In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.
The application layer may include a series of application packages.
As shown in fig. 2, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.
The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.
As shown in FIG. 2, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.
The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.
The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.
The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views.

The resource manager provides various resources, such as localized strings, icons, pictures, layout files, video files, etc., to the application.
The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, a prompt tone is given, the terminal vibrates, an indicator light flashes, and the like.
The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.
The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.
The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.
The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.
The following describes exemplary workflow of the terminal 100 software and hardware in connection with capturing a photo scene.
When the touch screen 131 receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 140.

Fig. 4 is a schematic diagram of an image display method according to an embodiment of the present invention, as shown in fig. 4, specifically including the following steps:
step 400: when a camera opening instruction is received, the current standard color temperature of the display screen is adjusted to be the shooting color temperature, so that the display screen displays images based on the shooting color temperature in shooting application.
In this embodiment, in order to make the display effect of the display screen close to the shooting effect and not affect the display effect of the display screen in other applications, only the standard color temperature of the display screen needs to be adjusted in the shooting process, and the display screen is not needed to display images with the shooting color temperature before shooting. Based on this, when a camera opening instruction is received, the shooting process is determined to be started, and the current standard color temperature of the display screen is adjusted to the shooting color temperature, so that the display screen displays images based on the shooting color temperature in the shooting application.
In this embodiment, the manner of receiving the camera opening instruction is not limited, for example, a user touches a "camera" application icon on a user interface of the terminal to trigger the camera opening instruction, and the processor of the terminal receives the camera opening instruction.
It will be appreciated that the standard color temperature described above may be a default color temperature for the display screen.
For example, the shooting color temperature may be a color temperature value, and may be a color temperature range. When the shooting color temperature is a color temperature value, the color temperature of the display screen can be adjusted to the value; when the shooting color temperature is in a color temperature range, the color temperature of the display screen is adjusted to the color temperature range, and the adjustment is more flexible and convenient because the adjustable value of the color temperature is in a range.
Optionally, the standard color temperature includes a standard R/G/B component, the photographing color temperature includes a photographing R/G/B component,
the adjusting of the current standard color temperature of the display screen to the shooting color temperature includes:
and adjusting the standard R/G/B component into the shooting R/G/B component based on a 3Gamma algorithm.
Illustratively, the standard R/G/B component is input into a color adjusting module of the post-processing unit, and the color adjusting module outputs a target R/G/B component through a 3Gamma algorithm, so that the current standard color temperature of the display screen is adjusted to the shooting color temperature.
Step 401: and when a camera closing instruction is received, adjusting the shooting color temperature of the display screen to the standard color temperature so that the display screen displays images based on the standard color temperature in other applications.
As described above, the standard color temperature of the display screen needs to be adjusted only during the shooting process, and therefore, the display screen is not required to be displayed with the shooting color temperature after the shooting is finished. Therefore, when a camera closing instruction is received, the shooting process is determined to be quitted, and the shooting color temperature of the display screen needs to be adjusted back to the standard color temperature, so that the display screen displays images based on the standard color temperature in other applications except shooting.
In this embodiment, the manner of receiving the camera turn-off instruction is not limited, for example, the user triggers the camera turn-off instruction by touching an exit key on the shooting interface, and the processor of the terminal receives the camera turn-off instruction.
According to the scheme, when the camera opening instruction is received, the current standard color temperature of the display screen is adjusted to the shooting color temperature, so that the display screen displays images based on the shooting color temperature in shooting application, and the difference between the display effect of the display screen and the final shooting effect can be reduced; meanwhile, when a camera closing instruction is received, the shooting color temperature of the display screen is adjusted to the standard color temperature, so that the display screen can be displayed based on the original standard color temperature in other applications, and the display effect of the display screen when the other applications are used is not influenced.
In addition, unreasonable selection of the shooting color temperature may cause a large difference between the effect of the image displayed on the display screen and the effect of the final shot image, and in order to improve the rationality of color temperature selection, fig. 5 is another image display method provided by an embodiment of the present invention, as shown in fig. 5, the embodiment specifically includes the following steps based on the embodiment of fig. 4:
step 500: and determining the shooting color temperature according to a preset image.
In this embodiment, in order to make the selection of the shooting color temperature reasonable, different preset images can determine different shooting color temperatures, so that the shooting color temperatures can be changed based on the difference of the preset images.
In a possible implementation manner, when a camera opening instruction is received, an image of a shooting environment is first acquired, and the image can sufficiently reflect a color temperature of the shooting environment, so that the shooting color temperature can be reasonably determined based on the shooting environment, and thus, a difference between a display effect of a display screen and a final shooting effect can be further reduced. The color temperature of different shooting scenes changes greatly, if all the shooting scenes adopt the same shooting rule to shoot images, the preset images can be unreasonably selected, and therefore the target shooting rule corresponding to the shooting scenes can be determined according to the corresponding relation between the preset scenes and the shooting rule, and the camera is controlled to shoot the images according to the determined target shooting rule.
In this embodiment, different shooting scenes correspond to different shooting rules, where the shooting rules may include one or more of a shooting frame number, a shooting time interval of adjacent frames, a shooting duration, and a shooting mode, where the shooting mode includes image shooting and video shooting, a specific shooting rule may be set according to an application scene, and a correspondence between the shooting scene and the shooting rule includes, but is not limited to:
1. when the shooting scene is static shooting of a character with stable light, the shooting rule is image shooting, and the number of the shooting frames is one;
2. when the shooting scene is scene shooting with obvious light change, the shooting rule is image shooting, the number of the shooting frames is 10 frames, and the shooting time interval of adjacent frames is 0.001 s;
3. when the shooting scene is character motion shooting, the shooting rule is video shooting, and the shooting time is 1 s;
4. when the shooting scene is shot by people or scenery with light period change, the shooting rule is video shooting, and the shooting time is a change period; or the shooting rule is image shooting, and the number of the shooting frames and the shooting time interval of the adjacent frames are set according to the light change interval.
The mode of acquiring the shooting scene is not specifically limited in this embodiment, and may be implemented by, but not limited to, the following modes:
through another preset shot image, some target characteristics in the preset shot image are identified, the scene which is shot at present can be determined, user operation is not needed, and the shot scene can be conveniently and quickly determined;
or, the shooting scene is accurately determined by acquiring the shooting scene information sent by the user.
Step 501: when a camera opening instruction is received, the current standard color temperature of the display screen is adjusted to be the shooting color temperature, so that the display screen displays images based on the shooting color temperature in shooting application.
Step 502: and when a camera closing instruction is received, adjusting the shooting color temperature of the display screen to the standard color temperature so that the display screen displays images based on the standard color temperature in other applications.
The steps 501-502 are the same as the steps 400-401, and are not described herein again.
According to the scheme, the shooting color temperature is determined through the preset image, the shooting color temperature can be selected more reasonably, and the display screen can be closer to the final shooting effect when displaying the image based on the shooting color temperature. R/G/BR/G/B
The preset image comprises a plurality of parameters, some parameters are unrelated to the color temperature, and the shooting color temperature can be reasonably determined only based on the parameters capable of reflecting the color temperature in the preset image. In order to improve the reasonableness of the shooting color temperature, fig. 6 is a further image display method provided by an embodiment of the present invention, as shown in fig. 6, the embodiment specifically includes the following steps based on the above embodiment:
step 600: and determining the shooting color temperature according to the white field color coordinate of the preset image.
The white field color coordinates reflect the white balance effect and are the basis for judging whether color cast occurs, so that different white field color coordinates correspond to different color temperatures, for example, when the white field color coordinates are red, the color temperature is high; when the white field color coordinate is blue, the color temperature is low. Based on the white field coordinates of the preset image, the shooting color temperature corresponding to the image can be accurately and reasonably obtained.
For example, the white field color coordinates of the preset image may be determined by, but not limited to, the following methods: and identifying a white field area of the preset image, and determining the color coordinates of the white field area through preset image processing software.
Optionally, based on the white field color coordinate, a shooting color temperature is obtained through a pre-stored correspondence between the white field color coordinate and the color temperature. Through the corresponding relation, the shooting color temperature corresponding to the white field color coordinate can be accurately determined.
For example, if the frame number of the preset image is one frame, the corresponding shooting color temperature can be determined directly according to the white field color coordinates of the frame image.
If the preset image has more than one frame, the target white field color coordinates may be determined by presetting the white field color coordinates of all or part of the image according to the actual application scene, as an example:
1. the target white field color coordinates are determined according to the average value of the white field color coordinates of all the preset images, for example, the number of frames of the preset images is n frames, the white field color coordinates are respectively marked as A1 and A2 … … An, and the target white field color coordinates A is (A1+ A2+ … … + An)/n.
2. According to a preset rule, different images correspond to different weight coefficients and offset, white field color coordinates are corrected according to the offset of all the images, and target white field color coordinates are determined according to a weighted average value of the corrected white field color coordinates, for example, the number of frames of the preset image is n frames, which are respectively marked as A1, A2 … … An, the weight coefficients corresponding to A1 and A2 … … An are respectively marked as B1 and B2 … … Bn, the corresponding offsets are respectively marked as C1 and C2 … … Cn, and the target white field color coordinates A ═ [ (A1+ C1) × B1+ (A2+ C2) × B2+ … … + (An + Cn) ×/n.
The target white field color coordinate can be determined more reasonably by corresponding different images to different weight coefficients and offset, correcting the white field color coordinate according to the offset and comprehensively considering the proportion of each image.
3. When the shooting scene is shot by a character or a scene with light period change, the white field color coordinates of each image in the shot images are determined, and the target white field color coordinates are a series of white field color coordinates.
For a shot of a person or scene with a periodically changing light, the difference between one transformation interval and another transformation interval is large, so that only one white field color coordinate cannot be obtained simply by calculation. By determining a series of white field color coordinates, the color temperature of subsequent shooting can be more consistent with scenes with light period change.
And obtaining the shooting color temperature corresponding to the white field color coordinate or the target white field color coordinate after determining the white field color coordinate or the target white field color coordinate in any mode.
Step 601: when a camera opening instruction is received, the current standard color temperature of the display screen is adjusted to be the shooting color temperature, so that the display screen displays images based on the shooting color temperature in shooting application.
Step 602: and when a camera closing instruction is received, adjusting the shooting color temperature of the display screen to the standard color temperature so that the display screen displays images based on the standard color temperature in other applications.
The implementation of steps 601-602 is the same as that of steps 400-401, and will not be described herein again.
According to the scheme, the shooting color temperature is determined through the white field color coordinate reflecting the white balance effect, and when the white field color coordinate of the preset image is red or blue, different shooting color temperatures can be determined. Therefore, the reasonability of the shooting color temperature can be further improved, and the similarity between the display effect of the display screen and the final shooting effect is improved.
In addition, in order to reduce the difference of the saturation and/or contrast between the image displayed on the display screen and the final captured image, the present embodiment provides another image display method, as shown in fig. 7, which is based on the above embodiment (which is described as an example based on the embodiment of fig. 4), and specifically includes the following steps:

Step 701: and adjusting the current standard saturation and/or standard contrast of the display screen to shooting saturation and/or shooting contrast so that the display screen displays images based on the shooting saturation and/or the shooting contrast in shooting application.
In this embodiment, the order of step 700 and step 701 is not limited, that is, step 700 may be executed first, step 701 may be executed first, or step 700 and step 701 may be executed simultaneously.
Step 702: and when a camera closing instruction is received, adjusting the shooting color temperature of the display screen to the standard color temperature so that the display screen displays images based on the standard color temperature in other applications.
Step 703: adjusting the shooting saturation and/or the shooting contrast of the display screen to the standard saturation and/or the standard contrast so that the display screen displays images based on the standard saturation and/or the standard contrast in other applications.
In this embodiment, the order of step 702 and step 703 is not limited, that is, step 702 may be executed first, step 703 may be executed first, or step 702 and step 703 may be executed simultaneously.
In addition, in order to improve flexibility and real-time performance of color temperature adjustment, the color temperature of the shooting environment can be acquired in real time in the shooting process, and the shooting color temperature of the display screen of the terminal is adjusted in real time according to the color temperature of the shooting environment. The embodiment does not limit the specific manner of acquiring the color temperature of the shooting environment in real time, and for example, the color temperature may be acquired by a color temperature sensor.
