The implementation of the respective data processing stages described above can be seen in the implementation shown in fig. 1 to 2.

Referring to fig. 1, fig. 1 is a flow chart illustrating a method for adjusting a screen display based on a micro-expression according to an embodiment of the present application. The method provided by the embodiment of the application can comprise the following steps 101 to 105:

101. and acquiring first micro-expression information in a user face image acquired at a first moment when the target user uses the terminal, and determining a target user age bracket corresponding to the first micro-expression information according to the age detection model.

In some possible embodiments, the facial features and pupil colors change to different extents as the user ages, wherein the facial features change mainly including facial shape changes and facial texture changes, such as growth of facial bones, changes in facial muscle elasticity, and wrinkles. During teenagers, facial features change mainly due to facial shape changes, and the influence of age on human faces is concentrated due to facial texture changes. The user face image in the process of using the terminal by the user can be acquired through the camera on the terminal or an external camera connected with the terminal, and the user face image at least comprises micro expression information. The micro-expression information includes facial texture information, eyebrow interval information, eye opening distance information, lip angle bending information, facial shape information, pupil color information and the like, and is specifically determined according to an actual application scene, and is not limited herein. Optionally, by analyzing the collected face image of the user, it may also be determined whether an eye shielding object exists on the face image of the user, where the eye shielding object includes myopia glasses, presbyopic glasses, sunglasses, and the like.

In some possible embodiments, a user face image corresponding to a first moment can be obtained by using a camera on the terminal or an external camera connected with the terminal to collect a user face image of a target user when the terminal is used at the first moment, wherein the user face image at the first moment at least comprises first micro-expression information, and the first micro-expression information comprises first face texture information, first eyebrow space information, first eye opening distance information, first lip angle bending information, face shape information, pupil color information and the like. The age detection model is used for acquiring first facial texture information and/or first eyebrow interval information and/or face shape information and/or pupil color information in the first micro-expression information of the target user, and inputting the first facial texture information and/or the first eyebrow interval information and/or face shape information and/or pupil color information into the age detection model, so that the age of the target user corresponding to the target user can be output based on the age detection model. The construction of the age detection model can comprise the data processing stages of modeling data acquisition of the age detection model, training of the age detection model, testing of the age detection model and the like. It is to be understood that the modeling data of the age detection model may be derived from facial feature information such as facial texture information and/or inter-eyebrow distance information and/or facial shape information and/or pupil color information of the same person in different age groups in the facial image database. Optionally, in order to enhance the prediction accuracy of the age detection model, the modeling data of the age detection model may also be derived from facial texture information and/or eyebrow spacing information and/or facial shape information and/or pupil color information of a large number of different people in different age groups in the facial image database. In training the age detection model, the user's age and facial feature information such as facial texture information and/or eyebrow space information and/or facial shape information and/or pupil color information corresponding to the user's age may be learned by the initial network model from the input information feature pair, and the user's age detection model corresponding to the user's age may be constructed by learning facial feature information such as facial texture information and/or eyebrow space information and/or facial shape information and/or pupil color information corresponding to the user's age and the input information feature pair. The facial feature information such as the user age, the facial texture information and/or the eyebrow distance information and/or the facial shape information and/or the pupil color information corresponding to the age may be facial feature information such as facial texture information and/or eyebrow distance information and/or facial shape information and/or pupil color information corresponding to the same person at different ages and different ages, or facial feature information such as facial texture information and/or eyebrow distance information and/or facial shape information and/or pupil color information corresponding to a large number of different persons. After the age detection model is built, facial texture information and/or eyebrow space information and/or facial shape information and/or pupil color information of any group of users with known ages can be collected as test data of the age detection model. And inputting the test data of each group into the constructed age detection model, comparing the user age output by the age detection model with the actual age of the user, if the age error between the user age output by the age detection model and the actual age of the user is smaller than the preset precision, indicating that the constructed age detection model meets the construction requirements, otherwise, indicating that the constructed age detection model does not meet the construction requirements, and continuing training the age detection model until the constructed age detection model meets the requirements.

102. And determining a target display list from the display lists according to the age range of the target user.

In some possible embodiments, as people age, the muscles in the skin of the human eye also weaken over time, so the requirements for screen display are different for different age groups. And as people age, the elasticity of facial muscles of people also becomes different, in other words, when people of different ages feedback on facial muscles on the same emotion, the degree of change of facial muscles is also different, namely the micro-expression change amount is different. Therefore, a display list corresponding to each age group of the age groups can be constructed, wherein each display list comprises a plurality of micro-expression change amounts of the corresponding user age groups and screen display information corresponding to the micro-expression change amounts, and the screen display information comprises one or more of screen display font size, screen display brightness and screen display font spacing. Thus, a target display list may be determined from the plurality of display lists based on the determined age bracket of the target user.

For example, assume that the user age group includes a first age group, a second age group, and a third age group, wherein the user age of the first age group is between 10 and 35 years old. The user of the second age group is aged 36 to 59 years and the user of the third age group is aged 60 to 85 years. The display list corresponding to the first age stage is a first display list, the display list corresponding to the second age stage is a second display list, and the display list corresponding to the third age stage is a third display list. The first display list, the second display list and the third display list all comprise a plurality of micro-expression change amounts and screen display information corresponding to the micro-expression change amounts, and it is easy to understand that the micro-expression change amounts are different when people of different age groups feed back the same emotion on facial muscles, so that the screen display information corresponding to the micro-expression change amounts of the same degree in the first display list, the second display list and the third display list are also different. For example, assuming that the micro-expression change amounts are all 10%, the screen display information corresponding to 10% of the micro-expression change amounts in the first display list is the screen display font size, the screen display brightness and the screen display font spacing are all increased by 3%, the screen display information corresponding to 10% of the micro-expression change amounts in the second display list is the screen display font size, the screen display brightness and the screen display font spacing are all increased by 5%, and the screen display information corresponding to 10% of the micro-expression change amounts in the third display list is the screen display font size, the screen display brightness and the screen display font spacing are all increased by 8%.

Alternatively, in some possible embodiments, near vision refers to a near vision refractive error condition in which the eye's ability to recognize a distant target is reduced, while near vision is normal. Presbyopia is a physiological phenomenon, is not a pathological state and is not refractive error, is a visual problem which is necessarily caused after people walk into middle-aged and elderly people, and is one of signals of body aging. In general, the wearing group of the myopia glasses is teenagers or middle aged people, and the wearing group of the presbyopic glasses is the aged, but the internal factors of the two glasses are completely different although the two glasses are used for correcting the eyesight. Thus, by analyzing the collected user face image of the target user, it is also possible to determine whether an eye mask exists on the user face image of the target user, wherein the eye mask includes myopia glasses, presbyopic glasses, sunglasses (generally, sunglasses are distinguished from other glasses in that the sunglasses lenses are colored), and the like. If the glasses exist on the face image of the target user and the glasses lenses are not colored, the type of the glasses of the target user can be determined according to the determined age range of the target user, and then the eye health state of the target user is known. If the age group of the target user is the first age group and the user wears glasses, the glasses type is myopia glasses, and the target user is myopia; if the target user age group is the third age group and the user is wearing glasses, the glasses type is presbyopic glasses, indicating that the target user is presbyopic. Although myopia and/or presbyopia can be corrected by wearing respective glasses, in practice, the myopia and non-myopia people of the same user age group after wearing the myopia glasses, the vision gap between presbyopia and non-presbyopia people of the same user age group after wearing the presbyopia glasses, and the sensitivity of the eyes to the external environment (here, screen display information such as screen display font size, screen display brightness, screen display font spacing, etc.) are also different. Thus, in one display list corresponding to each user age group, different screen display information corresponding to the same micro-expression change amount under the glasses and glasses-free screening conditions can be set for whether the user wears the glasses.

For example, assume that a user age group includes a first age group, a second age group, and a third age group, wherein the user age of the first age group is between 10 and 35 years old. The user of the second age group is aged 36 to 59 years and the user of the third age group is aged 60 to 85 years. The display list corresponding to the first age stage is a first display list, the display list corresponding to the second age stage is a second display list, and the display list corresponding to the third age stage is a third display list. The first display list, the second display list and the third display list all comprise a plurality of micro-expression change amounts and screen display information corresponding to the micro-expression change amounts, and it is easy to understand that the micro-expression change amounts are different when people of different age groups feed back the same emotion on facial muscles, so that the screen display information corresponding to the micro-expression change amounts of the same degree in the first display list, the second display list and the third display list are different. For users of the same age group, the screen display information of the users wearing the glasses and the users not wearing the glasses of the same degree of the micro-expression change amounts should be different, so that the display list can also comprise different screen display information corresponding to the same degree of the micro-expression change amounts of the users wearing the glasses and the users not wearing the glasses. For example, assuming that the micro-expression change amounts are 10%, in the case that there is no glasses, the screen display information corresponding to the micro-expression change amount 10% in the first display list is the screen display font size, the screen display brightness, and the screen display font spacing are all increased by 3%, the screen display information corresponding to the micro-expression change amount 10% in the second display list is the screen display font size, the screen display brightness, and the screen display font spacing are all increased by 5%, and the screen display information corresponding to the micro-expression change amount 10% in the third display list is the screen display font size, the screen display brightness, and the screen display font spacing are all increased by 8%. In the case of glasses, the screen display information corresponding to 10% of the micro-expression change amount in the first display list is the size of the screen display fonts, the screen display brightness and the screen display font spacing are increased by 4%, the screen display information corresponding to 10% of the micro-expression change amount in the second display list is the size of the screen display fonts, the screen display brightness and the screen display font spacing are increased by 7%, and the screen display information corresponding to 10% of the micro-expression change amount in the third display list is the size of the screen display fonts, the screen display brightness and the screen display font spacing are increased by 11%.

Optionally, in some possible embodiments, the brightness of the surrounding environment where the user is located and the distance between the eyes of the user and the terminal display screen also affect the experience of the user on the screen display font size, the screen display brightness and the screen display font spacing of the current terminal, so that the ratio of the brightness of the surrounding environment where the user is located and/or the brightness of the surrounding environment and the screen display brightness of the terminal display screen and/or the detected distance value between the eyes of the user and the terminal display screen can be incorporated into each display list to form a screening condition, and different screen display information corresponding to the same micro-expression change amount under different conditions can be set.

103. And acquiring second micro-expression information in a user face image acquired at a second moment when the target user uses the terminal, and determining a first micro-expression change amount according to the first micro-expression information and the second micro-expression information.

In some possible embodiments, the user face image corresponding to the second moment can be obtained by using a camera on the terminal or an external camera connected with the terminal to collect the user face image of the target user when the terminal is used at the second moment, wherein the second moment is another moment after the first moment passes through the preset duration or any moment after the first moment, the user face image at the second moment at least comprises second micro-expression information, and the second micro-expression information comprises second face texture information, second eyebrow interval information, second eye opening distance information, second lip angle bending information, face shape information, pupil color information and the like. The first facial texture information change value can be obtained by acquiring second facial texture information in the second micro-expression information and comparing the second facial texture information with the first facial texture information in the first micro-expression information. And obtaining a first eyebrow interval information change value by obtaining second eyebrow interval information in the second micro-expression information and comparing the second eyebrow interval information with the first eyebrow interval information in the first micro-expression information. And obtaining a first eye opening distance information change value by acquiring second eye opening distance information in the second micro-expression information and comparing the second eye opening distance information with first eye opening distance information in the first micro-expression information. And obtaining a first lip angle bending information change value by acquiring second lip angle bending information in the second micro-expression information and comparing the second lip angle bending information with the first lip angle bending information in the first micro-expression information. And determining a first micro-expression change amount according to the first face texture information change value, the first eyebrow interval information change value, the first eye opening distance information change value and/or the first lip angle bending information change value. The first micro-expression change amount may be one or more of the above-mentioned first facial texture information change value, first eyebrow interval information change value, first eye opening distance information change value, or first lip angle bending information change value. For example, if only one of the four information change values is used as the first micro-expression change amount, the first micro-expression change amount may be the maximum value or the minimum value of the four information change values. If the first micro-expression change amount is determined according to the four information change values, namely the first facial texture information change value, the first eyebrow interval information change value, the first eye opening distance information change value and the first lip angle bending information change value, the first facial texture information change value, the first eyebrow interval information change value, the first eye opening distance information change value and the first lip angle bending information change value are multiplied by corresponding weight values respectively and then summed, the summed value is determined to be the first micro-expression change amount or the four information change values are directly summed, and the summed value is determined to be the first micro-expression change amount.

For example, assuming that the first facial texture information variation value, the first eyebrow spacing information variation value, the first eye opening distance information variation value, and the first lip angle bending information variation value are 5%,3%, and 1%, respectively, if only the maximum information variation value of the four information variation values is taken as the first micro-expression variation amount, the first micro-expression variation amount is 5%. If the first micro-expression change amount is determined according to the first face texture information change value, the first eyebrow spacing information change value, the first eye opening distance information change value and the first lip angle bending information change value at the same time, and the weight values of the first face texture information change value, the first eyebrow spacing information change value, the first eye opening distance information change value and the first lip angle bending information change value are 5/12,3/12 and 1/12 respectively, the weighted and summed values are 3.7%, namely the first micro-expression change amount is 3.7%.

104. And determining first screen display information corresponding to the first micro-expression change amount from the target display list according to the first micro-expression change amount.
