Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a color selection method and electronic equipment. Background Art

[0002] Image color extraction is widely used in electronics. Related technologies can perform real-time color extraction based on the coordinates of an image and a region within it. For example, a desktop calendar on a personal computer (PC) can be displayed with the background color of the calendar as the desktop wallpaper.

[0003] However, for some images that will be colored multiple times, such as desktop wallpapers, due to the changes in the color picking area, it is necessary to use a color picking algorithm to perform multi-position color picking operations on the image to obtain the color of the color picking area. This method consumes a lot of computational resources. Summary of the Invention

[0004] The embodiments of the present application provide a color picking method and an electronic device, which reduce the computing power of a processor while ensuring the color picking effect.

[0005] In the first aspect, the embodiments of the present application provide a color selection method that can be applied to electronic devices. The electronic device here can refer to the electronic device itself, or it can refer to a processor, module, chip, or chip system that implements the method in the electronic device. The following is an example of an electronic device, and the method includes the following steps:

[0006] Obtain position information of a color picking area in a first image; determine the color of the color picking area based on the position information of the color picking area and the color storage information of the first image, wherein the color storage information of the first image includes: position information of multiple color storage blocks of the first image and color information corresponding to the multiple color storage blocks.

[0007] In this application, the electronic device pre-acquires the color storage information of the first image, and determines the color of the color picking area based on the color storage information and the position information of the color picking area. This method does not repeatedly use the color picking algorithm to calculate the color of the color picking area, which can reduce the computing consumption of the processor and ensure the color picking effect.

[0008] In one possible design, the electronic device determines the proportion of each color storage block in the color picking area and the color information corresponding to each color storage block in the color picking area based on the position information of the color picking area and the color storage information of the first image; and performs color block fusion based on the proportion of each color storage block in the color picking area and the color information corresponding to each color storage block in the color picking area to determine the color of the color picking area.

[0009] This method does not repeatedly use the color picking algorithm to calculate the color of the color picking area, which can reduce the computing consumption of the processor, ensure the color picking effect, and clearly define the color of the color picking area.

[0010] In one possible design, color block fusion includes one of the following methods: if the color picking area includes a first proportion color block, each color storage block in the color picking area is weighted averaged according to the proportion; or, if the color picking area includes multiple second proportion color blocks, after adjusting the weights of the color storage blocks corresponding to the multiple second proportion color blocks, each color storage block in the color picking area is weighted averaged; or, if the color picking area includes multiple third proportion color blocks, each color storage block in the color picking area is weighted averaged according to the proportion and then the color purity is reduced; wherein, the first proportion color block is a color storage block with an area proportion greater than 80% in the color picking area; multiple second proportion color blocks are color storage blocks with the same category of color, and the total area proportion of the multiple second proportion color blocks in the color picking area is greater than 80%; multiple third proportion color blocks are color storage blocks with the same category of color, and the total area proportion of the multiple third proportion color blocks in the color picking area is not greater than 80%.

[0011] Using the above method to perform color block fusion can reduce the computing consumption of the processor and ensure the color picking effect.

[0012] In one possible design, after the electronic device divides the first image into multiple grid areas of the same size, it samples the multiple grid areas separately to obtain the intermediate color values ​​in the multiple grid areas respectively; according to the distance values ​​between the intermediate color values ​​in the multiple grid areas, the multiple grid areas are connected to obtain multiple color storage areas, wherein the color storage areas correspond to the color storage blocks; a color sampling algorithm is used to sample colors from the multiple color storage areas separately to obtain multiple color storage blocks, and color storage information of the first image is obtained; and the color storage information of the first image is stored.

[0013] Acquiring the stored color information of the first image based on the above method can reduce the computational consumption of the processor and ensure the color extraction effect.

[0014] In one possible design, the electronic device connects multiple grid areas based on the distance values ​​between the intermediate color values ​​in the multiple grid areas to obtain multiple color storage areas, and determines that a first condition is satisfied; wherein the first condition includes one or more of the following: the area of ​​the first image is greater than or equal to a first area threshold; or, the color picking areas are discretely distributed; or, the area of ​​the color picking areas is greater than or equal to a second area threshold, and the second area threshold is related to the area of ​​the first image.

[0015] Based on this, the electronic device can clearly determine the timing for performing connectivity processing on the grid area, and further reduce the computational consumption of the processor.

[0016] In a possible design, the electronic device divides the first image into multiple grid areas of the same size, samples the multiple grid areas respectively, obtains color storage information of the first image, and stores the color storage information of the first image.

[0017] By acquiring the color storage information of the first image in the above manner, the color extraction effect can be guaranteed.

[0018] In one possible design, the electronic device responds to a color picking area selection operation; or receives a system notification.

[0019] Based on this, the electronic device can obtain the position information of the color picking area.

[0020] In one possible design, the color picking area is static or changes dynamically.

[0021] In one possible design, the location information includes one of the following:

[0022] The geographic coordinates of all endpoints, the coordinates of the center point and the length of the sides, and the geographic coordinates of one endpoint and the length of the sides.

[0023] In one possible design, the color information is indicated by one of the following parameters: RGB (red (R), green (G), blue (B)) value.

[0024] In a second aspect, embodiments of the present application provide an electronic device comprising one or more processors and a memory; the one or more processors are coupled to the memory, and the one or more processors are configured to read a computer program stored in the memory to execute any of the methods provided in any of the above aspects.

Optionally, the chip may further include components such as a memory, a communication interface, and a power supply module.

[0086] It is understandable that Figure 1 The components shown do not constitute a specific limitation on the electronic device. The electronic device in the embodiment of the present invention may include Figure 1 More or fewer components in . In addition, Figure 1 The combination / connection relationship between the components can also be adjusted and modified.

[0087] Optionally, the software system of the electronic device 100 can adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The layered architecture divides the software into several layers, each with a clear role and division of labor. The layers communicate with each other through software interfaces. For example, Figure 2 As shown in the figure, the software architecture can be divided into four layers, from top to bottom: application layer, application framework layer (framework, FWK), runtime and system library, and (Linux) kernel layer.

[0088] The application layer is the top layer of the operating system, including native applications of the operating system, such as calendar, Bluetooth, music, video, mailbox, etc., and may also include third-party applications. The application involved in the embodiment of the present application is referred to as application (APP), which is a software program that can realize one or more specific functions. Typically, multiple applications can be installed in an electronic device. The applications mentioned below can be system applications that are installed on the electronic device when it leaves the factory, or they can be third-party applications that the user downloads from the Internet or obtains from other electronic devices while using the electronic device.

[0089] Of course, developers can write applications and install them into this layer. In one possible implementation, applications can be developed using the Java language by calling the application programming interface (API) provided by the application framework layer. Developers can use the application framework to interact with the underlying layer of the operating system (such as the kernel layer) and develop their own applications.

[0090] The application framework layer provides the application API and programming framework. It includes predefined functions and can include a window manager, content provider, view system, resource manager, and notification manager.

[0091] The window manager is used to manage window programs. The window manager can obtain the display size, determine whether there is a status bar, lock the display (or screen), capture the display, etc.

[0092] Content providers are used to store and retrieve data and make it accessible to applications. The data may include files (such as documents, videos, images, audio), text, and other information.

[0093] The view system includes visual controls, such as those that display text, images, and documents. The view system is used to build applications. The interface in a display window can be composed of one or more views.

[0094] The runtime includes the core library and the virtual machine. The runtime is responsible for the scheduling and management of the system.

[0095] The system's core library consists of two parts: one containing the Java language's callable functions and the other the system's core library. The application layer and application framework layer run within a virtual machine. For example, in Java, the virtual machine executes Java files from the application and framework layers as binary files. The virtual machine manages object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0096] The system library can include multiple functional modules. For example: surface manager, media library, 3D graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), image processing library, etc. The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications. The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.564, MP3, AAC, AMR, JPG, PNG, etc. The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis and layer processing, etc. The 2D graphics engine is a drawing engine for 2D drawing.

[0097] The kernel layer provides the operating system's core system services, such as security, memory management, process management, network protocol stacks, and driver models. These services are all implemented at the kernel layer. The kernel layer also serves as an abstraction layer between the hardware and software stacks. This layer contains many drivers related to electronic devices, including the following: keyboard drivers for input devices; audio drivers; Wi-Fi drivers; Bluetooth drivers; and display drivers.

[0098] It should be understood that the functional services described above are only examples. In actual applications, electronic devices can also be divided into more or fewer functional services according to other factors, or the functions of each service can be divided in other ways, or the functional services can be not divided but work as a whole.

[0099] For images that may be picked up multiple times in electronic devices (such as desktop wallpapers, mobile phone screensavers, etc.), a color picking algorithm is used to perform multiple operations on the colors of the picked up areas. This consumes a lot of computation and is unbearable for electronic devices with low computing performance.

[0100] Based on this, this application provides a color picking method that reduces the computational consumption of the processor while ensuring the color picking effect. Figure 1 The electronic device shown in FIG. 1 may have a software structure as shown in FIG. Figure 2 As shown below. Figure 3 The method provided in this application is described in detail. Execute as follows:

[0101] In step 301 , the electronic device obtains position information of a color extraction area in a first image.

[0102] The first image is an image that may be used for multiple color extractions, such as a computer desktop wallpaper, a mobile phone screen saver, a web page cover, etc., which is not specifically limited here. The first image may be a single image or multiple images, and the number and size of the first images are not specifically limited here.

[0103] In one possible implementation, the electronic device can obtain the position information of the color picking area in the first image by calculating the position of the color picking area in response to the color picking area selection operation. The color picking area selection operation can be a user touch operation. For example, the color picking area is a folder, and the user adjusts the size of the folder by sliding the phone screen with his finger to drag the APP icon to the folder. Figure 4A As shown, or as Figure 4B As shown, the user slides the phone screen with his finger to drag the folder location, or, as shown Figure 4C As shown, the user drags the folder position by sliding the finger on the phone screen, and drags the APP icon to the folder to adjust the folder size. In addition, the color picking area selection operation can also be a user voice operation, such as controlling the APP icon on the phone screen to move to a certain folder by voice. This is only an example and not limited to specific examples. In addition, when the electronic device is a laptop, the color picking area selection operation can be understood as dragging a window, such as Figure 5 In the example, the calendar window at different locations on the desktop can be understood as different color picking areas, such as color picking area 1 on the right side of the desktop and color picking area 2 on the lower left side of the desktop. This is only an example and not a limitation. The above color picking areas can be understood as dynamically changing.

[0104] In another possible implementation, the electronic device may receive a system notification to obtain the location information of the color picking area in the first image. For example, the position of a window in a laptop computer (the navigation window below the desktop, such as the taskbar / program bar) is fixed (that is, a static color picking area). The system calculates the location information of the window and sends it directly to the electronic device.

[0105] It should be noted that this application does not specifically limit the shape, size and number of the color picking areas. For example, the color picking area is rectangular, the color picking area is elliptical, and the color picking area is irregular, which are not specifically limited here.

[0106] For example, the location information of the color picking area in the first image can be the geographic coordinates of all endpoints of the color picking area, the coordinates of the center point of the color picking area and the side length, or the geographic coordinates of one endpoint of the color picking area and the side length. How to represent the location information of the color picking area is not specifically limited herein.

[0107] In step 302 , the electronic device determines the color of the color picking area according to the position information of the color picking area and the color storage information of the first image.

[0108] The color storage information of the first image includes: position information of a plurality of color storage blocks of the first image and color information corresponding to the plurality of color storage blocks.

[0109] In a possible implementation, the electronic device obtains the color storage information of the first image in advance by referring to the following steps, and stores the color storage information of the first image, and performs the following:

[0110] In step S1 , the electronic device divides a first image into a plurality of grid areas of the same size, samples the plurality of grid areas respectively, and obtains intermediate color values ​​in the plurality of grid areas respectively.

[0111] For example, if the first image is 640*480 in size, the grid area can be 50*50, 30*30, or the like. The size of the grid area is not specifically limited herein. If the first image includes multiple colors, more grid areas can be provided in the first image, and the grid area sizes can be smaller. If the first image includes a relatively single color, fewer grid areas can be provided in the first image, and the grid area sizes can be larger. The specific method for setting the grid area sizes can be determined based on the size of the first image, the color distribution within the first image, and the computing power of the electronic device. For example, if the first image is 1920*1080 in size, the colors within the first image are relatively scattered and include multiple colors, and the electronic device has relatively strong computing power (e.g., a graphics processing unit (GPU) with 8 cores), the first image can be divided into more grid areas. For example, if the first image is 1920*1080 in size, the colors within the first image are relatively single, and the electronic device has relatively weak computing power (e.g., a GPU with 2 cores), the first image can be divided into fewer grid areas. This is merely an example description and does not specifically limit how to divide the first image into grid areas.

[0112] Exemplarily, the electronic device may use the color value (e.g., RGB value) of the middle pixel in each grid area as the middle color value of each grid area. For example, if the RGB value of the middle pixel in grid area 1 is (25, 25, 25), then (25, 25, 25) is the middle color value. The electronic device may also use the average color value of all pixels in each grid area as the middle color value of each grid area. For example, if grid area 2 includes three pixels, and the RGB values ​​of each pixel are (25, 25, 25), (50, 50, 50), and (75, 75, 75), respectively, and the average color value of the three pixels in grid area 2 is (50, 50, 50), then (50, 50, 50) is the middle color value.

[0113] In addition, the present application does not specifically limit the number of first images. It can be one picture or multiple pictures. The number of first images is not specifically limited here.

[0114] In step S2, the electronic device connects the multiple grid areas according to the distance values ​​between the intermediate color values ​​in the multiple grid areas to obtain multiple color storage areas, wherein the color storage areas correspond to the color storage blocks.

[0115] For example, if the distance between the intermediate color values ​​in multiple grid regions is small, the grid regions can be connected to form a single region. For example, if the RGB values ​​of grid region 1 are (25, 25, 25), the RGB values ​​of grid region 2 are (25, 24, 25), the RGB values ​​of grid region 3 are (24, 25, 25), and the RGB values ​​of grid region 4 are (25, 25, 24), then the distances between grid region 1, grid region 2, grid region 3, and grid region 4 can be understood to be small, and grid region 1, grid region 2, grid region 3, and grid region 4 can be connected to form a single color storage region.

[0116] For example, if the difference in RGB values ​​between adjacent grid regions is small (e.g., an R difference of 0.5, a G difference of 0.5, a B difference of 0.5, etc., which is only an example and not a limitation), the electronic device may connect the grid regions into one region. If the difference in RGB values ​​between adjacent grid regions is large (e.g., an R difference of 10, a G difference of 10, a B difference of 15, etc., which is only an example and not a limitation), the electronic device does not connect the grid regions into one region. Alternatively, the electronic device may convert the RGB values ​​of each grid region into Lab values ​​(where L represents brightness; a positive value represents red, a negative value represents green; b positive value represents yellow, a negative value represents blue). If the Euclidean distance between adjacent grid regions is less than a distance threshold (which can be flexibly set based on the needs of the specific application and is not specifically limited here, for example, in the color selection scenario, the distance threshold is 50), the grid regions may be connected into one region. This is only an example and does not specifically limit how to connect the grid regions.

[0117] In step S3, the electronic device uses a color picking algorithm to pick colors from the multiple color storage areas respectively to obtain multiple color storage blocks, and acquires color storage information of the first image.

[0118] Exemplarily, the electronic device can use the minimum difference method, median segmentation method, octree algorithm, clustering, color modeling method, etc. to extract the color of the color storage area to obtain the color storage information of the first image. The color storage information of the first image includes the position information of multiple color storage blocks of the first image (the geographical location coordinates of all endpoints of any color storage block, and can also be the coordinates and side length of the center point of any color storage block, or the geographical location coordinates and side length of one endpoint of any color storage block. It is not specifically limited here how to characterize the position information of any color storage block) and the color information corresponding to multiple color storage blocks (for example, the RGB value corresponding to the color storage block). Optionally, the color storage information of the first image can also include the label of the color storage block.

[0119] For example, as shown in Table 1 below, the color storage information of the first image stored by the electronic device includes the number of the color storage block, the position information of the color storage block, and the color information corresponding to the color storage block. For example, the position information of color storage block 1 is (15, 15) (15, 45) (45, 15) (45, 45), and the color information corresponding to color storage block 1 is RGB (100, 150, 120). This is merely an example and is not a limitation.

[0120] Table 1

[0121]

[0122] like Figure 6 As shown, the first image is a background image of a portrait. After dividing the first image into multiple grids of the same size, the intermediate color value of each grid is obtained. Figure 6 In this example, the RGB value of the middle pixel of the grid is used as the middle color value. The electronic device connects multiple grid regions to obtain multiple color storage regions, extracts colors from each of the multiple color storage regions, and obtains multiple color storage blocks (color storage blocks 1 to 8). The electronic device then obtains and stores the color storage information of the first image.

[0123] It should be noted that before the electronic device executes step S2, the electronic device may determine whether the first condition is met, and execute step S2 when the first condition is met. When the first condition is not met, the electronic device does not execute the above step S2, that is, the grid areas are not connected. The electronic device may divide the first image into multiple grid areas of the same size, and then sample the multiple grid areas separately to obtain the color storage information of the first image. Among them, the first condition includes one or more of the following: the area of ​​the first image is greater than or equal to the first area threshold (for example, the area of ​​the first image is 30 cm * 24 cm, the first area threshold is 20 cm * 20 cm, then the area of ​​the first image is greater than the first area threshold, or the first area threshold is 80% of the screen area of ​​the electronic device, the electronic device is a computer, the size of the computer is 35.6 cm * 24.5 cm, and the first area threshold is 35.6 cm * 24.5 cm * 80%. This is only an example, and the value of the first area threshold is not specifically limited. , which can be flexibly set based on the needs of actual applications); or, the color picking areas are discretely distributed (for example, the color picking areas are fixed and multiple, and the color picking areas are discretely distributed in the screen of the electronic device, and the color picking areas are distributed in the upper right, lower right, middle, upper left, lower left, etc. of the screen); or, the area of ​​the color picking area is greater than or equal to the second area threshold, and the second area threshold is related to the area of ​​the first image (for example, the area of ​​the first image is 30 cm * 24 cm, and the area of ​​the color picking area is 20 cm * 24 cm, for example, the second area threshold is 50% of the area of ​​the first image).

[0124] In another possible implementation, multiple electronic devices all store color storage information for a first image. When applying the solution of this application, if an electronic device does not store the color storage information for the first image, it may request the color storage information from another electronic device that does store the color storage information for the first image. For example, if electronic device 1 and electronic device 2 both store the color storage information for the first image, but electronic device 3 does not, electronic device 3 may request the color storage information for the first image from either electronic device 1 or electronic device 2. This is merely an example and not a limitation.

[0125] After obtaining the stored color information of the first image, the electronic device may also obtain the position information of the color-picking region in the first image to determine the color of the color-picking region. For example, the stored color information of the first image and the position information of the color-picking region in the first image may be input into an artificial intelligence processing model to obtain the color of the color-picking region, or data processing may be performed based on the stored color information of the first image and the position information of the color-picking region in the first image to obtain the color of the color-picking region, without specific limitation herein.

[0126] For example, the electronic device determines the proportion (e.g., area proportion) of each color storage block in the color picking area and the color storage information of the first image based on the position information of the color picking area and the color storage information of the first image; and performs color block fusion based on the proportion of each color storage block in the color picking area and the color information corresponding to each color storage block in the color picking area to determine the color of the color picking area. Based on this, the color of the color picking area can be clearly determined.

[0127] Specifically, color block fusion includes one of the following methods:

[0128] Method 1: If the color picking area includes a color block with a first proportion, weighted averaging is performed on each color storage block in the color picking area according to the proportion, wherein the first color storage block is a color storage block that accounts for more than 80% of the area in the color picking area.

[0129] For example, Figure 7 As shown, the color picking area in the first image is the portion selected by the rectangular frame, and the color picking area includes the color storage blocks 5, 6, 7, 9, and 10 of the first image. Figure 7 Different fill values ​​represent different RGB values. For example, the area of ​​color storage block 7 accounts for 80% of the color selection area, the area of ​​color storage block 5 accounts for 5%, the area of ​​color storage block 6 accounts for 5%, the area of ​​color storage block 9 accounts for 5%, and the area of ​​color storage block 10 accounts for 5%. Color storage block 7 is the first proportional color block. The color corresponding to the color selection area is obtained by taking the weighted average of the RGB values ​​corresponding to color storage blocks 5, 6, 7, 9, and 10 and the proportion of each color storage block's area in the color selection area. The weighted average is the RGB value of color storage block 5 (25, 25, 25) multiplied by 5% of the area of ​​color storage block 5, plus the RGB value of color storage block 6 (50, 50, 50) multiplied by 5% of the area of ​​color storage block 6, plus the RGB value of color storage block 7 (125, 125, 125) multiplied by 80% of the area of ​​color storage block 7, plus the RGB value of color storage block 9 (150, 150, 150) multiplied by 5% of the area of ​​color storage block 9, plus the RGB value of color storage block 10 (5, 5, 5) multiplied by 5% of the area of ​​color storage block 10, to obtain the value (115, 115, 115). This is merely an example and is not a specific limitation.

[0130] Method 2: If the color picking area includes multiple second proportion color blocks, after adjusting the weights of the color storage blocks corresponding to the multiple second proportion color blocks, the color storage blocks in the color picking area are weighted averaged. Among them, the multiple second proportion color blocks are color storage blocks with the same category of color, and the area and proportion of the multiple second proportion color blocks in the color picking area are greater than 80%. For example, after the RGB value of the second proportion color block is converted to Lab value, if the Euclidean distance between the multiple second proportion color blocks is less than the distance threshold, the second proportion color block is considered to be a color storage block with the same category of color. This is only an example and is not specifically limited.

[0131] For example, Figure 8 As shown, the color extraction area in the first image is the portion selected by the rectangular frame, and the color extraction area includes color storage blocks 8, 9, 10, 11, 12, and 14 of the first image. Among them, color storage blocks 8, 9, and 14 are color storage blocks of the same color category (for example, red), and the total area of ​​color storage blocks 8, 9, and 14 accounts for 80% of the color extraction area. Among them, the area of ​​color storage block 8 accounts for 20% of the color extraction area, the area of ​​color storage block 9 accounts for 20% of the color extraction area, the area of ​​color storage block 14 accounts for 40% of the color extraction area, the area of ​​color storage block 10 accounts for 10% of the color extraction area, the area of ​​color storage block 11 accounts for 5% of the color extraction area, and the area of ​​color storage block 12 accounts for 5% of the color extraction area. Adjust the weight of the second color block to 90% and the weight of the other color storage blocks to 10%. Then the area of ​​color storage block 8 accounts for 22.5% (90%*2 / 8) of the color picking area, the area of ​​color storage block 9 accounts for 22.5% (90%*2 / 8) of the color picking area, the area of ​​color storage block 14 accounts for 45% (90%*4 / 8) of the color picking area, the area of ​​color storage block 10 accounts for 5% (10%*1 / 2) of the color picking area, the area of ​​color storage block 11 accounts for 2.5% (10%*1 / 4) of the color picking area, and the area of ​​color storage block 12 accounts for 2.5% (10%*1 / 4) of the color picking area. The weighted average can be understood by referring to the description in the above method 1 and will not be repeated here.

[0132] Method 3: If the color selection area includes multiple color blocks with a third percentage, the color purity is reduced by weighted averaging the color blocks in the color selection area based on their percentages. The multiple color blocks with a third percentage are color blocks of the same color category, and their combined area and percentage within the color selection area do not exceed 80%.

[0133] For example, Figure 9As shown, the color extraction area in the first image is the portion selected within the rectangular frame, and the color extraction area includes color storage blocks 8, 9, 10, 11, 12, and 14 of the first image. Color storage blocks 8, 9, and 14 are color storage blocks of the same color (e.g., red), and their combined area accounts for 60% of the color extraction area. The area of ​​color storage block 8 accounts for 20% of the color extraction area, the area of ​​color storage block 9 accounts for 20% of the color extraction area, the area of ​​color storage block 14 accounts for 20% of the color extraction area, the area of ​​color storage block 10 accounts for 10% of the color extraction area, the area of ​​color storage block 11 accounts for 5% of the color extraction area, and the area of ​​color storage block 12 accounts for 5% of the color extraction area. Exemplarily, after the electronic device performs weighted averaging on color storage blocks 8, 9, 10, 11, 12, and 14, the obtained RGB values ​​are converted into Lab values, and then converted into LCH values ​​(L (brightness), C (chroma), H (hue angle)), wherein the values ​​of L and H remain unchanged, and the value of C is reduced (for example, the value of C is reduced from 100 to 80, and the specific reduction amount is not specifically limited here and can be flexibly set based on the needs of actual applications), and then converted into Lab values, and then converted into RGB values ​​to obtain a value that reduces color purity. Alternatively, the electronic device performs weighted averaging on the color storage blocks 8, 9, 10, 11, 12, and 14, converts the obtained RGB values ​​into Lab values, and then converts them into HSV values ​​(wherein, hue (H), saturation (S), and value (V), where the values ​​of H and V remain unchanged, and the value of S is reduced (for example, the value of S is reduced from 100 to 80, and the specific reduction amount is not specifically limited here, and can be flexibly set based on the needs of actual application), and then converts them into Lab values, and then converts them into RGB values ​​to obtain a value for reducing color purity. This is only an example description and is not specifically limited. In specific applications, other schemes for reducing color purity may also be involved. The above is only an example description and is not specifically limited here.

[0134] In addition, if Figure 10 As shown, the color picking area changes dynamically. Figure 10 is Figure 7 Specifically, one of the above methods 1 to 3 may be referred to to perform color block fusion to determine the color of the fused color-picking area.

[0135] In this application, the electronic device pre-acquires the color storage information of the first image, and determines the color of the color picking area based on the color storage information and the position information of the color picking area. This method does not repeatedly use the color picking algorithm to calculate the color of the color picking area, which can reduce the computing consumption of the processor and ensure the color picking effect.
