Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as recited in the appended claims.

The technical solutions provided by the embodiments of the present disclosure relate to a terminal, and the terminal may be a mobile phone, a tablet computer, or other devices provided with two cameras, and the two cameras may be a front camera and a rear camera respectively. In the related art, when a user uses a terminal to take group photos for multiple friends, the user who is the photographer cannot take pictures at the same time, and the completed photos are not satisfactory because there is no user who is the photographer, and the user experience is poor. In the technical solutions provided by the embodiments of the present disclosure, when it is determined that the user uses the rear camera to capture a collective image, the terminal may instruct the front camera to turn on, and simultaneously acquire the collective image captured by the rear camera and the second image captured by the front camera , which avoids the situation that the photographer cannot take pictures for souvenirs, improves the flexibility of the terminal to take pictures and the diversity of the pictures taken, thereby improving the user experience.

Fig. 1a is a flow chart of an image processing method according to an exemplary embodiment. The image processing method is used in a terminal. As shown in Fig. 1a, the image processing method includes the following steps 101 to 103:

In step 101, it is determined whether the terminal is currently ready to use the first camera to capture a collective image.

Illustratively, the imagery may include video or photos.

The embodiments of the present disclosure are described by taking an example that the first camera is a rear camera and the second camera is a front camera. When the terminal detects that the rear camera is turned on, the interface of the terminal can display the image collected by the rear camera, and adjust the focus and focal length of the rear camera through the image, and then shoot the image.

Specifically, after the terminal is turned on through the rear camera, the number of faces included in the image displayed on the interface determines that the terminal is currently ready to use the first camera to capture collective images. If the image displayed on the terminal interface includes a large number of faces , it can be confirmed that the terminal is currently ready to use the rear camera to take group photos.

In step 102, if the terminal is currently ready to use the first camera to shoot a collective image, the second camera of the terminal is turned on.

For example, when the terminal detects that the image displayed on the interface includes a large number of faces, it may instruct the front camera to be turned on.

In step 103, the collective image captured by the first camera and the second image captured by the second camera are acquired respectively within a preset time period.

For example, when the terminal shoots a collective image through the rear camera, the terminal may simultaneously shoot the second image of the user who is the photographer through the front camera. Alternatively, after the terminal shoots the collective image through the rear camera, the terminal may use the front camera to shoot the second image of the user as the photographer 10s later, and the user as the photographer can adjust the posture and expression within the 10s. In practical applications, the preset time period may be set according to specific conditions, which is not limited in this embodiment of the present disclosure.

In the technical solutions provided by the embodiments of the present disclosure, when it is determined that the user uses the rear camera of the terminal to capture a collective image, the user may instruct the front camera to turn on, and simultaneously acquire the collective image captured by the rear camera and the second image captured by the front camera. The image avoids the situation that the photographer cannot take pictures for souvenirs, improves the flexibility of the terminal to take pictures and the diversity of the pictures taken, thereby improving the user experience.

In one embodiment, as shown in Figure 1b, the method further includes step 104:

In step 104, a combined image of the collective image and the second image is acquired according to the collective image and the second image.

For example, the terminal may acquire the combined image of the collective image and the second image in a combined manner. As shown in FIG. 1c , after acquiring the collective image 10a and the second image 10b, the terminal may splicing the collective image 10a and the second image 10b Together, the combined image 10c is composited. Specifically, the collective image 10a and the second image 10b can be spliced together according to the top-bottom structure as shown in FIG. 1c, or can be spliced together according to the left-right structure, or the second image 10b can be reduced and embedded in the collective image 10a without face information Area.

In practical applications, the terminal may also acquire the combined image of the collective image and the second image in a fusion manner. As shown in FIG. 1d, after the terminal acquires the collective image 10a and the second image 10b, the terminal may use image processing technology to merge the second image into the second image. The image of the user included in the image 10b is extracted and merged into the collective image 10a to obtain the merged image 10c.

In the technical solution provided by the embodiments of the present disclosure, after the collective image captured by the rear camera and the second image captured by the front camera are acquired, the second image and the collective image can be spliced or fused, so that the second image is The photographer and multiple subjects in the collective image can co-appear in the combined image, which avoids the situation where the photographer cannot take pictures, improves the practicability of the terminal, and further improves the user experience.

In one embodiment, as shown in FIG. 1e, in step 104, according to the collective image and the second image, obtaining a combined image of the collective image and the second image can be achieved through steps 1041 and 1042:

In step 1041, it is determined whether the second image includes preset face information.

In step 1042, if the second image includes preset face information, a combined image of the collective image and the second image is acquired according to the collective image and the second image.

For example, during initialization, preset face information can be set in the terminal, and after the terminal obtains the collective image and the second image, it can first obtain the face information included in the second image, and then determine the face information and the preset. Assuming whether the face information matches, if the face information matches the preset face information, it means that the preset face information is included in the second image, that is, the user as the photographer corresponding to the face information included in the second image is Authorize the user, at this time, the terminal can obtain the combined image of the collective image and the second image.

In the technical solutions provided by the embodiments of the present disclosure, when it is determined that the photographer in the second image is an authorized user, a combined image of the collective image and the second image is obtained, thereby avoiding the waste of storage resources caused by arbitrarily acquiring and storing the combined image. , which improves the effective utilization of storage resources.

In one embodiment, as shown in Figure 1f, the method further includes steps 105 and 106:

In step 105, a corresponding relationship between the collective image and the second image is established.

In step 106, the collective image and the second image are stored according to the corresponding relationship between the collective image and the second image.

For example, after acquiring the collective image and the second image, the terminal may generate a tag according to the shooting time, and then write the tag into the attribute information of the collective image and the second image at the same time, and then store the collective image and the second image respectively. When a user is viewing an album, the terminal can read the attribute information of the photo displayed on the current interface in real time, and then determine whether there is a photo with the same attribute information in the album. If there is, the photo with the same attribute information can be displayed on the interface at the same time. for user viewing.

In the technical solution provided by the embodiments of the present disclosure, after the collective image captured by the rear camera and the second image captured by the front camera are acquired, the collective image and the second image may be stored simultaneously according to the corresponding relationship between the collective image and the second image. The second image avoids the situation that the photographer cannot take pictures for souvenirs, improves the practicability of the terminal, and further improves the user experience.

In one embodiment, as shown in FIG. 1g, in step 101, determining whether the terminal is currently ready to use the first camera to shoot a collective image can be achieved through steps 1011 and 1012:

In step 1011, when it is detected that the first camera is turned on, it is determined whether the number of faces in the image displayed on the current interface of the terminal is greater than or equal to the number threshold.

In step 1012, if the number of human faces in the image displayed on the current interface of the terminal is greater than or equal to the number threshold, it is confirmed that the terminal is currently ready to use the first camera to shoot a collective image.

For example, the terminal can detect in real time whether the rear camera is turned on. If it is detected that the rear camera is turned on, the current interface of the terminal displays the image captured by the rear camera. At this time, the terminal can determine the person in the image displayed on the current interface. Whether the number of faces is greater than or equal to the number threshold, if the number of faces in the image displayed on the current interface is greater than or equal to the number threshold, it means that there are many people in the area captured by the rear camera at this time, so it can be determined that the terminal is currently ready to use the rear camera Take group images.

For example, the terminal can determine whether the number of faces in the image displayed on the current interface is greater than or equal to 3, and if the number of faces in the image displayed on the current interface is greater than or equal to 3, it can be determined that the terminal is currently preparing to use the rear camera to shoot a collective image . In practical applications, the quantity threshold may be adjusted according to actual conditions, which is not limited in this embodiment of the present disclosure.

The above embodiments are also applicable to the technical solutions described in FIG. 1b, FIG. 1e and FIG. 1f.

In the technical solutions provided by the embodiments of the present disclosure, whether the terminal is currently ready to use the first camera to shoot a group image is determined by the number of faces in the image displayed on the current interface of the terminal when the first camera is turned on, which improves the ability of the terminal to determine whether to shoot a group image. Convenience and accuracy of imagery, which in turn improves the user experience.

In one embodiment, as shown in FIG. 1h, in step 1012, if the number of faces in the image displayed on the current interface of the terminal is greater than or equal to a number threshold, it is confirmed that the terminal is currently ready to use the first camera Shooting a collective image can be achieved through steps 1012a to 1012c:

In step 1012a, if the number of human faces in the image displayed on the current interface of the terminal is greater than or equal to the number threshold, determine whether any two adjacent human faces among the multiple human faces included in the image displayed on the current interface of the terminal are between Whether the distance between them is less than or equal to the preset distance threshold.

In step 1012b, if the distance between any two adjacent faces among the multiple faces included in the image displayed on the current interface of the terminal is less than or equal to a preset distance threshold, determine the multiple faces included in the image displayed on the current interface of the terminal Whether the area of the display area occupied by any face in the face meets the preset area range.

In step 1012c, if the area of the display area occupied by any one of the multiple faces included in the image displayed on the current interface of the terminal satisfies the preset area range, it is confirmed that the terminal is currently ready to use the first camera to shoot a collective image.

For example, if the user takes a photo in a tourist resort with a high traffic flow, even if the user is taking a single photo for a friend, the terminal can easily misjudge the current scene as a group image ready to be taken due to the influence of other tourists. Therefore, the terminal needs to make further judgment after determining that the number of faces in the image displayed on the current interface is greater than or equal to the number threshold.

Generally, when a user shoots a group image for a plurality of friends, the distance between the friends is not too large. At the same time, in order to clearly photograph the facial features of each friend, the distance between the photographing terminal and the multiple friends who are the subjects of photographing is not too far, so the face of each friend occupies the space when displayed on the interface of the photographing terminal. The display area is neither too small nor too large. To sum up, during initialization, the terminal can set a preset distance threshold and a preset area range. After determining that the number of faces in the image displayed on the current interface is greater than or equal to the number threshold, it can continue to determine that the number of faces displayed on the current interface can be determined. Whether the distance between any two adjacent faces in the multiple faces included in the image is less than or equal to the preset distance threshold, and when the distance between any two adjacent faces is less than or equal to the preset distance threshold, Next, it is determined whether the area of the display area occupied by any one of the faces satisfies the preset area range, and if the area of the display area occupied by any one face meets the preset area range, it indicates that the terminal is currently preparing to shoot a collective image.

Exemplarily, both the preset distance threshold and the preset area range may be characterized by the pixels of the terminal display screen. For example, as shown in Figure 1i, after determining that the number of faces in the image displayed on the current interface is greater than or equal to 3, the terminal can also determine the number of any two adjacent faces among the multiple faces included in the image displayed on the current interface. Whether the distance L between them is less than or equal to 200 pixels, and if the distance L between any two adjacent faces is less than or equal to 200 pixels, determine the amount of space occupied by any one of the multiple faces included in the image displayed on the current interface of the terminal. Whether the area of the display area S is greater than or equal to 300 pixels and less than or equal to 500 pixels, if the area of the display area S occupied by any one face is greater than or equal to 300 pixels and less than or equal to 500 pixels, confirm that the terminal is currently ready to shoot group images. In practical applications, the terminal can preset the traversal direction. After determining that the number of faces in the image displayed on the current interface is greater than or equal to 3, the terminal can sequentially acquire the traversal direction of each face in the image displayed on the current interface along the preset traversal direction. The position of the face can be marked by the position of the nose in each face, and then two adjacent faces are determined according to the positions of the two adjacent noses in the traversing direction.

In practical applications, the preset distance threshold and the preset area range can also be characterized by mathematical measures of centimeters or millimeters. For example, after determining that the number of faces in the image displayed on the current interface is greater than or equal to 3, the terminal may also determine whether the distance between any two adjacent faces among the multiple faces included in the image displayed on the current interface is less than or equal to 3 It is equal to 10 mm. If the distance between any two adjacent faces is less than or equal to 10 mm, determine whether the area of the display area occupied by any one of the multiple faces included in the image displayed on the current interface of the terminal is greater than or equal to 15 mm is less than or equal to 30 mm. If the area of the display area occupied by any face is greater than or equal to 15 mm and less than or equal to 30 mm, it is confirmed that the terminal is currently preparing to shoot a group image.

The above embodiments are also applicable to the technical solutions described in FIG. 1b, FIG. 1e and FIG. 1f.

In the technical solution provided by the embodiments of the present disclosure, whether the terminal is currently ready to use the first camera is determined by the display area occupied by the face in the image displayed on the current interface of the terminal and the distance between the face and the face when the first camera is turned on. The camera shoots the collective image, which improves the convenience and accuracy of the terminal in determining whether to shoot the collective image, thereby improving the user experience.

In one embodiment, as shown in FIG. 1j, in step 101, determining whether the terminal is currently ready to use the first camera to shoot a collective image can be achieved through steps 1013 and 1014:

In step 1013, a first operation instruction is acquired, and in response to the first operation instruction, it is detected whether the first camera of the terminal is turned on.

In step 1014, when the first camera of the terminal is turned on, it is determined whether the terminal is currently ready to use the first camera to shoot a collective image.

For example, the terminal may determine, according to the user's instruction, whether it is necessary to turn on the front camera to acquire the second image when preparing to use the rear camera to shoot the group image. Specifically, a shooting application may be pre-installed on the terminal. When the user needs to shoot an image, the user may click on the icon of the application, and the terminal will open the shooting application after detecting the click. The shooting application has an option of whether to turn on the front and rear cameras at the same time, and the user can choose according to their needs. If the user chooses to enable, the user may click on the position corresponding to the option on the screen, and after detecting the click, the terminal confirms receipt of the first operation instruction. at this time. The terminal turns on the function of turning on the front and rear cameras at the same time, and detects in real time whether the rear camera of the terminal is turned on. Then, when the rear camera is turned on, it determines whether the rear camera is currently ready to be used to shoot a collective image, and then determines whether the rear camera is currently ready to shoot. For group images, turn on the front camera to obtain the second image.

The above embodiments are also applicable to the technical solutions described in FIGS. 1b , 1e , 1f , 1g and 1h .

In the technical solution provided by the embodiments of the present disclosure, the terminal may, according to the user's instruction, simultaneously acquire the collective image captured by the rear camera and the second image captured by the front camera when the terminal is currently preparing to use the first camera to capture the collective image, The waste of storage resources caused by randomly acquiring and storing the second image captured by the front camera is avoided, and the effective utilization rate of the storage resources is improved.
