Specifically, fig. 1 shows a flowchart of an image generation method provided in an embodiment of the present application, which may be applied to a terminal device.
The image generation method may include:
step S101, if it is detected that the current zoom multiple meets a preset condition, acquiring first image data corresponding to a first lens according to the current zoom multiple, and starting and configuring a second lens, wherein the first lens is in a started state.
In the embodiment of the present application, the current zoom magnification may be determined based on a digital zoom magnification and/or an optical zoom magnification. In some cases, the user may adjust the current zoom magnification by adjusting the zoom ratio of the current preview image through a specific gesture, a button in a display interface of the terminal device, or the like. The preset condition can be determined according to the actual scene requirement. For example, in some application scenarios, the preset condition may be that the current zoom multiple is in a preset value interval; alternatively, the preset condition may be that the current zoom multiple has a changing trend to a preset trend, for example, the current zoom multiple is continuously increased with respect to the zoom multiple of the previous X frame preview image until being greater than a specified value, and the like.
The types of the first lens and the second lens may be different or the same. Specifically, the determination may be made according to a type of a lens and a control manner on the terminal device. The number of the first shots and the number of the second shots may also be determined according to an actual application scenario. For example, at present, a wide-angle lens, a telephoto lens, an ultra-wide-angle lens, an infrared lens, and/or the like may be included in the terminal device. In different application scenes, the terminal device can acquire image data of one or more than two lenses according to the need and preset information to be used for generating images. For example, in the embodiment of the present application, the type of the first lens may include a wide-angle lens, and the type of the second lens may include a telephoto lens.
When the current zoom multiple meets a preset condition, in order to obtain a better preview image effect, the terminal device needs to acquire first image data of the first lens and second image data of the second lens to generate a preview image. In the embodiment of the present application, before the current zoom factor is changed to meet the preset condition, the first lens may be already in use, so that the first lens is already in an operating state, but the second lens is not started. Therefore, in the embodiment of the present application, after it is detected that the current zoom multiple meets the preset condition, the second lens may be started and configured, and meanwhile, the first image data may be acquired according to the previous configuration of the first lens. The first lens is a lens that has been activated, so that the first image data output by the first lens can be continuous and stable image data.
In some embodiments, the obtaining first image data corresponding to the first lens according to the current zoom multiple and starting and configuring the second lens if the current zoom multiple is detected to meet the preset condition includes:
and if the current zooming multiple is detected to be changed from being not more than the first numerical value to being more than the first numerical value and being less than the second numerical value, acquiring first image data corresponding to the first lens according to the current zooming multiple, and starting and configuring the second lens.
Wherein the first and second values may be preset. For example, the first value may be 1 times, and the second value may be 5 times.
Step S102, in the process of starting and configuring the second lens, generating a first preview image according to the first image data.
In the embodiment of the application, because the first lens is in the started state, the acquired first image data can be continuously and stably output, and therefore, the situation that the image data cannot be acquired because a certain time length is required for starting and configuring the second lens, and the preview image cannot be output in a certain time length to cause blocking is avoided. For example, the first preview image may be generated and displayed in real time according to the first image data.
In some embodiments, the second shot may be started and configured in a background of the terminal device to avoid interfering with the generated and displayed first preview image.
In some embodiments, a pipeline (pipeline) for acquiring image data may be controlled by a Multi Camera Controller (MCC) in the terminal device, so as to generate the first preview image according to the first image data during the process of starting and configuring the second lens. For example, in the process of starting and configuring the second lens, the number of pipelines for acquiring image data may be made to be consistent with the number of first lenses, and each pipeline may acquire first image data of one first lens respectively and generate a first preview image according to each first image data. At this time, the MCC may control the source of the image data by controlling the number of the pipes and the lenses associated with the pipes, so as to ensure that the operation of starting and configuring the second lens does not interfere with the operation of generating and displaying the first preview image in the process of starting and configuring the second lens.
Step S103, after the second lens configuration is completed, generating a second preview image according to second image data of the second lens and the first image data, where the second lens configuration completion indicates that the second lens can output second image data.
In this embodiment, the second preview image and the first preview image may be preview images generated according to different image data. In some examples, the second preview image may be generated and displayed in real-time from the second image data and the first image data. For example, after the second lens configuration is completed, corresponding notification information may be sent to a control module such as an MCC to notify the MCC to acquire second image data output by the second lens; or, after the second lens configuration is completed, the preset status bit may also be adjusted to a designated status, and at this time, the MCC may determine that the second lens configuration is completed after monitoring that the preset status bit is in the designated status, so as to acquire the second image data output by the second lens.
In this embodiment of the application, after the second lens is configured, generating a second preview image according to the second image data of the second lens and the first image data includes:
step S201, after the second lens configuration is completed, detecting the current zoom multiple again;
step S202, if the redetected current zoom multiple accords with the preset condition, a second preview image is generated according to the second image data of the second lens and the first image data based on the redetected current zoom multiple.
In the embodiment of the application, in order to improve the effect of the preview image, the current zoom multiple may be detected again after the second lens configuration is completed, so as to select image data acquired by a proper lens to generate the preview image, thereby avoiding a judgment deviation caused by a quick operation of a user.
In some embodiments, if the redetected current zoom multiple does not meet the preset condition, the generation manner of the preview image may be determined according to the redetected current zoom multiple.
In the embodiment of the present application, there may be a plurality of specific ways of generating the second preview image according to the second image data of the second lens and the first image data. For example, Spatial Alignment Transform (SAT), enhancement, denoising, sharpening, and other image processing may be performed on the second image data and the first image data to obtain the second preview image.
In the embodiment of the application, after the second lens can output the second image data, the second preview image can be generated according to the stably output second image data and the first image data, so that the preview image can still be smoothly output under the condition of lens switching, and the situation of blocking cannot occur.
Optionally, in some embodiments, if it is detected that the current zoom multiple meets a preset condition, acquiring first image data corresponding to the first lens according to the current zoom multiple, and starting and configuring the second lens includes:
if the current zoom multiple is detected to accord with the preset condition, starting and configuring the second lens, and setting the number of channels for acquiring image data as N, wherein N is the number of the first lenses;
respectively acquiring first image data corresponding to the N first lenses through the N channels;
after the second lens configuration is completed, generating a second preview image according to second image data of the second lens and the first image data, including:
after the second lens is configured, setting the number of channels for acquiring image data to be N + M, wherein M is the number of the second lenses;
respectively acquiring first image data of N first lenses and second image data of M second lenses through the N + M channels;
and generating a second preview image according to the first image data and the second image data.
In this embodiment of the present application, the pipeline (pipeline) may be used to implement a certain group of lens functions, for example, to implement a process of acquiring image data to generate a preview image, where the process may include a hardware information stream, and the like. In some embodiments, it may be that the Generate readimerequest service sends, to the MCC, indication information indicating that the current zoom multiple meets the preset condition, and after the MCC acquires the indication information indicating that the current zoom multiple meets the preset condition, the MCC controls the number of the pipes and the shots associated with the pipes, so as to control a source of image data for generating the preview image.
In the embodiment of the application, in the process of starting and configuring the second lens, the number of pipelines for acquiring image data can be consistent with the number of the first lenses, each pipeline can acquire first image data of one first lens respectively, and then a first preview image is generated according to each first image data, so that it can be ensured that in the process of starting and configuring the second lens, the operation of starting and configuring the second lens does not interfere with the operation of generating and displaying the first preview image.
Optionally, in some embodiments, the image generating method further includes:
setting a preset state bit as a first state bit in the process of starting and configuring the second lens;
the setting the number of channels for acquiring image data to be N + M after the second lens configuration is completed includes:
after the second lens configuration is completed, setting the preset state bit as a second state bit;
and after the preset state bit is detected to be changed from the first state bit to the second state bit, setting the number of channels for acquiring the image data to be N + M.
In this embodiment of the application, the starting and configuration conditions of the second lens can be marked by the preset status bit, so that modules such as an MCC can determine whether the configuration of the second lens is completed by monitoring the preset status bit.
Optionally, in some embodiments, the first lens comprises a wide-angle lens, and the second lens comprises a telephoto lens;
if the current zoom multiple is detected to meet the preset condition, starting and configuring the second lens, and setting the number of channels for acquiring the image data to be N, wherein the method comprises the following steps:
and if the current zoom multiple is detected to meet the preset condition, starting and configuring the telephoto lens, closing a channel for acquiring third image data of the third lens, and enabling N channels to be in an open state, wherein the N channels are used for respectively acquiring N first image data of the wide-angle lens.
In the embodiment of the present application, before the current zoom multiple meets the preset condition, the lens that the terminal device enables may include a wide-angle lens and an ultra-wide-angle lens, and therefore, after detecting that the current zoom multiple meets the preset condition, the lens needs to be switched. Specifically, a channel for acquiring third image data of the ultra-wide-angle lens may be closed, and N channels may be in an open state, where the N channels are used to acquire N first image data of the wide-angle lens, respectively, so that the first preview image may be generated only according to the first image data acquired by the wide-angle lens.
In the embodiment of the application, the switching of the lens can be realized in a software mode by controlling the opening and closing of the channel for acquiring the image data, so that the operation control on hardware is reduced, the service life of the hardware is prolonged, and the processing speed can be increased.
A specific application of the present application is described below as a specific example.
In some examples, when a user sets a zoom multiple of the terminal device to be not less than 0.6 and less than 1, the terminal device may acquire image data of an ultra-wide-angle lens and image data of a wide-angle lens to generate a preview image, where the ultra-wide-angle lens may be a main lens. When the zoom multiple of the terminal equipment is equal to 1, the terminal equipment can acquire the image data of the ultra-wide-angle lens and the image data of the wide-angle lens to generate a preview image, wherein the wide-angle lens can be a main lens. Therefore, when the zoom factor of the terminal device is not less than 1, the terminal device may simultaneously acquire the image data of the ultra-wide-angle lens and the image data of the wide-angle lens. And when the zoom multiple of the terminal device is greater than 1 and less than 5, in order to obtain a better preview image effect, the terminal device may acquire image data of the wide-angle lens and image data of the telephoto lens to generate a preview image.
Therefore, if it is detected that the current zoom multiple is changed from not greater than 1 to greater than 1 and less than 5, the lens of the terminal device needs to be switched. Accordingly, the preset condition may be set to change the current zoom multiple from not more than 1 to more than 1 and less than 5.
At the moment, the source of the image data acquired by the terminal equipment is switched to the wide-angle lens and the telephoto lens from the wide-angle lens and the ultra-wide-angle lens. Wherein the wide-angle lens is already actuated, and therefore the first image data of the wide-angle lens can be continuously acquired, while the telephoto lens needs to be actuated and configured. If the terminal device simultaneously acquires the image data of the wide-angle lens and the telephoto lens to generate a preview image, the terminal device needs to wait for the telephoto lens to finish starting and configuration, so that the preview image of the terminal device is jammed. In the embodiment of the present application, in the process of starting and configuring the telephoto lens, a channel for acquiring the third image data of the ultra-wide-angle lens may be closed, and N channels are in an open state, where N channels are used to acquire N first image data of the wide-angle lens, respectively, so that the first preview image may be generated only according to the first image data acquired by the wide-angle lens. After the telephoto lens configuration is completed, the number of channels for acquiring image data may be set to N + M, and the first image data of the first lens and the second image data of the M second lenses are acquired through the N + M channels, respectively, and then a second preview image is generated according to the first image data and the second image data. Therefore, the preview image can still be generated in real time in the process of lens switching, and the phenomenon of jamming caused by the starting and the configuration of the telephoto lens is avoided.
It should be noted that the above-mentioned examples are only illustrative of the embodiments of the present application, and are not limiting.
In the embodiment of the application, if the current zoom multiple is detected to meet the preset condition, first image data of a first lens is acquired according to the current zoom multiple, and meanwhile, a second lens is started and configured, so that a first preview image is generated according to the first image data in the process of starting and configuring the second lens; at this time, because the first lens is in the started state, the acquired first image data can be continuously and stably output, so that in the process of starting and configuring the second lens, generating the first preview image according to the first image data can avoid the situation that the image data cannot be acquired because a certain time is required for starting and configuring the second lens, and the preview image cannot be output in a certain time to cause blocking; after the second lens configuration is completed, a second preview image is generated according to second image data of the second lens and the first image data, wherein the second lens configuration completion means that the second lens can output the second image data, so that after the second lens can output the second image data, a second preview image can be generated according to the second image data and the first image data which are stably output.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
