In order to better understand the camera control method provided by the embodiment of the application. First, an electronic device to which the camera control method is applied will be briefly described.

Referring to fig. 2A, fig. 2A is a schematic flowchart of a camera control method according to an embodiment of the present disclosure. As shown in fig. 2A, the camera control method is applied to an electronic device, the electronic device includes a camera and a power key, the camera is disposed in the power key, and when the camera is not started, the camera is hidden inside the electronic device, the camera control method includes steps 201 and 203, which are as follows:

201. and acquiring a target touch parameter of the lifting power key and acquiring a target working state of the electronic device.

The target touch parameter may be: the target touch control duration can be understood as the duration of the user when the power key is lifted in the touch control process, the duration can be acquired by using a pressure sensor in a collection mode and the like, and the target touch control duration is determined according to the duration of the pressure sensor for collecting pressure value changes. The target working state may be, for example, a state in which the display screen is unlocked and bright and then the display screen is turned off and the face unlocking function is started, a state in which the display screen is turned off and the face unlocking function is not started, an interface state in which the face unlocking operation is executed, and the like. The interface state for executing the face unlocking operation may be understood as a state in which the face unlocking payment information is adopted, and specifically may be a state in which the face recognition is started for identity authentication when the mobile payment is adopted. There are, of course, other situations that are merely illustrative and not intended to be limiting.

202. And if the target working state is a preset working state, generating a camera starting instruction according to the target touch parameter.

Optionally, a possible method for generating a camera start instruction according to a target touch parameter includes steps a1-A3, which are specifically as follows:

a1, when the target working state is a screen state after the display screen is unlocked and bright, judging whether the target touch duration is in a preset touch duration interval;

if the target touch duration is within the preset touch duration interval, generating a camera starting instruction;

a2, or, when the target working state is a state that a display screen is turned off and a face unlocking function is started, if the target touch duration is less than a first preset touch duration threshold, generating a camera starting instruction, wherein the first preset touch duration threshold is a left end point of a preset touch duration interval;

and A3, or when the target working state is a screen-off state of the display screen, if the target touch duration is greater than a second preset touch duration threshold, generating a camera starting instruction.

The preset touch duration interval and the second preset touch duration threshold are set by experience values or historical data or by a user, the second preset touch duration threshold may be within the preset touch duration interval or outside the preset touch duration interval, and if the second preset touch duration threshold is outside the preset touch duration interval, the second preset touch duration threshold is usually smaller than the first preset touch duration threshold.

The steps A1, A2 and A3 are executed without the execution sequence, and are three alternative schemes in parallel.

Optionally, the camera start instruction is used to start the camera.

203. And controlling the lifting power key to lift outwards according to the camera starting instruction so as to pop up the camera, and starting the camera.

Optionally, the starting mode of the camera may be that the power key is lifted, and the camera is started after the lifting operation is completed, or the camera is started gradually in the process of lifting.

Optionally, the electronic device may further include a plurality of cameras, the cameras may be front cameras or rear cameras, each camera may be disposed on the lifting power key, and pixels of each camera may be different. When the camera is started, the camera can be started in different modes, for example, when the power key is raised, the camera which is exposed first can be started first, or after the raising operation is completed, the camera with lower pixels can be started first, and when the camera with lower pixels cannot complete the operation performed by the user, the camera with higher pixels can be started again, or all the cameras can be started simultaneously.

Optionally, the process of the electronic device performing the lifting operation may further include: the lifting power key can determine the lifting speed according to an application program started by a user, for example, when the human face is unlocked, the lifting operation can be quickly completed by adopting the speed V1 as the lifting speed or adopting a pop-up mode; when the user is taking a self-timer, the speed V2 can be adopted as the rising speed, the slow rising speed can give a dynamic feeling to people, and the user experience can be improved, wherein V1 is larger than V2, and the speed V1 and the speed V2 can be set through experience values.

Optionally, the camera can also be a rotary camera, when people's face is unlocked, the rotary camera rotates to the front of the electronic device and can be used as a front camera, when people take pictures, the camera can rotate to the back of the electronic device and can be used as a rear camera, the front of the electronic device can be understood as the side where the display screen of the electronic device is located, and the back of the electronic device is the side opposite to the display screen of the electronic device.

Optionally, after the camera is used, the camera may further perform retraction operation on the power key, and during retraction, the camera may retract at a constant speed, may retract at a variable speed, or may retract in other ways, which is only an example and is not limited specifically here.

In this example, when the electronic device is in different states, the camera start instruction is generated according to different touch durations, the start instruction can be generated in different durations, and camera control can be performed in a good fit with the use habits of the user, so that the user experience can be improved to a certain extent.

In a possible embodiment, since different users have different accuracies of time control when performing touch operations, the accuracy of generating the camera start instruction based on the touch duration may be low. A possible method for improving the accuracy of the camera in generating the command comprises steps B1-B4, which are as follows:

b1, the target working state is a screen-on state after the display screen is unlocked, and if the target touch duration is outside the preset touch duration interval, a target difference value of an interval midpoint between the target touch duration and the preset touch duration interval is obtained;

b2, if the absolute value of the target difference is smaller than a preset difference threshold, acquiring an action information set of a target user, wherein the target user is a user touching the lifting power key;

b3, determining a target starting probability value of the camera according to the action information set;

and B4, if the target starting probability value is larger than a preset probability value threshold, generating a camera starting instruction.

The target difference between the target touch duration and the midpoint of the preset touch duration interval may be positive or negative, and if the target difference is positive, the target touch duration may be greater than the value of the right endpoint of the preset touch duration interval, and if the target difference is negative, the target touch duration may be less than the value of the left endpoint of the preset touch duration interval. The preset difference threshold and the preset probability value threshold can be set through experience values or historical data.

Optionally, if the target difference is smaller than the preset difference threshold, the touch operation of the user may be determined as a suspected trigger operation, and the user may open the camera for use, but the camera is not recognized due to inaccurate control of the touch time.

In this example, the target touch duration which does not satisfy the preset touch duration interval may be determined again, and when the condition is satisfied, the operation corresponding to the target touch duration may be identified as the camera start behavior, so that the accuracy in generating the camera start instruction may be improved to a certain extent.

Alternatively, the motion information of the target user may be facial expression information and facial orientation. A possible method for determining the target starting probability value of the camera according to the action information comprises the following steps C1-C5:

c1, determining a target included angle between the sight of the target user and the display screen according to the face orientation;

c2, determining a first sub-starting probability value according to the target included angle;

c3, obtaining the target similarity between the facial expression information and preset facial expression information;

c4, determining a second sub-starting probability value according to the target similarity;

and C5, acquiring weights of the first sub starting probability value and the second sub starting probability value, and performing weight operation on the first sub starting probability value and the second sub starting probability value by adopting the weights to obtain the target starting probability value.

When determining a target included angle between the sight of the target user and the display screen, as shown in fig. 2B, the plane where the display screen is located is used as an xoy plane, one vertex of the display screen is used as an origin, the direction where the long edge of the display screen is located is an x axis, the direction where the short edge is located is a y axis, a straight line passing through the vertex and perpendicular to the plane where the display screen is located is used as a z axis to establish a coordinate system, the sight direction of the target user is the direction where the straight line passing through the point where the eyes are located and perpendicular to the plane where the face of the target user is located, and the direction is the direction in which the face faces.

Optionally, the method for determining the first sub-starting probability value according to the target included angle may be: the closer the target included angle is to ninety degrees, the greater the first child firing probability value is; the larger the target angle deviates from ninety degrees, the smaller the start probability value is, for example, the target angle is 30 degrees and 50 degrees, the first sub-start probability value corresponding to the target angle of 30 degrees is smaller than the first sub-start probability value corresponding to the target angle of 50 degrees, the target angle is 100 degrees and 120 degrees, and the first sub-start probability value corresponding to the target angle of 100 degrees is larger than the first sub-start probability value corresponding to the target angle of 120 degrees.

Optionally, the facial expression information may be represented by a facial expression image, and the target similarity between the facial expression information and the preset facial expression information may also be defined by the similarity between the facial expression image and the preset facial expression image. The larger the similarity of the target is, the larger the second sub-starting probability value is, and the smaller the similarity of the target is, the smaller the second sub-starting probability value is. The target similarity and the second sub-firing probability value may be linearly changed or non-linearly changed, and the non-linear change may be, for example, a quadratic function change form or a cubic function change form, and the like, which is merely an example and is not limited in particular. The preset facial expression image may be a normal face, a smiling face, or the like. The normal face can be understood as a facial expression image when the user does not experience fluctuation in emotion, and the preset facial expression image can also be a facial expression that the user does while taking a picture, for example, an expression of grin-through, a grimacing face, and the like.

Optionally, the weights of the first sub-starting probability value and the second sub-starting probability value may be set through experience values or historical data, and are preset fixed values, or weights obtained through training of a neural network model according to different users, and during training of the neural network model, a supervised learning model may be used for learning, for example, a conjugate gradient method. The input samples of the model may be user information, a first child launching probability value, a second child launching probability value, and a weight corresponding thereto. And when weight calculation is carried out, multiplying the first sub starting probability value by the corresponding weight, multiplying the second sub starting probability value by the corresponding weight, and adding the multiplication results to obtain the target starting probability value.

In the example, the target starting probability value is determined through the included angle between the sight of the target user and the display screen of the electronic device and the facial expression of the user, so that the target starting probability value can be determined according to the actual facial expression condition and sight condition of the user, the state of the user when using the electronic device can be more matched to a certain degree, and the accuracy of determining the target starting probability value is improved to a certain degree.

Optionally, the motion information of the target user may further include hand touch motion information, and the other method for determining the target starting probability value of the camera according to the motion information includes steps D1-D3, which are specifically as follows:

d1, determining shaking information when the target user touches the lifting power key according to the hand touch action information, wherein the shaking information comprises pressure value change information when the target user touches the lifting power key;

d2, determining the touch delay of the target user according to the pressure value change information;

d3, determining the target starting probability value according to the touch delay.

The hand touch action information can carry pressure value information of a user when the user touches the lifting power key. Because different users can be different in touch control lifting power supply, and simultaneously, because some users can have the condition of hand shake, the pressure value can fluctuate when touching, and then the touch control action can be finished, and because of the shake, the touch control duration is just fallen within or outside the preset touch control duration interval, the touch control instruction different from the touch control instruction that the user wants to reach is identified, and the user experience is reduced.

Optionally, the method for determining the touch delay of the target user according to the pressure value change information includes: and drawing a pressure value change curve according to the pressure value change information, determining a pressure value change period according to the pressure value change curve, and taking the pressure value change period as touch time delay.

Optionally, the method for determining the target start probability value according to the touch delay may be: extracting a time point when a user finishes touch operation, and if the time point is at a period point of a pressure value change period, determining that a camera starting instruction is generated directly according to the time point; as shown in fig. 2C, the horizontal axis is a time axis, denoted by t, and the vertical axis is a pressure value axis, denoted by f, the touch pressure value fluctuates at f1, the fluctuation is a possible periodic variation (illustrated by taking a positive selection variation as an example), if the time point is in the pressure value variation period, the difference between the time point and the period starting point of the period is obtained, determining a target starting probability value according to the ratio of the difference value to the period, if the right end point of the period is in a preset touch control time interval, if the ratio is larger, the target starting probability value is larger, and the ratio is smaller, the target starting probability value is smaller, if the left end point of the period is in the preset touch duration interval and the time point is not in the preset touch duration interval, the larger the ratio, the smaller the target firing probability value, and the smaller the ratio, the larger the target firing probability value.

In the example, the touch delay is determined through the touch action information of the hand of the user, the target starting probability value is determined according to the touch delay, and the target starting probability value can be determined according to the touch delay under the condition that the user shakes during touch, so that the accuracy of determining the target starting probability value can be improved to a certain extent.
