[0023] Figure 1 is a flow chart of a method for adjusting screen parameters of an electronic device according to an exemplary embodiment. Figure 1 As shown, the screen parameter adjustment method of the electronic device of the embodiment of the present application includes but is not limited to the following steps:

[0024] S101, obtaining the light intensity of the environment in which the electronic device is currently located.

[0025] It should be noted that the execution subject of the screen parameter adjustment method of the electronic device provided in the embodiment of the present application is an electronic device, and the electronic device can be a terminal device. Optionally, the terminal device can be a mobile electronic device or a non-mobile electronic device.

[0027] Optionally, the light intensity may be monitored based on an ambient light sensor configured in the electronic device to obtain the light intensity of the environment in which the electronic device is currently located.

[0028] For example, the ambient light sensor can be called through the sensor management component (SensorManager) to monitor the light intensity, and the light intensity of the current environment of the electronic device can be returned through monitoring events.

[0029] It should be noted that after the light intensity is obtained, the light intensity level of the environment in which the electronic device is currently located can be obtained according to a preset light intensity threshold.

[0030] The light intensity level of the environment in which the electronic device is currently located includes but is not limited to strong light, normal light and weak light.

[0031] S102, obtaining the current screen usage time and screen display content type of the electronic device.

[0032] Among them, screen usage time is the cumulative time that the electronic device screen is turned on and off each time.

[0033] It should be noted that the present application does not limit the specific method for obtaining the current screen usage time of the electronic device, and it can be selected according to actual conditions.

[0034] Optionally, the screen usage time can be monitored based on a timer.

[0035] For example, a countdown timer (CountDownTimer) can be started or reset when the current screen of the electronic device is turned on, and the countdown timer can be turned off (timeout) when the screen is turned off to determine the current screen usage time of the electronic device.

[0036] Optionally, the screen usage time may be monitored based on a task scheduler (JobScheduler).

[0037] For example, a task for monitoring screen usage time may be created, and the task may be started through a task scheduler to monitor screen usage time.

[0038] It should be noted that the present application does not limit the specific method for obtaining the type of content currently displayed on the screen of the electronic device, and it can be selected according to actual conditions.

[0039] Optionally, the type of the current screen display content of the electronic device can be identified, and the type of the current screen display content of the electronic device, such as text, picture, video, etc., can be determined based on the user interface (UI) elements and element hierarchical relationships on the current screen.

[0040] S103, obtaining an eye image of the user collected by the electronic device, extracting eye feature data of the eye image of the user, and determining the current fatigue level of the user according to the eye feature data.

[0041] Optionally, based on a permission instruction for the image acquisition device enabled by the user, the user's eye images may be periodically acquired through the image acquisition device, wherein the image acquisition device may be a camera.

[0042] In an embodiment of the present application, after acquiring the eye image, feature extraction may be performed on the user's eye image to obtain eye feature data.

[0043] Optionally, feature extraction may be performed on the eye image based on a pre-trained eye feature extraction model to obtain eye feature data, wherein the eye feature data may be eyelid closure degree, eyelid closure frequency, and the like.

[0044] Optionally, a mapping relationship between the eye feature data and the fatigue level may be pre-constructed, and the user's current fatigue level may be determined by querying the mapping relationship based on the eye feature data.

[0045] It should be noted that fatigue levels include but are not limited to no fatigue, mild fatigue, moderate fatigue and severe fatigue.

[0046] S104, adjusting the screen font size and screen contrast of the electronic device according to the light intensity, screen usage time, screen display content type and the user's current fatigue level.

[0047] In an embodiment of the present application, after obtaining the light intensity, screen usage time, screen display content type and the user's current fatigue level, the light intensity, screen usage time and the user's current fatigue level can be standardized to obtain the light intensity parameter value W, the screen usage time parameter value T and the fatigue level parameter value F, and obtain a pre-built assignment strategy for the screen display content type, and determine the screen display content type parameter value S corresponding to the screen display content type according to the assignment strategy.

[0048] Optionally, a pre-constructed screen parameter adjustment condition set can be obtained, wherein the screen parameter adjustment set includes multiple screen parameter adjustment conditions, and it is determined whether the light intensity parameter value, the screen usage time parameter value, the fatigue level parameter value, and the screen display content type parameter value meet the screen parameter adjustment conditions. In response to meeting the screen parameter adjustment conditions, a first adjustment mode for the screen font size and a second adjustment mode for the screen contrast are determined according to the screen parameter adjustment conditions, and a first adjustment amplitude for the screen font size and a second adjustment amplitude for the screen contrast are determined according to the light intensity parameter value, the screen usage time parameter value, the screen display content type parameter value, and the fatigue level parameter value. According to the first adjustment mode and the first adjustment amplitude, the current screen font size of the electronic device is adjusted, and according to the second adjustment mode and the second adjustment amplitude, the current screen contrast of the electronic device is adjusted.

[0049] The first adjustment mode of the screen font size is to maintain the screen font size, increase the screen font size, or decrease the screen font size.

[0050] Among them, the second adjustment mode of the screen contrast is to maintain the screen contrast, increase the screen contrast, and reduce the screen contrast.

[0051] For example, if the first adjustment mode of the screen font size is to increase the screen font size and the first adjustment range is 10%, then the screen font size of the electronic device will be increased by 10% on the original basis; if the second adjustment mode of the screen contrast is to reduce the screen contrast and the second adjustment range is 15%, then the screen font size of the electronic device will be reduced by 10% on the original basis.

[0052] In the screen parameter adjustment method of an electronic device provided in an embodiment of the present application, by obtaining the light intensity of the current environment of the electronic device, obtaining the current screen usage time and the screen display content type of the electronic device, obtaining the user's eye image collected by the electronic device, and extracting the eye feature data of the user's eye image, the user's current fatigue level is determined according to the eye feature data, and the screen font size and screen contrast of the electronic device are adjusted according to the light intensity, screen usage time, screen display content type and the user's current fatigue level. Therefore, the present application can comprehensively and dynamically adjust the screen font size and screen contrast of the electronic device according to the light intensity, screen usage time, screen display content type and the user's current fatigue level, which can significantly improve the user's visual experience and improve the automation and intelligence levels of screen parameter adjustment.

[0053] As a possible implementation, Figure 2 As shown, based on the above embodiment, the specific process of adjusting the screen font size and screen contrast of the electronic device according to the light intensity, screen usage time, screen display content type and the user's current fatigue level includes the following steps:

[0054] S201, obtaining a pre-built screen parameter adjustment condition set, wherein the screen parameter adjustment set includes a plurality of screen parameter adjustment conditions.

[0055] It should be noted that the present application does not limit the setting of the screen parameter adjustment conditions, which can be set according to actual conditions.

[0056] Optionally, screen parameter adjustment condition 1 is that the light intensity is weak and the user's current fatigue level is mild fatigue.

[0057] Optionally, screen parameter adjustment condition 2 is that the light intensity is normal light, the user's current fatigue level is not fatigued, and the screen display content type is text.

[0058] S202, determining whether the illumination intensity parameter value, the screen usage time parameter value, the fatigue level parameter value, and the screen display content type parameter value meet the screen parameter adjustment conditions.

[0059] In an embodiment of the present application, after obtaining the pre-constructed screen parameter adjustment conditions, it can be determined whether the light intensity parameter value, screen usage time parameter value, fatigue level parameter value and screen display content type parameter value meet the screen parameter adjustment conditions.

[0060] S203: In response to the screen parameter adjustment condition being met, determining a first adjustment mode for the screen font size and a second adjustment mode for the screen contrast according to the screen parameter adjustment condition.

[0061] Each screen parameter adjustment condition corresponds to an adjustment mode of screen font size and a adjustment mode of screen contrast.

[0062] For example, for screen parameter adjustment condition 1, that is, the light intensity is weak and the user's current fatigue level is mild fatigue, in this case, the first adjustment mode of the screen font size is to increase the screen font size, and the second adjustment mode of the screen contrast is to reduce the screen contrast.

[0063] S204, determining a first adjustment range of the screen font size and a second adjustment range of the screen contrast according to the illumination intensity parameter value, the screen usage time parameter value, the screen display content type parameter value, and the fatigue level parameter value.

[0064] As a possible implementation, Figure 3 As shown, based on the above embodiment, according to the illumination intensity parameter value, the screen usage time parameter value, the screen display content type parameter value and the fatigue level parameter value, the specific process of determining the first adjustment range of the screen font size and the second adjustment range of the screen contrast includes the following steps:

[0065] S301, obtaining a pre-built weight distribution strategy.

[0066] It should be noted that the present application can dynamically adjust the priority of light intensity, screen usage time, screen display content type and user's current fatigue level according to the actual application scenario of the electronic device. The higher the priority, the greater the weight, thereby constructing a weight distribution strategy.

[0067] For example, if the light intensity of the environment in which the electronic device is currently located is weak light, the priority corresponding to the light intensity is higher, that is, the weight is larger; if the light intensity of the environment in which the electronic device is currently located is normal light, the priority corresponding to the user's fatigue level is higher, that is, the weight is larger.

[0068] S302, according to the weight allocation strategy, determine the first weight corresponding to the light intensity parameter value, the second weight corresponding to the screen usage time parameter value, the third weight corresponding to the screen display content type parameter value and the fourth weight corresponding to the fatigue level parameter value.

[0069] In an embodiment of the present application, after obtaining the weight allocation strategy, the first weight m1 corresponding to the light intensity parameter value, the second weight m2 corresponding to the screen usage time parameter value, the third weight m3 corresponding to the screen display content type parameter value, and the fourth weight m4 corresponding to the fatigue level parameter value can be determined according to the weight allocation strategy.

[0070] S303, performing weighted averaging processing on the illumination intensity parameter and the first weight, the screen usage time parameter value and the second weight, the screen display content type parameter value and the third weight, and the fatigue level parameter value and the fourth weight to obtain a weighted average result.

[0071] In the embodiment of the present application, the weighted average result can be obtained by the following formula:

[0072] y=W×m1+T×m2+F×m3+S×m4

[0073] Among them, y is the weighted average result, W is the light intensity parameter value, m1 is the first weight, T is the screen usage time parameter value, m2 is the second weight, F is the fatigue level parameter value, m3 is the third weight, the screen display content type parameter value S, and m4 is the fourth weight.

[0074] S304: Determine a first adjustment range according to the weighted average result and a preset first adjustment factor.

[0075] In the embodiment of the present application, after the weighted average result and the preset first adjustment factor a1 are obtained, the first adjustment amplitude r1 can be determined by the following formula:

[0076] r1=y×a1

[0077] Among them, r1 is the first adjustment range, y is the weighted average result, and a1 is the first adjustment factor.

[0078] S305: Determine a second adjustment range according to the weighted average result and a preset second adjustment factor.

[0079] In the embodiment of the present application, after the weighted average result and the preset first adjustment factor a2 are obtained, the second adjustment amplitude r2 can be determined by the following formula:

[0080] r2=y×a2

[0081] Among them, r2 is the second adjustment range, y is the weighted average result, and a2 is the second adjustment factor.

[0082] S205: adjusting the current screen font size of the electronic device according to the first adjustment mode and the first adjustment range, and adjusting the current screen contrast of the electronic device according to the second adjustment mode and the second adjustment range.

[0083] In an embodiment of the present application, in order to prevent excessive adjustments and reduce the user experience, a first adjustment amplitude threshold for the screen font size and a second adjustment amplitude threshold for the screen contrast may be preset.

[0084] It should be noted that the present application does not limit the setting of the first adjustment amplitude threshold and the second adjustment amplitude threshold. For example, the first adjustment amplitude threshold preset for the screen font size can be within an increase or decrease range of 50% (±50%), and the second adjustment amplitude threshold preset for the screen contrast can be within an increase or decrease range of 20% (±20%).

[0085] In an embodiment of the present application, it is determined whether the first adjustment amplitude is less than a first adjustment amplitude threshold preset for the screen font size and whether the second adjustment amplitude is less than a second adjustment amplitude threshold preset for the screen contrast. In response to the first adjustment amplitude being less than the first adjustment amplitude threshold, the current screen font size of the electronic device is adjusted according to the first adjustment mode and the first adjustment amplitude. In response to the second adjustment amplitude being less than the second adjustment amplitude threshold, the current screen contrast of the electronic device is adjusted according to the second adjustment mode and the second adjustment amplitude.

[0086] It should be noted that in order to improve the user's visual experience, the current screen font size of the electronic device and the current screen contrast of the sub-device can be smoothly adjusted. For example, the adjustment of the current screen font size of the electronic device and the current screen contrast of the sub-device can be divided into multiple steps for adjustment.

[0087] Optionally, based on the first adjustment amplitude, the first adjustment times of the screen font size and the first adjustment amount corresponding to the first adjustment times can be determined, and the current screen font size of the electronic device can be adjusted in sequence according to the first adjustment mode, the first adjustment times and the first adjustment amount corresponding to the first adjustment times.

[0088] For example, for the first adjustment mode, which is to increase the screen font size, if the first adjustment amplitude is 10%, and the first adjustment times of the screen font size is 5 times, then the first adjustment amount corresponding to the first adjustment times is 2%, and each adjustment amount is 2%. Through 5 adjustments, the screen font size is increased in sequence to complete the adjustment of the current screen font size of the electronic device.

[0089] It should be noted that, for increasing the screen font size in the first adjustment mode, the adjusted screen font size is: original screen font size × [1 + (y × a1]; for decreasing the screen font size in the first adjustment mode, the adjusted screen font size is: original screen font size × [1 - (y × a1)].

[0090] Optionally, based on the second adjustment amplitude, the second adjustment times of the screen contrast and the second adjustment amount corresponding to the second adjustment times can be determined, and the current screen contrast of the electronic device can be adjusted in sequence according to the second adjustment mode, the second adjustment times and the second adjustment amount corresponding to the second adjustment times.

[0091] For example, for the second adjustment mode, which is to reduce the screen contrast, if the second adjustment amplitude is 15%, and the second adjustment times of the screen contrast is 5 times, then the second adjustment amount corresponding to the second adjustment times is 3%, and each adjustment amount is 3%. Through 5 adjustments, the screen contrast is reduced in turn to complete the adjustment of the current screen contrast of the electronic device.

[0092] It should be noted that, for increasing the screen contrast in the second adjustment mode, the adjusted screen contrast is: original screen contrast × [1 + (y × a2]; for decreasing the screen contrast in the second adjustment mode, the adjusted screen contrast is: original screen contrast × [1 - (y × a2)].

[0093] In the screen parameter adjustment method of an electronic device provided in an embodiment of the present application, a pre-constructed screen parameter adjustment condition set is obtained, wherein the screen parameter adjustment set includes multiple screen parameter adjustment conditions, and it is determined whether the light intensity parameter value, the screen usage time parameter value, the fatigue level parameter value, and the screen display content type parameter value meet the screen parameter adjustment conditions. In response to meeting the screen parameter adjustment conditions, a first adjustment mode for the screen font size and a second adjustment mode for the screen contrast are determined according to the screen parameter adjustment conditions, a pre-constructed weight allocation strategy is obtained, and according to the weight allocation strategy, a first weight corresponding to the light intensity parameter value, a second weight corresponding to the screen usage time parameter value, a third weight corresponding to the screen display content type parameter value, and a fourth weight corresponding to the fatigue level parameter value are determined, and the light intensity parameter value and the first weight, the screen usage time parameter value and the second weight, the screen display content type parameter value and the third weight are determined. The weighted average of the value and the third weight, the fatigue level parameter value and the fourth weight is performed to obtain a weighted average result, and a first adjustment amplitude is determined according to the weighted average result and a preset first adjustment factor, and a second adjustment amplitude is determined according to the weighted average result and the preset second adjustment factor, and the current screen font size of the electronic device is adjusted according to the first adjustment mode and the first adjustment amplitude, and the current screen contrast of the electronic device is adjusted according to the second adjustment mode and the second adjustment amplitude. Therefore, the present application can make the screen suitable for different environments and usage scenarios by dynamically adjusting the screen font size and screen contrast, thereby improving the user's visual experience, and combined with the user's fatigue level, it can provide more personalized visual protection. The present application uses a simple and efficient algorithm to improve the intelligence and automation level of screen parameter adjustment without relying on large-scale computing resources, and has high practicality.
