The image capturing method, the image capturing apparatus, and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides an image capturing method, which includes the following S101 and S102.
S101, the image shooting device receives a first input of a user.
Optionally, the first input may be a touch input, a gesture input, or a voice input of the user. For example, the touch input is a click input of a target control by a user, and the target control is a control for touch shooting. Of course, the first input may also be a physical key input or other inputs with a function of triggering shooting, which is determined according to actual situations, and this is not limited in this embodiment of the present application.
S102, the image shooting device responds to the first input and controls a rear camera of the electronic equipment to shoot a target object to obtain a first image.
Wherein the imaging direction of the first image coincides with the face direction of the user.
Optionally, in this embodiment of the application, since the electronic device may be provided with M rear cameras, where M is a positive integer, the rear camera used for shooting the target object may be a camera of the M rear cameras, and thus the number of the rear cameras used for shooting the target object may be one or more, which may be determined specifically according to an actual situation, and this is not limited in this embodiment of the application.
For example, when the number of the rear cameras for shooting the target object is one, the rear cameras may be a main camera or a wide-angle camera, and the like, that is, the first image is an image captured by the main camera or the wide-angle camera; when the number of the rear cameras for photographing the target object is two, the rear cameras may include a main camera and a wide-angle camera, that is, the first image is an image collected by the main camera and the wide-angle camera.
Optionally, in the embodiment of the present application, the target object may be any living body and non-living body. For example, the target object may be a person, a plant, an automobile, a food or a document, and so on. In addition, the first image may be a shot photograph or video, and the first image includes an image of the target object.
Optionally, the "imaging direction of the first image" refers to: the electronic device outputs the direction of the first image after shooting the target object. In addition, in the embodiment of the present application, the face direction of the user is an imaging direction of the user in an image captured by a front camera of the electronic device. Reference may be made to the following description of the embodiments, which are not repeated herein.
Illustratively, when the electronic device is vertically placed, the imaging direction of the first image is a direction from the bottom to the top of the electronic device; when the electronic device is placed horizontally, the imaging direction of the first image is from the lower side edge to the upper side edge of the electronic device.
Optionally, in this embodiment of the application, the fact that the imaging direction of the first image is consistent with the direction of the face of the user specifically means: the imaging direction of the first image is kept parallel to the face direction of the user, or the imaging direction of the first image is consistent with the face direction of the user within a reasonable angle error range. The angle error range may be between zero degrees and a predetermined angle.
It should be noted that, for different placement directions of the electronic device relative to the user, due to the change of the placement direction of the electronic device, a shooting angle of the rear camera of the electronic device for shooting the target object also changes accordingly, so that the camera may adjust a direction of acquiring an image of the target object, that is, an image acquisition direction of the first image is different, and further, an imaging direction of the target object in the first image is also different.
It can be understood that, because the imaging direction of the first image is consistent with the face direction of the user, the first image output by the electronic device is consistent with the target object in the real view angle of the user, and therefore, no matter how the placement posture of the electronic device changes, the image direction of the target object acquired by the rear camera of the electronic device can be adjusted in real time, so as to ensure that the first image obtained by shooting is consistent with the target object actually seen by the user.
For example, the image capturing device is a mobile phone, and the rear camera is a main camera. Assuming that the user holds the phone sideways and wants to take a meal on the table, the user can click the take button on the phone. After the mobile phone receives the click input (i.e. the first input), the mobile phone can respond to the click input and control the rear main camera to obtain a food photo, wherein the imaging direction of the food photo is consistent with the face direction of the user, so that the food photo is in line with the expectation of the user.
Optionally, after S102, the image capturing method provided in the embodiment of the present application may further include: the image shooting device controls the electronic equipment to save the first image.
The embodiment of the application provides an image shooting method, because a user can trigger a rear camera of an electronic device to shoot a target object through input to obtain a first image with an imaging direction consistent with the face direction of the user, the display direction of the first image is consistent with the direction of the target object actually seen by the target user, and therefore the problem that the shot image is turned over by 180 degrees or 90 degrees is solved, namely the display direction of the shot image is consistent with the expected direction of the user.
Alternatively, the above S102 may be implemented by the following S102A, S102B, and S102C.
S102A, the image shooting device responds to the first input, and a second image is collected through a front camera of the electronic equipment.
Wherein the second image is an image including a face of the user.
Optionally, in this embodiment of the application, the electronic device may be provided with N front-facing cameras, where N is a positive integer. The front-facing camera used for collecting the second image is a camera of the N front-facing cameras, that is, the number of the front-facing cameras may be one or more. Further, in the case where the number of the front cameras is plural, the kind of each of the plural front cameras may be different.
Optionally, in this embodiment of the application, the second image may be a preview image of the user acquired by the front-facing camera, a picture obtained by the user taken by the front-facing camera, or a video image of the user acquired by the front-facing camera. For example, the second image is a self-photograph of the user.
Alternatively, the above S102A may be implemented by the following S102a1 and S102a 2. Accordingly, S102a2 can be specifically realized by S102A3 described below.
S102a1, the image capture device obtains a horizontal attitude angle in response to the first input.
Wherein, the horizontal attitude angle is an included angle between the rear camera and a horizontal plane.
It should be noted that, when a user triggers the rear camera of the electronic device to shoot, the horizontal attitude angle of the state of the electronic device, that is, the included angle between the plane where the rear camera of the electronic device is located and the horizontal plane, may be detected by a three-axis gyroscope configured in the electronic device.
Optionally, in the foregoing embodiment, the horizontal attitude angle is detected when the user triggers the rear camera of the electronic device to shoot the target object, and the image shooting method provided in the embodiment of the present application may further provide another implementation: in the case where a camera application of the electronic device is run and the rear camera is in a shooting state, a horizontal attitude angle of the state in which the electronic device is located is periodically detected.
S102A2, the image shooting device collects a second image through the front camera under the condition that the horizontal attitude angle is smaller than the preset angle.
Optionally, the preset angle may be factory set for the electronic device or user-defined set for the user. The method can be determined according to actual conditions, and is not limited in the embodiment of the application. For example, the preset angle is 10 degrees.
It should be noted that, in the embodiment of the present application, if it is detected that the horizontal attitude angle of the rear camera of the electronic device is relatively large, the gyroscope in the electronic device may trigger the electronic device to automatically adjust the image acquisition direction of the target object by the rear camera, so as to ensure that the image output by the electronic device is consistent with the direction in which the user actually sees the target object, that is, the image of the target object is acquired by the rear camera, so that the problem that the image is easily misaligned by 90 degrees or 180 degrees from the desired direction of the user is not likely to occur; if the horizontal attitude angle of the rear camera of the electronic equipment is detected to be close to horizontal (namely the horizontal attitude angle is small), the rear camera is used for collecting the image of the target object, the problem that the image is deviated from the expected direction of a user by 90 degrees or 180 degrees is easy to occur, at the moment, the front camera of the electronic equipment can be started, and a second image is collected through the front camera.
It can be understood that, since the horizontal attitude angle can be obtained, it can be determined whether the front camera of the electronic device needs to be operated to acquire the second image of the target user by judging whether the horizontal attitude angle is smaller than the preset angle, so that the second image is acquired by the front camera of the electronic device whether the horizontal attitude angle is smaller than the preset angle. Therefore, the running resources of the electronic equipment can be effectively utilized, unnecessary resource waste is saved, and the working efficiency is improved.
S102B, the image shooting device determines the target placing posture according to the face direction of the user.
And the face direction is the imaging direction of the user in the second image. The target placement posture is a placement posture of the electronic device relative to the user.
It should be noted that, because the electronic device is placed in different directions relative to the user, the imaging directions of the user in the second image, which are acquired by the front camera of the electronic device, are also different, so that the imaging directions of the target user in the second image are also different, that is, the face directions are different. It is to be understood that, in the case of determining the face direction of the target user, the target placement posture may be determined in accordance with the face direction.
Specifically, if the imaging direction of the user in the second image is a direction from the bottom to the top of the electronic device, that is, the face direction of the user is a direction from the bottom to the top of the electronic device, the electronic device is vertically placed relative to the user; if the imaging direction of the user in the second image is a direction from the lower side to the upper side of the electronic device, that is, the face direction of the user is a direction from the lower side to the upper side of the electronic device, the electronic device is placed transversely with respect to the user.
Optionally, after the above S102A and before S102B, the image capturing method provided in the embodiment of the present application may further include S102D described below.
S102D, the image shooting device identifies the facial feature distribution information of the user in the second image to obtain the face direction.
And the face direction is the imaging direction of the user in the second image.
Optionally, the facial feature distribution information includes feature distribution information of the eyes, nose, mouth, and the like of the target user. Specifically, the face image in the second image may be subjected to image recognition by a face recognition technique, and then the face direction of the user is obtained from the distribution information of the recognized eyes, nose, and mouth.
It can be understood that, because the front-facing camera can collect the second image of the user in real time, the image shooting device can identify the facial feature distribution information of the user in the second image, and obtain the facial direction according to the facial feature distribution information, and further judge the placing posture of the electronic equipment relative to the user according to the facial direction. The method provides basis for determining the target placement posture of the electronic equipment.
S102C, the image shooting device controls a rear camera of the electronic equipment to shoot the target object according to the target placement direction, and a first image which is consistent with the imaging direction of the user in the second image is obtained.
Optionally, the target placement direction is associated with a target placement posture of the electronic device. Specifically, the target placement direction may include an up-down relationship in which the electronic device is in a landscape placement posture or a portrait placement posture with respect to the target user, and the electronic device is in the placement posture. For example, as shown in fig. 2 (a), the cellular phone is vertically placed with respect to the user in the a-B direction, i.e., from bottom to top (i.e., from bottom to top).
Illustratively, the image capturing device is a mobile phone, and the horizontal attitude angle is 10 degrees. As shown in fig. 2 (a), if a user wants to shoot a scene in which a child has a firecracker at an angle close to the horizontal direction using a mobile phone, the user can click on a control 01 displayed on the mobile phone. After the mobile phone receives a click input (i.e., a first input) of a user, in response to the click input, the mobile phone may acquire that an included angle between a rear camera of the mobile phone and a horizontal plane is 8 degrees, that is, a horizontal attitude angle is 8 degrees. Then, since the horizontal attitude angle is smaller than the preset angle, the mobile phone can operate the front camera, and capture the preview image 02 (i.e., the second image) of the user through the front camera. Next, the cell phone can recognize distribution information of the eyes, nose, and mouth of the face of the user included in the preview image 02, resulting in the face direction of the user from a to B as shown in (a) in fig. 2. Then, the mobile phone can determine that the mobile phone is vertically placed relative to the user according to the imaging direction of the user in the preview image 02 from a to B, and the mobile phone is placed from the bottom frame to the top frame in the vertical direction according to the direction from a to B. Finally, as shown in fig. 2 (B), a rear camera with a vertically placed mobile phone shoots a scene in which a child shoots a firecracker according to a direction from a to B, and an image 03 (i.e., a first image) is obtained, wherein an image acquisition direction of the image 03 is consistent with an imaging direction of a target object on a retina of the user.
Illustratively, the image capturing device is a mobile phone, and the horizontal attitude angle is 10 degrees. As shown in fig. 3 (a), if the user wants to shoot a scene in which a child has a firecracker at an angle close to the horizontal direction using a mobile phone, the user can click on a control 01 displayed on the mobile phone. After the mobile phone receives a click input (i.e., a first input) of a user, in response to the click input, the mobile phone may acquire that an included angle between a rear camera of the mobile phone and a horizontal plane is 5 degrees, that is, a horizontal attitude angle is 5 degrees. Then, since the horizontal attitude angle is smaller than the preset angle, the mobile phone can operate the front camera, and capture the preview image 04 (i.e., the second image) of the user through the front camera. Next, the mobile phone can recognize distribution information of the eyes, nose, and mouth of the face of the user included in the preview image 04, resulting in the face direction of the user from a to B as shown in (a) in fig. 3. Then, the mobile phone can determine that the mobile phone is placed horizontally relative to the user according to the imaging direction of the user in the preview image 03 from a to B, and the mobile phone is placed in the vertical direction from the bottom side frame to the top side frame along the direction from a to B. Finally, as shown in fig. 3 (B), the rear camera of the mobile phone placed transversely shoots the scene (i.e., the target object) of the firecracker set by the child in the direction from a to B, and an image 05 (i.e., a first image) is obtained, i.e., the image capturing direction of the image 05 is consistent with the direction in which the target object is imaged on the retina of the user.
It can be understood that the photographing direction of the rear camera to the target object is adjusted, so that the composition of the target object is consistent with the placing direction of the electronic equipment relative to the user, and the up-down relation between the imaging direction and the placing direction of the electronic equipment is consistent, and the effect that the image output by the electronic equipment is consistent with the real object seen by the user is further achieved.
According to the image shooting method provided by the embodiment of the application, one image of a user can be collected through the front camera of the electronic equipment, and the target placing direction of the electronic equipment is determined according to the face direction of the user in the image, so that the target placing direction can be determined by the image shooting device according to the image collected by the front camera in real time, the image collecting direction of the rear camera of the electronic equipment to the target object is continuously adjusted according to the target placing direction, and the obtained imaging direction of the target object is ensured to be in accordance with the expectation of the user.
Optionally, after the user triggers the electronic device to shoot the target object to obtain the first image, the user may view the first image through the electronic device according to an actual requirement. For example, referring to fig. 1, as shown in fig. 4, after S102, the image capturing method provided in the embodiment of the present application may further include S103 and S104 described below.
And S103, receiving a second input by the image shooting device.
The second input is an input for triggering display of the first image.
Optionally, the second input is a touch input, a gesture input, or a voice input of the user. For example, the touch input is a user click input on a thumbnail of the first image. Of course, the second input may also be other possible inputs, which are determined according to practical situations, and this is not limited in this embodiment of the application.
And S104, the image shooting device responds to the second input and displays the first image according to the face direction.
Optionally, in the embodiment of the present application, one possible case is: the face direction is determined when the first image is shot in a triggering mode, and the first image is displayed according to the face direction and is irrelevant to the placement posture of the electronic equipment; another possible scenario is: the face direction is determined in real time when the first image is triggered to be displayed, and the face direction is determined when the electronic device is in the current placement posture, namely, the first image is displayed according to the face direction and is related to the placement posture of the electronic device. The method can be determined according to actual conditions, and is not limited in the embodiment of the application.
Illustratively, the image capturing device is taken as a mobile phone. As shown in fig. 5 (a), the mobile phone displays an album including thumbnail 1 (i.e., a thumbnail of the first image), thumbnail 2, thumbnail 3, and thumbnail 4. If the user wants to view the first image, the user may click on thumbnail 1. After the cell phone receives the click input, in response to the click input, as shown in fig. 5 (B), the cell phone vertically displays the image 06 (i.e., the first image) in the direction of lower a to upper B. I.e. the display orientation of the image 06 coincides with the orientation actually seen by the user.
Illustratively, the image capturing device is taken as a mobile phone. As shown in fig. 6 (a), the mobile phone displays an album including thumbnail 1, thumbnail 2 (i.e., thumbnail of first image), thumbnail 3, and thumbnail 4. If the user wants to view the first image, the user can click on thumbnail 2. After the cell phone receives the click input, in response to the click input, as shown in fig. 6 (B), the cell phone displays the image 07 (i.e., the first image) laterally in the direction of lower a to upper B. I.e. the display orientation of the image 07 coincides with the orientation actually seen by the user.
According to the image shooting method provided by the embodiment of the application, the user can trigger the display of the first image according to the imaging direction of the target object on the retina of the target user according to actual needs, so that the first image is consistent with the actual viewing direction of the user, and the user can quickly view the image meeting the requirements.
It should be noted that, in the image capturing method provided in the embodiment of the present application, the executing subject may be an image capturing apparatus (for example, the image capturing apparatus is an electronic device or a control module in the electronic device), or a control module in the image capturing apparatus for executing the image capturing method. The image capturing apparatus provided in the embodiment of the present application is described with an example in which an image capturing apparatus executes an image capturing method.
As shown in fig. 7, the embodiment of the present application provides an image capturing apparatus 200, which may include a receiving module 201 and a control module 202. The receiving module 201 may be configured to receive a first input of a user.

The determining module 204 may be configured to determine a target placement posture according to a face direction of the user, where the face direction is an imaging direction of the user in the second image, and the target placement posture is a placement posture of the electronic device relative to the user. The control module 202 is specifically configured to control a rear camera of the electronic device to shoot a target object according to a target placement direction, so as to obtain a first image that is consistent with an imaging direction of a user in the second image.
Optionally, the image capturing apparatus may further include the recognition module 205. The recognition module 205 may be configured to recognize the facial feature distribution information of the user in the second image to obtain the facial direction before the determination module 204 determines the target placement posture according to the facial direction of the user.
Optionally, the image capturing apparatus may further include an acquisition module 206. The obtaining module 206 may be configured to obtain a horizontal attitude angle, where the horizontal attitude angle is an included angle between a plane where the rear camera is located and a horizontal plane. The collecting module 203 may be specifically configured to collect the second image through the front camera under the condition that the horizontal attitude angle obtained by the obtaining module 206 is smaller than the preset angle.
Optionally, the image capturing apparatus may further include a display module 207. The receiving module 201 may be further configured to receive a second input, where the second input is an input triggering the display of the first image.
