Description

Picture mode switching method and electronic equipment

Technical Field

The present application relates to the field of terminals and video technologies, and in particular, to a method for switching a graphic mode and an electronic device.

Background

In the process of recording video, the shooting scene of the electronic device can be one or more of a high dynamic scene or a low dynamic scene (non-high dynamic scene). Reasons for the occurrence of highly dynamic scenes include: the light of the shooting scene may not always be normal light, and usually bright light or dark light may occur, and a situation that part of the shooting area is bright light and part of the shooting area is dark light may occur, for example, when a portrait is shot by backlight, a situation that a portrait area is dark light and other areas are bright light may occur. When the shooting area is provided with a dark light area and a bright light area, and the contrast of the brightness of the shooting area is strong, the shooting scene is a high dynamic scene. Correspondingly, the reasons for the occurrence of the low dynamic scene include: when the contrast of the brightness of the shooting area is small or no contrast of the brightness exists, the shooting scene is a non-high dynamic scene, for example, a low dynamic scene.

The electronic equipment can record video in a high-dynamic video mode in a high-dynamic scene, when the high-dynamic video mode is started, the picture mode of the electronic equipment is different from the picture mode when the high-dynamic video mode is closed, and in the video recording process, how to determine the picture mode of the electronic equipment is worth discussing.

In the above embodiment, after the electronic device starts recording the video, the image capturing manner may be determined based on whether the shooting environment is a highly dynamic scene. In this way, the quality of the recorded video can be improved.

With reference to the first aspect, in some embodiments, the electronic device displays a high dynamic indicator of the first state, specifically including: the electronic equipment determines that a shooting scene corresponding to first time is a high-dynamic scene based on exposure parameters corresponding to the first time; the first time is a time before the electronic device displays the high dynamic indicator icon of the first state.

Detailed Description

The terminology used in the following embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates to the contrary. It should also be understood that the term "and/or" as used in this disclosure refers to and encompasses any or all possible combinations of one or more of the listed items.

The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In one approach, the electronic device sets a separate recording mode for the high dynamic scene, which may be referred to as high dynamic recording. When the user determines that the shooting scene is a high dynamic scene, the electronic equipment can enter a high dynamic video recording mode to shoot the video.

Fig. 1 shows a schematic diagram of an electronic device entering a high dynamic video recording mode.

As shown in fig. 1 (1), the user interface 11 is an exemplary desktop of the electronic device. The user interface 11 has a camera application icon 111 displayed therein. The electronic device may detect an operation (e.g., a click operation) by the user on the camera application icon 111, in response to which the electronic device activates the camera and may display the user interface 12 as shown in fig. 1 (2).

As shown in fig. 1 (2), the user interface 12 is one exemplary user interface for the electronic device when shooting. At this time, the electronic device enters a video recording mode, and can record video. When the user determines that the shooting scene is a high dynamic scene, the electronic equipment can enter a high dynamic video recording mode to shoot the video. An exemplary description of one of the entry into the high dynamic video recording mode may be referred to below.

In response to the operation for the more controls 121a, the electronic device may display more shooting modes, including the high dynamic video recording mode. For example, referring to the user interface 13 shown in (3) of fig. 1, the user interface 13 may be an exemplary user interface displayed after responding to the operation for the more controls 121 a. In response to an operation (e.g., a click operation) for the high dynamic video control 131, the electronic device may switch the shooting mode to the high dynamic video mode. Subsequently, in response to an operation (e.g., a click operation) for start video control 132, the electronic device may capture video in a high dynamic video mode. User interface 14, shown in fig. 1 (4), is one exemplary user interface that may be involved in capturing video in a high dynamic video mode of an electronic device.

Subsequently, the electronic device may record video in a high dynamic video recording mode. But in the whole video recording process, the high dynamic video recording mode is adopted. The picture mode can not be switched to other picture modes in the preview process and the video recording process, and the picture modes are all picture modes in the high-dynamic video recording mode. Even for non-highly dynamic scenes that occur during the preview process and during the video recording process, it is not possible to switch to other modes of graphics.

And whether the shooting environment is a high dynamic scene is judged by a user, and the judgment of the high dynamic scene has certain difficulty for the user. A situation may occur in which the judgment is erroneous, that is, the process of judging whether the shooting environment is a highly dynamic scene is not intelligent enough.

It should be understood herein that the preview process includes a scene in which the electronic device begins displaying the captured image but does not begin recording video. The video recording process includes affecting the operation of a start video control (e.g., start video control 132) that the electronic device begins displaying based on the acquired image and deriving a scene of the video based on the acquired image.

In another possible manner, during the preview process, the electronic device may identify whether the current shooting scene is a high dynamic scene, and if so, may display a high dynamic indication icon to prompt the user that the current scene is a high dynamic scene. In this manner, the high dynamic indication icon corresponds to a shortcut portal, and in response to the operation for the high dynamic indication icon, the electronic device may record video in the high dynamic recording mode.

Fig. 2A and 2B show another schematic diagram of the electronic device entering the high dynamic video recording mode.

As shown in (1) in fig. 2A, referring to the user interface 11, in response to an operation (e.g., a click operation) for the camera application icon 111, the electronic device starts the camera and may display the user interface 21 as shown in (2) in fig. 2A.

The user interface 21 is an exemplary user interface that is involved in entering a video recording mode of the electronic device. After entering the video mode, the electronic device may turn on the scene detection function. For example, referring to the user interface 21, the smart detection indicator 211 may be displayed in the user interface 21, and in the case where the scene detection function is on, the state of the smart detection indicator 211 is state a, for example, the state in the user interface 21 may be state a. When the scene detection function is turned off, the state of the smart detection indicator 211 is a state B, which is different from the state a described above.

Under the condition that the scene detection function is started, the electronic equipment can identify whether the current shooting scene is a high-dynamic scene or not, and if the current shooting scene is the high-dynamic scene, a high-dynamic indication icon can be displayed to prompt a user that the current scene is the high-dynamic scene. At this time, one exemplary user interface for the electronic device to display the high dynamic indication icon may refer to the user interface 22 shown in (3) of fig. 2A described below.

As shown in fig. 2A (3), the user interface 22 is an exemplary user interface involved in displaying a high dynamic indication icon in the case where the electronic device determines that the current shooting scene is a high dynamic scene. The high dynamic indication icon may be an indication icon 221 shown in the user interface 22. After entering the video mode each time, the electronic device may further display a prompt corresponding to the high dynamic indication icon within a preset time a after the high dynamic indication icon (for example, indication icon 221) is displayed for the first time in the preview process, for example, the prompt may be displayed around the high dynamic indication icon. The prompt information is used for prompting that the current shooting scene is a high dynamic scene, and a user can start the high dynamic video through the electronic equipment. The preset time a may be a duration of 1s-5s, for example, 2s, or may be other times, which is not limited in the embodiment of the present application. As shown in the user interface 22, the prompt may be text 222: "high dynamic video recording".

In the preview process, the time counting starts after the high dynamic indication icon (for example, indication icon 221) is displayed for the first time, and after the preset time a is reached, the electronic device does not display the prompt information corresponding to the high dynamic indication icon any more. Such as user interface 23 shown in fig. 2A (4), which is a user interface involved when the preset time a is exceeded after the high dynamic indication icon is displayed. At this point, the indication icon 221 may still be included in the user interface 23.

In response to operation of the indicator icon 221, the electronic device may enter a high dynamic video recording mode to begin recording video. One exemplary user interface referred to at this time may be referred to as user interface 24 shown in FIG. 2B, described below.

In this way, in the preview process, the electronic device can intelligently judge whether the current shooting scene is a high-dynamic scene or not, and provide a shortcut entry of a high-dynamic video recording mode.

However, in this manner, in the preview mode and in the high dynamic scenario, the user cannot switch the drawing mode of the electronic device to another drawing mode through the electronic device, and the switching of the drawing mode is still not flexible enough.

The embodiment of the application provides a graph mode switching method. In the method, the electronic equipment can intelligently judge whether the current shooting scene is a high-dynamic scene in the preview process, and if the current shooting scene is the high-dynamic scene, a high-dynamic indication icon can be displayed to prompt a user that the current scene is the high-dynamic scene. And the user can set whether to start the high dynamic video recording mode or not through the high dynamic indication icon. After the high-dynamic video recording mode is started and video recording starts, the electronic device may also determine a mapping mode based on whether the photographed scene is a high-dynamic scene again, map the high-dynamic scene using an optimal two-way conversion gain (ideal dual conversion gain, iDCG) mode, and map the non-high-dynamic scene using a pixel merging (binning) mode.

The binding mode and the iDCG mode indicate the way the camera outputs an image. Reference may be made in particular to the following description.

When the photographed scene is a non-high dynamic scene, the electronic device may acquire an image using a binning (binning) mode and obtain a video based on the acquired image. The binding mode is to add charges induced by adjacent pixels of an original image together and read out the image in a one-pixel mode. That is, the camera adds the charges induced by adjacent pixels of the original image together, reads out the charges in a one-pixel mode, and outputs the image.

When the shooting scene is a high dynamic scene, the electronic device can use high dynamic range (highdynamic range, HDR) processing to enable the image acquired by the electronic device to be a high dynamic range image, so that the image quality is higher, and the shooting object can be reflected more truly. During the HDR process, the electronic device may acquire an image (map) using an optimal two-way conversion gain (ideal dual conversion gain, iDCG) mode. The process of obtaining the high dynamic range image by the electronic device in the iDCG mode comprises the following steps: compared with the binding mode, the electronic device additionally turns on a two-way conversion gain (dual conversion gain, DCG) electronic device in the camera sensor, the original image acquired by the camera sensor is divided into a low conversion gain (Low conversion gain, LCG) image and a high conversion gain (high conversion gain, HCG) image by the DCG electronic device to be processed, and finally, the images are fused to obtain a frame of image with high dynamic range. That is, the camera divides the original image into a low conversion gain (Low conversion gain, LCG) image and a high conversion gain (high conversion gain, HCG) image, processes the images, and finally fuses the images to obtain a frame of image with a high dynamic range, and then outputs the image with the high dynamic range.

The LCG image may be adjusted to the bright areas such that the bright areas are not overexposed. The HCG image may adjust the dark regions so that the dark regions are clear.

Fig. 3A-3C illustrate an exemplary set of user interfaces for an electronic device to switch a graphical mode in an embodiment of the application.

As shown in (1) in fig. 3A, referring to the user interface 11, in response to an operation (e.g., a click operation) for the camera application icon 111, the electronic device starts the camera and may display the user interface 31 as shown in (2) in fig. 3A.

The user interface 31 is another exemplary user interface that is involved in entering a video recording mode of the electronic device. After entering the video mode, the electronic device may turn on the scene detection function. For example, referring to the user interface 31, the smart detection indicator 211 may be displayed in the user interface 31. The description of the smart detection indicator 211 may be referred to the foregoing and will not be repeated here.

Under the condition that the scene detection function is started, the electronic equipment can identify whether the current shooting scene is a high-dynamic scene or not, and if the current shooting scene is the high-dynamic scene, a high-dynamic indication icon can be displayed to prompt a user that the current scene is the high-dynamic scene. At this time, one exemplary user interface for the electronic device to display the high dynamic indication icon may refer to the user interface 32 shown in (3) of fig. 3A described below.

As shown in (3) of fig. 3A, the user interface 22 is an exemplary user interface involved in displaying a high dynamic indication icon in the case where the electronic device determines that the current shooting scene is a high dynamic scene. The high dynamic indication icon may be an indication icon 321 shown in the user interface 22. After each video recording mode is entered, the electronic device may further display a prompt corresponding to the high dynamic indication icon within a preset time a after the high dynamic indication icon (for example, indication icon 221) is displayed for the first time in the preview process, for example, the prompt may be prompt 322: "high dynamic video recording". The related description related to the preset room a and the display mode of the prompt message may refer to the related description related to (3) in fig. 2A, which is not repeated herein.

In some possible cases, the electronic device may start timing after displaying the high dynamic indication icon (for example, indication icon 221) for the first time in the preview process, and after reaching the preset time a, the electronic device may no longer display the prompt information corresponding to the high dynamic indication icon. For example, referring to the user interface 33 shown in (4) of fig. 3A, the user interface is referred to when the preset time a is exceeded after the high dynamic indication icon is displayed. At this time, the indication icon 321 may still be included in the user interface 33, but the prompt information 322 corresponding to the indication icon 321 is not displayed.

In some possible cases, the condition that the electronic device displays the high dynamic indication icon after determining that the shooting scene is the high dynamic scene may further include: the corresponding focal length is larger than or equal to the preset focal length when video is recorded. The preset focal length may be a focal length corresponding to a 1x zoom magnification, or may be other values, for example, a focal length corresponding to a 1.5x zoom magnification, which is not limited in the embodiment of the present application.

The electronic equipment can set the corresponding zoom magnification when recording video through the zoom magnification control, so that the focal length is changed. Here, a preset focal length is described as an example of a focal length corresponding to a 1x zoom magnification. Reference is made to the user interface 33 shown in fig. 3A (4). As shown in user interface 33, one exemplary illustration of a zoom magnification control may be zoom magnification control 331. The zoom magnification control 331 may be configured to receive an instruction to change the zoom magnification and prompt the user of what the current zoom magnification is. The zoom magnification control 331 may further include indicators corresponding to different zoom magnifications, where the indicators corresponding to the different zoom magnifications are used to indicate different zoom magnifications.

In response to the indicator 331a corresponding to the 0.5x zoom magnification in the zoom magnification control 331, the electronic device may set the zoom magnification to 0.5x. At this time, the focal length of the electronic device is a focal length corresponding to a 0.5x zoom magnification and is smaller than a focal length corresponding to a 1x zoom magnification. The electronic device no longer displays a high dynamic indication icon (e.g., indication icon 321). An exemplary user interface that is referred to when the indication icon 321 is not displayed may refer to the user interface 34 shown in (1) of fig. 3B.

Referring to the user interface 34 shown in (1) in fig. 3B, in response to the indicator 331B corresponding to the 2x zoom magnification in the zoom magnification control 331, the electronic device may set the zoom magnification to 2x. At this time, the focal length of the electronic device is a focal length corresponding to 2x zoom magnification and is greater than a focal length corresponding to 1x zoom magnification. After the electronic device determines that the shooting scene is a high dynamic scene, a high dynamic indication icon (e.g., indication icon 321) may be displayed. At this time, one exemplary user interface to which the electronic device relates may refer to the user interface 35 shown in (2) of fig. 3B.

In some possible cases, after the electronic device determines that the shooting scene is a high dynamic scene, in the case of displaying a high dynamic indication image, the user may also set whether to turn on the high dynamic video recording mode through the high dynamic indication icon. One possible implementation includes: after entering the video mode each time, the state of displaying the high dynamic indication icon for the first time in the preview process is recorded as a state 1, and the high dynamic indication icon in the state 1 can prompt the user that the current scene is the high dynamic scene. The electronic device may also be instructed to turn on the high dynamic video recording mode. The high dynamic indication icon in this state 1 may also be used to set the off high dynamic video recording mode. When the high dynamic video mode is turned off, the state of the high dynamic indication icon can be switched from the state 1 to the state 2. Correspondingly, the high dynamic indication icon in the state 2 not only can prompt the user that the current scene is a high dynamic scene. The electronic device may also be instructed to turn off the high dynamic video recording mode. The high dynamic indication icon in this state 2 can also be used to set the high dynamic recording mode on. When the high dynamic video recording mode is started, the state of the high dynamic indication icon can be switched from the state 2 to the state 1.

Referring to fig. 3B, (2), the indication icon 321 displayed in the user interface 35 is a high dynamic indication icon in an exemplary state 1. In response to an operation (e.g., a click operation) for the indication icon 321 in this state 1, the electronic device may change the display state of the indication icon 321 to change it to the indication icon 321 in state 2. At this time, the electronic device may display the user interface 36 shown in (1) in fig. 3C.

Referring to the user interface 36 shown in fig. 3C (1), the electronic device may change the color of the indication icon 321 to indicate that the current electronic device has turned off the high dynamic video recording mode. For example, from gray as shown in user interface 35 to white as shown in user interface 36.

It should be understood that, in the foregoing, the state 1 is color 1 (e.g. gray), and the state 2 is color 2 (e.g. white), which is taken as an example, and in practical situations, the state 1 is different from the state 2, which is not limited in the embodiment of the present application. For example, the shape of the state 1 may be different from the shape of the state 2.

When the high dynamic indicator is in the state 2, the electronic device is indicated to close the high dynamic video recording mode in the preview process, and the drawing mode of the electronic device can be set to be a binding mode. In response to an operation (e.g., a click operation) for a start video control (e.g., start video control 132), the electronic device may set a mapping mode corresponding to the first N frames of images to a binding mode during the start of video recording. At this time, one exemplary user interface that the electronic device may display is user interface 37a shown in fig. 3C (2). Where N is a positive integer greater than or equal to 1, for example N is equal to 1.

In the process of starting to record video, the electronic device uses the image mode corresponding to the subsequent image (the image after the nth frame) to include, but is not limited to, the following cases:

case 11: the graph modes corresponding to the subsequent images can be set to a binding mode. One implementation of this case 11 includes: during video recording, the picture mode (binding mode) used during the preview is kept unchanged.

Case 12: the pattern of the subsequent image may be set by the electronic device according to whether the current shooting scene (e.g., time 11) is a high dynamic scene. If the shooting scene is a high dynamic scene at time 11, the image pattern corresponding to the image acquired at time 11 is an iDCG pattern. If the shooting scene is a non-high dynamic scene at time 11, the image pattern corresponding to the image acquired at time 11 is a binding pattern. The time 11 may be a time or a time period.

In case 11 and case 12, the user interface displayed by the electronic device during the video recording process may refer to the user interface 37a shown in (2) of fig. 3C described above.

Case 13: the graph mode corresponding to the subsequent image may be determined by the electronic device according to whether the current shooting scene (e.g., time 11) is a high dynamic scene, in combination with the user setting. If the shooting scene is a high dynamic scene at time 11 and the user sets to start the high dynamic video recording mode, the image corresponding to the image acquired at time 11 is in the iDCG mode. If the shooting scene is a non-high dynamic scene at time 11, or if the shooting scene is a high dynamic scene but the user sets to close the high dynamic video recording mode, the image corresponding to the image acquired at time 11 is a binding mode.

This case 13 can be referred to the description of (1) in fig. 3C and (3) in fig. 3C. As shown in fig. 3C (1), in response to operation of start video control 132, the electronic device starts recording video. After starting recording the video, one exemplary user interface displayed by the electronic device may be user interface 37b shown in fig. 3C (3). The user interface 37b may include a video mode indication icon (e.g., indication icon 371). The recording mode indication icon 371 may be used to indicate whether the high dynamic recording mode is turned on.

The state of the indication icon 371 is state 3 when the first N frames of images of the video are recorded. The state 3 indicates that the icon 371 is used to indicate that the high dynamic recording mode is not on (off). Subsequently, the electronic device changes the state of the indication icon 371 according to whether the current shooting scene is a high dynamic scene or not, or according to whether the current shooting scene is a high dynamic scene or not and the user setting. For example, when the current shooting scene is a high dynamic scene and the high dynamic video mode is turned on, the electronic device changes the state of the indication icon 371 to a state 4 to indicate that the high dynamic video mode is turned on, and the state 4 is different from the state 3. An exemplary description about this state 4 may refer to the indication icon 371 shown in (3) in fig. 4 below. And will not be described in detail herein. For another example, in the case where the current photographing scene is a high dynamic scene, the indication icon 371 of the state 4 is displayed by default to indicate that the high dynamic video recording mode is turned on. In response to a user operation of the indication icon 371 for state 4, the electronic device may change the state of the indication icon 371 from state 4 to state 3 to indicate that the high dynamic video recording mode is turned off. Subsequently, in the case that the shooting scene is a high dynamic scene, the user can start the high dynamic video recording mode through the indication icon 371.

Fig. 3C illustrates the related content related to the electronic device starting to record video in response to the operation of the start recording control when the high dynamic recording mode is turned off in the preview process.

FIG. 4 illustrates a set of user interfaces involved in an electronic device beginning to record video when a high dynamic video recording mode is turned on during a preview process.

In response to an operation for starting the video recording control in the case of starting the high dynamic video recording mode in the preview process, the following description of fig. 4 may be referred to for related content related to starting video recording by the electronic device.

When the high dynamic indicator is in a state 1, the electronic equipment is indicated to start a high dynamic video recording mode in the preview process, and the picture mode of the electronic equipment can be set to be an iDCG mode. As shown in fig. 4 (1), in the user interface 41, in response to an operation (e.g., a clicking operation) for a start video control (e.g., a start video control 132), the electronic device may set an icon corresponding to the previous N frames of images in the process of starting video recording to be in the iDCG mode. At this point, one exemplary user interface that the electronic device may display is user interface 42a shown in fig. 4 (2). Where N is a positive integer greater than or equal to 1, for example N is equal to 1.

The electronic device starts the process of recording video, and the image pattern corresponding to the subsequent image (the image after the nth frame) includes, but is not limited to, the following cases:

case 21: the graph modes corresponding to the subsequent images may be all set to the iDCG mode. One implementation of this case 21 includes: during video recording, the graphic mode (iDCG mode) used during the preview is kept unchanged.

Case 22: the pattern of the subsequent image may be set by the electronic device according to whether the current shooting scene (e.g., time 21) is a high dynamic scene. If the photographing scene is a high dynamic scene at time 21, the image pattern corresponding to the image acquired at time 21 is an iDCG pattern. If the shooting scene is a non-high dynamic scene at time 21, the image pattern corresponding to the image acquired at time 21 is a binding pattern. The time 21 may be time or a time period.

In case 21 and case 22, the user interface displayed by the electronic device during the video recording process may refer to the user interface 42a shown in (2) of fig. 4.

Case 23: the pattern of the subsequent image may be determined by the electronic device in connection with the user setting according to whether the current shooting scene (e.g., time 21) is a high dynamic scene. If the shooting scene is a high dynamic scene at time 21 and the user sets to start the high dynamic video recording mode, the image corresponding to the image acquired at time 21 is in the iDCG mode. If the shooting scene is a non-high dynamic scene at the time 21, or if the shooting scene is a high dynamic scene but the user sets to close the high dynamic video recording mode, the image corresponding to the image acquired at the time 21 is a binding mode.

This case 13 can be referred to the description of (1) in fig. 4 and (3) in fig. 4. As shown in fig. 4 (1), in response to operation of start video control 132, the electronic device starts recording video. One exemplary user interface displayed by the electronic device after the video recording has begun may be user interface 42b shown in fig. 4 (3). The user interface 42b may include a video mode indication icon (e.g., indication icon 371). The recording mode indication icon 371 may be used to indicate whether the high dynamic recording mode is turned on.

The state of the indication icon 371 is state 4 when the first N frames of images of the video are recorded. The state 4 indicates that the icon 371 is used to indicate that the high dynamic recording mode is on. Subsequently, the electronic device changes the state of the indication icon 371 according to whether the current shooting scene is a high dynamic scene or not, or according to whether the current shooting scene is a high dynamic scene or not and the user setting. The description of this process may refer to the foregoing related content, and will not be repeated here.

It should be understood that, when the electronic device displays the high dynamic indication icon and further displays the prompt information corresponding to the high dynamic indication icon, the electronic device may still receive the operation of the user on the high dynamic indication icon to set whether to start the high dynamic video recording mode.

FIG. 5 illustrates an exemplary set of user interfaces for setting whether to turn on a high dynamic video recording mode based on a high dynamic indication icon.

As in the user interface 51 shown in fig. 5 (1), when a high dynamic indication icon (e.g., indication icon 321) is displayed, a corresponding prompt, such as prompt 322, is also displayed. At this time, the state of the high dynamic indication icon (e.g., indication icon 321) is state 1 (e.g., gray), which indicates that the electronic device has turned on the high dynamic video recording mode, and the drawing mode at this time is the IDCG mode. In response to an operation (e.g., a clicking operation) of the indication icon 321 for the state 1, the electronic device may change the state of the indication icon 321 to a state 2 (e.g., white in color), which indicates that the electronic device has turned off the high dynamic video recording mode, and the drawing mode at this time is a binding mode. An exemplary user interface displayed by the electronic device at this point may be referred to as user interface 52 shown in fig. 5 (2).

It should be appreciated here that using the iDCG mode diagram may result in an increase in power consumption of the electronic device compared to the binding mode. The reason for the increase in power consumption is that: the iDCG mode turns on one DCG electronic device more than the binning mode, and the process of obtaining an image based on an original image is more complicated, thus increasing power consumption. For the relevant description of the two modes, reference is made to the foregoing background art, and details are not repeated here.

In the recording process and the previewing process, the picture can be switched to the binding mode when the shooting scene is a non-high dynamic scene, and compared with the picture in the binding mode after entering the high dynamic video recording mode, the picture in the non-high dynamic scene can not be switched to the binding mode (such as the schemes of fig. 1, 2A and 2B) in time, so that the power consumption can be saved.

Based on the above, according to the method according to the embodiment of the present application, the electronic device may intelligently determine whether the current shooting scene is a high dynamic scene in the preview process, provide a shortcut entry for the high dynamic video recording mode, and enable the high dynamic video recording mode through the electronic device. In addition, in the video recording process, the electronic equipment can also determine the graph mode again based on whether the shooting scene is a high-dynamic scene, the graph mode can be flexibly switched, the graph of the iDCG mode with higher power consumption can not be used in the whole recording process, and the power consumption of the electronic equipment can be saved.

A schematic software architecture diagram involved in the graph mode switching method in an electronic device is shown in fig. 6.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the system is divided into four layers, from top to bottom, an application layer, an application framework layer, a hardware abstraction layer, and a hardware layer, respectively.

The application layer may include a series of application packages, among other things. The application package may include a camera application. Other applications may be included in addition to camera applications, such as gallery applications and the like (which may also be referred to as applications).

A video mode may be included in the camera application. The video mode may be used to determine whether to turn on the scene detection function. After the recording mode is turned on, the camera application may interact with other layers in the recording mode.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 6, a camera framework layer may be included in the application framework layer that may provide APIs and programming frameworks for the camera application so that the camera application may interact with other layers.

The hardware abstraction layer is an interface layer located between the kernel layer (not shown) and the hardware layer, which aims at abstracting the hardware and providing a virtual hardware platform for the operating system.

The hardware abstraction layer may include abstraction layers of different hardware. For example, the abstraction layer of a camera. The hardware abstraction layer of the camera may include a front-end Image processing engine (IFE), an automatic exposure control (Auto Exposure Control, AEC) module, an intelligent scene detection algorithm (aivideo camera), a decision engine (multi camera), a pattern selection module (selectable sensor), and decision rule data related to the operation of the decision engine.

The intelligent scene detection algorithm is used for receiving an instruction for starting a scene detection function or an instruction for closing the scene detection function, which is sent in a video recording mode. When receiving an instruction for starting a scene detection function, the intelligent scene detection algorithm can determine whether a shooting scene is a high dynamic scene or not based on an exposure parameter (AE parameter) transmitted by an automatic exposure control module described below. The details of determining whether the shooting scene is a high dynamic scene based on the exposure parameter by the intelligent scene detection algorithm may refer to the following description of step S102, which is not repeated herein.

In some possible cases, the camera application may be notified to display a high dynamic indication icon in the event that the intelligent scene detection algorithm determines that the shooting scene is a high dynamic scene.

In other possible cases, the camera application may be notified to display the high dynamic indication icon if the intelligent scene detection algorithm determines that the shooting scene is a high dynamic scene and the preset display condition is satisfied. The preset display conditions include, but are not limited to, one or more of the following display conditions:

display condition 1: the zoom range meets the preset requirements. For example, the corresponding focal length when recording video is greater than or equal to the preset focal length. The preset focal length may be a focal length corresponding to a 1x zoom magnification, or may be other values, for example, a focal length corresponding to a 1.5x zoom magnification, which is not limited in the embodiment of the present application.

Display condition 2: the information of the camera module meets the preset requirement. The preset requirements may include that the camera that captures the image includes a main camera.

The intelligent scene detection algorithm may also be used to inform the decision engine if the shooting scene is a high dynamic scene.

In some possible cases, the intelligent scene detection algorithm may detect whether a shot scene is a high dynamic scene within a preset period. The preset period may be a time required to acquire an X frame image, and X may be an integer greater than or equal to 1. The processing capability of the electronic device may be specifically determined, which is not limited by the embodiment of the present application.

The front-end image processing engine can process the image output by the camera sensor to obtain a processed image, and the processed image is transmitted to the automatic exposure control module.

The front-end image processing engine may also be referred to as a front-end image processing engine, where possible.

The automatic exposure control module may determine exposure parameters based on the processed image and transmit the exposure parameters to an intelligent scene detection algorithm.

The decision engine may determine the pattern of the graph based on whether the captured scene is a highly dynamic scene or not and the decision rule data. In the case where it is determined that the photographed scene is a high dynamic scene and the high dynamic video mode may be turned on, the decision engine may determine that the graph mode is an iDCG mode. In the case where the shooting scene is determined to be a non-high dynamic scene, or where the shooting scene is determined to be a high dynamic scene and the high dynamic video mode may not be on, the decision engine may determine that the graph mode is a binding mode.

In some possible cases, the decision rule may be written in a configuration form in a config.xml file, which is placed at the hardware abstraction layer as decision rule data.

Wherein, the conditions for determining that the high dynamic video recording mode can be started include, but are not limited to, the following starting conditions:

opening condition 1: the zoom range meets the preset requirements. The opening condition 1 is the same as the display condition 1 described above, and reference is made to the description related to the foregoing, and details are not repeated here.

Opening condition 2: the information of the camera module meets the preset requirement. The opening condition 2 is the same as the display condition 2 described above, and reference is made to the description related to the foregoing, which is not repeated here.

Opening condition 3: the state of the high dynamic indication icon is state 1, and the high dynamic indication icon in state 1 indicates that a user starts a high dynamic video recording mode through the electronic equipment.

Other modules may be included in the abstraction layer of the camera, such as a multi-shot fusion engine (SAT), an image-processing engine engine (IPE), and an encoding (video) module. These modules may be used for the electronic device to process the acquired images to obtain video.

The pattern selection module may be configured to receive a pattern output by the decision engine during an image processing phase (request phase). And determining whether to switch the image pattern of the camera sensor based on the image pattern. When the graph mode received by the graph mode selection module is the same as the graph mode used by the current camera sensor, the graph mode of the camera sensor is not switched. And when the graph mode received by the graph mode selection module is different from the graph mode used by the current camera sensor, switching the graph mode of the camera sensor.

In some possible cases, the graph mode selection module may store the graph mode in metadata from which a driver corresponding to a subsequent camera sensor may acquire the graph mode.

In some possible cases, the join in marriage current phase diagram mode selection module has not yet received the diagram mode of decision engine output in the time that the camera just started. The picture mode of the picture mode selection module may default to a video mode, which is a binding mode.

The hardware layers may include different hardware. For example, may include a camera sensor.

The camera sensor may include therein a binding mode map module and an iDCG mode map module.

The binding mode image module processes the acquired image based on the binding mode to obtain a video. The iDCG mode map module processes the acquired images based on the iDCG mode to obtain video.

Fig. 7 shows an example diagram involved in the portioning phase.

Fig. 8 shows an example diagram involved in the image processing stage.

An exemplary process flow of the graph mode switching method will be specifically described with reference to fig. 6 to 8.

It should be understood here that steps 1-5 describe an exemplary procedure for switching the graph mode from the binding mode to the iDCG mode. The graph mode of the electronic device may be repeatedly switched, and other scenarios may refer to the following descriptions, which are not repeated here. After the electronic equipment is in the flow distribution, the electronic equipment can go from the flow distribution stage to the image processing stage without stopping flow and restarting flow.

Step 1, after the camera application enters a video recording mode, an intelligent scene detection algorithm is started to determine whether a shooting scene is a high dynamic scene. In addition, as shown in fig. 7, in the streaming phase, the picture mode selection module is set in the video mode to drive the camera sensor to process the acquired image based on the default on binding mode.

Step 1 is shown as gray circle mark (1) in fig. 6 and 7.

And step 2, after the intelligent scene detection algorithm is started, entering an image processing stage. The front-end image processing engine obtains a processed image based on the image output by the camera sensor and transmits the processed image to the automatic exposure control module. As shown in fig. 8, the automatic exposure control module determines an exposure parameter based on the processed image and transmits the exposure parameter to the automatic exposure control module. The intelligent scene detection algorithm identifies whether the photographed scene is a highly dynamic scene based on the exposure parameters.

Step 2 is shown as gray circle mark (2) in fig. 6 and 8.

Step 3, as shown in fig. 8, in the case that the intelligent scene detection algorithm determines that the shooting scene is a high dynamic scene, the camera application is notified to display a high dynamic indication icon.

Step 3 is shown as gray circle mark (3) in fig. 6 and 8.

Step 4, as shown in fig. 8, the decision engine may determine that the graph mode is the iDCG mode based on the shooting scene being a high dynamic scene and the decision rule data.

Step 4 is shown as a gray circle in fig. 6 and 8 (4).

Step 5, as shown in fig. 8, the decision engine sends an instruction that the graph mode is the iDCG mode to the graph mode selection module, which switches the graph mode to the iDCG mode. And driving the camera sensor to process the acquired image based on the iDCG mode graph module to obtain a video.

Step 5 is shown as gray circle mark (5) in fig. 6 and 8.

Fig. 9 shows an exemplary flowchart of a graph mode switching method in an embodiment of the present application.

For details of the graph mode switching method in the embodiment of the present application, reference may be made to the following description of step S101 to step S110.

S101, the electronic equipment enters a video recording mode, and a scene detection function is started in the preview process.

After the electronic device turns on the scene detection function, the following step S102 may be executed to determine whether the shooting scene is a high dynamic scene.

The electronic device enters a video recording mode and one exemplary user interface involved in turning on the scene detection function during the preview process may be the user interface 31 described above in relation to (2) of fig. 3A. The smart detection indicator 211 (the display state is state B) displayed by the user interface 31 may indicate that the electronic device turns on the scene detection function.

It should be appreciated that the user may turn the scene detection function off or on via the smart detection indicator 211.

The manner in which the electronic device turns on the scene detection function includes, but is not limited to, one of the following.

Mode 1: the scene detection function is turned on by default.

Mode 2: the user may turn on the scene detection function via the electronic device.

Mode 3: and under the condition that the main camera is opened, starting the scene detection function.

S102, the electronic equipment acquires exposure parameters corresponding to the time A, and determines whether a shooting scene corresponding to the time A is a high dynamic scene or not based on the exposure parameters.

In some possible cases, the exposure parameters may include one or more of the following: ambient light intensity, automatic dynamic compression range (adrcGain), and dark area brightness (dark) corresponding to field of view (FOV) of an electronic device.

The time a may be understood as the time before the electronic device displays a high dynamic indicator icon (e.g., a high dynamic indicator icon of state 1).

The illumination intensity corresponding to the field angle is used for indicating the illumination intensity in the field angle range of the electronic equipment.

The automatic dynamic compression range may be used to indicate a difference in brightness between a target bright area and a target dark area in an image acquired by the electronic device. The automatic dynamic compression range may describe a contrast relationship between the brightest region and the darkest region in one frame of image. The target bright area may include pixels in the image where the sum of consecutive T color channel values (RGB values) is maximum. The target dim light zone may include a pixel in the image where the sum of consecutive T color channel values (RGB values) is minimum.

The dark region brightness may be used to indicate the brightness value corresponding to the darker pixel in a frame of image. Which may be expressed as an average luminance value of all pixel colors smaller than a preset color channel value (RGB value) in one frame image. In the case where the RGB values take on values of 0 to 255, the preset RGB values may be set to 40 to 60 or the like, for example, 50.

Wherein the units corresponding to the luminance involved in the different parameters may be lux.

The exposure parameters corresponding to the time a are described herein as examples including the ambient light brightness corresponding to the time a, the automatic dynamic compression range corresponding to the time a, and the dark area brightness corresponding to the time a. When the ambient light brightness corresponding to the time A comprises the time A, the illumination intensity in the field angle range of the electronic equipment. The automatic dynamic compression range corresponding to the time A comprises a brightness difference value between the target bright area and the target dark area in the image acquired by the electronic equipment at the time A. The dark area brightness corresponding to the time A comprises the average brightness value of all pixel colors in the image acquired by the time A, which is smaller than the preset color channel value (RGB value). The time a may be a time or a period of time.

In some possible cases, the rule for the electronic device to determine whether the shooting scene corresponding to the time a is a high dynamic scene based on the exposure parameter corresponding to the time a includes, but is not limited to, one or more of the following rules.

Determining rule 1: the electronic device may determine whether the shooting scene corresponding to the time a is a high dynamic scene based on the ambient light level corresponding to the time a and the automatic dynamic compression range corresponding to the time a.

Specifically, when the electronic device determines that the ambient light brightness corresponding to the time a is greater than or equal to the preset value A1 (for example, 15×w11), and the automatic dynamic compression range corresponding to the time a is greater than or equal to the preset value B1 (for example, 3×w21), the electronic device determines that the shooting scene corresponding to the time a is a high dynamic scene.

When the electronic device determines that the ambient light brightness corresponding to the time a is greater than or equal to the preset value A1 and the automatic dynamic compression range corresponding to the time a is smaller than the preset value B2 (for example, 3×w22), the electronic device determines that the shooting scene corresponding to the time a is a non-high dynamic scene.

In some possible cases, when the ambient light level is represented in the range of 0-100, the preset value A1 and the preset value A2 may be represented as 15×w11.

Wherein, the values of w1, w21, w22, w31 and w32 can be close to 1 or equal to 1, and w21 is larger than or equal to w22, and w31 is larger than or equal to w 32. The values of w21 and w31 may be greater than 1, for example, 1.1 and 1.2. The values of w22 and w32 may be less than 1, for example, 0.9, 0.8, etc. The values of w1, w21, and w31 may be different or the same (e.g., 1). The values of w1, w22 and w32 may be different or the same (e.g., 1). The embodiment of the present application is not limited thereto.

In the determination rule 1, the preset value A1 is greater than or equal to the preset value A2. The preset value B1 is greater than or equal to the preset value B2, and the preset value C1 is greater than or equal to the preset value C2. When one of the preset value A1, the preset value B1 and the preset value C1 is greater than the preset value A2, the preset value B2 and the preset value C2, the "strict entering and wide exiting" is indicated. For example, when the preset value C1 is greater than the preset value C2 and/or the preset value B1 is greater than the preset value B2, the "strict in and wide out" is indicated, that is, after the high dynamic scene is determined, the non-high dynamic scene is not cut in quickly. Or, after being determined as a non-high dynamic scene, the high dynamic scene is not cut in quickly. The problem of switching back and forth between high dynamic scenes and non-high dynamic scenes is avoided.

Determining rule 2: the electronic device may determine whether the shooting scene corresponding to the time a is a high dynamic scene based on the ambient light brightness corresponding to the time a and the dark area brightness corresponding to the time a.

Specifically, when the electronic device determines that the ambient light brightness corresponding to the time a is greater than or equal to the preset value A1 (for example, 15×w11), and the dark area brightness corresponding to the time a is greater than or equal to the preset value C1 (for example, 30×w31), the electronic device determines that the shooting scene corresponding to the time a is a high dynamic scene.

When the electronic device determines that the ambient light brightness corresponding to the time a is greater than or equal to the preset value A1 and the automatic dynamic compression range corresponding to the time a is smaller than the preset value C2 (for example, 30×w32), the electronic device determines that the shooting scene corresponding to the time a is a non-high dynamic scene.

Determining rule 3: and under the condition that the ambient light brightness corresponding to the electronic equipment determining time A is smaller than a preset value A2 (for example, 15 x w 11), the electronic equipment determining time A corresponds to a shooting scene which is a non-high dynamic scene. The preset value A2 is greater than or equal to the preset value A1.

Determining rule 4: under the condition that the electronic device determines that the shooting scene corresponding to the time A is a non-high dynamic scene based on the ambient light brightness corresponding to the time A and/or the automatic dynamic compression range corresponding to the time A, the electronic device can determine whether the shooting scene corresponding to the time A is a high dynamic scene or not based on the ambient light brightness corresponding to the time A and the dark area brightness corresponding to the time A again. The procedure is the same as the determination rule 2, and will not be described here again.

The process of determining that the shooting scene corresponding to the time a is a non-high dynamic scene based on the ambient light brightness corresponding to the time a and/or the automatic dynamic compression range corresponding to the time a by the electronic device may refer to the description of the determination rule 1-the determination rule 3, which is not repeated herein. Other determining methods may be used, for example, when it is determined that the ambient light brightness corresponding to the time a is less than the preset value A2, or the automatic dynamic compression range corresponding to the time a is less than the preset value C2, the electronic device determines that the shooting scene corresponding to the time a is a non-high dynamic scene. Then, the electronic device may determine whether the shooting scene corresponding to the time a is a high dynamic scene based on the ambient light brightness corresponding to the time a and the dark area brightness corresponding to the time a again. For example, specifically, when the electronic device determines that the ambient light intensity corresponding to the time a is greater than or equal to the preset value A1 (for example, 10×w11), and the dark area brightness corresponding to the time a is greater than or equal to the preset value C1 (for example, 30×w31), the electronic device determines that the shooting scene corresponding to the time a is a high dynamic scene.

It should be understood that the foregoing references 15, 3, and 30 are all illustrative, and in practical cases, other values may be used, which are not limited by the embodiment of the present application.

It should be understood here that in step S102, determination of rule 2 may be regarded as correction of determination rule 1. In the case of a decision rule 1 misjudgment, correction may be made based on a decision rule 2. For example, in a case where the photographing scene is a high dynamic scene but it is determined that the photographing scene is a non-high dynamic scene based on the determination rule 1, it may be determined that the photographing scene is a high dynamic scene again based on the determination rule 2.

This step S102 may be implemented based on the intelligent scene detection algorithm and its related modules as previously described. For specific description, reference may be made to the foregoing, for example, reference is made to the foregoing description of step 2, and details are not repeated here.
