Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
Before the shooting method provided by the embodiment of the application is introduced, slow synchronous flash portrait shooting in a professional single lens reflex camera is introduced. In professional flash portrait shooting, slow synchronous flash is often adopted, and a low shutter speed is combined with short flash, namely 'slow synchronous flash portrait shooting'. This flash mode is very useful in low light conditions to illuminate foreground subject while leaving the background area properly exposed. Since the exposure time of the flash is short, the shutter time more affects the brightness of the background in a longer shutter time, and the human body is mainly affected by the flash and less affected by the shutter time.
The time of opening the flash lamp is different from the time of opening and closing the shutter, so that the flash lamp is divided into front curtain synchronization and rear curtain synchronization. By utilizing the point, a shooting mode exists in the slow synchronous flash portrait shooting of professional single-lens reflex equipment: moving the camera while the rear curtain flashes synchronously, it is possible to make animated pictures of the person, clear and showing background light, also called "party figures", as they are often used in dance floors and parties. In the mobile terminal, limited by the brightness of a flash lamp and the opening mode of a shutter, when the mobile terminal is moved in the flash of the mobile terminal, a target person is blurred, and therefore the target person cannot be clearly shot.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Please refer to fig. 1, which is a flowchart illustrating a photographing method according to an embodiment of the present application. The method can be applied to electronic equipment, and the electronic equipment can be a mobile phone, a tablet computer, a notebook computer and the like. As shown in fig. 1, the method may include steps 1100-1300, which are described in detail below.
In this embodiment, the electronic device includes a camera application, and the shooting preview interface is an interface displayed after entering the camera application. Here, the camera application may be entered in different manners, for example, the user may click an icon of the camera application displayed on a display screen of the electronic device to enter a shooting preview interface of the camera application. For another example, the method may also be a method in which, during the process of running another application in the electronic device, the camera application is called through a camera call interface of the other application to enter a shooting preview interface of the camera application.
In this embodiment, when the shooting preview interface is displayed, the ambient brightness information of the first preview image displayed in the shooting preview interface is acquired, so as to determine whether the system time of the electronic device is in a day scene or a night scene according to the ambient brightness information.
And setting flash exposure information as flash exposure information of a flash lamp, wherein the set flash exposure information can be determined according to the recorded preview flash exposure value so as to meet the brightness requirement of normal supplementary lighting of the main subject in the first preview image.
Specifically, the brightness of the main object in the first preview image may be measured by flash pre-flash to meet the light supplement requirement for the main object, where the brightness of the main object in the first preview image measured by flash pre-flash is the above preview flash exposure value. For example, in the case where the preview flash exposure value is low, it indicates that the brightness of the subject object in the first preview image is low, and here, the flash exposure value of the flash may be set to be large. For another example, in the case where the preview flash exposure value is high, indicating that the brightness of the subject object in the first preview image is high, the flash exposure value of the flash may be set small.
In this embodiment, the step 1200 of capturing the first preview image according to the set flash exposure information to obtain the first image may further include the following steps 1210 to 1220:
step 1210, receiving a second input for the display preview interface.
The second input may be: the user may specifically determine the actual use requirement according to click input of the user on a shooting button in the shooting preview interface, or a voice instruction input by the user, or a specific gesture input by the user, which is not limited in the embodiment of the present application.
The specific gesture in the embodiment of the application can be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure identification gesture, a long-press gesture, an area change gesture, a double-press gesture and a double-click gesture; the click input in the embodiment of the application can be click input, double-click input, click input of any number of times and the like, and can also be long-time press input or short-time press input.
Step 1220, in response to the second input, shooting the first preview image according to the set flash exposure information to obtain a first image.
For example, after the user clicks a shooting button in the shooting preview interface, the electronic device may flash the first preview image with a flash according to the set flash exposure information to obtain the first image.
According to the above steps 1210-1220, the flash exposure information of the first image is determined by the preview flash exposure value, so that the requirement of normal supplementary lighting of the subject in the first preview image is satisfied.
In this embodiment, before the step 1100 is executed to acquire the ambient brightness information of the first preview image displayed in the shooting preview interface, the shooting method according to this embodiment may further include: and receiving a third input aiming at the shooting preview interface, responding to the third input, controlling the electronic equipment to enter a portrait shooting mode, and executing the step of acquiring the ambient brightness information of the first preview image displayed in the shooting preview interface under the condition that the electronic equipment enters the portrait shooting mode.
The third input may be a touch input for the capture preview interface, which may be a click input, which may be, for example, a single click input.
The photographing functions displayed in the photographing preview interface include, for example and without limitation: video function, shooting function, slow motion function, portrait function. Here, the third input may be an input of the user clicking a "portrait function". After the user clicks the portrait function, the portrait function of the electronic device can be opened.
After the first preview image is shot according to the set flash exposure information to obtain a first image, the method comprises the following steps:
in step 1300, a first input from a user is received.
The first input may be: the user shakes the input of the electronic device, which can be specifically determined according to actual use requirements, and the embodiment of the application is not limited thereto.
In this embodiment, after the first preview image is captured to obtain the first image according to the set flash exposure amount information, the prompt information is displayed in the capture preview interface, so that the photographer shakes the electronic device based on the prompt information.
As shown in fig. 2, after the first preview image is captured according to the set flash exposure information to obtain the first image, the capture preview interface displays a prompt message "please shake the mobile phone with the light", and the user can shake the electronic device based on the prompt message.
After receiving the first input of the user, entering:
step 1400, in response to the first input, obtaining shaking information of the electronic device, and obtaining a second image according to the environment brightness information and the shaking information.
In this embodiment, the second image is obtained in different manners according to different ambient brightness information. For example, in the daytime environment, the shutter speed is usually high, and a long shutter may cause overexposure of the picture, and for the daytime environment, the exposure of the second image does not depend on the ambient brightness information, but selects the background material from the preset background material library according to the shaking information of the user shaking the electronic device. For another example, for a night environment, the exposure of the second image captures a real smear effect according to the ambient brightness information and the user shaking information.
In one example, the step 1400 of obtaining shaking information of the electronic device in response to the first input and obtaining the second image according to the ambient brightness information and the shaking information may further include the following steps 1410a to 1430 a:
step 1410a, in response to the first input, obtaining a shaking direction and a shaking amplitude of the electronic device.
In this step 1410a, after the user shakes the electronic device, the shake direction and shake amplitude of the electronic device are determined according to the current tilt angle information of the electronic device detected by the gyroscope or the acceleration sensor inside the electronic device.
And 1420a, under the condition that the system time of the electronic equipment is determined to be in a first time period according to the environment brightness information, acquiring a preset background material library.
The preset background material library comprises materials with different directions of light smear, such as but not limited to background materials with 8 directions of east, south, west, north, northeast, southwest, northwest and southeast based on the shaking direction of the shooting behavior.
The system time may be the current time of the photographer's location. In specific implementation, the time zone in which the electronic device is located, that is, the time zone in which the photographer is located, may be determined according to the positioning information of the electronic device, and the corresponding time is obtained as the system time according to the time zone in which the photographer is located.
In this embodiment, a day may be divided into two time periods, the first time period may be a time period corresponding to the day, for example, 6:00 to 19:00, and the second time period may be a time period corresponding to the night. That is, in the case where it is determined that the current day environment is present according to the environment brightness information, the preset background material library is acquired.
And 1430a, obtaining the second image according to the shaking direction and the preset background material library under the condition that the shaking amplitude is within a set amplitude threshold range.
The set amplitude threshold value can be a numerical value set according to actual application scenes and actual requirements.
In this embodiment, under the condition that the shaking amplitude is within the set amplitude threshold range, a background material having the same direction as the shaking direction of the electronic device is selected from the preset background material library and is used as the second image. And then fusing the first image and the second image according to the subsequent steps to obtain a third image with dynamic effect.
According to the steps 1410a to 1430a, for the daytime environment, the exposure of the second image does not depend on the environment brightness information, but selects the background material from the preset background material library according to the shaking information of the user shaking the electronic device, so as to simulate the dynamic effect of the background shadow.
In one example, the step 1400 of obtaining shaking information of the electronic device in response to the first input and obtaining the second image according to the ambient brightness information and the shaking information may further include the following steps 1410b to 1430 b:
step 1410b, in response to the first input, obtaining a shaking amplitude of the electronic device.
In this step 1410b, after the user shakes the electronic device, the shake direction and shake amplitude of the electronic device are determined according to the current tilt angle information of the electronic device detected by the gyroscope or the acceleration sensor inside the electronic device.
And step 1420b, in the case that the system time of the electronic equipment is determined to be in the second time period according to the environment brightness information, determining the target exposure amount according to the environment brightness information.
The system time may be the current time of the photographer's location. In specific implementation, the time zone in which the electronic device is located, that is, the time zone in which the photographer is located, may be determined according to the positioning information of the electronic device, and the corresponding time is obtained as the system time according to the time zone in which the photographer is located.
In this embodiment, a day may be divided into two time periods, where the first time period may be a time period corresponding to the day, and the second time period may be a time period corresponding to the night, for example, 19:00 to 5: 00. That is, in the case where it is determined from the ambient brightness information that it is currently in the night environment, the trigger shutter is acquired to take a picture.
The exposure directly influences the brightness of a shot picture, the exposure is increased, the shot picture becomes dark, the exposure is reduced, and the shot picture becomes dark. There are three main factors affecting exposure: aperture, shutter speed and sensitivity, while for an electronic device the aperture is the real physical aperture, i.e. the clear aperture diameter of the lens, and thus the aperture is a fixed value, as shown in fig. 2, the aperture of the electronic device is f 8. In order to capture the second image with the best smear effect, the shutter speed and the sensitivity are usually adjusted to make the second image with the best smear effect.
The target exposure amount includes a target shutter speed and a target sensitivity, which are the shutter speed and the sensitivity that maximize the smear effect of the second image.
In step 1420b, the shutter speed and the sensitivity may be adjusted according to the ambient brightness information to obtain the target shutter speed and the target sensitivity, i.e. the target exposure.
And step 1430b, under the condition that the shaking amplitude is within a set amplitude threshold value range, shooting the second preview image according to the target exposure amount to obtain a second image.
The set amplitude can be a numerical value set according to an actual application scene and actual requirements.
In this step 1430b, when the shaking amplitude is within the set amplitude threshold range, the shutter is triggered to shoot the first preview image according to the target exposure amount, and a second image is obtained, so as to ensure a real smear effect.
According to the steps 1410b to 1430b, for the night environment, the exposure of the second image is based on the ambient brightness information and the shaking information of the electronic device, so that the real smear effect can be realized.
After responding to the first input, acquiring shaking information of the electronic equipment, and acquiring a second image according to the environment brightness information and the shaking information, entering:
and 1500, fusing the first image and the second image to obtain a third image.
In this embodiment, after the first image and the second image are obtained respectively, the first image and the second image may be fused to obtain a third image, which is the simulated "party portrait".
In this embodiment, the step 1500 of performing fusion processing on the first image and the second image to obtain a third image may further include the following steps 1510 to 1530:
step 1510, highlight extracting the second image to obtain a highlighted image.
In step 1510, the second image may be highlighted to obtain a highlighted image. The manner in which the second image is highlighted includes, but is not limited to, the rapid extraction manner of CTRL + ALT + 2.
Step 1520, performing fusion processing on the highlight image and the first image to obtain a fused image.
Step 1530, obtaining the third image according to the fused image and the first image.
In this embodiment, the obtaining the third image according to the fused image and the first image in step 1530 may further include: under the condition that the fused image comprises face information, identifying a target area where the face information is located in the fused image; carrying out contour segmentation processing on the target area in the fused image to obtain a segmented image; and obtaining the third image according to the segmentation image and the first image.
In this embodiment, under the condition that the fused image includes the face information, the contour segmentation processing is performed on the target area where the face information is located in the fused image according to the face outline segmentation information to obtain a segmented image, and then a third image is obtained according to the segmented image and the first image. The face information is protected, and the influence of ambient light smear is reduced.
According to the embodiment, the ambient brightness information of the first preview image displayed in the shooting preview interface is acquired, and meanwhile, the first preview image is shot according to the set flash exposure information to obtain the first image, namely the first image is shot according to the normal light supplementing requirement of the main object.
