Technical Field

You can focus twice on the inclined surface near and far, shoot two images, obtain clear images near and far, and then synthesize a clear image. Because it takes a long time to complete the two focusing based on the principle of contrast focusing, it takes a long time to complete the two focusing based on the principle of contrast focusing.

[0023] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant disclosure, rather than to limit the disclosure. It is also necessary to explain that, for ease of description, only the parts related to the relevant disclosure are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Continue to refer Figure 1 , shows a process 100 of an embodiment of a method for capturing an image according to the present disclosure. The method for capturing an image comprises the following steps:

[0026] Step 110, obtaining a first image captured at a first position of a display image in a focus frame of a camera.

[0027] In this step, the execution entity on which the method for capturing images is running may display a viewfinder on the screen, in which the picture captured by the camera may be displayed. The displayed picture in the viewfinder 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 the upper half of the picture in the viewfinder, and the picture corresponding to the second position may be the lower half of the picture in the viewfinder.

[0028] Optionally, the picture displayed in the viewfinder may include an inclined picture, or pictures at different positions, wherein the first position and the second position of the picture displayed in the viewfinder are respectively a position relatively close to the camera and a position relatively far from the camera in the inclined surface of the picture.

[0029] The execution subject displays the display image in the viewfinder on the screen, receives a click operation performed by the user on the first position in the display image, and controls the voice coil motor to move continuously based on the contrast focus principle, so that the camera focuses on the first position of the display image in the viewfinder, and the display image at the first position is clear. Based on the camera focusing on the first position, the execution subject obtains a first image captured by the camera focusing on the first position, and the first image includes an image image that is clear at the first position but blurred at the second position.

[0030] Step 120 , based on the pre-acquired position adjustment information of the preset voice coil motor, adjust the position of the voice coil motor of the camera so that the camera focuses on a second position in the display image, and obtain a second image captured by focusing on the second position.

[0031] In this step, after the execution subject obtains the first image with a clear first position in the display screen, the position adjustment information of the preset voice coil motor is obtained in advance. The position adjustment information can be used to adjust the position of the preset voice coil motor. The camera focuses on different positions by adjusting the position of the preset voice coil motor. The position adjustment information of the preset voice coil motor includes the movement data of the preset voice coil motor when the focus position moves from the first position in the display screen to the second position. After the execution subject obtains 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 the second position in the display screen, and then the second image captured by focusing on the second position is obtained, and the second image includes an image screen where the second position is clear but the first position is blurred.

[0032] In some optional implementations of this embodiment, the pre-acquired position adjustment information of the preset voice coil motor includes: movement data of the preset voice coil motor when the focus position corresponding to at least one preset step parameter of the preset voice coil motor moves from a first position in the display screen to a second position. The above-mentioned execution subject can obtain the step parameter of the voice coil motor of the camera, and determine the position adjustment information of the voice coil motor of the camera based on the proportional relationship between the step parameter of the voice coil motor of the camera and the preset step parameter, and the preset parameter corresponds to the movement data.

[0033] Specifically, the execution subject stores the position adjustment information of the preset voice coil motor in advance, and may store at least one preset step parameter, each of which corresponds to a movement data, and the movement data may be the movement data of the preset voice coil motor when the camera focus position moves from the first position in the display screen to the second position. The movement data corresponding to the preset voice coil motor may be at least one code value, and each voice coil motor is burned with its own step parameter, and the step parameter represents each code value, and the voice coil motor can output the corresponding movement step.

[0034] The execution subject can obtain the step length parameters of the voice coil motor of the camera and the preset step length parameters of the preset voice coil motor by local reading or detection, and then the execution subject can calculate the proportional relationship between the step length parameters of the voice coil motor of the camera and the preset step length parameters. The execution subject can obtain the position adjustment information of the voice coil motor of the camera based on the calculated proportional relationship and the movement data corresponding to the preset parameters.

[0035] As an example, the terminal can pre-store a preset step parameter and a movement code value corresponding to the preset step parameter locally. The terminal can adjust the preset voice coil motor according to the movement code value, and adjust the preset voice coil motor so that the camera focus position moves from the first position in the display screen to the second position. The terminal detects the voice coil motor of the camera to obtain the step parameter of the voice coil motor of the camera, compares the step parameter of the voice coil motor of the camera with the preset step parameter, obtains the ratio of the step parameter of the voice coil motor of the camera to the preset step parameter, and multiplies the ratio with the movement code value corresponding to the preset step parameter to obtain the movement code value of the voice coil motor of the camera as the position adjustment information.

[0036] In this implementation, based on the pre-acquired position adjustment information of the preset voice coil motor and the step size parameter of the voice coil motor, the movement data corresponding to different voice coil motors can be automatically acquired, thereby improving the flexibility and autonomy of the movement of the voice coil motor.

[0037] Step 130 , generating clear images of the first position and the second position based on the first image and the second image.

[0038] In this step, the execution entity obtains a first image in which the first position is clear but the second position is blurred, and a second image in which the first position is blurred but the second position is clear, and synthesizes the first image and the second image through image synthesis technology to obtain an image in which the first position and the second position are clear.

[0039] Continue to refer Figure 2 , Figure 2 FIG. 1 is a schematic diagram of an application scenario of the method for capturing an image according to this embodiment. Figure 2 In the application scenario, the terminal 201 captures the external image through the camera and displays the display image in the viewfinder through the screen. The display image includes the upper half and the lower half, and the camera cannot focus on the upper half and the lower half at the same time. The terminal 201 receives the user's click operation on the upper half of the viewfinder, controls the voice coil motor of the camera to move so that the camera focuses on the upper half of the display image. The terminal 201 receives the shooting operation performed by the user, obtains the first image 202 captured by the camera focusing on the upper half of the display image, and the upper half of the first image 202 is clear but the lower half is blurred. When the terminal 201 reads the pre-acquired focus position and moves from the first position in the display image to the second position, the movement data of the preset voice coil motor is preset, and the movement data that the voice coil motor of the camera needs to move is obtained according to the preset movement data of the voice coil motor, and then the position of the voice coil motor of the camera is adjusted so that the camera focuses on the lower half of the display image, and the second image 203 captured by the camera focusing on the lower half of the display image is obtained, and the lower half of the second image 203 is clear but the lower half is blurred. Finally, the terminal 201 synthesizes the first image 202 and the second image 203 to generate an image 204 with clear upper and lower halves, and displays the image 204 on the screen of the terminal 201 .

[0040] The method for shooting images provided by the embodiments of the present disclosure first obtains a first image captured by a camera at a first position of a display screen in a focus viewfinder, adjusts the position of a voice coil motor of the camera so that the camera focuses on a second position in the display screen based on position adjustment information of preset voice coil motor movement data that is obtained in advance, obtains the second position data of the voice coil motor that needs to be adjusted to focus on the second position of the display screen, and obtains a second image captured by focusing on the second position, wherein the position adjustment information of the preset voice coil motor includes the movement data of the preset voice coil motor when the focus position moves from the first position in the display screen to the second position, and based on the first image and the second image, generates clear images of the first position and the second position, thereby realizing fast focusing, eliminating the need to perform two focusing operations on the display screen in the viewfinder, thereby shortening the focusing time and improving the focusing efficiency and shooting efficiency.

[0041] In some optional implementations of this embodiment, the position adjustment information of the preset voice coil motor may be obtained according to the following process 300:

[0042] Step 310 , obtaining first position data of a preset voice coil motor at a first position in a camera focus display image.

[0043] In this step, the execution subject may train the preset voice coil motor and use the preset voice coil motor to drive the camera so that the camera can focus on the first position of the displayed image in the viewfinder. When the camera focuses on the first position in the displayed image, the execution subject obtains the first position data of the preset voice coil motor, which may be step data representing the step length that the preset voice coil motor needs to move, such as a code value.

[0044] Step 320, controlling the movement of the preset voice coil motor and determining the focus position in the display image corresponding to the preset voice coil motor when it moves to each preset position, taking the position data when the voice coil motor moves to the second position in the focus display image as the 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.

[0045] In this step, based on the first position in the camera focus display screen, after the execution subject obtains the first position data, based on the first position data, the preset voice coil motor is controlled to move continuously to different preset positions. For example, the preset voice coil motor is controlled to 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 subject determines the focus position of the camera in the display screen when the preset voice coil motor moves to each preset position. The execution subject determines that it is a focus position of the second position in the display screen by judging each focus position, and uses the position data corresponding to the focus position as the second position data, and determines the difference between the second position data and the first position data as the position adjustment information of the preset voice coil motor.

[0046] As an example, after the terminal obtains the first position data, based on the first position data, the preset voice coil motor is controlled to move by 1 code value to obtain the first focus position of the camera at this time, and then the terminal continues to control the preset voice coil motor to move by 1 code value. At this time, the position of the preset voice coil motor differs by 2 code values ​​relative to the first position data, and the second focus position of the camera at this time is obtained. Then the terminal continues to control the preset voice coil motor to move by 1 code value. At this time, the position of the preset voice coil motor differs by 3 code values ​​relative to the first position data, and the third focus position of the camera is obtained. The terminal can compare the first focus position, the second focus position, and the third focus position, and determine from the first focus position, the second focus position, and the third focus position that the third focus position is the second position in the focus display screen, then the position data corresponding to the third focus position, that is, the position data corresponding to the movement of 3 code values ​​based on the first position data, is used as the second position data. At the same time, the terminal can obtain that the second position data of the preset voice coil motor differs by 3 code values ​​relative to the first position data, and the obtained 3 code values ​​are determined as the position adjustment information of the preset voice coil motor.

[0047] In this implementation, by controlling the preset voice coil motor to move to different preset positions, the camera can focus on different positions in the display image, and the position adjustment information of the preset voice coil motor when the camera focuses on the preset position can be determined from multiple position information, making the position adjustment information more accurate.

[0048] In some optional implementations of the present embodiment, the above-mentioned execution subject determines the focus position in the display picture corresponding to the preset voice coil motor when it moves to each preset position, which is implemented based on the following steps: the above-mentioned execution subject determines the clarity of the second position in the image captured when the preset voice coil motor moves to each preset position, and determines whether the focus position in the display picture corresponding to the preset voice coil motor when it moves to each preset position is the second position based on the clarity of the second position.

[0049] Specifically, the execution subject controls the preset voice coil motor to move continuously to different preset positions based on the first position data, and obtains images captured after the camera focuses at each preset position to obtain multiple images. For example, the execution subject controls the preset voice coil motor to move different code values ​​based on the first position data. After moving the code value once, the camera focuses on a certain position in the display screen, and obtains the image captured at a certain position in the display screen when the camera focuses, thereby obtaining multiple images captured by the preset voice coil motor when it moves to each preset position. The above-mentioned execution entity can evaluate the clarity of the multiple acquired images through an image clarity evaluation algorithm, or input the multiple acquired images into an image clarity evaluation model for clarity evaluation to obtain the clarity of the second position in each image, and then analyze the clarity of the second position in each image to determine whether the second position in each image is the focus position of the second position in the focus display screen. For example, the clarity of the second position in each image is analyzed, and the image with the highest clarity is determined from the clarity of the second position in each image, and the second position in the image is determined as the focus position of the second position in the focus display screen.

[0050] As an example, after the terminal obtains the first position data, based on the first position data, the terminal first controls the preset voice coil motor to move by 1 code value, controls the preset voice coil motor to move to the first preset position, so that the camera focuses on the first preset position in the display screen, and the terminal obtains the first preset image captured at the first preset position in the display screen; then the terminal continues to control the preset voice coil motor to move by 1 code value, controls the preset voice coil motor to move to the second preset position, so that the camera focuses on the second preset position in the display screen, at this time, the position of the preset voice coil motor differs by 2 code values ​​relative to the first position data, and the terminal obtains the second preset image captured at the second preset position in the display screen; then the terminal continues to control the preset voice coil motor to move by 1 code value, controls the preset voice coil motor to move to the third preset position, so that the camera focuses on the third preset position in the display screen, at this time, the position of the preset voice coil motor differs by 3 code values ​​relative to the first position data, and the terminal obtains the third preset image captured at the third preset position in the display screen. The terminal can evaluate the clarity of the first preset image, the second preset image, and the third preset image through an image clarity evaluation algorithm to obtain a first clarity of the second position in the first preset image, a second clarity of the second position in the second preset image, and a third clarity of the second position in the third preset image. The terminal sorts the first clarity, the second clarity, and the third clarity to determine the clarity with the highest clarity, and determines that the focus position in the display screen corresponding to the image with the highest clarity is the second position in the display screen.

[0051] In this implementation, the focus position in the display screen is judged by comparing the clarity of the second position in multiple images, so that the judgment of the focus position in each image is more accurate, and thus the focus position in the display screen determined based on the focus position in the image is more accurate.
