Detailed Description

In the process of shooting by using electronic equipment, moon is a common shooting subject, and with the progress of technology, users have higher and higher requirements on the shooting effect of moon. In the related art, in order to obtain a better moon shooting effect, a professional shooting mode is often required, and for an ordinary user, it is difficult to adjust shooting parameters, so that the clear moon image is not obtained.

In order to solve the above technical problems, the present disclosure provides a method for capturing moon, which is applied to an electronic device, and includes: when a shooting picture comprises a first image, adjusting the focal length of a camera according to a preset zooming rule, displaying the first image in a preset map area of the shooting picture, and generating a preview image; wherein the first image is a moon image; and generating a target image according to the preview image. By using the method disclosed by the application, the moon in the shooting picture can be automatically identified, the display of the moon image in the preset composition area can be automatically regulated, and the shooting effect of the moon can be improved.

In an exemplary embodiment, the method of the present embodiment is applied to an electronic device, and the electronic device may be, for example, a portable electronic device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device.

The electronic device generally includes a processor, a memory, and a display screen, to enable operation of the electronic device system or operation of application programs. Wherein the processor performs various functions of the electronic device and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory, and invoking data stored in the memory. For example, the processor may include one or more of a Central Processing Unit (CPU), an image processor (GPU), a modem, and the like. The CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing the content required to be displayed by the display screen; the modem is used to handle wireless communications. The memory may be used to store instructions, programs, code sets, or instruction sets. For example, the storage program area of the memory may store instructions for implementing an operating system, instructions for performing at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing a control method, and the like.

The electronic device may implement a photographing function through an image processor (GPU), an Image Signal Processor (ISP), a camera assembly, a display screen, a Central Processing Unit (CPU), and the like. The ISP is used for processing data fed back by the camera assembly (the ISP can also be arranged in the camera assembly), a photosensitive element (CCD or CMOS) of the camera assembly converts an optical signal into an electric signal, the electric signal is transmitted to the ISP to be converted into a digital image signal, the ISP outputs the digital image signal to a Digital Signal Processor (DSP) for processing, and the DSP converts the digital image signal into an image signal in a standard RGB format and the like, so that the display of a shooting image on the electronic equipment is finally realized.

Taking an intelligent device with an operating system as an android system as an example, a Linux kernel layer, a system operation library layer, an application framework layer and an application layer are stored in a memory. The Linux kernel layer provides a bottom layer of drive, such as a display drive, an audio drive and the like, for various hardware of the intelligent device. The system runtime layer provides main characteristic support for the Android system through some C/C++ libraries, such as the OpenGL/ES library provides support for 3D drawing. The application framework layer provides various APIs that may be used in building applications, such as building the following: window management, view management, etc. The application layer has at least one application running therein, which may be native to the operating system, such as a camera program.

As shown in fig. 1, the method of the present embodiment includes the following steps:

s110, when a shooting picture comprises a first image, adjusting the focal length of a camera according to a preset zooming rule, displaying the first image in a preset map area of a shooting interface, and generating a preview image; wherein the first image is a moon image;

s120, generating a target image according to the preview image.

When the operation that the user clicks the camera icon on the main interface of the display screen is received, the electronic device starts the camera application, and based on the shooting picture in the viewfinder of the camera, a shooting interface can be formed on the camera program, and the shooting interface of the camera is shown in fig. 6 to 10.

In step S110, whether the shot image includes the first image (i.e. the image of the moon) is identified by using a preset algorithm, for example, an AI algorithm is invoked to identify whether the preset object in the shot image is the moon: and acquiring the characteristics of the preset object in the shooting picture, judging whether the characteristics of the preset object are consistent with the characteristics of the pre-stored moon, and if so, determining that the preset object is the moon. After determining that the shooting picture contains the first image, the moon form (full moon or half moon, etc.) can be identified, namely, the image features of the moon are compared with the pre-stored moon form features. The function or algorithm for moon identification and the algorithm for processing the image may be provided at the application framework layer.

The preset zooming rule comprises focal length adjustment and focusing in the process of shooting the moon so as to shoot and obtain a moon image with proper size and definition. For example, the preset zoom rule may be: when the moon is identified to be contained in the shooting picture, an automatic shooting mode is selected based on the operation information of a user, the electronic equipment automatically invokes a long focus lens in the camera component, and adjusts zoom multiple (such as 30 times and above) in a mixed zooming mode (zooming is realized by using a mode of a lens focal length combining algorithm), and before or after the focal length is adjusted, the moon can be automatically focused. Alternatively, the preset zoom rule may be: when the moon is identified to be contained in the shooting picture, a user manually drags a focal length adjusting area of the shooting interface to control the zoom of the tele lens until the size of the moon image is matched with the size of the preset composition area, and the moon image can be clicked to be manually focused in the shooting process. And shooting a moon image by adopting a preset zooming rule, and displaying the obtained moon image in a preset map area in an adaptive manner.

The preset composition area is an area where the moon image (namely the first image) is displayed; when the first image is adaptively displayed in the preset composition area 1, a preview image is generated.

In one example, as shown in fig. 6 and fig. 7, after the user selects the automatic shooting mode (illustrating the clicking position) according to fig. 6, the electronic device automatically focuses according to fig. 7 and automatically triggers the shutter of the camera to continuously acquire a plurality of first images 2 including the preset composition area 1 and generate a plurality of corresponding preview images, so as to realize rapid capturing of moon images and avoid blurring of images caused by shaking.

In another example, as shown in fig. 8 and 9, the user may manually adjust the focal length as shown in fig. 8 and manually click the shutter of the photographing interface as shown in fig. 9 to photograph the moon 2 image. The display of the preview image on the shooting interface may be controlled and displayed by the instruction of the view management receiving processor.

In step S120, the electronic device invokes an AI image algorithm to perform screening comparison on the plurality of preview images, and selects and stores a frame image with the best display effect in the preview images as a target image. The frame image with the best display effect may be, for example, an image with the best definition of the moon, the best contrast between the moon image and the night sky background, and the best color of the moon surface in the preview image.

It is understood that the preview image or the target image is an image including a background image and a moon image within a preset composition area. Under the actual application scene, when the purpose of the user is to shoot the moon, before step S110, the electronic device may be first erected or fixed at the preset position, so as to prevent the shot picture from shaking due to the action of the user, and meanwhile, the moon should be ensured to appear in the preset map area during the fixing process of the electronic device.

In an exemplary embodiment, as shown in fig. 2, step S110 specifically includes the following steps:

s1101, adjusting the size of the first image to be matched with the preset composition area according to a preset zooming rule.

S1102, according to the position of a preset composition area, the geometric center of the first image is adjusted to coincide with the geometric center of the composition area.

In step S1101, the preset composition area is a composition reference area displayed in the shooting interface, and the preset composition area is used for indicating a reference position and a reference size of the moon in the shooting process. As shown in fig. 7, the adaptation of the first image 2 to the preset composition area 1 means that: when the moon is photographed, the reference position of the first image 2 is the position of the preset composition area, and the reference size of the first image 2 is adapted to the size of the preset composition area. For example, when the moon is full, the image of the moon coincides with the preset composition area and has the same area. For example, when the moon is in the form of a half-moon or a meniscus, the first image 2 is located at the center of the patterned area 1.

In step S1102, the size of the first image 2 obtained through zooming is adapted to the preset composition area 1, but there may be a deviation in the position of the first image 2. In this step, the image including the moon is cut or moved based on an algorithm so that the display position of the moon image is adapted to the position of the preset composition area. For example, when the moon is full, cutting the image containing the moon to enable the image of the moon to coincide with the preset composition area; when the moon is in the form of a half moon or a meniscus, the image containing the moon is cut so that the geometric center of the image of the moon coincides with the geometric center of the preset composition area, that is, the first image is located at the center of the composition area.

In this embodiment, when the first image is included in the photographed image, the display effect of the first image may also be optimized. The manner of optimizing the display effect of the image of the moon may include: the image (such as brightness, size and outline of the moon) of the moon is dynamically adjusted according to shooting scenes (such as ambient light conditions, shooting positions and the like) through an AI algorithm, so that details and resolution of the moon are enhanced. For example, during shooting, the exposure compensation (EV), the effect of intelligently strengthening or sharpening moon surfaces, the effect of intelligent color and white balance are intelligently increased or decreased. Wherein when the ambient light source is darker, the exposure compensation can be increased to highlight the image sharpness. The step aims to enhance the moon image and reduce the shooting background interference (such as the depression of the brightness of night sky) in the shooting process so as to shoot the clear and crystal beautiful moon image.

In an exemplary embodiment, as shown in fig. 3, the method of the present embodiment includes the steps of:

s210, when a shooting picture comprises a first image, adjusting the focal length of a camera according to a preset zooming rule, displaying the first image in a preset map area of a shooting interface, and generating a preview image; wherein the first image is a moon image;

s220, generating a target image according to the preview image.

S230, receiving input information of a user.

S240, responding to the input information, and displaying a superimposed image in a preset mode on a shooting interface; the preset mode comprises a dynamic mode or a static mode, and the superimposed image comprises at least one of a silhouette image, a watermark image and a weather effect image.

In this embodiment, the specific implementation of steps S210 to S220 may refer to steps S110 to S120, and will not be described in detail in this embodiment.

In step S230, the input information of the user may be an operation indicating the selection of the user, such as clicking or dragging the preset floating window area.

In step S240, based on the selection of the user, the superimposed image may be displayed on the photographing interface so that the target image has different artistic effects. For example, the superimposed image is a silhouette or a watermark, and the silhouette or the watermark is added to the moon image, so that the shooting effect and the shooting experience are effectively improved. In addition, in addition to the silhouette image, the watermark image (such as a text watermark), and the weather effect image, an audio effect may be superimposed on the target image to generate an audio file.

The static silhouette may be, for example, a JPG format of an aircraft, a branch, a window, or the like. The weather effect can be weather background such as rainy days, cloudy days, snowy days and the like, and supports static and dynamic effects and dynamic simulation of rainy and snowy weather. The audio effect may be, for example: the user selects the audio file preset by the system or stored by the electronic equipment to be overlapped to the reference display image; the use scene added with the audio effect is preferably used in the reference display image added with the dynamic artistic effect, and the length of the audio is matched with the duration of the dynamic effect file. It can be appreciated that the shape and size of the superimposed image such as silhouette, watermark, etc. can be adapted to the shape and size of the shooting interface, or to the shape and size of the image preview area in the shooting interface; and an area which is adapted to the preset composition area is set in the superimposed image.

The target image with the static mode overlay image may be in JPG format, compatible with static silhouettes or static watermarks. The target image with the dynamic mode overlay image may be a dynamic file in GIF format or MP4 format, compatible with dynamic silhouette, dynamic watermark, or dynamic weather effect. The target image of the superimposed audio effect may be a dynamic file in MP4 format, adapted to the audio effect.

For example, in some embodiments, before the first image is displayed in the preset map area of the photographing interface, or while the first image is displayed in the preset map area of the photographing interface, an initial overlay image of a preset mode may be displayed on the photographing interface by default, and the initial overlay image may be at least one of a silhouette image, a watermark image, and a weather effect image.

In an exemplary embodiment, as shown in fig. 4, the method of the present embodiment includes the steps of:

s310, when a shooting picture comprises a first image, adjusting the focal length of a camera according to a preset zooming rule, displaying the first image in a preset map area of a shooting interface, and generating a preview image; wherein the first image is a moon image;

s320, generating a target image according to the preview image.

S330, receiving input information of a user; the input information includes first input information and second input information.

S340, responding to the first input information of the user, and generating a preview floating window of at least one silhouette image on the shooting interface.

And S350, responding to second input information of the user in the preview floating window, and displaying the target silhouette image in the at least one silhouette image to the shooting interface in a dynamic mode.

In this embodiment, the specific implementation of steps S310 to S320 may refer to steps S210 to S230, which are not described in detail in this embodiment.

In step S340, the first input information may be, for example, an operation of clicking an icon of the superimposed image in the photographing interface by the user, or an operation of sliding the region of the superimposed image in the photographing interface by the user. Based on the first input information of the user, a preview floating window of each silhouette image is generated on the photographing interface. The preview floating window of each silhouette image may be: the plurality of silhouette images are displayed in a list form along a length direction or a width direction of the electronic device, including a dynamic mode or a static mode of silhouette images.

In this step, as shown in fig. 10, the preview floating window may be displayed above the photographing interface and along the width direction of the electronic device. For example, the user clicks the corresponding icon, and the preview floating window area of the various silhouettes may be displayed above the photographing interface in a popup window. For another example, the user may slide the superimposed image area, and the preview floating window area of each silhouette image may be displayed above the photographing interface in an animated form.

In step S350, the second input information may be any specific silhouette image in the preview floating window clicked by the user. For example, when the user clicks a floating window area corresponding to a static silhouette image in the preview floating window, the user determines to select the static silhouette, and presents the static silhouette to the shooting interface in a dynamic form.

In one example, in the process that the static target silhouette image is presented to the shooting interface in a dynamic form by an initial position (such as its position in the preview floating window), the dynamic form may be: and the display size of the static target silhouette image is gradually enlarged from the initial position, laid and displayed on a shooting interface.

In another example, in the process that the static target silhouette image is presented to the shooting interface in a dynamic form from the initial position, the dynamic form may also be: and gradually reducing the display transparency of the target silhouette image from the initial position to the shooting interface from the first transparency to the second transparency, for example, displaying the static target silhouette image on the preview floating window at the initial position with the first transparency, and gradually reducing the transparency of the floating window area of the static target silhouette image according to a preset proportion in the process of selection and movement until the target position in the preset structure area is displayed with the second transparency, so that the normal display effect of the silhouette image is restored. Illustratively, the first transparency may be 80% transparency and the second transparency may be 0% transparency.

In another example, after the static target silhouette image is selected, the manner in which the static target silhouette image is presented to the shooting interface may be: the user presses down the floating window area of the static target silhouette image, drags the floating window area to the user-defined position, and then the static target silhouette image is paved on the shooting interface.

In combination with the above two examples, the static silhouette image or the static watermark may have a preset display gray level, and be laid on the shooting interface in the manner of the above example, and be displayed on the shooting interface in a superimposed manner by the preset display gray level, for example, as shown in fig. 10, the first image in the preview image has a black silhouette effect.

In another example, a dynamic target silhouette image may also be selected, including moving objects (such as animals or people in the silhouette). On the shooting interface, the moving object can be moved from the first preset position to the second preset position along the preset track in the target silhouette image, so that the shooting artistic effect is further improved.

It will be appreciated that the dynamic display modes in the above examples may be used alone or in combination. For example, in the process of displaying the target silhouette image on the shooting interface, the display size of the target silhouette image may be gradually increased from the initial position to be displayed in a laying manner, and in this process, along with the change of the target silhouette image to the preset size, the moving object in the target silhouette image moves from the first preset position to the second preset position along the preset track. The target silhouette image may be changed to a preset size, and the size of the initial position of the target silhouette image may be increased by a preset proportion, changed to a preset size, or laid at a first preset position.

In an exemplary embodiment, as shown in fig. 5, after step S350, step S360 may further include:

s360, in response to the third input information of the user, displaying the target silhouette image in a dynamic form or a static form on the shooting interface is canceled.

In this step, the third input information may be, for example, the target silhouette image selected in step S350 is double-clicked by the user, or the user performs a sliding operation on the target silhouette image toward the edge of the shooting interface, so as to cancel and display the target silhouette image.

By way of example, the process of displaying the target silhouette image on the shooting interface is canceled, and the target silhouette image may disappear in one or several dynamic forms as follows: for example, the display size of the target silhouette image gradually decreases from the position where the target silhouette image is laid and displayed on the photographing interface to the initial position. For another example, the second transparency of the laying position of the shooting interface is gradually increased to the first transparency, and the target silhouette image returns to the initial position. For another example, the moving object in the target silhouette image moves from the second preset position along the preset track to return to the first preset position.

If it is desired to reselect the silhouette image, steps S340 to S350 may be performed again or step S350 may be performed again.

In combination with the above embodiment, the present disclosure may display the superimposed image of the preset mode on the photographing interface, which may be that the superimposed image is displayed on the photographing interface during the photographing process. After the preview image is generated, the superimposed image may be displayed on the preview image.
