[0012] The color adjustment unit is used to determine the target color parameter range corresponding to the first color parameter based on the first target color parameter and the second target color parameter, and to perform color adjustment processing on the target pixels in the initial media content that belong to the target color parameter range to generate target media content.

[0017] Fifthly, embodiments of this disclosure provide a computer program product, including a computer program that, when executed by a processor, implements the media content editing method described in the first aspect and various possible designs of the first aspect.

[0018] This embodiment provides a method, apparatus, device, storage medium, and program product for editing media content. The method includes: obtaining a first color parameter corresponding to a color adjustment operation, wherein the color adjustment operation is used to perform color adjustment processing on pixels in the initial media content that belong to the color parameter range corresponding to the first color parameter; determining a first target color parameter from a first color parameter range where the color parameter is greater than the first color parameter, and determining a second target color parameter from a second color parameter range where the color parameter is less than the first color parameter; wherein the color difference between the first target color parameter and the first color parameter is a first preset color difference, and the color difference between the second target color parameter and the first color parameter is a second preset color difference; determining a target color parameter range corresponding to the first color parameter based on the first target color parameter and the second target color parameter, performing color adjustment processing on target pixels in the initial media content that belong to the target color parameter range, and generating target media content.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0028] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of related data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0029] Currently, HSL (Hue Saturation Lightness) color correction is a widely used method. This method allows adjustment of pixels within a specific range of color parameters in an image. In other words, pixels whose color parameters fall within this range are selected and participate in subsequent color correction. Therefore, improving the accuracy of the selected color parameter range is crucial for achieving the desired color correction effect.

[0030] In related technologies, different colors correspond to color parameter ranges of the same size, and color correction using color parameter ranges of the same size yields poor results. In such cases, pixels within a specific color parameter range in the image can be manually adjusted. However, manual adjustment not only increases the number of interactions in image editing but also heavily relies on the operator's color correction experience; otherwise, it is often difficult to select a suitable color parameter range.

[0031] For example, such as Figure 1As shown, the color parameter ranges for yellow, green, and blue are the same. In this case, the color correction effect can be improved by manually adjusting the color parameter ranges for each color. However, manually adjusting the color parameter ranges for each color not only increases the number of interactions in image editing but also heavily relies on the operator's color correction experience, therefore the accuracy of the color parameter ranges after each manual adjustment cannot be guaranteed.

[0032] To address the technical problems in existing technologies, the inventor's technical concept is as follows: For a given color parameter, taking it as the center, find two color parameters on the left and right sides that are greater than a given color difference (denoted as p). The range covered by these two color parameters is the desired color parameter range. In other words, by using color difference theory as the selection criterion, the color parameter range is determined, reducing reliance on human experience and thus improving the accuracy of the desired color parameter range.

[0033] Accordingly, the specific steps may include: obtaining a first color parameter corresponding to the color adjustment operation, wherein the color adjustment operation is used to perform color adjustment processing on pixels in the initial media content that belong to the color parameter range corresponding to the first color parameter; determining a first target color parameter from the first color parameter range where the color parameter is greater than the first color parameter, and determining a second target color parameter from the second color parameter range where the color parameter is less than the first color parameter; wherein the color difference between the first target color parameter and the first color parameter is a first preset color difference, and the color difference between the second target color parameter and the first color parameter is a second preset color difference; determining the target color parameter range corresponding to the first color parameter based on the first target color parameter and the second target color parameter, performing color adjustment processing on target pixels in the initial media content that belong to the target color parameter range, and generating target media content.

[0034] In this technical solution, for the initial media content to be color-corrected, with the first color parameter as the center, the color parameter ranges in the two directions to the left and right of the first color parameter are determined according to the size of the color difference with the first color parameter. The first target color parameter with the size of the color difference is the first preset color difference, and the second target color parameter with the size of the color difference is the second preset color difference. In this way, for the first color parameter corresponding to different color correction operations, the target color parameter range that matches the first color parameter can be determined, thereby improving the accuracy of the determined target hue range and thus improving the effect of color correction processing on the media content.

[0035] The following is a detailed implementation process of the media content editing method according to the embodiments of this disclosure. Some examples are merely illustrative and not intended to limit the scope. The executing entity of the media content editing method according to the embodiments of this disclosure is an electronic device, such as a terminal or server.

[0036] Figure 2 Flowchart of the media content editing method provided in the embodiments of this disclosure Figure 1 ,like Figure 2 As shown, the methods for editing this media content may include:

[0037] S201. Obtain the first color parameter corresponding to the color adjustment operation. The color adjustment operation is used to perform color adjustment processing on the pixels in the initial media content that belong to the color parameter range corresponding to the first color parameter.

[0038] In this embodiment of the disclosure, the first color parameter can be an RGB color parameter or an HSL color parameter. The first color parameter can be a user-specified color. That is, the user can specify color adjustment for pixels of a certain color in the media content. The media content can be video or an image.

[0039] In some embodiments, when the first color parameter is an RGB color parameter, the RGB color parameter can be converted to an HSL color parameter to determine the color parameter range corresponding to the first color parameter. Accordingly, this step may include: obtaining the RGB color parameter corresponding to the target color selected in the color adjustment operation; converting the RGB color parameter to an HSL color parameter to obtain the first color parameter corresponding to the color adjustment operation; wherein, the first color parameter includes a first hue parameter, a first brightness parameter, and a first saturation parameter.

[0040] In other embodiments, the first color parameter is an HSL color parameter. In this case, an HSL color parameter input box can be displayed on the media content editing interface. Before triggering the color adjustment operation, the user can input the HSL color parameter in the HSL color parameter input box. Accordingly, this step may include: when triggering the color adjustment operation, the electronic device obtains the HSL color parameter input in the HSL color parameter input box to obtain the first color parameter corresponding to the color adjustment operation.

[0041] In this embodiment, the color parameter range can be the range of HSL color parameters. HSL color parameters better align with users' intuitive understanding of color, describing color from three dimensions: hue, saturation, and brightness. Hue refers to the basic attribute of color, such as red, blue, and green. The distribution of hues forms a circle, so in the HSL model, the unit of hue is "degree," for example, 0 degrees represents red, 120 degrees represents green, etc. Saturation refers to the vividness of a color. Low-saturation colors appear grayish, down to pure gray; high-saturation colors are vivid, such as pure red and pure green. Brightness refers to the lightness or darkness of a color. Colors can range from black to white. For example, when we say "dark green, light purple," "green" and "purple" are descriptions of hue, while "dark" and "light" are combined descriptions of saturation and brightness.

[0042] S202. Determine a first target color parameter from a first color parameter range where the color parameter is greater than the first color parameter, and determine a second target color parameter from a second color parameter range where the color parameter is less than the first color parameter; wherein the color difference between the first target color parameter and the first color parameter is a first preset color difference, and the color difference between the second target color parameter and the first color parameter is a second preset color difference.

[0043] In this embodiment of the disclosure, for ease of calculation, the saturation parameter in each first candidate color parameter can be set to be the same as the first saturation parameter in the first color parameter, and the brightness parameter in each first candidate color parameter can be set to be the same as the first brightness parameter in the first color parameter. This embodiment of the disclosure does not impose specific limitations on the values ​​of the saturation parameter and the brightness parameter; they can be set and changed as needed.

[0044] For example, such as Figure 3 As shown, the first color parameter includes a first hue parameter, a first brightness parameter, and a first saturation parameter. The first saturation parameter S can be set to 1, and the first brightness parameter L to 0.5. The first hue parameter can be denoted as H0. In this case, the first color parameter can be denoted as C0 = (H0, 1, 0.5).

[0045] In some embodiments, a first target color parameter is determined from a range of first color parameters based on the color difference between a first candidate color parameter and the first color parameter, using a first color parameter as the central color parameter. Correspondingly, determining the first target color parameter from a range of first color parameters where the color parameter is greater than the first color parameter includes: using the first color parameter as the initial color parameter, selecting first candidate color parameters from the range of first color parameters in ascending order of color parameters, wherein the color difference interval between two adjacent first candidate color parameters is a preset color difference interval; determining the color difference between the first candidate color parameter and the first color parameter; if the color difference is less than a first preset color difference, then selecting the next first candidate color parameter; if the color difference is equal to the first preset color difference, then determining the first candidate color parameter as the first target color parameter. In this embodiment, the value of the preset color difference interval is not specifically limited and can be set and changed as needed. For example, the preset color difference interval is 1 degree.

[0046] For example, such as Figure 3 As shown, using the first color parameter as the initial color parameter, and selecting the first candidate color parameter from the range of the first color parameter in ascending order of color parameters, the first candidate color parameter is recorded as C. R = (H, 1, 0.5). The color difference between the first candidate color parameter and the first color parameter can be expressed as delta E(C). RThe first preset color difference can be represented as p1. When delta E(C0). R When C0) is less than the first preset color difference p1, continue to select the next first candidate color parameter; when delta E(C) is less than the first preset color difference p1, continue to select the next first candidate color parameter; R When C0) equals the first preset color difference p1, the first candidate color parameter at this time is determined as the first target color parameter, and H at this time (that is, the first target hue parameter in the first target color parameter) is denoted as H. R .

[0047] In some embodiments, a first color parameter is used as the central color parameter, and a second target color parameter is determined from the range of second color parameters based on the color difference between the second candidate color parameter and the first color parameter. Correspondingly, determining the second target color parameter from the range of second color parameters whose color parameters are smaller than the first color parameter includes: using the first color parameter as the initial color parameter, selecting second candidate color parameters from the range of second color parameters in descending order of color parameters, wherein the color difference interval between two adjacent second candidate color parameters is a preset color difference interval; determining the color difference between the second candidate color parameter and the first color parameter; if the color difference is less than a second preset color difference, then selecting the next second candidate color parameter; if the color difference is equal to the second preset color difference, then determining the second candidate color parameter as the second target color parameter. In this embodiment, the value of the preset color difference interval is not specifically limited and can be set and changed as needed. For example, the preset color difference interval is 1 degree.

[0048] It should be noted that the color difference interval between the two second candidate color parameters can be the same as or different from the color difference interval between the two first candidate color parameters.

[0049] For example, such as Figure 3 As shown, using the first color parameter as the initial color parameter, and selecting the second candidate color parameter from the range of the second color parameter in descending order of color parameter, the second candidate color parameter is recorded as C. L = (H, 1, 0.5). The color difference between the second candidate color parameter and the first color parameter can be expressed as delta E(C). L The second preset color difference can be represented as p2. When delta E(C L When C0) is less than the second preset color difference p2, continue to select the next first candidate color parameter; when delta E(C L When C0) equals the second preset color difference p2, the second candidate color parameter at this time is determined as the second target color parameter, and H at this time (that is, the second target hue parameter in the second target color parameter) is denoted as H. L .

[0050] In this embodiment of the disclosure, the values ​​of the first preset color difference and the second preset color difference are not specifically limited. The first preset color difference and the second preset color difference can be set to be the same, or the first preset color difference and the second preset color difference can be set to be different.

[0051] It should be noted that color difference is used to measure the difference between two colors. Generally, this difference refers to a person's subjective perception of color difference. Color difference theory, on the other hand, uses certain mathematical theories (formulas) to fit a person's subjective perception of color difference. In this disclosure, the method for determining color difference is not specifically limited. For example, such as... Figure 3 As shown, delta E can be used to refer to the color difference calculated theoretically.

[0052] S203. Based on the first target color parameter and the second target color parameter, determine the target color parameter range corresponding to the first color parameter, and perform color adjustment on the target pixels in the initial media content that belong to the target color parameter range to generate the target media content.

[0053] In some embodiments, target pixels in the initial media content that fall within the target color parameter range, that is, the color parameters corresponding to the target pixels are located within the target color parameter range. In this case, this application adaptively selects the target color parameter range corresponding to the target color, with the target color center as the target color.

[0054] In other embodiments, the brightness and saturation parameters of each pixel in the initial media content are the same or similar, so the brightness and saturation parameters in the color parameters can be set to fixed values. For example, the saturation parameter S = 1 and the brightness parameter L = 0.5 can be set. In this case, the target pixels in the initial media content that belong to the target color parameter range can be determined by using the hue parameter corresponding to each pixel in the initial media content.

[0055] Optionally, this step includes: determining the target color parameter range corresponding to the first color parameter based on the first target color parameter and the second target color parameter; determining the target hue parameter range corresponding to the target color parameter range; and performing color adjustment processing on the target pixels in the initial media content that belong to the target hue parameter range to generate the target media content.

[0056] For example, such as Figure 3 As shown, the first target color parameter is C. L =(H L The second target color parameter is C (1, 0.5). R =(H R The target color parameter range is [C, 1, 0.5). L C R The corresponding target hue parameter range is [H].L H R At this point, the initial media content can be selected from the target hue parameter range [H]. L H R The target pixels within the range are color-corrected to generate the target media content.

[0057] In this embodiment of the disclosure, the first target color parameter includes a first target hue parameter, and the second target color parameter includes the first target hue parameter. The first target hue parameter and the second target hue parameter belong to the hue parameter range on a hue wheel from 0 degrees to 360 degrees.

[0058] Optionally, if the first target hue parameter is greater than or equal to 0 degrees and less than 360 degrees, and the second target hue parameter is greater than or equal to 0 degrees and less than 360 degrees, then no adjustment is needed for the first and second target hue parameters when determining the target color parameter range. If the first target hue parameter is less than 0 degrees or greater than 360 degrees, then a remainder operation of 360 degrees needs to be performed on the first target hue parameter when determining the target color parameter range to ensure that the first target hue parameter belongs to the hue parameter range on the hue wheel from 0 degrees to 360 degrees. Similarly, if the second target hue parameter is less than 0 degrees or greater than 360 degrees, then a remainder operation of 360 degrees needs to be performed on the second target hue parameter when determining the target color parameter range to ensure that the second target hue parameter belongs to the hue parameter range on the hue wheel from 0 degrees to 360 degrees.

[0059] For example, the first target hue parameter is 370 degrees, which becomes 10 degrees after modulo operation. The second target hue parameter is -100 degrees, which becomes 260 degrees after modulo operation. The determined target color parameter range is: [(10,1,0.5),(260,1,0.5)].

[0060] This disclosure provides a method for editing media content: obtaining a first color parameter corresponding to a color adjustment operation, the color adjustment operation being used to adjust the color of pixels in the initial media content that belong to the color parameter range corresponding to the first color parameter; determining a first target color parameter from the first color parameter range where the color parameter is greater than the first color parameter, and determining a second target color parameter from the second color parameter range where the color parameter is less than the first color parameter; wherein the color difference between the first target color parameter and the first color parameter is a first preset color difference, and the color difference between the second target color parameter and the first color parameter is a second preset color difference; determining the target color parameter range corresponding to the first color parameter based on the first target color parameter and the second target color parameter, and performing color adjustment on target pixels in the initial media content that belong to the target color parameter range to generate target media content. In this technical solution, for the initial media content to be color-corrected, with the first color parameter as the center, the color parameter ranges in the two directions to the left and right of the first color parameter are determined according to the size of the color difference with the first color parameter. The first target color parameter with the size of the color difference is the first preset color difference, and the second target color parameter with the size of the color difference is the second preset color difference. In this way, for the first color parameter corresponding to different color correction operations, the target color parameter range matching the first color parameter can be determined, thereby improving the accuracy of the determined target hue range and thus improving the effect of color correction processing on the media content.

[0061] In this embodiment of the disclosure, to improve the effect of color correction processing of media content, the edge regions of the target color parameter range can be feathered. Furthermore, different feathering ranges can be provided for the target color parameter ranges corresponding to different colors.

[0062] In some embodiments, the target color parameter range includes the range of HSL color parameters. The HSL color parameters include hue, saturation, and brightness. Saturation and brightness can be set to fixed values. In this case, feathering can be applied to the edge regions of the target color parameter range; that is, feathering is applied to the edge regions of the hue parameters within the target color parameter range.

[0063] Optionally, the first color parameter includes a first hue parameter, the first target color parameter includes a first target hue parameter, and the second target color parameter includes a first target hue parameter. Correspondingly, as... Figure 4 As shown, the above feathering method may include the following steps:

[0064] S401. Based on the first target hue parameter and the first hue parameter, determine the first hue feathering parameter corresponding to the first target hue parameter; and based on the second target hue parameter and the first hue parameter, determine the second hue feathering parameter corresponding to the second target hue parameter.

[0065] Optionally, determining the first hue feathering parameter corresponding to the first target hue parameter based on the first target hue parameter and the first hue parameter includes: determining the difference between the first hue parameter and the first hue parameter; determining the first product between the difference between the first hue parameter and the preset feathering ratio; and determining the first hue feathering parameter corresponding to the first target hue parameter based on the difference between the first target hue parameter and the first product.

[0066] For example, such as Figure 3 As shown, the preset feathering ratio is r, and the first hue feathering parameter HRS = H R -(H R -H0)*r. Where H R H0 represents the first target hue parameter.

[0067] Optionally, based on the second target hue parameter and the first hue parameter, the second hue feathering parameter corresponding to the second target hue parameter is determined, including: determining the difference between the first hue parameter and the second target hue parameter; determining the second product between the difference between the second hue parameters and the preset feathering ratio; and determining the second hue feathering parameter corresponding to the second target hue parameter based on the sum of the second target hue parameter and the second product.

[0068] For example, such as Figure 3 As shown, the preset feathering ratio is r, and the second hue feathering parameter HLS = H L +(H0-H L )*r. Where, H L H represents the second target hue parameter, and H0 represents the first hue parameter.

[0069] S402. Determine the first hue feathering range between the first target hue parameter and the first hue feathering parameter, and determine the second hue feathering range between the second target hue parameter and the second hue feathering parameter.

[0070] For example, such as Figure 3 and Figure 5 As shown, the feathering range of the first hue is (HRS, H). R ), indicating the feathering range on the right. The feathering range for the first hue is (H). L , HLS), indicates the feathering range on the left.

[0071] S403. Feather the target pixels in the initial media content that fall within the first hue feathering range and the second hue feathering range.

[0072] In this embodiment of the disclosure, by feathering the edge regions of the target color parameter range using a first hue feathering range and a second hue feathering range during the color adjustment process, the display smoothness of pixels located in the edge regions of the target color parameter range can be improved, thereby enhancing the display effect of the target media content obtained after color adjustment. Furthermore, different feathering ranges can be provided for different target color parameter ranges, thus increasing the flexibility of the feathering process and further improving the display effect of the target media content.
