Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant disclosure and are not limiting of the disclosure. It should be noted that, for the convenience of description, only the parts relevant to the related disclosure are shown in the drawings.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
With continued reference to FIG. 1, a flow 100 of one embodiment of a method of capturing an image according to the present disclosure is shown. The method for shooting the image comprises the following steps:
In this step, the execution subject on which the method of capturing an image is executed may display a frame in which a picture captured by the camera can be displayed in the screen, and the display picture in the frame may include a picture corresponding to the first position and a picture corresponding to the second position, for example, the picture corresponding to the first position may be a middle-upper half picture in the frame, and the picture corresponding to the second position may be a middle-lower half picture in the frame.
Alternatively, the in-finder display screen may include an oblique screen; pictures in different locations may also be included. The first position and the second position of the display picture in the view finder are respectively a position which is relatively close to the camera and a position which is relatively far away from the camera in the inclined plane in the display picture.
The execution main body displays a display picture in the view-finding frame in the screen, receives a click operation executed by a user on a first position in the display picture, and controls the voice coil motor to move continuously based on a contrast focusing principle, so that the camera focuses on the first position of the display picture in the view-finding frame, and the display picture at the first position is clear. The execution main body acquires a first image acquired by the camera focusing the first position on the basis of focusing the first position of the camera, wherein the first image comprises an image picture with a clear first position and a fuzzy second position.
And step 120, adjusting the position of the voice coil motor of the camera based on the position adjustment information of the preset voice coil motor acquired in advance, so that the camera focuses on the second position in the display picture, and acquiring a second image acquired by focusing on the second position.
In this step, after the execution main body acquires the first image with a clear first position in the display screen, the execution main body acquires position adjustment information of a preset voice coil motor in advance, where the position adjustment information may be used to adjust the position of the preset voice coil motor, and the camera focuses on different positions by adjusting the position of the preset voice coil motor, where the position adjustment information of the preset voice coil motor includes movement data of the preset voice coil motor when the focused position moves from the first position to the second position in the display screen. After the execution main body acquires the position adjustment information of the preset voice coil motor, the position of the voice coil motor of the camera is adjusted according to the position adjustment information, so that the camera focuses on a second position in the display picture, and then a second image acquired by focusing the second position is acquired, wherein the second image comprises an image picture with a clear second position but a fuzzy first position.
In some optional implementations of this embodiment, the pre-obtained position adjustment information of the preset voice coil motor includes: and presetting moving data of the voice coil motor when the focusing position corresponding to at least one preset step length parameter of the voice coil motor in a one-to-one mode moves from the first position to the second position in the display picture. The execution main body can acquire a step length parameter of a voice coil motor of the camera, and position adjustment information of the voice coil motor of the camera is determined based on a proportional relation between the step length parameter of the voice coil motor of the camera and the preset step length parameter and the preset parameter corresponding to the movement data.
Specifically, the execution body stores position adjustment information of a preset voice coil motor in advance, and may store at least one preset step parameter, where each preset step parameter corresponds to a piece of movement data, and the movement data may be movement data of the preset voice coil motor when the focusing position of the camera moves from a first position to a second position in the display screen. The preset moving data corresponding to the voice coil motor can be at least one code value, each voice coil motor is burnt with a step length parameter, the step length parameter represents each code value, and the voice coil motor can output the corresponding moving step length.
The execution main body can locally read or detect and acquire the step length parameter of the voice coil motor of the camera and the preset step length parameter of the preset voice coil motor, and then the execution main body can calculate the proportional relation between the step length parameter of the voice coil motor of the camera and the preset step length parameter according to the step length parameter of the voice coil motor of the camera and the preset step length parameter. The execution main body can obtain position adjustment information of the voice coil motor of the camera according to the proportional relation obtained through calculation and the movement data corresponding to the preset parameters.
As an example, the terminal may locally pre-store a preset step parameter and a mobile code value corresponding to the preset step parameter, and the terminal may adjust the preset voice coil motor according to the mobile code value, so that the camera focusing position is moved from the first position to the second position in the display screen by adjusting the preset voice coil motor. The terminal obtains the step length parameter of the voice coil motor of the camera by detecting the voice coil motor of the camera, compares the step length parameter of the voice coil motor of the camera with the preset step length parameter to obtain the ratio of the step length parameter of the voice coil motor of the camera to the preset step length parameter, and multiplies the ratio by the mobile code value corresponding to the preset step length parameter to obtain the mobile code value of the voice coil motor of the camera to serve as the position adjustment information.
In the implementation mode, based on the position adjustment information of the preset voice coil motor and the step length parameter of the voice coil motor, which are acquired in advance, the movement data corresponding to different voice coil motors can be automatically acquired, and the flexibility and the autonomy of the movement of the voice coil motor are improved.
In this step, the execution subject acquires a first image with a clear first position and a blurred second position and a second image with a blurred first position and a clear second position, and performs image synthesis on the first image and the second image by using an image synthesis technique to obtain an image with a clear first position and a clear second position.
With continuing reference to fig. 2, fig. 2 is a schematic diagram of one application scenario of the method of capturing images according to the present embodiment. In the application scenario of fig. 2, the terminal 201 captures an external picture through a camera, and displays a display picture in the view frame through a screen, where the display picture includes an upper half and a lower half, and the camera cannot focus on the upper half and the lower half at the same time. The terminal 201 receives the clicking operation of the user on the upper half part of the view frame, and controls the voice coil motor of the camera to move so that the camera focuses on the upper half part of the display picture. The terminal 201 receives a shooting operation performed by a user, and acquires a first image 202 acquired by focusing the upper half of the display picture by a camera, wherein the upper half of the first image 202 is clear but the lower half of the first image is fuzzy. When the terminal 201 reads a pre-acquired focusing position and moves from a first position to a second position in a display picture, the movement data of the voice coil motor is preset, the movement data that the voice coil motor of the camera needs to move is acquired according to the movement data of the voice coil motor, then the position of the voice coil motor of the camera is adjusted to enable the camera to focus on the lower half portion of the display picture, a second image 203 acquired by the camera focusing on the lower half portion of the display picture is acquired, and the lower half portion of the second image 203 is clear but the lower half portion is fuzzy. Finally, the terminal 201 performs image synthesis on the first image 202 and the second image 203 to generate an image 204 with clear upper and lower portions, and the image 204 is displayed through the screen of the terminal 201.
The method for shooting the image, provided by the embodiment of the disclosure, includes the steps of firstly obtaining a first image collected by a camera focusing a first position of a display frame in a viewing frame, adjusting the position of a voice coil motor of the camera to focus a second position in the display frame based on position adjustment information of preset voice coil motor movement data obtained in advance, obtaining movement second position data of the voice coil motor needing to be adjusted for focusing the second position of the display frame, and obtaining a second image collected by focusing the second position, wherein the position adjustment information of the preset voice coil motor comprises the movement data of the preset voice coil motor when the focusing position moves from the first position to the second position in the display frame, obtaining and generating images with clear first and second positions based on the first and second images, realizing rapid focusing, and not needing to respectively perform focusing operations twice on the display frame in the viewing frame, the focusing time is shortened, and the focusing efficiency and the shooting efficiency are improved.
In some optional implementations of the present embodiment, the preset position adjustment information of the voice coil motor may be obtained according to the following process 300:
in step 310, first position data of a preset voice coil motor at a first position in a camera focusing display picture is obtained.
In this step, the execution body may train a preset voice coil motor, and the preset voice coil motor is used to drive the camera, so that the camera may focus on a first position of a display frame in the view finder. When the executing body focuses on a first position in the display picture, first position data of the preset voice coil motor is obtained, where the first position data may be step length data, such as a code value, representing that the preset voice coil motor needs to move.
And 320, controlling the preset voice coil motor to move and determining the focusing position in the display picture corresponding to the preset voice coil motor when the preset voice coil motor moves to each preset position, taking the position data of the voice coil motor when the voice coil motor moves to the second position in the focusing display picture as second position data, and determining the position adjustment information of the preset voice coil motor based on the first position data and the second position data.
In this step, after the execution main body acquires the first position data based on the first position in the display frame focused by the camera, the preset voice coil motor is controlled to continuously move to different preset positions based on the first position data, for example, the preset voice coil motor is controlled to respectively move different code values based on the first position data, so that the preset voice coil motor reaches the preset position corresponding to each code value. The execution main body respectively determines the focusing position of the camera in the display picture when the preset voice coil motor moves to each preset position. The execution main body determines a focusing position which is a second position in the display picture by judging each focusing position, takes position data corresponding to the focusing position as second position data, and determines a difference value between the second position data and the first position data as preset position adjustment information of the voice coil motor.
As an example, after the terminal acquires the first position data, on the basis of the first position data, the terminal controls the preset voice coil motor to move by 1 code value, acquires a first focus position of the camera at the moment, then the terminal continues to control the preset voice coil motor to move by 1 code value, the position of the preset voice coil motor differs by 2 code values relative to the first position data at the moment, acquires a second focus position of the camera at the moment, and then the terminal continues to control the preset voice coil motor to move by 1 code value, the position of the preset voice coil motor differs by 3 code values relative to the first position data at the moment, and acquires a third focus position of the camera at the moment. The terminal can determine that the third focusing position is the second position in the focusing display picture from the first focusing position, the second focusing position and the third focusing position by comparing the first focusing position, the second focusing position and the third focusing position, and then the terminal moves the position data corresponding to the third focusing position, namely the position data corresponding to 3 code values on the basis of the first position data, and takes the position data as the second position data. Meanwhile, the terminal can acquire that the difference between the second position data of the preset voice coil motor and the first position data is 3 code values, and the obtained 3 code values are determined as the position adjustment information of the preset voice coil motor.
In this implementation, the voice coil motor is preset through control and is moved to different preset positions, so that the camera can focus different positions in the display picture, and the position adjustment information of the voice coil motor is preset when the camera focuses the preset positions can be determined from the position information, so that the position adjustment information is more accurate.
In some optional implementation manners of the present embodiment, the executing body determines a focusing position in a display screen corresponding to the preset voice coil motor when the preset voice coil motor moves to each preset position, and the method is implemented based on the following steps: the execution main body determines definition of a second position in an image collected when the preset voice coil motor moves to each preset position, and determines whether a focusing position in a corresponding display picture is the second position when the preset voice coil motor moves to each preset position based on the definition of the second position.
Specifically, the execution main body controls the preset voice coil motor to move continuously to different preset positions on the basis of the first position data, and obtains an image acquired after the camera is focused at each preset position, so as to obtain a plurality of images. The executing body may perform sharpness evaluation on the obtained multiple images through an image sharpness evaluation algorithm, or input the obtained multiple images into an image sharpness evaluation model to perform sharpness evaluation, so as to obtain sharpness of the second position in each image, analyze the sharpness of the second position in each image, determine whether the second position in each image is a focused position of the second position in the focused display screen, for example, analyze the sharpness of the second position in each image, determine an image with highest sharpness from the sharpness of the second position in each image, and determine the second position in the image as the focused position of the second position in the focused display screen.
As an example, after the terminal acquires the first position data, on the basis of the first position data, the terminal controls the preset voice coil motor to move by 1 code value, controls the preset voice coil motor to move to a first preset position, so that the camera focuses on the first preset position in the display picture, and acquires a first preset image acquired by the first preset position in the camera focusing display picture; then the terminal continuously controls the preset voice coil motor to move for 1 code value, controls the preset voice coil motor to move to a second preset position, enables the camera to focus on the second preset position in the display picture, and enables the position of the preset voice coil motor to have a difference of 2 code values relative to the first position data at the moment, and the terminal obtains a second preset image collected by the second preset position in the camera focusing display picture; and then the terminal continuously controls the preset voice coil motor to move 1 code value and controls the preset voice coil motor to move to a third preset position, so that the camera focuses on the third preset position in the display picture, the difference between the position of the preset voice coil motor and the first position data is 3 code values, and the terminal acquires a third preset image acquired by the camera focusing on the third preset position in the display picture. The terminal can evaluate the definition of the first preset image, the second preset image and the third preset image through an image definition evaluation algorithm to obtain the first definition of a second position in the first preset image, the second definition of the second position in the second preset image and the third definition of the second position in the third preset image. And the terminal sequences the first definition, the second definition and the third definition, determines the definition with the highest definition, and determines that the focusing position in the display picture corresponding to the image with the highest definition is the second position in the display picture.
In the implementation manner, the focusing position in the display picture is judged by comparing the definition of the second position in the plurality of images, so that the judgment of the focusing position in each image is more accurate, and the focusing position in the display picture determined based on the focusing position in the image is more accurate.
