Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic diagram illustrating a flash adjustment apparatus according to an exemplary embodiment. As shown in fig. 1, the flash lamp adjusting device may be used in a terminal device such as a mobile phone, a tablet computer, or a camera, which is not limited herein. The flash adjustment device 100 includes: a first lens assembly 101 located on a side of the flash light source 400 facing the subject, wherein light emitted from the flash light source 400 is emitted through the first lens assembly 101; a control component 102 for generating a drive control command according to the shooting state; the driving unit 103 controls the movement of the first lens unit 101 according to the driving control command.

The embodiment of this disclosure sets up first lens subassembly in the orientation of flash light source by one side of object of shooing to control the removal of first lens subassembly according to the drive control command that the shooting state generated through control assembly, can adjust the light filling scope or the light filling region of flash light, carry out the light filling according to the demand of being shot the object, help improving the shooting effect, improve user's use experience.

The control component 102 may be a component known to those skilled in the art that can generate a driving control command according to a shooting status, for example, a component that can implement the generation of the driving control command by a general-purpose processor in combination with logic instructions, or a component that can implement the generation of the driving control command by a dedicated hardware circuit. The driving assembly 103 may be a component known to those skilled in the art, such as a motor and a worm gear, which can control the first lens assembly 101 to make corresponding movement according to a driving control command.

Wherein the shooting state may include one or more of the following parameters: the position of the object to be photographed in the image to be photographed; the ambient light state of the environment where the object to be photographed is located; a zoom state of the second lens assembly for photographing an image of the subject, etc., are not limited herein.

As one example, the position of the subject in the image to be photographed is taken as the photographing state. For example, the subject is a person, the position of the face of the person to be photographed in the image to be photographed is taken as a photographing state, and the control section 102 generates the drive control command according to the acquired position of the face of the person to be photographed in the image to be photographed. In which the position of the face of the person to be photographed in the image to be photographed can be determined using a person face recognition technique or the like.

As another example, an ambient light state of an environment in which the subject is located is taken as the shooting state. The ambient light state may refer to a set of light intensities of respective objects in an environment in which the photographed object is located. For example, the subject includes a person, the set of the light intensities of the respective subjects in the environment in which the subject is present is taken as the photographing state, and the control section 102 generates the drive control command according to the set of the light intensities of the respective subjects in the environment in which the subject is present. The light-receiving element can be used for detecting the light-entering amount of a lens assembly used for shooting the image of the shot object, and the light-entering amount is used for representing the ambient light state of the environment where the shot object is located.

In one possible implementation, the first lens assembly 101 may include one or more lenses. Fig. 2 is a schematic diagram illustrating a first lens assembly, according to an example embodiment. As shown in fig. 2, the first lens assembly 101 may include three lenses (a first lens, a second lens, and a third lens), a lens barrel, a filter, a holder, and the like.

And the optical axes of the first lens, the second lens and the third lens are positioned on the same straight line. The lens barrel may be used to accommodate the first lens, the second lens, and the third lens. The filter can reduce the influence of infrared light on noise from the outside (e.g., a CCD image sensor for imaging). The holder may function to support the filter and the lens barrel. Light emitted from the flash light source is emitted through the first lens assembly 101. Through adjusting the interval between first lens, second lens and the third lens each other, can adjust the focus and the aberration isoparametric of first lens subassembly 101 to adjust the light filling scope or the light filling region of flash light, help improving the shooting effect, improve imaging quality.

It should be noted that, although the first lens assembly 101 is described above with three lenses (a first lens, a second lens, and a third lens), a lens barrel, a filter, and a holder as an example, it should be understood by those skilled in the art that the present disclosure should not be limited thereto. Those skilled in the art can flexibly set the first lens assembly 101 according to the actual application scenario. For example, the first lens assembly 101 may adopt the same structure as a lens assembly used for capturing an image of a subject in a terminal device (e.g., a camera, a tablet computer, a mobile phone, or the like).

The first lens assembly in embodiments of the present disclosure may include one or more lenses. In the case where the first lens assembly includes one lens, the range of light irradiated from the flash to the subject can be adjusted by adjusting the position of the lens in the optical axis direction. Under the condition that first lens subassembly includes a plurality of lenses, through the interval between the each lens that the adjustment first lens subassembly includes, can adjust the focus and the aberration isoparametric of first lens subassembly to adjust the light filling scope or the light filling area of flash light in a flexible way.

In one possible implementation, in a case where the shooting state includes a zoom state of the second lens assembly, the control assembly 102 acquires the zoom state of the second lens assembly and generates a first drive control command according to the zoom state, and the drive assembly controls the intervals between the plurality of lenses according to the first drive control command. The second lens assembly is a lens assembly used for shooting the image of the shot object.

In one possible implementation, the control component 102 may generate a first drive control command according to the focal length value or the focal length variation value of the second lens component, and the first drive control command controls the spacing between the plurality of lenses to adjust the focal length value of the first lens component.

The zoom state may refer to a variation in the focal length of the second lens assembly. The angle of view of the shot may be changed by changing the focal length of the second lens assembly. For example, the finder range of shooting is enlarged or narrowed. Wherein the focal length of the second lens assembly can be represented by the distance from the optical center of the second lens assembly to the plane of the assembly (CCD in fig. 3) for imaging. Fig. 3 is a schematic diagram showing a photographing situation in a case of different focal lengths according to the related art. As shown in fig. 3, in the case where the relative position of the component for imaging and the subject to be photographed is not changed, if it is desired to expand the view range of photographing, the focal length of the second lens component can be controlled to be shortened. If it is desired to enlarge a photographed subject by reducing the range of view of the photographing, the focal length of the second lens assembly can be controlled to be longer.

For example, the zoom state of the second lens assembly may be represented by a focal length value of the second lens assembly after zooming. For example, the focal length of the second lens assembly after zooming is 20mm, and the zoom state may be that the focal length becomes 20 mm. As another example, the zoom state may also adopt a focal length change value before and after zooming of the second lens assembly. For example, the focal length of the second lens assembly before zooming is 5mm, the focal length after zooming is 20mm, and the zoom state may be a focal length change value +15 mm. The skilled person may also use other parameters to indicate the zoom state, such as a viewing angle parameter, etc., which are not limited herein.

The control component 102 may generate a corresponding first drive control command in accordance with the zoom state of the second lens component. In the case where the first lens assembly 101 includes a plurality of lenses. As an example, if the zoom state of the second lens assembly is such that the focal length becomes 20mm, the first drive control command may instruct the adjustment of the focal length of the first lens assembly 101 to 20 mm. As another example, if the zoom state of the second lens assembly is a focal length change value of +15mm, the first drive control command may instruct the focal length of the first lens assembly 101 to increase by 15 mm.

In the case where the first lens assembly 101 includes one lens, as an example, the control assembly 102 may generate a corresponding first drive control command according to a zoom state of the second lens assembly according to the zoom state. The first driving control command can control the first lens assembly 101 to move in the axial direction, so that the propagation path of light passing through the first lens assembly 101 is changed, and the purpose of adjusting the light supplement range or the light supplement area of the flash lamp is achieved.

It should be noted that, as those skilled in the art will understand, there are various methods available in the related art to implement the driving component 103 to perform the operation control on the first lens assembly 101 according to the first driving control command. Those skilled in the art can flexibly set the operation control method of the first lens assembly 101 according to the actual structure of the first lens assembly 101, and a few specific examples are given below.

In one possible implementation manner, the control component 102 acquires a zoom state of a second lens component, and generates a first driving control command according to the zoom state, wherein the second lens component is a lens component used for shooting an image of a shot object; the driving assembly 103 controls the spacing between the plurality of lenses according to a first driving control command.

In the case where the first lens assembly 101 includes a plurality of lenses, the first drive control command may be used to control the first lens assembly 101 to move in the axial direction as a whole. For example, the driving assembly 103 may control the first lens assembly 101 to move in the axial direction by a first distance as a whole according to a first driving control command. The first driving control command may also be used to adjust the spacing between the lenses included in the first lens assembly 101, so as to adjust parameters such as the focal length and the aberration of the first lens assembly 101. For example, the driving assembly 103 may adjust the spacing between the respective lenses included in the first lens assembly 101 according to the first driving control command. For example, the driving assembly 103 may control the first lens assembly 101 to move axially by a first distance as a whole according to a first driving control command, and adjust the spacing between the lenses included in the first lens assembly 101.

For example, a case where the first lens assembly 101 includes 4 lenses is taken as an example. Fig. 4a is a schematic diagram illustrating a positional relationship of a plurality of lenses in a first lens assembly before zooming according to an exemplary embodiment. Fig. 4b is a schematic diagram illustrating a positional relationship of a plurality of lenses in the post-zoom first lens assembly according to an exemplary embodiment. Wherein the lens 1011 can be kept fixed in position, and by changing the distance between the lens 1011 and the lens 1012, the optical center of the first lens assembly 101 can be changed, thereby adjusting the focal length of the first lens assembly 101. The distances between the

lenses

1012 and 1013, 1013 and 1014, and 1014 and 1015 are adaptively changed to improve the aberration of the first lens assembly 101 so as to obtain a better imaging effect. The focal length of the first lens assembly 101 corresponding to fig. 4b is larger than the focal length of the first lens assembly 101 corresponding to fig. 4 a.

According to the embodiment of the disclosure, under the condition that the first lens assembly comprises a plurality of lenses, parameters such as the focal length and the aberration of the first lens assembly can be accurately adjusted by adjusting the distance between the lenses included in the first lens assembly, so that the light supplement range or the light supplement area of the flash lamp can be flexibly adjusted.

In one possible implementation, the control component 102 acquires a position of the subject in the image to be captured, and generates the second drive control command according to the position.

For example, the position of the subject in the image to be captured may be determined by determining the position of the subject with respect to the center position of the image to be captured, with respect to the center position of the image to be captured. After the control component 102 acquires the position, a second driving control command may be generated according to the position, and the second driving control command may indicate a manner of moving the first lens component 101, such as a direction, or a distance, or a direction and a distance, where the direction and the distance may be obtained by calculation by a person skilled in the art in any manner based on parameters (such as a focal length, an angle of view, etc.) of the first lens component 101 and a position of a subject in an image to be captured. So that the driving assembly 103 can control the first lens assembly 101 to make adaptive movement according to the second driving control command. Other methods can be adopted by those skilled in the art to determine the position of the photographed object in the image to be photographed according to actual situations.

In one possible implementation, the driving assembly 103 moves to at least one direction according to the second driving command.

In one possible implementation, the moving of the driving component 103 to at least one direction according to the second driving command may include: moving in the horizontal direction; or in a vertical direction; or in both the horizontal and vertical directions.

The following example will be described with a plane on which a side of the first lens assembly 101 facing a subject is located as a reference plane.

In one possible implementation manner, the driving assembly 103 may include a component that can drive the first lens assembly 101 to move in the horizontal direction in the reference plane, for example, a component that can be controlled by a motor, can move in the horizontal direction, and the like. In one example, the second driving control command may instruct the first lens assembly 101 to move in a horizontal direction, and the driving assembly 103 may drive the first lens assembly 101 to perform a movement in the horizontal direction by a preset distance. In another example, the second driving control command may instruct the first lens assembly 101 to move a distance n in the horizontal direction, and the driving assembly 103 may drive the first lens assembly 101 to perform the movement of the distance n in the horizontal direction.

In one possible implementation, the driving assembly 103 may include a component that can drive the first lens assembly 101 to move in the vertical direction in the reference plane, for example, a component that can be controlled by a motor, can move in the vertical direction, and the like. In one example, the second driving control command may instruct the first lens assembly 101 to move in the vertical direction, and the driving assembly 103 may drive the first lens assembly 101 to perform a movement in the vertical direction by a preset distance. In another example, the second driving control command may instruct the first lens assembly 101 to move the distance m in the vertical direction, and the driving assembly 103 may drive the first lens assembly 101 to perform the movement of the distance m in the vertical direction.

In one possible implementation manner, the driving assembly 103 includes a component that can drive the first lens assembly 101 to move in the horizontal direction in the reference plane, and a component that can drive the first lens assembly 101 to move in the vertical direction, for example, a component that can be controlled by a motor, can move in the horizontal and vertical directions, and the like. In one example, the second driving control command may instruct the first lens assembly 101 to move in a horizontal direction and to move in a vertical direction, and the driving assembly 103 may drive the first lens assembly 101 to perform a movement in the horizontal direction by a preset distance and then perform a movement in the vertical direction by a preset distance, or perform a movement in the vertical direction by a preset distance and then perform a movement in the horizontal direction by a preset distance. In another example, the second driving control command may instruct the first lens assembly 101 to move a distance p in a horizontal direction and a distance q in a vertical direction, and the driving assembly 103 may drive the first lens assembly 101 to perform the movement by the distance p in the horizontal direction and then the movement by the distance q in the vertical direction, or to perform the movement by the distance q in the vertical direction and then the movement by the distance p in the horizontal direction.

It should be noted that those skilled in the art should understand that the second driving control command can also instruct the first lens assembly 101 to move in other directions besides the horizontal direction and the vertical direction.

The control assembly generates a corresponding second drive control command according to the position of the shot object in the image to be shot, so that the drive assembly can control the first lens assembly to move in the radial direction, and the light supplement range or the light supplement area of the flash lamp can be adjusted.

In one possible implementation, the control component 102 obtains an ambient light state and generates a command for controlling the flash light source to turn on or off based on the ambient light state.

In one possible implementation, the control component acquiring the ambient light state may include: the control component acquires the light entering amount of the first lens component, and determines the ambient light state according to the light entering amount of the first lens component.

For example, the control component 102 can obtain the ambient light status, and in one possible implementation, the ambient light status can be determined by comparing the amount of incoming light to a threshold. In one example, if the light entering amount is less than or equal to the threshold, it is determined that the ambient light state is dark and the flash lamp is required to supplement light, and the control component 102 may generate a command for controlling the flash lamp power to turn on, so that the driving component 103 controls the flash lamp power to turn on according to the command for controlling the flash lamp power to turn on. If the light entering amount is greater than the threshold, it is determined that the ambient light state is brighter without the need for flash light for light supplement, and the control component 102 may generate a command for controlling the flash light source to turn off, so that the driving component 103 controls the flash light source to turn off according to the command for controlling the flash light source to turn off. The threshold value may be set by a person skilled in the art according to actual needs, or may be a default of the system.

The control assembly generates a command for controlling the flash lamp light source to be turned on or turned off according to the ambient light state, so that the driving assembly controls the flash lamp light source to be turned on or turned off according to the command, and the light supplement condition of the flash lamp can be adjusted according to the actual condition.
