Description

CAMERA ASSEMBLY AND ELECTRICAL DEVICE

TECHNICAL FIELD

The present disclosure relates to a camera assembly and an electrical device.

BACKGROUND

Electrical devices such as smartphones and tablet terminals are widely used in our daily life. Nowadays, many of the electrical devices are equipped with a camera assembly for capturing images. Some of the electrical devices are portable and are thus easy to carry. Therefore, a user of the electrical device can easily take a picture of an object by using the camera assembly of the electrical device anytime, anywhere.

The portability of the electrical device is very important for the user and therefore the electrical devices should be as thin as possible. If the height of the camera assembly is large, the camera assembly will project outside the surface of the electrical device. Therefore, the height of the camera assembly should also be as small as possible. On the other hand, from the viewpoint of improving optical performance, a flange back distance should be sufficiently long because a proper focal length is necessary for a large size image sensor.

Here, the telephoto lens has a long lens overall length in order to secure the focal length. Therefore, it is difficult to mount this telephoto lens on a smartphone.

As a mounting method of this telephoto lens, there is a periscope type in which a light beam is bent at 90 degrees by using a prism. With this method, it is difficult to adjust the optical axis of the prism. For this reason, a decrease in the yield of smartphones and an increase in manufacturing costs of smartphones have become problems.

SUMMARY

The present disclosure aims to solve at least one of the technical problems mentioned above. Accordingly, the present disclosure needs to provide a camera assembly and an electrical device.

In accordance with the present disclosure, a camera assembly includes:

a body configured to have a first side, a second side opposite to the first side, and a storage portion having an opening provided in the first side; and

a camera unit configured to be stored in the storage portion, to rotate around a rotation shaft provided in the storage portion, and to include a lens barrel and an image sensor, and

wherein, when the camera unit is not used for shooting, the camera unit is arranged at a storage position in the storage portion so that an optical axis of the lens barrel is sandwiched between the first side and the second side, and

wherein, when the camera unit is used for shooting, the camera unit is arranged at a shooting position where an angle of a direction of the optical axis of the lens barrel with respect to the first side is a shooting angle, by rotating the camera unit around a rotation shaft from the storage position.

In accordance with the present disclosure, an electrical device includes:

a camera assembly comprising:

a controller configured to control the camera assembly,

The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to the drawings are explanatory and aim to illustrate the present disclosure, but shall not be construed to limit the present disclosure.

FIG. 1A is a plan view of a first side of an electrical device 10 in a shooting position according to an embodiment of the present disclosure, FIG. 1B is a plan view of a first side of an electrical device 10 in a storage position according to an embodiment of the present disclosure, and FIG. 2 is a plan view of a second side of the electrical device 10 according to the embodiment of the present disclosure. The first side may be referred to as a back side of the electrical device 10 whereas the second side may be referred to as a front side of the electrical device 10.

As shown in FIG. 1A, FIG1B, and FIG. 2, the electrical device 10 may include a display 20 and a camera assembly 30.

In the present embodiment, the camera assembly 30 includes a body M, a main camera (a camera unit) U, a camera cover C, and a sub camera 36.

As shown in FIG. 1A, FIG1B, and FIG. 2, the body M has a first side M1 and a second side M1 on the opposite side of the first side M1, and the first side M1 is provided with a storage portion (a storage unit) S having an opening M1O.

As shown in FIG. 1A and FIG1B, the camera cover C is provided on the first side M1 of the body M to protect the camera unit U. The camera cover C is slidable along a rail L provided on the body M in a direction parallel to the first side M1 of the body M.

For example, as shown FIG. 1A, when the camera unit U is used for shooting, the camera unit U is arranged at the shooting position. Furthermore, when the camera unit U is used for shooting, the camera cover C is positioned so as not to cover the opening M1O of the storage portion S, with the camera unit U placed in the shooting position.

On the other hand, as shown FIG. 1B, when the camera unit U is not used for photographing, the camera unit U is arranged at a storage position in the storage position S by rotating. Furthermore, when the camera unit U is not used for shooting, the camera cover C is positioned so as to cover the opening M1O of the storage portion S, with the camera unit U arranged at the storage position in the storage portion S.

Here, the camera unit U in the shooting position (FIG. 1A) can capture an image in the first side of the electrical device 10 and the sub camera 36 (FIG. 2) can capture an image in the second side of the electrical device 10. Therefore, the camera unit U is so-called out-cameras whereas the sub camera 36 is a so-called in-camera. As an example, the electrical device 10 can be a mobile phone, a tablet computer, a personal digital assistant, and so on.

Each of the camera unit (main camera) U and the sub camera 36 has an imaging sensor which converts a light which has passed a color filter to an electrical signal. A signal value of the electrical signal depends on an amount of the light which has passed the color filter.

Although the electrical device 10 according to the present embodiment has three cameras, the electrical device 10 may have less than three cameras or more than three cameras. For example, the electrical device 10 may have two, four, five, and so on, cameras.

Especially, in the present embodiment, the camera unit (the main camera) U is, for example, a telephoto camera.

Each of the camera unit (the main camera) U and the sub camera 36 has an AF (Autofocus) function and an OIS (Optical Image Stabilization) function.

Here, FIG. 3 is a block diagram of the electrical device 10 according to the present embodiment. As shown in FIG. 3, in addition to the display 20 and the camera assembly 30, the electrical device 10 may include a main processor 40, an image signal processor 42, a memory 44, a power supply circuit 46 and a communication circuit 48. The display 20, the camera assembly 30, the main processor 40, the image signal processor 42, the memory 44, the power supply circuit 46 and the communication circuit 48 are connected with each other via a bus 50.

The main processor 40 executes one or more program instructions stored in the memory 44. The main processor 40 implements various applications and data processing of the electrical device 10 by executing the program instructions. The main processor 40 may be one or more computer processors. The main processor 40 is not limited to one CPU core, but it may have a plurality of CPU cores. The main processor 40 may be a main CPU of the electrical device 10, an image processing unit (IPU) or a DSP provided with the camera assembly 30.

That is, the main processor 40 constitutes a controller of the electrical device 10 in the present embodiment.

The image signal processor 42 controls the camera assembly 30 and processes various kinds of image data captured by the camera assembly 30 to generate a target image data. For example, the image signal processor 42 can apply a demosaicing process, a noise reduction process, an auto exposure process, an auto focus process, an auto white balance process, a high dynamic range process and so on, to the image data captured by the camera assembly 30.

In the present embodiment, the main processor 40 and the image signal processor 42 collaborate with each other to generate a target image data of the object captured by the camera assembly 30. That is, the main processor 40 and the image signal processor 42 are configured to capture the image of the object by means of the camera assembly 30 and apply various kinds of image processing to the captured image data.

The memory 44 stores program instructions to be executed by the main processor 40, and various kinds of data. For example, data of the captured image are also stored in the memory 44.

The memory 44 may include a high-speed RAM memory, and/or a non-volatile memory such as a flash memory and a magnetic disk memory. That is, the memory 44 may include a non-transitory computer readable medium in which the program instructions are stored.

The power supply circuit 46 may have a battery such as a lithium-ion rechargeable battery and a battery management unit (BMU) for managing the battery.

The communication circuit 48 is configured to receive and transmit data to communicate with base stations of the telecommunication network system, the Internet or other devices via wireless communication. The wireless communication may adopt any communication standard or protocol, including but not limited to GSM (Global System for Mobile communication) , CDMA (Code Division Multiple Access) , LTE (Long Term Evolution) , LTE-Advanced, 5th generation (5G) . The communication circuit 48 may include an antenna and an RF (radio frequency) circuit.

Next, a configuration focusing on the camera unit U of the camera assembly 30 having the configuration as described above will be described in detail.

Here, FIG. 4A is an oblique perspective view of the first side of the electrical device in the shooting position according to the embodiment of the present disclosure. FIG. 4B is an oblique perspective view of the first side of the electrical device in the storage position according to the embodiment of the present disclosure. FIG. 5A is a cross section view of the electrical device in the shooting position according to the embodiment of the present disclosure. FIG. 5B is a cross section view of the electrical device in the storage position according to the embodiment of the present disclosure.

In the present embodiment, for example, as shown in FIGS. 4A, 4B, 5A and 5B, the camera unit U is housed in the storage portion S, and the camera unit U is rotatable around a rotation shaft R provided in the storage portion S. The rotation shaft R is connected to the second end U2 of the camera unit U where the image sensor 68 is located.

For example, as shown in FIG. 4A and FIG. 5A, when the camera unit U is used for shooting, the camera unit U is arranged at a shooting position where the angle of the lens barrel 64 in the direction of the optical axis AX with respect to the first side M1 is the shooting angle θZ, by rotating the camera unit U around the rotation shaft R from the storage position.

In particular, in this embodiment, as shown in FIG. 4A and FIG. 5A, when the camera unit U is arranged in the shooting position, the first end U1 of the camera unit U, where the lens barrel 64 is located, projects outward from the first side M1 of the body M, through the opening M1O.

It is noted that when the camera unit U is used for shooting, the camera cover C is positioned so as not to cover the opening M1O of the storage portion S, in a state where the camera unit U is arranged at the shooting position,

The shooting angle θZ is 90 degrees in the examples of FIGS. 4A and 5A, for example.

In particular, the length of the camera unit U in the direction of the optical axis AX of the camera unit U is longer than the distance (the thickness) between the first side M1 and the second side M2 of the body M.

As a result, when the camera unit U is used for shooting, the electrical device 10 can be set in a state in which a telephoto camera (the camera unit U) that requires a predetermined flange back distance can be photographed.

On the other hand, as shown in FIG. 4B and FIG. 5B, when the camera unit U is not used for shooting, the camera unit U is arranged at a storage position in the storage portion S so that the optical axis of the lens barrel 64 is sandwiched between the first side M1 and the second side M1.

In particular, in this embodiment, as shown in FIG. 4B and FIG. 5B, when the camera unit U is not used for shooting, the camera unit U is arranged at the storage position so that the direction of the optical axis AX of the lens barrel 64 is parallel to the first side M1. Furthermore, when the camera unit U is arranged in the storage position, the first end U1 of the camera unit U is located in the storage portion S.

Furthermore, when the camera unit U is not used for shooting, the camera cover C is positioned so as to cover the opening M1O of the storage portion S, in a state where the camera unit U is arranged at the storage position in the storage portion S.

As a result, when the camera unit U is not used for shooting, the electrical device 10 can house a telephoto camera (the camera unit U) , that requires a predetermined flange back distance, inside the body M, regardless of the thickness of the body M.

That is, the electrical device 10 can mount a telephoto camera (the camera unit U) that requires a predetermined flange back distance without using a prism.

In the examples of FIG. 4A and FIG. 5A, the shooting angle θZ is one, but a plurality of shooting angles may be set. In this case, for example, the camera unit U rotates about the rotation shaft R, so that the shooting angle is changed stepwise.

It is noted that, as shown in FIG. 5A and FIG. 5B, the lens unit U has the lens barrel 64 which includes one or more optical lenses. An optical axis AX of each of the optical lenses is aligned. That is, the optical axes AX of the optical lenses are straightly aligned. In the present embodiment, the lens barrel 64 is composed of one or more convex lenses and one or more concave lenses. In other words, the optical lenses are also referred to as a combination lens.

Furthermore, as shown in FIG. 5A and FIG. 5B, in the present embodiment, the lens unit U has an image sensor 68. The image sensor 68 captures an image of an object through the lens barrel 64 of the lens unit U. That is, the image of the object is formed on the image sensor 68. The image sensor 68 converts the intensity of light passing through the optical lenses to electrical signals which are sent to, for example, the main processor 40 and/or the image signal processor 42.

In the present embodiment, for example, the image sensor 68 is a solid state imaging device such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor, a CCD (Charge-Coupled Device) image sensor and so on.

Here, a flange back distance can be defined as a distance between the image sensor 68 and a first optical lens which is the closest one to the image sensor 68 among the optical lenses.

Next, an example of a structure focusing on the waterproof mechanism of the camera assembly 30 having the above-described configuration will be described.

FIG. 6 is a side perspective view of the electrical device in the storage position according to the embodiment of the present disclosure. FIG. 7 is a cross section view of the electrical device along the rotation shaft according to the embodiment of the present disclosure.

AS shown in FIG. 6 and FIG. 7, the rotation shaft R has a hollow internal RA. The wiring connecting the wiring in the camera unit U and the wiring in the body M may be passed through, in the hollow inner RA of the rotation shaft R.

Furthermore, in the storage section S, the rotation shaft R is fixed to the camera unit U. The rotation shaft R is inserted into a through hole MR that is formed in the inner wall of the storage portion S and penetrating the inside of the body M.

AS shown in FIG. 6 and FIG. 7, the camera assembly 30 further comprises an O-ring Or. The O-ring Or is arranged between the camera unit U and the inner wall, with the rotation shaft R inserted in the O-ring Or. This O-ring Or is waterproofed from the storage portion S to the inside of the body M.

As a result, the waterproofness of the camera assembly 30 can be improved while constructing the wiring between the camera unit U and the inside of the body M.

As mentioned above, the camera assembly includes: a body configured to have a first side, a second side opposite to the first side, and a storage portion having an opening provided in the first side; and a camera unit configured to be stored in the storage portion, to rotate around a rotation shaft provided in the storage portion, and to include a lens barrel and an image sensor. When the camera unit is not used for shooting, the camera unit is arranged at a storage position in the storage portion so that an optical axis of the lens barrel is sandwiched between the first side and the second side. When the camera unit is used for shooting, the camera unit is arranged at a shooting position where an angle of a direction of the optical axis of the lens barrel with respect to the first side is a shooting angle, by rotating the camera unit around a rotation shaft from the storage position.

As a result, the electrical device of the present invention can be equipped with a telephoto camera that requires a predetermined flange back distance, without using a prism, at general difficulty.

Therefore, the yield of the electrical device can be improved and the manufacturing cost of the electrical device can be reduced.
