The following describes the control method provided by the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 1 shows a flowchart of a control method according to an embodiment of the present application, which is applied to an electronic device including two screens. The method in the embodiment comprises the following steps:

step S1: in the event that a target object and its shadow are identified in the target interface, a first input is received from a user.

The first input is used for adjusting an included angle between two screens of the electronic equipment to a first angle.

The first input comprises touch input and space input which are performed by a user on a screen, and is not limited to input such as clicking, sliding and the like; the first input also includes user input to physical keys on the device, not limited to press or the like. Furthermore, the first input includes one or more inputs, wherein the plurality of inputs may be continuous or intermittent.

The two screens are, by reference, a first screen and a second screen, respectively. The first screen is a main screen, and the second screen is a sub-screen. Under the condition that the main screen displays the target interface, a user can adjust the included angle between the two screens by turning the auxiliary screen, so that the included angle between the two screens is a first angle.

Alternatively, in this step, the target interface is any one of a shooting preview interface, an image editing interface, and the like.

In one scenario, a user enters a shooting mode of the electronic device, a first screen displays a shooting preview interface, and if a target object and a shadow thereof are identified in the shooting preview interface, the user can perform a first input.

In another scenario, a user enters an image editing mode of the electronic device, the first screen displays an image editing interface, and if a target object and a shadow thereof are identified in the image editing interface, the user can perform a first input.

In reference, under the condition that a target object and a shadow thereof are identified in a target interface, a control for triggering adjustment of a shadow angle is displayed, a user operates the control, and a function of adjusting the shadow angle is started, so that the user adjusts an included angle between two screens through first input.

Or, under the condition that the target object and the shadow thereof are identified in the target interface, the user adjusts the included angle between the two screens to a first angle, and then triggers a control for adjusting the shadow angle.

Step S2: and responding to the first input, and adjusting the included angle between the target object and the shadow thereof to a second angle.

Wherein the second angle is associated with the first angle.

In this embodiment, the included angle between the target object and the shadow thereof is used to represent the relative position relationship between the target object and the shadow thereof, and the orientation relationship between the target object and the shadow thereof can be represented from the included angle between the target object and the shadow thereof.

Optionally, the angle between the two screens and the angle between the target object and its shadow are set in advance in a correlated manner.

For example, it can be set as: as the angle of the included angle between the two screens is increased, correspondingly, the angle of the included angle between the target object and the shadow thereof is increased; conversely, as the angle between the two screens decreases, the angle between the target object and its shadow correspondingly decreases.

Accordingly, when the angle between the two screens is a first angle, correspondingly, the angle between the target object and its shadow is a second angle associated with the first angle.

Referring to FIG. 2, target object 1 and its shadow 2 may both be considered particles, and thus the coordinates of target object 1 and its shadow 2 may be determined in the target interface. Further, a horizontal line is taken as a reference line 3, and an included angle between a connecting line between the target object 1 and the shadow 2 thereof and the reference line 3 is taken as an included angle between the target object 1 and the shadow 2 thereof.

In reference, a reference line 3 is set on one side of the target object 1 with the target object 1 as a standard. Referring to fig. 2, a reference line 3 is located on the left side of the target object 1.

Specifically, in the case where the target object is a person, a reference line is set in the front vertical direction of the face of the person.

Further, the angle between the two screens ranges from 0 ° to 180 °, which is mapped as: the included angle between the shadow and the target object is 0-180 degrees. That is, the angle between the two screens corresponds to the angle between the shadow and the target object. Referring to fig. 2, for example, the angle between the two screens is 120 °, corresponding to 120 ° between the shadow 2 and the target object 1.

Optionally, the angle between the target object and its shadow is displayed in real time, which is helpful for the user to adjust.

In addition, the embodiment of the application can be applied to an image editing scene besides the shooting scene, so that the expected effect can be achieved at a later stage by adjusting the included angle of the target object and the shadow thereof in the photo. Therefore, based on the image editing method provided by the embodiment, the user does not need to adjust the shooting position in the shooting process, the shooting technical requirement on the user is low, and the user operation is simple; meanwhile, the operation of the user in the image editing scene is simpler, so that the editing operation of the user is simplified.

In a flow of a control method according to another embodiment of the present application, before receiving the first input from the user, the method further includes:

step A1: a first light source forming a shadow is identified in the target interface.

Optionally, the first light source comprises a light emitting object such as the sun, a light, etc.; the first light source also includes light rays, etc.

Step A2: and determining the relative position relation of the first light source, the target object and the shadow thereof.

Optionally, an image recognition technology is first used to recognize the three elements, i.e., the first light source, the target object and the shadow thereof, in the target interface, then position information (e.g., coordinate information) of each element in the target interface is respectively obtained, and angles of each included angle are calculated through the position information and a trigonometric function, so as to further determine a target relative position relationship between the three elements.

Referring to fig. 2, the relative target position relationship includes an angle between the first light source 4 and the target object 1, and an angle between the target object 1 and its shadow 2.

The included angle between the first light source 4 and the target object 1 is: the connecting line between the first light source 4 and the target object 1 forms an included angle with the reference line 3; the included angle between the target object 1 and the shadow 2 is as follows: the connecting line between the target object 1 and the shadow 2 and the reference line 3.

Referring to fig. 2, specifically, for example, the incident direction of the first light source 4 is calculated by an angle between the first light source 4 and the target object 1, and then the detail correction is performed by an angle between the target object 1 and the shadow 2 thereof, and further, the relative position relationship of the target is determined based on the corrected position relationship of the three.

For another example, the incident direction of the first light source 4 is calculated by the angle between the target object 1 and the shadow 2 thereof, and then the angle between the first light source 4 and the target object 1 is corrected for details, and further, the target relative position relationship is determined based on the corrected position relationship of the three.

Generally, following a natural law, the relative positional relationship of the targets indicates that the three are on a straight line.

Correspondingly, the relative position relationship of the target includes the relative position relationship of the first light source, the target object and the shadow thereof on a straight line.

According to the control method, the shadow effect in the image can be adjusted in the image irradiated by the light source. In order to pursue the real shooting effect of the image, the relative position relation of the light source, the target object and the shadow thereof is used as an adjustment basis. Therefore, in the present embodiment, in the case of recognizing the light source, the target object, and the shadow thereof, the target relative positional relationship among the three is determined.

In the flow of the control method according to another embodiment of the present application, after step S2, the method further includes:

step B1: and determining the first position of the first light source according to the target relative position relation and the second angle.

Step B2: the first light source is adjusted to a first position.

In the natural law, the position of the light source affects the orientation of the shadow, and the position of the light source and the orientation of the shadow are opposite to each other based on the irradiated object. For example, the light source shines on the object from the left side, and the shadow is oriented to the right. Therefore, when the angle between the shadow and the target object changes, the orientation of the shadow also changes, and correspondingly, the position of the light source also changes according to the projection principle.

Therefore, in this embodiment, according to the natural law, after the included angle between the target object and the shadow thereof is adjusted to the second angle, the position of the first light source is adjusted based on the target relative position relationship.

In this embodiment, the following is actually taken as a reference based on the relative positional relationship of the target: and calculating to obtain the position relation in the three-dimensional world based on the position relation of the identified first light source, the identified target object and the shadow thereof in the two-dimensional plane, so as to form a nonlinear regulation formula and meet the natural law of the light source and the shadow.

Optionally, an adjustment formula is generated according to the relative position relationship of the target, so that the position of the light source is adjusted according to the adjustment formula.

In this embodiment, in the image irradiated by the light source, the angle of the included angle between the target object and the shadow thereof is adjusted based on the natural law, and the position of the first light source is adjusted at the same time, so that the image content in the image is more real. Therefore, the embodiment can ensure the real effect of the image while simplifying the user operation.

In the flow of the control method according to another embodiment of the present application, in step S2, after responding to the first input and before adjusting the included angle between the target object and its shadow to the second angle, the method further includes:

substep C1: the first light source is adjusted to a second position. Wherein the second position is associated with the first angle.

In this embodiment, another method for adjusting the angle between the target object and its shadow is provided.

In this embodiment, the user adjusts the angle of the included angle between the two screens through the first input, and correspondingly, the first light source in the target interface changes the position along with the change of the angle of the included angle between the two screens.

Optionally, the angle between the two screens is set in advance in association with the position of the first light source.

For example, as the angle between the two screens becomes larger, the position of the first light source changes to the left; conversely, as the angle between the two screens becomes smaller, the position of the first light source changes to the right.

For another example, when the included angle between the two screens is a first angle, the position of the first light source is correspondingly a second position.

Substep C2: and determining a second angle according to the relative position relation of the target and the second position.

In the natural law, the orientation of the shadow is influenced by the position of the light source, and the position of the light source and the orientation of the shadow are opposite. Therefore, when the position of the light source changes, the orientation of the shadow changes, and correspondingly, the angle between the shadow and the target object changes.

Therefore, in this embodiment, according to the natural law, after the position of the first light source is adjusted, the included angle between the target object and the shadow thereof is adjusted based on the relative position relationship of the target.

Optionally, an adjustment formula is generated according to the relative position relationship of the target, so that the included angle between the target object and the shadow thereof is adjusted according to the adjustment formula.

In this embodiment, the user may further adjust the position of the first light source through the first input, so as to adjust an included angle between the target object and the shadow thereof in the target interface based on the change of the position of the first light source, thereby providing a further shortcut operation for the user to simplify the user operation. In addition, in the image irradiated by the light source, the position of the first light source is adjusted according to the natural law, and meanwhile, the included angle between the target object and the shadow thereof is correspondingly adjusted, so that the image content of the image is more real. Therefore, the embodiment can ensure the real effect of the image while simplifying the user operation.

step D1: and adjusting the shape of the shadow according to the second angle.

Wherein the shape includes at least a length and a contour.

On the one hand, in the natural law, the sun illumination is related to the length of the shadow, and the smaller the sun altitude angle is, the longer the shadow is, otherwise, the shorter the shadow is. Therefore, when the angle of the included angle between the target object and the shadow thereof changes, the solar altitude also changes according to the natural law, so that the length of the shadow is required to be adjusted while the angle of the included angle between the target object and the shadow thereof is adjusted.

On the other hand, along with the change of the included angle between the target object and the shadow thereof, the shadow can be distorted to a certain extent according to the viewport rule of the real world. Therefore, when the included angle between the target object and the shadow thereof is adjusted, the outline of the shadow is also required to be adjusted according to the natural law, so that the outline can show the distortion change.

Referring to fig. 3 and 4, when the angle of the included angle between the target object (character) and the shadow thereof is changed, the position of the first light source (sun) is changed, and the length and the contour of the shadow are changed.

In the embodiment, the shape of the shadow is adjusted, so that the whole image scene conforms to the objective law of the real world, and therefore, the embodiment can ensure the real effect of the image while simplifying the operation of a user.

In the flow of the control method according to another embodiment of the present application, before step S1, the method further includes:

step E1: in the event that a target object is identified in the target interface, a second input is received from the user.

The second input comprises touch input and space input which are performed by a user on a screen and are not limited to input of clicking, sliding and the like; the second input also includes user input on physical keys on the device, and is not limited to pressing or the like. Also, the second input includes one or more inputs, wherein the plurality of inputs may be continuous or intermittent.

The second input is used for adding a second light source in the target interface, so that a light and shadow effect can be presented in the target interface.

And in an application scene, for example, a camera is started to shoot a portrait, the shooting preview interface is used as a target interface, a target object can be identified in the shooting preview interface, and a user is prompted to perform light and shadow simulation. Therefore, based on the prompt, the user can trigger the control of the light and shadow simulation through the second input, add the second light source in the target interface, and start the light and shadow simulation function. In the light and shadow simulation function, the implementation mode of carrying out orientation transformation on the shadow by using the included angle characteristic of the folding screen is started.

Step E2: in response to a second input, a second light source is generated in the target interface.

Wherein the second light source is an analog light source. The analog light source includes at least one of a light emitting object and a light.

Optionally, the second light source is randomly positioned in the target interface.

Step E3: and generating a shadow corresponding to the target object in the target interface according to the first relative position relation between the second light source and the target object and the outline of the target object.

Optionally, the position of the shadow is determined according to a relative relationship between the second light source and the target object, so that the shadow, the second light source and the target object are located on the same straight line.

Further, after the position of the shadow is determined, the shadow of the target object is drawn according to the outline of the target object.

Optionally, based on the simulated second light source, the target object and its shadow, the user may adjust the position of the three through the first input.

In the embodiment, in a shooting scene, a light source can be simulated, a shadow can be drawn, and a scene irradiated by light effect in the real world is created for a single picture, so that a novel image shooting method is provided, and the shooting experience of a user is improved.

In addition, the embodiment of the application can also be applied to an image editing scene to perform light and shadow simulation on images without light rays and shadows, so that stereoscopic impression and sense of reality are increased.

In the flow of the control method according to another embodiment of the present application, after step S2, the user may click the "take picture" button to complete the taking picture. Alternatively, the user may also click on the "save" button to complete the image editing.

The embodiment of the application is preferably applied to shooting scenes and editing scenes of the character images, so that expected shadow effects are presented in the character images.

In summary, the embodiments of the present application are: a method for dynamically adjusting the shadow of a portrait based on a folding screen is provided. The problem of the camera position is often removed because light and shadow can't the adjustment position angle when shooing is solved, make the user can utilize light and shadow in a flexible way, improve the film forming rate of shooing under the sunshine. On one hand, shooting in a sunlight scene, and dynamically adjusting the included angle between the shadow of the figure and the figure through the folding angle of the folding screen to finish the panoramic composition of the figure and the shadow during shooting; on the other hand, the method is used for photographing in a scene with weak sunlight, simulating a light source, calculating the incident angle between the light source and a person, calculating the included angle and the area between the shadow and the person at the moment, forming shadow mapping in a picture, and increasing the stereoscopic impression and the sense of reality.

The control method of the embodiment not only can make the outline of the shadow clear, but also can shadow the shadow based on the adjustment of the included angle between the target object and the shadow thereof, so as to meet different requirements of users and achieve the expected effect.

Therefore, in the case where the target interface of the present embodiment is the shooting preview interface, the target object and the shadow thereof can be recognized. Further, the user can adjust the included angle between the two screens through a preset first input. Therefore, on the basis of presetting the relevance of the included angle between the two screens and the included angle between the target object and the shadow thereof, when the user adjusts the included angle between the two screens to a first angle, correspondingly, the included angle between the target object and the shadow thereof is also adjusted to a second angle relevant to the first angle.
