The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

An image pickup apparatus and an electronic device according to an embodiment of the present application are described below with reference to fig. 1 to 4.

As shown in fig. 1, fig. 2 and fig. 3, a first aspect of the present disclosure provides an image capturing apparatus, which includes a housing 100, a photosensitive assembly 102, a single-focus lens set 104, a multi-focus lens set 106 and a driving assembly 108.

The photosensitive assembly 102, the multi-focal lens set 106 and the driving assembly 108 are all disposed in the casing 100; at least a portion of the single-focus lens group 104 is disposed in the housing 100, the single-focus lens group 104 is disposed on the top of the photosensitive element 102, and the multi-focus lens group 106 is disposed between the single-focus lens group 104 and the photosensitive element 102. The driving assembly 108 is used for driving the single-focal lens group 104 to move transversely; further, the curvature of the multifocal lens group 106 is different in the moving direction of the multifocal lens group. Thus, by driving the single-focus lens group 104 to move laterally, the light exit position of the single-focus lens group 104 corresponds to the light entrance position of the multi-focus lens group 106 with different curvatures, and the single-focus lens group 104 and the multi-focus lens group 106 with different curvatures are used in cooperation.

In particular, the image capturing apparatus according to the embodiment of the present invention can drive the single-focus lens group 104 to move laterally through the driving assembly 108, and the moving direction of the single-focus lens group 104 is parallel to the photosensitive surface of the photosensitive chip 126 of the photosensitive assembly 102, so that the single-focus lens group 104 and the multi-focus lens group 106 are used in cooperation at different positions with different curvatures, and thus the entire image capturing apparatus can achieve optical continuous zooming, and the single-focus lens group 104 and the multi-focus lens group 106 cooperate to have different image capturing functions (including but not limited to distance image capturing and near image capturing), so that the image capturing apparatus can integrate the functions of different types of image capturing apparatuses in the related art, thereby replacing different image capturing apparatuses adopted in the related art.

Therefore, on one hand, the using number of the image pickup devices in the related electronic equipment can be reduced, even only one image pickup device is arranged on the electronic equipment, and the volume of the electronic equipment can be reduced; meanwhile, the occupied size of the camera device in the electronic equipment can be reduced, more space is reserved for other components, and the internal layout of the electronic equipment is facilitated. On the other hand, the number of the holes of the casing 100 of the electronic device can be reduced, the waterproof and dustproof effects of the electronic device can be enhanced, and the sealing performance and the reliability of the whole electronic device can be improved. In addition, the driving assembly 108 drives the monofocal lens group 104 to move laterally, so that a protruding portion required to be arranged on an electronic device in the related art is omitted, and the aesthetic degree of an electric device applying the shooting device is greatly improved.

As shown in fig. 1, 2 and 3, the driving unit 108 drives the single-focal-lens group 104 to move laterally to change the function of the image pickup apparatus, and the adjustment of the lateral movement does not change the distance between the single-focal-lens group 104 and the multi-focal-lens group 106, which requires a low height of the image pickup apparatus. Therefore, when the camera device is applied to electronic equipment such as a mobile phone and a tablet personal computer, the thickness of the electronic equipment cannot be increased. That is, in the case that the focal length of the single-focus lens group 104 and the focal length of the multi-focus lens group 106 are changed, the thickness angle of the image pickup apparatus and the electronic device using the image pickup apparatus can be still ensured, which is beneficial to realizing the miniaturization design of the image pickup apparatus and the electronic device using the image pickup apparatus.

Therefore, the image pickup apparatus provided by the embodiment of the present application drives the single-focus lens group 104 to move laterally through the driving assembly 108, so that the entire image pickup apparatus can realize optical continuous zooming, and the volume of the image pickup apparatus is reduced. When the camera device is applied to the electronic equipment, more spaces can be reserved for other parts in the electronic equipment, the internal layout of the electronic equipment is convenient, the number of the open holes of the shell 100 of the electronic equipment can be reduced, the waterproof and dustproof effects of the electronic equipment are enhanced, and the overall tightness and reliability of the electronic equipment are improved. In addition, the single-focus lens group 104 is driven to move transversely to zoom the image pickup device, so that the image pickup device can be placed in the shell 100 of the electronic equipment when in use, and the electronic equipment has a better appearance.

As one possible embodiment, as shown in fig. 4, the curvature of at least a portion of the multi-focal lens set 106 is gradually changed in the moving direction of the single-focal lens set 104. Specifically, in the moving direction of the single focus lens group 104, the curvature may be gradually changed at all positions of the multi-focus lens group 106, or may be gradually changed at some positions of the multi-focus lens group 106. In this way, it is ensured that the curvatures of at least two positions of the multifocal lens group 106 in the moving direction of the single focal lens group 104 are different.

Therefore, when the driving assembly 108 drives the single-focus lens group 104 to move laterally, the single-focus lens group 104 and the multi-focus lens group 106 can be used in cooperation with different curvature positions, and along with the gradual change of the curvature of the multi-focus lens group 106, the overall curvature of the camera device also changes gradually, so that the whole camera device can realize optical continuous zooming, and further the camera device can meet different camera requirements.

As a possible embodiment, as shown in fig. 1, 3 and 4, the multifocal lens group 106 includes at least a first functional zone 110 and a second functional zone 112; the first functional area 110 and the second functional area 112 are distributed along the moving direction of the single focal lens group 104, and the curvatures of the first functional area 110 and the second functional area 112 are different.

In addition, the curvature of the second functional region 112 is greater than the curvature of the first functional region 110. Thus, as shown in fig. 1, when the single focal lens group 104 is used in cooperation with the first functional region 110, the curvature of the entire image capturing apparatus is small, and the image capturing apparatus can be used for capturing a distant scene; as shown in fig. 3, when the single-focal-lens group 104 is used in combination with the second functional region 112, the curvature of the entire image pickup apparatus is large, and the image pickup apparatus can be used to pick up a near scene. Specifically, as shown in fig. 4, the first functional region 110 is a far region, and the second functional region 112 is a near region.

Therefore, based on the design of the first functional area 110 and the second functional area 112, the camera device can be used for shooting a far scene and a near scene, so that the camera device can at least meet the requirements of two shooting scenes, and further the camera device can replace two camera devices in the related art.

As a possible embodiment, as shown in fig. 2 and 4, a third functional area 114 is further included between the first functional area 110 and the second functional area 112 of the multifocal lens group 106, wherein a curvature of the third functional area 114 is greater than a curvature of the first functional area 110 and less than a curvature of the second functional area 112. In this way, the third functional area 114 can play a role of transition between the first functional area 110 and the second functional area 112, and the purpose of distance conversion of the shooting distance is achieved.

As shown in fig. 2, when the single-focus lens group 104 is used in cooperation with the third functional region 114, the curvature of the entire image pickup apparatus is appropriate (larger than the curvature of the single-focus lens group 104 in cooperation with the first functional region 110, and smaller than the curvature of the single-focus lens group 104 in cooperation with the second functional region 112), and the image pickup apparatus can be used for photographing a middle scene. Specifically, the third functional area 114 is a gradation area.

As a possible embodiment, as shown in fig. 4, the curvature of the third functional region 114 is gradually increased in a direction from the first functional region 110 to the second functional region 112.

Thus, when the driving assembly 108 drives the single-focus lens group 104 to move in the direction from the first functional area 110 to the second functional area 112, the single-focus lens group 104 and the multi-focus lens group 106 can be used in cooperation at different curvature positions, and the curvature of the whole image pickup device gradually increases with the gradual increase of the curvature of the multi-focus lens group 106, so that the change of the shooting distance from far to near is realized. Conversely, when the driving assembly 108 drives the single-focus lens group 104 to move in the direction from the second functional area 112 to the first functional area 110, the curvature of the multi-focus lens group 106 gradually decreases, so that the curvature of the entire image pickup apparatus also gradually decreases, and the shooting distance is changed from near to far.

In addition, in the direction from the first functional area 110 to the second functional area 112, the curvature of the third functional area 114 is gradually increased, so that the surface shapes and curvatures of the first functional area 110 and the third functional area 114 of the multifocal lens group 106 are naturally connected, and the surface shapes and curvatures of the third functional area 114 and the second functional area 112 of the multifocal lens group 106 are naturally connected, so that the surface shape of the whole multifocal lens group 106 is smooth, the light gathering capability of the multifocal lens group 106 can be continuously changed, the continuity of curvature change of the multifocal lens group 106 is ensured, the continuity of zooming of the whole camera is ensured, and the smoothness of distance conversion in the shooting process is ensured.

As a possible implementation, the curvature of the first functional region 110 is constant in the direction from the first functional region 110 to the second functional region 112. Therefore, the focal length of the camera device in the first functional area 110 is a fixed value, which ensures the focusing stability of the camera device in the first functional area 110, thereby ensuring the shooting definition.

Further, the curvature of the first functional region 110 may also be gradually increased in a direction from the first functional region 110 to the second functional region 112. Thus, the positions of the multi-focus lens group 106 with gradually changed curvature are increased, so that the focusing range and the focusing accuracy of the camera are improved, and the overall performance of the camera is improved.

As a possible implementation, the curvature of the second functional region 112 is constant in the direction from the first functional region 110 to the second functional region 112. Therefore, the focal length of the camera device in the second functional area 112 is a fixed value, which ensures the focusing stability of the camera device in the second functional area 112, thereby ensuring the shooting definition.

Further, the curvature of the second functional region 112 may also be gradually increased in the direction from the first functional region 110 to the second functional region 112. Thus, the positions of the multi-focus lens group 106 with gradually changed curvature are increased, so that the focusing range and the focusing accuracy of the camera are improved, and the overall performance of the camera is improved.

As one possible embodiment, as shown in fig. 1, 2 and 3, the single focal lens group 104 includes a mounting member 116 and at least two single focal lenses 118, and the at least two single focal lenses 118 are disposed on the mounting member 116 in the height direction. In this way, the pixels of the imaging device can be increased and the performance of the imaging device can be ensured by using the single focus lens 118 in a superimposed manner in the height direction.

In the embodiment, three single focus lenses 118 are shown in fig. 1, fig. 2 and fig. 3, but it can be understood by those skilled in the art that the number of the single focus lenses 118 can be adjusted according to actual requirements, and when the requirement for the captured image is high, the shooting performance of the image capturing apparatus can be adjusted by appropriately increasing the number of the single focus lenses 118.

As one possible implementation, as shown in fig. 1, 2 and 3, the drive assembly 108 includes a first drive portion 120 and a second drive portion 122. The first driving portion 120 is disposed on the housing 100, the second driving portion 122 is disposed on the single-focus lens group 104, and the single-focus lens group 104 is driven to move laterally above the multi-focus lens group 106 by the cooperation of the first driving portion 120 and the second driving portion 122, so as to achieve zooming of the image capturing apparatus.

In a specific embodiment, as shown in fig. 1, 2 and 3, one of the first driving part 120 and the second driving part 122 may be a magnet, and the other may be a coil. Specifically, the first driving part 120 may be a magnet, and the second driving part 122 may be a coil; the first driving unit 120 may be a coil, and the second driving unit 122 may be a magnet. In this way, the coil may be energized to generate a magnetic field around the coil, and then under the action of the magnetic field, the coil and the magnet generate an interaction force, so that the coil and the magnet approach each other or separate from each other, that is, the first driving portion 120 and the second driving portion 122 approach each other or separate from each other, so that the driving portion may drive the single-focus lens group 104 to move laterally above the multi-focus lens group 106, thereby achieving zooming of the image pickup apparatus.

Further, in the specific embodiment, as shown in fig. 1, fig. 2 and fig. 3, the driving assemblies 108 are disposed at two ends of the single-focus lens group 104, so that the driving assemblies 108 at two ends of the single-focus lens group 104 cooperate with each other to ensure the smoothness and flexibility of movement of the single-focus lens group 104.

As one possible embodiment, as shown in fig. 1, 2 and 3, the photosensitive assembly 102 includes a filter 124, a photosensitive chip 126 and a circuit board 128. The circuit board 128 is disposed at the bottom of the housing 100, the photo chip 126 is disposed at the top of the circuit board 128 and electrically connected to the circuit board 128, and the optical filter 124 is disposed between the circuit board 128 and the multi-focus lens set 106.

Thus, during shooting, light enters from the single-focus lens group 104, passes through the multi-focus lens group 106 and the filter 124, and reaches the photosensitive chip 126. The photosensitive chip 126 has a high requirement on a light source, and has a strong sensing capability on invisible light such as infrared light, and the filter 124 is arranged between the circuit board 128 and the multifocal lens group 106, so that the invisible light such as infrared light in light can be effectively filtered, the influence of the invisible light such as infrared light on imaging is avoided, the phenomenon that the color of an imaging picture is reddish is prevented, meanwhile, the diffraction phenomenon can be avoided, and the imaging reliability of the camera device is ensured.

As one possible embodiment, as shown in fig. 1, 2 and 3, the multifocal lens group 106 includes at least one multifocal lens, and the curvature of at least a portion of the at least one multifocal lens is gradually changed in the moving direction of the single-focal lens group 104. Specifically, when the multi-focal lens set 106 includes two or more multi-focal lenses, the two or more multi-focal lenses are distributed in a butterfly shape between the single-focal lens set 104 and the photosensitive element 102.

Therefore, the image capturing device according to the first aspect of the present invention includes a housing 100, a photosensitive assembly 102, a single-focus lens set 104, a multi-focus lens set 106, and a driving assembly 108, wherein the driving assembly 108 drives the single-focus lens set 104 to move laterally, so that the single-focus lens set 104 and the multi-focus lens set 106 are used in cooperation with each other at different positions with different curvatures, and thus the entire image capturing device can achieve optical continuous zooming. When using in electronic equipment, camera device occupies smallly, can reserve more spaces for other parts, and the inside overall arrangement of the electronic equipment of being convenient for still reduces the trompil quantity of electronic equipment casing 100, strengthens electronic equipment's waterproof dustproof effect, increases electronic equipment holistic leakproofness, reliability and aesthetic property.

Furthermore, by limiting the curvatures of the first functional area 110, the second functional area 112 and the third functional area 114 in the multifocal lens group 106, the continuity of curvature change of the multifocal lens group 106 is ensured, so that the continuity of overall zooming of the image pickup apparatus is ensured, the smoothness of distance conversion in the shooting process is ensured, and the smoothness and flexibility of movement of the single-focus lens group 104 are ensured through the mutual matching of the first driving part 120 and the second driving part 122 in the driving assembly 108, so that the stability of zooming of the image pickup apparatus is ensured, and the reliability of the image pickup apparatus is improved. In addition, the filter 124 can be arranged to filter out useless stray light in the shooting process, so that the definition of the shot image is ensured.

A second aspect of the embodiments of the present application provides an electronic apparatus, which includes the above-mentioned image capturing device, and has all the advantages of the above-mentioned image capturing device, which are not discussed herein one by one.

In addition, the electronic equipment further comprises a body, and the camera device is arranged on the body.

Specifically, be provided with an above-mentioned camera device on the body, have small, the appearance is pleasing to the eye, do benefit to advantages such as waterproof dustproof, and can realize the shooting of two kind at least scenes, satisfy the different demands of making a video recording.

Specifically, the electronic device may be a smartphone, a tablet computer, or other device that can mount a camera device, and is not particularly limited herein.

At present, photographing and video recording have become important requirements of people, so that the requirements of people on the functions and the performance of a camera device are higher and higher, and more requirements are also required on the functions of electronic equipment. In order to achieve the best shooting effect in different scenes and meet the requirements of people on shooting, the prior art generally adopts a method of increasing the number of the cameras or using a telescopic camera. However, too many designs of the image capturing device may occupy more internal space of the electronic device and may affect the appearance of the electronic device; electronic equipment using a retractable image pickup device similar to a digital camera has not become mainstream due to the defects of large thickness, weak waterproof and dustproof performance, exposure of the image pickup device, and the like.

Specifically, among the correlation technique, satisfy the mode of people to the shooting demand of different scenes through setting up a plurality of camera devices, can occupy the more inner space of electronic equipment, lead to electronic equipment to become bigger and bigger, inside overall arrangement is more difficult, and simultaneously, more holes need be seted up on electronic equipment to many camera device's design, have reduced electronic equipment's leakproofness, are unfavorable for electronic equipment's waterproof dustproof, still can make electronic equipment's outward appearance pleasing to the eye. And satisfy the mode of people to the shooting demand of different scenes through using telescopic camera device, it is higher to the requirement in vertical space, can increase electronic equipment's thickness, moreover, because flexible height, this type of camera device often can expose outside electronic equipment's casing 100, is unfavorable for waterproof dustproof.

As shown in fig. 1, 2 and 3, the image pickup apparatus of the present application can realize optical continuous zooming by moving the single-focus lens group 104 in a transverse direction, has functions of different types of image pickup apparatuses in the related art, can replace different types of image pickup apparatuses in the related art, and has advantages of small size, low height, and the like. Moreover, when the camera device provided by the application is applied to the electronic equipment, the effect that one camera device replaces a plurality of conventional camera devices can be achieved, more space can be reserved for other components in the electronic equipment, meanwhile, the number of holes formed in the electronic equipment can be reduced, and the sealing performance and the reliability of the electronic equipment are improved. Furthermore, because the action of zooming is horizontal action for camera device can place in electronic equipment's casing 100 is inside, and then makes electronic equipment show better in appearance wholeness, also makes this application camera device compare in telescopic camera device simultaneously, has better waterproof dustproof performance and reliability.

Specifically, as shown in fig. 1, 2 and 3, the image pickup apparatus proposed by the present application uses a plurality of single focal lenses 118 vertically stacked to form a single focal lens group 104 as an upper half of the image pickup apparatus, and uses a multi focal lens group 106 as a lower half of the image pickup apparatus. When the zoom lens is used, the driving device drives the single-focal-lens group 104 which is the upper half part of the image pickup device, so that the single-focal-lens group 104 of the upper half part of the image pickup device and the multi-focal-lens group 106 of the lower half part of the image pickup device are in different relative positions, the whole image pickup device can have different curvatures, and the optical continuous zooming of the image pickup device is realized.

Specifically, as shown in fig. 4, the multifocal lens group 106 of the imaging device of the present application is a progressive multifocal lens group, and includes a first functional area 110, a second functional area 112, and a third functional area 114, where the first functional area 110 is located at an upper portion of the progressive multifocal lens group, the second functional area 112 is located below the progressive multifocal lens group, and the third functional area 114 is located in a transition region between the first functional area 110 and the second functional area 112.

The curvature of the second functional region 112 is greater than the curvature of the first functional region 110, and the curvature of the third functional region 114 is greater than the curvature of the first functional region 110 and less than the curvature of the second functional region 112. That is, the first functional area 110 is used for capturing a far scene and is a far area, the second functional area 112 is used for capturing a near scene and is a near area, and the third functional area 114 is a transition area and plays a role of transition. The curvatures of the third functional area 114 and the progressive area are gradually changed, so that the natural connection between the surface types and the powers of the first functional area 110 and the second functional area 112 of the multifocal lens set 106 can be realized.

It should be noted that, as shown in fig. 4, the progressive addition lens set further includes a fourth functional area 130, which is an astigmatic area, where the image formed in the area is deformed, and the farther from the central area of the area, the more obvious the image quality deformation is, therefore, the area should be avoided as much as possible during the use of the image capturing apparatus.

Therefore, this application full play the special performance of multifocal lens group gradually for single camera device can realize optics and zoom in succession, when camera device used electronic equipment on, reducible electronic equipment's trompil figure, so that electronic equipment possess better dustproof and waterproof performance, the outward appearance is more pleasing to the eye, and simultaneously, camera device occupies the volume and reduces, has reserved more stack space for other components and parts in the electronic equipment.
