S101: Adjust pixel distribution of at least one image sensing unit, to change a ratio of pixels distributed along two directions in a respective effective region of the at least one image sensing unit, wherein the effective region is a region in which light through a lens that is in an imaging system and corresponds to an image sensing unit is imaged on the image sensing unit; the two directions comprise a first direction and a second direction that are parallel with the image sensing unit and orthogonal to each other; and the image sensing unit comprises a plurality of pixels adjustable in distribution, and the plurality of pixels is used for recording multidirectional view information of a same object of a scene.
S102: Capture an image of the scene by using the imaging system.
The image sensing unit according to this embodiment of the present application comprises a plurality of pixels and is adjustable in pixel distribution, for example, intervals between at least partial pixels can be adjusted by controlling the image sensing unit to be at least partially deformed, thereby changing the pixel distribution in the image sensing unit. For example, in a practical application process, an image sensor of the imaging system may be considered as a whole, the image sensor is divided into a plurality of imaging regions, each of which corresponds to one lens in the imaging system, then the imaging regions become the image sensing units according to this embodiment of the present application, the pixel distribution is adjustable, and light through the lens is imaged on the corresponding image sensing unit; or the image sensor of the imaging system comprises a plurality of relatively independent image sensing units distributed in array and adjustable in pixel distribution, and the image sensing unit and the lens in the imaging system are disposed corresponding to each other. The image sensing unit is adjustable in pixel distribution and a specific structure and form of the device are not limited.
For example, the image sensing unit may be a flexible image sensing unit, the flexible image sensing unit has been used in photographing devises, and in the present application, the flexible image sensing unit can be subject to telescopic deformation to some extent by actions such as external force, thereby changing the pixel distribution of the image sensing unit.
For another example, the image sensing unit may comprise a plurality of pixels distributed in array, at least two pixels are connected by an elastic part, or a controllable deformed material parts (such as a light-induced deformed material part, a magnetic deformed material part, or a piezoelectric deformed material part) and other deformable connecting parts, to form a whole imaging surface. The external force or external field can act on the deformable connecting part to control deformation of the corresponding connecting part, and achieve the objectives of adjusting the interval between the at least two pixels and changing the pixel distribution of the image sensing unit.
It should be understood that according to practical application requirements, the flexible image sensing units and the image sensing units distributed in array may be combined for use, and form the image sensing unit adjustable in pixel distribution. In a situation in which the image sensor is a whole, the image sensor and the image sensing units may have same or similar structures, and details are not further described.
In the imaging system, a region in which light through the lens (the light may come from but is not limited to an object or a real image or virtual image of an object in the scene) is imaged on the image sensing unit is generally round, pixels of the image sensing unit in the round region record the information such as multidirectional view information corresponding to the light, and pixels of the image sensing unit outside the round region do not actually record light information; therefore, a region in which light through a lens is imaged on a corresponding image sensing unit (such as the round region) is referred to as an effective region of the image sensing unit, and other regions except the effective region of the image sensing unit are ineffective regions.
Generally, the effective region of the image sensing unit is a round region, quantities of pixels of the image sensing unit distributed in different directions in the effective region are equal, a ratio of the quantities of the pixels distributed along the different directions in the effective region (that is, a pixel ratio) is 1, for example, quantities of pixels distributed in two directions (the first direction and second direction) perpendicular to and orthogonal to the normal line in the effective region are equal, and the pixel ratio is 1, the effective region provides pixel quantities of a same proportion for recording parallax information in the two directions, and proportions of the amount of information in the two directions in the view information captured into the effective region are equal.
However, in some situations, such as situations of multiview information image generation and 3D reconstruction, view information in different directions has different meanings and/or actions for practical application. For example, in a scene in which a multiview information image is generated by using image information captured by the imaging system, view information in a direction may be particularly focused, more different view images in this direction are desired to be generated, and focus on view information in a direction perpendicular to the above direction is less. For another example, in a scene in which 3D reconstruction is performed by using image information captured by the imaging system, as human eyes are more sensitive to horizontal direction views, it is expected to acquire more images of different parallaxes in horizontal direction to reconstruct a 3D scene, and human eyes are insensitive to perpendicular direction views. In a traditional manner for image capture, view information of a same proportion in different directions can be acquired, but in this capture manner, pixel resources of the image sensing unit are not fully used to meet requirements for differential proportions of view information in different directions.
According to this example embodiment of the present application, a characteristic of an image sensing unit in adjustable pixel distribution is fully used, and by adjusting the pixel distribution of the image sensing unit, in an effective region of the image sensing unit, pixels distributed along a first direction and a second directions are different in interval, that is, the pixel distribution of the image sensing unit is adjusted to cause quantities of the pixels distributed along the first direction and the second direction to be different, and the pixel ratio is not equal to 1; in this way, when an imaging system with the image sensing unit subject to pixel distribution adjustment captures an image of a scene, proportions of parallax information actually recorded by the image sensing unit in a first direction and a second direction can be changed, and differential capture of view information in different directions can be implemented.
The region in which the light through the lens is imaged on the image sensing unit is round, that is, the shape of the effective region of the image sensing unit is round. As shown in
After the pixel distribution of the image sensing unit is adjusted, as shown in
A pixel distribution characteristic of the effective region after the pixel distribution adjustment is related to a manner of adjustment of the pixel distribution of the image sensing unit, the pixel distribution of the image sensing unit may be flexibly adjusted, for example, the at least one image sensing unit is controlled to be deformed, to increase the quantity of the pixels distributed along the first direction and/or reduce the quantity of the pixels distributed along the second direction in the effective region of the image sensing unit, to cause the ratio of the pixels distributed in the two directions of the effective region after the pixel distribution adjustment to meet practical application requirements. For example, an interval between pixels distributed along a direction (such as the first direction or the second direction) in the effective region may be increased, to increase a quantity of the pixels distributed along the direction in the effective region; and/or an interval between pixels distributed along a direction (such as the first direction or the second direction) in the effective region may be reduced, to reduce a quantity of the pixels distributed along the direction in the effective region Pixel distribution characteristics of the effective region that are possibly generated after the pixel distribution of the image sensing unit is adjusted are described by using examples hereinafter.
In one possible situation, as shown in
In another possible situation, as shown in
In another possible situation, as shown in
A possible situation may also comprise: in the image sensing unit after pixel distribution adjustment, the quantities of the pixels along the two directions in the shape-changed effective region are both increased but increased by different quantities to change the ratio of the pixels distributed in the two directions, or a possible situation may comprise: in the image sensing unit after pixel distribution adjustment, the quantities of the pixels along the two directions in the shape-changed effective region are both reduced but reduced by different quantities to change the ratio of the pixels distributed in the two directions, and thereby differential capture of view information in the two directions is implemented by changing the pixel ratio.
In this example embodiment of the present application, the first direction and the second direction are flexibly determined under the premise of being perpendicular to the normal line and orthogonal to each other, which is not limited in present application. Optionally, the first direction is a horizontal direction perpendicular to the image sensing unit. Research shows that human eyes (left eye and right eye) are in horizontal distribution, which causes that human vision is more sensitive to horizontal direction view information and insensitive to vertical direction view information to some extent; therefore, in an image capture process, the view information in the horizontal direction and the vertical direction has different impact on human eye vision in scenes such as a 3D reconstruction scene, and the view information in the horizontal direction is more focused or required than the view information in the vertical direction. By determining the horizontal direction parallel with the image sensing unit as the first direction and the vertical direction parallel with the image sensing unit as the second direction, differential capture of view information in different directions by the image sensing unit can be implemented, a proportion of view information in the first direction (horizontal direction) is increased in image information captured by the image sensing unit, and/or a proportion of view information in the second direction (vertical direction) is reduced in the image information captured by the image sensing unit, and thereby an actual use ratio of a resource is improved and a practical application requirement on diversity is better met.
According to this example embodiment of the present application, by adjusting the pixel distribution of the image sensing unit, the pixel distribution in the effective region of the image sensing unit can be changed, and an actually changed pixel quantity in the effective region is related to a pixel quantity and relative position of the image sensing unit. Optionally, before the capturing an image of the scene by using the imaging system, the method further comprises: rotating the at least one image sensing unit around a respective normal line, to increase the quantity of the pixels distributed along the first direction of the at least one image sensing unit. For example, as shown in
The imaging system in this example embodiment of the present application may be applied has a characteristic of recording view information of a same object in different directions in a scene by using a plurality of pixels.
Optionally, the imaging system comprises a camera array, as shown in
Optionally, the imaging system may comprise a light field camera, as shown in
With reference to any image capture control method provided in the embodiments of the present application, optionally, before the capturing an image of the scene by using the imaging system, the method further comprises: translating the image sensing unit along a respective normal line to enlarge the effective region in which the light through the corresponding lens is imaged on the image sensing unit. The movement of the image sensing unit along the normal line changes the size of the effective region in which the light through the lens corresponding to the image sensing unit is imaged on the image sensing unit, for example, the image sensing unit is moved along with the normal line to the direction in which the distance between the image sensing unit and the corresponding lens is increased, that is, the image sensing unit is moved along the normal line to the direction away from the lens, and the effective region in which the light through the lens is imaged on the image sensing unit is enlarged. Since in the solution, the image sensing unit is translated along the normal line to enlarge the effective region in which the light through the corresponding lens is imaged on the image sensing unit, to cause the maximal variable range of the ratio of the pixels distributed along the first direction and the second direction in the effective region to be accordingly increased, thereby the adjustment flexibility of the ratio of the pixels distributed in the two directions is increased, universality of the solution is increased, and the practical application requirement on diversity is met. It should be understood that the operation of translating the image sensing unit along the normal line may be performed before or after the operation of adjusting the pixel distribution of the image sensing unit and/or rotating the image sensing unit, and the implementation manner is very flexible. In addition, the focusing state when the imaging system performs image capture may be changed by the translation of the image sensing unit along the normal line, and in this situation, whether the focusing compensation is required is determined according to actual needs. For example, if the focusing compensation is required, manners comprising but not limited to the manner of adjusting the focus length of the lens may be used, to cause the adjusted focusing position to be close as far as possible to or overlapped with the focusing position before the adjustment, or cause the adjusted focusing position to fall into a refocusing range allowed before the imaging system is adjusted; in some situations, such as a situation in which the adjustment of the focusing position affects the image capture little or the adjusted focusing position still falls into the refocusing range allowed before the imaging system is adjusted and the like, the focusing compensation is not required.
Further, with reference to any image capture control method provided in the embodiments of the present application, optionally, before the adjusting pixel distribution of at least one image sensing unit, the method further comprises: determining the first direction. After the first direction is determined, according to a relationship between the first direction and the second direction, the second direction is determined, and differential capture of view information in the first direction and the second direction is implemented. In the solution, directions of differential capture of view information may be determined according to actual requirements, the implementation manner is flexible and the practical application requirement on diversity is met.
Optionally, the determining the first direction comprises: determining the first direction according to an image capture mode of the imaging system. Scanning output manners of the image capture information corresponding to different image capture modes may vary, in order to facilitate the scanning output of the differential view information capture, the first direction may be determined at least according to the image capture mode of the imaging system. For example, the image capture modes may comprise but are not limited to a horizontal shooting mode and a vertical shooting mode, for example, the reverse direction of the image sensing unit corresponding to the horizontal direction relatively sensitive to human eyes when an image capture apparatus such as a camera is in the horizontal shooting mode is different from the reverse direction of the image sensing unit corresponding to the horizontal direction relatively sensitive to the human eyes when the camera is in the vertical shooting mode, and a reference direction corresponding to the image capture mode of the imaging system may be determined as the first direction according to a mapping relationship between the image capture mode and the reference direction. The solution causes the determination of the first direction to be adaptive to the image capture mode. As shown in
Optionally, the determining the first direction comprises: determining the first direction according to an image analysis result of the scene. In natural world, object distribution of the scene presents a rule, for example, under the action of gravity, the scene (for example, a “mountain”) may represent a distribution rule such as a large bottom and a small top, and the distribution rule helps to determine the horizontal direction and the vertical direction, and is used as the basis for determining the second direction, to implement differential capture of view information in two directions such as the horizontal direction and the vertical direction.
A person of ordinary skill in the art should understand that in any method of the embodiments of the present application, numbers of steps do not mean the execution sequence, the execution sequence of steps should be determined according to functions and internal logic without causing any limitation to the execution process of the embodiments of the present application in any form.

The external force or external field can act on the deformable connecting part to control deformation of the corresponding connecting part, and achieve the objectives of adjusting the interval between the at least two pixels and changing the pixel distribution of the image sensing unit.
It should be understood that according to practical application requirements, the flexible image sensing units and the image sensing units distributed in array may be combined for use, and form the image sensing unit adjustable in pixel distribution. In a situation in which the image sensor is a whole, the image sensor and the image sensing units may have same or similar structures, and details are not further described.

There is no limitation to the manners in which the image capture control apparatus is embodied. For example, the image capture control apparatus may be an independent part; or the image capture control apparatus may be a functional module integrated in an imaging device, wherein the imaging device may comprise but is not limited to an electronic device such as a camera, a video camera, a mobile phone or a tablet computer having a camera shooting or photographing function, which is not limited in this embodiment of the present application.
