Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods of some embodiments of the present disclosure.

The embodiment of the disclosure provides an image shooting method which is applied to a terminal. According to the method, after the original preview image is determined according to the first preview image acquired by the first camera unit and the second preview image acquired by the second camera unit, the original preview image can be adjusted to obtain a more coordinated and real overall target preview image, the image shooting effect is improved, and the use experience of a user is improved.

In one exemplary embodiment, an image photographing method is provided, which is applied to a terminal. Referring to fig. 1, the method may include:

S110, determining an original preview image according to a first preview image acquired by a first camera unit and a second preview image acquired by a second camera unit;

s120, adjusting the original preview image to determine a target preview image.

In step S110, the terminal includes an image capturing component, which may be a dual-image capturing component or a multi-image capturing component, which is not limited thereto. The camera assembly may include a first camera unit and a second camera unit. When the camera shooting assembly is a double camera shooting assembly, the first camera shooting unit can be a front camera shooting unit, and correspondingly, the second camera shooting unit can be a rear camera shooting unit; or the first camera unit may be a rear camera unit, and correspondingly, the second camera unit may be a front camera unit; this is not limited thereto.

In the step, after a camera shooting assembly of a terminal is started, a first camera shooting unit in the camera shooting assembly can acquire images, so that a first preview image is obtained; in addition, the second image capturing unit may also perform image capturing, so as to obtain a second preview image. After the first preview image and the second preview image are determined, the original preview image may be determined from the first preview image and the second preview image.

Wherein a partial image may be selected from the first preview image and then combined with the second preview image, thereby obtaining an original preview image having both the partial image and the second preview image. And the detail image of the second preview image and the first preview image can be synthesized, so that the original preview image with optimized details can be obtained. It should be noted that, in addition to the above manner, the method may also determine the original preview image in other manners, which is not limited thereto.

In addition, before the first preview image and the second preview image are acquired, in the method, the light information of the shooting environment can be detected through the photosensitive unit of the terminal, and then the light information is transmitted to the processor of the terminal, so that the processor acquires the light information of the shooting environment. The light information may include information of the position of the light source relative to the terminal, or may include information of the brightness of the light, or may include other light information, which is not limited.

After the terminal determines the light information, the flash lamp of the terminal can be controlled to perform corresponding light supplementing treatment according to the position information of the light source relative to the terminal in the light information and the brightness information of the light, so that a first preview image and a second preview image with better effects are obtained.

The light sensing unit may be a light sensor, an image capturing unit, or other devices capable of detecting light information in the shooting environment, which is not limited.

In addition, after the original preview image is determined, the original preview image can be displayed on a preview interface so that a user can know the image effect of the original preview image. When the terminal includes a display interface, the display interface may be determined as a preview interface. When the terminal includes at least two display interfaces (for example, the terminal may be a folding screen mobile phone), a display interface facing the user from among the at least two display interfaces may be determined as a preview interface, so that the user can observe an original preview image displayed in the preview interface.

In step S120, the original preview image includes content belonging to the first preview image, which may be denoted as first preview content, and also includes content belonging to the second preview image, which is denoted as second preview content. In this step, the first preview content and/or the second preview content of the original preview image may be adjusted according to the image information (including the brightness information) of the first preview content and the image information of the second preview content, so as to obtain a target preview image with a more balanced overall effect. The target preview image comprises adjusted first preview content and second preview content.

The difference value of the brightness of at least the edges of the first sub-image and the second preview image can be limited within a preset threshold range by adjusting the light parameters. The light parameters may include a flash lamp parameter corresponding to the first camera unit, a flash lamp parameter corresponding to the second camera unit, a brightness parameter of a display screen of the terminal, and the like, and of course, may also include other parameters capable of adjusting light in a shooting environment, which is not limited.

For example, if the user observes that the brightness of the first preview content is darker than the brightness of the second preview content in the original preview image, the brightness of the first sub-image and/or the brightness of the second preview image can be adjusted by adjusting the flash parameters corresponding to the first image capturing unit, so that the difference between the brightness of at least the edges of the first sub-image and the brightness of the second preview image is less than or equal to a preset threshold (for example, 10 candelas per square meter (cd/m 2)), thereby realizing the adjustment of the original preview image and obtaining the target preview image with better image effect.

Of course, besides the shooting light parameters, the original preview image can be adjusted by directly adjusting the contrast or brightness of the first sub-image and the second preview image, so that the whole effect of the original preview image is more coordinated, and the phenomenon that the picture at the splicing position of the first sub-image and the second preview image is too abrupt is avoided.

For example, if the user observes that the difference of the picture contrast between the splicing position of the first preview content and the second preview content in the original preview image is too large, the contrast between the first sub-image and the second preview image can be reduced by adjusting the contrast between the first sub-image and/or the second preview image, so that the original preview image is more coordinated, and a target preview image with more uniform image effect is obtained.

In the image capturing method, the target preview image may be determined as the captured image when the target preview image is determined. Wherein, the user can determine whether to select shooting according to the target preview image so as to obtain a final shooting image. For example, if the user considers that the target preview image meets the requirement, the image capturing component of the terminal can be controlled to capture an image so as to obtain a captured image. For another example, if the user considers the target preview image to be unsatisfactory, other parameters of the camera assembly may be readjusted to obtain a target preview image that meets the requirements, and then the target preview image is determined to be a captured image. That is, in the present disclosure, the target preview image may be determined as the captured image.

According to the method, after the original preview image is determined according to the first preview image collected by the first camera unit and the second preview image collected by the second camera unit, the part belonging to the first preview image and/or the second preview image in the original preview image can be adjusted according to the original preview image, so that the whole target preview image which is more coordinated and more real can be obtained, the image shooting effect is improved, and the use experience of a user is improved.

In one exemplary embodiment, an image photographing method is provided, which is applied to a terminal. In the method, determining an original preview image according to a first preview image acquired by a first camera unit and a second preview image acquired by a second camera unit may include:

s210, determining a first sub-image from the first preview image according to the first identification information;

In step S210, the specific content of the first identification information may be set according to the actual requirement, which may not be limited. The terminal may be set before the shipment of the terminal, or may be set after the shipment of the terminal, which is not limited. In addition, after the first identification information is set, the first identification information can be modified later so as to better meet the requirements of users.

The first identification information may include an identification subject, for example, including a portrait, an animal image, a still image, or other subject image, and the like, which is not limited. The first identifying information may also include identifying contours including, for example, portrait contours, triangle contours, tree contours, or contours of other shapes, without limitation. The first identification information may also include an identification color including, for example, red, green, gray, or other colors, etc., without limitation. The first identification information may include other information in addition to the above information, and is not limited thereto.

In this step, the first preview image may be identified based on the first identification information, so that an image corresponding to the first identification information is identified from the first preview image, and this image is denoted as a first sub-image.

In some embodiments of the present invention, in some embodiments,

The first identification information includes an identification subject, which may be a portrait. In this embodiment, the first preview image may be identified based on the portrait, so that an image of the portrait is identified from the first preview image, and then the identified image is determined as the first sub-image.

In some embodiments of the present invention, in some embodiments,

The first identifying information may be an identifying profile, which may be a tree profile. In this embodiment, the first preview image may be identified based on the tree profile, so that an image corresponding to the tree profile is identified from the first preview image, and the identified image is then recorded as the first sub-image.

In some embodiments of the present invention, in some embodiments,

The first identification information may be an identification color, and the identification color may be red. In this embodiment, the first preview image may be recognized based on the above red color, so that a red color image is recognized from the first preview image, and then the recognized image is determined as the first sub-image.

In step S220, after the first sub-image is determined, the original preview image may be determined based on the first sub-image and the second preview image. The first sub-image can be directly overlapped into the second preview image, so that a synthesized original preview image is obtained. Of course, the first sub-image and the second preview image may be processed in other manners to obtain the original preview image, which is not limited thereto.

According to the method, the identification information can be set according to the requirements of the user, then, when the image shooting is carried out, the first preview image can be processed based on the first identification information, and then, the final original preview image is determined according to the first sub-image obtained through processing and the second preview image, so that the image shooting is better guided, the user can shoot and obtain the image which is better in image effect and meets the requirements better, and the use experience of the user is improved.

S310, receiving a control instruction corresponding to the simulated light source information;

S320, determining target simulation light source information according to the control instruction;

S330, according to the target simulated light source information, the original preview image is adjusted.

In step S310, the simulated light source information may include brightness information of the simulated light source, position information of the simulated light source, and other information related to the simulated light source, which is not limited.

In this step, the user may input a control instruction corresponding to the simulated light source information to the terminal, so that the terminal receives the control instruction. This control instruction is used to determine target simulated light source information.

In step S320, after receiving the control instruction, the terminal may determine the target simulated light source information according to the control instruction. The terminal can respond to the control instruction to dynamically simulate the light source, namely, the terminal can simulate the corresponding original preview images under various simulated light sources so as to conveniently select the original preview images which are more coordinated and real in whole, and then determine the simulated light source information corresponding to the original preview images meeting the requirements as target simulated light source information.

In step S330, the terminal may perform light supplementing processing on the original preview image based on the target simulated light source information, so as to improve the overall effect of the original preview image, thereby obtaining a balanced and real original preview image, and then may determine the original preview image after light supplementing as the target preview image.

In some embodiments of the present invention, in some embodiments,

The terminal can be a mobile phone, and the mobile phone comprises a double-camera unit, wherein the double-camera unit comprises a front camera unit and a rear camera unit. In the mobile phone, the front camera unit can be configured with a plurality of corresponding flash lamps for supplementing light in the image shooting process of the front camera unit, and the flash lamps can be marked as front flash lamps; the rear camera unit may be configured with a plurality of corresponding flash lamps for supplementing light during image capturing of the rear camera unit, and the flash lamps may be referred to as rear flash lamps. The mobile phone is also provided with a photosensitive unit for detecting light information in a shooting environment. The light information comprises original light information in the environment and also can comprise light information sent by a mobile phone.

When shooting, the photosensitive element of the mobile phone can detect the light information of shooting environment, and after the light information is determined, the mobile phone can control the front flash lamp, the rear flash lamp and the display screen according to the light source position information and the brightness information in the light information so as to realize preliminary light supplementing.

After the preliminary light supplementing is finished, the front-end camera unit is used for performing self-shooting so as to obtain a first preview image; the rear camera unit is used for shooting three friends opposite to the user so as to obtain a second preview image.

After the front camera unit collects the first preview image and the rear camera unit collects the second preview image, the mobile phone can identify the portrait in the first preview image based on a preset identification main body (such as the portrait), so that the portrait of the user in the first preview image is selected as a first sub-image.

Then, the first sub-image and the second preview image may be subjected to a composition process, thereby obtaining an original preview image. The original preview image may include a portrait of the user and a portrait of three friends of the user, i.e., the original preview image is a composite image of the user and the three friends.

After the display screen of the mobile phone displays the original preview image, the corresponding light parameters can be adjusted based on the brightness information of each part in the original preview image so as to obtain a target preview image with better effect. For example, if the brightness of the sub-preview image is weaker than that of the second preview image in the original preview image, the front flash can be controlled to be in an on state so as to supplement light for shooting by the front camera, so that the brightness of the first preview image is improved, and the brightness of the first sub-image can be improved, so that the overall brightness of the original preview image is more balanced and real.

In this embodiment, after the mobile phone determines the original preview image, the user may input a control instruction corresponding to the simulated light source information to the mobile phone, and after receiving the control instruction, the mobile phone may respond to the control instruction to simulate the original preview image corresponding to the multiple simulated light sources, so as to select an overall more coordinated and real original preview image from the original preview image, and then determine the simulated light source information corresponding to the original preview image meeting the requirement as the target simulated light source information.

After the mobile phone determines the target simulated light source information, the original preview image can be subjected to light supplementing processing based on the target simulated light source information, so that the target preview image is obtained. And all the partial images in the target preview image are more coordinated, so that the target preview image is more real, the image shooting effect is improved, and the use experience of a user is improved.

According to the method, the original preview image is subjected to light supplementing treatment through the simulated light source, so that a target preview image with better image effect is obtained through shooting, further an image with better image effect is obtained, the shot image is more real, the image shooting effect is improved, and the use experience of a user is improved.
