The periscopic camera module and the terminal device provided in the embodiments of the present application will be described in detail below. It should be understood that the specific features in the embodiments and examples of the present application are detailed description of the technical solutions in the embodiments of the present application, and are not limited to the technical solutions in the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.

In a first aspect, an embodiment of the present application provides a periscopic camera module. As shown in fig. 1, the periscopic camera module includes: the image sensor includes a first light adjusting member 110, an optical lens group 120, a second light adjusting member 130 formed with an infrared filter, and an image sensor 140 disposed in parallel to an optical axis direction of the optical lens group 120. The first light adjusting member 110 and the second light adjusting member 130 are both optical members having a light path turning function, such as a reflective prism or a reflective mirror, and an infrared filter is formed in the second light adjusting member 130, so that the light path turning function and the infrared light filtering function are integrated in the second light adjusting member 130.

The straight line with arrows in fig. 1 is used to illustrate the propagation path of light in the periscopic camera module. Light incident from the outside is reflected to the optical lens group 120 through the first light adjusting component 110, is converged to the second light adjusting component 130 through the optical lens group 120, and infrared light in the light is filtered by the second light adjusting component 130 and reflected to the image sensor 140 for imaging.

The second dimming component 130 formed with the infrared filter film is arranged between the optical lens group 120 and the image sensor 140, and the optical path turning function and the infrared light filtering function are realized at the same time, so that on one hand, the image sensor 140 can be arranged in parallel to the optical axis direction of the optical lens group 120, the limitation of the size of the image sensor 140 on the height size of the camera film group is reduced, and the high pixel requirement of the image sensor 140 is met, and meanwhile, the periscopic camera module is ensured to be thinner; on the other hand, compared with the case where the optical filter is separately mounted on the photosensitive side of the image sensor 140, the size and weight of the entire camera module can be further reduced, so as to meet the requirement of lightness and thinness of the terminal device to which the periscopic camera module is applied.

Specifically, the optical lens group 120 is used to focus the incident light and finally image the light onto the image sensor 140, and the optical path design may be specifically performed according to actual needs.

The second dimming part 130 is used to filter infrared light from the light incident from the optical lens group 120 and turn the light by 90 degrees, so that the light is incident to the photosensitive side of the image sensor 140 to be imaged. It is understood that, in the second dimming member 130, an infrared filter is disposed on the light transmission path to filter infrared light in the light passing through the second dimming member 130. For example, an infrared filter may be formed on one or more surfaces of the reflective member by coating, so as to obtain the second dimming member 130.

The second light adjusting member 130 may have various embodiments, and the embodiments of the present disclosure mainly illustrate the following three configurations, and in the specific implementation process, other applicable configurations may be adopted, which is not limited herein.

First, as shown in fig. 1, the second dimming member 130 may include an infrared filter 132, a transparent substrate 131, and a reflective film 133, which are stacked. The transparent substrate 131 may be made of a substrate material with a high transmittance, such as glass, the infrared filter 132 may be formed on a first surface of the transparent substrate 131, and the reflective film 133 is formed on a second surface of the transparent substrate 131 opposite to the first surface. That is, the infrared filter film is coated on the first surface of the transparent substrate 131 by a coating method, and the reflective film is coated on the second surface. At this time, the light incident on the second light adjusting member 130 from the optical lens group 120 passes through the infrared filter 132, then passes through the transparent substrate 131, and is reflected by the reflective film 133 to the image sensor 140.

Second, the second dimming member 130 may include a substrate, a reflective film, and an infrared filter film, which are stacked. That is, the reflective film is first coated on the surface of the substrate, and then the infrared filter is formed on the surface of the reflective film. At this time, the light entering the second light adjusting member 130 from the optical lens assembly 120 passes through the infrared filter to filter the infrared light in the light, and then is reflected to the image sensor 140 by the reflective film.

It can be understood that the light path turning can be sufficiently realized by the reflector formed by the substrate and the reflective film, and stray light brought to the camera module by insufficient light turning is avoided.

Third, as shown in fig. 2, the second dimming member 130 may include a first reflection prism 134 and an infrared filter 135 formed on the first target surface of the first reflection prism 134. It can be understood that the reflection prism is a prism having a light turning function, and is generally a right-angle prism, and includes a first right-angle surface, a second right-angle surface and a reflection surface, and light incident from any one of the right-angle surfaces is totally reflected on the reflection surface to realize the turning of the light.

The first target surface may include a first right-angle surface and/or a second right-angle surface of the first reflection prism 134. For example, the first right-angle surface and the second right-angle surface of the first reflection prism 134 may be formed with the infrared filter 135. At this time, light entering the first reflection prism 134 from the optical lens group 120 enters the reflection surface after being filtered by the infrared light of the infrared filter 135 formed on the first right-angle surface, is reflected by the reflection surface to the second right-angle surface, and exits to the photosensitive side of the image sensor 140 after being filtered by the infrared light of the infrared filter 135 formed on the second right-angle surface again. Thus, the infrared light in the light can be effectively filtered through the infrared light filtering treatment twice.

The first light adjusting part 110 is used to turn the externally incident light by 90 degrees, so that the light is incident to the optical lens group 120. For example, the first dimming member 110 may employ a mirror or a reflective prism.

In an alternative embodiment, in order to further enhance the infrared light filtering effect and reduce the system stray light, as shown in fig. 3, the first light adjusting member 110 may include a second reflecting prism 111 and an infrared filter 112 formed on the second target surface of the second reflecting prism 111, so that the first light adjusting member 110 also integrates the light path turning function and the infrared light filtering function. Thus, the infrared light in the light can be filtered more effectively through the dual infrared filtering function of the first dimming component 110 and the second dimming component 130.

Wherein the second target surface may comprise the first right-angled surface and/or the second right-angled surface of the second reflective prism 111.

For example, the infrared filter 112 is formed on the first right-angle surface of the second reflection prism 111. At this time, light incident on the second reflecting prism 111 from the outside is subjected to infrared light filtering processing by the infrared filter 112 formed on the first rectangular surface, enters the reflecting surface, is reflected by the reflecting surface, and then exits from the second rectangular surface to the optical lens group 120.

In specific implementation, the first reflecting prism 134 and the second reflecting prism 111 may be made of optical glass material of H-ZF3 (refractive index 1.7173), or may be made of other high refractive index materials such as optical glass material of H-ZF4, H-ZF5 or H-ZF 6. It can be understood that the higher the refractive index of the prism material, the smaller the size of the reflecting prism, but the higher the refractive index, the higher the material cost, and therefore, the material cost is determined according to the requirement of the light path design in the practical application scenario.

In a second aspect, the embodiment of the present application further provides a terminal device, as shown in fig. 4, the terminal device 40 includes a display screen 200 and a periscopic camera module 100, and a photosensitive side of an image sensor 140 in the periscopic camera module 100 is disposed in parallel to the display screen 200. It is understood that the x-axis direction shown in fig. 4 is the thickness direction of the terminal apparatus 40, i.e., the height direction of the periscopic camera module 100 mounted in the terminal apparatus 40, and the y-axis direction is the length direction of the terminal apparatus 40. The detailed structure of the periscopic camera module 100 can refer to the description of the first aspect, and is not described herein again.

Of course, besides the display screen 200 and the periscopic camera module 100, the terminal device 40 further includes other structures, such as a housing, a processor, a memory, and the like, and details of implementation can refer to related technologies related to the terminal device 40, which are not described in detail herein. For example, the terminal device 40 may be an electronic device with a camera function, such as a mobile phone, a tablet computer, and a notebook computer.

Because the periscopic camera module that above-mentioned first aspect provided can guarantee that whole camera module height dimension is lower under the condition that adopts high pixel image sensor, and thickness is thinner promptly, consequently, is favorable to making the terminal equipment who installs this camera module realize frivolousization when having higher image quality.

It will be appreciated by those skilled in the art that layers, regions, etc. of the desired shape may be formed by various technical means.
