Description

Technical Field

[0001] This application belongs to the field of camera technology, and more specifically relates to a camera and an electronic device. Background Technology

[0002] With the development of smartphones, photography has become an indispensable function of smartphones and is used more and more in daily life. With the popularization of cameras, the market demands higher and higher photo quality.

[0003] In related technologies, periscope cameras are often used to improve the telephoto capabilities of smartphones. However, periscope cameras usually have a fixed aperture, which results in a fixed depth of field in smartphone imaging, thus affecting the imaging effect of electronic devices. Summary of the Invention

[0004] This application aims to provide a camera and electronic device that can solve the technical problem of fixed depth of field in electronic device imaging.

[0005] In a first aspect, embodiments of this application provide a camera, including:

[0006] Lens assembly;

[0007] The light-sensing component is located on the light-emitting side of the lens assembly;

[0008] A reflector is placed on the light-incident side of the lens assembly. The reflector is used to reflect light onto the lens assembly.

[0009] An aperture assembly includes a drive member, a first housing, and an opening / closing mechanism. The first housing and the opening / closing mechanism are disposed on the side of the reflex mirror facing the lens group. The drive member and the opening / closing mechanism are drivenly connected. The opening / closing mechanism is disposed in the first housing. The drive member is used to drive the opening / closing mechanism to move, so as to adjust the aperture of the aperture assembly.

[0010] Secondly, this application provides an electronic device, comprising:

[0011] Processor; and

[0012] As provided in the first aspect embodiment, the camera, processor, and camera are electrically connected.

[0013] The camera provided in this application includes a lens assembly, a photosensitive component, and a reflector. The photosensitive component is located on the light-emitting side of the lens assembly, and the reflector is located on the light-incoming side of the lens assembly. The reflector can reflect light onto the lens assembly, and the light passes through the lens assembly and then illuminates the photosensitive component, thereby achieving image formation.

[0014] The camera also includes an aperture assembly, which includes a driver, a first housing, and an opening / closing mechanism. The first housing and the opening / closing mechanism are both located on the side of the mirror facing the lens group. The driver and the opening / closing mechanism are driven to move, thereby adjusting the aperture of the aperture assembly. Since depth of field and aperture are inversely related, by adjusting the aperture of the aperture assembly, the depth of field of the camera image can be dynamically adjusted, increasing the richness of the camera image and improving the image quality.

[0015] Furthermore, the first housing and opening / closing mechanism of the aperture assembly are located on the side of the reflex mirror facing the lens group. That is, the first housing and opening / closing mechanism are located between the reflex mirror and the lens group. Therefore, the aperture assembly will not affect the thickness of the camera.

[0032] The following is combined with Figures 1 to 8 This application describes a camera 10 and an electronic device 1 according to embodiments thereof.

[0033] Firstly, such as Figure 1 , Figure 2 and Figure 3 As shown, this application provides a camera 10, including: a lens group 11; a photosensitive component 12 disposed on the light-emitting side of the lens group 11; a reflector 13 disposed on the light-incident side of the lens group 11, the reflector 13 being used to reflect light to the lens group 11; and an aperture assembly 14, the aperture assembly 14 including a driving member 141, a first housing 142 and an opening and closing mechanism 147, the first housing 142 and the opening and closing mechanism 147 being disposed on the side of the reflector 13 facing the lens group 11, the driving member 141 and the opening and closing mechanism 147 being drivenly connected, the opening and closing mechanism 147 being disposed on the first housing 142, the driving member 141 being used to drive the opening and closing mechanism 147 to move, so as to adjust the aperture of the aperture assembly 14.

[0034] The camera 10 provided in this application includes a lens group 11, a photosensitive component 12, and a reflector 13. The photosensitive component 12 is disposed on the light-emitting side of the lens group 11, and the reflector 13 is disposed on the light-incident side of the lens group 11. The reflector 13 can reflect light to the lens group 11, and the light shines on the photosensitive component 12 after passing through the lens group 11, thereby realizing image formation.

[0035] The camera 10 also includes an aperture assembly 14, which includes a driver 141, a first housing 142, and an opening / closing mechanism 147. The first housing 142 and the opening / closing mechanism 147 are both located on the side of the reflector 13 facing the lens group 11. The driver 141 and the opening / closing mechanism 147 are driven to move, thereby adjusting the aperture of the aperture assembly 14. Since depth of field and aperture are inversely related, by adjusting the aperture of the aperture assembly 14, the depth of field of the image captured by the camera 10 can be dynamically adjusted, increasing the richness of the image captured by the camera 10 and improving the imaging effect.

[0036] Furthermore, the first housing 142 and the opening and closing mechanism 147 of the aperture assembly 14 are disposed on the side of the reflector 13 facing the lens group 11. That is, the first housing 142 and the opening and closing mechanism 147 are disposed between the reflector 13 and the lens group 11. Therefore, the aperture assembly 14 will not affect the thickness of the camera 10.

[0037] The aperture size is inversely related to the depth of field. A larger aperture (e.g., smaller f-numbers like f / 1.2 or f / 2.8) allows more light to enter the lens group 11, resulting in a shallower depth of field. In this case, only a small area near the focal point is sharp, while the foreground and background are blurred, thus highlighting the subject and creating a shallow depth of field effect. This is commonly used in portrait and macro photography to emphasize the subject and create a soft background blur. For example, when shooting portraits, using a large aperture keeps the subject sharp and the background blurred, focusing the viewer's attention on the subject. Conversely, a smaller aperture (e.g., larger f-numbers like f / 11 or f / 16) allows less light to enter the lens group 11, resulting in a deeper depth of field. In this case, a larger area from the foreground to the background remains relatively sharp, suitable for shooting landscapes, architecture, and other scenes requiring overall sharpness. For example, when shooting expansive landscapes, a small aperture allows both near and far objects to be clearly distinguished, showcasing rich detail and depth.

[0038] This application adds an aperture component 14 to the camera 10, which allows for aperture adjustment, thereby achieving the effect of adjusting the depth of field.

[0039] Furthermore, when the camera 10 photographs high-power light-emitting devices such as lasers or directly photographs the sun, the excessive amount of light entering the camera can easily damage the photosensitive component 12. In this embodiment, the aperture component 14 can adjust the amount of light entering the lens group 11, thereby reducing the risk of the photosensitive component 12 being burned or damaged.

[0040] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, the opening and closing mechanism 147 includes: a rotating ring 148 rotatably connected to the first housing 142, the rotating ring 148 including a first tooth 150, a driving member 141 connected to the rotating ring 148, the driving member 141 being used to drive the rotating ring 148 to rotate; a gear 152 fixed inside the first housing 142, the first tooth 150 meshing with one side of the gear 152; and a blade 153 movably connected inside the first housing 142, the blade 153 including a second tooth 154, the second tooth 154 meshing with the other side of the gear 152; wherein, when the driving member 141 drives the rotating ring 148 to rotate, the rotating ring 148 drives the gear 152 to rotate, the gear 152 drives the blade 153 to move, and the movement of the blade 153 is used to adjust the aperture of the aperture assembly 14.

[0041] Specifically, the opening and closing mechanism 147 includes a rotating ring 148, a gear 152, and a blade 153. The rotating ring 148 includes a first tooth 150, and the blade 153 includes a second tooth 154. The rotating ring 148 meshes with one side of the gear 152 through the first tooth 150, and the blade 153 meshes with the other side of the gear 152 through the second tooth 154. The driving member 141 is connected to the rotating ring 148 and is used to drive the rotating ring 148 to rotate. When the rotating ring 148 rotates, it drives the gear 152 to rotate through the first tooth 150. When the gear 152 rotates, it drives the blade 153 to move through the second tooth 154, thereby realizing the opening and closing of the blade 153. The opening and closing of the blade 153 can change the amount of light entering the aperture assembly 14, thereby realizing the adjustment of the aperture of the aperture assembly 14.

[0042] In this configuration, gears 152 and blades 153 are arranged in a one-to-one correspondence, meaning that one gear 152 meshes with one blade 153. A first tooth 150 meshes with one gear 152, or the inner side of the rotating ring 148 is provided with a full circle of first teeth 150, and all gears 152 mesh with one first tooth 150.

[0043] The number of gears 152 and blades 153 can be multiple, such as 2, 3, 4, 5, 6, 7 or 8, etc.

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, according to some embodiments of this application, the opening and closing mechanism 147 further includes: a slide 155 disposed in the first housing 142; a slider 156 slidably connected to the slide 155, and the slider 156 and the blade 153 are connected; wherein, when the driving member 141 drives the rotating ring 148 to rotate, the gear 152 rotates and the blade 153 moves along the slide 155.

[0045] Specifically, the opening and closing mechanism 147 also includes a slide 155 and a slider 156. The slide 155 is fixed to the first housing 142, and the slider 156 is slidably connected to the slide 155. The slider 156 can slide on the slide 155. That is, the slide 155 and the slider 156 support the blade 153 and improve the stability of the blade 153. When the driving member 141 drives the rotating ring 148 to rotate, the first tooth 150 drives the gear 152 to rotate. The gear 152 drives the blade 153 to rotate through the second tooth 154. The blade 153 moves along the slide 155, thereby adjusting and realizing the adjustment of the aperture.

[0046] The slider 156 can be fitted onto the slide rail 155. In order to improve the stability of the blade 153, two sliders 156 can be set on the slide rail 155 to increase the support force on the blade 153 and improve the stability of the blade 153.

[0047] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, the first housing 142 includes a first channel 144; the rotating ring 148 includes: a ring body 149 disposed inside the first housing 142, with a first tooth 150 disposed on the inner side of the ring body 149; a protrusion 151 disposed on the outer side of the ring body 149, the protrusion 151 extending out of the first housing 142 from the first channel 144, a driving member 141 connected to the protrusion 151, the driving member 141 being used to drive the ring body 149 to rotate inside the first housing 142 through the protrusion 151.

[0048] Specifically, the first housing 142 includes a first channel 144, and the rotating ring 148 includes a ring body 149 and a protrusion 151. The ring body 149 is rotatably disposed within the first housing 142, and a first tooth 150 is disposed on the inner side of the ring body 149, so that the ring body 149 and the first tooth 150 can rotate synchronously. The protrusion 151 is disposed on the outer side of the ring body 149, and the protrusion 151 extends out of the first housing 142 from the first channel 144. The protrusion 151 can move along the first channel 144, so that the protrusion 151 can drive the ring body 149 to move. The first tooth 150 and the ring body 149 rotate synchronously, and the first tooth 150 drives the gear 152 to rotate. The gear 152 drives the blade 153 to move. The entire movement process can be achieved only through the movement of the protrusion 151, reducing the space occupied by the opening and closing mechanism 147 during its movement, reducing the volume of the opening and closing mechanism 147, and reducing the volume of the camera 10.

[0049] like Figure 2 , Figure 3 and Figure 6 As shown, according to some embodiments of this application, the first housing 142 further includes: a fixing ring 143, a first channel 144 located in the fixing ring 143, and a ring body 149 disposed within the fixing ring 143; a plate 145 fixed to the fixing ring 143, a gear 152 rotatably disposed on the plate 145 via a rotating shaft 158, the plate 145 including a light-transmitting portion 146, and the blade 153 adjusting the aperture of the aperture assembly 14 by adjusting the shading area of ​​the light-transmitting portion 146.

[0050] Specifically, the first housing 142 also includes a fixing ring 143 and a plate 145. The first channel 144 is disposed around the fixing ring 143, the ring body 149 is disposed inside the fixing ring 143, and the plate 145 is disposed inside the fixing ring 143, or the plate 145 is fixed to one end of the fixing ring 143. The gear 152 is limited to the plate 145 by a rotating shaft 158. Furthermore, the plate 145 has a light-transmitting part 146 at the middle position, and the blade 153 is disposed corresponding to the light-transmitting part 146. The movement of the blade 153 can change the occlusion area of ​​the light-transmitting part 146, thereby realizing the adjustment of the aperture.

[0051] The plate 145 can be a single plate located on one side of the gear 152 and the blade 153. Alternatively, there can be two plates 145 located on either side of the gear 152 and the blade 153, respectively.

[0052] The slide 155 is fixed to the plate 145.

[0053] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, a ball bearing 157 is provided between the ring body 149 and the fixed ring 143, and the ring body 149 and the fixed ring 143 are rotatably connected by the ball bearing 157.

[0054] Specifically, a ball bearing 157 is provided between the ring body 149 and the fixed ring 143. The ring body 149 and the fixed ring 143 are rotatably connected by the ball bearing 157, thereby reducing the friction between the ring body 149 and the fixed ring 143 and improving the smoothness of the operation of the opening and closing mechanism 147.

[0055] The ball bearing 157 can have multiple bearings, such as 3, 4, 5 or 6.

[0056] Furthermore, a first groove can be provided on the outer side of the ring 149, and a second groove can be provided on the inner side of the fixing ring 143. The ball 157 is disposed in the first groove and the second groove, so that the ring 149 is limited to the fixing ring 143 only by the ball 157, thereby minimizing the friction on the ring 149.

[0057] According to some embodiments of this application, the driving component 141 is a stepper motor, and the driving component 141 adjusts the position of the blade 153 by the number of steps to adjust the aperture of the aperture assembly 14; wherein, the minimum aperture of the aperture assembly 14 is less than or equal to f / 5.6.

[0058] Specifically, the driving component 141 is a stepper motor. By controlling the number of steps of the driving component 141, the position of the blade 153 can be controlled, thereby adjusting the blade 153 to a set position to achieve a specific aperture.

[0059] The aperture assembly 14 has a minimum aperture of f / 5.6 or less, which effectively reduces the amount of light that hits the photosensitive assembly 12, thereby reducing the possibility of damage to the photosensitive assembly 12.

[0060] The drive component 141 can be connected to the protrusion 151 through a transmission assembly. The drive component 141 is used to drive the movement of the protrusion 151 and can adopt any structure as required.

[0061] like Figure 1 and Figure 7 As shown, according to some embodiments of this application, the camera 10 further includes: a second housing 16, a lens group 11, a photosensitive component 12, a reflector 13 and an aperture component 14 disposed within the second housing 16; wherein, the second housing 16 includes a first opening 161, and the reflector 13 is used to reflect light entering the first opening 161 to the lens group 11.

[0062] Specifically, the camera 10 also includes a second housing 16, in which the lens group 11, the photosensitive component 12, the reflector 13 and the aperture component 14 are all disposed. The second housing 16 includes a first opening 161, and the reflector 13 is tilted to correspond to the first opening 161, thereby reflecting the light entering the first opening 161 to the lens group 11. Through the reflection of the reflector 13, the periscope-style camera 10 is realized.

[0063] like Figure 1 As shown, according to some embodiments of this application, the drive member 141 is disposed on the side of the reflector 13 away from the lens group 11.

[0064] Specifically, the drive unit 141 is located on the side of the reflector 13 away from the lens group 11. Since the reflector 13 is usually tilted, placing the drive unit 141 on the side of the reflector 13 away from the lens group 11 can make reasonable use of the space inside the camera 10 and reduce the size of the camera 10.

[0065] According to some embodiments of this application, the photosensitive assembly 12 includes a filter 121 and a photosensitive chip 122, with the filter 121 disposed between the photosensitive chip 122 and the lens assembly 11. The filter 121 is an infrared filter.

[0066] like Figures 1 to 7As shown, according to some embodiments of this application, the camera 10 includes a reflector 13, an aperture assembly 14, a lens group 11, a filter 121, and a photosensitive chip 122. The aperture assembly 14 includes an opening and closing mechanism 147 and a driving member 141. The opening and closing mechanism is disposed above the reflector 13. The driving member 141 controls the aperture size of the opening and closing mechanism 147. Light shines on the reflector 13, is reflected by the reflector 13, and then enters the lens group 11. After passing through the filter 121, the light shines on the photosensitive chip 122, thereby forming an image. This allows for multiple aperture changes through the opening and closing mechanism 147.

[0067] It is also possible to design separate control for different gears 152, without being limited to the number of gears 152, the shape of blades 153, or the number and shape of blades 153, thereby changing the shape of the blades 153 that form the aperture, achieving multiple aperture shapes, and realizing different starburst phenomena during shooting.

[0068] Optionally, the opening and closing mechanism 147 includes four gears 152 and four blades 153, wherein the gears 152 are spaced 5 mm apart and the blades 153 are 2.5 mm wide. The specific dimensions of the gears 152 and the blades 153 can be adjusted according to the actual situation.

[0069] The gear 152 rotates to drive the blade 153 to move, thus opening and closing. The blade 153 can be a black-plated, opaque blade to block light. The blade 153 can be a polygonal structure.

[0070] The slide rail 155 and the slider 156 can activate the function of fixing and supporting the blade 153. The slide rail 155 and the slider 156 are not only used to fix the blade 153, but also provide a constant support force for the blade 153 during rotation by cooperating with the ball bearing 157, reducing the possibility of aperture instability caused by friction vibration.

[0071] The protrusion 151 of the rotating ring 148 is used for the rotation of the ring body 149, the rotation of the gear 152, and the movement of the blade 153.

[0072] The ball bearing 157 is used to reduce friction between the rotating ring 148 and the fixed ring 143.

[0073] The drive unit 141 controls the rotation of the rotating ring 148 through the protrusion 151. The drive unit 141 can be a stepper motor. The drive accuracy of the drive unit 141 is 0.9° / step. The speed of the drive unit 141 is controlled by the pulse width modulation (PWM) signal.

[0074] The opening / closing mechanism 147 is positioned above the reflector 13. The drive component 141 is connected to the protrusion 151, controlling its movement to rotate the gear 152. Three or four gears 152 can be configured, and the number of gears 152 can be greater than or equal to four. Figure 2 and Figure 3 As shown, when moving clockwise, gear 152 drives blade 153 to move counterclockwise, thereby putting the opening and closing mechanism 147 in the open state. Different positions of blade 153 can correspond to different aperture sizes, and multiple settings can be set as needed. When fully open, the open state is the maximum aperture state, as shown in the image. Figure 3 As shown.

[0075] Specifically, the opening and closing mechanism 147 can be set to seven levels, such as f / 2.8, f / 4.0, f / 5.6, f / 8, f / 11, f / 16 and f / 22, with a 0.5mm interval between each level. The rotation speed of the drive unit 141 is controlled by a PWM signal to achieve precise adjustment.

[0076] A large aperture of f / 2.8 is suitable for capturing light, ideal for shooting in low-light environments and when a certain degree of optical bokeh is desired; f / 4.0 is suitable for travel landscapes and architectural details; f / 5.6 to f / 8 provide overall sharpness for commercial product photography, ensure clarity across the foreground, middle ground, and background for natural landscapes, and preserve full detail in hair and clothing for studio portraits; diffraction softening begins to appear from f / 11 to f / 16, making it suitable for scenes requiring a high depth of field; f / 22 is suitable for shooting starburst effects. In short, large apertures capture light, medium apertures provide balance, and small apertures expand the field of view.

[0077] The camera 10 provided in this application embodiment can realize the variable aperture of the periscope camera 10, which can be selected by the user according to the actual situation, thereby improving the shooting effect of the electronic device 1.

[0078] Furthermore, by adjusting the shape of the blades 153, the shape of the blades 153 that form the aperture can be changed, thus achieving multiple apertures and creating different starburst effects when taking photos.

[0079] A small aperture can reduce the risk of the photosensitive element 12 being burned. In high-intensity light environments, the aperture can be automatically reduced to f / 5.6 or below, thereby reducing the risk of burning by partially blocking the area of ​​the photosensitive element 12.

[0080] Secondly, such as Figure 8 As shown, this application provides an electronic device 1, including: a processor 20; and a camera 10 as provided in the first aspect embodiment, wherein the processor 20 and the photosensitive component 12 of the camera 10 are electrically connected.

[0081] The electronic device 1 provided in this application includes the camera 10 as provided in the first aspect embodiment, and therefore has all the beneficial effects of the camera 10 as provided in the first aspect embodiment, which will not be described in detail here.

[0082] In this application embodiment, electronic device 1 can be a terminal or other devices besides a terminal.
