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, described in detail below.
In this embodiment, the capture preview interface may be a capture preview interface of a camera application of the electronic device. The first preview image may be an image collected by a camera for a user to preview and view during a shooting preview process.
In this embodiment, the portrait information may be face information, body information, or body shadow information. Illustratively, the first preview image includes portrait information, and the first preview image may include face information, where the face information may be front face information or side face information. Illustratively, the first preview image includes portrait information, which may be that the first preview image includes portrait information. Illustratively, the first preview image includes portrait information, which may be that the first preview image includes human body shadow information.
The background information in the first preview image may be image information excluding portrait information in the first preview image. For example, sky information, building information, object information, and the like in the first preview image.
The second preview image has a silhouette effect, that is, the second preview image may highlight the image of the background information.
The preset photographing condition may be used to determine whether the first preview image can be processed into an image having a silhouette effect.
In this embodiment, in general, in a backlight environment, an image having a good silhouette portrait effect can be photographed. Based on this, a preset shooting condition may be set to determine whether the first preview image is suitable for processing as an image with silhouette effect according to the preset shooting condition. For example, it may be determined whether the background information of the first preview image satisfies a preset photographing condition according to the type of the background information in the first preview image, that is, an element included in the background information.
For example, whether the background information of the first preview image satisfies the preset photographing condition may be determined according to the degree of clutter of the background information of the first preview image. Specifically, under the condition that the clutter degree of the background information of the first preview image is low, it is described that the background of the first preview image is relatively neat, and when the silhouette is processed, the background information does not interfere with the portrait information, and then the background information of the first preview image is considered to meet the preset shooting condition. Under the condition that the background information of the first preview image is high in disorder degree, the background information interferes with the portrait information when the silhouette portrait is processed, and the background information of the first preview image is considered not to meet the preset shooting condition.
For example, whether the background information of the first preview image satisfies the preset shooting condition may be determined according to the clutter degree of the elements and the background information included in the background information of the first preview image. For example, when the background information of the first preview image includes a sky element and the background information is low in clutter, it is described that the shooting environment may be a backlight shooting environment, and the background of the first preview image is neat and suitable for silhouette processing, and it is considered that the background information of the first preview image satisfies the preset shooting condition. When the background information of the first preview image contains more scene elements, the portrait part cannot be highlighted during silhouette portrait processing, and the silhouette portrait processing is not suitable, and the background information of the first preview image is considered not to meet the preset shooting condition.
The following examples are given by way of illustration.
In some embodiments of the present application, processing the first preview image to obtain a second preview image with silhouette effect when the background information meets a preset shooting condition may further include: processing the first preview image according to a preset exposure parameter under the condition that the background information is a first type of background and meets a first preset condition to obtain a second preview image with a silhouette portrait effect; the first type background comprises a first element, and the display area occupation ratio of the first element in the first preview image is larger than or equal to a first threshold value.
In this embodiment, the first type of background may be a background that includes the first element and has a display area ratio of the first element in the first preview image that is greater than a first threshold. The first element may be sky. E.g. a blue sky, a cloudy sky, a sky with a canyon. In a specific implementation, it may be detected, by the scene detection model, whether the background information of the first preview image is a first type of background. It should be noted that, under the condition that the ambient light intensity is relatively high, an overexposed area may appear in the captured first preview image, and based on this, when the overexposed area is included in the first preview image, it is determined that the background information of the first preview image is the first type of background.
The first threshold may be used to measure the occupancy of the first element in the picture. Illustratively, the first threshold may be that a display area of the sky is greater than or equal to 1/3 in the first preview image. It should be noted that the first threshold may be set according to actual requirements, which is not limited in this embodiment of the application.
The first preset condition can be used for measuring whether the clutter degree of the background information meets the requirement. Under the condition that the background information meets the first preset condition, the background of the first preview image is relatively simple, and the second preview image with the silhouette effect can be directly generated. When the background information does not satisfy the first preset condition, the background of the first preview image is messy, and the second preview image with the silhouette effect cannot be directly generated.
In an alternative embodiment, a background object in the first preview image may be identified, and a depth information image of the first preview image is acquired; and determining whether the background information of the first preview image meets a first preset condition or not according to the background object included in the first preview image and the depth information image of the first preview image.
In this embodiment, background objects of different depths in the depth information image of the first preview image are different in shade of color. The closer the background object is to the portrait, the darker the color, and the further the background object is from the portrait, the lighter the color. That is, the degree of clutter of the background information can be determined from the depth information image of the first preview image. Meanwhile, by recognizing the first preview image, the degree of disorder of the background information can be determined from the recognized background object. Based on this, whether the background information of the first preview image meets a first preset condition is determined according to the background object included in the first preview image and the depth information image of the first preview image. For example, in the depth information image of the first preview image, if the colors around the portrait are relatively uniform, the background information of the first preview image is considered to meet the first preset condition. For example, if the background information of the first preview image does not include a background object having a specific shape, the background information of the first preview image is considered to meet the first preset condition.
In this embodiment, the first preview image is processed according to a preset exposure parameter, which may be to reduce the overall exposure, so that the brightness of the first preview image is reduced to obtain a second preview image with silhouette effect.
In this embodiment, when the background information is the first type of background and the background information meets the first preset condition, the exposure parameter is adjusted, and the second preview image with the silhouette portrait effect can be directly generated without the user processing the background information by means of professional image processing software, so that the operation is simple, and the shooting efficiency can be improved.
In some embodiments of the present application, processing the first preview image to obtain a second preview image with silhouette effect when the background information meets a preset shooting condition may further include: under the condition that the background information is a first-class background and does not meet a first preset condition, identifying a second element in the background information, wherein the second element is an element except the first element in the background information; and under the condition that the second element is located in the first area of the first preview image, processing the first preview image according to preset exposure parameters and a preset shooting angle to obtain a second preview image with a silhouette effect.
In this embodiment, the first type of background may be a background that includes the first element and has a display area ratio of the first element in the first preview image that is greater than a first threshold. The first element may be sky. The second element may be a background element other than the first element. Such as buildings, people, natural landscapes, etc.
Illustratively, the first area may be an area located below the first preview image screen. The first region may also be a region located below the portrait in the first preview image.
In this embodiment, when the background information is the first type of background and the background information does not satisfy the first preset condition, it is described that the background information belongs to a backlight environment in which a silhouette effect can be captured, but the background information is relatively messy. Further, it may be determined whether a second element in the background information is located in the first area of the first preview image to determine whether the second element of the background information may be avoided by adjusting the photographing angle. If the second element is located in the first area of the first preview image, the shooting angle can be adjusted to avoid the disordered part of background information in the first preview image.
Take the first preview image shown in fig. 2 as an example. Specifically, as shown in fig. 2, the first preview image has a sky displayed in a ratio exceeding 1/3 of the screen, and belongs to the first type background. The first preview image includes portrait information 201 therein. The background information of the first preview image also includes cluttered background people 202. It can be seen that the background crowd 202 is located below the portrait information 201, that is, the second element in the background information is located in the first area in the first preview image. At this time, a photographing angle of the electronic device may be adjusted such that only the sky portion is included in the background information of the first preview image. And finally, adjusting exposure parameters to shoot to obtain a second preview image with a silhouette portrait effect.
In this embodiment, when the background information is a first-class background and the background information does not satisfy a first preset condition, a position of a second element in the background information in the first preview image may be determined, and when the second element is located in a first area in the first preview image, the first preview image may be processed according to a preset exposure parameter and a preset shooting angle to obtain a second preview image with a silhouette effect. In addition, the embodiment can also improve the success rate of shooting.
In some embodiments of the present application, processing the first preview image to obtain a second preview image with silhouette effect when the background information meets a preset shooting condition may further include: processing a second area in the first preview image under the condition that the background information is a second type of background to obtain a second preview image with a silhouette effect; the second area is an area containing the portrait information in the first preview image.
In this embodiment, the second type of background may be a single background scene. For example, fig. 3 shows a building background 301 of a single frame construction. Also for example, fig. 4 shows a light-colored wall surface 401.
In this embodiment, although the description of the capturing background of the first preview image is simple when the background information is the second type of background, the capturing environment does not belong to the backlight environment, and the second preview image having the silhouette effect cannot be obtained by adjusting the exposure parameters. At this time, the first preview image may be processed using image processing techniques to obtain a second preview image having silhouette portrait effect.
Illustratively, the first preview image is segmented by using a portrait segmentation technology to obtain a second area containing portrait information, and the second area is processed to obtain a second preview image with silhouette portrait effect.
In this embodiment, when the background information of the first preview image is the second type of background, the first preview image may be processed based on an image processing technology to obtain the second preview image with the silhouette effect, so that the second preview image with the silhouette effect may be obtained by processing the first preview image without depending on an external shooting environment. And when the background information of the first preview image is the first type of background, a second preview image with silhouette portrait effect can be obtained by directly shooting through adjusting exposure parameters. In this embodiment, a plurality of modes of generating the image with the silhouette portrait effect are provided, and the image with the silhouette portrait effect can be shot in different shooting scenes, so that the shooting mode is more flexible, and the user experience is better.
In some embodiments of the present application, a prompt identifier is displayed when the background information meets a preset shooting condition.
In this embodiment, the prompt identifier can be used for prompting the user to perform silhouette portrait processing on the first preview image, so that the user can be reminded that the current shooting effect is the silhouette portrait shooting effect, the user can switch the common shooting mode and the silhouette portrait shooting mode according to actual needs, and user experience is better.
In some embodiments of the present application, after the processing the first preview image to obtain the second preview image with silhouette effect, the method may further include: acquiring shooting scene information corresponding to the shooting preview interface; adjusting display parameters of the second preview image according to the shooting scene information; wherein the display parameters include at least one of: color temperature, hue, brightness and saturation.
In the present embodiment, the shooting scene information may be, for example, the seaside sky, the sky below sunset, or the like. In a specific implementation, the shooting scene information of the first preview image can be identified through the AI scene identification model.
The display parameters may include color temperature, hue, brightness, saturation, and the like. Different shooting scene information corresponds to different shooting parameters. For example, when the shooting scene information is the sky under sunset, the color temperature can be adjusted to-300, the saturation of yellow, orange, red and purple is +20, and the color of Cabernet is highlighted to make the sense of warmth of sunset. Also for example, when the shooting scene information is a seaside sky, the color temperature may be adjusted to +300, and the saturation of blue and green may be adjusted to +20, so as to enhance the vividness of the seaside sky and the sea water color.
In this embodiment, after the first preview image is processed to obtain the second preview image with silhouette effect, the display parameters of the second preview image may be further adjusted according to the shooting scene information to improve the display effect of the second preview image.
In some embodiments of the present application, after the processing the first preview image to obtain the second preview image with silhouette effect, the method may further include: receiving a first input of a user; and outputting the target image based on the screen content of the second preview image in response to the first input.
The first input may be an input for capturing a target image. Illustratively, the first input may be a click input of a target control of the shooting preview interface by a user, or a voice input by the user, or a specific gesture input by the user, which may be determined according to actual use requirements, and is not limited in this embodiment of the application.
The specific gesture in the embodiment of the application can be any one of a single-click gesture, a sliding gesture and a dragging 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.
