Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the course of implementing the present application, the applicant finds that, in the prior art, the method for implementing the image preview function of the camera application is as shown in fig. 1: adding image processing functions to the HAL of the camera; and the HAL acquires a preview image, then performs image processing, and outputs the processed image to a display module of the HAL for display. Since the HAL relies on various platforms such as MTK, highpass, spread, etc., the implementation methods of the image preview function of the camera application of different platforms in the prior art are widely different. The scheme in the prior art depends on HAL of each platform, and the code has large realization difference and poor compatibility. In addition, for a three-party mobile phone without source code opening, the HAL source code cannot be obtained, so the scheme in the prior art cannot be implemented.
In view of the above problems, an embodiment of the present application provides an image preview method for camera application, where an image processing function and a display module are added to a frame layer to perform corresponding processing on an image acquired by an HAL, and the image is displayed, so that image preview can be implemented in combination with the frame layer.
The scheme in the embodiment of the application can be realized on a hardware bottom layer of camera application, such as a Framework layer, and can also be realized on an operating system layer.
The scheme in the embodiment of the application can be applied to Camera applications, where the Camera applications may be third-party Camera applications such as Camera360, a universal Camera, a super Camera, and the like, built-in Camera applications of hardware manufacturers such as millet, samsung, association, kupai, huashi, and the like, and Camera applications carried by third-party Operating systems such as an Operating System (Operating System) and the like, a millet ROM (Android third-party Operating System), a hundreds ROM, and the like.
Example one
Fig. 2 is a flowchart of an image preview method for a camera application according to an embodiment of the present application.
As shown in fig. 2, an image preview method for a camera application according to an embodiment of the present application includes the following steps:
s201, triggering a Framework to receive an image collected by a hardware adaptation layer HAL;
s202, processing the image to obtain a processed image;
s203, outputting the processed image to a display module corresponding to the Framework layer, namely, surface texture, and displaying the processed image.
In a specific embodiment of S201, the Framework may be triggered to receive the image collected by the HAL by an image backhaul component of the HAL (the function is a standard function, and all platforms support).
In a specific embodiment of S202, a plurality of image processing methods commonly used by those skilled in the art may be adopted to perform a plurality of modes of processing on the image, such as beauty, nostalgic, wash, black and white, candle light, etc., which is not limited in this application.
In a specific implementation, the Framework may be an operating system self-contained Framework such as Android system, and the Framework may be used to apply APK to the camera to control an interface of camera hardware.
In specific implementation, the interface between the image preview method of the camera application and the Framework in the embodiment of the present application may adopt various logics and names, and it should be understood by those skilled in the art that the interface only needs to be capable of displaying an image on the display module.
In specific implementation, the image preview method of the camera application in the embodiment of the present application may be implemented in a source code form, and may also be called by a Framework in a static library or a dynamic library form.
In particular implementations, the display module may be a software function module for display, created by a camera application.
In this embodiment of the application, before step 203, a display module may also be set for Framework in advance, where the display module may be surface texture in the android system.
In specific implementation, a display module can be set for the Framework layer by setting the display module of the HAL as the display module of the Framework; more specifically, the handle user of the display module of the HAL may be modified to a Framework; for example, in the android system, the handle user of the SurfaceTexture is changed from the original HAL to the Framework. This single display module approach also works with this solution on certain platforms, i.e., while the display logic of the HAL is modified (i.e., the HAL is no longer displaying), it is also operable on platforms such as MTK, highpass, samsung Exynos.
In specific implementation, a display module may be set for the Framework layer in a manner of creating a new display module and setting the created display module as the display module of the Framework. In particular implementation, a new SurfaceTexture may be created by invoking a UI (User Interface) Interface at the application layer of the android system. By adopting a double-display module mode of adding a display module to the Framework, the display logic of the HAL can be prevented from being modified, and the cross-platform mode can be better realized.
In another specific implementation manner of the embodiment of the present application, before triggering the Framework to receive the image acquired by the hardware adaptation layer HAL, the method may further include: an image preview mode of a camera application is acquired, the image preview mode including a processing mode and a non-processing mode.
In this embodiment, the image preview mode of the camera application may be set by the user, or may be set by default by the camera application, which is not limited in this application. In a specific implementation, the processing mode may require the camera to provide a processed image for the user to preview, and the non-processing mode may require the camera to provide an image acquired by the original HAL layer for the user to preview. Through the setting of the image preview mode, more preview modes can be provided for the user, and the user experience is improved.
In another specific implementation manner of the embodiment of the present application, when a dual display module manner is adopted in which a display module is newly added to a Framework, in order to avoid an influence between a display module of the HAL and the Framework display module, the display module of the HAL may be hidden when an image preview mode is a processing mode; and meanwhile, outputting the processed image to a display module of the Framework for displaying.
In particular implementation, hiding the display module of the HAL may be achieved by setting parameters of the display module of the HAL, for example, setting the transparency of the display module of the HAL to 100%, or, alternatively, setting the size of the display module of the HAL to be very small, for example, 1 × 1 pixels; it is also possible to place the display module of the HAL outside the user's field of view in the display screen, e.g. by placing the display module of the HAL in a fixed position outside the field of view, e.g. at the top right corner of the field of view (0, -9999) from the top of the page.
In specific implementation, the display module of the HAL may be hidden by setting parameters of the display module of the Framework, for example, the position of the display module of the Framework is set above the display module of the HAL, and the transparency of the display module of the Framework is set to 0%. Since the code of the display module of the HAL is not modified and the operating logic of the HAL is not modified, i.e. not affected by setting certain parameters; therefore, does not rely on HAL, so cross-platform capability is greatly enhanced.
In another specific implementation manner of the embodiment of the present application, when a dual display module manner is adopted in which a display module is newly added to a Framework, in order to avoid an influence between a display module of a HAL and the Framework display module, the display module of the Framework may be hidden when an image preview mode is a non-processing mode; and outputting the image collected by the HAL to a display module of the HAL for displaying.
In specific implementation, the display module of the Framework may be hidden in various ways, for example, the transparency of the display module of the Framework is set to 100%, or the position of the display module of the HAL is set above the display module of the Framework, and the transparency of the display module of the HAL is set to 0%; it is also possible to set the size of the display module of the Framework to be very small, for example 1 × 1 pixels; it is also possible to place the display module of the Framework outside the user's visible area in the display screen, for example, to place the display module of the Framework at a fixed position outside the visible area, for example, at the top right corner of the visible area (0, -9999) of the page.
In a specific implementation manner of the embodiment of the present application, when the image acquired by the HAL includes a human face; the processed image can be a beautified image; processing the image may specifically include: identifying a human face in an image acquired by HAL; and (5) performing beautifying treatment on the face.
By adopting the image preview method applied to the camera in the embodiment of the application, the image preview can be realized by combining the Framework layer, and because the Framework is a self-contained frame of the system and does not depend on a platform, the Framework can be used across platforms and mobile phones, and the compatibility is improved.
In addition, compared with the image preview realized on the camera application APK layer in the related art, the transmission of the preview image to the APK requires one cross-process transmission and at least one JNI (JAVA native interface, JAVA native call) copy, which consumes a long time and affects the user experience.
By adopting the image preview method applied to the camera in the embodiment of the application, the Framework layer is combined without cross-process transmission and JNI copying of the image to be previewed, the fluency is better than that of APK realization, the time consumption is shorter, and the user experience is improved.
The following describes a flow of an image preview method in the embodiment of the present application, taking a specific application example as an example.
Example two
Fig. 3 is a flowchart of an image preview method of a camera application according to a second embodiment of the present application.
In the second embodiment of the present application, a mode of setting the display module of the HAL as a single display module of the Framework is adopted.
As shown in fig. 3, the image preview method of the camera application according to the second embodiment of the present application includes the following steps:
s301, receiving an image preview mode selected by a user;
s302, outputting the image to a Framework layer after the HAL collects the image;
s303, if the image preview mode selected by the user is a non-processing mode, executing the steps S304-S305; if the mode is 'beauty' processing mode, executing steps S306-S307;
s304, performing transparent transmission processing on the image in the Framework layer, namely, directly outputting the input image without processing the image;
and S305, outputting the image subjected to the transparent transmission processing to a display module of a Framework layer for displaying. At this point, the image preview in the non-processing mode ends.
After performing step S305, the user sees an unprocessed image displayed by the display module of the Framework layer.
S306, combining the Framework layer to perform beautifying processing on the image;
and S307, outputting the image after the beautifying processing to a display module of a Framework layer for displaying. At this point, the image preview in the processing mode ends. After performing step S307, the user sees the beautified image displayed in the display module of the Framework layer.
EXAMPLE III
Fig. 4 is a flowchart of an image preview method for a camera application according to a third embodiment of the present application.
In the third embodiment of the present application, a dual display module manner is adopted in which a new display module is created for the Framework.
As shown in fig. 4, the image preview method of the camera application according to the third embodiment of the present application includes the following steps:
s401, receiving an image preview mode selected by a user;
s402, outputting the image to a display module and a Framework layer of the HAL after the HAL collects the image;
s403, if the image preview mode selected by the user is a non-processing mode, executing steps S404 and S405; if the mode is the 'beauty' processing mode, steps S406 and S407 are executed;
s404, carrying out transparent transmission processing on the image in the Framework layer, namely, directly outputting the input image without processing the image, and outputting the image after transparent transmission to a display module of the Framework layer;
s405, triggering a display module of the hidden Framework. At this point, the image preview in the non-processing mode ends.
After performing step S405, the user sees an unprocessed image displayed in the display module of the HAL.
In specific implementation, the time sequence between steps S404 and S405 is not strict, and S404 may be executed first, and then S405 may be executed; s405 may be executed first, and then S404 may be executed.
S406, combining the Framework layer to perform beautifying processing on the image, and outputting the image after beautifying to a display module of the Framework layer;
s407, triggering the display module of the hidden HAL. At this point, the image preview in the processing mode ends.
After performing step S407, the user sees a beautified image displayed in the display module of the Framework layer.
In specific implementation, the steps S406 and S407 do not have a strict time sequence, and S406 may be executed first, and then S407 may be executed; s406 may be executed first, and then S407 may be executed.
Because the display module, such as the surfaceTexdue in the android system, is a standard component provided by the operating system, the creation, hiding, displaying, and the like of the display module do not depend on a platform, so that the cross-platform capability of the embodiment of the application is improved.
By adopting the image preview method applied to the camera in the embodiment of the application, the image preview can be realized by combining the Framework layer, and because the Framework is a self-contained frame of the system and does not depend on a platform, the Framework can be used across platforms and mobile phones, and the compatibility is improved.
