[0032] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0033] like Figure 1 and Figure 2 As shown, the present application provides a camera device 1, comprising:

[0034] Lens group 11,

[0035] The shading member 12 is a circular ring located at the first end of the lens group 11, wherein the ambient light enters the lens group 11 through the hollow area formed by the inner ring of the shading member 12

[0036] The photosensitive chip 13 is located at the second end of the lens group 11 , and the ambient light passes through the hollow area and the light beam of the lens group 11 and is projected onto the photosensitive chip 13 .

[0037] A camera device 1 provided in an embodiment of the present application includes a lens group 11, a shading member 12 and a photosensitive chip 13. The lens group 11 has a first end and a second end. The first end has the shading member 12, and the second end has the photosensitive chip 13. The shading member 12 is a circular ring structure. Ambient light will enter the lens group 11 through the hollow area formed by the inner ring of the shading member 12, while the circular ring area of ​​the shading member 12 cannot penetrate the ambient light. Therefore, the ambient light can pass through the hollow area formed by the inner ring of the shading member 12 and the lens group 11 and be projected onto the photosensitive chip 13 to perform imaging.

[0038] In a camera device 1 provided in the present application, an annular shading member 12 is provided at the first end of the lens group 11 to block ambient light, so that ambient light can only enter the lens group 11 from the hollow area formed by the inner ring of the annular ring, while the annular area of ​​the shading member 12 cannot penetrate the ambient light. Therefore, the shading member 12 blocks part of the ambient light that can be converted into stray light, thereby preventing the stray light from being projected onto the photosensitive chip 13, thereby avoiding the occurrence of glare problems, and further improving the photo quality of the camera device 1.

[0039] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the lens group 11 includes a plurality of lenses arranged based on a target sequence, the light shielding member is located on a first surface of a first lens 111, the first lens 111 is the first lens in the target sequence, and the first surface is an outer surface of the first lens 111;

[0040] The inner ring diameter of the shading element 12 is related to the first surface of the first lens 111 .

[0041] In this embodiment, the lens group 11 includes a plurality of lenses, and the plurality of lenses are arranged based on a target sequence. The plurality of lenses include a first lens 111 which is the first lens in the target sequence. The first lens 111 has a first surface and a second surface. The first surface is an outer surface of the first lens 111. A shading member 12 is provided on the first surface of the first lens 111, so that ambient light can pass through a hollow area formed by an inner ring of the shading member 12 of an annular structure and be projected onto the photosensitive chip 13, thereby realizing imaging. The first lens 111, which is the first lens in the target order in the lens group 11, is a lens that can receive light and undergo multiple reflections, so that the size and position of the shading member 12 are set according to the first surface of the first lens 111, and the inner ring diameter of the shading member 12 is also related to the first surface of the first lens 111. The lens group 11 has a field of view angle, and the light beam within the field of view angle will directly project onto the photosensitive chip 13, that is, the field of view angle is the angle range of receiving light formed by other lenses in the lens group 11 except the first lens 111, and the light beam outside the field of view angle will be reflected multiple times before being projected onto the photosensitive chip 13, that is, the light beam received by the first lens 111 will be reflected multiple times before being projected onto the photosensitive chip 13, and the light that is reflected multiple times is stray light, so that the inner ring diameter of the shading member 12 is set according to the first surface of the first lens 111, the inner ring of the shading member 12 is set within the field of view angle of the lens group 11, and the shading member 12 is set outside the field of view angle of the lens group 11. It is ensured that the shading member 12 will block the ambient light that can form stray light, thereby preventing the stray light from being projected onto the photosensitive chip 13. Other ambient light passes through the hollow area formed by the inner ring of the shading member 12 and the lens group 11 and is projected onto the photosensitive chip 13 for imaging, thereby avoiding the occurrence of glare problems and further improving the photo quality of the camera device 1.

[0042] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the ambient light passing through the hollow area formed by the inner ring of the shading member 12 directly passes through the first lens 111 .

[0043] In this embodiment, the camera device 1 includes a lens group 11, a light shielding member 12 and a photosensitive chip 13. The lens group 11 has a first end and a second end. The first end has a light shielding member 12, and the second end has a photosensitive chip 13. The light shielding member 12 is a circular ring structure. The lens group 11 has a plurality of lenses arranged in a target sequence. The first lens in the target sequence is a first lens 111. A light shielding member is provided on the first surface of the first lens 111, so that the light shielding member blocks ambient light that can form stray light to prevent the stray light from being projected onto the photosensitive chip 13. The ambient light within the field of view of the lens group 11 will pass through the hollow area formed by the inner ring of the light shielding member 12 and the lens group 11 and be projected onto the photosensitive chip 13, that is, the light beam passing through the hollow area formed by the inner ring of the light shielding member 12 will also directly pass through the first lens 111 after reaching the first lens 111 to reach the photosensitive chip 13 for imaging.

[0044] like Figure 1 As shown, in the embodiment of the present application, the ambient light passing through the hollow area formed by the inner ring of the shading member 12 is incident from the upper surface of the first lens 111 , passes through the first lens 111 once, and passes out from the second surface of the first lens 111 .

[0045] In this embodiment, the ambient light within the field of view of the lens group 11 will pass through the hollow area formed by the inner ring of the shading member 12 and the lens group 11 and be projected onto the photosensitive chip 13. The ambient light passing through the hollow area formed by the inner ring of the shading member 12 will enter from the first surface of the first lens 111, and then pass through the second surface of the first lens 111 after one transmission to reach the photosensitive chip 13 to achieve imaging. That is, the ambient light passing through the hollow area formed by the inner ring of the shading member 12 will not be reflected multiple times when it is projected onto the first light transmittance. Only the light that is projected onto the shading member 12 will be reflected multiple times after entering to form stray light, thereby ensuring the imaging quality.

[0046] like Figure 2 As shown, in the embodiment of the present application, the shading member 12 is made of an electrochromic material, and the shading member 12 has two electrical connection points 121 .

[0047] In this embodiment, the shading member 12 is made of an electrochromic material, so that it changes color after being powered on. When the light is normal, the shading member 12 is not powered on. At this time, the shading member 12 is a transparent structure, and the camera device 1 receives light for normal imaging. When the user uses the camera device 1 to take pictures outdoors in the sun or under an indoor light source, flare is generated, and a rainbow-like glare stripe will appear in the photo taken by the camera device 1. At this time, the two electrical connection points 121 of the shading member 12 are powered on. After power is turned on, the color of the shading member 12 changes from transparent to dark. At this time, it can block the stray light that will be refracted multiple times after entering, avoid the generation of flare, and avoid the appearance of a rainbow-like glare stripe in the photo, thereby improving the shooting quality and reducing the difficulty of the user taking pictures. In addition, the shading effect of the shading member 12 is reversible. After returning to a place where the light is normal, the power can be turned off, so that the shading member 12 becomes a transparent structure, thereby increasing the amount of light entering and further improving the shooting quality. Furthermore, when the user wants to capture glare, the power supply may not be turned on, thereby capturing the glare and improving the user's shooting freedom.

[0048] In this embodiment, the first and second electrical connection points 121 and 121 are respectively provided on the first and second surfaces of the shading member 12, and the first and second electrical connection points 121 are respectively connected to a power source, and the power source is respectively used to supply power to the first and second electrical connection points 121 and 121, so as to realize the electrochromic change of the shading member 12. This avoids the problem of being unable to be washed due to the use of a coating for shading in the related art, and the cost is low.

[0049] In this embodiment, the power supply is also connected to the switching device. When the user uses the camera device 1 to take pictures and finds that there is flare in the photo, the switching device is turned on. After the switching device is turned on, the power supply is controlled to turn on. The power supply supplies power to the first electrical connection point 121 and the second electrical connection point 121 of the shading member 12, so that the first electrical connection point 121 and the second electrical connection point 121 of the shading member 12 are energized, thereby changing the color of the shading member 12. The shading member 12 after the color change can block the ambient light that enters and will be refracted multiple times to produce stray light, thereby avoiding the generation of flare and avoiding the appearance of a rainbow-like glare stripe in the photo, thereby improving the shooting quality and reducing the difficulty of users taking pictures.

[0053] The shading member 12 is located at the opening, and the ambient light passes through the hollow area formed by the inner ring of the shading member 12 and is emitted to the first lens 111 .

[0054] like Figure 1 and Figure 2 As shown, in an electronic device provided by the present application, it includes a housing, a camera device 1 and a shading member 12, the shading member 12 is located at the opening, the camera device 1 is arranged in the housing, the camera device 1 includes a lens group 11 and a photosensitive chip 13, the ambient light can be emitted to the first lens 111 of the camera lens group 11 through the hollow area formed by the inner ring of the shading member 12, while the circular ring area of ​​the shading member 12 cannot pass the ambient light, so that the shading member 12 blocks part of the ambient light that can be converted into stray light, and avoids the stray light from being projected onto the photosensitive chip 13, thereby avoiding the occurrence of glare problems, and further improving the photo quality of the camera device 1. And the first lens 111 of the lens group 11 is exposed through the opening to receive the light beam from the hollow area formed by the inner ring of the shading member 12, thereby ensuring the imaging quality.

[0058] In this embodiment, the camera device 1 includes a transparent protective plate 14, a lens group 11 and a photosensitive chip 13. The transparent protective plate 14 is located at the opening of the shell to protect the lens group 11, the photosensitive chip 13 and the shading member 12.

[0059] In this embodiment, the transparent protection plate 14 is a transparent glass plate.

[0060] In the embodiment of the present application, the inner ring diameter of the shading element 12 is related to the first surface of the first lens 111 .

[0061] In this embodiment, the light shielding member 12 is located on the first surface of the first lens 111 which is the first lens in the target order in the first lens group 11, so that the size and position of the light shielding member 12 are set according to the first surface of the first lens 111, and the inner ring diameter of the light shielding member 12 is also related to the first surface of the first lens 111. The lens group 11 has a field angle, such as Figure 1 The FOV shown is the field of view angle, and the light beam within the field of view angle will directly hit the photosensitive chip 13, that is, the field of view angle is the angle range of received light formed by other lenses in the lens group 11 except the first lens 111, and the light beam outside the field of view angle will be reflected multiple times before hitting the photosensitive chip 13, that is, the light beam received by the first lens 111 will be reflected multiple times before hitting the photosensitive chip 13, and the light that is reflected multiple times is stray light, so the inner ring diameter of the shading member 12 is set according to the first surface of the first lens 111, the inner ring of the shading member 12 is set within the field of view angle of the lens group 11, and the shading member 12 is set outside the field of view angle of the lens group 11.

Other ambient light passes through the hollow area formed by the inner ring of the shading member 12 and the lens group 11 and is projected onto the photosensitive chip 13 for imaging, thereby avoiding the occurrence of glare problems and further improving the photo quality of the camera device 1.

[0062] In addition, the inner ring diameter of the shading member 12 is also related to factors such as the distance between the transparent protection plate 14 and the lens group 11 and the incident angle of stray light.
