Description

Technical Field

[0001] This application belongs to the field of image processing technology, specifically relating to a shooting method and apparatus. Background Technology

[0002] Using the camera to record life has become one of the main uses of mobile devices such as smartphones, and architectural scenes account for a very high proportion of daily photography. When a photographer is standing on the ground and shooting a target building, if they are close to the building, they need to raise their phone to shoot from a low angle to capture the entire building. When shooting from a low angle, the camera's imaging plane will form a certain angle with the side facade of the building, thus producing a perspective distortion effect. That is, the originally vertical lines of the building will appear to converge upwards and lean backwards, making it impossible to present the original vertical shape of the building.

[0003] In related technologies, in order to make the originally vertical buildings in the image appear vertical, the horizon camera mode is usually used to shoot, so as to perform perspective correction on the vertical buildings.

[0004] However, if the phone is tilted beyond a certain pitch angle when shooting in horizon mode, the field of view of the resulting image will be small, failing to retain much of the scene and resulting in poor photo quality. Summary of the Invention

[0005] The purpose of this application is to provide a shooting method and apparatus that can solve the problem of poor photo quality.

[0006] In a first aspect, embodiments of this application provide a shooting method, including:

[0007] When the shooting mode is entered, a first preview image is displayed in the first area and a first target image is displayed in the second area. The first target image is a corrected version of the first preview image, and the acquisition angle of the preview image is positively correlated with the size of the first area.

[0008] Receive the first input;

[0009] In response to the first input, the size of the first region is adjusted, a second preview image after the acquisition viewpoint adjustment is displayed in the first region, and a second target image is displayed in the second region, wherein the second target image is the image after the second preview image is corrected;

[0010] Receive camera input;

[0011] In response to the shooting input, capture and store the image of the second target.

[0012] Secondly, embodiments of this application provide a shooting device, including:

[0013] The first display module is used to display a first preview image in a first area and a first target image in a second area when entering the shooting mode. The first target image is a corrected version of the first preview image, and the acquisition angle of the preview image is positively correlated with the size of the first area.

[0014] The first receiving module is used to receive the first input;

[0015] The second display module is used to adjust the size of the first area in response to the first input, display the second preview image after the acquisition viewpoint is adjusted in the first area, and display the second target image in the second area, wherein the second target image is the image after the second preview image is corrected;

[0016] The second receiving module is used to receive shooting input;

[0017] The imaging module is used to capture and store a second target image in response to an imaging input.

[0018] Thirdly, embodiments of this application provide an electronic device including a processor and a memory, wherein the memory stores a program or instructions executable on the processor, and the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0019] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0020] Fifthly, embodiments of this application provide a chip including a processor and a communication interface, wherein the communication interface is coupled to the processor, and the processor is used to run programs or instructions to implement the steps of the method described in the first aspect.

[0021] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, the program product being executed by at least one processor to implement the steps of the method described in the first aspect.

[0022] In this embodiment, when entering shooting mode, a first preview image is displayed in a first area, and a first target image is displayed in a second area. The first target image is a corrected version of the first preview image, and the acquisition angle of the preview image is positively correlated with the size of the first area. A first input is received; in response to the first input, the size of the first area is adjusted, and a second preview image with the adjusted acquisition angle is displayed in the first area, while a second target image is displayed in the second area. The second target image is a corrected version of the second preview image. A shooting input is received; in response to the shooting input, the second target image is captured and stored. Thus, when the size of the first area increases, the field of view of the electronic device's camera increases, and the image acquisition range of the camera increases, resulting in a larger field of view for the final image. This allows for the retention of more content in the shooting scene, improving photo quality. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The following description, in conjunction with the accompanying drawings, details the imaging method and apparatus provided in this application through specific embodiments and application scenarios.

[0035] Figure 1 This is a schematic flowchart of the shooting method provided in an embodiment of this application. The shooting method may include:

[0036] Step 101: When entering shooting mode, display a first preview image in the first area and a first target image in the second area, wherein the first target image is a corrected version of the first preview image, and the acquisition angle of the preview image is positively correlated with the size of the first area.

[0037] In some possible implementations of the embodiments of this application, the shooting mode in the embodiments of this application can be a horizon shooting mode, wherein the horizon shooting mode is a photography mode in which the image displayed in the second area remains horizontal relative to the horizon. The target image is the image obtained after correcting the preview image using the image correction algorithm corresponding to the horizon shooting mode. The embodiments of this application do not elaborate on the process of correcting the preview image using the image correction algorithm; for details, please refer to the correction process in related technologies.

[0038] The positive correlation between the acquisition angle of the preview image and the size of the first region means that the acquisition angle of the preview image increases as the size of the first region increases, and decreases as the size of the first region decreases.

[0039] In some possible implementations of the embodiments of this application, the first region and the second region can be regions on the screen in shooting mode.

[0040] For example, such as Figure 2a As shown. Figure 2a This is a schematic diagram illustrating the display of a first preview image and a first target image provided in an embodiment of this application. Figure 2a In the first region 21, a first preview image 201 is displayed, and in the second region 22, a first target image 211 is displayed.

[0041] Step 102: Receive the first input.

[0042] In some possible implementations of the embodiments of this application, the first input in the embodiments of this application is used to adjust the size of the first area. Exemplarily, the first input includes, but is not limited to: touch input from a user via a touch device such as a finger or stylus to a control for adjusting the size of the first area, or a voice command input by the user, or a specific gesture input by the user, or other feasible inputs. The specific input can be determined according to actual usage needs, and the embodiments of this application do not limit this. For example, the first input can be a click input from the user on a control displayed on the first area for adjusting the size of the first area.

[0043] In some possible implementations of this application, when the first input is a touch input from a user to a control used to adjust the size of the first area via a touch device such as a finger or stylus, step 102 may include: receiving touch input to the first control, which is used to adjust the size of the first area.

[0044] In some possible implementations of the embodiments of this application, the first control in the embodiments of this application may be an addition or subtraction control.

[0045] In some possible implementations of embodiments of this application, step 102 may include: receiving drag input on the border of the first region.

[0046] In this embodiment of the application, the size of the first region can be adjusted by dragging the border of the first region.

[0047] Step 103: In response to the first input, adjust the size of the first region, display the second preview image after the acquisition viewpoint adjustment in the first region, and display the second target image in the second region, wherein the second target image is the image after the second preview image is corrected.

[0048] When the size of the first area is adjusted, the field of view of the camera in the electronic device changes, the image acquisition range of the camera changes, and consequently, the images displayed in the first and second areas also change. For example... Figure 2b As shown, Figure 2b This diagram illustrates the images displayed in the first and second regions after the first region has been resized. Figure 2bIn the first region 21, a second preview image 202 is displayed, and in the second region 22, a second target image 212 is displayed.

[0049] Step 104: Receive shooting input.

[0050] In some possible implementations of the embodiments of this application, the shooting input in the embodiments of this application is used for shooting and storing images. Exemplarily, the shooting input includes, but is not limited to: touch input by the user via a touch device such as a finger or stylus to controls used for shooting and storing images, or voice commands input by the user, or specific gestures input by the user, or other feasible inputs. The specific input can be determined according to actual usage needs, and the embodiments of this application do not limit this. For example, the shooting input can be a click input by the user on controls displayed on the first area for shooting and storing images.

[0051] Step 105: In response to the shooting input, capture and store the second target image.

[0052] In this embodiment, when entering shooting mode, a first preview image is displayed in a first area, and a first target image is displayed in a second area. The first target image is a corrected version of the first preview image. The acquisition angle of the preview image is positively correlated with the size of the first area. The first and second areas are areas on the screen in shooting mode. A first input is received. In response to the first input, the size of the first area is adjusted, and a second preview image with the adjusted acquisition angle is displayed in the first area. A second target image is displayed in the second area, and the second target image is a corrected version of the second preview image. A shooting input is received. In response to the shooting input, the second target image is captured and stored. Thus, when the size of the first area increases, the field of view of the electronic device's camera increases, and the image acquisition range of the camera increases, resulting in a larger field of view for the final image. This allows more content in the shooting scene to be retained, improving photo quality.

[0053] In some possible implementations of the embodiments of this application, when taking a picture using the horizon shooting mode, the preview image is usually cropped using the center cropping method. Then, the cropped image is input into the image correction algorithm corresponding to the horizon shooting mode to obtain an image that remains horizontal relative to the horizon.

[0054] For example, such as Figure 3 As shown, Figure 3 This is a schematic diagram of a center-cropped image provided in an embodiment of this application. Figure 3 In the image, the aspect ratio of the center-cropped image is y:x, where the aspect ratio can be set according to actual needs. Let the center-cropped size be 2x * 2y. Then in... Figure 3In, EF=BD-y=EG+GF, EG=1 / 2*AB*tan∠BAC, GF=x*tan∠BAC, then:

[0055] y=BD-1 / 2*AB*tan∠BAC)-x tan∠BAC.

[0056] Where EF is the distance between points E and F, BD is the distance between points B and D, EG is the distance between points E and G, GF is the distance between points G and F, EG is the distance between points E and G, AB is the distance between points A and B, tan is the tangent, ∠BAC is the angle between sides BA and CA, x is half the height of the cutting dimension, and y is half the width of the cutting dimension.

[0057] When BD increases, AB, ∠BAC, and x remain unchanged, while y increases as BD increases. Consequently, the image size input into the image conversion algorithm corresponding to the horizon shooting mode increases. With the perspective correction angle remaining unchanged, the field of view of the final image increases, allowing more content from the shooting scene to be retained in the photo, thus improving photo quality.

[0058] In some possible implementations of the embodiments of this application, the second region includes a second control, which is used to adjust the tilt angle of the second target image relative to the horizon; after step 103 and before step 104, the shooting method provided in the embodiments of this application may further include: receiving a second input to the second control; in response to the second input, displaying a third target image in the second region, wherein the third target image is an image obtained by adjusting the second target image with the tilt angle corresponding to the second input.

[0059] In some possible implementations of the embodiments of this application, the second control in the embodiments of this application can be a scroll bar control. Accordingly, the second input in the embodiments of this application is the user's drag input of the scroll bar slider of the scroll bar control through a touch device such as a finger or stylus.

[0060] For example, such as Figure 4a and Figure 4b As shown. Figure 4a The image shown in the second area before the tilt angle was adjusted is displayed. Figure 4b The image displayed in the second region after tilt angle adjustment is shown. Specifically, before tilt angle adjustment, a second target image 212 is displayed in the second region 22. When the scroll bar slider 401 of the scroll bar 40 is dragged, the tilt angle is adjusted, and a third target image 213 is displayed in the second region 22 after tilt angle adjustment. Figure 4a and Figure 4bIn the middle, the scroll bar 40 includes two moving bars, namely scroll bar X and scroll bar Y. Scroll bar X is used to adjust the tilt angle of the second target image relative to the horizon, and scroll bar Y is used to adjust the tilt angle of the second target image relative to the vertical line of the horizon.

[0061] In some possible implementations of the embodiments of this application, in the initial state, the scroll bar slider can be located in the middle position of the scroll bar control. When the slider of scroll bar X is dragged to the right, the image to the left of the vertical center line of the second target image shifts to the right, and the image to the right of the vertical center line shifts to the left; when the slider of scroll bar X is dragged to the left, the image to the left of the vertical center line of the second target image shifts to the left, and the image to the right of the vertical center line shifts to the right; when the slider of scroll bar Y is dragged to the right, the image above the horizontal center line of the second target image shifts downward, and the image below the horizontal center line shifts upward; when the slider of scroll bar Y is dragged to the left, the image above the horizontal center line of the second target image shifts upward, and the image below the horizontal center line shifts downward.

[0062] In some possible implementations of this application's embodiments, after adjusting the tilt angle of the second target image, the third target image displayed in the second area may differ significantly from the second preview image. In this case, relying solely on image cropping in horizon photography mode may reduce image quality. Therefore, after step 103, the shooting method provided in this application's embodiments may further include: displaying a prompt message corresponding to the tilt angle in the first area, wherein the prompt message is used to prompt adjustment of the electronic device's movement direction.

[0063] For example, when the scroll bar slider is dragged to the right to 1°, the image to the left of the center line of the second target image shifts 1° to the right, and the image to the right of the center line shifts 1° to the left. Simultaneously, a prompt message corresponding to +1° is displayed in the first area. When the scroll bar slider is dragged to the left to 1°, the image to the left of the center line of the second target image shifts 1° to the left, and the image to the right of the center line shifts 1° to the right. Simultaneously, a prompt message corresponding to -1° is displayed in the first area. For example, the prompt message corresponding to +1° is "Please move the electronic device upwards," and the prompt message corresponding to -1° is "Please move the electronic device downwards."

[0064] It should be noted that the prompts for each tilt angle can be set according to actual needs.

[0065] In this embodiment of the application, by displaying prompt information corresponding to the tilt angle to guide the user to adjust the movement direction of the electronic device, the electronic device can reach a new position to capture images. This can achieve image correction in horizon shooting mode with minimal loss of image quality, resulting in better shooting effects.

[0066] In some possible implementations of the embodiments of this application, the shooting method provided in the embodiments of this application may further include: storing a second preview image; upon receiving a third input to edit the second preview image, in response to the third input, displaying the second preview image in a third area, displaying a fourth target image and a third control in a fourth area, wherein the fourth target image is a corrected version of the second preview image, and the third control is used to adjust the tilt angle of the fourth target image relative to the horizon; receiving a fourth input to the third control; in response to the fourth input, displaying a fifth target image in the fourth area, wherein the fifth target image is an image obtained by adjusting the fourth target image with the tilt angle corresponding to the fourth input; receiving a fifth input; and in response to the fifth input, storing the fifth target image.

[0067] In some possible implementations of the embodiments of this application, the second target image can be stored at the same time as the second preview image after receiving the shooting input, or the second preview image can be stored after the second target image is stored, or the second preview image can be stored after receiving the input for storing the second preview image.

[0068] In some possible implementations of the embodiments of this application, the third input provided in the embodiments of this application is used to initiate an image editing mode. Exemplarily, the third input includes, but is not limited to: touch input by the user via a touch device such as a finger or stylus to the control used to initiate the image editing mode, or a voice command input by the user, or a specific gesture input by the user, or other feasible inputs. The specific input can be determined according to actual usage needs, and the embodiments of this application do not limit this. For example, the third input can be the user's click input on the editing control corresponding to the second preview image stored in the album.

[0069] In some possible implementations of the embodiments of this application, the third region and the fourth region can be regions on the screen in image editing mode.

[0070] In some possible implementations of the embodiments of this application, the third control in the embodiments of this application can be a scroll bar control. Correspondingly, the fourth input in the embodiments of this application is the user's drag input of the scroll bar slider of the scroll bar control through a touch device such as a finger or stylus.

[0071] The process of adjusting the tilt angle of the fourth target image displayed in the fourth area by the fourth input of the third control is similar to the process of adjusting the tilt angle of the second target image by the second input of the second control. For details, please refer to the above process. This application embodiment will not be described in detail here.

[0072] In some possible implementations of the embodiments of this application, the fifth input provided in the embodiments of this application is used to save a fifth target image. Exemplarily, the fifth input includes, but is not limited to: touch input by the user via a touch device such as a finger or stylus to the control used to save the fifth target image, or a voice command input by the user, or a specific gesture input by the user, or other feasible inputs. The specific input can be determined according to actual usage needs, and the embodiments of this application do not limit this. For example, the fifth input can be a click input by the user on the control displayed in the image editing interface for saving the fifth target image, wherein the control used to save the fifth target image can be a completion button or a save button, etc.

[0073] For example, in the photo album, the user first selects a second preview image. Then, when the user clicks the image editing control, the second preview image is displayed in the third area, and the fourth target image (i.e., the image after the second preview image is corrected) and the scroll bar control are displayed in the fourth area. When the user drags the scroll bar slider of the scroll bar control, the fifth target image obtained by adjusting the tilt angle corresponding to the scroll bar slider drag is displayed in the fourth area. When the user clicks the finish control, the fifth target image is saved.

[0074] In this embodiment of the application, the user can perform secondary editing on the second preview image to obtain an image that meets the user's needs.

[0075] The shooting method provided in this application can be executed by a shooting device. This application uses a shooting device executing the shooting method as an example to illustrate the shooting device provided in this application.

A first input is received; in response to the first input, the size of the first area is adjusted, and a second preview image with the adjusted acquisition angle is displayed in the first area, while a second target image is displayed in the second area. The second target image is a corrected version of the second preview image. A shooting input is received; in response to the shooting input, the second target image is captured and stored. Thus, when the size of the first area increases, the field of view of the electronic device's camera increases, and the image acquisition range of the camera increases, resulting in a larger field of view for the final image. This allows for the retention of more content in the shooting scene, improving photo quality.
