It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in other than the order illustrated

[0051] The order of description herein may not encompass all of the

[0052] Reference Figure 1 The first aspect of the present application provides a method for generating a picture light-emitting special effect, comprising the following steps:

[0053] S100, receiving a user uploaded original picture for making a light-emitting special effect, the pattern in the original picture is opaque, and other parts of the original picture except the pattern are completely transparent; Specifically, the technical solution of the present application is mainly applicable to pictures with a certain fixed format, for example Figure 2 In this picture, there are some patterns Figure 2 Chinese characters) in the picture, the text is the opaque part of the picture, and the other parts are completely transparent. The text here corresponds to the pattern in the picture;

[0054] S200, executing a picture copying instruction in the background to generate a background picture for making a light-emitting layer texture; in the present application, the main function of the background picture is to extract the pattern part in the background picture by a method similar to matting, and to enlarge the extracted part according to the set text peripheral aperture size; Figure One

[0055] S300, performing an expansion processing based on pixel color replacement on the pattern in the background picture to obtain a light-emitting layer texture of the pattern; in the present application, the pattern part is directly processed by one step to place by using the pixel color replacement method, so as to improve the processing efficiency;

[0056] S400, performing horizontal and vertical blur processing on each pixel point in the light-emitting layer texture; in the present application, the main function of the blur processing is to make the text part more prominent after the subsequent light-emitting special effect fusion, so as to not affect the clarity of the original picture;

[0057] S500, calculating a color mixing coefficient of each pixel point of the pattern in the original picture based on the transparency of each pixel point of the pattern and a light transmission percentage parameter set by the user; in the present application, the function of the color mixing coefficient is to make the subsequent pattern and light-emitting layer texture fusion more natural;

[0058] ​S600, fusing the pattern in the original picture and the luminescent layer texture in the background picture after the blur processing based on the color mixing coefficient, to obtain a luminescent special effect picture. In the present application, in order to make the fusion more convenient, the fusion of the pattern and the luminescent layer texture is to fuse the pattern into the picture where the luminescent layer texture is located.

[0059] Specifically, the present application is applicable to any picture with a pattern (the pattern is not limited to text) in the picture style defined in S100, and the pattern has a luminescent effect. The luminescent effect of the present application can be set to any color in step S300, and the luminescent intensity and the pattern transparency can be set in step S500. The present application can be used in various scenes and has wide applicability. The method is to enlarge the pattern, blur the enlarged picture to obtain a luminescent layer, and then mix the luminescent layer with the picture to generate the luminescent effect.

[0060] In an optional embodiment of the first aspect of the present application, the pixel color replacement-based enlargement processing of the pattern in the background picture to obtain the luminescent layer texture of the pattern comprises:

[0061] In the background picture, for each pixel point, it is determined whether there is an opaque pixel point on a circle with a user-set aperture size as a radius and the pixel point as a center point;

[0062] If there is an opaque pixel point, the color of the pixel point is set to the color of the user-set luminescent special effect, and the transparency of the pixel point is set to be completely opaque. In the present application, if an opaque pixel point is found, it means that the current pixel is within the luminescent range, and the current pixel point is set to the corresponding luminescent color and opaque, for example, white opaque 0xFFFFFFFF (RGBA);

[0063] If there is an opaque pixel point, the color of the pixel point is set to black, and the transparency of the pixel point is set to be completely transparent. In the present application, if no opaque pixel point is found, it means that the current pixel is not within the luminescent range, and the current pixel point is set to black and completely transparent 0x00000000 (RGBA). In the present application, the enlarged background picture is shown in Figure 3

[0064] In an optional embodiment of the first aspect of the present application, the horizontal and vertical blur processing of each pixel point in the luminescent layer texture comprises:

[0065] ​In the horizontal blur processing of the pixels in the light-emitting layer texture, for each pixel, a first blur coefficient corresponding to each pixel in a first distance range on the left and right sides of the pixel is calculated by a preset relationship between the blur coefficient, the distance from the pixel and the user-set aperture virtual-real parameter.

[0066] The product of the initial color value of each pixel and the first blur coefficient corresponding to each pixel is calculated, and a first accumulated value is obtained by accumulating the products calculated for each pixel in the first distance range on the left and right sides of the pixel, and the first accumulated value is used as a first calculated color value of the pixel.

[0067] Specifically, in the present application, the light-emitting layer texture is blurred, and the blurring needs to be performed twice, once in the horizontal direction and once in the vertical direction. When blurring in the horizontal direction, the processing method for each pixel is as follows: the pixel color within a distance range B (aperture virtual-real parameter, unit: pixel, the larger B is, the more virtual the aperture is) on the left and right of the current pixel is multiplied by a blur coefficient Blur, and all the results are accumulated.

[0068] The blur coefficient Blur is calculated based on the distance between the pixel and the current pixel, and the specific formula is as follows:

[0069] wherein D is the distance between each pixel and the current pixel in the horizontal direction, and B is the aperture virtual-real parameter;

[0070] The color LightColor of a single pixel in the light-emitting layer texture when blurring in the horizontal direction is the result of accumulating the pixel color within a distance range B multiplied by the blur coefficient Blur, and the calculation formula is as follows:

[0071]

[0072] In an optional embodiment of the first aspect of the present application, the horizontal and vertical blur processing of the pixels in the light-emitting layer texture further comprises:

[0073] Based on the first calculated color value of each pixel, in the vertical blur processing of the pixels in the light-emitting layer texture, for each pixel, a second blur coefficient corresponding to each pixel in a second distance range on the upper and lower sides of the pixel is calculated by a preset relationship between the blur coefficient, the distance from the pixel and the user-set aperture virtual-real parameter.

[0074] The product between the calculated color value of each pixel point and the second blur coefficient corresponding to each pixel point is recalculated, the products calculated from each pixel point in the second distance range on the left and right sides of the pixel point are accumulated, and a second accumulated value is obtained, and the second accumulated value is used as the final calculated color value of the pixel point.

[0075] In the present application, the vertical direction and the horizontal direction are similar, but in the vertical direction, the pixel points in the distance range within B (up and down) are taken, and the background image after horizontal and vertical blur processing of each pixel point in the luminescent layer texture can be as shown in Figure 4

[0076] In another optional embodiment of the first aspect of the present application, the horizontal and vertical blur processing of each pixel point in the luminescent layer texture comprises:

[0077] When performing horizontal blur processing on each pixel point in the luminescent layer texture, for each pixel point, the sum of the initial color values of all pixel points in the third distance range on the left and right sides of the pixel point is calculated, and the sum is multiplied by a third blur coefficient to obtain a first calculated color value of the pixel point.

[0078] On the basis of the calculation of the first calculated color value of each pixel point, when performing vertical blur processing on each pixel point in the luminescent layer texture, for each pixel point, the sum of the first calculated color values of all pixel points in the second distance range on the upper and lower sides of the pixel point is calculated, and the sum is multiplied by a fourth blur coefficient to obtain a final calculated color value of the pixel point.

[0079] In the present application, another method for performing horizontal and vertical blur processing on each pixel point in the luminescent layer texture is also included, which uses a method of multiplying all total pixel value colors by a fixed blur coefficient. Although this method is not as effective as the previously mentioned blur method, it can also meet the requirements of horizontal and vertical blur processing on each pixel point in the luminescent layer texture.

[0080] In an optional embodiment of the first aspect of the present application, the calculation of the color mixing coefficient of each pixel point in the pattern based on the transparency of the pixel point in the original image and the light transmission percentage parameter set by the user comprises:

[0081] For each pixel point, if the transparency of the pixel point is less than or equal to the light transmission percentage, the color mixing coefficient is equal to zero.

[0082] ​If the transparency of the pixel point is greater than the light transmission percentage, the color mixing coefficient is equal to the transparency minus the light transmission percentage.

[0083] Specifically, in the present application, the original picture is mixed with the light-emitting picture, first, the pixel color LightColor in the light-emitting texture at the current position of the pixel is obtained, and the color Color and the transparency Alpha of the pixel in the picture are obtained, the mixing is divided into two steps,

[0084] The first step is to obtain the mixing coefficient f, and the formula is as follows:

[0085] T is the light transmission percentage.

[0086] In an optional embodiment of the first aspect of the present application, the fusion processing of the pattern in the original picture and the light-emitting layer texture in the blurred background picture based on the color mixing coefficient to obtain the light-emitting special effect picture includes:

[0087] The center alignment processing is performed on the pattern and the light-emitting layer texture;

[0088] The color fusion of the same position pixel points is performed from the center pixel point of the pattern and the center pixel point of the light-emitting layer texture;

[0089] For two pixel points at the same position, the mixed color of the two pixel points = the final calculated color value of the pixel point in the light-emitting layer texture *(1-the color mixing coefficient of the pixel point in the pattern)+ the color value of the pixel point in the pattern * the color mixing coefficient of the pixel point in the pattern.

[0090] In the present application, after obtaining the color mixing coefficient, the color mixing is performed using the color mixing coefficient f to obtain the final color FinalColor of the pixel, and the formula is as follows:

[0091] FinalColor = LightColor *(1-f) + Color *f, in the present application, the picture after the fusion processing is as shown in Figure 5 .

[0092] Embodiment

[0093] In order to better illustrate the technical scheme of the present application, the present application exemplarily provides a full-process embodiment as follows:

[0094] (1)First, prepare a picture with transparency, and the picture has some patterns, which means the non-transparent part of the picture, for example, the following picture with transparency, the text part is not transparent, and the other part is completely transparent, and the text here is the corresponding pattern.

[0095] (2) Then set the following parameters

[0096] Aperture size S (custom parameter, which can be understood as how wide the light range needs to be generated at the edge of the pattern), unit pixel, S represents the size of the aperture, the larger S, the larger the aperture;

[0097] Aperture virtual-real parameter B (custom parameter, which can be understood as the range of pixels that need to be blurred around the edge of the pattern), unit pixel, the larger B, the more virtual the aperture;

[0098] Light transmission percentage T (i.e. the light transmission rate of each pixel), range [0.0, 1.0].

[0099] (3) Then copy a picture, and enlarge the pattern in the copied picture to get the light layer texture, the enlargement method is as follows:

[0100] For each pixel, in the picture, find out whether there is a non-transparent pixel on the circle with a radius of S;

[0101] If a non-transparent pixel is found, it means that the current pixel is within the light range, then set the current pixel to the corresponding light color and non-transparent, for example, set it to white non-transparent 0xFFFFFFFF (RGBA);

[0102] If no non-transparent pixel is found, the current pixel is not within the light range, then set the current pixel to black completely transparent 0x00000000 (RGBA).

[0103] (4) Then blur the light layer texture, which needs to be done twice, once in the horizontal direction and once in the vertical direction;

[0104] When blurring in the horizontal direction, the processing method for each pixel is: take the pixel color within the distance range of B in the horizontal direction (left and right) of the current pixel, multiply it by the blur coefficient Blur, and add all the results.

[0105] Blur coefficient Blur is calculated by the distance of the pixel from the current pixel, and the specific formula is as follows:

[0106] Where D is the distance, and B is the virtual-real of the aperture

[0107] LightColor is the result of multiplying the pixel color within the distance range B in the horizontal direction by the blur coefficient Blur, and the calculation formula is:

[0108]

[0109] Similar to the horizontal direction, only in the vertical direction, the pixel within the distance range B (up and down) is taken.

[0110] (5) Finally, the original picture is mixed with the light-emitting picture. First, get the pixel color LightColor in the light-emitting texture at the current position of the pixel, and the color Color and transparency Alpha of the pixel in the picture, and the mixing is divided into two steps,

[0111] The first step is to obtain the mixing coefficient f, and the formula is as follows:

[0112] T is the parameter of the light transmission percentage.

[0113] The second step uses the mixing coefficient f to perform color mixing to obtain the final color FinalColor of the pixel, and the formula is as follows:

[0114] FinalColor=LightColor*(1-f)+Color*f.
