[0027] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The embodiment of the present application provides a shooting method and a device thereof, so as to achieve the purpose of shooting a target scene, so that the captured image has a correct white balance and a good image color effect, and can meet the user's requirements for image quality.

[0030] To facilitate understanding, the application scenarios and concepts involved in the embodiments of the present application are first introduced.

[0031] Multispectral technology: It is a spectrum detection technology based on the simultaneous acquisition of multiple optical spectrum bands (usually more than 3), and expanding to infrared and ultraviolet light based on visible light. By expanding the visible light band through imaging chips, the utilization rate of light energy can be improved, and more accurate color and color temperature recognition can be achieved.

[0032] Color temperature: It is a temperature measurement method, usually used in the fields of physics and astronomy. This concept is based on a fictitious black object that emits different colors of light when heated to different temperatures, and the object appears in different colors. Just like when a piece of iron is heated, it first turns red, then yellow, and finally turns white. The color temperature calibrated using this method is exactly the opposite of what the general public thinks of as "warm" and "cold". For example, people usually feel that red, orange and yellow are warmer, and white and blue are colder, but in fact red has the lowest color temperature, followed by orange, yellow, white and blue, and blue has the highest color temperature. When shooting with natural light, the color temperature of the light is different at different times, so the color of the image taken is also different. For example, when shooting under a clear blue sky, the image will be cold because the color temperature of the light is higher; if it is shot at dusk, the image will be warm because the color temperature of the light is lower. When shooting with artificial light, the color tones of the image taken will also be different due to different light source types.

[0033] Soft light: refers to a photography light that has soft light without obvious shadows, is suitable for reflecting the shape and color of objects, and gives people a soft and delicate feeling. Electronic equipment equipped with a soft light can turn on the soft light to provide real-time fill light when shooting.

[0034] In the related art, an electronic device is equipped with a soft light, which can only emit light of one color temperature. When a user uses the soft light of the electronic device to take pictures, he or she will encounter the following color temperature problems, resulting in the color effect of the captured image being relatively poor and failing to meet the user's requirements for image quality: for example, when shooting in a dark environment and turning on the soft light, the captured image cannot restore the original color temperature of the scene seen by the naked eye, but will be cooler (high color temperature) or warmer (low color temperature), and the white balance of the image will be incorrect; for another example, when shooting in a dark environment and turning on the soft light, if the main subject of the picture is a portrait, and there is a difference in color temperature between the foreground portrait and the background, the color of the captured image will be inconsistent and have a sense of cutout.

[0035] In the embodiment of the present application, the electronic device is equipped with a soft light, which has a multi-color temperature function, that is, it can emit light of multiple different color temperatures. When the user uses the electronic device to shoot the target scene, the color temperature of the target scene can be detected, and the fill light color temperature suitable for shooting the target scene can be determined according to the color temperature of the target scene. The soft light emits light according to the fill light color temperature and automatically emits light of a suitable color temperature to help the user correct the color temperature of the target scene so that the captured image has a correct white balance. In addition, the foreground and background in the target scene can be identified, the color temperature of the foreground and the color temperature of the background in the target scene can be detected, and the fill light color temperature suitable for shooting the foreground and background in the target scene can be determined according to the color temperature of the foreground and the color temperature of the background. The soft light emits light according to the fill light color temperature and automatically emits light of a suitable color temperature to help the user correct the color temperature difference between the foreground and the background in the target scene, so that the color temperature of the foreground and the background of the image captured in the target scene is coordinated and unified, without a sense of clipping, and the image color effect is good, which can meet the user's requirements for image quality.

[0036] Next, in conjunction with the accompanying drawings, the shooting method provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0037] It should be noted that the shooting method provided in the embodiment of the present application is applicable to electronic devices. In practical applications, the electronic devices may include: mobile terminals such as smart phones, tablet computers, personal digital assistants, etc., and the embodiment of the present application does not limit this.

[0038] Figure 1 This is one of the flow charts of a shooting method provided in an embodiment of the present application, such as Figure 1 As shown, the method may include the following steps: step 101, step 102 and step 103;

[0039] In step 101, the color temperature of the target scene is detected to obtain a color temperature detection result.

[0040] In the embodiment of the present application, the target scene is the scene in which the electronic device is currently located. The target scene can be any scene, for example, a scene in a dark environment, a scene in a bright environment, etc.

[0041] In the embodiment of the present application, when the user wants to shoot the target scene, the color temperature detection of the target scene can be triggered by operating the color temperature detection control of the electronic device. Alternatively, the color temperature detection of the target scene can be automatically triggered when the camera of the electronic device is detected to be turned on.

[0042] In an embodiment of the present application, the electronic device may be configured with hardware for color temperature detection, for example, a multi-spectral color temperature sensor, and the multi-spectral color temperature sensor may be used to perform color temperature detection on a target scene.

[0043] In the embodiments of the present application, different multispectral color temperature sensors are considered to have different detection accuracy. For example, some multispectral color temperature sensors can detect color temperature scenes, wherein the color temperature scenes may include: warm light (tungsten lamp), warm white light (daylight), white with yellow (sunrise), completely white light (noon daylight), completely white light with a slight blue (daylight), white light with a bluish tint (clear daylight), light with a bluish tint (sunny daylight), and blue light (white light on a cloudy day, blue sky) and other light scenes. For another example, other multispectral color temperature sensors can detect scene color temperature values, wherein the scene color temperature values ​​may include: color temperature values ​​below 3000K, 3000K-3999K, 4000K-4999K, 5000K-5999K, 6000K-6499K, 6500K-6999K, 7000K-7999K, and above 8000K.

[0044] Among them, the color temperature scene and the scene color temperature value may have a mapping relationship as shown in Table 1.

[0045] Color temperature scene The color temperature of the scene Warm light (tungsten lamp) Below 3000k Warm white light (daylight) 3000k-3999k White with yellow (sunrise) 4000k-4999k Completely white light (midday sunlight) 5000k-5999k Completely white light with a slight bluish tint (daylight) 6000k-6499k White light tends to be bluish (sunny daylight) 6500k-6999k Light is bluish (sunny daylight) 7000k-7999k Blue light (white light on cloudy days, blue sky) 8000k and above

[0046] Table 1

[0047] In the embodiments of the present application, for multispectral color temperature sensors with different detection accuracy, the representation forms of the color temperature detection results of the target scene are also different. For example, for a multispectral color temperature sensor that detects color temperature scenes, the color temperature detection results of the target scene include: the color temperature scene to which the target scene belongs. For a multispectral color temperature sensor that detects the color temperature value of a scene, the color temperature detection results of the target scene include: the color temperature value of the target scene. In addition, for a multispectral color temperature sensor that detects color temperature scenes, the color temperature detection results of the target scene can also be converted from the color temperature scene to which the target scene belongs to the color temperature value of the target scene through the mapping relationship shown in Table 1 above.

[0048] In step 102, a correction color temperature value of the soft light is determined according to the color temperature detection result, wherein the correction color temperature value is used to correct the color temperature of the target scene during shooting.

[0049] In the embodiment of the present application, the corrected color temperature value is a color temperature value of a fill light color temperature suitable for shooting in the target scene. When using an electronic device to shoot the target scene, the soft light emits light according to the above fill light color temperature. Under the above color temperature light emitted by the soft light, the image of the target scene captured has a better effect.

[0050] In the embodiment of the present application, there is a mapping relationship between the color temperature detection result and the corrected color temperature value, and the corrected color temperature value of the soft light in the current target scene can be determined based on the mapping relationship.

[0051] In some embodiments, the color temperature detection result includes a color temperature scene, and different color temperature scenes correspond to different corrected color temperature values. That is, there is a mapping relationship between the color temperature scene and the corrected color temperature value.

[0052] For example, the following Table 2 shows the mapping relationship between the color temperature scene and the corrected color temperature value.

[0053] Color temperature scene Corrected color temperature value corresponding to soft light Warm light (tungsten lamp) 9000k Warm white light (daylight) 8000k White with yellow (sunrise) 7000k Completely white light (midday sunlight) / Completely white light with a slight bluish tint (daylight) 4000k White light tends to be bluish (sunny daylight) 3500k Light is bluish (sunny daylight) 3000k Blue light (white light on cloudy days, blue sky) 2000k

[0054] Table 2

[0055] In the embodiment of the present application, when the color temperature detection result includes the color temperature scene to which the target scene belongs, the corrected color temperature value of the soft light under the target scene can be determined according to the mapping relationship shown in Table 2.

[0056] In some embodiments, the color temperature detection result includes a scene color temperature value, and scene color temperature values ​​in different intervals correspond to different corrected color temperature values, that is, there is a mapping relationship between the scene color temperature value and the corrected color temperature value.

[0057] For example, the following Table 3 shows the mapping relationship between the scene color temperature value and the correction color temperature value.

[0058]

[0059]

[0060] Table 3

[0061] In the embodiment of the present application, when the color temperature detection result includes the color temperature value of the target scene, the corrected color temperature value of the soft light in the target scene can be determined according to the mapping relationship shown in Table 3.

[0062] According to Table 2 and Table 3, the mapping relationship between the color temperature scene, the scene color temperature value and the correction color temperature value shown in Table 4 below can be obtained.

[0063] Color temperature scene The color temperature of the scene Corrected color temperature value corresponding to soft light Warm light (tungsten lamp) Below 3000k 9000k Warm white light (daylight) 3000k-3999k 8000k White with yellow (sunrise) 4000k-4999k 7000k Completely white light (midday sunlight) 5000k-5999k / Completely white light with a slight bluish tint (daylight) 6000k-6499k 4000k White light tends to be bluish (sunny daylight) 6500k-6999k 3500k Light is bluish (sunny daylight) 7000k-7999k 3000k Blue light (white light on cloudy days, blue sky) 8000k and above 2000k

[0064] Table 4

[0065] It can be seen that in the embodiments of the present application, various types of multi-spectral color temperature sensors can be supported. For different types of multi-spectral color temperature sensors, a mapping relationship between different types of color temperature detection results and the corrected color temperature values ​​of the soft light is preset, which can be applicable to electronic devices with different configurations and has a wide range of application scenarios.

[0066] In step 103, during shooting, the soft light is controlled to emit light according to the calibrated color temperature value, and the first image is captured.

[0067] In the embodiment of the present application, the soft light configured for the electronic device can emit lights of various color temperatures. According to different scenes, it can emit lights of color temperatures matching different scenes to achieve differentiated fill light for different scenes, and can adapt to various shooting scenes.

[0068] In an embodiment of the present application, the electronic device may be configured with a front soft light and a rear soft light, wherein the front soft light is arranged on the front side of the electronic device, and the rear soft light is arranged on the back side of the electronic device.

[0069] In the embodiment of the present application, it is possible to select which soft light to turn on for fill light according to the camera used for shooting. For example, when shooting with the front camera of the electronic device, the front soft light is controlled to emit light according to the calibrated color temperature value. When shooting with the rear camera of the electronic device, the rear soft light is controlled to emit light according to the calibrated color temperature value.

[0070] In the embodiment of the present application, after receiving the calibrated color temperature value, the soft light can be converted into current demand and automatically emit light of appropriate color temperature to help the user calibrate the color temperature of the target scene.

[0071] In the embodiment of the present application, the soft light emits light according to the corrected color temperature value, emitting light of appropriate color temperature so that the color temperature of the target scene is corrected. At this time, the camera of the electronic device shoots the target scene to obtain a first image, which has a correct white balance.

[0072] As can be seen from the above embodiments, in this embodiment, the color temperature of the target scene is detected to obtain a color temperature detection result; based on the color temperature detection result, the corrected color temperature value of the soft light is determined; when shooting, the soft light is controlled to emit light according to the corrected color temperature value to obtain a first image. It can be seen that in the embodiment of the present application, before using an electronic device to shoot the target scene, the color temperature of the target scene can be detected first, and the fill light color temperature (i.e., the corrected color temperature value) suitable for shooting in the target scene can be determined based on the color temperature of the target scene. The soft light of the electronic device converts the determined fill light color temperature into current demand, emits light of a color temperature suitable for shooting, and helps the user to automatically correct the color temperature of the target scene, so that the image captured in the target scene has a correct white balance, and the image color effect is better, which can meet the user's requirements for image quality.

[0073] Figure 2 This is a second flow chart of a shooting method provided in an embodiment of the present application, such as Figure 2 As shown, the method may include the following steps: step 201, step 202 and step 203;

[0074] In step 201, color temperature detection is performed on both the foreground object and the background object in the target scene to obtain a scene color temperature value corresponding to the foreground object and a scene color temperature value corresponding to the background object.

[0075] Considering that if the color temperature of the foreground object in the target scene is significantly different from that of the background object, the captured image will have inconsistent colors and a cutout feel, in response to the above problem, in an embodiment of the present application, the foreground object and the background object in the target scene can be identified, and then the color temperature of the foreground object and the background object can be detected respectively. According to the scene color temperature value corresponding to the foreground object and the scene color temperature value corresponding to the background object, the color temperature difference between the foreground object and the background object is determined. If the color temperature difference is large, a correction color temperature value is determined that can be used to balance the color temperature difference between the foreground object and the background object.

[0076] In an example, Figure 3 As shown, the target scene includes a foreground object 31 and a background object 32, and the scene color temperature value corresponding to the foreground object 31 and the scene color temperature value corresponding to the background object 32 are detected respectively.

[0077] In step 202, the intermediate color temperature value between the scene color temperature value corresponding to the foreground object and the scene color temperature value corresponding to the background object is calculated; and the corrected color temperature value of the soft light is determined according to the intermediate color temperature value.

[0078] In an embodiment of the present application, if the difference between the scene color temperature value of the foreground object and the scene color temperature value of the background object is greater than a certain threshold (for example, 2000K), it is considered that the color temperature difference between the foreground object and the background object is large. At this time, the intermediate color temperature value of the foreground object and the background object is calculated as the color temperature value of the target scene. Then, based on the mapping relationship between the color temperature value of the scene and the corrected color temperature value, the corrected color temperature value of the soft light in the target scene is determined.

[0079] In step 203, during shooting, the soft light is controlled to emit light according to the calibrated color temperature value, and the first image is captured.

[0080] In the embodiment of the present application, the soft light emits light according to the corrected color temperature value and emits light of appropriate color temperature, so that the color temperature difference between the foreground object and the background object in the target scene is corrected. At this time, the camera of the electronic device shoots the target scene to obtain a first image. The first image has a correct white balance, and the color temperature of the image of the foreground object and the image of the background object in the image are coordinated and unified, without a sense of clipping.

[0081] As can be seen from the above embodiments, in this embodiment, color temperature detection is performed on both the foreground object and the background object in the target scene to obtain the scene color temperature value corresponding to the foreground object and the scene color temperature value corresponding to the background object; the intermediate color temperature value of the scene color temperature value corresponding to the foreground object and the scene color temperature value corresponding to the background object is calculated; based on the intermediate color temperature value, the corrected color temperature value of the soft light is determined, wherein the corrected color temperature value is used to correct the color temperature of the target scene during shooting; during shooting, the soft light is controlled to emit light according to the corrected color temperature value to capture a first image. It can be seen that in the embodiment of the present application, before using the electronic device to shoot the target scene, the foreground and background in the target scene can be identified first, the color temperature of the foreground and the background can be detected, and the fill light color temperature (i.e., the corrected color temperature value) suitable for shooting the foreground and background in the target scene can be determined according to the color temperature of the foreground and the background. The soft light of the electronic device converts the determined fill light color temperature into current demand, and emits light of a color temperature suitable for shooting, so as to help the user automatically correct the color temperature difference between the foreground and the background in the target scene, so that the color temperature of the foreground and the background of the image captured in the target scene is coordinated and unified, without a sense of clipping, and the image color effect is better, which can meet the user's requirements for image quality.

[0082] In another embodiment provided in the present application, the provided shooting method can also be Figure 1 or Figure 2 On the basis of the embodiment shown, the following steps are added: step 401, step 402, step 403 and step 404;

[0083] In step 401, N second images of different color temperature styles are generated based on the first image, where N is a positive integer.

[0084] In an embodiment of the present application, the color temperature styles may include: cold color temperature 1, cold color temperature 2, cold color temperature 3, warm color temperature 3, warm color temperature 2 and warm color temperature 1, wherein the image color temperature value corresponding to cold color temperature 1 is about 3000K, the image color temperature value corresponding to cold color temperature 2 is about 4000K, the image color temperature value corresponding to cold color temperature 3 is about 5000K, the image color temperature value corresponding to warm color temperature 3 is about 6000K, the image color temperature value corresponding to warm color temperature 2 is about 7000K, and the image color temperature value corresponding to warm color temperature 1 is about 8000K.

[0085] In one example, if the color temperature style of the first image is cold color temperature 1, five images with different color temperature styles from cold to warm can be generated based on the first image, and the corresponding color temperature values ​​cover 3000k-5000k, for example, Figure 4 As shown, the first image is Figure 1, then five other color temperature style images are generated, namely: image 2 with cold color temperature 2 style, image 3 with cold color temperature 3 style, image 4 with warm color temperature 3 style, image 5 with warm color temperature 2 style, and image 6 with warm color temperature 1 style.

[0086] In an embodiment of the present application, the first image and N second images can be stored in an album. That is to say, for the original image taken by the user, multiple images with different color temperatures from cold to warm can be automatically generated in the album based on the original image for the user to choose from, so as to meet the user's diverse needs for image color temperature effects.

[0087] In step 402, a first input is received, and in response to the first input, a first editing area and a second editing area are displayed, wherein a first image is displayed in the first editing area, and a third image is displayed in the second editing area, and the third image is an image of the N second images having a color temperature style opposite to that of the first image.

[0088] In the embodiment of the present application, if the user is not satisfied with the color temperature effect of the first image or the automatically generated second image, the color temperature effect of the above image can be edited and adjusted.

[0089] In the embodiment of the present application, when the first input is received, two editing areas can be displayed simultaneously, and the user can customize the color temperature of the image displayed in each editing area.

[0090] In the embodiment of the present application, the first input may be: a click input of the user on the album, or a voice command input by the user, or a specific gesture input by the user, wherein the specific gesture may be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture; the click input may be a single-click input, a double-click input, or any number of click inputs, etc., and may also be a long-press input or a short-press input. The specific input may be determined according to actual use requirements, and the embodiment of the present application does not limit this.

[0091] In an embodiment of the present application, when displaying the first editing area and the second editing area, the first editing area and the second editing area can be displayed side by side, for example, the first editing area is displayed on the left side of the electronic device screen, and the second editing area is displayed on the right side; or, the first editing area and the second editing area can be displayed vertically, for example, the first editing area is displayed in the upper half of the electronic device screen, and the second editing area is displayed in the lower half.

[0092] In an embodiment of the present application, the captured first image (that is, the image with the color temperature value closest to that visible to the naked eye) can be automatically placed in the first editing area, and the generated image with the opposite color temperature style to the first image can be automatically placed in the second editing area.

[0093] In step 403, a second input to the first editing area is received, and in response to the second input, a color temperature adjustment control is displayed.

[0094] In the embodiment of the present application, the second input may be a click input of the user on the first editing area, or a voice command input by the user, or a specific gesture input by the user, etc.

[0095] In the embodiment of the present application, the color temperature adjustment control may be a wheel-type control or a slide bar-type control, wherein when the color temperature adjustment control is a wheel-type control, the wheel-type control may correspond to multiple scales, each scale corresponds to an image color temperature value, and the user may adjust the color temperature of the image by sliding the wheel-type control to a specified scale. When the color temperature adjustment control is a slide bar-type control, the slide bar-type control may correspond to multiple scales, each scale corresponds to an image color temperature value, and the user may adjust the color temperature of the image by sliding the slide bar-type control left and right to a specified scale.

[0096] In one example, combining Figure 4 In the example shown, after clicking on the album, Figure 5 As shown, a first editing area 51, a second editing area 52, an image selection area 53 and a wheel-type control 54 are displayed on the electronic device 50, wherein image 1 is displayed in the first editing area 51, and image 6 with a color temperature style opposite to that of image 1 is displayed in the second editing area 52, wherein multiple images of other color temperature styles generated based on image 1 are displayed in the image selection area 53.

[0097] In another example, still combined with Figure 4 In the example shown, after clicking on the album, Figure 6 As shown, a first editing area 61, a second editing area 62, an image selection area 63 and a wheel-type control 64 are displayed on the electronic device 60, wherein image 1 is displayed in the first editing area 61, image 6 with a color temperature style opposite to that of image 1 is displayed in the second editing area 62, and multiple images of other color temperature styles generated based on image 1 are displayed in the image selection area 63.

[0098] In step 404, a third input to the color temperature adjustment control is received, and in response to the third input, the image color temperature is adjusted for at least the first image in the first editing area.

[0099] In some embodiments, the image color temperature may be adjusted only for the image in the first editing area. Accordingly, the above step 404 includes the following steps:

[0100] The image color temperature of the first image in the first editing area is adjusted according to the color temperature value of the first image selected by the third input, and the color temperature of the second image in the second editing area does not change.

[0101] In some embodiments, the image color temperature can be adjusted for the images in the two editing areas at the same time. Accordingly, the above step 404 includes the following steps: step 4041 and step 4042;

[0102] In step 4041, the image color temperature of the first image in the first editing area is adjusted according to the first image color temperature value selected by the third input.

[0103] In step 4042, the image color temperature of the third image in the second editing area is adjusted according to the second image color temperature value, wherein the second image color temperature value is an image color temperature value having a color temperature value opposite to the first image color temperature value.

[0104] In the embodiment of the present application, when the color temperature of the image in the first editing area changes, the color temperature of the image in the second editing area changes in the opposite direction, so as to adjust the color temperature of the two images at the same time.

[0105] In an embodiment of the present application, different types of third inputs can be set, corresponding to different numbers of image adjustments. For example, when the third input is a single-finger sliding input, the image color temperature is adjusted only for the image in one editing area; when the third input is a two-finger sliding input, the image color temperature is adjusted for the images in two editing areas at the same time, but the directions of the color temperature adjustments are opposite.

[0106] In the embodiment of the present application, after completing the color temperature adjustment of the image, click the Save button. At this time, the two images adjusted in the positive direction and the reverse direction can be synthesized and saved separately, and the user obtains two images with special effects.

[0107] It can be seen that in the embodiments of the present application, in terms of image post-editing, a new image editing interaction method is proposed, which can support users to adjust the color temperature with a wheel control or a slider control, support one-click dual-image color temperature adjustment, and complete two opposite special color temperature style adjustments with one click, thereby meeting the user's needs for customizing special effects in more scenarios.

[0108] In another embodiment provided by the present application, in addition to adjusting the color temperature of the captured original image and an image with a color temperature style opposite to the original image, it is also possible to support color temperature adjustment of other images to meet the editing needs of the user. Accordingly, the provided shooting method can also add the following steps on the basis of the previous embodiment: step 405 and step 406;

[0109] In step 405, a fourth input of the first editing area and a fourth image is received, wherein the fourth image is an image other than the third image among the N second images.

[0110] In the embodiment of the present application, the fourth input may be a drag input, for example, dragging the fourth image in the album to the first editing area.

[0111] In step 406, in response to the fourth input, the image in the first editing area is replaced with a fourth image, and the image in the second editing area is replaced with a fifth image, wherein the fifth image is an image of the N second images having a color temperature style opposite to that of the fourth image.

[0112] In one example, combining Figure 5 The example shown is Figure 7 As shown, the user can click on "Image 2" in the image selection area 53 and drag "Image 2" to the first editing area 51, and the image displayed in the first editing area 51 becomes "Image 2". At the same time, the image displayed in the second editing area 52 becomes "Image 5", where Image 2 has opposite color temperature styles to Image 5.

[0113] In another example, combining Figure 6 The example shown is Figure 8 As shown, the user can click on "Image 2" in the image selection area 63 and drag "Image 2" to the first editing area 61. The image displayed in the first editing area 61 becomes "Image 2". At the same time, the image displayed in the second editing area 62 becomes "Image 5", where Image 2 has opposite color temperature styles to Image 5.

[0114] In an embodiment of the present application, after replacing the image in the first editing area with the fourth image, and replacing the image in the second editing area with the fifth image, the user can perform a wheel-type / slide-bar type adjustment of the warm or cold color temperature of the image in one editing area, while the image in the other editing area will undergo an opposite color temperature change.

[0115] It can be seen that in the embodiment of the present application, the user can be supported to adjust the color temperature of images other than the original image to meet the user's editing needs.
