[0016] Optionally, in the camera device, the light uniformizing component has a ring structure, a first end surface of the ring structure is the exit surface, and a hollow area of the first end surface is the mounting area.

[0017] Optionally, in the camera device, the first end surface is an inclined surface that is inclined towards the mounting area.

[0018] Optionally, in the camera device, the first end surface is a micro-structured surface having a concave-convex structure.

[0019] Optionally, in the camera device, the light beam input surface and / or the light beam output surface is a micro-structured surface having a concave-convex structure.

[0020] The remaining surface of the light guide component, except the light beam input surface and the light beam output surface, is a light surface.

[0021] Optionally, in the camera device, the camera device further comprises a light path control switch, the light path control switch is configured to control the on-off of the light path of the light beam transmitted from the light beam input surface to the second light beam exit surface.

[0022] In the working state of the second image sensor, the light path control switch controls the light path to be on.

[0023] In the non-working state of the second image sensor, the light path control switch controls the light path to be off.

[0024] The application further provides a camera shooting method, comprising:

[0033] The photographing method provided in the application can be used to supplement light for the first image sensor and the second image sensor through the light guiding component. Since the second image sensor is different from the first image sensor, the first photographing mode is different from the second photographing mode, and therefore, the photographing method provided in the application can complete corresponding light supplementing operations in different photographing modes.

[0039] The present application discloses a camera shooting device to realize light compensation operation in different modes. The present application also provides a camera shooting method.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] As shown in the following, Figure 1 The present application provides a camera shooting device, which includes a first image sensor 1, a second image sensor 2, a light compensation component 5 and a light guide component 4. The second image sensor 2 has a different working mode from the first image sensor 1. When the first image sensor 1 works, the light compensation component 5 is used for shooting light compensation of the first image sensor 1; and the light guide component 4 can guide at least part of the light beam of the light compensation component 5 to the second image sensor 2 for shooting light compensation when the second image sensor 2 works.

[0042] The camera shooting device provided by the present application can realize light compensation operation of the light compensation component 5 on the first image sensor 1 and the second image sensor 2 through the light guide component 4. Since the working mode of the second image sensor is different from that of the first image sensor, the camera shooting device provided by the present application can complete corresponding light compensation operation in the use of the first image sensor and the second image sensor in different working modes.

[0043] Moreover, the light compensation structure is not separately provided for the second image sensor, that is, the light compensation is performed by the light compensation component 5 when the second image sensor and the first image sensor work, and no additional light compensation structure and corresponding control structure are needed, thereby avoiding additional control cost.

[0044] In this embodiment, the first image sensor 1 can be an image sensor used by the camera device in the normal photography working mode, and the second image sensor 2 can be an image sensor used by the camera device in the photomicrography and / or macro photography working mode.

[0045] Furthermore, it can be understood that when the first image sensor 1 is working (in the normal photography mode), the working range of the supplementary lighting component 5 can reach more than 1m. However, when the second image sensor 2 is working (in the photomicrography and / or macro photography mode), the working range of the supplementary lighting component 5 is generally within 5mm. Therefore, when the second image sensor 2 is working, the object distance 'a' of the second image sensor 2 is smaller, and too strong light will cause overexposure of the image of the object captured by the second image sensor 2. The light guide component 4 guides at least a portion of the light beam from the supplementary lighting component 5, thereby achieving a softer and more uniform light beam effect, ensuring that the soft and uniform light beam illuminates the object being photographed.

[0046] like Figure 1 As shown, the second image sensor 2 and the first image sensor 1 are at a preset distance, and the supplementary lighting component 5 is arranged between the second image sensor 2 and the first image sensor 1. That is, the second image sensor 2, the supplementary lighting component 5, and the first image sensor 1 are arranged in sequence. Through the above arrangement, the light guide path size of the light guide component 4 meets the distance from the supplementary lighting component 5 to the second image sensor 2, effectively shortening the light guide path of the light guide component 4 guiding at least a portion of the light beam from the supplementary lighting component 5 to the second image sensor 2. This reduces the loss caused by the light beam being emitted from other surfaces of the light guide component 4 during the light guiding process, ensuring that the light guide component 4 performs effective supplementary lighting operation on the second image sensor 2 during the process of guiding at least a portion of the light beam from the supplementary lighting component 5 to the second image sensor 2.

[0047] Furthermore, since the light guide component 4 only needs to be arranged between the supplementary light component 5 and the second image sensor 2, the size requirement of the light guide component 4 is reduced, further reducing the manufacturing cost of the light guide component 4.

[0048] Furthermore, the second image sensor 2, the supplementary lighting component 5, and the first image sensor 1 are arranged sequentially, improving the structural compactness. That is, it reduces the installation area required for the second image sensor 2, the supplementary lighting component 5, and the first image sensor 1 in the camera device, and also facilitates the connection between the components in the camera device and the second image sensor 2, the supplementary lighting component 5, and the first image sensor 1.

[0049] Of course, the light supplementing component 5 can also be arranged at other positions. For example, the light supplementing component 5 is arranged at a side of the first image sensor 1 away from the second image sensor 2. At least part of the light beams emitted by the light supplementing component 5 can be guided to the second image sensor 2 by the light guiding component 4, so as to meet the shooting light supplementing requirement of the second image sensor 2 in operation. The above arrangement can effectively prevent the light beams emitted by the light supplementing component 5 and not guided to the second image sensor 2 by the light guiding component 4 from excessively supplementing the light of the second image sensor 2, and ensure the shooting effect of the second image sensor 2.

[0050] As shown in Figure 2 , the light guiding component 4 has a light beam input face 40 and a light beam output face. The light beam input face 40 is arranged corresponding to the light supplementing component 5. The light beams emitted by the light supplementing component 5 can enter the light guiding component 4 through the light beam input face 40, and the light guiding component 4 can transmit the light beams from the light beam input face 40 to the light beam output face. The light beam output face at least includes a second light beam exit face (not shown) arranged corresponding to the second image sensor. The light beams emitted by the second light beam exit face are used for the shooting light supplementing of the second image sensor.

[0051] Through the above arrangement, the light beams emitted by the light supplementing component 5 enter the light guiding component 4 through the light beam input face 40. At least part of the light beams entering the light guiding component 4 are transmitted to the second light beam exit face, and are emitted by the second light beam exit face and used for the shooting light supplementing of the second image sensor. Through the above arrangement, the effect that at least part of the light beams emitted by the light supplementing component 5 are guided to the second image sensor 2 is realized.

[0052] The light guiding component 4 can also be arranged as a combined structure composed of multiple mirrors. The light beams emitted by the light supplementing component 5 are reflected by the multiple mirrors, so that at least part of the light beams emitted by the light supplementing component 5 are guided to the second image sensor 2.

[0053] Of course, the light guiding component 4 can also be arranged as other structures, which are not limited herein and are within the protection scope.

[0054] It should be noted that, Figure 2 The enlarged part in the figure is the light beam input face 40, the first light beam exit face 43 and the exit face 31 of the light homogenizing component 3.

[0055] As shown in Figure 2 , the light beam input face 40 is a micro-structured face with concave-convex structure. Through the above arrangement, the light beams emitted by the light supplementing component 5 can enter the light guiding component 4 through the light beam input face 40. In order to reduce the light beams emitted by the light guiding component 4 from the remaining faces of the light guiding component 4 except the light beam input face 40 and the light beam output face during the guiding process of the light beams, the remaining faces of the light guiding component 4 except the light beam input face 40 and the light beam output face are light faces. Further, through the above arrangement, the reflection effect of the light beams in the light guiding component 4 is improved.

[0056] Preferably, the microstructure surface has a Fresnel microstructure.

[0057] The camera further comprises a light homogenizing component 3 connected with the second light beam exit surface, the light homogenizing component 3 is used for homogenizing the light beam transmitted by the light guide component 4 and emitting the light beam through an exit surface 31 of the light homogenizing component 3; wherein the light homogenizing component 31 has a mounting area for arranging the second image sensor 2, and the mounting area is located in the exit surface 31. Through the above arrangement, it is ensured that the light beam emitted by the exit surface 31 of the light homogenizing component 3 can uniformly supplement light to the second image sensor 2 on the basis of homogenizing the light, thereby improving the light supplementing effect.

[0058] In the embodiment, the exit surface 31 of the light homogenizing component 3 can be a complete plane, and the second image sensor 2 is located in the plane. That is, the light homogenizing component 3 completely wraps the mounting area for arranging the second image sensor 2 in the exit surface 31, so that the outer side of the edge of the mounting area has the light beam emitted by the exit surface 31, forming an aperture surrounding the second image sensor 2 in the circumferential direction, thereby improving the light homogenizing effect and the light supplementing effect.

[0059] Of course, the light homogenizing component 3 can also be a plurality of light homogenizing unit components arranged along the circumferential direction of the second image sensor 2, and the light homogenizing effect can also be achieved. The plurality of light homogenizing unit components are all connected with the second light beam exit surface of the light guide component 4, so that the light beam emitted by the second light beam exit surface is dispersed into the plurality of light homogenizing unit components and then emitted by the exit surfaces of the plurality of light homogenizing unit components.

[0060] The exit surface structure of the light homogenizing unit component is not limited, and can be a circular surface, a square surface or other shaped surface.

[0061] As shown in Figure 2 the exit surface 31 of the light homogenizing component 3 is a microstructure surface with a concave-convex structure. Through the above arrangement, the light beam in the light guide component 4 is emitted by the exit surface 31. In order to reduce the emission of the light beam by the remaining surface of the light homogenizing component 3 except the exit surface 31, the remaining surface of the light homogenizing component 3 except the exit surface 31 is a light surface. Further, through the above arrangement, it is ensured that the remaining surface of the light homogenizing component 3 except the exit surface 31 reflects the light beam in the light homogenizing component 3.

[0062] Preferably, the microstructure surface has a Fresnel microstructure.

[0063] As shown in Figure 2 and Figure 3As shown, the light uniformizing component 3 is a ring structure; the first end surface of the ring structure is the exit surface 31, and the hollow region of the first end surface is the mounting region. That is, the second image sensor 2 is arranged corresponding to the hollow region of the ring structure, so that the light uniformizing component 3 is arranged outside the second image sensor 2, and the uniformity of the light compensation is improved. Moreover, the second image sensor 2 and the light uniformizing component 3 can be relatively separated, so that the mounting operation of the second image sensor 2 and the light uniformizing component 3 to the camera device is facilitated.

[0064] Of course, the light uniformizing component 3 can also be a solid structure, and the first end surface (the exit surface 31) of the ring structure is a solid plane. The second image sensor 2 is directly mounted on the solid plane, so that the solid structure of the second image sensor 2 shields part of the exit surface 31.

[0065] Specifically, the first end surface (the exit surface 31) is a micro-structured surface having a concave-convex structure. Preferably, the micro-structured surface has a Fresnel microstructure.

[0066] It can be understood that, in microphotography and macro photography, the distance between the lens and the object is very close. In the embodiment, the second image sensor 2 is used for microphotography and / or macro photography, so that the image receiving end of the second image sensor 2 is very close to the object. As shown, Figure 3 That is, the size of the object distance a of the second image sensor 2 is small (usually about 3 mm). Preferably, the first end surface (the exit surface 31) is an inclined surface inclined towards the mounting region. Through the above arrangement, the light beams emitted by the exit surface 31 converge towards the plane 7 on which the object is placed, and the light compensation effect is ensured.

[0067] Since the size of the object distance a is small, slight shaking of the user's hand during the image capturing process of the camera device provided in the embodiment can cause the second image sensor 2 to be out of focus, and affect the image transmission effect of the second image sensor 2. Therefore, in order to prevent the out-of-focus caused by hand shaking, the camera device further comprises a mounting plate 8, and the light uniformizing component 3 is mounted on the mounting plate 8; the direction of the light beams emitted by the exit surface 31 is the direction towards the outer surface of the mounting plate 8; the light uniformizing component 3 has a supporting component protruding from the outer surface of the mounting plate 8, and the end surface of the second image sensor 2 has a predetermined distance from the protruding end of the supporting component. The predetermined distance is the object distance a of the second image sensor 2. That is, the light uniformizing component 3 forms a bracket structure supporting the camera device between the plane 7 on which the object is placed, and the positioning effect of the second image sensor 2 relative to the plane 7 is ensured.

[0068] Preferably, the light uniformizing component 3 forms a flash lamp cover, and the flash lamp cover is placed on the plane 7 (such as a table top), which can stabilize the object distance a and prevent the out-of-focus caused by hand shaking.

[0069] Further, the end surface of the second image sensor 2 is located on the inner surface of the mounting plate 8, wherein the inner surface of the mounting plate 8 is oppositely arranged to the outer surface of the mounting plate 8. That is, the inner surface of the mounting plate 8 and the outer surface of the mounting plate 8 are two symmetrical surfaces of the mounting plate 8. By the above arrangement, the end surface of the second image sensor 2 is protected. Further, the inner surface of the mounting plate 8 is a mounting surface for mounting the second image sensor 2.

[0070] The mounting plate 8 has a lens cover plate 41 arranged corresponding to the end surface of the second image sensor 2. The lens cover plate 41 is a transparent cover plate.

[0071] As shown in Figure 1 and Figure 2 , the light beam output surface further comprises a first light beam exit surface 43 arranged corresponding to the first image sensor 1, and the light beam exiting from the first light beam exit surface 43 is used for illuminating the first image sensor 1. In order to facilitate the light beam to exit, the first light beam exit surface 43 is a micro-structured surface with concave-convex structure. By the above arrangement, the light guide component 4 covers the illuminating component 5, and the illuminating component 5 is protected.

[0072] The illuminating component 5 can be a flash lamp, or other illuminating structure.

[0073] Preferably, the micro-structured surface has a Fresnel microstructure.

[0074] As shown in Figure 1 and Figure 2 , in order to avoid the light beam guided by the light guide component 4 to the second image sensor 2 affecting the imaging of the first image sensor 1, the imaging device further comprises a light path control switch 6, which is used for controlling the on-off of the light path of the light beam transmitted from the light beam input surface 40 to the second light beam exit surface.

[0075] Specifically, in the working state of the second image sensor 2, the light path control switch 6 controls the light path to be on. That is, in the working state of the second image sensor 2, the light guide component 4 guides at least part of the light beam of the illuminating component 5 to the second image sensor 2, so as to realize the illumination for the imaging of the second image sensor 2.

[0076] In the non-working state of the second image sensor 2, the light path control switch 6 controls the light path to be off. That is, in the non-working state of the second image sensor 2, the light guide component 4 cannot guide the light beam of the illuminating component 5 to the second image sensor 2, so as to avoid illuminating the second image sensor 2 and affecting the imaging of the first image sensor 1.

[0077] Of course, in order to avoid the influence on the shooting of the first image sensor 1, the light path control switch 6 can also control the light path to be disconnected in the working state of the first image sensor 1. That is, in the working state of the first image sensor 1, the light guide component 4 cannot guide the light beam of the light supplement component 5 to the second image sensor 2, avoiding the light supplement to the second image sensor 2 and also avoiding the influence on the shooting of the first image sensor 1.

[0078] And in the non-working state of the first image sensor 1, the light path control switch 6 controls the light path to be connected. That is, in the non-working state of the first image sensor 1, the light guide component 4 guides at least part of the light beam of the light supplement component 5 to the second image sensor 2, and the light supplement for the shooting of the second image sensor 2 will not affect the first image sensor 1.

[0079] The light path control switch 6 is correspondingly arranged with the light guide component 4, and by controlling the transmission of the light beam inside the light guide component 4, the light path from the light beam input surface 40 to the second light beam exit surface is realized. The transmission of the light beam is controlled to be connected or disconnected.

[0080] As shown in Figure 4 The embodiment of the present application also provides a photographing method, which comprises:

[0081] S1: In the first shooting mode, the light supplement component 5 is used for the light supplement for the shooting of the first image sensor 1.

[0082] S2: In the second shooting mode, the light guide component 4 guides at least part of the light beam of the light supplement component 5 to the second image sensor 2 for the light supplement for the shooting of the second image sensor 2, and the second image sensor 2 is different from the first image sensor 1.

[0083] The photographing method provided by the embodiment of the present application is used for the light supplement for the shooting of the first image sensor 1 in the first shooting mode, and at least part of the light beam of the light supplement component 5 is guided to the second image sensor 2 through the light guide component 4 for the light supplement for the shooting of the second image sensor 2 in the second shooting mode. That is, through the light guide component 4, the light supplement component 5 can realize the light supplement operation for the first image sensor 1 and the second image sensor 2. Since the second image sensor 2 is different from the first image sensor 1, the first shooting mode is different from the second shooting mode, and therefore, the photographing method provided by the embodiment of the present application can complete the corresponding light supplement operation in different shooting modes.

[0084] And, the light supplement structure is avoided to be separately arranged for the second image sensor, that is, the light supplement is performed through the light supplement component 5 when the second image sensor and the first image sensor work, and it is not necessary to additionally arrange the light supplement structure and the corresponding control structure, thereby avoiding the additional control cost.

[0085] In the embodiment, the first image sensor 1 can be an image sensor used by the camera in a normal photography working mode, and the second image sensor 2 can be an image sensor used by the camera in a macro photography working mode.

[0086] In order to avoid the light beam guided by the light guiding component 4 to the second image sensor 2 from affecting the image capturing of the first image sensor 1, a light path control switch 6 is further included, which is configured to control the on-off of the light path of the light beam passing through the light guiding component 4.

[0087] Specifically, in the first shooting mode, the light path control switch 6 controls the light path to be off. That is, in the non-working state of the second image sensor 2, the light guiding component 4 cannot guide the light beam of the light supplement component 5 to the second image sensor 2, avoiding the light supplement to the second image sensor 2 and the impact on the image capturing of the first image sensor 1.

[0088] In the second shooting mode, the light path control switch 6 controls the light path to be on. That is, in the working state of the second image sensor 2, the light guiding component 4 guides at least part of the light beam of the light supplement component 5 to the second image sensor 2, achieving the light supplement for the image capturing of the second image sensor 2.

[0089] Of course, in the non-first shooting mode, the light path control switch 6 can also control the light path to be on. In the non-second shooting mode, the light path control switch 6 controls the light path to be off.

[0090] Specifically, in order to avoid the impact on the image capturing of the first image sensor 1, in the non-first shooting mode, the first image sensor 1 is in a non-working state, and the light path control switch 6 controls the light path to be on. That is, in the non-working state of the first image sensor 1, the light guiding component 4 guides at least part of the light beam of the light supplement component 5 to the second image sensor 2, and the light supplement for the image capturing of the second image sensor 2 will not affect the first image sensor 1.

[0091] In the non-second shooting mode, the second image sensor 2 is in a non-working state, and the light path control switch 6 controls the light path to be off. That is, in the non-working state of the second image sensor 2, the light guiding component 4 cannot guide the light beam of the light supplement component 5 to the second image sensor 2, avoiding the light supplement to the second image sensor 2 and the impact on the image capturing of the first image sensor 1.

[0092] It can be understood that, in the first shooting mode (working mode of normal photography), the working range of the light supplementing component 5 can reach 1 m or more. In the second shooting mode (working mode of microphotography and / or macro photography), the working range of the light supplementing component 5 is generally within 5 mm, and therefore, in the second shooting mode, the object distance a of the second image sensor 2 is smaller, and too strong light can cause overexposure of the image of the object shot by the second image sensor 2. Through the guidance of the light guiding component 4, at least part of the light beams of the light supplementing component 5 guided by the light guiding component 4 can be attenuated, so as to have a softening and uniform effect on the light beams, so that the soft and uniform light beams are irradiated on the shot object.

[0093] In the second shooting mode (working mode of microphotography and / or macro photography), the end surface of the second image sensor 2 is very close to the shot object, and the object distance a is smaller. In the case of high light intensity, overexposure of the image is prone to occur. Therefore, in order to avoid the occurrence of overexposure, in the image shooting method provided by the embodiment of the present application, in the second shooting mode, the light intensity of the light beams emitted by the light supplementing component 5 is I1; in the first shooting mode, the light intensity of the light beams emitted by the light supplementing component 5 is I2; and I1

[0094] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
