Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to a shooting method and apparatus, and an electronic device.

Background

Cameras are the most common and important functions in terminals such as mobile phones, tablets or e-readers.

At present, the method for taking a picture by using the terminal comprises the following steps: one member of a team of members takes a picture of the other members, the photographer not appearing in the picture. Then, the team continues to take the picture by another member, and one member is always missing from the final picture taken. Or seeking help from strangers to shoot the group photo of all the members of the team. Further, when the photographer needs to take a picture of the subject of the scope, the photographer cannot take a picture because the subject is not in the same position as the photographer. For example, a star tracker often cannot co-ordinate with a star.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a photographing method according to an exemplary embodiment. The shooting method can be applied to electronic equipment (such as a smart phone, a tablet computer, a digital camera and the like) with a shooting function. As shown in fig. 1, the photographing method includes the following steps S101 to S103:

in step S101, when a shooting instruction is detected, controlling a first camera to shoot an image containing a subject, and taking the image of the subject as a background image;

in step S102, a superimposed area of a person image about the photographer in the background image in the finder screen of the second camera is determined;

in step S103, when the combination command is detected, the person image of the subject is combined with the superimposed area of the background image, and an image including the subject and the subject is obtained.

It should be noted that, in the embodiment of the present disclosure, the shooting instruction is generated according to a trigger operation of a photographer on a smartphone. For example, "click" operation on the display screen, or triggering a "shoot" button, or pressing the volume button "+" (or "-"). One skilled in the art can set up the method according to a specific scenario, and the present disclosure is not limited thereto.

It should be noted that the first camera and the second camera may be two cameras arranged in a back-to-back manner. For example, the first camera is a rear camera and the second camera is a front camera. The first camera and the second camera can be the same camera, at the moment, the first camera indicates that the camera points to a shot person, the second camera indicates that the camera points to the shot person, and the same camera has two different points. Of course, the first camera and the second camera can point to the same position for the same camera, and at the moment, the photographer needs to move to the position where the photographer is located before (at the moment, the smart phone is carried by others and is photographed), and the purpose of group photo can be achieved as well. Those skilled in the art can set up the method according to specific use scenarios, and the present disclosure is not limited thereto.

It should be noted that, on the basis of the first image, a second image (the area of the second image is smaller than that of the first image) is projected onto the first image, that is, the second image is superimposed on a certain region of the first image, that is, a superimposed region, and the final image displayed on the display screen after the superimposition of the second image and the first image includes the whole second image and a part of the first image (the image corresponding to the superimposed region in the first image is covered). In the embodiment of the present disclosure, the first image is referred to as a background image, and the second image corresponds to a portrait of the photographer.

In the embodiment of the present disclosure, the above-mentioned shooting method is described by taking a smart phone as an example, where the smart phone includes a front camera (top left corner in fig. 3) and a rear camera (not shown in the figure). The intelligent mobile phone is provided with a controller, and the controller is used for detecting and processing each part.

In an embodiment of the present disclosure, before using the photographing method shown in fig. 1, it is necessary to set the photographing mode of the smartphone to the group photo mode, and a setting process is shown in fig. 2(a), and includes:

first, the photographer triggers the operation "set" function box, and the controller displays a setting menu as shown in fig. 2(b) when detecting the above-mentioned trigger operation.

Then, the photographer triggers and operates a "shooting mode" function option in the above setting menu, and the controller detects the above triggering operation to display a shooting mode sub-menu, which is shown in fig. 2 (c).

Finally, the photographer triggers operation "group photo mode", and the controller displays the "confirm" and "cancel" function blocks shown in fig. 2(d) according to the above-mentioned triggering operation and continues to detect the trigger operation of the photographer. When the trigger operation of the 'confirm' function block by the photographer is detected, the shooting mode is set to 'group photo mode'.

It can be seen that, when the smartphone enters the photographing mode, as shown in fig. 3, the controller first determines whether the current photographing mode is the group photo mode, and responds to the group photo mode when determining that the current photographing mode is the group photo mode (corresponding to step S1011). The controller then detects whether a shooting instruction is detected (corresponding to step S1012), continues to wait until the shooting instruction is detected when the shooting instruction is not detected, and then the controller starts timing to a preventive period (the timing may also be completed by a timer) (corresponding to step S1013). After timing is finished, the controller switches the first camera to the second camera, and calls a preset image processing algorithm to scratch out the portrait of the photographer from the framing image of the second camera

In practical application, as shown in fig. 4, the smartphone may default that the rear camera is the first camera, and when the photographer triggers and operates the "camera" function box, a view frame of the first camera is displayed on the smartphone display screen. Referring to fig. 5, the photographer takes images of three persons, i.e., the photographer ABC, for their partner. The first camera adjusts the focal length, and generates a focus frame (a dashed frame shown in fig. 5) when it is detected that the subject B has a smiling face or meets the shooting requirement. The photographer triggers and operates the 'shooting' function box according to the prompt of the focusing frame on the display screen or the photographer according to shooting experience, and the display screen generates a shooting instruction according to the triggering operation of the photographer and sends the shooting instruction to the controller. If the photographer triggers operation of the cancel function box, the above process is repeated.

The controller is in real-time communication with the first camera, and when the shooting instruction is detected, the controller controls the first camera to shoot an image containing three persons ABC of the shot object, as shown in FIG. 6, and takes the image of the three persons ABC as a background image.

And when the controller detects that the shooting instruction indicates a timer to start timing, the timing time is preset duration. The preset duration can be set according to the action time of the first camera and the time for storing the background image into a cache or a memory. When the timing reaches the preset time length, the controller switches the rear camera into the front camera, namely, the first camera into the second camera. It can be understood that, in the embodiment of the present disclosure, the photographer may switch from the first camera to the second camera, and the photographer triggers a "camera switching" function box (for example, a camera key at the top of the display area in fig. 5) of the operation display screen.

As shown in fig. 6, a viewfinder image of the front camera is displayed on the display screen at this time. Also, the front camera adjusts the focal length, and generates a focus frame (a dashed frame shown in fig. 7) when it is detected that the subject B has a smiling face or meets the shooting requirement. The photographer triggers and operates the 'group photo' function box according to the prompt of the focusing frame on the display screen or the photographer according to the shooting experience, and the display screen generates a group photo instruction according to the triggering operation of the photographer and sends the group photo instruction to the controller. If the photographer triggers operation of the cancel function box, the above process is repeated.

The controller controls the front camera to shoot the image of the photographer according to the group photo command. Then the controller recalls a preset image processing algorithm to scratch out the portrait of the photographer (used as a reference sign D in the figure 7) from the image of the photographer, then adjusts the size of the portrait of the photographer D to be directly synthesized into a background image to obtain an image containing the photographer ABC and the photographer D as shown in figure 8, and stores a final image.

It should be noted that, in the embodiment of the present disclosure, the preset image processing algorithm refers to an image matting algorithm pre-stored in the smart phone. For example, the image Matting algorithm described above may be Real-Time Alpha Matting. Of course, those skilled in the art can select other image matting algorithms according to a specific scene, and the disclosure is not limited thereto.

In an embodiment of the present disclosure, when switching to the front camera (corresponding to step S1021) as shown in fig. 9, the person image of the photographer D is extracted in real time from the framing picture of the front camera (corresponding to step S1023), and then the framing picture of the front camera is closed and the person image of the photographer D is superimposed on the background image (corresponding to step S1024). As shown in fig. 10, the lower layer image in fig. 10 is a background image, the upper layer image is a person image of a photographer, and a black portion in the background image is a projection of the person image of the photographer in the background image. The black part is an overlapping area of the portrait of the photographer in the background image. The background image and the portrait of the photographer are superimposed and the image is displayed on the display screen (as shown in fig. 11).

The embodiment of the disclosure can directly close the front camera by closing the framing picture of the front camera, and at the moment, the front camera does not collect images, and the controller only reads background images from a cache or a memory. Of course, the display priority of the finder screen of the front camera and the display priority of the background image may be adjusted. The display reads the background image from the cache or the memory according to the display priority for displaying, the front-facing camera continues to collect the image and stores the image in the cache or the memory, and the display screen cannot read and display the image due to the lower display priority. Those skilled in the art can set the usage according to the specific scenario, and the embodiment of the disclosure is not limited.

And then, the display screen generates a group photo instruction according to the trigger operation of the photographer and sends the group photo instruction to the controller. When the synthesis instruction is detected, the controller synthesizes the portrait of the photographer in the superposition area of the background image to obtain the image containing the photographed person and the photographer.

To acquire a plurality of group images, after step S102, as shown in fig. 12, the controller according to an embodiment of the disclosure further acquires parameter values of the background image within a preset range outside the overlap region as suggested parameter values (corresponding to step S1025). The width of the preset range may be set according to a specific scene. Thereafter, the controller adjusts the parameter value corresponding to the person image of the photographer based on the recommended parameter value acquired in step S1025, and generates at least one recommended image including the subject and the photographer (corresponding to step S1026).

As shown in fig. 13, the preset range is a shaded portion of the edge of the overlap region. And after the controller acquires the suggested parameter value, the controller adjusts the parameter value corresponding to the portrait of the photographer, so that the portrait and the background image can be more coordinated. It is understood that the controller can place the portrait at different positions of the background image respectively, and obtain at least one suggested image containing the photographed person and the photographer according to the above adjustment process. And temporarily storing the at least one suggested image in a cache, and displaying the suggested image on the display screen in a rolling manner at a preset frequency until the display screen generates a group photo instruction according to the triggering operation of a photographer and sends the group photo instruction to the controller. The controller synthesizes the portrait in the superposition area of the background image according to the group photo command to obtain an image containing the shot object and the shot object. And deleting the rest unselected suggested images.

In an embodiment of the present disclosure, the updating of the superimposed area on the background image of the portrait of the photographer may be set by the photographer, as shown in fig. 14, including:

a photographer performs trigger operation on a display screen to determine a designated position; the specified position corresponds to a position in the background image. The display then generates a replacement area command based on the designated location and sends it to the controller (corresponding to step S1027). When the replacement area command is detected, the controller newly determines the superimposition area of the portrait of the photographer in the background image based on the designated position (corresponding to step S1028).

In an embodiment of the present disclosure, a photographer may adjust a background area according to a specific scene. As shown in fig. 15, when a photographer performs a trigger operation on the display screen, the trigger operation corresponds to the background image corresponding area, and the display screen generates a corresponding trigger operation instruction according to the trigger operation and sends the trigger operation instruction to the controller. The controller acquires a current value of a first preset parameter corresponding to the background image and displays the current value (corresponding to step S1029). And the photographer selects the current values of one or more first preset parameters according to the displayed current values and adjusts the current values to target values, and the display screen sends the target values to the controller. The controller updates the current value of the corresponding preset parameter to the corresponding target value (corresponding to step S1030).

As shown in fig. 16, when the display screen detects that the photographer triggers the operation of the background image corresponding area, the display screen sends the above-mentioned triggering operation to the controller. The controller obtains a current value of a first preset parameter corresponding to the background image, and the current value is displayed by the display screen. The first preset parameter may include one or more of a position, a size, a brightness, a color level, a hue, a contrast, and a saturation, which may be selected by a person skilled in the art according to a specific scenario, and the disclosure is not limited thereto. For example, as shown in fig. 17, the photographer may adjust the position of the background image so that the background image moves to the left, right, up, or down, which is more harmonious with the photographer's portrait. The center position of the background image is (X, 0; Y, 0), and when moving to the left, the center position thereof may be modified to be (X, -2; Y, 0), at which time the background image moves 2 units to the left. As another example, when the center position is modified to (X, -2; Y, +2), the background image is moved leftward by 2 units and then upward by 2 units. The setting can be performed by those skilled in the art according to specific scenarios. Other first preset parameters may also be adjusted in an increasing or decreasing manner.

And after the photographer modifies the current value of the first preset parameter into the target value, the controller updates the background image according to the target value of the first preset parameter and displays the background image on the display screen again. Of course, the person skilled in the art may adjust the first preset parameter as many times as necessary until the photographer is satisfied.

In an embodiment of the present disclosure, a photographer can adjust an area corresponding to a portrait of the photographer according to a specific scene. As shown in fig. 18, when a photographer performs a trigger operation on the display screen, the trigger operation corresponds to a region corresponding to a portrait of the photographer, and the display screen generates a corresponding trigger operation instruction according to the trigger operation and sends the trigger operation instruction to the controller. The controller acquires and displays a current value of the second preset parameter corresponding to the portrait of the photographer (corresponding to step S1031). And the photographer selects the current values of one or more second preset parameters according to the displayed current values and correspondingly adjusts the current values to the target values, and the display screen sends the target values to the controller. The controller updates the current value of the corresponding preset parameter to the corresponding target value (corresponding to step S1032).

As shown in fig. 19, when the display screen detects that the photographer triggers the operation portrait corresponding area, the display screen sends the above-mentioned triggering operation to the controller. And the controller acquires the current value of the second preset parameter corresponding to the portrait and displays the current value by the display screen. The second preset parameter may include one or more of a position, a size, a brightness, a color level, a hue, a contrast, and a saturation, which may be selected by a person skilled in the art according to a specific scenario, and the disclosure is not limited thereto. For example, as shown in fig. 20, the photographer may adjust the position of the portrait of the photographer to move the portrait to the left, right, up, or down, which is more consistent with the portrait of the background image. The portrait central position is (X, 0; Y, 0), and when moving to the left, the central position can be modified to be (X, -2; Y, 0), and the portrait moves to the left by 2 units. As another example, when the center position is modified to (X, -2; Y, +2), the portrait is moved left by 2 units and then up by 2 units. The setting can be performed by those skilled in the art according to specific scenarios. Other second preset parameters may also be adjusted in an increasing or decreasing manner.

And after the photographer modifies the current value of the second preset parameter into the target value, the controller updates the portrait according to the target value of the second preset parameter and displays the portrait on the display screen again. Of course, the person skilled in the art may adjust the second preset parameter as many times as necessary until the photographer is satisfied.

In practical application, different triggering operation modes can be adopted for modifying the second preset parameter of the portrait or adjusting the designated position of the portrait. For example, when the photographer directly adjusts the position of the portrait, the photographer may first trigger to operate the area corresponding to the portrait, and move the portrait to the designated position in a dragging manner after the portrait is selected. For another example, the photographer first triggers the region corresponding to the portrait for a long time, and then triggers a certain position (i.e., a designated position) of the background image after the portrait is selected, and the controller moves the portrait to the designated position. The embodiment of the present disclosure only illustrates a manner of adjusting the overlapping position of the portrait with respect to the background image, and regarding modifying the background image, the preset parameters of the portrait, and the like, the trigger operation manner may also be adjusted by the photographer according to the usage habit of the photographer, and details are not repeated herein.

Therefore, the method provided by the embodiment of the disclosure can use the image of the photographed person acquired by the first camera as the background image; then acquiring a portrait of a photographer from a framing picture of the second camera, and superposing the portrait of the photographer to the background image; and finally, synthesizing the portrait of the photographer in the superposition area of the background image according to the synthesis instruction, and obtaining an image containing the photographer and the person to be shot as a final image. Therefore, the shooting position of the photographer is not required to be adjusted by the photographer, the photo can be combined with the photographer, the photographing convenience is improved, and the user experience is further improved.
