Optionally, the cosmetic mirror 200b configures the received light source parameters into a target light source mode, which may be one of the user-selectable light source modes.

For example, the smartphone 200a sends the light source parameter of the target environment a to the cosmetic mirror 200b, and the cosmetic mirror 200b configures the light source parameter into the light source mode a and stores the light source mode a in the memory; the smart phone 200a sends the light source parameter of the target environment B to the cosmetic mirror 200B, and the cosmetic mirror 200B configures the light source parameter into the light source mode B and stores the light source mode B in the memory, so that the user can select between the light source modes a and B, and the light emitting module 210 generates a corresponding light source.

It should be understood that, for the light source parameters of the target environments a and B, the smart device 200a may transmit the light source parameters at one time or transmit the light source parameters separately, which is not limited in this embodiment of the application.

In one possible implementation manner, when the light source mode a is displayed on the display screen 220, the cosmetic mirror 200b takes the mode a as a default mode and controls the light emitting module 210 to generate a corresponding light source.

In another possible implementation manner, when the light source pattern a is displayed on the display screen 220, the user may control the light-emitting module 210 to generate the corresponding light source by clicking a prompt box on the display screen, or store the light source pattern a in the memory of the cosmetic mirror 200b as one of the light source patterns selectable by the user in response to the user's active triggering operation.

Optionally, a control App corresponding to the cosmetic mirror 200b is installed in the smartphone, and the user can perform corresponding operations in the App to enable the smartphone 200a to collect light source parameters of the target environment a and send the light source parameters to the cosmetic mirror 200b, so that the user can control whether the light source mode a takes effect in the App.

Exemplarily, the smartphone 200a sends the light source parameter to the cosmetic mirror 200b, and the cosmetic mirror 200b configures the light source parameter to be the light source mode a, so that the user can actively trigger on his App to enable the light source mode a to take effect, that is, the cosmetic mirror 200b generates the light source corresponding to the light source mode a. Or the cosmetic mirror 200b stores the light source pattern a in a memory as one of the user-selectable light source patterns according to the user's operation in App.

Optionally, a control App corresponding to the cosmetic mirror is installed in the smartphone 200a, and a user can perform corresponding operations in the App to enable the smartphone 200a to acquire light source parameters of one or more target environments, store the light source parameters of the one or more target environments in the smartphone, and send the light source parameters of the one or more target environments to the cosmetic mirror 200b when needed, and the cosmetic mirror 200b configures the light source parameters of the one or more target environments into one or more light source modes and generates a corresponding light source according to the selection of the user.

Optionally, the cosmetic mirror 200b may further include a camera (not shown in the figure), and after the cosmetic mirror generates the light source desired by the user, due to the influence of the ambient light in the environment where the cosmetic mirror 200b is currently located, a certain deviation between the light source in the current environment and the light source ideal by the user may occur. At this time, the cosmetic mirror can acquire the picture and/or video in the current environment through the camera, perform light source estimation to obtain light source parameters in the current environment, and compare the light source parameters with the light source parameters in the target environment. If the light source parameter under the current environment and the light source parameter of the target environment do not meet the preset condition, the current light source is kept, and if the light source parameter under the current environment and the light source parameter of the target environment meet the preset condition, the target light source is adjusted until the preset condition is not met.

In the embodiment of the application, the user only needs to send the picture, the video or the light source parameter of the target environment to the cosmetic mirror, the cosmetic mirror can automatically generate the light source in the target scene expected by the user, the light source is generated according to the target environment, therefore, the light source has higher similarity with the light source of the target environment, manual adjustment of the user is not needed, and the user experience is improved.

As shown in fig. 4 (b), due to the influence of the ambient light, the color temperature value of the light emitted from the light emitting module 210 of the cosmetic mirror 200b is actually different from 4000K set by the user. For example, when the light source of the light source emitted by the light emitting module 210 according to the user's intention is 4000K, the actual color temperature value in the environment may be 3800K only due to the influence of the ambient light. Therefore, in order to eliminate the influence of the ambient light on the cosmetic mirror, the color temperature value of the light source emitted by the light emitting module 210 may need to be 4200K, so that the actual color temperature value in the environment reaches 4000K desired by the user.

Optionally, the cosmetic mirror 200b may collect a photo or a video under the current light source (4000K) through a camera (not shown in the figure) of the cosmetic mirror 200b, and estimate an actual color temperature value under the environment, and if the actual color temperature value is not 4000K, the cosmetic mirror 200b may adjust the light-emitting module 210 to increase or decrease the color temperature value of the light source emitted by the light-emitting module until the actual color temperature value under the current environment is 4000K or a difference value between the actual color temperature value and 4000K is within a preset range.

208, the second electronic device adjusts the target light source when determining that the third light source parameter and the first light source parameter satisfy a preset condition.

Illustratively, the second electronic device obtains values of the color temperature/spectral distribution density/light intensity/light source model of the third light source parameter and the first light source parameter, and calculates a difference between the two sets of color temperature/spectral distribution density/light intensity/light source model.

Alternatively, the second electronic device searches for reference objects from the target light source and the target environment respectively, and compares the similarity between the reference objects, for example, if two groups of pictures both take the same object/person, the similarity estimation can be performed by using an image similarity matching algorithm.

Wherein, a threshold value can be set for the difference between the two groups of light source parameters, and a threshold value can also be set for the similarity of the same object/human body in the two images.

For example, if the difference M between the two sets of data color temperature values is greater than a first preset value, the current light source is considered to satisfy a preset condition. For example, M >100K, K being the thermodynamic temperature scale unit kelvin.

Or, if the two groups of data color temperature values are M1 and M2 respectively,

M_maxthe larger value of M1 and M2, the current light source is considered to satisfy the preset condition.

Or, if the similarity N of the same object/person in the two sets of data is less than or equal to a second preset value, for example, N >0.9, it is determined that the current light source satisfies the preset condition.

In the technical scheme, the second electronic equipment automatically adjusts the target light source when the target light source meets the preset conditions, so that the accuracy of the target light source can be improved, manual adjustment of a user is not needed, and the user experience is favorably improved.

It should be understood that, reference may be made to step 203 for the manner in which the first electronic device sends the first multimedia file to the second electronic device, and details are not described herein for brevity.

303, the second electronic device determines the first light source parameter according to the first multimedia file.

This step may refer to the description in step 202, and is not described in detail.

The second electronic device generates a target light source according to the first light source parameter 304.

305, determining whether the target light source satisfies a preset condition.

This step may refer to the related description in step 208, and is not described in detail.

306, if the current light source meets the preset condition, adjusting the current light source, and repeating the step 305 until the current light source does not meet the preset condition; and if the current light source does not meet the preset condition, keeping the current light source.

The current light source may be adjusted by increasing or decreasing the color temperature or the brightness value of the current light source, so that the current light source is adjusted in a direction not meeting the preset condition.

Optionally, the second electronic device may adjust the current light source within a preset time range, for example, the preset adjustment time of the system is 30s, and in the 30s time, if all the light sources generated by the second electronic device can meet the preset condition, the light source closest to the preset condition may be selected as the final light source from the process of adjusting the light sources.

Based on the technical scheme, the first electronic equipment sends the target light source data to the second electronic equipment, the second electronic equipment can generate a light source according to the target light source data, the data of the current light source are collected through the camera of the second electronic equipment and compared with the target light source data, if the current light source data meet the preset conditions, the current light source is adjusted until the preset conditions are not met, and therefore the high similarity between the light source generated by the second electronic equipment and the light source of the target environment can be guaranteed, and the user experience is improved.

Fig. 9 is a flowchart illustrating a method for controlling a light source according to an embodiment of the present application. Fig. 4 may be referred to as a scenario in which the embodiment of the present application may be applied. As shown in fig. 9, the method may include steps 401 to 405.

The user inputs light source parameters of the target light source 401.

The user may manually set the light source parameters of the target light source on the touch screen 220 of the cosmetic mirror 200b, or the user may set the light source parameters of the target light source by means of a voice password.

Optionally, the cosmetic mirror 200b further includes a control button, the display screen is only used for displaying the light source parameter, and the user can adjust the light source parameter of the target light source through the control button.

It should be understood that the light source parameters may include one or more of the color temperature, the spectral distribution density, the light intensity, and the light source model, which are not limited in the embodiments of the present application.

For example, the light source parameter may be a color temperature value of the light source, and referring to fig. 4, the user sets the color temperature value of the light source to 4000K.

402, the cosmetic mirror 200b generates a light source according to the light source parameter of the target light source set by the user.

403, cosmetic mirror 200b collects parameters of the actual light source of the environment under the target light source.

The cosmetic mirror 200b can acquire a picture or a video under a target light source according to a camera carried by the cosmetic mirror, and obtain actual light source parameters under the environment according to the acquired picture or video.

Referring to fig. 4, when the light emitting module of the cosmetic mirror 200b generates a light source with a color temperature value of 4000K, the actual color temperature value under the current environment may have a certain difference from 4000K due to the influence of the ambient light. Therefore, if the light source of the cosmetic mirror 200b is not adjusted, the light source generated by the light emitting module 210 is applied to the face of the user, and there is a certain error from the cosmetic effect that the user wants to achieve.

For example, the user sets the color temperature value of the light source to 4000K, and when the cosmetic mirror 200b does not generate a light source, the light source of the current ambient light is too cold, so that when the cosmetic mirror 200b generates a light source of 4000K, the actual color temperature value in the current environment may be 3800K.

404, if the light source parameter of the target light source does not satisfy the preset condition, the cosmetic mirror 200b adjusts the current light source, and repeats step 403.

The preset condition may refer to the related description in step 304, and is not described again for brevity.

Illustratively, the preset condition is that a difference between an actual color temperature value of the current environment and a user set value satisfies M > 100K. For example, the cosmetic mirror 200b may control the light emitting module 210 to increase or decrease the color temperature value of the light source generated by the light emitting module, so that the actual color temperature value under the current environment and the color temperature value M set by the user are adjusted in a direction that does not satisfy the preset condition.

And 405, if the current light source does not meet the preset condition, keeping the current light source.

In step 404, the light source is adjusted by the cosmetic mirror 200b, so that the actual light source parameter in the current light source environment does not satisfy the preset condition, and the current light source is maintained.

Optionally, if in step 404, the cosmetic mirror 200b adjusts the light source within a preset time period, and the actual light source parameter in the current light source environment still satisfies the preset condition, the cosmetic mirror 200b may select the light source generated within the preset time period and closest to the preset condition as the final light source, or select the light source adjusted last as the final light source.

In the embodiment of the application, the cosmetic mirror generates the light source according to the target light source parameter set by the user, and gather the actual light source of the current environment through the camera that self carries, and compare with the light source parameter set by the user, if current light source data satisfies the preset condition, then adjust the current light source until not satisfying the preset condition, this technical scheme does not need a plurality of equipment to cooperate, the complexity of adjusting the light source has been reduced, furthermore, the influence of the environment light before the cosmetic mirror generates the light source can be got rid of to this technical scheme, the uniformity of the light source that this cosmetic mirror produced and the light source that the user set for has been guaranteed, user's experience has been promoted.
