging module 12 when the main lens 122 is at the current position is calculated, and the coaxiality between the main lens 122 and the auxiliary lens 30 is determined according to the clarity and the corresponding relationship. In this way, the coaxiality can be determined by the clarity of the image, without the need for instrument measurement, which is simple and convenient, and can also save the internal space of the electronic device 100.

[0068] When the coaxiality between the main lens 122 and the auxiliary lens 30 is greater than or equal to the preset coaxiality threshold, the first driving device 124 is used to drive the main lens 122 to move, so that the coaxiality corresponding to the image obtained by the imaging module 12 is less than the coaxiality threshold. In this way, the adjustment of the coaxiality can be realized, so that the coaxiality is less than the coaxiality threshold.

[0069] Further, the image clarity and the lens coaxiality are in a negative correlation relationship. In other words, the more the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30 coincide, the smaller the coaxiality, the clearer the image, and the greater the clarity of the image.

[0070] In another embodiment, it is also possible to calculate the clarity of the image obtained by the imaging module 12 when the main lens 122 is at the current position. When the clarity is less than a preset clarity threshold, the first driving device 124 is used to drive the main lens 122 to move so that the clarity of the image obtained by the imaging module 12 is greater than the clarity threshold. In this way, by adjusting the position of the main lens 122, the image clarity is relatively high, eliminating the determination of coaxiality, and the execution time of the control method is shorter, which is beneficial to improving the adjustment speed.

[0071] In yet another embodiment, the first driving device 124 can be controlled to drive the main lens 122 to move. Calculate the clarity of the image obtained by the imaging module 12 when the main lens 122 is at each position, and use the position corresponding to the image with the maximum clarity as the target position. Control the first driving device 124 to drive the main lens 122 to move to the target position to achieve the adjustment of coaxiality. In this way, controlling the first driving device 124 to drive the main lens 122 to move to the position corresponding to the image with the maximum clarity can make the image captured by the imaging module 12 the clearest, thereby making the image quality the highest.

[0072] Please refer to Figure 7 , the second part 20 includes a second driving device 22 connecting the auxiliary lens 30. When the second part 20 is in the second position, the second driving device 22 is used to drive the auxiliary lens 30 to move to achieve focusing.

[0073] In this way, the second driving device 22 drives the auxiliary lens 30 to move to achieve focusing, so that the imaging module 100 captures a clear image, which is beneficial to improving the image quality.

[0074] In addition, when the second part 20 is in the second position, the second driving device 22 is used to drive the auxiliary lens 30 to move so that the coaxiality of the optical axis 1221 of the main lens 122 and the optical axis 31 of the auxiliary lens 30 is less than a preset coaxiality threshold.

[0075] In this way, the second driving device 22 drives the auxiliary lens 30 to move to adjust the coaxiality of the main lens 122 and the auxiliary lens 30, which can avoid image blurring caused by excessive coaxiality and is beneficial to improving the image quality obtained by the imaging module 12.

[0076] For the explanation and description of the second driving device 22, reference can be made to the explanation and description of the first driving device 124 above. To avoid redundancy, it will not be elaborated here.

[0077] Specifically, the coaxiality threshold includes a distance threshold. The second driving device 22 is used to drive the auxiliary lens 30 to move in a plane perpendicular to the optical axis of the auxiliary lens 30 so that the optical axis distance is less than the distance threshold. The optical axis distance is the distance between the optical axis of the main lens 122 and the optical axis of the auxiliary lens 30.

[0078] Specifically, the second driving device 22 includes a third driving member and a second transmission member. The second transmission member connects the third driving member and the auxiliary lens 30. The third driving member is configured to drive the second transmission member to move, so as to drive the auxiliary lens 30 to move in a plane perpendicular to the optical axis of the auxiliary lens 30, thereby making the distance between the optical axes less than a preset distance threshold.

[0079] Specifically, the coaxiality threshold includes an angle threshold. The second driving device 22 is configured to drive the auxiliary lens 30 to rotate, so that the included angle between the optical axes is less than the angle threshold. The included angle between the optical axes is the included angle between the optical axis of the main lens 122 and the optical axis of the auxiliary lens 30.

[0080] Specifically, the second driving device 22 includes a fourth driving member and a second connecting member. The second connecting member connects the fourth driving member and the auxiliary lens 30. The fourth driving member is configured to drive the second connecting member to rotate, so as to drive the auxiliary lens 30 to rotate, so that the included angle between the optical axes is less than the angle threshold.

[0081] The image sensor 126 may employ a Complementary Metal Oxide Semiconductor (CMOS) photosensitive element or a Charge-coupled Device (CCD) photosensitive element. The specific form of the image sensor 126 is not limited herein.

[0082] The electronic device 100 may include a basic shooting state and an enhanced shooting state.

[0083] When the second part 20 is not in the second position, according to the shooting instruction information, the image sensor 126 may acquire an image through the main lens 122. In this way, imaging can be performed only through the main lens 122, so that the user can also take pictures when the auxiliary lens 30 is not folded to the second position, making it more convenient for the user to use. At this time, the electronic device 100 is in the basic shooting state.

[0084] It can be understood that the second part 20 not being in the second position may mean that the second part 20 is in the first position, or that the second part 20 is in a position between the first position and the second position.

[0085] Furthermore, the shooting instruction information includes but is not limited to touch information, voice information, and key information. In other words, the shooting instruction can be triggered by the user clicking on the shooting icon, can also be triggered by the user's voice, or can also be triggered by the user pressing a key. The specific form and specific triggering method of the shooting instruction information are not limited herein.

[0086] When the second part 20 is in the second position, according to the shooting instruction information, the image sensor 126 can obtain an image through the auxiliary lens 30 and the main lens 122. In this way, the auxiliary lens 30 assists the imaging module 12 located in the first part 10 to obtain an image, making the shooting effect of the electronic device 100 better when folded. At this time, the electronic device 100 is in an enhanced shooting state.

[0087] It can be understood that the auxiliary lens 30 is located on the optical axis 1221 of the imaging module 12, which is equivalent to increasing the number of lenses for the imaging module 12 to form an image, facilitating the adjustment of optical parameters such as the focal length, aberration, and distortion of the imaging module 12, thereby making the details of the obtained image richer. Moreover, it can make the area where light is projected on the image sensor larger, enabling more pixels to be sensitive to light, thereby improving the resolution of the image. In this way, the clarity and quality of the image can be improved.

[0088] The electronic device 100 may further include a third driving device (not shown in the figure) connected to the image sensor 126, and the third driving device is used to drive the image sensor 126 to move to achieve focusing. For the explanation and description of the third driving device, reference can be made to the explanation and description of the first driving device 124 above. To avoid redundancy, it will not be elaborated here.

[0089] Please refer to again Figure 1 and Figure 2 , the electronic device 100 includes a first side 41 and a second side 42 facing away from each other, and the imaging module 12 is used to obtain an image through the second side 42. The first display 51 is located on the first side 41, and the second display 52 is located on the second side 42.

[0090] When the second part 20 is in the second position, the image sensor 126 is used to obtain a preview image through the auxiliary lens 30 and the main lens 122; the first display 51 is used to display the preview image.

[0091] In this way, the user can observe the preview image obtained by the imaging module 12 through the first display 51, and thus can adjust the position of the electronic device 100 according to the preview image, which is beneficial to improving the user experience.

[0092] Furthermore, when the second part 20 is in the second position, the second display 52 can be controlled to turn off the screen. In this way, the power consumption can be reduced.

[0093] It can be understood that when the electronic device 100 is in a folded state, the second display 52 is folded to the inside. Even if the second display 52 displays content, it is difficult for the user to observe the content displayed on the second display 52. Therefore, when the second part 20 is in the second position, turning off the screen of the second display 52 will not damage the user experience and can reduce the power consumption of the electronic device 100.

[0094] In Figure 2 the example, the first display 51 is provided on the second part 20. When the electronic device 100 is in a folded state, the user observes a preview image through the first display 51 provided on the second part 20. At this time, the imaging module 12 is a front camera.

[0095] It can be understood that the first display 51 can also be provided on the first part 10, as Figure 7 shown. The user observes a preview image through the first display 51 provided on the first part 10. At this time, the imaging module 12 is a rear camera.

[0096] Of course, the number of the first displays 51 can also be two. One of them is provided on the first part 10, and the other is provided on the second part 20. The specific number and specific position of the first display 51 are not limited herein.

[0097] In summary, the electronic device 100 according to the embodiment of the present application includes a first part 10, a second part 20, and an auxiliary lens 30.

When the second part 20 is in the first position, the electronic device 100 is in an unfolded state. When the second part 20 is in the second position, the electronic device 100 is in a folded state; the auxiliary lens 30 is located on the second part 20. When the second part 20 is in the second position, the auxiliary lens 30 is located on the optical axis of the imaging module 12 to assist the imaging module 12 in acquiring an image.
