In one embodiment, the matched beauty parameter obtained according to the user characteristic can be used as a first beauty parameter, the face characteristic is extracted from the image to be displayed, a second beauty parameter is determined according to the face characteristic, and the image to be displayed is beautified according to the first beauty parameter and the second beauty parameter. The electronic equipment can perform face detection according to the image to be displayed, acquire corresponding face characteristic parameters according to a face area obtained by the face detection, and automatically determine a set of beauty parameters according to the face characteristic parameters, wherein the beauty parameters are the second beauty parameters.
In one embodiment, the method further comprises the steps of obtaining a preset third beauty parameter, and performing beauty treatment on the image to be displayed according to one or two of the second beauty parameter and the third beauty parameter and the first beauty parameter. Wherein the third beauty parameter is a beauty parameter calculated according to the beauty parameters set by the user history. The electronic equipment can acquire that the user carries out manual beauty to the image in the time quantum that predetermines, and the beautiful face parameter of setting regards manually set's squint parameter as the learning object of third beautiful face parameter, and the beautiful face parameter according to manual setting in this time quantum that predetermines generates third beautiful face parameter. Optionally, each manually set beauty parameter may be weighted and averaged, and the weight of each manually set beauty parameter may be determined according to the setting time, and the earlier the time is, the smaller the corresponding weight is. A third beauty parameter can be obtained based on the weighted average calculation. The preset time period can be any time period within the last month or within three months.
In an embodiment, corresponding weights may be set for the first, second, and third beauty parameters, respectively, and the three sets of beauty parameters are weighted and averaged according to the weights, and the image to be displayed is beautified according to the weighted and averaged beauty parameters.
In one embodiment, whether the image to be displayed is an image which has been beautified can be detected, and if not, the image to be displayed can be beautified according to the beautification parameters according to the steps. If the image is an already-beautified image, the image before beautification corresponding to the image after beautification can be acquired, and the image before beautification is beautified according to the beautification parameters.
In an embodiment, when the image to be displayed is an image with a beautiful color, the image to be displayed may be subjected to a weakened beauty treatment according to the first beauty parameter and/or the third beauty parameter, so as to further improve flexibility of the beauty treatment on the image to be displayed.
And step 210, displaying the image after the beautifying processing.

Compared with the traditional method that the image to be displayed needs to be displayed firstly, and then the beauty parameter of the image to be displayed is beautified, the image display method can directly display the image after the beauty treatment without displaying the original image to be displayed, and improves the operation efficiency.
In one embodiment, the image to be displayed is an image in which image content has not been displayed on the electronic device, i.e., an image in an unshayed state. For example, the image to be displayed is an image displayed in a list or a graph form, so that the user cannot refer to the content on the image. When a display instruction for the image is detected, the image can be beautified according to the above steps, so that the beautified image is displayed. For example, if the image includes an original face, the image is finally displayed as a face after beauty treatment instead of the original face when the image is displayed, so that the user can be prevented from directly viewing the image before beauty, and the privacy of the user is protected.
In one embodiment, step 206 includes: inquiring the user category to which the user belongs according to the user characteristics; and acquiring beauty parameters matched with the user category.
The electronic device presets a plurality of user categories. Alternatively, the user category may be a category divided according to one or more parameters of age, gender, race, and the like. User populations of different ages, genders and/or races are divided into a plurality of different user categories.

Because the brightness of the field environment is not always the same at different times, the electronic device can further set the beauty parameters matched with different user characteristics for different times. Alternatively, beauty parameters matching different user characteristics may be set for different time periods. The time period can be divided into time periods according to each day, for example, 5 time periods of 0:00 to-8: 00, 8:00 to 10:00, 10:00 to 15:00, 15:00 to 18:00 and 18:00 to 24:00 can be preset, and according to different time periods, beauty parameters matched with different user types are set. The electronic equipment can detect the time period to which the system time belongs according to the system time corresponding to the display instruction, and further inquire the beauty parameters matched with the user characteristics from all the beauty parameters matched with the time period.
In one embodiment, obtaining beauty parameters matching the system time and the user characteristics comprises: acquiring the brightness of the system at the system time; from all beauty parameters matching the brightness, a beauty parameter matching the user's feature is queried.
The electronic equipment can further set beauty parameters matched with different brightness. The brightness represents the brightness of the environment in which the electronic device is located. The electronic device may preset a plurality of brightness ranges, each brightness range matching a plurality of beauty parameters. According to the system time, the ambient brightness of the electronic equipment in the system time is detected, all beauty parameters matched with the ambient brightness are inquired, and beauty parameters matched with the user characteristics of a user viewing the image to be displayed are inquired and obtained from the beauty parameters. By setting the matching beauty parameter according to the brightness, the beauty process is further matched with the brightness.
In this embodiment, by introducing the system time, the beauty parameters matched with the user characteristics are not necessarily the same at different system times, so that the beauty effects of the same image viewed by the same user are also different at different times, and the flexibility of the beauty processing of the image to be displayed can be improved.
In one embodiment, before receiving a display instruction of an image to be displayed, the method further comprises: acquiring historical beauty parameters of the user on the image aiming at each user; and generating a beauty parameter matched with the user characteristic of the corresponding user according to the historical beauty parameter.
The electronic equipment can record the characteristic parameters of each user using the equipment in advance, record the beautifying parameters used in the process of beautifying the image by the user before, and take the parameters as the historical beautifying parameters of the corresponding user. For each user, all of their historical beauty parameters may be processed to generate beauty parameters that match the user's user characteristics. Optionally, the historical beauty parameters of the same user may be subjected to weighted average processing, and the obtained weighted average beauty parameter is used as the beauty parameter matched with the user characteristic of the user. Further, the weight value of each historical beauty parameter can be determined according to the generation time of the corresponding historical beauty parameter, and the earlier the generation time is, the smaller the corresponding weight value is.
By generating the beauty parameter matched with each user according to the historical beauty parameter of the user, the matching degree of the adopted beauty parameter and the user can be further improved.
In one embodiment, before step 206, the method further includes: acquiring the image type of an image to be displayed; step 206 comprises: inquiring various beauty parameters matched with the image types; and acquiring a beauty parameter matched with the user characteristic from the plurality of beauty parameters.
