Meanwhile, despite the widespread popularity of video social media, few camera modules for electronic devices such as smartphones and tablets currently feature an aperture. There is also a trend toward larger sensors. Pop-up mechanisms are one solution to addressing this increase in sensor size.
[0004] In such conventional electrical equipment, when an aperture assembly is provided in a camera assembly, a unit for driving the aperture assembly is also required, which leads to problems of increased space and manufacturing costs. Summary of the Invention

[0008] an aperture assembly fixed to the foldable cylinder and having a light-adjusting cam pin for controlling an aperture diameter of an aperture in the aperture assembly, wherein the aperture diameter of the aperture in the aperture assembly is adjusted by changing a relative position of the light-adjusting cam pin relative to the foldable cam pin in a rotational direction perpendicular to the optical axis;
[0009] a cam cylinder having a first cam groove configured to guide a foldable cam pin and a second cam groove configured to guide a light amount adjustment cam pin, the cam cylinder being configured so that the foldable cylinder slides within the cam cylinder along the optical axis;

[0043] The embodiments of the present disclosure will be described in detail, and examples of the embodiments will be illustrated in the accompanying drawings. Throughout the specification, identical or similar elements and elements having identical or similar functions are represented by similar reference numerals. The embodiments described herein with reference to the accompanying drawings are illustrative and intended to illustrate the present disclosure, but should not be construed as limiting the present disclosure.
[0044] Figure 1 is a plan view of a first side of an electrical device 10 according to an embodiment of the present disclosure, Figure 2 1 is a plan view of a second side of the electrical device 10 according to an embodiment of the present disclosure. The first side may be referred to as a back side of the electrical device 10, and the second side may be referred to as a front side of the electrical device 10.
[0045] like Figure 1 and Figure 2 As shown, the electrical device 10 may include a display 20 and a camera assembly 30. In this embodiment, the camera assembly 30 includes a first main camera 32, a second main camera 34, and a secondary camera 36. The first and second main cameras 32, 34 are capable of capturing images from a first side of the electrical device 10, while the secondary camera 36 is capable of capturing images from a second side of the electrical device 10. Therefore, the first and second main cameras 32, 34 are so-called external cameras, while the secondary camera 36 is a so-called internal camera. As an example, the electrical device 10 may be a mobile phone, a tablet computer, a personal digital assistant, or the like.
[0046] Each of the first main camera 32, the second main camera 34, and the sub-camera 36 has an imaging sensor that converts light that has passed through the color filter into an electrical signal. The signal value of the electrical signal depends on the amount of light that has passed through the color filter.
[0047] Although the electrical device 10 according to the present embodiment has three cameras, the electrical device 10 may have fewer than three cameras or more than three cameras. For example, the electrical device 10 may have two, four, five cameras, and so on.
[0048] Figure 3 FIG is a block diagram of an electrical device 10 according to this embodiment. Figure 3 As shown, in addition to the display 20 and the camera assembly 30, the electrical device 10 may further include a main processor 40, an image signal processor 42, a memory 44, a power supply circuit 46, and a communication circuit 48. The display 20, the camera assembly 30, the main processor 40, the image signal processor 42, the memory 44, the power supply circuit 46, and the communication circuit 48 are interconnected via a bus 50.
[0049] The main processor 40 executes one or more program instructions stored in the memory 44. By executing the program instructions, the main processor 40 implements various applications and data processing of the electrical device 10. The main processor 40 can be one or more computer processors. The main processor 40 is not limited to a single CPU core and can have multiple CPU cores. The main processor 40 can be the main CPU of the electrical device 10, an image processing unit (IPU), or a DSP provided with the camera assembly 30.
[0050] That is, the main processor 40 constitutes the controller of the electric device 10 in this embodiment.
[0051] The image signal processor 42 controls the camera assembly 30 and processes various image data captured by the camera assembly 30 to generate target image data. For example, the image signal processor 42 can apply demosaicing processing, noise reduction processing, automatic exposure processing, automatic focus processing, automatic white balance processing, high dynamic range processing, etc. to the image data captured by the camera assembly 30.
[0052] In this embodiment, the main processor 40 and the image signal processor 42 cooperate with each other to generate target image data of the object captured by the camera assembly 30. That is, the main processor 40 and the image signal processor 42 are used to capture an image of the object through the camera assembly 30 and apply various image processing to the captured image data.
[0053] exist Figure 3 In the example shown in FIG. 4 , the camera assembly 30 includes a driving unit 60 for driving a pop-up unit and an aperture assembly.
[0054] The driving unit 60 includes, for example, a motor that drives the pop-up unit and the aperture assembly. That is, the motor drives the pop-up unit and the aperture assembly. The driving unit 60 can be configured separately from the camera assembly 30.
[0055] In this way, the pop-up unit and the aperture assembly of the camera assembly 30 are driven by a single drive unit 60 (a single motor). Therefore, a motor that drives the pop-up unit and the aperture assembly is also used. This allows the size (thinness) of the electrical device 10 to be reduced, and the manufacturing cost of the electrical device 10 to be lowered.
[0056] The memory 44 stores program instructions to be executed by the main processor 40 and various data. For example, the data of the captured image is also stored in the memory 44.
[0057] The memory 44 may include a high-speed RAM memory and / or a non-volatile memory such as a flash memory and a disk memory. That is, the memory 44 may include a non-transitory computer-readable medium storing program instructions.
[0058] The power supply circuit 46 may include a battery, such as a lithium-ion rechargeable battery, and a battery management unit (BMU) for managing the battery.
[0059] Communication circuitry 48 is used to receive and transmit data for communication with a base station of a telecommunications network system, the Internet, or other devices via wireless communications. Wireless communications can utilize any communication standard or protocol, including but not limited to GSM (Global System for Mobile Communications), CDMA (Code Division Multiple Access), LTE (Long Term Evolution), LTE-Advanced, and 5G. Communication circuitry 48 may include an antenna and RF (Radio Frequency) circuitry.
[0060] Next, we will refer to Figures 4A to 11 The description focuses on an example of the configuration of the pop-up lens unit of the camera assembly 30 of the electric device 10 having the above-described configuration.
[0061] It should be noted that Figure 4A A state in which the foldable cylinder Y is accommodated in the cam cylinder C is shown. Figure 5A The collapsible cylinder Y is ejected from the cam cylinder C to the first imaging position P1 , and a state is shown in which the aperture diameter XO of the aperture is at a maximum value (first value). Figure 6A The state in which the collapsible cylinder Y is ejected from the cam cylinder C to the first imaging position P1 and the aperture diameter XO of the aperture is an intermediate value (second value) is shown. Figure 7A The state in which the collapsible cylinder Y is ejected from the cam cylinder C to the second imaging position P2 and the aperture diameter XO of the aperture is an intermediate value (second value) is shown. Figure 8A The foldable cylinder Y is ejected from the cam cylinder C to the second imaging position P2 , and the state in which the aperture diameter XO of the aperture is the minimum value (third value) is shown.
[0062] exist Figure 4A 、 Figure 5A 、 Figure 6A 、 Figure 7A and Figure 8A In the figure, other structures are omitted, such as the image sensor and driving unit of the camera assembly 30, and the lens barrel of the foldable cylinder Y, etc.
[0063] In addition, Figure 4B 、 Figure 5B 、 Figure 6B 、 Figure 7B and Figure 8B In the figure, the groove of the cam cylinder C is omitted.
[0064] For example, Figures 4A to 4DAs shown, the camera assembly 30 includes a foldable cylinder Y, an aperture assembly X, a cam cylinder C and a drive wheel W.
[0065] The foldable cylinder Y contains the lens barrel LB ( Figure 10A and Figure 10B ), and is cylindrically shaped and extends around the optical axis L of the lens barrel LB. The foldable cylinder Y moves along the optical axis direction DL of the optical axis L.
[0066] A foldable cam pin PY is provided on the foldable cylinder Y. The foldable cam pin PY extends in a direction perpendicular to the optical axis L.
[0067] For example, Figures 4A to 4D As shown, the aperture assembly X is fixed to the foldable cylinder Y. The aperture assembly X is provided with a light quantity adjustment cam pin PX for controlling the aperture diameter XO of the aperture to adjust the light quantity. The light quantity adjustment cam pin PX extends in a direction perpendicular to the optical axis L.
[0068] For example, Figure 9A 、 Figure 9B and Figure 9C As shown, the aperture assembly X adjusts the aperture diameter XO of the aperture by changing the relative position of the light adjustment cam pin PX with respect to the foldable cam pin PY in the rotation direction perpendicular to the optical axis L (the angle θ between the foldable cam pin PY and the light adjustment cam pin PX).
[0069] In this embodiment, for example, Figure 10A As shown, the aperture assembly X is located between the lenses of the lens barrel LB of the collapsible cylinder Y. On the other hand, for example, Figure 10B As shown, the aperture assembly X can be located on one side of the main body A of the foldable cylinder Y.
[0070] In this embodiment, for example, the image sensor Z is a solid-state imaging device, such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor, a CCD (Charge-Coupled Device) image sensor, or the like.
[0071] like Figure 4A and Figure 4B As shown, for example, the cam cylinder C has a cylindrical shape extending around the optical axis L. The cam cylinder C is fixed to the housing of the camera assembly 30 (ie, the camera assembly 30 is arranged in a housing provided in the electrical device 10).
[0072] For example, Figure 4CAs shown, the cam cylinder C is formed with first cam grooves M1a, M1b, M1c, and M1d for guiding the foldable cam pin PY. Furthermore, the cam cylinder C is formed with a second cam groove M2 for guiding the light adjustment cam pin PX. Within the cam cylinder C, the foldable cylinder Y slides within the cylindrical shape of the cam cylinder C along the optical axis L.
[0073] For example, Figure 4C As shown, the first cam grooves M1a, M1b, M1c, and M1d and the second cam groove M2 of the cam cylinder C are formed to penetrate the cylindrical shape of the cam cylinder C.
[0074] In particular, the first cam grooves M1a, M1b, M1c and M1d of the cam cylinder C include: a first portion M1a formed to extend in a direction inclined relative to the optical axis direction; a second portion M1b formed to extend in the rotational direction and connected to the first portion of the first cam groove; a third portion M1c formed to extend parallel to (in the same direction as) the first portion M1a of the first cam groove M1 and connected to the second portion M1b of the first cam groove M1; and a fourth portion M1d formed to extend in the rotational direction and connected to the third portion M1c of the first cam groove M1.
[0075] Furthermore, the second cam groove M2 of the cam cylinder C is formed to extend in parallel (in the same direction) with the first portion M1a and the third portion M1c of the first cam grooves M1a, M1b, M1c, and M1d.
[0076] The first portion M1a of the first cam grooves M1a, M1b, M1c and M1d and the second cam groove M2 are connected to each groove extending in the optical axis direction DL to insert the foldable cam pin PY and the light amount adjusting cam pin PX when assembling the camera assembly 30.
[0077] For example, Figure 4A and Figure 4B As shown, the drive wheel W has a cylindrical shape extending around the optical axis L. The cam cylinder C is located inside the cylindrical shape of the drive wheel W.
[0078] The driving wheel W is formed with a third cam groove M3 for guiding the foldable cam pin PY, and also with fourth cam grooves M4a, M4b, M4c, and M4d for guiding the light amount adjustment cam pin PX.
[0079] The third cam groove M3 and the fourth cam grooves M4 a , M4 b , M4 c , and M4 d of the driving wheel W are formed in the cylindrical inner portion thereof.
[0080] In particular, the third cam groove M3 of the driving wheel W is formed to extend in the optical axis direction DL.
[0081] In addition, the fourth cam grooves M4a, M4b, M4c and M4d of the driving wheel W include: a first part M4a, which is formed to extend in the optical axis direction DL; a second part M4b, which is formed to extend in the rotation direction and is connected to the first part M4a of the fourth cam grooves M4a, M4b, M4c and M4d; a third part M4c, which is formed to extend in the optical axis direction DL and is connected to the second part M4b of the fourth cam grooves M4a, M4b, M4c and M4d; and a fourth part M4d, which is formed to extend in the rotation direction and is connected to the third part M4c of the fourth cam grooves M4a, M4b, M4c and M4d.
[0082] The third cam groove M3 and the first portion M4a of the fourth cam grooves M4a, M4b, M4c and M4d are connected to each groove to insert the foldable cam pin PY and the light amount adjusting cam pin PX when the camera assembly 30 is assembled.
[0083] Here, for example, as mentioned above Figure 3 A drive unit 60 is shown for rotating the drive wheel W relative to the cam cylinder C around the optical axis L, thereby guiding the foldable cam pin PY through the first cam grooves M1a, M1b, M1c and M1d and the third cam groove M3, and guiding the light quantity adjustment cam pin PX through the second cam groove M2 and the fourth cam grooves M4a, M4b, M4c and M4d.
[0084] The driving unit 60 is, for example, a motor that rotates the driving wheel W around the optical axis L relative to the cam cylinder C.
[0085] For example, according to Figure 4A 、 Figure 5A 、 Figure 6A 、 Figure 7A 、 Figure 8A In the order of , the driving unit 60 rotates the driving wheel W relative to the cam cylinder C about the optical axis L in the first direction R1. Due to this rotation, the foldable cylinder Y moves relative to the cam cylinder C along the optical axis L from the reference position B ( Figure 4B ) moves to the first imaging position P1 ( Figure 5B ) (the foldable cylinder Y pops up); thereafter, when the driving wheel W further rotates in the first direction R1, in a state where the foldable cylinder Y pops up at the first imaging position P1, the aperture diameter XO of the diaphragm is increased by the first aperture diameter (the first value ( Figure 5A )) becomes the second opening diameter (second value ( Figure 6A)); thereafter, when the driving wheel W further rotates in the first direction R1, the retractable cylinder Y pops out from the first imaging position P1 to the second imaging position P2 along the optical axis L; thereafter, when the driving wheel W further rotates in the first direction R1, in the state where the foldable cylinder Y pops out at the second imaging position P2, the opening diameter XO of the diaphragm is changed from the second opening diameter (the second value ( Figure 7A )) becomes the third opening diameter (third value ( Figure 8A )).
[0086] exist Figure 4A In the example shown, the reference position B is the position where the foldable cylinder Y is accommodated in the cam cylinder C. Figure 5A and Figure 6A In the example shown, the first imaging position P1 is the position where the foldable cylinder Y is ejected from the cam cylinder C. Figure 7A and Figure 8A In the illustrated example, the second imaging position P2 is a position where the foldable cylinder Y is further ejected from the first imaging position P1.
[0087] More specifically, for example, according to Figure 4A 、 Figure 5A In this order, the driving unit 60 rotates the driving wheel W relative to the cam cylinder about the optical axis L. Due to this rotation, the foldable cam pin PY is guided by the first portion M1a of the first cam grooves M1a, M1b, M1c, and M1d and the third cam groove M3, and the light amount adjustment cam pin PX is guided by the second cam groove M2 and the first portion M4a of the fourth cam grooves M4a, M4b, M4c, and M4d ( Figure 4B 、 4C , 5B and 5C). In this case, in a state where the relative position of the light amount adjustment cam pin PX with respect to the foldable cam pin PY is fixed ( Figure 4B and Figure 5B ), the foldable cylinder Y moves along the optical axis L.
[0088] Next, for example, follow Figure 5A 、 Figure 6A In this order, the drive unit 60 rotates the drive wheel W relative to the cam cylinder about the optical axis L. Due to this rotation, the foldable cam pin PY is guided by the second portion M1b of the first cam grooves M1a, M1b, M1c, and M1d, and the light quantity adjustment cam pin PX is guided by the second portion M4b of the fourth cam grooves M4a, M4b, M4c, and M4d. In this case, the relative position of the light quantity adjustment cam pin PX with respect to the foldable cam pin PY changes, so as to control the aperture diameter XO (of the aperture of the aperture assembly X) in a state where the position of the foldable cylinder Y in the optical axis direction DL is fixed (the foldable cylinder Y is in the first imaging position P1). Figure 5A and 6A).
[0089] Next, for example, follow Figure 6A 、 Figure 7A In this order, the driving unit 60 rotates the driving wheel W relative to the cam cylinder about the optical axis L. Due to this rotation, the foldable cam pin PY is guided by the third portion M1c of the first cam grooves M1a, M1b, M1c, and M1d and the third cam groove M3, and the light amount adjustment cam pin PX is guided by the second cam groove M2 and the third portion M4c of the fourth cam grooves M4a, M4b, M4c, and M4d ( Figure 6B 、 6C , 7B and 7C). In this case, in a state where the relative position of the light amount adjustment cam pin PX with respect to the foldable cam pin PY is fixed ( Figure 6B and Figure 7B ), the foldable cylinder Y moves along the optical axis L.
[0090] Next, for example, follow Figure 7A 、 Figure 8A In this order, the drive unit 60 rotates the drive wheel W relative to the cam cylinder about the optical axis L. Due to this rotation, the foldable cam pin PY is guided by the fourth portion M1d of the first cam grooves M1a, M1b, M1c, and M1d, and the light quantity adjustment cam pin PX is guided by the fourth portion M4d of the fourth cam grooves M4a, M4b, M4c, and M4d. In this case, the relative position of the light quantity adjustment cam pin PX with respect to the foldable cam pin PY changes, so as to control the aperture diameter XO (of the aperture of the aperture assembly X) in a state where the position of the foldable cylinder Y in the optical axis direction DL is fixed (the foldable cylinder Y is in the second imaging position P2). Figure 7A and 8A ).
[0091] On the other hand, according to Figure 8A 、 Figure 7A 、 Figure 6A 、 Figure 5A 、 Figure 4A In the order, the driving unit 60 causes the driving wheel W to rotate around the optical axis L in a second direction R2 opposite to the first direction R1 relative to the cam cylinder starting from the state where the foldable cylinder Y is located at the second imaging position P2 (the foldable cylinder Y pops up).
[0092] When the driving wheel W is driven by the driving unit 60 to rotate in the second direction R2 relative to the cam cylinder about the optical axis L, the operation of the camera assembly 10 is opposite to the above-described operation in which the driving wheel W rotates in the first direction R1 .
[0093] Thus, when the driving wheel W rotates relative to the cam cylinder C, the foldable cylinder Y pops out gradually at two or more imaging positions P1 and P2, and the aperture diameter XO of the aperture of the aperture assembly X changes at the two or more imaging positions P1 and P2.
[0094] Thus, the camera assembly 30 of the electrical device 10 achieves a stepless aperture, that is, the aperture is not limited to two levels. Furthermore, the camera assembly 30 of the electrical device 10 can achieve different aperture values at the wide end and the far end. In particular, the camera assembly 30 of the electrical device 10 can suppress far-end aberration.
[0095] exist Figures 4D to 8D In the example of FIG, the position of the foldable cam pin PY in the optical axis direction DL is different from the position of the light amount adjustment cam pin PX in the optical axis direction DL. However, for example, Figure 11 As shown, the position of the foldable cam pin PY in the optical axis direction DL may be the same as the position of the light amount adjustment cam pin PX in the optical axis direction DL.
[0096] exist Figures 4A to 8A In the example shown in FIG, the first value is set to the maximum value of the aperture diameter XO of the aperture, the second value is set to the middle value of the aperture diameter XO of the aperture, and the third value is set to the minimum value of the aperture diameter XO of the aperture. However, the first value may be set to the minimum value of the aperture diameter XO of the aperture, the second value may be set to the middle value of the aperture diameter XO of the aperture, and the third value may be set to the maximum value of the aperture diameter XO of the aperture.
[0097] Furthermore, the relationship between the rotation direction (the first direction R1 and the second direction R2) of the driving wheel W and the sliding direction of the collapsible cylinder Y may be reversed.
