[0085] Figure 1A is an interactive schematic diagram illustrating a curve determination method according to an embodiment of the present disclosure. As shown in Figure 1A, the present disclosure relates to a curve determination method, which includes:
[0086] Step S1101: The terminal acquires the first brightness curve.
[0087] In some embodiments, the first brightness curve is an initial screen brightness adjustment curve. Alternatively, it can be understood as the first brightness curve being a standard PQ curve.
[0088] In some embodiments, m1 = 0.1593, m2 = 78.8438, c1 = 0.8359, c2 = 18.8516, c3 = 18.6875, and bit_code = bit_code. 1 / m2 The first brightness curve is then (max((bit_code-c1),0) / (c2-c3*bit_code)). 1 / m1 .
[0089] In step S1102, the terminal obtains at least three first parameter points from the first brightness curve.
[0090] In some embodiments, the first parameter point refers to the parameter point used to generate the second brightness curve. In some embodiments, the second brightness curve is determined based on at least three first parameter points in the first brightness curve.
[0091] In this embodiment of the disclosure, after obtaining at least three first parameter points from the first brightness curve, a curve can be determined based on these at least three first parameter points. It should be noted that the determined second brightness curve is associated with the first brightness curve, and the first brightness curve can be adjusted.
[0092] In the embodiments of this disclosure, parameter points can be determined in different ways. Each method of determining the first parameter point is described below.
[0093] The first type:
[0094] In some embodiments, the parameter point in the first brightness curve whose horizontal and vertical coordinates are both the current brightness value is determined as the first parameter point. In this embodiment of the present disclosure, the terminal can obtain the current brightness value and determine the parameter point corresponding to the current brightness value as the value of the horizontal and vertical coordinates as the first parameter point.
[0095] Optionally, the current brightness value is Real-time Brightness. Then the coordinates of the first parameter point are [Real-time Brightness, Real-time Brightness].
[0096] It should be noted that the first method of determining the parameter point can also be understood as the method of determining the first parameter point. That is, the first method is used to determine the first parameter point.
[0097] The second type:
[0098] In some embodiments, if the current brightness value is less than a first value, the parameter point in the first brightness curve with the first value as the horizontal axis and the current brightness value as the vertical axis is determined as the first parameter point.
[0099] Optionally, the first value may be agreed upon by the communication protocol, configured by the terminal, or configured in other ways; this embodiment of the present disclosure does not impose any limitations. For example, the first value may be 1000 nits, 1500 nits, or other values; this embodiment of the present disclosure does not impose any limitations.
[0100] In this embodiment of the disclosure, if it is determined that the current brightness value is less than the first value, it means that the current brightness value can be used as the value corresponding to the vertical axis, and the value of the horizontal axis is defined as the first value. Then, the parameter points corresponding to the horizontal and vertical axes are determined as the first parameter points.
[0101] For example, if Real-time Brightness < 1000 nits, then the x-axis is 1000 and the y-axis is Real-time Brightness.
[0102] In some embodiments, if the current brightness value is greater than or equal to the first value, the parameter point in the first brightness curve whose horizontal axis is the maximum brightness value of the terminal and whose vertical axis is the current brightness value is determined as the first parameter point.
[0103] Optionally, the maximum brightness value is determined by the terminal's hardware configuration, or by the communication protocol, or by the terminal configuration; this embodiment does not impose any limitations.
[0104] In this embodiment of the disclosure, if it is determined that the current brightness value is greater than or equal to the first value, it means that the current brightness value can be used as the value corresponding to the vertical axis, and the value of the horizontal axis is defined as the maximum brightness value. Then, the parameter points corresponding to the horizontal and vertical axes are determined as the first parameter points.
[0105] For example, the horizontal axis represents Panel Peak Luminance, and the vertical axis represents Real-time Brightness. Panel Peak Luminance is the maximum brightness value.
[0106] It should be noted that the second method of determining the parameter point can also be understood as the method of determining the second parameter point. That is, the second method is used to determine the second first parameter point.
[0107] The third type:
[0108] In some embodiments, if the current brightness value is greater than or equal to the second value, the parameter point in the first brightness curve whose horizontal and vertical coordinates are both the current brightness value is determined as the first parameter point. In this embodiment of the present disclosure, if it is determined that the current brightness value is greater than or equal to the second value, the parameter point whose horizontal and vertical coordinates are both the current brightness value is determined as the first parameter point.
[0109] For example, if Real-time Brightness >= 1000 nits, then both the x-axis and y-axis are Real-time Brightness.
[0110] In some embodiments, if the current brightness value is less than the second value, the parameter point in the first brightness curve whose horizontal and vertical coordinates are both the third value is determined as the first parameter value. The third value is the difference between the current brightness value and the fourth value, the fourth value is the product of the current brightness value and the fifth value, the fifth value is the difference between 1 and the sixth value, and the sixth value is the ratio of the current brightness value to the second value.
[0111] Optionally, the second value may be agreed upon by the communication protocol, configured by the terminal, or configured in other ways; this embodiment of the present disclosure does not impose any limitations. For example, the second value may be 1000 nits, 1500 nits, or other values; this embodiment of the present disclosure does not impose any limitations.
[0112] It should be noted that the first and second values in the embodiments of this disclosure may be equal or unequal, and this disclosure does not limit them.
[0113] For example, if Real-time Brightness < 1000 nits, then the x-axis and y-axis are Real-time Brightness - Real-time Brightness * (1 - Real-time Brightness / 1000).
[0114] It should be noted that the third method of determining the parameter point can also be understood as a method of determining the third parameter point. That is, the third method is used to determine the third first parameter point.
[0115] The following example illustrates how to determine at least three first parameter points. For instance, if Real-time Brightness = 500 nits and Panel Peak Luminance = 1400 nits, then the first parameter point determined using the first method is P1[500, 500], the first parameter point determined using the second method is P2[1000, 500], and the parameter point determined using the third method is P0[250, 250]. For example, as shown in Figure 1B, the vertical axis of the first brightness curve has a maximum value.
[0116] In step S1103, the terminal determines the second brightness curve based on at least three first parameter points.
[0117] In some embodiments, steps S1102-S1103 refer to the steps of the terminal acquiring the second brightness curve.
[0118] In some embodiments, a Bézier curve is drawn based on at least three first parameter points.
[0119] In some embodiments, the second luminance curve is determined using the following formula:
[0120] B(t)=(1-t) 2 *P0+2t*(1-t)*P1+t 2 *P2,t∈[0,1], where P0, P1 and P2 are the first parameter points, and t is a real number.
[0121] For example, referring to Figure 1C, if P0, P1, and P2 are as shown in the example above, the second brightness curve drawn is shown in Figure 1C.
[0122] In step S1104, the terminal determines the third brightness curve based on the first brightness curve and the second brightness curve.
[0123] In some embodiments, the third brightness curve is used to adjust the screen brightness of the terminal.
[0124] In some embodiments, the first portion of the first brightness curve is merged with the second portion of the second brightness curve to obtain a third brightness curve.
[0125] The first part refers to the portion of the first brightness curve that is located before the smallest parameter point among at least three first parameter points, and the second part refers to the portion of the second brightness curve that is located after the smallest parameter point among at least three first parameter points.
[0126] Optionally, the smallest parameter point includes the parameter point with the smallest x-coordinate value among at least three first parameter points. Alternatively, the smallest parameter point includes the parameter point with the smallest y-coordinate value among at least three first parameter points. Alternatively, the smallest parameter point includes the parameter point with the smallest x-coordinate and y-coordinate values among at least three first parameter points.
[0127] For example, referring to Figure 1D, by merging the curves of Figure 1B and Figure 1C in the manner described above, we can obtain the curve shown in Figure 1D.
[0128] In the method provided in this embodiment, the actual maximum brightness of the first brightness curve is clipped at points where it is too small. However, after determining the second brightness curve based on the first brightness curve, merging the first and second brightness curves to obtain the third brightness curve can display more high brightness while ensuring accurate brightness mapping.
[0129] The curve determination method involved in the embodiments of this disclosure may include at least one of steps S1101 to S1104. For example, step S1101 may be implemented as an independent embodiment, step S1102 may be implemented as an independent embodiment, step S1103 may be implemented as an independent embodiment, step S1104 may be implemented as an independent embodiment, steps S1101 and S1102 may be implemented as independent embodiments, steps S1101 and S1103 may be implemented as independent embodiments, steps S1101 and S1104 may be implemented as independent embodiments, steps S1102 and S1103 may be implemented as independent embodiments, steps S1102 and S1104 may be implemented as independent embodiments, and steps S1103 and S1104 may be implemented as independent embodiments, but are not limited thereto.

[0155] Figure 3 is a flowchart illustrating a curve determination method according to an embodiment of the present disclosure. As shown in Figure 3, the present disclosure relates to a curve determination method, which includes:
[0156] Step S3101: The current screen brightness of the terminal is Real-time Brightness, and the maximum brightness is Peak Luminance.
[0157] In step S3102, the terminal takes three feature points P0, P1, and P2 on the standard PQ curve.
[0158] Optionally, the coordinates of the three points P0, P1, and P2 are calculated as follows:
[0159] P1:[Real-time Brightness, Real-time Brightness]
[0160] P2:[x_p2,y_p2]
[0161] if Real-time Brightness<1000nits,
[0162] x_p2,y_p2=1000,Real-time Brightness
[0163] else:
[0164] x_p2, y_p2=Panel Peak Luminance, Real-time Brightness
[0165] P0:[x_p0,y_p0]
[0166] if Real-time Brightness>=1000nits,
[0167] x_p0,y_p0=Real-time Brightness,Real-time Brightness
[0168] else:
[0169] x_p0=y_p0=Real-time Brightness-Real-time Brightness*(1-Real-time Brightness / 1000)
[0170] Taking Real-time Brightness = 500 nits and Panel Peak Luminance = 1400 nits as an example,
[0171] The values of the three coordinates are P0[250,250], P1[500,500], and P2[1400,500].

[0173] In step S3104, the terminal merges the PQ curve and the Bezier quadratic curve to obtain the corresponding brightness mapping curve under Real-time Brightness.
