It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

As background art, when a user uses a shooting function in different scenes, the problem of insufficient lighting is encountered. For example, when a picture is taken in a dark and weak light environment or a complex light environment, the camera sensor needs to image by depending on the ambient light incident amount to achieve a clear imaging effect, and under such a light environment, the actual light often cannot meet the light incident amount requirement of clear imaging. Therefore, the light supplement lamp can be used to compensate the light required by the camera sensor in the related art.

However, in the related art, a light supplement lamp with a single color is usually used for light supplement, which only can improve the brightness of a shot picture and cannot adapt to color temperatures of light rays in different shooting scenes. For example, in a shooting scene such as a cafe with warm yellow light and a pub with colored light, a white fill light with a higher color temperature may have a larger difference from ambient light. Therefore, the light supplement mode in the related art has a poor light supplement effect, and cannot meet the shooting requirements of users.

In order to solve the problems in the related art, an embodiment of the present application provides a light supplement method, where an electronic device may receive a first input of a user to a first location in a shooting preview interface when the shooting preview interface is displayed, and may acquire color information corresponding to the first location in response to the first input. Based on this, the electronic device can determine the light supplement parameter according to the color information corresponding to the first position, and control the light supplement module in the electronic device to supplement light based on the light supplement parameter. Because the color information of the first position is decided by the light color temperature of the current shooting scene, the light supplementing parameter based on the color information adapted to the first position is used for supplementing light, so that the light supplementing effect is matched with the light color temperature of the current shooting environment, the light supplementing effect is effectively improved, the shooting requirement of a user is met, the problem that the light supplementing mode in the correlation technology cannot adapt to the light color temperature of different shooting scenes and the light supplementing effect is poor is solved.

Fig. 1 is a schematic flow chart of a light supplement method according to an embodiment of the present disclosure, where an execution main body of the light supplement method may be an electronic device, and the electronic device may include a light supplement module. The above-described execution body does not constitute a limitation of the present application.

As shown in fig. 1, the light supplement method provided in the embodiment of the present application may include steps 110 to 140.

Step 110, receiving a first input to a first position in a shooting preview interface under the condition that the electronic device displays the shooting preview interface.

The shooting preview interface can be a preview interface displayed by the electronic equipment in the shooting process of the shooting object, and the preview interface can comprise the shooting object, and the shooting object can be a person, an animal, a plant, a ornament and the like, and the shooting preview interface is not specifically limited in this application.

The first position may be any position selected by the user in the background portion of the shooting preview interface, and the first input may be a click input, a double-click input, a slide input, a long-press input, or a combination of at least two of the above inputs, etc. of the user at the first position, which is not limited in this application.

Illustratively, as shown in fig. 2, the first position may be a position 202 in the shooting preview interface 201, and the second input may be a long press input of the position 202 by the user.

It should be noted that colors presented at different positions in the same shooting preview interface may be different, so that a user may select a target color meeting an expectation from all colors displayed in a background portion of the shooting preview interface, where the position of the target color is the first position. Therefore, the electronic device can determine the light supplement parameter according to the target color, namely the color information corresponding to the first position, so that the light supplement module can feed back light close to the target color based on the light supplement parameter, and the light supplement effect is matched with the light color temperature of the current shooting environment.

Based on different light supplement parameters, different light supplement colors can be presented, so that the light supplement module is controlled to supplement light based on the light supplement parameters, and the light supplement module can present light similar to the target color corresponding to the first position.

In one example, where the photographic environment is a coffee shop with warm yellow light, the first location in the photographic preview interface may appear warm yellow. The electronic device can determine the light supplement parameter according to the color information of the warm yellow corresponding to the first position, and control the light supplement module, for example, a built-in light supplement lamp of the electronic device is controlled to supplement light to the shooting object based on the light supplement parameter, and the light supplement color fed back by the built-in light supplement lamp is the warm yellow.

According to the light supplement method provided by the embodiment of the application, under the condition that the shooting preview interface is displayed by the electronic equipment, the first input of a user to a first position in the shooting preview interface can be received, and the color information corresponding to the first position can be acquired in response to the first input. Based on this, the electronic device can determine the light supplement parameter according to the color information corresponding to the first position, and control the light supplement module in the electronic device to supplement light based on the light supplement parameter. Because the color information of the first position is decided by the light color temperature of the current shooting scene, the light supplementing parameter based on the color information adapted to the first position is used for supplementing light, so that the light supplementing effect is matched with the light color temperature of the current shooting environment, the light supplementing effect is effectively improved, and the shooting requirement of a user is met.

In some embodiments of the present application, the color information may include a first hue value, a first saturation value, and a first lightness value corresponding to the first position, and the fill-in parameter may include a hue parameter, a saturation parameter, and a lightness parameter.

Fig. 3 is a flowchart illustrating another light supplement method according to an embodiment of the present disclosure, where the step 130 determines a light supplement parameter according to color information corresponding to the first position, and may include steps 310 to 330 shown in fig. 3.

In step 310, the first color value is determined as a color parameter.

And 320, determining a saturation parameter according to the first saturation value and a first preset threshold value.

The range of the first saturation value may be [0, 100], and the first preset threshold may be set according to specific requirements, which is not specifically limited herein.

For example, the first preset threshold may be 40, 42, etc.

Step 330, determining a brightness parameter according to the first brightness value and a second preset threshold value.

The range of the first brightness value may be [0, 100], and the second preset threshold may be set according to specific requirements, which is not specifically limited herein.

It should be noted that the execution sequence of the steps 310 to 330 is only an example, the

steps

320 and 330 may be before the step 310, or after the step 310, the step 320 may be before the step 330, or after the step 330, and the present application does not specifically limit the execution sequence of the

steps

310, 320, and 330.

In the embodiment of the application, when the electronic device receives a first input of a user to a first position in the shooting preview interface, in response to the first input, a first hue value, a first saturation value and a first brightness value of a display color of the first position in the shooting preview interface can be acquired. Based on this, the electronic device may determine that the first color value is a color parameter, and flexibly adjust based on a preset threshold value on the basis of the first saturation value and the first brightness value to obtain a saturation parameter and a brightness parameter, and finally determine a light supplement parameter adapted to the current shooting environment light. When the light supplement lamp carries out light supplement according to the light supplement parameters, the light supplement color fed back out can be close to the light color temperature of the shooting environment, and the atmosphere light supplement requirements of users for shooting under dim light and complex light are met.

In one example, the first preset threshold S0 may be 40 and the first saturation value S1 may be 35. Since S1 < S0, the saturation parameter S2 may be one-half of 40, i.e., 20.

In another example, the first preset threshold S0 may be 40, the first value may be 20, and the first saturation value S1 may be 95. Since S1 > S0, the saturation parameter S2 may be the difference between 95 and 20, i.e., 75.

In this embodiment of the application, the electronic device determines that the saturation parameter is one half of a first preset threshold value when the first saturation value is less than or equal to the first preset threshold value, and determines that the saturation parameter is a difference value between the first saturation value and the one half of the first preset threshold value when the first saturation value is greater than the first preset threshold value. Therefore, the first saturation value can be flexibly adjusted according to the first preset threshold value, the saturation is properly reduced on the basis of the first saturation value, and the light supplement effect corresponding to the saturation parameter is ensured.

In one embodiment, step 330 may specifically include: determining the lightness parameter as the product of a second preset threshold value and a preset multiple under the condition that the first lightness value is greater than or equal to the second preset threshold value; and under the condition that the first brightness value is smaller than a second preset threshold value, determining the brightness parameter as the sum of the first brightness value and the second preset threshold value.

In one example, the second preset threshold B0 may be 50, the preset multiple may be 2, and the first brightness value B1 may be 95. Since B1 > B0, the lightness parameter B2 may be the product of B0 and a preset multiple, i.e., 100.

In another example, the second preset threshold B0 may be 50, the preset multiple may be 2, and the first brightness value B1 may be 45. Since B1 < B0, the lightness parameter B2 may be the sum of B0 and B1, i.e., 95.

In the embodiment of the application, the electronic device determines the lightness parameter to be the product of a second preset threshold and a preset multiple when the first lightness value is greater than or equal to the second preset threshold; and under the condition that the first brightness value is smaller than a second preset threshold value, determining the brightness parameter as the sum of the first brightness value and the second preset threshold value. Therefore, the first brightness value can be flexibly adjusted according to the second preset threshold value, the value of the brightness parameter in the light supplement parameter is ensured to be within a proper range, the phenomenon that the color of the light supplement lamp is too dark due to too low brightness can be avoided, the light supplement effect is ensured, and the light supplement requirement of a user is met.

Optionally, in one embodiment, the first preset threshold may range from 30 to 50, and the second preset threshold may range from 40 to 60.

In some embodiments of the present application, in order to further improve the light supplement effect, the shooting preview interface may include a first control.

In one embodiment, the fill-in parameter may include a brightness parameter, and the brightness parameter may be determined based on a brightness value of the shooting preview interface or a brightness value of a first position in the shooting preview interface.

Fig. 4 is a flowchart illustrating a further light supplement method according to an embodiment of the present disclosure, and as shown in fig. 4, after step 140, the method may further include steps 410 to 440.

At step 410, a second input to the first control is received.

The first control is used for triggering the electronic device to display the target information, and the second input may be click input, double-click input, slide input, long-press input, and the like of the user to the first control, which is not specifically limited herein.

In one example, as shown in fig. 5, the capture preview interface 501 may include a first control 502 and the second input may be a user click input to the first control 502.

And step 420, responding to the second input, and displaying the target information on the shooting preview interface.

The target information may include a fill-in light parameter and a second control, where the second control may be a control for adjusting the fill-in light parameter, and the fill-in light parameter may include a hue parameter, a saturation parameter, and a brightness parameter.

It should be noted that, since the fill-in light parameter may include a hue parameter, a saturation parameter, and a brightness parameter, the second control may include three sub-controls, and the three sub-controls are respectively used to adjust the hue parameter, the saturation parameter, and the brightness parameter.

In one example, the electronic device determines, according to the color information corresponding to the first position, a hue parameter, a saturation parameter, and a brightness parameter of the fill-in light parameters to be 210, 75, and 100, respectively. As shown in fig. 5, when the electronic device receives a user click input to the first control 502, a shooting preview interface 503 is displayed in response to the click input, and the shooting preview interface 503 may include target information. The target information may include the fill-in light parameter "210, 75, 100" and a second control 504, the second control 504 may include three sub-controls respectively used for adjusting the hue parameter, the saturation parameter, and the brightness parameter, and the user may adjust the fill-in light parameter "210, 75, 100" by sliding the three sub-controls.

Step 430, a third input to a second control in the target information is received.

The third input may be a click input, a long-press input, a sliding input, a dragging input of the second control by the user, or a combination of at least two of the above inputs, and the like, which is not specifically limited herein.

For example, as shown in fig. 5, the third input may include a long press input and a slide input by the user to a sub-control of the second control 504 that is used to adjust the hue parameter.

Step 440, responding to the third input, adjusting the light supplement parameter, and performing light supplement based on the adjusted light supplement parameter.

In one example, the electronic device determines, according to the color information corresponding to the first position, a hue parameter, a saturation parameter, and a brightness parameter of the fill-in light parameters to be 210, 75, and 100, respectively. The user may adjust the hue parameter to 220, the saturation parameter to 80, and the brightness parameter to 98 by sliding the second control. Therefore, the electronic device can control the fill-in light module, for example, control the fill-in light lamp to fill in light based on the fill-in light parameter "210, 75, 100".

In this embodiment of the application, after the electronic device controls the light supplement module to supplement light based on the light supplement parameter, if the light supplement effect does not meet the user expectation, the user may trigger the electronic device to display the light supplement parameter and the second control through the input to the first control. On this basis, the user can continue to adjust on the basis of the light filling parameter through operating the second control to make final light filling effect can reach user's expectation, promote the degree of freedom of light filling parameter adjustment.

In some embodiments of the present application, to simplify user operations, the capture preview interface may include at least one color chip.

Each color card may be associated with a hue parameter, a saturation parameter, and a brightness parameter, where at least one of the hue parameter, the saturation parameter, and the brightness parameter associated with different color cards is different.

Illustratively, as shown in fig. 7, the shooting preview interface 701 may include a color chart 702, a color chart 703, and a color chart 704, wherein the hue parameter H, the saturation parameter S, and the lightness parameter B associated with the three color charts are all different.

In one embodiment, the color information corresponding to the first position may include a first hue value, a first saturation value, and a first lightness value, and the at least one color chip may include a first color chip and a second color chip. Prior to step 610, the method may further comprise: determining that the light supplement parameters associated with the first color card comprise a first color tone value, a first saturation value and a first brightness value; adjusting at least one of the first hue value, the first saturation value and the first lightness value based on a preset value; and determining a second color card according to the adjusted first color tone value, the adjusted first saturation value and the adjusted first brightness value.

The second color card may include at least one.

In one example, the first hue value, the first saturation value, and the first lightness value are 210, 95, and 95, respectively, then the hue parameter H, the saturation parameter S, and the lightness parameter B associated with the first color card may be determined to be 210, 95, and 95, respectively. The preset value may include 5 and 10, and optionally, the preset value 10 may be added to the first color value to obtain the hue parameter 220, the saturation parameter 95 and the lightness parameter 95 associated with the second color card a 1; a preset value of 5 may be added on the basis of the first color value and the first saturation value, respectively, to obtain a color parameter 215, a saturation parameter 100, and a brightness parameter 95 associated with the second color card a 2; the preset value of 5 may be reduced based on the first hue value, the first saturation value and the first lightness value, respectively, to obtain the hue parameter 205, the saturation parameter 90 and the lightness parameter 90 associated with the second color card a 3.

Illustratively, when the electronic device receives a long press input for selecting the color target 704 in fig. 7 by the user, the electronic device may perform light supplement based on the light supplement parameter H ═ 205, S ═ 90, and B ═ 90 associated with the color target 704 in response to the long press input.

In this embodiment, the shooting preview interface may include at least one color chip, and since the fill-in light parameter associated with the color chip is determined based on the color information of the first position, the color chip is closer to the display color of the first position in the shooting preview interface. If the effect based on the light supplement parameter light supplement does not meet the user expectation, the user can select a favorite target color card from all color cards, and the electronic equipment can supplement light based on the light supplement parameter associated with the target color card, so that the light supplement color of the light supplement lamp is matched with the target color card, the free adjustment of the light supplement color is realized, and the operation is simple and convenient.
