The image pickup apparatus and the electronic device provided according to the embodiments of the present application are further described below with reference to the accompanying drawings.
According to an embodiment of the present application, there is provided an image pickup apparatus that can be applied to various forms of electronic devices to provide the electronic devices with functions of photographing, image pickup, and the like.
Referring to fig. 1 to 3, the image capturing device according to the embodiment of the present application includes a first lens assembly 1 and a second lens assembly 2 stacked together, and the second lens assembly 2 is located at one side of the first lens assembly 1. The first lens assembly 1 comprises a first lens. The second lens assembly 2 includes a first lens barrel 23, a second lens 21 and a third lens 22 disposed in the first lens barrel 23, wherein the first lens, the second lens 21 and the third lens 22 are stacked in a first direction, and the third lens 22 is sandwiched between the first lens and the second lens 21. The second lens 21 is fixedly connected with the first portion 231 of the first lens barrel 23, and the third lens 22 is fixedly connected with the second portion 232 of the first lens barrel 23; the light incident side of the second lens 21 is provided with a first compensation structure 213, the light emergent side of the third lens 22 is provided with a second compensation structure 223, the first compensation structure 213 is matched with the second compensation structure 223, and the relative positions of the first compensation structure 213 and the second compensation structure 223 are adjusted to compensate the offset of the focal length of the image capturing device.
For the image pickup device, if an error occurs in the assembly process, or the temperature around the image pickup device changes in use or the image pickup device is collided, the image pickup device may have a focus offset phenomenon, which may cause a decrease in resolution and a blurred imaging picture.
According to the above embodiment of the present application, referring to fig. 1, the image capturing device includes, for example, a first lens assembly 1 and a second lens assembly 2. The second lens component 2 is a newly added device in the whole image capturing apparatus, and is located at one side of the first lens component 1. The second lens assembly 2 includes, for example, two lenses, the second lens 21 and the third lens 22, respectively, and a first compensation structure 213 is disposed on the light incident side of the second lens 21, and a second compensation structure 223 is disposed on the light emergent side of the third lens 22, so that the second lens 21 and the third lens 22 have a function of changing focal length due to the respective compensation structures, and a certain compensation effect can be achieved on the incident light 01 by adjusting the relative positional relationship between the first compensation structure 213 and the second compensation structure 223, see fig. 2 and 3, and the compensation effect can be used for correcting the offset of focal length generated by the image capturing device, so as to avoid the situation of reduced resolution of the image capturing device.
Wherein the change of the relative positions of the first compensation structure 213 and the second compensation structure 223 can be achieved by controlling the relative movement of the second lens 21 and the third lens 22.
It should be noted that there are many ways to implement the relative movement between the second lens 21 and the third lens 22, and the present application is not limited in detail herein.
According to the above-described embodiment of the present application, referring to fig. 1, the first lens 11, the second lens 21, and the third lens 22 are stacked in a first direction, wherein the first direction is referred to as r1 shown in fig. 1, and the first direction r1 refers to an axial direction of the first barrel 23.
According to some examples of the present application, referring to fig. 2 and 3, the first portion 231 and the second portion 232 are respectively located at opposite sides of the first barrel 23, and the second lens 21 and the third lens 22 are moved in opposite directions, so that the first compensation structure 213 and the second compensation structure 223 are moved in opposite directions to change an imaging focal length of the incident light 01.
According to the above example, for the second lens assembly 2, the mounting positions of the second lens 21 and the third lens 22 are opposite in the first lens barrel 23, on the basis of this, by designing to move the second lens 21 and the third lens 22 reversely, the relative positions of the first compensation structure 213 and the second compensation structure 223 can be changed, and the first compensation structure 213 and the second compensation structure 223 cooperate to compensate the incident light 01, so that the focal length offset of the image capturing device can be corrected, so as to ensure that the image capturing device has better imaging quality.
In practice, there are various reasons for the offset of the focal length of the image pickup apparatus. For example, there is an error in assembling the image pickup apparatus, a change in temperature around the image pickup apparatus, or an impact on the image pickup apparatus during use, or the like, which causes a shift in focal length. By the way provided in the above example, the shift of the focal length of the image pickup apparatus can be corrected.
It should be noted that the manner of the relative movement of the second lens 21 and the third lens 22 according to the shape and the relative position of the first compensation structure 213 and the second compensation structure 223 in the present application may be designed, including but not limited to the reverse movement in the above example.
According to some examples of the present application, referring to fig. 1 and 2, the first compensation structure 213 and the second compensation structure 223 are symmetrical, and the first lens barrel 23 deforms due to temperature change and drives the second lens 21 and the third lens 22 to move reversely, so that the focal length of the image capturing device is kept unchanged before and after the temperature change.
Specifically, the image pickup device is applied to an electronic apparatus, for example, after the electronic apparatus is used for a long time, the heat generated by a processing chip in the electronic apparatus may cause a temperature increase around the image pickup device, at this time, the first lens barrel 23 may undergo thermal expansion deformation, so as to pull/drive the second lens 21 connected to the first portion 231 thereof and the third lens 22 connected to the second portion 232 thereof to move reversely along a radial direction of the first lens barrel 23, and thus, an imaging focal length of the incident light 01 may be changed based on the shape matching of the first compensation structure 213 and the second compensation structure 223, thereby achieving a zoom effect. This makes it possible to compensate for the focal length change of the camera device, for example, due to a temperature increase, so that the focal length of the camera device remains unchanged before and after the temperature change, see fig. 2 and 3.
Referring to fig. 1, the incident light 01 enters the second lens component 2 along the Z-direction, passes through the second lens component 2, and then enters the first lens component 1. When the incident light 01 passes through the second lens component 2, if the ambient temperature increases, the second lens 21 and the third lens 22 can move reversely along the XY direction under control, and the focusing function is realized by the self-contained compensation structures of the second lens and the third lens respectively.
According to the scheme provided by the example, the problem of temperature drift of the image pickup device can be solved, and the image pickup device can still guarantee high-definition imaging even in a temperature-rising environment. Wherein, through the focusing function of the second lens component 2, the focal length of the image pickup device can be ensured to be unchanged before and after the temperature change.
For example, referring to fig. 4 and 5, the first lens barrel 23 is expanded and deformed in XY direction due to temperature change, and simultaneously drives the second lens 21 and the third lens 22 to move reversely, so as to ensure that the focal length of the image pickup device remains unchanged before and after the temperature change. After the second lens 21 and the third lens 22 move, they are central symmetrical with respect to a point a in the first lens barrel 23, wherein the point a is located, for example, on a central line of the first lens barrel 23 along an axial direction thereof.
In some examples of the application, referring to fig. 3, the first compensating structure 213 includes a first protrusion 214 and a first recess 215 connected, and the second compensating structure 223 includes a second protrusion 224 and a second recess 225 connected; the first protrusion 214 is adjacent to the first portion 231, the first recess 215 is adjacent to the second portion 232, the second protrusion 224 is adjacent to the second portion 232, and the second recess 225 is adjacent to the first portion 231.
According to the above example, the second lens 21 and the third lens 22 are respectively provided with compensation structures, each of which includes a convex portion and a concave portion, and the convex portion is located between the connecting portion and the concave portion of the lenses. The compensation structure may make the second lens 21 and the third lens 22 have a specific surface shape.
The second lens 21 and the third lens 23 are respectively provided with a compensation structure, and the compensation structure enables the surface shape of the lens to comprise a convex part and a concave part which are connected, wherein the convex part forms a thicker part on the lens, and the concave part forms a thinner part on the lens. The surface design uses a free-form surface system described by a three-order XY polynomial, the focal length of which is determined by the lateral relative displacement of the second lens 21 and the third lens 22. When the second lens assembly is in operation, at least one of the lenses is moved in a direction perpendicular to the optical axis, effecting a change in focal length, see fig. 3.
In some examples of the application, referring to fig. 4 and 5, the second lens 21 and the third lens 22 are alvarez lenses; and/or the end of the second lens 21 away from the first portion 231 is a free end, and the end of the third lens 22 away from the first portion 231 is a free end.
According to the above example, both lenses of the second lens assembly 2 are Alvarez lenses (Alvarez lens), at which time the second lens assembly 2 forms an Alvarez lens (Alvarez lens) in the entire image pickup apparatus, so that the formed image pickup apparatus has optical performance of zooming.
In some examples of the present application, referring to fig. 4 and 5, the first portion 231 and the second portion 232 are located on opposite sides of the first lens barrel 23, the inner wall of the lens barrel 23 is provided with a first guiding structure 3, the first guiding structure 3 is disposed opposite to the first portion 231, and the first guiding structure 3 and the second portion 232 are disposed along the first direction; the first guiding structure 3 is used for guiding the movement of the second lens 21, so that the first compensating structure 213 moves relative to the second compensating structure 223 along a second direction, and the second direction is perpendicular to the first direction.
According to the above example, based on the arrangement position of the first guide structure 3 on the inner wall of the lens barrel 23, the first guide structure 3 can support the free end of the second lens 21, and can ensure that the moving direction of the second lens 21 is always perpendicular to the first direction, which is the axial direction of the first lens barrel 23, when moving. Since the movement of the second lens 21 is to change the focal length of the image capturing device, if the second lens 21 is not perpendicular to the first direction during the movement, but a certain skew is generated, the focal length may be not compensated. The design of the first guiding structure 3 is beneficial to improving the accuracy of focal length adjustment.
The second direction r2 is, for example, a radial direction of the first lens barrel 23, see fig. 2.
In some examples of the application, referring to fig. 2, 4 and 5, the second lens 21 includes a first side 211 and a second side 212 facing away from each other, the first side 211 is connected to the first portion 231, and the second side 212 extends into the first guiding structure 3; a first limiting member 31 is further disposed in the first guiding structure 3, so as to limit the second lens 21 along the second direction.
In some examples of the application, referring to fig. 2, 4 and 5, the first guiding structure 3 has a first guiding channel 32, the second lens 21 includes a first side 211 and a second side 212 facing away from each other, the first side 211 is connected to the first portion 231, and the second side 212 protrudes into the first guiding structure 3; the second side 212 is provided with a second limiting member, and the second limiting member abuts against the inner wall of the first guiding channel 32 along the first direction to cooperate with the first guiding structure 3 to guide the second lens 21.
According to the above two examples, it is ensured that the second lens 21 is always perpendicular to the first direction when moving in the first barrel 23, and that no deflection occurs in the second direction due to gravity or the like even in long-term use. Moreover, it can be used to limit the moving distance of the second lens 21, so as to ensure that the focal length of the image capturing device is changed within the required range.
In some examples of the present application, referring to fig. 4 and 5, the inner wall of the lens barrel 23 is further provided with a second guiding structure 4, the second guiding structure 4 is disposed opposite to the second portion 232, and the second guiding structure 4 and the first portion 231 are disposed along the first direction; the second guiding structure 4 is used for guiding the movement of the third lens 22, so that the second compensating structure 223 moves along the second direction relative to the first compensating structure 213.
In order to control the movement of the third lens 22, a second guiding structure 4 is also arranged in the first lens barrel 23. The second guide structure 4 is identical in structure and function to the first guide structure 3.
In the first lens barrel 23, based on the arrangement of the first guide structure 3 and the second guide structure 4, the moving directions of the second lens 21 and the third lens 22 in the relative moving process are perpendicular to the first direction, so that the accuracy of the compensation of the focal length can be ensured.
