Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, "/" means or is meant unless otherwise indicated, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating 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. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

For ease of understanding, the terms referred to in the embodiments of the present application are presented herein:

1) User experience (UX): may also be referred to as UX feature, which refers to the perception of a user using an electronic device during a shooting process.

2) Film mode: refers to a mode in which the electronic device records video. In the embodiment of the application, the movie mode includes a 4K high-dynamic range (HDR) function and a look-up table (LUT) function, and when a user selects the movie mode to record video, the recorded video can have the texture of a movie, so that the picture is more stereoscopic.

3) 4K HDR: the HDR technology is added on the basis of 4K resolution, so that photographed pictures can show more real effects and are more similar to real pictures visible to human eyes. In some embodiments, the bright portions of the picture taken with the 4K HDR functionality are not overexposed and the dark portion details are clearly visible.

4) LUT: which may also be referred to as LUT files or LUT parameters, is a color conversion template, such as a mapping table of Red Green Blue (RGB). The LUT can change the gray value of the pixel actually sampled into another gray value corresponding to the gray value through certain conversion (such as threshold value, inversion, contrast adjustment, linear conversion and the like), so that the LUT can play a role in highlighting the useful information of the image and enhancing the optical contrast of the image.

An image includes a number of pixels, each represented by RGB values. The display screen of the electronic device may display the image according to the RGB values for each pixel in the image. That is, these RGB values will indicate how the display will illuminate to blend in a wide variety of colors for presentation to the user.

The LUT is an RGB mapping table, which is used to characterize the correspondence between RGB values before and after adjustment. For example, please refer to table 1, which shows an example of a LUT.

TABLE 1

When the original RGB value is (14, 22, 24), the output RGB value is (6,9,4) through the mapping of the LUT shown in table 1. When the original RGB values are (61, 34, 67), the output RGB values are (66, 17, 47) through the mapping of the LUT shown in table 1. When the original RGB values are (94, 14, 171), the output RGB values are (117, 82, 187) through the mapping of the LUT shown in table 1. When the original RGB values are (241, 216, 222), the output RGB values are (255, 247, 243) through the mapping of the LUT shown in table 1.

When the same image is processed by using different LUTs, different style image effects can be obtained. For example, LUT1, LUT2, and LUT3 shown in fig. 1 are different color lookup tables. The LUT1 is used to process the original image 100 acquired by the camera to obtain the image 101 shown in fig. 1. The LUT2 is used to process the raw image 100 acquired by the camera to obtain the image 102 shown in fig. 1. The LUT3 is used to process the original image 100 acquired by the camera to obtain the image 103 shown in fig. 1. Comparing the image 101, the image 102, and the image 103 shown in fig. 1, it can be seen that the image 101, the image 102, and the image 103 have different image effects or styles.

In the conventional technology, when the electronic equipment records video, the recording function of the electronic equipment does not comprise a 4K HDR function and an LUT function; moreover, the shooting mode of the electronic equipment does not include a movie mode, so that the style or effect of the video recorded by the electronic equipment is single, the current diversified shooting requirements of users cannot be met, and the user experience is poor.

The embodiment of the application provides a shooting method which can be applied to electronic equipment comprising a camera and a display screen. The method can enrich shooting effects obtained by video recording, can meet the diversified shooting requirements of current users, and further improves user experience.

The camera of the electronic device includes a first function and a second function. When the user selects the first function, the electronic device can present video effects or styles corresponding to different LUTs in the video recording process. And when the user selects the second function at the same time, the definition of the image shot by the electronic equipment can be higher and more vivid.

The first function may be, for example, a LUT function; the second function may be, for example, a 4K HDR function.

Taking the electronic device as a mobile phone as an example, in some embodiments, as shown in fig. 2 (1), the function of recording video by the mobile phone may be implemented in a video recording mode of a camera of the mobile phone. In other embodiments, as shown in fig. 2 (2), the function of recording video by the mobile phone may be implemented in a professional mode of the camera of the mobile phone. In still other embodiments, as shown in fig. 2 (3), the function of recording video by the mobile phone may be implemented in a movie mode of the camera of the mobile phone.

As also shown in fig. 2 (1), in some embodiments, the cell phone displays an interface 201 in video mode. In other embodiments, in interface 201, the video mode includes a LUT control for initiating LUT functionality. It should be noted that (1) in fig. 2 in the embodiment of the present application does not illustrate the LUT control.

In some embodiments, the video mode further includes an HDR setup for initiating a 4K HDR function. For example, as shown in fig. 3 (1), after the mobile phone enters the video mode, the mobile phone displays the interface 201 in the video mode. The interface 201 includes a setting item 206 therein. In response to the user's operation of the setting item 206, the cellular phone displays a setting interface 207 as shown in (2) in fig. 3, the setting interface 207 including a "photo scale" setting item, a "sound control photographing" setting item, a "smiling face snapshot" setting item, a "video resolution" setting item, a "video frame rate" setting item, a "video HDR10" setting item 208, a "high-efficiency video format" setting item, an "AI movie hue" setting item, and the like. In response to a user's start operation of the "video HDR10" setting item 208, the handset displays a setting interface 209 as shown in fig. 3 (3). In this setup interface 209, the "video HDR10" setup item is turned on, i.e. the handset has enabled the 4K HDR function in video mode.

As also shown in fig. 2 (2), the handset displays the interface 202 in the professional mode. The interface 202 includes a LUT control 203 for initiating LUT functionality. After the user turns on the LUT control 203, the handset starts the LUT function. In some embodiments, interface 202 also includes LOG control a for launching LOG functions. Since the video image shot by the LOG function is gray in color by the mobile phone camera and the video image shot by the LUT function is rich in color, the LOG control a and the LUT control 203 included in the interface 202 cannot be opened at the same time. That is, in the professional mode of the cellular phone camera, the LOG function and the LUT function cannot be simultaneously operated. Note that, the LUT control 203 shown in (2) in fig. 2 is in the off state.

In some embodiments, the professional mode further includes an HDR setup for initiating a 4K HDR function. For example, as shown in fig. 4 (1), after the mobile phone enters the professional mode, the mobile phone displays the interface 203 in the video mode. The interface 203 includes a setting item 206 therein. In response to the user's operation on the setting item 206, the mobile phone displays a setting interface 210 as shown in (2) in fig. 4, where the setting interface 210 includes a "photo scale" setting item, a "sound control photographing" setting item, a "smiling face snapshot" setting item, a "video resolution" setting item, a "video frame rate" setting item, a "professional video HDR10" setting item 211, a "high-efficiency video format" setting item, an "AI movie hue" setting item, and the like. In response to a user's start operation of the "professional video HDR10" setting item 211, the mobile phone displays a setting interface 212 as shown in (3) in fig. 4. In this setup interface 212, the "professional video HDR10" setup is turned on, i.e. the handset has enabled the 4K HDR function in professional mode.

As also shown in fig. 2 (3), the handset displays the interface 204 in movie mode. Included in this interface 204 are LUT controls 203 for launching LUT functionality and 4K HDR controls 205 for launching 4K HDR functionality.

The electronic device 100 may implement photographing functions through an ISP, a camera 193, a video codec, a GPU, a display screen 194, an application processor, and the like.

The ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and is converted into an image visible to naked eyes. ISP can also optimize the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, the electronic device may include 1 or N cameras 193, N being a positive integer greater than 1.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to enable expansion of the memory capabilities of the electronic device. The external memory card communicates with the processor 110 through an external memory interface 120 to implement data storage functions. For example, audio, video, etc. files are stored in an external memory card.

The internal memory 121 may be used to store computer executable program code including instructions. The processor 110 executes various functional applications of the electronic device and data processing by executing instructions stored in the internal memory 121.

The methods in the following embodiments may be implemented in the electronic device 100 having the above-described hardware structure. In the following embodiments, the electronic device 100 is taken as an example of a mobile phone, and the technical solutions provided in the embodiments of the present application are specifically described.

In the following embodiments, a new movie mode is taken as an example in a mobile phone camera. It should be understood that the movie mode is one mode in which the cell phone records video.

In one possible implementation manner, the user can select the corresponding LUT according to different shooting scenes, so that the styles or effects of the images shot by the different shooting scenes are different, thereby enriching the styles or effects of the shooting of the mobile phone, and enabling the shooting effects to be more diversified and personalized. Wherein, shooting scene can be: a person scene, a travel scene, a food scene, a landscape scene, a person scene, a pet scene, a still scene, or the like. Of course, the shooting scene may be other scenes, which are not listed here.

In some embodiments, as shown in fig. 6 (1), in response to a user operating an icon 301 of a "camera" application in the mobile phone home screen interface, the mobile phone displays an interface 302 as shown in fig. 6 (2). The interface 302 is a preview interface of mobile phone photographing, and the interface 302 further includes a "portrait" mode, a "video" mode, a "movie" mode, and a "professional" mode. In response to the user selecting the "movie" mode 303, the mobile phone displays an interface 304 as shown in fig. 7 (1). The interface 304 is a preview interface before video recording of the mobile phone. In interface 304, the handset displays a prompt 305. The prompt information 305 is used to prompt the user to place the mobile phone in a landscape state. For example, the prompt 305 may be "movie mode cross screen shooting effect is better". Then, when the user places the mobile phone in the landscape state, the mobile phone displays an interface 306 as shown in fig. 7 (2). The interface 306 is a preview interface before video recording in a horizontal screen state of the mobile phone.

Also shown as interface 306 in fig. 7 (2), interface 306 includes 4K HDR control 205 and LUT control 203. In some embodiments, as shown in fig. 8 (1), in response to a user operation of LUT control 203, the handset displays an interface 307 as shown in fig. 8 (2). The interface 307 includes LUT templates 308; the LUT templates 308 include LUT1, LUT2, LUT3, and LUT8, among others.

Note that, in the case where the mobile phone camera enters the movie mode, the LUT control 203 is always in an on state. In other words, after the mobile phone camera enters the movie mode, the LUT function is turned on by default, and the default LUT is selected to process the preview image. In some embodiments, the default LUT is typically LUT1.

In the present embodiment, the color depth (which may also be referred to as hue) of different LUTs is different. Illustratively, from LUT1 to LUT8, the tone of the LUT is gradually changed from a warm tone to a cool tone in sequence; alternatively, from LUT1 to LUT8, the tone of the LUT gradually changes from the cool tone to the warm tone in order. The embodiments of the present application are not limited in this regard.

In some embodiments, LUT1 may be named "city of things," LUT2 may be named "early spring of cherry," LUT3 may be named "nine zero years," and LUT4 may be named "twilight city. Of course, other LUTs included in the LUT template 308 may also be named and are not listed here. In addition, the above-described naming of the LUT is merely an example of the embodiment of the present application, and is not meant to limit the present application.

In some embodiments, the preview interface includes a preview image captured by a camera of the cell phone. The preview image may be a person image, a travel image, a landscape image, a pet image, or the like. The user may select different LUTs based on different preview images. For example, when the preview image is a person scene, the user may select LUT1 (city of travel) to process the preview image to obtain a corresponding photographing effect or style. When the preview image is a travel scene, the user can select LUT2 (early spring of cherry) to process the preview image to obtain a corresponding photographing effect or style. It can be understood that under different preview images, the corresponding LUT can be adopted to process the preview images to obtain corresponding shooting effects or styles, so that the styles and effects of the shooting images of the mobile phone are enriched, and the diversified shooting requirements of the current user are met.

Taking the LUT1 as an example of processing the preview image by the user, when the user processes the preview image by using the LUT1, the mobile phone may transform the RGB value (i.e., the gray value) of each of the plurality of pixels included in the unprocessed preview image to a certain extent, so that the RGB value of each of the plurality of pixels included in the processed preview image is different from the RGB value of each of the plurality of pixels included in the unprocessed preview image, that is, the brightness of each of the plurality of pixels included in the processed preview image is different from the brightness of each of the plurality of pixels included in the unprocessed preview image 402, thereby playing a role of highlighting the useful information of the image and enhancing the optical contrast of the image, so that the color of the processed preview image is darker and the figure outline is clearer.

In some embodiments, in response to a user operation of 4K HDR control 205, based on interface 307 shown in fig. 8 (2), the handset displays interface 309 shown in fig. 8 (3). Wherein the interface 309 includes LUT templates 310; the LUT templates 310 include LUT9, LUT10, LUT11, and LUT16.

Note that the 4K HDR control 205 shown in (2) in fig. 8 and the 4K HDR control 205 shown in (3) in fig. 8 are in different states. For example, 4K HDR control 205 shown in (2) in fig. 8 is in an off state, and 4K HDR control 205 shown in (3) in fig. 8 is in an on state.

In some embodiments, LUT templates 308 are 8bit templates when 4K HDR control 205 is in an off state; LUT templates 310 are 10bit templates when 4K HDR control 205 is in an on state. Wherein, 8 bits represent 256 gray levels, 10 bits represent 1024 gray levels, the more the gray level number is, the finer the color is, and the more uniform and natural the color transition is. Thus, when the user selects LUT template 310, i.e., the user opens 4K HDR control 205, selecting the 4K HDR function, the image captured by the phone will be clearer and the color will be more vivid.

Illustratively, when the 4K HDR control 205 is actuated by the user, the LUT templates 310 are 10bit templates, i.e., the LUTs included in the LUT templates 310 are all 10bit, so that each LUT included in the LUT templates 310 can display 1024 gray scales. In this way, when the LUT in the LUT template 310 is used to process the image, the mobile phone may perform a certain transformation on the RGB value of each of the plurality of pixels included in the unprocessed preview image, so that the RGB value of each of the plurality of pixels included in the processed image is different from the RGB value of each of the pixels of the previous image, and, since the LUT template 310 is a 10bit template, after the LUT in the LUT template 310 is converted, the color of the processed image is richer, the color transition is more uniform and natural, and the preview image processed by the mobile phone using the LUT of 10 bits is clearer.

The LUT1, LUT2, LUT3, and LUT 4 included in the LUT template 308 correspond to the LUT9, LUT10, LUT11, and LUT16 included in the LUT template 310 one by one. For example, LUT1 corresponds to LUT9, LUT2 corresponds to LUT10, LUT3 corresponds to LUT11, LUT8 corresponds to LUT16, and so on. In other words, when LUT1 is "city address", LUT9 is also "city address"; however, since the LUT9 is 10 bits and the LUT1 is 8 bits, the LUT9 has finer color and more uniform and natural color transition than the LUT 1.

In other embodiments, the handset further includes an HDR setup for enabling 4K HDR functionality. For example, as shown in fig. 9 (1), the mobile phone displays an interface 306 in the movie mode, and the interface 306 is a preview interface before the mobile phone enters the video recording in the movie mode. The interface 306 includes a setting item 401, and in response to a user's operation of the setting item 401, the cellular phone displays a setting interface 402 as shown in (2) in fig. 9. The setting interface 402 includes a "photo scale" setting item, a "sound control photographing" setting item, a "smiling face snapshot" setting item, a "video resolution" setting item, a "video frame rate" setting item, a "movie HDR10" setting item, a "high-efficiency video format" setting item, an "AI movie hue" setting item 403, and the like. In response to a user start operation of the "movie HDR10" setting item, the "movie HDR10" setting item is turned on, i.e. the handset starts the 4K HDR function.

Considering that when a user shoots, if a shooting scene is complex, the user does not know which LUT effect to select is better in many times, based on this, in another possible implementation manner, the user can select an artificial intelligence (artificial intelligence, AI) model, identify a preview image included in a preview interface before the mobile phone video recording by the AI model, and match an LUT corresponding to the preview image, so that the mobile phone can automatically select the LUT according to the identified preview image, and the user selection is not needed while enriching the style or effect of mobile phone shooting, thereby further improving the user experience. Wherein the AI model may be any machine model for identifying the preview image. For example, the AI model may be any of the following neural network models: VGG-net, resnet, and Lenet.

In some embodiments, as shown in fig. 6 (1), in response to a user operating an icon 301 of a "camera" application in the mobile phone home screen interface, the mobile phone displays an interface 302 as shown in fig. 6 (2). The interface 302 is a preview interface of mobile phone photographing, and the interface 302 includes a "portrait" mode, a "video" mode, a "movie" mode, and a "professional" mode. In response to the user selecting the "movie" mode 303, the mobile phone displays an interface 306 as shown in fig. 9 (1). The interface 306 is a preview interface before video recording of the mobile phone.

Also shown as interface 306 in fig. 9 (1), interface 306 includes 4K HDR control 205, LUT control 203, and settings items 401. In some embodiments, as shown in fig. 9 (1), in response to the user's operation of the setting item 401, the mobile phone displays a setting interface 402 as shown in fig. 9 (2), the setting interface 402 including a "photo scale" setting item, a "sound control photographing" setting item, a "smiling face snapshot" setting item, a "video resolution" setting item, a "video frame rate" setting item, a "movie HDR10" setting item, a "high efficiency video format" setting item, and a "AI movie hue" setting item 403, and the like. In response to the user's activation operation of the "AI movie tint" setting item 403, the mobile phone displays a setting interface 404 as shown in fig. 9 (3), in which setting interface 404 the "AI movie tint" setting item is opened, i.e., the mobile phone activates the AI model recognition preview image.

In some embodiments, as shown in fig. 10 (1), in the interface 404, after the AI movie tint "setting item is opened, the handset displays an interface 405 as shown in fig. 10 (2) in response to a user's return operation to the interface 404 (e.g., a user clicking on a return arrow of the setting item in the interface 404). Wherein the interface 405 identifies a dynamic interface of the preview image for the AI model, the interface 405 includes indication information for characterizing the identification process. The indication information may be, for example, an icon. Such as circles of different sizes and different transparency shown in interface 405 of fig. 10 (2).

Then, after the recognition process is finished, the mobile phone displays an interface 406 as shown in (3) in fig. 10, and the interface 406 is a LUT pattern matched with the preview image after the preview image is recognized by the mobile phone. Illustratively, the interface 406 includes a LUT template 407. The LUT template 407 includes, in order from left to right, an LUT icon, an LUT, and an "x" flag. Note that the LUT icon is an icon of the LUT control 203. The LUT included in the LUT template 407 may be, for example, LUT8, specifically, the LUT matched with the preview image after the preview image is identified by the AI model, which is not limited in this embodiment of the present application.

By way of example, LUT8 may be named "morning light," or other suitable name, to which embodiments of the present application are not limited.

In some embodiments, as shown in fig. 11 (1), if the user does not need an LUT to which the AI model matches, the handset may respond to the user's operation of the "x" flag, and the handset displays an interface 408 as shown in fig. 11 (2). The interface 408 exits the LUT template 407 for the handset. And simultaneously, the mobile phone adopts a default LUT to process the preview image of the preview interface. In general, the default LUT is LUT1.

It should be noted that, before the mobile phone does not start the AI model, after the mobile phone enters the movie mode, the mobile phone adopts a default LUT to process the preview image of the preview interface.

It will be appreciated that the LUT templates 407 shown in (3) in fig. 10 and the LUT templates 407 shown in (1) in fig. 11 are LUT templates for preview image matching after the preview images are identified for the AI model. In some embodiments, LUT template 407 includes only one LUT (e.g., LUT 8). In other embodiments, if the scene of the preview image is more complex (e.g., the scene of the preview image includes a person scene, a pet scene, a scenery, etc.), the LUT template 407 may include two or more LUTs (e.g., LUT1, LUT2, and LUT 8). In fig. 10 (3) and 11 (1), the LUT template 407 includes only one LUT as an example.

It should be appreciated that when the user initiates the AI model recognition preview image, if the 4K HDR control 205 is in an on state, the LUT template 407 to which the AI model is matched for the preview image includes one or more of LUT1, LUT2, LUT3, LUT 8. If 4K HDR control 205 is in an off state, LUT templates 407 to which the AI model matches for the preview image include one or more of LUT9, LUT10, LUT11, LUT 16.

In some embodiments, after the AI model matches to the LUT template corresponding to the preview image, the AI model may automatically select the LUT included in the LUT template to process the preview image. For example, when the AI model matches that the LUT template 407 corresponding to the preview image includes LUT8, the AI model may automatically select LUT8 to process the preview image. For another example, when the AI model is matched to the LUT template 407 corresponding to the preview image including LUT1, LUT2, and LUT8, the AI model may automatically select the LUT1 arranged at the first bit according to the arrangement order of the LUTs to process the preview image.

In other embodiments, after the AI model is matched to the LUT template corresponding to the preview image, the LUT included in the LUT template is selected by the user to process the preview image. For example, when the AI model is matched to the LUT template 407 corresponding to the preview image including the LUT8, the user selects the LUT8 to process the preview image. For another example, when the AI model is matched to the LUT template 407 corresponding to the preview image including LUT1, LUT2, and LUT8, the user can select a corresponding LUT (e.g., LUT 8) to process the preview image according to the scene, brightness, or user's own preference of the preview image.

When the user selects the LUT included in the LUT template himself, in some embodiments, as shown in (1) in fig. 12, in response to the user's operation of the LUT control 203, the handset displays an interface 409 as shown in (2) in fig. 12, the interface 409 including the LUT template 410. The LUT template 410 includes all LUTs. For example, LUT template 410 includes LUT1, LUT2, LUT3, LUT8. Alternatively, LUT template 410 includes LUT9, LUT10, LUT11, LUT16. The user may then select the LUT included in LUT template 410 to process the preview image. For example, the user may select according to the scene, brightness of the preview image, or preference of the user himself.

Note that when 4K HDR control 205 is in an unopened state, LUT template 410 includes LUT1, LUT2, LUT3, LUT8. When 4K HDR control 205 is in an on state, LUT template 410 includes LUT9, LUT10, LUT11, LUT16. Fig. 12 (2) illustrates an example in which the 4K HDR control 205 is in an unopened state, and the LUT template 410 includes LUT1, LUT2, LUT3, and LUT8.

In the case where the cell phone camera initiates the AI model, in some embodiments, the AI model may periodically identify the preview image and match the LUT corresponding to the preview image. For example, the AI model may identify preview images once every preset time period; the preset duration may be, for example, 3 seconds, 5 seconds, or 10 seconds. Of course, the preset duration may be other suitable durations, which are not limited in this embodiment of the present application. Considering that if the scene of the video image collected by the camera is frequently switched, the AI model always identifies the video image and matches with the LUT corresponding to the video image, thereby affecting the video shooting effect. Based on this, in some embodiments, the AI model periodically recognizes the preview image before the handset begins recording video. When the mobile phone starts recording, the AI model stops identifying, so that the problem that the LUT frequently recommends and influences the video shooting effect in the video recording process of the mobile phone can be avoided.

In some embodiments, when a preview image changes, the AI model automatically switches the LUT corresponding to the changed preview image. For example, when the preview image is changed from "person scene" to "landscape scene", the AI model may switch the LUT from "LUT1" to "LUT5".

In other embodiments, the preview interface of the handset further includes indication information when the preview image changes. The indication information is used to prompt the user whether to switch the LUT. For example, after the AI model recognizes that the preview image has changed (e.g., from a person scene to a landscape scene), the handset sends instruction information to the user, which is displayed in the preview interface of the handset. The indication information may be an icon, or text, for example.

For example, before the preview image is changed, the mobile phone displays an interface 501 as shown in fig. 13 (1). The scene of the preview image in the interface 501 is a person scene, and the LUT for the AI model matching the preview image is LUT2. Accordingly, after the preview image is changed, the mobile phone displays an interface 502 as shown in fig. 13 (2). The scene of the preview image in the interface 502 is a landscape scene, and the instruction information displayed in the interface 502 is an LUT icon (e.g., LUT 5) 503. In some embodiments, LUT icon 503 may be displayed in interface 502 for a period of time (e.g., 10 seconds), and in response to a user selecting LUT icon 503, the handset switches LUT2 to LUT5; if the user does not operate LUT icon 503 within 10 seconds, the user is instructed to refuse to switch, at which point the handset may continue to process the preview image using LUT2. In other embodiments, LUT icon 503 may be displayed in an interface 502 in a persistent dynamic state, with the cell phone switching LUT2 to LUT5 in response to a user selection of LUT icon 503; in response to the user's operation of the blank portion of interface 502, the handset exits the display of LUT icon 503, indicating that the user refuses to switch, at which point the handset may continue to process the preview image in accordance with LUT2. The blank portion in the interface 502 refers to a portion of the interface 502 other than the LUT icon 503.

For another example, before the preview image is changed, the mobile phone displays an interface 504 as shown in fig. 14 (1). The scene of the preview image in the interface 504 is a person scene and the LUT for the AI model matching the preview image is LUT2. Accordingly, after the preview image is changed, the mobile phone displays an interface 505 as shown in fig. 14 (2). The scene of the preview image in the interface 505 is a landscape, and the instruction information displayed in the interface 505 is text information. For example, the text information is "LUT5 is more suitable for the current shooting scene, and whether to switch to LUT5". In some embodiments, if the user selects the "ok" control, the handset switches LUT2 to LUT5 and uses LUT5 to process the preview image. If the user selects the cancel control, the mobile phone still adopts LUT2 to process the preview image.

In this embodiment, after the AI model recognizes that the preview image changes, the mobile phone may send instruction information to the user to prompt the user whether to switch the LUT, so as to improve the user experience while enriching the shooting style or effect.

In some embodiments, the handset displays interface 601 shown in fig. 15 (1). The interface 601 is a preview interface of the cell phone camera before recording. In response to the user's operation of the virtual shutter key 602, the cellular phone displays an interface 603 as shown in (2) in fig. 15. The interface is the interface when the mobile phone camera starts recording. Wherein the virtual shutter key 602 is a key for starting video recording and ending video recording

It should be noted that, in the foregoing embodiments, a new movie mode is mainly taken as an example in the mobile phone camera, and other modes may be newly added in the mobile phone camera at present, where the other modes may also adopt the first function and the second function to achieve the technical effects in the embodiments of the present application, which are not repeated herein.

In some embodiments, the software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, or a cloud architecture. In this embodiment, taking a layered architecture Android system as an example, a software structure of the electronic device 100 is illustrated.

Fig. 16 is a software structure diagram of an electronic device according to an embodiment of the present application.

It will be appreciated that the layered architecture divides the software into several layers, each with a clear role and division. The layers communicate with each other through a software interface. In some embodiments, the Android system may include an application layer (APP), a framework layer (FWK), a hardware abstraction layer (hardware abstraction layer, HAL), and a kernel layer (kernel). In some embodiments, the handset also includes hardware (e.g., a display screen).

Exemplary such application layers may include a User Interface (UI) layer and a logic layer. As shown in fig. 16, the UI layer includes cameras, gallery, and other applications. Wherein the camera includes a LUT control (e.g., LUT control 203 in the above embodiments), a 4K HDR control (e.g., 4K HDR control 205 in the above embodiments), and an AI settings item (e.g., AI movie hue in the above embodiments). The logic layer comprises an LUT template module, an encoding module, an LUT control module, an AI recommending module, an HDR module, a configuration library and the like.

The hardware abstraction layer is an interface layer between the kernel layer and the hardware, and can be used for abstracting the hardware. Illustratively, as shown in FIG. 16, the hardware abstraction layer includes a camera interface.

The kernel layer provides the bottom layer drive for various hardware of the mobile phone. Illustratively, as shown in FIG. 16, the kernel layer includes a camera driver module.

The framework layer provides application programming interfaces (application programming interface, APIs) and programming services for application programs of the application layer. The framework layer includes some predefined functions. The framework layer provides programming services to application layer calls through the API interface. It should be noted that, in the embodiment of the present application, the programming service may be, for example, a camera service (camera service). In some embodiments, as shown in fig. 16, the framework layer includes a camera service framework and a media framework. Wherein the media framework includes an encoder.

In a possible implementation manner, when the user selects the LUT to shoot according to different shooting scenes, the LUT template module is used to receive a start instruction of the LUT control and call the LUT template as shown in fig. 16. The HDR template is used for receiving a starting instruction of the 4K HDR control and starting the 4K HDR function. Illustratively, when 4K HDR is in an unopened state, the LUT templates invoked by the LUT template module include LUT1, LUT2, LUT3, LUT8; when 4K HDR is in an on state, the LUT templates called by the LUT template module include LUT9, LUT10, LUT11, LUT16. The LUT control module is used for receiving an instruction for determining a target LUT and calling a camera interface of the hardware abstraction layer to send a first instruction to the camera driving module; wherein the first instruction includes an identification of the target LUT; the first instruction is for instructing acquisition of a preview image of a camera preview interface. And the camera driving module acquires a preview image of the camera preview interface according to the first instruction, and invokes the camera interface of the hardware abstraction layer to send the preview image to the display screen so that the display screen displays the preview image. The preview image is an image with LUT effect.

The LUT template is a template pre-stored in the electronic device, and after the user clicks the LUT control, the LUT template module invokes the pre-stored template and displays the template on a display screen (for example, in a preview interface of the camera). In some embodiments, the internal logic of the handset application layer further includes a configuration library in which the LUT module is pre-stored.

Note that, when the target LUT selected by the user is LUT2, the first instruction includes the identification of the target LUT as 2.

When a user starts to record video, the camera driving module calls a camera interface of the hardware abstraction layer to report video frames of recorded video images to the coding module, so that the coding module codes according to the video frames. When the user finishes recording, the coding module stores the coded video image. The video image is an image with LUT effect, so the video frame is a video frame with LUT effect. For example, a video frame may include 1 to N frames; where 1 refers to the first frame at the beginning of recording and N refers to the last frame at the end of recording. In some embodiments, when a user starts recording, the camera driving module invokes the camera interface to report the 1 to N frames included in the video frame to the encoding module in sequence, and the encoding module encodes the 1 to N frames in sequence. And then, when the user finishes recording, the coding module stores the coded video frames of 1 to N frames, so that a video image with the LUT effect is obtained.

In some embodiments, when a user turns on the 4K HDR function, the photographing method provided in the embodiments of the present application will be described in detail with reference to the schematic structural diagram shown in fig. 19. Illustratively, the encoding module receives a start instruction for a 4K HDR control, setting parameters of an encoder in a media frame to 10 bits. Meanwhile, the camera service framework receives a starting instruction of the 4K HDR control and calls a camera interface of the hardware abstraction layer to send a first instruction to the camera driving module. And the camera driving module acquires a preview image of the camera preview interface according to the first instruction. In some embodiments, the camera driver module invokes a camera interface of the hardware abstraction layer to send the preview image onto the display screen to cause the display screen to display the preview image. The preview image is a preview image with a 10bit LUT effect. In other embodiments, the encoding module receives an instruction to start recording, the camera driving module invokes a camera interface of the hardware abstraction layer to send video frames of the recorded video image to the encoding module, and the encoding module invokes an encoder of a preset 10bit parameter in the media frame to encode the video frames of the video image and stores the encoded video image. Wherein, the video image is a video image with a 10bit LUT effect.

In another possible implementation manner, when the user starts the AI mode and the AI model selects the LUT to shoot according to different shooting scenes, the AI recommendation module receives a start instruction of the AI model and invokes the camera interface to acquire the scene and brightness of the preview image from the camera driving module, as shown in fig. 16. The camera driver module invokes the camera interface to send the scene and brightness of the preview image to the AI recommendation module. The AI recommendation module identifies the scene and brightness of the preview image and matches the LUT template corresponding to the preview image.

In some embodiments, the AI recommendation module automatically selects a target LUT and sends the selected target LUT to the LUT control module. The LUT control module calls a camera interface of the hardware abstraction layer to send a first instruction to the camera driving module. The first instruction includes an identification of a target LUT, and the first instruction is used for indicating acquisition of a preview image of a camera preview interface. And the camera driving module acquires a preview image of the camera preview interface according to the first instruction, and invokes the camera interface of the hardware abstraction layer to send the preview image to the display screen so that the display screen displays the preview image. The preview image is an image with LUT effect.

In other embodiments, when the user selects the target LUT himself, the LUT control module receives an instruction to determine the target LUT, invokes the camera interface of the hardware abstraction layer to send a first instruction to the camera driver module. And the camera driving module acquires a preview image of the camera preview interface according to the first instruction, and invokes the camera interface of the hardware abstraction layer to send the preview image to the display screen so that the display screen displays the preview image. The preview image is an image with LUT effect.

It should be noted that, the foregoing embodiments may be referred to for an illustration from when the user starts recording video to when the user ends recording video, which is not repeated here. In addition, reference may be made to the above embodiments for an illustration of the user after turning on the 4K HDR function, which is not described in detail herein.

In some embodiments, the AI recommendation module may identify the preview image periodically (i.e., every preset time period). If the scene and brightness of the preview image change, the AI recommendation module re-matches the LUT template corresponding to the preview image. The description of the identification of the preview scene by the AI recommendation module and the description of the matching of the LUT template corresponding to the preview image by the AI identification module may refer to the above embodiments, and will not be repeated herein.

In some embodiments, between the framework layer and HAL layer shown in fig. 16, a system library and runtime may also be included.

In the embodiment of the application, when the electronic device enters the camera application and is in the movie mode, the electronic device may execute the shooting method provided in the embodiment of the application. By way of example, taking the electronic device in fig. 16 as an example, a specific procedure of the photographing method is described, and in some embodiments, the photographing method may include steps S1 to S12 as shown in fig. 16 and 17.

S1, the electronic equipment receives a starting instruction of the LUT control through the LUT template module.

Illustratively, the electronic device generates the launch instruction in response to a user operation of the LUT control. And then, the electronic equipment sends a starting instruction of the LUT control to the LUT template module so that the LUT template module receives the starting instruction of the LUT control. The operation may be a voice operation, a touch operation, a gesture operation, or the like. The touch operation may be, for example, a click operation, a slide operation, or the like. The embodiments of the present application are not limited in this regard.

Correspondingly, after the LUT template module receives a starting instruction of the LUT control, the LUT template module calls the LUT template. Wherein the LUT template is pre-stored in the electronic device. For example, as shown in fig. 16, LUT templates may be stored in a configuration library. The LUT template includes a first LUT template and a second LUT template. It should be appreciated that when 4K HDR is in an unopened state, the LUT template invoked by the LUT template module is the first LUT template; the first LUT template includes LUT1, LUT2, LUT3, LUT8. When the 4K HDR is in an on state, the LUT template called by the LUT template module is a second LUT template; the second LUT template includes LUT9, LUT10, LUT11, LUT16.

s2b, the electronic equipment calls a second LUT template through the LUT template module.

S3b, the electronic equipment sends a second LUT template to the display screen through the LUT template module.

As also shown in fig. 17, when the 4K HDR is in the on state, the electronic device receives, through the HDR module, the start instruction of the 4K HDR control, and simultaneously sends, to the encoding module, the start instruction of the 4K HDR control. After the encoding module receives the start command of the 4KHDR control, the parameters of the encoder in the media frame are set to 10 bits.

With reference to any one of the foregoing embodiments, as shown in fig. 17, the photographing method provided in the embodiment of the present application further includes:

s5, the electronic equipment selects a target LUT through the LUT template module.

Illustratively, the electronic device selects the target LUT in response to a user operation of one of the LUTs in the LUT template.

It is understood that when the display screen of the electronic device displays the first LUT template, the target LUT selected by the LUT template module is one of the LUTs of the first LUT template. When the display screen of the electronic equipment displays the second LUT template, the target LUT selected by the LUT template module is one of the LUT of the second LUT template.

Taking the LUT template as the first LUT template as an example, the electronic device selects LUT2, that is, LUT2 as the target LUT, in response to the operation of the LUT2 in the first LUT template by the user. In some embodiments, after the LUT template module selects the target LUT, the electronic device sends the target LUT to the display screen via the LUT template module to cause the display screen to display the target LUT. In other embodiments, after the LUT template module selects the target LUT, the electronic device sends the target LUT to the LUT control module via the LUT template module.

S6, the electronic equipment sends the identification information of the target LUT to the camera driving module through the LUT control module. Illustratively, the LUT control module invokes the camera interface of the hardware abstraction layer to send the identification information of the target LUT to the camera driver module.

In some embodiments, when the target LUT is LUT2, the identification of the target LUT is 2.

S7, the electronic equipment acquires a preview image of the preview interface through the camera driving module according to the identification of the target LUT.

In some embodiments, when the 4K HDR is in an unopened state, the camera driver module obtains a preview image of the camera preview interface according to the identification information of the target LUT. It should be appreciated that the preview image is a preview image having an 8bit lut effect.

In other embodiments, when the 4K HDR is in an on state, the electronic device receives, through the HDR module, a start instruction of the 4K HDR control, and simultaneously sends the start instruction of the 4K HDR control to the camera service framework. And after receiving the starting instruction of the 4K HDR control, the camera service framework calls a camera interface of the hardware abstraction layer to send the identification information of the target LUT to the camera driving module. And the camera driving module acquires a preview image of the camera preview interface according to the identification information of the target LUT. It should be appreciated that the preview image is a preview image having a 10bit lut effect.

Correspondingly, after the camera driving module acquires the preview image, the preview image is sent to the display screen, so that the display screen displays the preview image. Illustratively, the camera driver module invokes the camera interface of the hardware abstraction layer to send the preview image to the display screen. It should be appreciated that the preview image is an image having a target LUT effect.

S8, the electronic equipment receives a recording starting instruction through the coding module.

Illustratively, the electronic device generates a start recording instruction in response to a user operation of the virtual shutter key. And then, the electronic equipment sends a recording starting instruction to the coding module so that the coding module receives the recording starting instruction. The virtual shutter key is a key for starting video recording and ending video recording. For example, as shown in (1) in fig. 15 in connection with the above embodiment, the virtual shutter key may be, for example, a control 602.

And S9, the electronic equipment sends the video frames of the recorded video images to the coding module through the camera driving module.

Illustratively, the camera driver module invokes the camera interface of the hardware abstraction layer to report video frames of the recorded video images to the encoding module.

S10, the electronic equipment encodes the video frames of the video image through the encoding module.

The video image is an image with a target LUT effect, so the video frame is a video frame with a target LUT effect. Illustratively, the video frames may include 1-N frames; where 1 refers to the first frame at the beginning of recording and N refers to the last frame at the end of recording. In some embodiments, the camera driver module invokes the camera interface to report the 1-N frames included in the video frame to the encoding module in sequence, and the encoding module encodes the 1-N frames in sequence.

In some embodiments, when the 4K HDR control is in an on state, the camera driver module invokes a camera interface of the hardware abstraction layer to send video frames of the recorded video image to the encoding module, and the encoding module invokes an encoder of a preset 10bit parameter in the media frame to encode the video frames of the video image and stores the encoded video image. Wherein, the video image is a video image with a 10bit LUT effect.

S11, the electronic equipment receives the recording ending instruction through the coding module.

Illustratively, the electronic device generates an end recording instruction in response to a user operation of the virtual shutter key. And then, the electronic equipment sends a recording ending instruction to the coding module so that the coding module receives the recording ending instruction.

S12, the electronic equipment stores the video image through the coding module.

As shown in connection with fig. 16, the electronic device may save the video image to a gallery of an application layer through an encoding module, for example.

In the embodiment of the application, since the film mode is added in the camera and comprises the LUT function and the 4K HDR function, when the user shoots in the film mode using the camera, the LUT function and the 4K HDR function can be selected to be started according to the scene, the brightness of the preview image or the preference of the user; when the user selects the LUT function, shooting effects or styles corresponding to different LUTs can be displayed, when the user selects the 4K HDR function simultaneously, the definition of the shot image is higher and more vivid, and therefore the styles or effects of the image shot by the electronic equipment can be enriched, and the shooting requirements of current user diversification are met.

In other embodiments, as shown in fig. 16 and 18, the photographing method may further include steps A1 to a17.

And A1, the electronic equipment receives a starting instruction of an AI model through an AI recommendation module.

Illustratively, the electronic device generates a startup instruction of the AI model in response to a user operation of the "AI movie hue" setting item. And then, the electronic equipment sends an AI model starting instruction to the AI recommendation module so that the AI recommendation module receives the AI model starting instruction.

And A2, the electronic equipment sends an instruction for acquiring the scene and the brightness of the preview image to the camera driving module through the AI recommendation module.

Illustratively, the AI recommendation module invokes the camera interface of the hardware abstraction layer to send instructions to the camera driver module to obtain the scene and brightness of the preview image.

And step A3, the electronic equipment returns the scene and brightness of the preview image through the camera driving module.

Illustratively, the camera driver module invokes the camera interface of the hardware abstraction layer to return the scene and brightness of the preview image to the AI recommendation module.

As shown in fig. 18, in some embodiments, when 4K HDR is in an unopened state, the photographing method provided in the embodiments of the present application includes:

And A4a, the electronic equipment identifies the scene and the brightness of the preview image through the AI recommendation module and matches the first LUT corresponding to the preview image.

In some embodiments, the AI recommendation module identifies the brightness of the preview image based on the first preset tag. The first preset label is used for representing the tone corresponding to different gray scale intervals. Illustratively, the first preset label includes black, shadows, middle tones, bright portions, and highlights. For example, the gradation interval corresponding to black is 0 to 33, the gradation interval corresponding to shading is 34 to 95, the gradation interval corresponding to intermediate tone is 96 to 169, the gradation interval corresponding to bright portion is 170 to 224, and the gradation interval corresponding to highlight is 225 to 255.

The above-described division of the gradation intervals corresponding to the respective hues is merely an example, and does not limit the embodiments of the present application.

In the embodiment of the present application, the highlight refers to an object whose preview image has white or near white. Such as lights, sun or highlights of slippery objects. The bright portion refers to a light color with details or texture of the preview image. Such as a light-colored garment, a wall, or two parts of a human face. Black refers to the preview image being black or near black. For example, an unlit portion.

For example, the AI recommendation module may identify the preview image according to the first preset label, and determine a tone corresponding to the preview image. For example, when the luminance value (may also be referred to as a gray value) of the preview image is 32, that is, the luminance value of the preview image is located in the gray scale interval 0 to 33, the AI recommendation module recognizes that the tone corresponding to the preview image is black. When the luminance value of the preview image is 175, that is, the luminance value of the preview image is located in the gray scale interval 170 to 224, the AI recommendation module recognizes that the corresponding image of the preview image is bright.

In some embodiments, the AI recommendation module may further identify the brightness of the preview image based on a second preset label. The second preset label is used for representing the exposure of the image. Illustratively, exposure refers to the ratio of black to high light. For example, when the black ratio is less than or equal to 5%, it means that the exposure amount of the preview image is high (i.e., overexposure). When the black ratio is greater than 5% and the highlight ratio is greater than or equal to 10%, it means that the exposure amount of the preview image is high (i.e., bright). When the black ratio is more than 5% and the highlight ratio is less than 10%, it means that the exposure amount of the preview image is normal (i.e., balanced).

For example, in combination with the above embodiment, when the AI recommendation module identifies that the preview image is highlighted, if the black ratio of the preview image is less than or equal to 5% on this basis, the AI recommendation module identifies that the preview image is overexposed, that is, that the preview image is highlighted and overexposed. If the black proportion of the preview image is greater than 5% and the highlight proportion is greater than or equal to 10%, the preview image is bright, that is, the AI recommendation module recognizes that the preview image is highlight and bright.

In some embodiments, the AI recommendation module may further identify a scene of the preview image according to a third preset tag. The third preset label is used for indicating scene information of the preview image. Exemplary scene information includes figures, delicacies, and the like. Illustratively, a portrait refers to a preview image including the five sense organs of a person; or the preview image may include more than 50% of the five sense organ portion of the total image. What the index finger is, is that the preview image includes food (e.g., coffee, bread, etc.).

For example, the AI recommendation module may process the preview image using image processing techniques and, if it is identified that the preview image includes the five sense organs of a person, indicate that the scene of the preview image is a portrait. If the preview image is recognized to include food, the scene of the preview image is shown as food.

In this embodiment of the present application, the AI recommendation module may identify the scene and brightness of the preview image in combination with the first preset tag, the second preset tag, and the third preset tag, so as to match the LUT corresponding to the preview image. Taking the example that the AI recommendation module recognizes that the tone of the preview image is highlight according to the first preset label, referring to the following table 2, the correspondence between the second preset label and the corresponding relation between the third preset label and the LUT is described.

TABLE 2

Note that, the correspondence between the second preset tag and the third preset tag shown in table 2 and the LUT template is only an example of the present application, and is not limited to the embodiments of the present application.

It should be understood that in this embodiment, the LUT template corresponding to the preview image matched by the AI recommendation module may include only one LUT, or may include two or more LUTs, which is not limited in this embodiment of the present application. In addition, when the 4K HDR is in an unopened state, the LUT template includes LUTs of LUT1, LUT2, LUT3, & gt, LUT 8; when 4K HDR is in an on state, the LUT templates include LUTs that are LUTs of LUT9, LUT10, LUT 11.

And step A5a, the electronic equipment sends the first LUT to the display screen through the AI recommendation module.

And step A6a, the electronic equipment displays the first LUT through a display screen.

As also shown in fig. 18, in other embodiments, when the 4K HDR is in an on state, the electronic device receives, through the HDR module, an activation instruction of the 4K HDR control, and sends, to the AI recommendation module, the activation instruction of the 4K HDR control. Correspondingly, after the AI recommendation module receives a starting instruction of the 4K HDR control, the shooting method provided by the embodiment of the application includes:

and step A4b, the electronic equipment identifies the scene and the brightness of the preview image through the AI recommendation module and matches a second LUT corresponding to the preview image.

And step A5b, the electronic equipment sends a second LUT to the display screen through the AI recommendation module.

And step A6b, the electronic equipment displays the second LUT through the display screen.

It should be noted that, for the illustration of step A4b, step A5b and step A6b, reference may be made to the illustration of step A4a, step A5a and step A6a in the above embodiments, and the details will not be described here.

With reference to any one of the foregoing embodiments, the photographing method provided in the embodiment of the present application further includes:

and A7, the electronic equipment receives a starting instruction of the LUT control through the LUT template module.

Illustratively, the electronic device generates the launch instruction in response to a user operation of the LUT control. And then, the electronic equipment sends a starting instruction of the LUT control to the LUT template module so that the LUT template module receives the starting instruction of the LUT control.

In some embodiments, when 4K HDR is in an unopened state, as shown in fig. 18, the photographing method provided in the embodiments of the present application includes:

Fig. 20 is a schematic flow chart of a shooting method according to an embodiment of the present application; the method can be applied to electronic equipment comprising a camera and a display screen, wherein the electronic equipment is preset with a plurality of first color lookup tables (LUTs); the method comprises the following steps:

S101, the electronic equipment responds to the operation of starting the camera by a user, and a shooting preview interface is displayed.

Wherein the shot preview interface includes a first preview image.

Taking an electronic device as a mobile phone as an example, in some embodiments, the electronic device starting a camera application to shoot in response to an operation of starting the camera by a user refers to the electronic device.

For example, in combination with the above embodiment, the shooting preview interface may be an interface of the camera in the video mode, an interface of the camera in the professional mode, or an interface of the camera in the movie mode. When the shooting preview interface is an interface of the camera in a video mode; or when the camera is at the interface in the professional mode, the first preview image is a preview image which is not processed by the LUT; when the shooting preview interface is an interface of the camera in the film mode, the first preview image is a preview image processed by a default LUT.

S102, the electronic device determines a first target LUT.

Wherein the first target LUT is one of a plurality of first LUTs.

In some embodiments, the user may select the corresponding LUT according to different shooting scenarios, i.e. the first target LUT is determined by the user himself. In other embodiments, the user may select an AI model, identify a preview image included in the preview interface prior to recording the video of the cell phone from the AI model, and match a LUT corresponding to the preview image, i.e., the first target LUT is determined by the AI model of the electronic device.

S103, the electronic equipment processes the first preview image according to the first target LUT so as to obtain a second preview image.

Wherein the preview effect of the first preview image is different from the preview effect of the second preview image.

In some embodiments, the electronic device may convert the gray value of each pixel in the first preview image according to the identification of the first target LUT, thereby obtaining the second preview image.

In this embodiment, the electronic device may process, on the photographing preview interface, the first preview image of the photographing preview interface according to the first target LUT determined by the electronic device, to obtain the second preview image; because the preview effects of the first preview image and the second preview image are different, in the video recording process, shooting effects or styles corresponding to different LUTs can be displayed, the effects of the recorded video images can be enriched, and the shooting requirements of current users are met.

Fig. 21 is a schematic flow chart of another photographing method according to an embodiment of the present application; the method comprises the following steps:

s201, the electronic equipment responds to the operation of starting the camera by a user, views a first image, and displays a third preview image processed by the first image on a shooting preview interface.

Taking an electronic device as a mobile phone as an example, in some embodiments, the electronic device starting a camera application to shoot in response to an operation of starting the camera by a user refers to the electronic device. Wherein the first image may also be referred to as a viewfinder image.

In some embodiments, the electronic device may process the first image using a third target LUT to obtain a third preview image. The third target LUT is an exemplary target LUT determined by the electronic device identifying image information of the first image using the AI model. In combination with the above embodiment, when the first target LUT is determined by using the AI model for the electronic device, the third target LUT may be the same as the first target LUT; the third preview image may be the same as the second preview image.

S202, the electronic equipment views a view to obtain a second image, and a fourth preview image processed by the second image is automatically displayed on a shooting preview interface.

Wherein the preview effect of the third preview image is different from the preview effect of the fourth preview image.

For example, when an image of the viewing interface of the electronic device changes (e.g., from a first image to a second image), the electronic device may re-view (e.g., the electronic device views the second image). Wherein the second image may also be referred to as a viewfinder image.

In some embodiments, the electronic device may process the first image using a fourth target LUT to obtain a fourth preview image. The fourth target LUT is an exemplary target LUT determined by the electronic device identifying the image information of the second image using the AI model. In combination with the above embodiment, when the first target LUT is determined by using the AI model for the electronic device, the fourth target LUT may be the same as the second target LUT, and the fourth preview image is a changed preview image.

As shown in fig. 13 and 14, the third preview image may be, for example, a preview image shown in (1) in fig. 13 and (1) in fig. 14; the fourth preview image may be, for example, a preview image shown in fig. 13 (2) and fig. 14 (2).

In addition, still as shown in conjunction with fig. 13 and 14, the third target LUT may be, for example, LUT2 shown in (1) in fig. 13 and (1) in fig. 14; the fourth target LUT may be, for example, LUT5 shown in (2) in fig. 13 and (2) in fig. 14.

In this embodiment, the electronic device may process different images obtained by framing to obtain different preview images corresponding to the different images, so that when the framing image of the electronic device changes, the preview images corresponding to the framing image can be automatically matched, so as to enrich the preview effect of the preview image, further enrich the effect of the recorded video image, and meet the shooting requirement of the current user.
