Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is to be understood that the terms "first," "second," and the like in the embodiments of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the designations used as such may be interchanged under appropriate circumstances in order to facilitate describing the embodiments of the application.
The camera switching method provided by the embodiment of the application can be applied to various types of electronic equipment, such as smart phones, tablet computers, cameras, monitoring equipment and the like. The common configuration modes are: a double-shooting system formed by combining a wide-angle camera and a long-focus camera; the three-camera system is formed by combining an ultra-wide-angle camera, a wide-angle camera and a long-focus camera; and a shooting system formed by combining four or more than four cameras with different focal lengths, which is not illustrated in the embodiment of the application.
The wide-angle camera is a lens with a large visual field and a small focal length, and can shoot a scene with a wide visual field generally; the ultra-wide-angle camera is a lens with larger visual field and smaller focal length than a wide-angle lens, and can shoot a scene with larger visual field generally; a telephoto camera is a lens with a small field of view and a large focal length, and can generally shoot scenes with a small field of view but rich details.
At present, when shooting is performed through the electronic device, only one of the plurality of cameras is usually in an on state, and the rest of the plurality of cameras are in an off state. Taking a dual-camera system as an example, when the shooting focal length is less than a certain threshold, the electronic device only starts the wide-angle camera to shoot, the tele camera is in a closed state, and when the shooting focal length is greater than or equal to the threshold, the electronic device starts the tele camera to shoot and simultaneously closes the wide-angle camera. Because a certain time needs to be consumed to start the telephoto camera in the process of switching the shooting mode from the wide-angle camera to the telephoto camera, the shooting picture is easy to jump, and the shooting picture is not smooth enough.
In order to solve the technical problem, in the embodiment provided by the application, after the cameras are started, the cameras are started simultaneously, so that the cameras are all in an open state, and in the process of switching the cameras, a preview image acquired by a certain camera in a shooting interface can be directly switched to a preview image acquired by a target camera without waiting for the target camera to be started, so that the problems of jumping and unsmooth shooting pictures in the switching process of different cameras can be effectively solved.
For better understanding of the embodiments of the present application, an electronic device equipped with a three-camera system including a super wide-angle camera, a wide-angle camera, and a telephoto camera is described below as an example. In the double-shooting system and the shooting system composed of four or more cameras, the switching mode of the cameras is similar to that of the three-shooting system, and details are not repeated in the embodiment of the application.
Referring to fig. 1, fig. 1 is a schematic view of a shooting interface of an electronic device provided in an embodiment of the present application. In fig. 1, the camera of the electronic device is divided into three focal segments, namely [ k1-k2 ], [ k2-k3 ], and [ k3-k4], wherein the values of k1, k2, k3, and k4 increase in sequence. Illustratively, k1 is typically less than 1.0 times the focal length.
When the user adjusts the focal length of the camera to the focal length [ k1-k2), the camera performs photographing using the ultra wide angle camera, when the user adjusts the focal length of the camera to the focal length [ k2-k3), the camera performs photographing using the wide angle camera, and when the user adjusts the focal length of the camera to the focal length [ k3-k4), the camera performs photographing using the tele camera.
Referring to fig. 2, fig. 2 is a schematic flowchart of a camera switching method provided in an embodiment of the present application, and in a possible implementation manner of the present application, the method includes:
s201, responding to a camera starting instruction, starting at least two cameras simultaneously, and displaying preview images acquired by default cameras in the at least two cameras in a shooting interface.
In the embodiment of the application, when the electronic equipment receives a camera starting instruction triggered by a user, all configured cameras are started simultaneously. After each camera is started, sending a preview request to a default camera, acquiring a preview image acquired by the default camera, and displaying the preview image acquired by the default camera in a shooting interface.
In the process of displaying the preview image acquired by the default camera in the shooting interface, the image data acquired by other cameras except the default camera can be directly selected to be discarded without any processing.
After the camera is started, if the default focal length of the camera is located in a focal length [ k2-k3), a preview request is issued to the wide-angle camera, and the wide-angle camera transmits the acquired image data to a shooting interface for display.
S202, responding to the focal length adjusting instruction, and detecting whether the adjusted focal length meets the camera switching condition.
In the shooting process, a user can click or slide the focal length adjusting control to adjust the focal length of the camera on the shooting interface according to the actual framing requirement, or adjust the focal length of the camera through the zooming-in/zooming-out sliding operation of two fingers in the shooting interface, so that the camera is controlled to be switched among different cameras.
When the electronic equipment detects a focal length adjusting instruction triggered by a user, responding to the focal length adjusting instruction, and detecting whether the adjusted focal length meets a camera switching condition or not in real time. When detecting that the focal length of the camera is adjusted from one focal section to another focal section, determining that the adjusted focal length meets the camera switching condition
And S203, when the adjusted focal length meets the camera switching condition, acquiring a preview image acquired by the target camera corresponding to the adjusted focal length, and switching the preview image acquired by the first camera currently displayed in the shooting interface into the preview image acquired by the target camera.
In the embodiment of the application, if the focal length of the camera is adjusted from the focal length [ k2-k3 ] to [ k3-k4] by the user, a preview request is sent to the telephoto camera head, so that the telephoto camera transmits the acquired image data to the shooting interface for display, and meanwhile, the issuing of the preview request to the wide-angle camera is stopped.
And the first camera is a camera corresponding to the preview image displayed in the shooting interface before the camera is switched. For example, when the camera is switched from the wide-angle camera to the tele-camera, the first camera is the wide-angle camera; when the camera is switched to the wide-angle camera from the long-focus camera, the first camera is the long-focus camera.
According to the camera switching method provided by the embodiment of the application, after the camera is started, each camera on the electronic equipment is in the open state, so that in the process of switching the cameras, the preview image currently displayed in the shooting interface can be directly switched into the preview image collected by the target camera without waiting for the target camera to be started, and the problem that the shooting pictures are not smooth in the switching process of different cameras can be effectively solved.
Based on the content described in the foregoing embodiment, in a feasible implementation manner of the present application, when the electronic device receives a camera start instruction, the electronic device simultaneously starts an image sensor (sensor) corresponding to each camera, that is, the image sensor corresponding to each camera is powered on, so that the image sensor corresponding to each camera can acquire a preview image.
After image sensors corresponding to all the cameras are started, sending a preview request to an image sensor corresponding to a default camera, wherein the preview request is used for requesting that a preview image acquired by the image sensor corresponding to the default camera is sent to a shooting interface for displaying; when a preview image sent by an image sensor corresponding to the default camera is received, the received preview image can be output to a shooting interface for display.
The image sensor corresponding to the default camera can directly discard the image data acquired by the image sensor.
It can be understood that, when receiving a camera start instruction, the electronic device in the present application only starts the image sensors of the cameras at the same time, and then issues a preview request to only one of the cameras, so that some data processing related to image preview and the load of the CPU are only for one of the cameras, and thus the power consumption of the whole shooting system can still be close to the power consumption when only one camera is started.
In the camera switching method provided by the embodiment of the application, after the camera is started, the image sensors corresponding to the cameras on the electronic device are started at the same time, but only the preview request is sent to the image sensor corresponding to the default camera, and the preview request does not need to be issued to the image sensors corresponding to the cameras at the same time, so that the power consumption of a CPU and a memory can be effectively reduced.
Based on the description in the foregoing embodiments, in a possible implementation manner, after displaying the preview image captured by the default camera in the shooting interface, the electronic device responds to a focus sliding adjustment operation, and when the focus sliding adjustment operation adjusts the focus of the camera from one focus segment to another adjacent focus segment, determines that the adjusted focus satisfies the camera switching condition.
For better understanding of the embodiment of the present application, referring to fig. 3, fig. 3 is a schematic view of a scene of adjusting the focal length by sliding in the embodiment of the present application. In FIG. 3, the user may slide the focus control 30 from the focal segment [ k2-k3) to the focal segment [ k3-k4] by finger sliding.
When the user slides and adjusts the focal length of the camera from the focal section [ k2-k3 ] to the focal section [ k3-k4], the adjusted focal length can be determined to meet the camera switching condition at the moment when the focal length is changed from being less than k3 to being more than or equal to k 3.
It can be understood that, during the sliding adjustment of the focal length of the camera from the focal length [ k2-k3 ] to the focal length [ k3-k4], if the sliding speed is fast and the difference between the preview images before and after switching is large, the transition of the preview image displayed in the shooting interface during switching is inevitably caused. In order to solve the problem, in the embodiment of the application, when the adjusted focal length meets the camera switching condition, a preview request is sent to a target camera corresponding to the adjusted focal length, and the preview request is used for requesting to send a preview image acquired by the target camera to a shooting interface for displaying; and when the preview image sent by the target camera is received, matching the preview image currently displayed in the shooting interface with the preview image sent by the target camera, and if the matching is successful, switching the preview image currently displayed in the shooting interface into the preview image acquired by the target camera.
Illustratively, when a user slidingly adjusts the focal length of the camera from a focal length [ k2-k3 ] to a focal length [ k3-k4], a preview request is sent to the tele camera, when a preview image sent by the tele camera is received, a first time stamp of a last acquired preview image of the wide camera currently displayed in a shooting interface and a second time stamp of the last acquired preview image of the tele camera are acquired, and then whether the difference value between the first time stamp and the second time stamp is smaller than a preset threshold value is judged; and when the difference value between the first time stamp and the second time stamp is smaller than the preset threshold value, switching the preview image acquired by the first camera currently displayed in the shooting interface into the preview image acquired by the tele-camera, and stopping sending the preview request to the wide-angle camera.
Optionally, when the difference between the first timestamp and the second timestamp is equal to or greater than the preset threshold, a preview image with the smallest difference between a frame of timestamp and the first timestamp may be determined in a plurality of frames of preview images recently acquired by the telephoto camera, and then the preview image acquired by the first camera currently displayed in the shooting interface is switched to the preview image.
According to the camera switching method provided by the embodiment of the application, in the camera switching process, through matching the preview images acquired by the two cameras, the smoothness of a shooting interface in the camera switching process can be further ensured.
Based on the content described in the foregoing embodiments, in another possible implementation manner of the present application, after the preview image captured by the default camera is displayed in the shooting interface, the electronic device responds to a focus click adjustment operation, and when the focus click adjustment operation adjusts the focus of the camera from one focal segment to another focal segment, it is determined that the adjusted focus satisfies the camera switching condition.
That is, in the embodiment of the present application, the user may adjust the focal length of the camera by clicking the shooting interface. For example, when the user needs to adjust the focal length of the camera from focal segment [ k1-k2) directly to focal segment [ k3-k4], a location in focal segment [ k3-k4] can be clicked directly to adjust the focal length of the camera to focal segment [ k3-k4 ].
For better understanding of the embodiment of the present application, referring to fig. 4, fig. 4 is a schematic view of a scene in which a focal length is adjusted by clicking in the embodiment of the present application. In FIG. 4, the user can adjust the focal length of the camera to the focal segment [ k3-k4] by clicking any position in the focal segment [ k3-k4] with a finger.
When the electronic equipment detects that the focal length of the camera is adjusted from a focal length [ k1-k2 ] to a focal length [ k3-k4] through click operation by a user, a preview request is sent to the tele camera, and the preview request is used for requesting to send a preview image acquired by the tele camera to a shooting interface for displaying; and when a preview image sent by the tele camera is received, outputting the received preview image to a shooting interface for displaying, and stopping issuing a preview request to the ultra-wide camera. Therefore, the preview image acquired by the ultra-wide-angle camera currently displayed in the shooting interface can be switched to the preview image acquired by the tele-camera.
It can be understood that, in the camera switching method provided in the embodiment of the present application, only the preview image data collected by one camera is transmitted without switching the cameras, so that power consumption of the camera can be effectively reduced, and meanwhile, in the process of needing to switch the cameras, the preview image currently displayed in the shooting interface can be directly switched to the preview image collected by the target camera without waiting for the target camera to start, so that the problem that the shooting picture is not smooth in the switching process of different cameras can be effectively avoided.
Based on the content described in the foregoing embodiment, an embodiment of the present application further provides a camera switching device, which is applied to the electronic device described in the foregoing embodiment, and referring to fig. 5, fig. 5 is a schematic diagram of program modules of the camera switching device provided in the embodiment of the present application.
