Description

Technical Field

[0001] This disclosure relates to the field of terminal technology, and in particular to a screen color temperature adjustment method, device and storage medium. Background Technology

[0002] With the widespread use of mobile devices, people are spending increasingly more time using them. However, prolonged use of mobile devices can cause eye strain and harm eyesight. Among the factors that have a significant impact, short-wavelength blue light, screen brightness, and color temperature are particularly relevant. Short-wavelength blue light is related to both screen brightness and color temperature.

[0003] A significant difference between screen brightness and ambient brightness can easily lead to eye fatigue. Related technologies use adaptive screen brightness adjustment to reduce this adverse effect.

[0075] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0076] As mentioned above, a significant difference between screen brightness and ambient brightness can easily lead to eye fatigue. Related technologies use adaptive screen brightness adjustment to reduce this adverse effect on the eyes. However, even with the same screen brightness and a consistently constant screen color temperature, prolonged use of the screen under these conditions can also cause visual fatigue as the screen is used for extended periods and the displayed content changes.

[0077] In view of this, the present disclosure provides a screen color temperature adjustment method, which adjusts the screen color temperature by acquiring the first reflected brightness of the screen at a first moment, the second reflected brightness of the screen at a second moment, and the first moment and the second moment. The screen color temperature can be adaptively adjusted according to the intensity of the screen display and the usage time, thereby reducing the short-wave blue light radiation of the screen and alleviating the user's visual fatigue.

[0078] Figure 1 This is a flowchart illustrating a screen color temperature adjustment method according to an exemplary embodiment, such as... Figure 1 As shown, the method includes the following steps.

[0079] In step S11, the first reflected brightness of the outer screen is obtained at a first moment, and the second reflected brightness of the outer screen is obtained at a second moment.

[0080] In step S12, the color temperature of the screen is adjusted based on the first time point, the second time point, the first reflection brightness, and the second reflection brightness.

[0081] In this embodiment of the disclosure, the screen color temperature adjustment method can be applied to a terminal, which may include a mobile phone, tablet computer, personal computer, server, home terminal, power terminal, vehicle terminal, etc. The screen may be a display screen / operation screen of a terminal that can be used for display and operation. Figure 2 This is a schematic diagram of the screen structure, such as... Figure 2As shown, a screen can include an inner screen and an outer screen. The inner screen is mainly used to display images, while the outer screen is mainly used for touch and to protect the inner screen. During the use of a terminal with a screen, the inner screen emits light to display content; the brightness of this light can be denoted as S1 + S2. When light passes through the outer screen, the outer screen reflects a portion of the light back onto the inner screen, while the remaining light penetrates the outer screen. The brightness of the light reflected from the outer screen is denoted as S2, and the brightness of the light penetrating the outer screen is denoted as S1. The brightness S2 of the light reflected from the outer screen changes as the user views different content. In one example, when the user switches between different applications or views different images, the brightness S2 of the light reflected from the outer screen changes. However, when the user reads a novel or other text, the brightness S2 of the light reflected from the outer screen remains constant for a longer period. Therefore, the change in the brightness S2 of the light reflected from the outer screen can be used to characterize the user's attention to the content on the terminal, and the color temperature can be adjusted accordingly.

[0082] In this embodiment of the disclosure, a first reflected brightness of the outer screen can be obtained at a first moment, and a second reflected brightness of the outer screen can be obtained at a second moment. Based on the first moment, the second moment, the first reflected brightness, and the second reflected brightness, the color temperature of the screen can be adjusted.

[0083] The first moment can be the moment the user turns on the terminal and uses the screen, the moment the user manually adjusts the screen color temperature, or any other moment that can be used as an adjustment reference; there are no restrictions here. Starting from the first moment, the external screen reflection brightness can be periodically collected, and the current collection moment is the second moment.

[0084] By adopting the technical solution of this disclosure embodiment, the color temperature of the screen is adjusted by obtaining the first reflected brightness of the screen at a first moment, the second reflected brightness of the screen at a second moment, and the first moment and the second moment. The color temperature of the screen can be adaptively adjusted according to the intensity of the screen display and the usage time, thereby reducing the short-wave blue light radiation of the screen and alleviating the user's visual fatigue.

[0085] In this embodiment of the disclosure, adjusting the color temperature of the screen based on a first time moment, a second time moment, a first reflection brightness, and a second reflection brightness may include: adjusting the color temperature of the screen when it is determined that the time difference between the second time moment and the first time moment is greater than or equal to a preset time threshold, and the difference between the second reflection brightness and the first reflection brightness is less than or equal to a preset brightness change threshold.

[0086] In this embodiment, the first moment can be the moment when the user turns on the terminal and uses the screen, the moment when the user sets the screen color temperature, or any other moment that can be used as an adjustment reference; no limitation is made here. Starting from the first moment, the external screen reflection brightness can be periodically collected. In one example, starting from the first moment t1, the external screen reflection brightness S1 can be collected every time interval Δt. When the external screen reflection brightness S2 collected at the second moment t2 satisfies t2-t1≥t... th And S2-S1≤S th If the screen brightness remains constant for more than a preset time, the blue light radiation from the screen can cause eye fatigue. Therefore, the screen's color temperature can be adjusted to alleviate this fatigue. The preset time threshold is t. th It can be equal to or greater than the time interval Δt, with a preset brightness change threshold S. th It can be a very small value, or it can be 0.

[0087] In this embodiment of the disclosure, adjusting the screen's color temperature based on a first time point, a second time point, a first reflective brightness, and a second reflective brightness may further include: if the time difference between the second time point and the first time point is determined to be less than a preset time threshold, the screen's color temperature is not adjusted regardless of whether the difference between the second reflective brightness and the first reflective brightness is less than or equal to a preset brightness change threshold. In one example, when t2-t1... <t th At that time, regardless of whether the difference between S2 and S1 is greater than the preset brightness change threshold S... th Since the user is not viewing the screen at the same brightness for an extended period of time, there is no need to adjust the screen color temperature.

[0088] Figure 3 This is a flowchart illustrating a method for adjusting the color temperature of a screen according to an exemplary embodiment, such as... Figure 3 As shown, the method includes the following steps.

[0089] In step S31, the color temperature of the screen at the first moment is obtained.

[0090] In step S32, the first color temperature adjustment parameter is obtained.

[0091] The first color temperature adjustment parameter is a color temperature value determined based on the color temperature at the first moment and the preset minimum color temperature. The preset minimum color temperature can be the minimum value of the nominal color temperature or the minimum value that the screen color temperature can be set within the range of human eye comfort.

[0092] In step S33, the color temperature at the first moment is corrected according to the first color temperature adjustment parameter to obtain the color temperature at the second moment.

[0093] In step S34, the color temperature of the screen is adjusted to the color temperature at the second moment.

[0094] In this embodiment, the screen's color temperature C0 at a first moment can be obtained, and a first color temperature adjustment parameter ΔC1 can be obtained. The first color temperature adjustment parameter is a color temperature value determined based on the color temperature at the first moment and a preset minimum color temperature. In one example, if the screen's nominal color temperature range is 0-10, and the color temperature C0 at the first moment is 5, then the minimum color temperature can be determined to be 0, and the first color temperature adjustment parameter ΔC1 can be 5-0=5. Further, the first color temperature adjustment parameter can be adjusted according to the range of human eye comfort. For example, if the actual range of human eye comfort within the nominal color temperature range is 3-7, then the minimum color temperature can be determined to be 3, and the first color temperature adjustment parameter ΔC1 can be 5-3=2. It should be noted that, since the short-wavelength blue light radiation of warm light in the screen is less than that of cold light when the screen brightness remains constant, adjusting the screen's color temperature can be done by adjusting the color temperature towards warmer light, for example, by lowering the color temperature value.

[0095] In this embodiment, the color temperature at a first moment can be corrected based on the obtained first color temperature adjustment parameter to obtain the color temperature at a second moment. Furthermore, the color temperature at the second moment can be obtained based on the difference between the color temperature at the first moment and the first color temperature adjustment parameter. During correction, to avoid visual discomfort to the user caused by large color temperature abrupt changes, a continuous small-amplitude adjustment method can be used. In one example, starting from the second moment, the screen color temperature can be corrected once every first adjustment time ttmp1 to obtain a correction value Ctmp1 = C0 - (ΔC1 / n), and this correction value can be used as the screen color temperature. Here, n is the number of iterations for adjusting the screen color temperature. The value of n can be set; the smaller n is, the faster the color temperature adjustment and the greater the abrupt change in screen color temperature; the larger n is, the slower the color temperature adjustment and the smaller the abrupt change in screen color temperature.

[0096] In this embodiment of the disclosure, the method further includes: periodically acquiring the second reflected brightness starting from the second time point, and performing the step of adjusting the screen color temperature based on the first time point, the second time point, the first reflected brightness, and the second reflected brightness in each acquisition cycle. In one example, the external screen reflected brightness can be acquired periodically at the aforementioned time interval Δt, with the current acquisition time as the second time point and the previous acquisition time as the first time point. The aforementioned step of adjusting the screen color temperature based on the first time point, the second time point, the first reflected brightness, and the second reflected brightness can be performed in each acquisition cycle to achieve real-time adaptive adjustment of the screen color temperature.

[0097] In this embodiment of the disclosure, the method further includes, when it is determined that the time difference between the second moment and the first moment is greater than or equal to a preset time threshold, and the difference between the second reflective brightness and the first reflective brightness is greater than a preset brightness change threshold, the color temperature of the screen is called back to reduce the difference between the color temperature after the call-back and the color temperature at the first moment.

[0098] In this embodiment, the color temperature at the second moment can be slightly adjusted back to the color temperature at the third moment. Then, the slight adjustment step can be repeated multiple times when the color temperature adjustment condition is met, until the color temperature adjustment condition is no longer met, or the color temperature at the third moment is equal to the color temperature at the first moment. The color temperature adjustment condition includes that the time difference between the second moment and the first moment is greater than or equal to a preset time threshold, and the difference between the second reflection brightness and the first reflection brightness is greater than a preset brightness change threshold.

[0099] In this embodiment, when the time difference between the second moment and the first moment is greater than or equal to a preset time threshold, and the difference between the second reflected brightness and the first reflected brightness is greater than a preset brightness change threshold, it can be determined that the user has not been viewing a screen with the same brightness for a long time. In this case, there is no need to adjust the color temperature, and the color temperature can be reverted to the color temperature of the first moment, which is more familiar and suitable for the user. Here, the first moment can be the initial first moment, where the color temperature is user-defined or selected, or is the color temperature the user is accustomed to using.

[0100] Figure 4 This is a flowchart illustrating a method for adjusting the color temperature of a screen according to an exemplary embodiment, such as... Figure 4 As shown, the method includes the following steps.

[0101] In step S41, the color temperature of the screen at the second moment is obtained.

[0102] In step S42, the second color temperature adjustment parameter is obtained.

[0103] The second color temperature adjustment parameter is determined based at least on the difference between the color temperature at the current second moment and the color temperature at the first moment.

[0104] In step S43, the color temperature at the second moment is corrected according to the second color temperature adjustment parameter to obtain the color temperature at the third moment.

[0105] Among them, the difference between the third time and the second time is less than the preset time threshold, and the color temperature of the third time is less than the color temperature of the first time.

[0106] In step S44, the above steps of obtaining the color temperature at the second moment, obtaining the second color temperature adjustment parameter, and correcting the color temperature at the second moment according to the second color temperature adjustment parameter to obtain the color temperature at the third moment are repeated x times (i.e., steps S41, S42, and S43 are repeated x times) until the difference between the third moment and the second moment is greater than or equal to the preset time threshold, or the color temperature at the third moment is equal to the color temperature at the first moment.

[0107] Where x is a positive integer, and the product of x and the difference between the third time point and the second time point is less than or equal to the preset time threshold.

[0108] In this embodiment, the color temperature C2 of the screen at a second moment can be obtained, and the difference between the color temperature C2 at the second moment and the color temperature C0 of the screen at the first moment can be used as the second color temperature adjustment parameter ΔC2. It should be noted that the second moment here can be the current second moment, that is, the moment when the external screen reflection brightness was most recently collected, and the first moment here can be the initial first moment, that is, the moment when the external screen reflection brightness was first collected during this screen color temperature adjustment.

[0109] Similar to adjusting the screen's color temperature, to avoid visual discomfort caused by drastic changes in screen color temperature, continuous small adjustments can be used for correction during color temperature correction. In one example, starting from the second time step, the screen color temperature can be corrected once every second adjustment time step ttmp2 to obtain a correction value Ctmp2 = C2 - (ΔC2 / m), which is then used as the screen's color temperature. Here, m is the number of iterations for color temperature correction. The value of m needs to be set; the smaller m is, the faster the color temperature correction and the greater the sudden change in screen color temperature; the larger m is, the slower the color temperature correction and the smaller the sudden change in screen color temperature.

[0110] Furthermore, when adjusting the color temperature, the duration for which the screen brightness remains constant before the adjustment can be considered. If the duration is long, the impact of blue light radiation is greater. To improve user visual comfort during the adjustment, m can be set to a larger value to reduce the adjustment range. However, this may result in a slow adjustment speed, so the number of adjustments can be increased. In one example, an iteration coefficient x, a positive integer, can be set. The values ​​of x and m are set based on the duration for which the screen brightness remains constant before the color temperature adjustment. Before the difference between the third and second moments is greater than or equal to a preset time threshold, or before the color temperature at the third moment equals the color temperature at the first moment, the above steps of adjusting the screen color temperature are repeated x times. This can improve user visual comfort during screen color temperature adjustment.

[0111] Figure 5This is a flowchart illustrating a method for adjusting the color temperature of a screen according to an exemplary embodiment, wherein steps S51-S54 and Figure 4 Steps S41-S44 are the same and will not be repeated here. Figure 5 As shown, the method also includes the following steps.

[0112] In step S55, the time difference between the current second moment and the first moment, as well as the difference between the second reflection brightness and the first reflection brightness, are obtained in each judgment cycle.

[0113] The judgment period is one or more collection periods.

[0114] In step S56, when it is determined that the time difference between the current second moment and the first moment is greater than or equal to a preset time threshold, and the difference between the second reflection brightness and the first reflection brightness is greater than a preset brightness change threshold, the above steps of obtaining the color temperature of the second moment, obtaining the second color temperature adjustment parameter, and correcting the color temperature of the second moment according to the second color temperature adjustment parameter to obtain the color temperature of the third moment are repeated x times.

[0115] In step S57, when it is determined that the time difference between the current second moment and the first moment is greater than or equal to a preset time threshold, and the difference between the second reflective brightness and the first reflective brightness is less than or equal to a preset brightness change threshold, the step of adjusting the screen color temperature based on the first moment, the second moment, the first reflective brightness, and the second reflective brightness is executed.

[0116] In this embodiment of the disclosure, the judgment period can be one or more acquisition periods. That is, the terminal can make a judgment on whether to adjust the screen color temperature after each acquisition of the external screen reflection brightness, or it can make a judgment on whether to adjust the screen color temperature after each fixed acquisition of the external screen reflection brightness.

[0117] In this embodiment of the disclosure, when executing the screen color temperature callback method, the aforementioned step of callback the screen color temperature is iterated repeatedly in each judgment cycle. When it is determined that the screen does not meet the color temperature adjustment conditions, the step of callback the screen color temperature is continued in the next judgment cycle until the screen color temperature is callback to the color temperature at the first moment. When it is determined that the screen meets the color temperature adjustment conditions, the color temperature callback step is stopped and color temperature adjustment is performed instead.
