The video call 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.

Fig. 1 is a flowchart illustrating a video call method provided in an embodiment of the present application, where the video call method is applied to a first electronic device, and the video call method may include:

step 101: the method comprises the steps that under the condition that video call connection is established between first electronic equipment and second electronic equipment, a first image collected by a first target camera module is obtained.

The first target camera module comprises at least two wide-angle lenses, and the first image is obtained by synthesizing images collected by the at least two wide-angle lenses in the first target camera module.

In the embodiment of the application, under the condition that the first electronic device is connected with the second electronic device in a video call mode, the video images of the local end can be collected through a plurality of wide-angle lenses in the first target camera module, and the video images collected through the plurality of wide-angle lenses are subjected to image synthesis processing to obtain the first image. The first image obtained in this way has a wider image visual angle range and richer content.

Step 102: and sending the first image to the second electronic equipment.

After obtaining the first image, the first electronic device may send the first image to the second electronic device as a local video image. After receiving the first image, the second electronic device may display the first image for viewing by the user.

Because the first image is obtained by synthesizing the images collected by the wide-angle lenses, the range of the image visual angle is larger, and the image information displayed during the video call is increased, the user at the second electronic equipment can see the video image with richer content, the blending feeling of the user is improved, and meanwhile, the target object which the user wants to see through the mobile video call equipment or the mobile counterpart can be reduced to a certain extent during the video call, so that the counterpart can watch the operation frequency.

As an optional embodiment, in this embodiment of the application, the first target camera module may be a front camera module or a rear camera module of the first electronic device, that is: when the video calls, the video images with larger visual angle range can be acquired through the front camera module, and the video images with larger visual angle range can also be acquired through the rear camera module, so that different requirements of users are met. Especially for the front camera module, in the process of realizing the application, the inventor finds that: the user often uses the front camera module to carry out video call to show the image of oneself for the other side, but because the distance of user's distance from front camera module is close, lead to the user's image to occupy most image area, make the other side to be difficult to see the thing around the user. And after the shooting visual angle of the front camera module is increased, the embodiment of the application can enable the opposite side to better watch the objects around the user. It can be understood that, the first target camera module may be a front camera module or a rear camera module of the first electronic device, or may be a camera module disposed at 0 other position of the first electronic device, for example, the first target camera module is a camera module disposed at a frame position of the first electronic device.

As an optional embodiment, in the embodiment of the present application, the wide-angle lenses included in the first target camera module may all be disposed in the same camera module, so that the occupation of the internal space of the electronic device may be reduced, and at this time, the first target camera module may include at least one camera module. It can be understood that the wide-angle lens included by the first target camera module can also be respectively arranged in different camera modules, for example, each wide-angle lens corresponds to one camera module, and at the moment, the first target camera module includes at least two camera modules. For the two structures, the specific situation can be set according to actual requirements.

As an alternative embodiment, the first target camera module may include a wide-angle lens with the same lens parameters. The wide-angle lens with the same lens parameters has the same parameters of the collected images, such as the number of pixels in each row and each column, so that the image synthesis processing can be conveniently carried out, and the data processing of the image synthesis is simpler.

As an alternative embodiment, the wide-angle lens of the first target camera module, which is engaged in the video call, may be deflected by a preset angle setting toward a preset direction to obtain a composite image with a larger viewing angle.

For example, the first target camera module may include: the first wide-angle lens and the second wide-angle lens are two wide-angle lenses. The first wide-angle lens and the second wide-angle lens are wide-angle lenses with the same lens parameters, and the first wide-angle lens and the second wide-angle lens are respectively deflected to the direction departing from the opposite side to be symmetrically arranged at preset angles, so that images collected by the first wide-angle lens and the second wide-angle lens are subjected to synthesis processing.

The first wide-angle lens 201 is deflected to the left by 30 ° with respect to the second wide-angle lens 202, and the second wide-angle lens 202 is deflected to the right by 30 ° with respect to the first wide-angle lens 201.

Wherein, include at first target camera module: under the condition of two wide-angle lenses of first wide-angle lens and second wide-angle lens, the value range of the angle of predetermineeing of each wide-angle lens deflection can be: greater than 0 ° and less than half of the angle of view of the wide-angle lens. For example, the view angle of the first wide-angle lens is 120 °, then the range of the preset angle for the deflection of the first wide-angle lens is: the angle is larger than 0 degrees and smaller than 60 degrees, so that the images collected by the two wide-angle lenses have overlapped image contents, and the images with larger visual angles can be obtained after image synthesis.

Wherein, include at first target camera module: under the condition of two wide-angle lenses of the first wide-angle lens and the second wide-angle lens, the first wide-angle lens and the second wide-angle lens can be arranged in a bilateral symmetry mode or in an up-down symmetry mode. When the video camera is arranged symmetrically left and right, the visual angle of the video image can be increased horizontally; when the two video images are arranged symmetrically up and down, the visual angle of the video images can be increased longitudinally. Here, the longitudinal direction herein refers to a top-to-bottom (or bottom-to-top) direction of the first electronic device, and the lateral direction herein refers to a direction perpendicular to the top-to-bottom (or bottom-to-top) direction of the first electronic device.

It should be noted that the above left and right and up and down are relative to the user, that is, the left is: the side, provided with the first target camera module, of the first electronic device is opposite to the front of the user, and the top of the first electronic device and the head of the user face the left direction of the user when the top of the first electronic device and the head of the user are in the same direction; the right here means: the side, provided with the first target camera module, of the first electronic device is opposite to the front of the user, and the top of the first electronic device faces the direction of the right side of the user when the top of the first electronic device and the head of the user are in the same direction. The above means here: the side, provided with the first target camera module, of the first electronic device is opposite to the front of the user, and the top of the first electronic device faces the head of the user when the top of the first electronic device and the head of the user are in the same direction; the following is referred to herein: the first electronic equipment is provided with a first target camera module, one side of the first electronic equipment is opposite to the front of a user, and the top of the first electronic equipment faces the direction of the feet of the user when the top of the first electronic equipment and the head of the user are in the same direction.

Wherein, to the wide-angle lens that includes in the first target camera module, can set up its deflection angle fixed unchangeable, also can set up its deflection angle adjustable, and particular case can set up according to actual demand.

As an optional embodiment, the video call method may further include:

and the first electronic equipment acquires a second image acquired by the second target camera module under the condition that the first electronic equipment establishes video call connection with the second electronic equipment, and sends the second image to the second electronic equipment.

In this embodiment of the application, when a first electronic device establishes a video call connection with a second electronic device, a video image is collected through a first target camera module, and a video image is also collected through a second target camera module, and the first target camera module and the second target camera module are respectively one of a front-facing camera module and a rear-facing camera module, that is, in this embodiment of the application, video images (i.e., a first image and a second image) collected by the front-facing camera module and the rear-facing camera module can be simultaneously sent to the second electronic device during the video call. After the second electronic equipment receives the first image and the second image, the first image and the second image can be displayed simultaneously, so that a user at the second electronic equipment end can view the video image collected by the front camera module of the first electronic equipment and view the video image collected by the rear camera module of the second electronic equipment, and the content of the video image which can be seen by the user at the second electronic equipment end is further enriched.

As shown in fig. 3, in the video call interface of the second electronic device, a first image 301 and a second image 302 transmitted by the first electronic device are respectively displayed. It is understood that the display positions of the first image 301 and the second image 302 may be interchanged, i.e.: the first image 301 is displayed in a reduced size in the upper right corner of the screen and the second image 302 is displayed in a magnified full screen size. Of course, the user may select to display only the first image 301 or only the second image 302 according to his/her needs. In addition, when the first image 301 and/or the second image 302 are displayed, a video image acquired by the second electronic device may also be displayed, and the specific situation may be set according to actual requirements.

As an alternative embodiment, the second target camera module may further include: at least two wide-angle lenses, and the second image is synthesized by the images collected by the at least two wide-angle lenses.

In the embodiment of the application, when the video image at a larger visual angle is obtained through the first target camera module, the video image at the larger visual angle can be obtained through the second target camera module, so that the video image at the larger visual angle can be obtained by the front camera module and the rear camera module, and the content of the video image is further enriched.

In order to facilitate image synthesis processing, at least two wide-angle lenses in the second target camera module may be wide-angle lenses having the same lens parameters.

The wide-angle lens participating in the video call in the second target camera module can deflect towards a preset direction by a preset angle to obtain a synthetic image with a larger visual angle. For example, the second target camera module may include: the third wide-angle lens and the fourth wide-angle lens are two wide-angle lenses. The third wide-angle lens and the fourth wide-angle lens are wide-angle lenses with the same lens parameters, and the third wide-angle lens and the fourth wide-angle lens are respectively deflected to the direction departing from the opposite side to be symmetrically arranged at preset angles, so that images collected by the third wide-angle lens and the fourth wide-angle lens are subjected to synthesis processing.

When the video camera is arranged symmetrically left and right, the visual angle of the video image can be increased horizontally; when the two video images are arranged symmetrically up and down, the visual angle of the video images can be increased longitudinally. The longitudinal direction herein refers to a top-to-bottom (or bottom-to-top) direction of the first electronic device, and the lateral direction herein refers to a direction perpendicular to the top-to-bottom (or bottom-to-top) direction of the first electronic device.

It should be noted that the above left and right and up and down are relative to the user, that is, the left is: the side, provided with the second target camera module, of the first electronic equipment is opposite to the front of the user, and the top of the first electronic equipment faces the left direction of the user when the top of the first electronic equipment and the head of the user are in the same direction; the right here means: the side, provided with the second target camera module, of the first electronic device is opposite to the front of the user, and the top of the first electronic device faces the direction of the right side of the user when being in the same direction with the head of the user. The above means here: the side, provided with the second target camera module, of the first electronic equipment is opposite to the front of the user, and the top of the first electronic equipment faces the head of the user when being in the same direction with the head of the user; the following is referred to herein: the side, provided with the second target camera module, of the first electronic device is opposite to the front of the user, and the top of the first electronic device and the head of the user face the direction of the feet of the user when the top of the first electronic device and the head of the user are in the same direction.

Wherein, to the wide-angle lens that includes in the second target camera module, can set up its deflection angle fixed unchangeable, also can set up its deflection angle adjustable, and particular case can set up according to actual demand.

The structure of the second target camera module is similar to that of the first target camera module, and for the structure of the second target camera module, the description of the first target camera module in the foregoing can be specifically referred to, and the description is omitted here.

As an optional embodiment, in the embodiment of the present application, multiple video call modes may be set for the user to select. For example, during a video call, the first electronic device displays a video call mode option in response to a first input from a user after receiving the first input. And after receiving a second input of the user, the first electronic equipment responds to the second input and controls the video call mode corresponding to the target video call mode option selected by the second input to carry out video call.

As shown in fig. 4, the first input may be a touch operation performed on a "switch camera" control 303 in the video call interface. The video call mode options described herein may include: a front mode option 304, a pan mode option 305, and a pan mode option 306. The target video call mode option is one of the displayed video call mode options.

The front shooting mode is to start the front camera module to carry out video call. When the video call is carried out in the pre-shooting mode, the image collected by the front camera module of the first electronic equipment and the video image collected by the camera module used for carrying out the video call can be displayed in the screen of the second electronic equipment.

The rear camera mode refers to that only the rear camera is started to carry out video call. When the video call is carried out in the post-shooting mode, the image collected by the rear-mounted camera module of the first electronic equipment and the video image collected by the camera module used for carrying out the video call can be displayed in the screen of the second electronic equipment.

The front-back shooting mode refers to that the front camera and the rear camera are simultaneously started to carry out video call. When carrying out video call with the mode of shooing around, can show the image that leading camera module and the rearmounted camera module of first electronic equipment gathered in the screen of second electronic equipment to and self be used for carrying on the video image that the camera module of video call gathered.

As an alternative embodiment, the following further explanation of the image composition process described in the embodiment of the present application is continued by taking an example in which the first target camera module includes two wide-angle lenses, i.e., a first wide-angle lens and a second wide-angle lens.

The step 101 of "acquiring the first image acquired by the first target camera module" may include:

acquiring a first sub-image and a second sub-image; carrying out graying processing and binarization processing on the first sub image and the second sub image; determining an image area with the same image content between the first sub-image and the second sub-image according to the number of pixels with the gray scale being a preset gray scale value for the first sub-image and the second sub-image after the graying processing and the binarization processing; and carrying out image synthesis processing on image areas with the same image content between the first sub-image and the second sub-image to generate a first image.

The first sub-image is an image acquired by the first wide-angle lens, and the second sub-image is an image acquired by the second wide-angle lens. For the gray image after the binarization processing, the gray value thereof includes 0 and 255, and therefore, the preset gray value is 0 or 255. Of course, the gray scale value in the gray scale image after the binarization process may be represented by "0" and "1", for example, when the gray scale value of the pixel is 0, the gray scale value is represented by "0", and when the gray scale value of the pixel is 255, the gray scale value is represented by "1", which may be selected according to actual requirements.

Optionally, in this embodiment of the application, when a ratio of an image area with the same image content to the whole image area of the target sub-image is smaller than or equal to a preset ratio, image synthesis processing may be performed on the image area with the same image content between the first sub-image and the second sub-image to generate a first image; and when the ratio of the image area with the same image content to the whole image area of the target sub-image is greater than the preset ratio, discarding the first sub-image and the second sub-image.

The target sub-image is a first sub-image or a second sub-image, and the preset proportional value is a proportional value corresponding to the target sub-image, that is: when the target sub-image is a first sub-image, the preset proportion value is a proportion value corresponding to the first sub-image; and when the target sub-image is the second sub-image, the preset proportion value is the proportion value corresponding to the second sub-image. The preset proportion value corresponding to the first sub-image and the preset proportion value corresponding to the second sub-image may be the same or different, for example, when the first wide-angle lens and the second wide-angle lens are the same wide-angle lens and are symmetrically arranged, the preset proportion value corresponding to the first sub-image is the same as the preset proportion value corresponding to the second sub-image.

The preset proportion value is the maximum splicing proportion of the target sub-images when the first sub-images and the second sub-images are spliced.

In order to better understand the above embodiments, the following further explanation is made with a specific example.

It is assumed that the first wide-angle lens and the second wide-angle lens are two identical wide-angle lenses, and the first wide-angle lens and the second wide-angle lens are respectively arranged in a left-right symmetrical manner by deflecting a preset angle in a direction departing from each other, as shown in fig. 2.

As shown in fig. 5, the image composition processing procedure shown in this example may include the following flow:

step 501: a video image captured by the first wide-angle lens (denoted as video image a0, corresponding to the first sub-image) is captured.

Step 502: a video image captured by the second wide-angle lens (denoted as video image b0, corresponding to the second sub-image) is captured.

Step 503: the video image a0 is subjected to a graying process to obtain a video image a1 (i.e., a grayed first sub-image).

Step 504: the video image b0 is grayed to obtain a video image b1 (i.e., the second sub-image after graying).

Step 505: the video image a1 is binarized to obtain a video image a2 (i.e., the first sub-image after the graying and binarization processes).

Step 506: the video image b1 is binarized to obtain a video image b2 (i.e., a second sub-image after the graying and binarization processes are performed).

Step 507: the number of pixels with a gray scale value of 1 in each row of pixels of the statistical video image a2 is recorded as a2[ 1: n ].

In this case, the video image a2 has n columns of pixels, a2[ 1: n ] "1: n "denotes the 1 st column pixel to the n column pixel of the video image a 2. In this example, the gradation values are represented by "0" and "1".

Step 508: the number of pixels with a gray scale value of 1 in each row of pixels of the statistical video image b2 is recorded as b2[1: n ].

In this case, the video image b2 has n columns of pixels, b2[1: n ] "1: n "denotes the 1 st column pixel to the n column pixel of the video image b 2.

Step 509: an image area having the same image content between the video image a2 and the video image b2 is determined according to the number of pixels having a gray scale value of 1 in each column of pixels.

Since the first wide-angle lens and the second wide-angle lens are arranged in bilateral symmetry, when determining an image area with the same image content, it may be determined whether the number of pixels having a gray scale value of 1 in the n-th column of the video image a2 and the 1-th column of the video image b2 is the same.

If the images are the same, stopping the contrast analysis, and determining that the image areas with the same image content between the video image a2 and the video image b2 are: the image area of the nth column of pixels of the video image a2 and the image area of the 1 st column of pixels of the video image b 2.

If not, it is continuously determined whether the number of pixels with gray scale values of 1 in the n-th column of the video image a2 and the 2 nd column of the video image b2 are the same, and the number of pixels with gray scale values of 1 in the n-1 th column of the video image a2 and the 1 st column of the video image b2 are the same.

If all the pixels are the same (i.e. the number of pixels in the n-th column of the video image a2 and the number of pixels in the 2-nd column of the video image b2 are the same, and the number of pixels in the n-1-th column of the video image a2 and the number of pixels in the 1-st column of the video image b2 are also the same), the contrast analysis is stopped, and an image area with the same image content between the video image a2 and the video image b2 is determined as follows: the image areas of the n-1 st column of pixels to the n th column of pixels of the video image a2 and the image areas of the 1 st column of pixels to the 2 nd column of pixels of the video image b 2.

If not, it is continuously determined whether the number of pixels in the n-th column of the video image a2 and the 3-th column of the video image b2 having the gray scale value of 1, the number of pixels in the n-1-th column of the video image a2 and the 2-th column of the video image b2 having the gray scale value of 1, and the number of pixels in the n-2-th column of the video image a2 and the 3-th column of the video image b2 having the gray scale value of 1 are all the same, as shown in fig. 6. And in all cases of the same, stopping the contrast analysis, and determining the image areas with the same image content between the video image a2 and the video image b2 as: the image areas of the n-2 th column of pixels to the n-th column of pixels of the video image a2 and the image areas of the 1 st column of pixels to the 3 rd column of pixels of the video image b 2. Or under the condition that the image areas are not completely the same, continuing to perform the next comparison analysis according to the rule until determining the image areas with the same image content between the video image a2 and the video image b2, or until the proportion value of the image area of the video image a2 currently participating in the comparison analysis in the whole image area is larger than the preset proportion value (or the proportion value of the image area of the video image b2 currently participating in the comparison analysis in the whole image area is larger than the preset proportion value).

For the foregoing comparative analysis process, the specific implementation can be as follows:

for example, a variable i and a variable j may be set, and an initial value 0 may be given to the variable i and an initial value 1 may be given to the variable j. Then, determine whether b2[1: j ] -a2[ n: n-i ] is equal to 0, which can be written as "b 2[1: j ] -a2[ n: n-i ] ═ 0? ".

When i is 0 and j is 1, it is determined whether b2[1:1] -a2[ n:1] is equal to 0, that is, it is determined whether the number of pixels having a gray scale value of 1 in the n-th column of the video image a2 is the same as the number of pixels having a gray scale value of 1 in the 1-st column of the video image b 2.

If the value is equal to 0, it indicates that the image content of the nth column pixel of the video image a2 is the same as the image content of the 1 st column pixel of the video image b2, the contrast analysis is stopped, and the image area with the same image content between the video image a2 and the video image b2 is determined as follows: the image area of the nth column of pixels of the video image a2 and the image area of the 1 st column of pixels of the video image b 2.

If not, judging whether the ratio of the current value of the variable i to the value n is larger than a preset image splicing percentage δ (marked as "i/n > δ. If i/n is less than or equal to δ, which indicates that the preset image splicing percentage between the video image a2 and the video image b2 is not reached, the next comparison analysis is continued, the initial value of the variable i is subjected to plus 1 processing (denoted as i + +), the initial value of the variable j is subjected to plus 1 processing (denoted as j + +), and whether b2[1:2] -a2[ n: n-1] is equal to 0 or not is judged, so as to determine whether the number of gray values in the n-th column of pixels of the video image a2 and the 2-th column of pixels of the video image b2 are 1 and whether the number of gray values in the n-1-th column of pixels of the video image a2 and the 1-th column of pixels of the video image b2 are the same or not. And so on until it is determined that the image areas with the same image content between the video image a2 and the video image b2 are located, or the ratio of the current value of the variable i to the value n is greater than the preset image stitching percentage δ (corresponding to the aforementioned "preset ratio value", in this example, the preset ratio values corresponding to the video image a0 and the video image b0 are the same).

In the case that the ratio of the current value of the variable i to the value n is greater than the preset image stitching percentage δ, the video image a0 and the video image b0 may be discarded.

The image stitching percentage δ may be regarded as a maximum allowable determination logic set to reduce the probability of error in the determination process. The image stitching percentage can be determined in the following manner:

as shown in fig. 7, it is assumed that, at the same photographing distance, the maximum photographing width of a single wide angle lens (i.e., "O" in fig. 7) identical to the first wide angle lens is denoted as L1, the maximum photographing width of the first wide angle lens (i.e., "a" in fig. 7) set at a preset angle is denoted as L2, and the maximum photographing width of the second wide angle lens (i.e., "B" in fig. 7) set at a preset angle is denoted as L3. The total maximum photographing width of the first wide-angle lens and the second wide-angle lens is increased by L4+ L5 compared to the maximum photographing width of a single wide-angle lens, and thus it can be determined that the image stitching percentage between the first sub-image and the second sub-image is: (L2+ L3-L1-L4-L5)/(L1+ L4+ L5).

Step 510: and carrying out image splicing processing and image fusion processing on the video image a0 and the video image b0 according to an image area with the same image content between the video image a2 and the video image b2 to obtain a first image.
