Summary of the invention

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0028] Embodiment 1

[0029] Figure 1 This is a flow chart of a display parameter adjustment method provided according to Embodiment 1 of the present invention. This embodiment is applicable to the case of adjusting the display parameters of a display device. The method can be executed by a display parameter adjustment device. The display parameter adjustment device can be implemented in the form of hardware and / or software. The display parameter adjustment device can be configured in an electronic device. The electronic device can be a device with a display device such as a mobile phone, a computer, and an intelligent electronic whiteboard. The display device can be considered as a device with a display function, such as a display.

[0030] like Figure 1 As shown, the method includes:

[0031] S110: Obtain current time information.

[0032] The current time may be the current moment when the display parameter is adjusted. The time information may be information representing the time. The time may be the system time of the electronic device or the network standard time, which is not limited here. The system time may be the time displayed by the electronic device. The network standard time is an Internet time protocol used to synchronize the time of computer systems in a network.

[0033] In one embodiment, this step may obtain the system time of the electronic device as the current time information; this step may also obtain the network standard time through the network as the current time information.

[0034] S120: Determine display parameters corresponding to the time information in the mapping relationship.

[0035] The mapping relationship indicates the display parameters corresponding to each time at multiple times, and the display parameters corresponding to each time are determined based on the reference circadian stimulation value corresponding to the time, and the display parameters include color temperature and brightness. The reference circadian stimulation value can be a circadian stimulation value used as a reference. The circadian stimulation value can be a measurement of the type of light required to affect human biochemistry. The circadian stimulation value can be determined based on the circadian illumination. The circadian illumination can be the spectral sensitivity weighted irradiance of the retinal conversion mechanism that stimulates the biological clock response. The response of the circadian system to different amounts of day and night light, the threshold circadian stimulation value is 0.1 to saturation 0.7. In the present invention, the threshold circadian stimulation value is ≥0.3 within at least two hours in the morning or afternoon, and the threshold circadian stimulation value at night is ≤0.1. In addition, ambient lighting and self-luminous displays need to be considered.

[0036] The mapping relationship may indicate the relationship between time and display parameters. Time and display parameters may be associated by reference to circadian rhythm stimulus values. Different times may correspond to different reference circadian rhythm stimulus values. Different reference circadian rhythm stimulus values ​​may correspond to different display parameters. The display parameters are determined by the relationship between time and reference circadian rhythm stimulus values, so that the determined display parameters conform to the circadian rhythm. The circadian rhythm aligns sleep and wakefulness with day and night, creating a stable restorative rest cycle, thereby increasing daytime activities. The mapping relationship enables the display device to be dynamically set according to the circadian rhythm law to simulate the changes in light intensity and color of natural light. At dawn: natural light is warm white and low intensity, then the color temperature and intensity gradually increase, and then the light reaches high brightness and cool white at noon (blue light produces biological effects and stimulates activity), and begins to change color and intensity again. Before sunset in the evening, it reaches low intensity and warm white light again (red light produces a relaxing effect).

[0037] After determining the time information, this step can query the mapping relationship to determine the display parameters corresponding to the time information. Exemplarily, the mapping relationship includes multiple moments or multiple time periods in 24 hours. Each moment or each time period corresponds to a display parameter. This step can determine the moment or time period that matches the time information and the mapping relationship, and then determine the display parameters of the matched moment or time period as the display parameters corresponding to the time information.

[0038] Table 1 is a mapping relationship table provided by an embodiment of the present invention. Referring to Table 1, the mapping relationship shows the color temperature and brightness corresponding to each hour within 24 hours of a day. For example, the color temperature corresponding to 7 o'clock is 5000, and the brightness is 150. The circadian rhythm stimulation value corresponding to 7 o'clock, also known as the reference circadian rhythm stimulation value, is 0.35. The circadian rhythm stimulation value is affected by color temperature and brightness, so the mapping relationship in the present invention is the mapping of time and display parameters (color temperature and brightness).

[0039] Table 1 A mapping relationship table provided by an embodiment of the present invention

[0040]

[0041] In an example, if the time information is 6 o'clock, it can be determined through the mapping relationship that the color temperature corresponding to 6 o'clock is 4000 and the brightness is 150.

[0042] Table 1 only shows the mapping between 24 time points and display parameters. The specific display parameters corresponding to the time between the time points can be set according to actual conditions. For example, the time period between the time points can correspond to the display parameters of the previous time point or the next time point. The time period can also be divided, and different sub-time periods after division can correspond to the display parameters of different time points.

[0043] For example, taking 5 o'clock and 6 o'clock as an example, the display parameters of the time period between (5:00 6:00) can be the display parameters of 5 o'clock or the display parameters of 6 o'clock. The time period can also be divided into two sub-time periods (5:00 5:30) and (5:30 6:00), and the display parameters of the sub-time periods can be the same as the display parameters of the time points close in time, such as the display parameters of (5:005:30) can be the display parameters corresponding to 5 o'clock.

[0044] S130: Adjust the display device based on the display parameters.

[0045] After the display parameters are determined, the display device may be adjusted based on the determined display parameters so that the display parameters of the display device are the display parameters corresponding to the time information.

[0046] When the display parameters include color temperature, the color temperature can be adjusted by adjusting the red, green and blue values ​​of the display device. When the display parameters include brightness, the brightness value of the display device can be adjusted based on the included brightness.

[0047] The display parameter adjustment method provided in the embodiment of the present invention obtains the current time information; determines the display parameters corresponding to the time information in the mapping relationship, wherein the mapping relationship indicates the display parameters corresponding to each time under multiple times, and the display parameters corresponding to each time are determined based on the reference circadian rhythm stimulation value corresponding to the time, and the display parameters include color temperature and brightness; adjusts the display device based on the display parameters, thereby solving the technical problem that the brightness adjustment of the existing display device causes confusion in the user's circadian rhythm, and adjusts the display parameters of the display device through the display parameters determined by the circadian rhythm stimulation value of the corresponding time, so that the display of the display device is adapted to the circadian rhythm.

[0048] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0049] In one embodiment, adjusting the display device based on the display parameter includes:

[0050] adjusting the brightness of the display device based on the brightness;

[0051] Determining red, green and blue values ​​corresponding to the color temperature;

[0052] The red, green and blue values ​​of the display device are adjusted based on the red, green and blue values.

[0053] The red, green and blue values ​​are also called RGB values, which represent the colors of the three channels of red, green and blue. In this embodiment, the display device can meet the color temperature requirements by adjusting the red, green and blue values.

[0054] In this embodiment, the brightness of the display device can be adjusted to the brightness included in the display parameters. For example, if the brightness included in the display parameters is 5000, then in this embodiment, the brightness of the display device can be adjusted to 5000.

[0055] In this embodiment, when adjusting the color temperature of the display device, the corresponding red, green and blue values ​​may be determined based on the color temperature, and then the red, green and blue values ​​of the display device may be set to the determined red, green and blue values.

[0056] This embodiment does not limit how to determine the red, green and blue values ​​based on the color temperature. Exemplarily, this embodiment can determine the red, green and blue values ​​based on the formula of color temperature and red, green and blue values. The red, green and blue values ​​include red (R) value, green (G) value and blue (B) value, and the red value, green value and blue value can correspond to different formulas respectively. The color temperature in the formula can be an independent variable, and the determination of the red value, green value and blue value can be realized by substituting the color temperature into the corresponding formula.

[0057] The present invention sets different color temperature parameters in different time periods to form a mapping relationship, calculates the red value, green value and blue value according to a formula, and then updates and replaces the corresponding RGB values ​​into a matrix for switching.

[0058] In one embodiment, determining the red, green and blue values ​​corresponding to the color temperature includes:

[0059] Determine a green value among red, green and blue values ​​based on a first quadratic function with color temperature as an independent variable and the color temperature;

[0060] Determine a blue value among the red, green and blue values ​​based on a second quadratic function with the color temperature as an independent variable and the color temperature;

[0061] The red value among the red, green and blue values ​​is set to a set value;

[0062] The coefficients of the first quadratic function are different from the coefficients of the second quadratic function.

[0063] The first quadratic function can be considered as a quadratic function for determining the green value with the color temperature as an independent variable. The second quadratic function can be considered as a quadratic function for determining the blue value with the color temperature as an independent variable.

[0064] In one embodiment, the result obtained by substituting the color temperature into the first quadratic function is determined as the green value.

[0065] In one embodiment, the result obtained by substituting the color temperature into the second quadratic function is determined as the blue value.

[0066] The setting value is not limited here and can be 1.

[0067] In one embodiment, the formula corresponding to the red value may be: R=CCT^2*0+CCT*0+1.

[0068] This embodiment does not limit the specific functions of the first quadratic function and the second quadratic function.

[0069] The first quadratic function can be:

[0070] G=CCT^2*0.00000000962353339+CCT*0.000153045476+0.390782778.

[0071] Wherein, CCT is color temperature, and G is green value. The quadratic term coefficient, linear term coefficient and constant of the first quadratic function are not limited here.

[0072] The second quadratic function can be:

[0073] B = CCT^2*0.0000000189359041+CCT*0.000302412211. Wherein, B is the blue value. The quadratic term coefficient and the linear term coefficient of the second quadratic function are not limited here.

[0074] In one embodiment, the obtaining of current time information includes:

[0075] Get the current system time of the display device.

[0076] In this embodiment, the time information is the system time, and the display parameters of the display device are adjusted based on the system time.

[0077] In one embodiment, the user can turn on the circadian rhythm button of the display device so that the display device adjusts the display parameters using the display parameter adjustment method provided by the present invention, so that the display parameters of the display device conform to the circadian rhythm. When adjusting the display parameters, the display device, such as the time displayed on the screen, can be obtained as time information, and then the color temperature and brightness corresponding to the time information are determined, and the display device is adjusted based on the determined color temperature and brightness. The user can also adjust the screen display time, and the display device can change the color temperature and brightness of the screen according to the adjusted time, and output the final display effect.

[0078] Embodiment 2

[0079] Figure 2 FIG. 1 is a flow chart of another display parameter adjustment method provided according to Embodiment 2 of the present invention. This embodiment further includes an operation of re-calibrating the display parameters. Figure 2 As shown, the method includes:

[0080] S210: Obtain current time information.

[0081] S220: Determine the display parameters corresponding to the time information in the mapping relationship.

[0082] S230: Adjust the display device based on the display parameters.

[0083] S240: Determine an actual circadian rhythm stimulation value of the display device.

[0084] The actual circadian rhythm stimulation value can be considered as the actually measured circadian rhythm stimulation value. This step does not limit how to determine the actual circadian rhythm stimulation value. This step can determine the actual circadian rhythm stimulation value by the measured red, green, and blue values ​​and brightness values ​​of the display device; or it can determine the actual circadian rhythm stimulation value only by the measured red, green, and blue values.

[0085] The measured red, green and blue values ​​can be considered to be the red, green and blue values ​​determined by the actual measurement display device.

[0086] In one embodiment, the actual circadian rhythm stimulation value may be determined by setting a formula, and the independent variable of the setting formula is not limited and may be set according to actual conditions.

[0087] S250. Adjust the display parameter based on the magnitude relationship between the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value corresponding to the time information.

[0088] After determining the actual circadian rhythm stimulation value, the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value corresponding to the time information can be compared, and the display parameters can be adjusted based on the size relationship. When adjusting the display parameters based on the size relationship, the adjustment method can be determined based on the relationship between the circadian rhythm stimulation value and the display parameters.

[0089] In one embodiment, the display parameters can be adjusted when the actual circadian rhythm stimulation value is less than the reference circadian rhythm stimulation value, and the display parameters can be adjusted when the actual circadian rhythm stimulation value is greater than the reference circadian rhythm stimulation value; the display parameters can also be adjusted when the difference between the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value is greater than a set value.

[0090] In one embodiment, the circadian rhythm stimulation value is proportional to the color temperature in the display parameters, and the circadian rhythm stimulation value is proportional to the brightness in the display parameters.

[0091] The display parameter adjustment method provided in this embodiment further includes an operation of adjusting the display parameter based on the actual circadian rhythm stimulation value, so that the actual circadian rhythm stimulation value displayed by the display device is closer to the reference circadian rhythm stimulation value, thereby improving the display effect of the display device.

[0092] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0093] In one embodiment, adjusting the display parameter based on the magnitude relationship between the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value corresponding to the time information includes:

[0094] In the case where the difference between the reference circadian rhythm stimulation value corresponding to the time information and the actual circadian rhythm stimulation value is greater than a first set value, increasing the display parameter;

[0095] When the difference between the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value corresponding to the time information is greater than a second set value, the display parameter is reduced.

[0096] When the difference between the reference circadian stimulation value and the actual circadian rhythm stimulation value is greater than the first set value, it can be considered that the display parameters determined based on the mapping relationship fail to make the circadian stimulation value reach the reference circadian rhythm stimulation value, and the difference is large, so the display parameters can be increased to increase the actual circadian rhythm stimulation value.

[0097] When the difference between the actual circadian rhythm stimulation value and the reference circadian rhythm stimulation value is greater than the second set value, it can be considered that the display parameters determined based on the mapping relationship cause the circadian rhythm stimulation value to exceed the reference circadian rhythm value by a large amount, so the display parameters can be reduced to reduce the actual circadian rhythm stimulation value.

[0098] There is no limitation on the specific values ​​of the first set value and the second set value. The first set value and the second set value may be equal or unequal, and the specific values ​​may be determined based on actual conditions.

[0099] In one embodiment, increasing the display parameter may increase one or more of the color temperature and the brightness, and decreasing the display parameter may decrease one or more of the color temperature and the brightness.

[0100] In one embodiment, the brightness can be adjusted preferentially. The brightness can be adjusted in different steps each time. The step size of each adjustment can be the same or different, and can be determined based on the value of the brightness and the value of the adjacent brightness. The adjacent brightness can be the brightness in the mapping table that is adjacent to the brightness. Taking Table 1 as an example, at 7 o'clock, the color temperature can be 5000, the brightness is 150, and the actual circadian rhythm stimulation value can be 0.3, which is less than the reference circadian rhythm stimulation value of 0.35, so the brightness can be increased, and the brightness adjacent to the brightness of 150 is 200, so the step size of the adjustment can be determined based on the difference between 150 and 200.

[0101] When adjusting the brightness, the maximum brightness value of the display device may also be considered to ensure that the adjusted brightness is less than or equal to the maximum brightness value.

[0102] When adjusting the color temperature, the color temperature value of the previous moment can be considered, and the color temperature difference between the current moment and the previous moment is greater than the set color temperature threshold. For example, the color temperature at 12 o'clock is 6500. If you want to reduce the color temperature, you need to consider the color temperature of 6000 at 11 o'clock. The color temperature after adjustment at 12 o'clock must have a certain difference from the color temperature of 6000 at 11 o'clock. The value of the color temperature threshold is not limited here.

[0103] In one embodiment, determining the actual circadian rhythm stimulation value of the display device includes:

[0104] Determining measured red, green, and blue values ​​and brightness values ​​of the display device;

[0105] An actual circadian rhythm stimulation value of the display device is determined based on the measured red, green and blue values ​​and the brightness value.

[0106] The measured red, green and blue values ​​can be considered as the red, green and blue values ​​of the display device actually measured. The means for determining the measured red, green and blue values ​​is not limited here, and can be determined based on the spectral data of the display device. The brightness value can be the actual brightness value of the display device, which can be measured by a brightness meter or a spectral brightness meter. Among them, the brightness meter can be a metering instrument for measuring light and color. The spectral brightness meter can realize the measurement of spectral data and brightness.

[0107] In one embodiment, a spectral brightness meter can be used to measure the spectral data and brightness value of the display device. The measured spectral data and the spectral radiation values ​​of the light and dark vision and the retinal photosensitive nerve cells are weighted and summed to obtain the measured red, green and blue values. Then, the actual circadian rhythm stimulation value is determined by the measured red, green and blue values ​​and the brightness value.

[0108] In this embodiment, the measured red, green, and blue values ​​and the brightness value can be substituted into the formula to obtain the actual circadian rhythm stimulation value. The formula is not limited here.

[0109] In one embodiment, the determining the actual circadian rhythm stimulation value of the display device based on the measured red, green and blue values ​​and the brightness value includes: if the measured blue value of the measured red, green and blue values ​​is greater than the brightness value, substituting the measured red, green and blue values ​​and the brightness value into a set formula to obtain the actual circadian rhythm illumination of the display device; otherwise, determining the actual circadian rhythm illumination of the display device based on the measured green value of the measured red, green and blue values;

[0110] Substitute the actual circadian stimulation illumination into a formula with the actual circadian stimulation illumination as an independent variable to obtain an actual circadian stimulation value.

[0111] The measured blue value may be a blue value obtained by actual measurement. When the measured blue value is greater than the brightness value, the measured red, green, and blue values ​​and the brightness value are substituted into the set formula to obtain the actual circadian illuminance. The set formula may be considered as a formula with the measured red, green, and blue values ​​and the brightness value as independent variables and the actual circadian illuminance as the dependent variable. The actual circadian illuminance may be considered as the circadian illuminance obtained by actual measurement.

[0112] In one embodiment, the setting formula may be:

[0113] CLA=1548*(G+0.7*(BY)-3.3*(1-exp(-R / 6.52))).

[0114] Among them, CLA can be the actual circadian rhythm stimulation value, the measured red value in the measured red value and blue value is R, the measured green value in the measured red, green and blue values ​​is G, and the measured blue value in the measured red, green and blue values ​​is B.

[0115] When the measured blue value is not greater than the brightness value, the actual circadian rhythm stimulation value can be determined based on the measured green value. The measured green value can be the green value actually measured. When the actual circadian rhythm stimulation value is determined based on the measured green value, it can be the product of the measured green value and the set value. The set value is not limited here.

[0116] CLA=If(B is greater than Y, 1548*(G+0.7*(BY)-3.3*(1-exp(-R / 6.52))), 1548*G).

[0117] Table 2 is a correspondence table of actual circadian rhythm illumination, actual circadian rhythm stimulation value, measured red, green and blue values, brightness value and measured spectral data provided by an embodiment of the present invention. Table 2 shows the measured red, green and blue values, brightness value, measured spectral data, actual circadian rhythm stimulation value and actual circadian rhythm illumination at each moment in 24 hours a day.
