Fig. 1b is a top view of an image capture device shown according to an exemplary embodiment of the present disclosure. Fig. 1c is a side view of an image capture device shown according to an exemplary embodiment of the present disclosure.

As shown in fig. 5, the image capturing apparatus 100 provided in the first aspect of the embodiment of the present disclosure may be applied to a mobile terminal 200, and perform a photographing or image capturing function of the mobile terminal 200. The mobile terminal 200 may be a mobile phone, a tablet computer, a notebook computer, a camera, a wearable device such as a watch, a smart band, etc. In addition, the image capturing apparatus 100 can also be used as a stand-alone device, such as a video camera, for taking or recording images of an object to be captured.

Taking a mobile phone as an example, the mobile terminal 200 includes a housing 210 and a display 220 installed in front of the housing 210. The display screen 220 may display an image of an object to be photographed. The image pickup apparatus 100 may be housed in the housing 210. In one example, the camera device 100 may be used as a rear camera of the mobile terminal 200 to take a picture or record an external scene. In another example, the camera device 100 may also be used as a front camera of the mobile terminal 200 to implement a self-timer or video call function.

The camera device 100 can rotate slightly in the housing 210 to generate a slight angular displacement, so as to acquire images at different positions after rotation. The mobile terminal 200 may further include a position sensor, such as a hall sensor, electrically connected to the camera module 20, through which the pitch and yaw angles of the camera module 20 are sensed.

Referring to fig. 1a to 1c, an image capturing apparatus 100 according to an embodiment of the present disclosure may include a fixing frame 10, a camera module 20, a supporting portion, and a driving member (not shown).

The holder 10 may be fixed to the housing 210. The camera module 20 is disposed above the fixing frame 10. The supporting portion is disposed on the fixing frame 10 and supported on a side portion of the camera module 20. That is, the holder 10 supports a support portion, which supports the camera module 20. The driving member is used for driving the camera module 20 to rotate relative to the fixing frame 10, so that the optical axis O of the camera module 20 after rotation is inclined relative to the optical axis O of the camera module 20 at the initial position, so that the camera module 20 can acquire a plurality of images at a plurality of positions. In the initial state, that is, when the driving member does not drive the camera module 20 to rotate, the camera module 20 has an initial position at which the first image is acquired and stored. Then, the driving member drives the camera module 20 to rotate by a small angle relative to the fixing frame 10 to a second position, and a second image is obtained at the second position and stored. And then, the first image and the second image are synthesized and modified, so that an image with high resolution is obtained, and the image resolution is improved. But not limited thereto, the driving member may drive the camera module 20 to rotate to more positions relative to the fixing frame 10 to acquire more images, and perform a synthesizing modification on the plurality of images to improve the image resolution.

The camera device 100 according to the embodiment of the present disclosure supports the side of the camera module through the support portion, and drives the camera module to integrally rotate through the driving member to acquire a plurality of images at a plurality of positions, thereby realizing a clearer super-resolution image, and simultaneously, reducing the height of the camera device 100, and facilitating ultra-thinning of the mobile terminal 200.

For example, the fixing frame 10 can support the camera module 20, the elastic body 30 and the driving member. The holder 10 may have a hollow frame structure. Comprises four frames, namely a first frame 11, a second frame 12, a third frame 13 and a fourth frame 14. The overall size of the holder 10 may be slightly larger than the overall size of the camera module 20. The fixing frame 10 is fixed to the housing 210.

The camera module 20 includes an object side and an image side. The object side is the side close to the object to be shot, and the image side is the side close to the image. The camera module 20 is disposed above the holder 10, i.e., the holder 10 is located at the image side of the camera module 20. The camera module 20 may include a lens holder 21 and a lens 22 disposed on the lens holder 21. The lens holder 21 may have a substantially square structure, and has a receiving space for receiving and fixing the image sensor 23. The lens 22 is movable in the optical axis O direction with respect to the image sensor 23 to realize a focusing function. The lens 22 may also be tilted with respect to the image sensor 23 to implement an anti-shake function. The image sensor 23 is disposed on the circuit board 24. The circuit board 24 may be mounted to a main board of the mobile terminal 200 through a connector to electrically conduct the image sensor 23 with a processor on the main board for communication. The lens 22 is used for receiving incident light and refracting and converging the incident light to the image sensor 23 for imaging. The lens 22 may include a lens barrel and one or more lenses accommodated in the lens barrel and arranged in the direction of the optical axis O.

The image sensor 23 is configured to receive the incident light refracted and condensed by the lens 22 to form an image, and convert the optical image into an electrical signal. The image sensor 23 has a plurality of photosensitive pixels. The photosensitive pixels are used for receiving incident light and generating signal charges in proportion to the incident light intensity. For example, each light-sensing pixel may include a plurality of photodiodes for sensing light and logic circuitry for processing the detected light to produce electrical signals. The plurality of photosensitive pixels may be distributed in an array, such as a bayer array, to form a photosensitive region, and acquire an image of an object to be photographed. When the camera module 20 is at different positions, different photosensitive pixels can acquire different images of the object to be photographed. The image sensor 23 may be a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS).

A color filter (not shown) may be further disposed on the surface of the image sensor 23. The color filter comprises a plurality of filter units, and the filter units correspond to the photosensitive pixels one by one. The plurality of filter units respectively allow light of a specific wavelength to reach the photosensitive pixels. For example, the plurality of filter units may have a bayer array formed by one red filter unit R, two green filter units G, and one blue filter unit B. The red filter unit R can filter out red light in accordance with a red wavelength, the green filter unit G can filter out green light in accordance with a green wavelength, and the blue filter unit B can filter out blue light in accordance with a blue wavelength. Each photosensitive pixel receives the light intensity signal filtered by the corresponding filtering unit and converts the light intensity signal into an electric signal for recording.

A plurality of microlenses may be further provided on the upper surface of the color filter, i.e., the surface near the object side. The micro lenses correspond to the filtering units one by one. For example, the plurality of microlenses may be distributed in a bayer array. The microlens may be formed using a light-transmitting material. The microlenses may be hemispherical convex microlenses. The incident light is converged to the photosensitive pixels of the image sensor 23 by the microlenses, and the amount of light incident on the photosensitive pixels can be increased, so that the sensitivity of the image sensor 23 to the sensed light intensity can be increased, and the image quality can be improved.

The supporting portion includes at least one elastic body 30, one end of the elastic body 30 is connected to the fixing frame 10, and the other end is connected to the outer wall of the camera module 20 through a connecting member 40. As shown in fig. 3a to 3c, the elastic body 30 may be provided with a pair for supporting the camera module 20. The pair of elastic bodies 30 can be fixed to the fixing frame 10 and supported on the side of the camera module 20. But not limited thereto, the elastic body 30 may be provided with one, and the side of the camera module 20 is supported by one elastic body 30. As shown in fig. 1b, taking the pair of elastic bodies 30 as an example, the pair of elastic bodies 30 may be disposed opposite to each other and located at the side of the camera module 20. For example, the pair of elastic bodies 30 may be respectively provided at the first rim 11 and the third rim 13 of the fixing frame 10. The camera module 20 is floatingly supported on the holder 10 by elastic deformation (compression or elongation) of the pair of elastic bodies 30, so that the camera module 20 can rotate relative to the holder 10. The elastic body 30 may be rubber, or a compression spring.

The driving member is disposed at a side of the camera module 20, and may be fixed to the fixing frame 10 or fixed to the housing 210. The driving member is connected to the camera module 20, and drives the camera module 20 to rotate, so that the image sensor 23 of the camera module 20 is tilted with respect to a plane perpendicular to the optical axis O of the camera module 20 when in the initial position, that is, the optical axis of the camera module 20 after rotating is tilted with respect to the optical axis of the camera module 20 when in the initial position, so that the image sensor 23 can acquire a plurality of images at a plurality of positions.

Illustratively, the camera module 20 may rotate about the Y-axis or about the X-axis. Wherein the Y-axis may be a line connecting the pair of elastic bodies 30. The X-axis may be perpendicular to the Y-axis.

The driving member can be fixed on the fixing frame 10 on the connecting line Y-axis of the pair of elastic bodies 30. In the initial state of the camera module 20, the pair of elastic bodies 30 keep the camera module 20 balanced, and at this time, the image sensor 23 of the camera module 20 has a first position, that is, the initial position of the camera module 20, and in the first position, the image sensor 23 acquires a first image of an object to be photographed, and stores the first image in the storage unit of the mobile terminal 200. Then, the driving member drives the camera module 20 to rotate around the first axis X, at this time, one of the pair of elastic bodies 30 is compressed, the other elastic body 30 is pulled up and extended, and the image sensor 23 is tilted by a slight angle (slight angular displacement) with respect to a plane perpendicular to the optical axis O when in the initial position, that is, the optical axis of the camera module 20 after rotating is tilted by a slight angle with respect to the optical axis of the camera module 20 when in the initial position, and the slight angular displacement can enable the image sensor to achieve the effect of translation. To improve the resolution of the image, the camera module 20 may be rotated to move the image sensor 23 by a distance less than one photosensitive pixel, for example, 1/4 to 1/2 photosensitive pixels, relative to the initial position, so that the image sensor 23 reaches a second position at which a second image of the object to be photographed is acquired and stored in the storage unit in which the first image is stored. Thereafter, the first image and the second image are synthesized and modified by an image processing unit within the mobile terminal 200, thereby obtaining an image with high resolution and improving the resolution of the image. But not limited to this, the driving element may also drive the camera module 20 to rotate, so that the image sensor 23 reaches multiple positions, and different images are acquired at the multiple positions, so as to further improve the resolution of the images.

But not limited to this, the driving element may also be located on the X axis of the connection line of the pair of elastic bodies 30, and the camera module 20 is driven by the driving element to rotate around the Y axis, so that the image sensor moves by a distance less than one photosensitive pixel.

The camera device 100 according to the embodiment of the present disclosure, based on the driving element driving the camera module 20 to rotate integrally, the image sensor 23 can move by a distance less than the distance between two adjacent photosensitive pixels, thereby sensing a plurality of images at positions where the conventional image sensor cannot reach, obtaining images with high resolution by processing the plurality of images, and the camera module 20 rotating integrally acquires the plurality of images at the plurality of positions more clearly, thereby making the resolution of the synthesized super-resolution image stronger and improving the image quality. Since the elastic body 30 is supported by the side of the camera module 20, the camera module 20 is supported by the elastic body 30 in a floating manner, and at the same time, does not occupy the space, i.e., the height space, of the camera module 20 in the optical axis direction, so that the overall size of the whole camera device 100 can be reduced, the occupation of the thickness space of the mobile terminal 200 can be reduced, and the ultra-thinning of the mobile terminal 200 is facilitated.

Fig. 2b is a top view of the image pickup apparatus shown with the mount and the elastic body removed according to an exemplary embodiment of the present disclosure. Fig. 2c is a side view of the image pickup apparatus shown with the mount and the elastic body removed according to an exemplary embodiment of the present disclosure.

That is, the camera module 20 is supported on the elastic body 30 by the connection member 40. One end of the connecting piece 40 can be fixed on the outer wall of the lens base 21 by welding, and the other end is a free end which extends outwards to form a supporting wing. Wherein the elastic body 30 may be fixed to the support wing by glue. The driving end of the driving member may be connected to the connecting member 40, for example by gluing to the support wing. The elastic body 30 may be any one of the following: thermoplastic polyurethane, thermoplastic styrene, thermoplastic polyolefin, rubber, silica gel and other colloids. The elastic body 30 may also be a spring.

In one embodiment, the elastic bodies 30 are provided in two pairs, i.e., four. Each pair of elastic bodies 30 are disposed opposite to each other, and the camera module 20 rotates about a connection line (for example, Y-axis) between the first pair of elastic bodies 30, or the camera module 20 rotates about a connection line (for example, X-axis) between the second pair of elastic bodies 30. The four elastic bodies 30 support the camera module 20, so that the camera module 20 is supported more balance.

The first pair of elastic bodies may include a first elastic body and a second elastic body fixed to the first rim 11 and the third rim 13 of the fixing frame 10, respectively. The second pair of elastic bodies 30 may include a third elastic body and a fourth elastic body, which are respectively fixed to the second frame 12 and the fourth frame 14 of the fixing frame 10. The Y axis of the connection line between the first pair of elastic bodies 30 may be perpendicular to the X axis of the connection line between the second pair of elastic bodies 30, and both pass through the optical axis O of the camera module 20, and the optical axis O is perpendicular to the Y axis and the X axis, and the connection line between the first pair of elastic bodies and the connection line between the second pair of elastic bodies are parallel to the long side and the short side of the image sensor of the camera module, respectively. That is, a line between the first elastic body and the second elastic body is perpendicular to a line between the third elastic body and the fourth elastic body.

Correspondingly, the connecting members 40 may be provided in two pairs, one for each of the two pairs of elastic bodies 30. Each elastic body 30 is fixed at one end to the fixing frame 10 by glue and at the other end to the corresponding connecting member 40 by glue. But not limited thereto, the two pairs of connecting members 40 may be integrally formed to surround the outer wall of the camera module 20. For example, the integral attachment member 40 can be secured to the periphery of the mirror base 21 by welding.

The connecting line between the two pairs of elastic bodies is perpendicular to the optical axis O, so that when the camera module 20 is at the initial position, the planes of the two pairs of elastic bodies are perpendicular to the optical axis O, and the camera module 20 is kept balanced to obtain the first image at the initial position. The processing unit of the mobile terminal 200 compares, synthesizes and modifies the different images acquired by the rotated camera module 20 with the first image to obtain the super-resolution image. The driving member may be provided in two, including a first driving member and a second driving member. The first driving member and the second driving member are respectively disposed on the adjacent frames of the fixing frame 10. For example, the first driving member is fixed to the first frame 11 on the fixing frame 10, and is located on the Y axis, adjacent to the first elastic body. The second driving member is fixed to the second frame 12 of the fixing frame 10, and is located on the X-axis and adjacent to the third elastic body. The first and second drivers may be piezoelectric actuators, memory alloy wires or voice coil motors.

In one embodiment, the piezoelectric actuator is fixed on the fixing frame 10, and the driving end thereof is connected with the camera module 20.

When the image sensor moves less than a photosensitive pixel distance, such as 1/4 to 1/2 photosensitive pixels, on the Y-axis, the image sensor 23 reaches a second position where a different photosensitive pixel of the image sensor 23 acquires a second image of the object to be photographed (as shown in fig. 4 b) and stores the second image in a storage unit where the first image is stored. Then, the second driving member drives the camera module 20 to rotate, that is, the second piezoelectric actuator adjacent to the first piezoelectric actuator and located on the X axis is energized, the driving end thereof is extended to jack up the camera module 20, at this time, the third elastic body located on the X axis is extended, and the fourth elastic body opposite to the third elastic body is compressed, so that the camera module 20 rotates around the Y axis, the camera module 20 is inclined by a slight angle with respect to a plane perpendicular to the optical axis O when in the initial position, that is, the optical axis of the rotated camera module 20 is inclined by a slight angle with respect to the optical axis of the camera module 20 when in the initial position, and the image sensor 23 follows the camera module 20 to also incline by a slight angle, so as to achieve the effect of translation. When the image sensor moves less than one photosensitive pixel, for example, 1/4 to 1/2 photosensitive pixels, on the X-axis, the image sensor 23 reaches a third position where a third image of the object to be photographed is acquired (as shown in fig. 4 c) and stored in the storage unit where the first image and the second image are stored. Then, the first piezoelectric actuator is de-energized, and the output end of the first piezoelectric actuator is shortened, so that the camera module 20 rotates around the X axis in the opposite direction, at this time, the first elastic body located on the Y axis and the second elastic body located on the X axis return to the initial state, the image sensor 23 moves on the Y axis by a distance less than one photosensitive pixel, for example, a distance between 1/4 and 1/2 photosensitive pixels, the image sensor 23 reaches the fourth position, and at the fourth position, a fourth image of the object to be photographed is acquired (as shown in fig. 4 d), and is stored in the storage unit where the first image, the second image, and the quartered image are stored. Then, the first image, the second image, the third image and the fourth image are synthesized and modified by an image processing unit in the mobile terminal 200, so that an image with high resolution is obtained and the resolution of the image is improved.

In one embodiment, the driving member is a memory alloy wire, one end of the memory alloy wire is fixedly connected to the fixing frame 10, and the other end of the memory alloy wire is fixedly connected to the camera module 20.

In one embodiment, the driving members are at least two, which are respectively located at different directions of the side of the camera module 20, and drive the camera module 20 to rotate in different directions relative to the fixing frame 10. For example, the camera module 20 may be driven to rotate by two driving members, so that the camera module 20 moves by a distance of one photosensitive pixel in different directions.

Illustratively, four driving members may be provided, each disposed adjacent to the elastic body 30. Two driving members are located on the Y axis and two driving members are located on the X axis. The driving member is taken as a piezoelectric brake, that is, the first driving member is a first piezoelectric brake, the second driving member is a second piezoelectric brake, the third driving member is a third piezoelectric brake, and the third driving member is a fourth piezoelectric brake.

Then, the first piezoelectric actuator or the third piezoelectric actuator is powered off, the output end of the first piezoelectric actuator or the third piezoelectric actuator is shortened, the camera module 20 rotates around the X axis in the opposite direction, at this time, the first elastic body and the second elastic body return to the initial state, the image sensor moves by the distance of one photosensitive pixel on the Y axis, the image sensor 23 reaches the fourth position, and at the fourth position, the fourth image of the object to be photographed is acquired and stored in the storage unit which stores the first image, the second image and the scattered image. After that, the first image, the second image, the third image, and the fourth image are synthesized and modified by an image processing unit within the mobile terminal 200, thereby obtaining a full-color image.

According to a second aspect of the embodiments of the present disclosure, there is provided a mobile terminal, as shown in fig. 5, including the image capturing apparatus 100 of the first aspect.

The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a camera, a wearable device such as a watch, a smart band, etc.

According to the mobile terminal 200 of the embodiment of the present disclosure, the camera module 20 is driven to rotate integrally by the driving member, and the image sensor 23 can move by a distance less than the distance between two adjacent pixels, so that a plurality of images at positions where the conventional image sensor cannot reach are sensed, and a high-resolution image is obtained by processing the plurality of images. Since the supporting portion is supported by the side portion of the camera module 20, the camera module 20 is supported by the supporting portion in a floating manner, and does not occupy the space of the camera module 20 in the optical axis direction, so that the height of the whole image pickup apparatus 100 can be reduced, the occupation of the thickness space of the mobile terminal 200 can be reduced, and the ultra-thinning of the mobile terminal 200 is facilitated.

It is understood that "a plurality" in this disclosure means two or more, and other words are analogous. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. The singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It will be further understood that the terms "first," "second," and the like are used to describe various information and that such information should not be limited by these terms. These terms are only used to distinguish one type of information from another and do not denote a particular order or importance. Indeed, the terms "first," "second," and the like are fully interchangeable. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

It will be further understood that the terms "central," "longitudinal," "lateral," "front," "rear," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the present embodiment and to simplify the description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation.

It will be further understood that, unless otherwise specified, "connected" includes direct connections between the two without the presence of other elements, as well as indirect connections between the two with the presence of other elements.

It is further to be understood that while operations are depicted in the drawings in a particular order, this is not to be understood as requiring that such operations be performed in the particular order shown or in serial order, or that all illustrated operations be performed, to achieve desirable results. In certain environments, multitasking and parallel processing may be advantageous.
