Any one of the color temperature adjusting devices provided in the embodiments of the present application may be integrated in an electronic device, where the electronic device may be a server or a terminal device, and the electronic device includes a smart phone, a Pad, a wearable device, a robot, a television, and other devices with a display function.
Referring to fig. 1, fig. 1 is a schematic flow chart of a color temperature adjustment method applied to an electronic device according to an embodiment of the present disclosure, the color temperature adjustment method includes the following steps.
And 101, displaying a hue disc on a display interface of the electronic equipment, wherein the hue disc is drawn based on the HSV color model.
The parameters of the colors in the HSV color model are respectively: hue (H), saturation (S), lightness (V).
The hue H is measured by an angle, and the value range is 0 ° to 360 °, which is calculated from red in the counterclockwise direction, red is 0 °, green is 120 °, blue is 240 °, and the complementary colors thereof are: yellow is 60 °, cyan is 180 °, and magenta is 300 °. The saturation S represents the degree of the color approaching the spectral color, wherein the larger the proportion of the spectral color is, the higher the degree of the color approaching the spectral color is, the higher the saturation of the color is, the higher the saturation is, the darker and brilliant the color is, the value range is usually 0-100%, and the larger the value is, the more saturated the color is. Lightness V represents the degree to which a color is bright, and typically ranges from 0% (black) to 100% (white).
The hue disk is a two-dimensional prototype-shaped hue disk and is used for displaying information such as hue, saturation, lightness and the like. The hue disk is drawn based on an HSV color model.
In an embodiment, before displaying the hue disk on the display interface of the electronic device, the color temperature adjustment method further includes: the hue disk is drawn based on the color model.
After the hue disk is drawn, the hue disk is displayed on a display interface of the electronic device. The hue disc is displayed as a whole in color on a display interface of the electronic equipment, and the center of the hue disc is displayed as white. As with the hue disk shown in fig. 2, it is noted that the hue disk in fig. 2 shows different gray levels, representing different colors.
And 102, responding to the clicking operation of the hue disc, and determining the clicking coordinates of the clicking operation.
The click operation may be a click operation for the hue disk input by an input device such as a mouse, such as a single click operation, a double click operation, a right click operation, or a touch operation for the hue disk. And are not particularly limited.
Specifically, by monitoring a click event (onTouchEvent) of the hue disc, when a click operation on the hue disc on the display interface is monitored, the click event of the hue disc is triggered, and a click coordinate of the click operation is determined and obtained through the click event.
Assuming that the center coordinate of the hue disc is O (a, b), the center coordinate is the first center coordinate or the second center coordinate; the radius of the hue disc is r, and the radius of the hue disc is the first radius of the first disc. The R point is a 0 degree point and belongs to a positive red color phase. P (x, y) is the point corresponding to the click operation, the angle corresponding to the counterclockwise rotation from the OR vector to the OP is angle, and the range of the angle value corresponding to angle is [0,360 ]. Wherein the hue disk is divided into four distinct quadrants.
The click coordinate P (x, y) of the click operation may be expressed as:
x＝a+Math.sin(angle*(Math.PI/180))*r
y＝b+Math.cos(angle*(Math.PI/180))*r
the coordinates of any point on the hue disk can be expressed according to the above formula.
103, determining a target HSV value according to the click coordinates.
Since the click operation is performed on the hue disc and the click event of the hue disc is monitored, the detected click coordinate of the click operation is located on the hue disc. A target color value, i.e., a target HSV value, may be determined based on the click coordinates.
The target HSV value comprises a target hue, a target saturation and a target brightness.
The click coordinates P (x, y) are obtained above. In one embodiment, whether the click coordinate is in the second disc is detected, and if yes, a value of a target tone corresponding to the click coordinate is set as a preset tone value; if not, determining the angle of the click coordinate on the hue disc, and determining the value of the target tone corresponding to the click coordinate according to the angle. For example, the preset tone value is 0.
Where the click coordinate is within the second disc, it can be expressed as Math.abs (x-a) < mInnerCicle & & Math.abs (y-b) < mInnerCicle. Where mlnnercycle represents the radius of the second disc. When the click coordinate is inside the second disk, the value hue =0 of the target hue is set.
If the click coordinate is not located in the second disk, assuming that lenA = math.abs (x-a) and lenB = math.abs (y-b), the angle of the click coordinate on the hue disk can be calculated from the coordinate values (located in the quadrant) of lenA, lenB, and P. This angle is determined as the value hue of the target hue, as shown in fig. 2.
In one embodiment, assuming that the radius r =1 of the hue disk, the length radius of the click coordinate from the center coordinate on the hue disk is determined, wherein radius ranges from [0,1.0]; the length radius is determined as the value of the target saturation, as shown in fig. 2.
In an embodiment, a value of the brightness of the target corresponding to the click coordinate is set as a preset brightness value. The preset brightness value may be a maximum value, such as 1.0.
In this way, based on the click operation of the user on the two-dimensional hue disk, the click coordinate of the click operation is converted into the target HSV value. Here, the hue value is set as an H signal value (value of target hue), the radius value is set as an S signal value (value of target saturation), and the V signal value (value of target lightness) is fixed to the maximum extremum of 1.0.
And 104, mapping the target HSV value into a color correction matrix.
Wherein, a Color Correction Matrix (CCM) is used to correct the Color display of the electronic device. And mapping the target HSV value into a color correction matrix so as to correct the color display of the electronic equipment according to the target HSV value for using the target HSV value corresponding to the clicking operation on the hue disc.
A step of mapping the target HSV value into a color correction matrix, comprising: mapping the target HSV value to an RGB signal value; a color correction matrix is constructed from the RGB signal values. The target HSV value is mapped into an RGB signal value through a conversion algorithm for converting HSV into RGB, the RGB signal value comprises three elements of R, G and B, and a 3 x 3 diagonal matrix is constructed by the three elements of R, G and B to obtain a color correction matrix.
And 105, adjusting the color input signals in the display pipeline according to the color correction matrix to realize color temperature adjustment of the electronic equipment.
Wherein a display pipe may also be understood as a rendering pipe in an electronic device.
In one embodiment, when the operating system of the electronic device is an android system, adjusting the color input signal in the display pipeline according to the color correction matrix includes: the color correction matrix is passed in through a rendering interface (interface of surface flicker) to adjust the color input signals in the display pipeline according to the color correction matrix. Specifically, the color correction matrix is multiplied by the color input signal to obtain a color output signal, and the color output signal is sent to the display screen. The color input signal may be an RGB input signal, and correspondingly, the color output signal is an RGB output signal.
The Surface Flinger is an independent rendering service in the android system, receives the surfaces corresponding to all windows as input, calculates the position of each Surface in a final composite image according to parameters such as ZOrder, transparency, size and position, then sends the position to hardware to generate a final display Buffer, and finally displays the final display Buffer on the electronic equipment. And adjusting the color input signals in the display pipeline according to the color correction matrix so as to realize color temperature adjustment of the electronic equipment.
It should be noted that in the android system, the interface of the surface flinger is native to the android system, and therefore, the interface can be used on all electronic devices of the android system.
In other embodiments, such as other operating systems, it is also necessary to input a color correction matrix into the display pipeline for adjusting the color input signals in the display pipeline to obtain the final adjustment of the color temperature of the electronic device.
In the embodiment of the method, the hue disc is displayed on the display interface, and the color temperature of the electronic equipment is adjusted based on the clicking operation of the hue disc, so that the color temperature adjusting mode is simple; and when the color temperature is adjusted, determining a target HSV value according to the clicking operation, mapping the target HSV value to obtain a color correction matrix, and finally adjusting the color input signals in the display pipeline according to the color correction matrix, so that the color input signals in the display pipeline of the electronic equipment can be adjusted according to the color correction matrix mapped by the clicking operation, and the purpose of finally adjusting the color temperature of each display interface displayed in the electronic equipment is achieved. The mode of colour temperature adjustment in the embodiment of this application is simple, swift, both can protect eyes, solves electronic equipment and to eyes stimulation and injury under no matter ambient light, can make the display effect more lively again, and the effectual of colour temperature adjustment is applicable to various electronic equipment, and realizes the colour temperature adjustment through click operation, presses close to user's use habit.
Please refer to fig. 3, fig. 3 is another schematic flow chart of the color temperature adjustment method according to the embodiment of the present disclosure. The color temperature adjusting method includes the following steps.
A hue disk is drawn based on the HSV color model 201.
In one embodiment, the step of drawing the hue disk based on the HSV color model includes: providing a first disk and a second disk, wherein a first radius of the first disk is greater than a second radius of the second disk; drawing a first disc by scanning gradation and radial gradation based on the HSV color model; drawing the second disk with white hue and different saturation degrees, so that the saturation degrees are sequentially reduced from a second center coordinate of the second disk to the edge; superimposing a second disk on the first disk such that a first center coordinate of the first disk is the same as a second center coordinate of the second disk; the first disk and the second disk after the superposition are used as hue disks.
Wherein the first radius of the first disk is greater than the second radius of the second disk, such that the first disk and the second disk visually appear as two circles of different radii. It should be noted that since hue in the HSV color model is measured in degrees, the first and second disks are provided for convenience in representing the corresponding HSV values.
When drawing the first disk, the lightness in the HSV color model may be set to 1 to reduce the calculation of lightness. The first disc drawn by scanning gradation and radial gradation based on the HSV color model is the disc corresponding to the circle with the largest cross-section in the HSV color model. The first disk appears to be a graduated color, but not white.
When the second disk is drawn, the second disk is drawn by using white hues and different saturations, wherein the saturation corresponding to the second center coordinate is the highest, that is, the center of the second disk presents the purest white color. From the second center coordinate to the edge, the saturation corresponding to the white color decreases in sequence.
After the first and second pucks are drawn, the second puck is superimposed on the first puck such that the first center coordinate of the first puck and the second center coordinate of the second puck coincide. And the first disc and the second disc after superposition are used as hue discs, namely the hue discs comprise a first disc (outer circle) and a second disc (inner circle) which have the same center coordinates and different radiuses, wherein the first disc and the second disc are drawn by adopting different methods.
The hue disk obtained after superposition is two-dimensional, the closer the hue disk is to the center, the white is displayed, and the farther the hue disk is to the edge, the gradually changed color is displayed.
The obtained hue disc accords with the use habit of a user, so that the use experience of the user on the hue disc is improved.
202, displaying the hue disk on a display interface of the electronic device.
And 203, responding to the clicking operation of the hue disc, and determining clicking coordinates of the clicking operation.
And 204, determining a target HSV value according to the click coordinate.
Please refer to the above description of the corresponding steps in steps 202 to 204, which is not repeated herein.
The scheme corresponding to the embodiment of the application needs to be used on a plurality of electronic devices of different models, the electronic devices of different models correspond to different display screen modules, the optical characteristics of the display screen modules are different, and meanwhile, the scheme corresponding to the embodiment of the application can be correspondingly applied in different color modes even if the scheme is used on the same electronic device, and the image quality adjustment of the color models is different; therefore, the same click coordinate in the hue disc appears, and the color temperature and the change degree of the color temperature have great difference on different electronic devices or different color modes. To solve this problem, steps 205 to 206 are also included before the step of mapping the target HSV value into the color correction matrix.
205, a white point displacement correction variable is obtained, where the white point displacement correction variable includes correction amounts corresponding to a preset number of hues.
In the embodiment of the application, a white point displacement correcting variable dUVtuning is introduced, and the white point displacement correcting variable is used for correcting the white point of a screen, so that the variation trend of hue and saturation corresponds to the click coordinates of a user on a hue disc qualitatively. In the embodiment of the present application, this is achieved by correcting the S signal value (radius value) in the target HSV value. For example, when the color temperature adjustment method in the present application is debugged in a given color mode in a certain model of electronic equipment, if the radius value of a certain hue (hue) is changed and the obtained white point displacement (degree of color change) is too large or too small, the change trend of the white point displacement can be corrected by modifying the correction value corresponding to the hue (hue) in the white point displacement correction variable and modifying the corresponding S signal value according to the correction value.
The white point position correction variable is obtained by testing and adjusting the electronic equipment to which the color temperature adjusting method in the embodiment of the application is applied by corresponding testing personnel before the electronic equipment leaves a factory.
The white point displacement correction variable includes correction amounts corresponding to a predetermined number of hues, and the correction amounts may also be referred to as correction amount parameters. Wherein the preset number may be 3, 6, 12, etc. The more the preset number is, the finer the adjustment is, the better the adjustment effect is, but the harder the test before delivery. In the embodiments of the present application, the preset number is 6 as an example for description.
The 6 hues correspond to the 6 primary hues on the hue disc, i.e., red, yellow, green, cyan, blue, violet, respectively. The correction amounts corresponding to the 6 hues are correction amounts corresponding to red, yellow, green, cyan, blue, and violet, respectively.
And 206, modifying the target HSV value according to the correction quantity to obtain the modified target HSV value.
In one embodiment, step 206 includes: calculating a target correction corresponding to a target tone in the target HSV value by using a linear interpolation algorithm according to the correction; modifying a value of a target saturation in the target HSV value according to the target correction; and taking the target HSV value with the modified target saturation value as the modified target HSV value.
Since the white point displacement correction variable includes the correction amounts corresponding to the 6 hues, and the value of the target hue in the target HSV value is not necessarily exactly any one of the 6 hues, the target correction amount corresponding to the target hue value in the target HSV value is calculated by using a linear interpolation algorithm. It is understood that the correction amount of any hue angle between 6 hues can be obtained by a linear interpolation algorithm.
And after the target correction quantity is obtained by utilizing a linear interpolation algorithm, modifying the value of the target saturation in the target HSV value according to the target correction quantity. In an embodiment, the S signal value may be modified by the formula S = target correction amount × radius, i.e. the value of the target saturation is modified by the formula. It should be noted that after the target HSV value is obtained, the S signal value in HSV is corrected according to the target correction amount, that is, the value of the target saturation is corrected. And taking the target HSV value with the modified target saturation value as the modified target HSV value.
When the target correction amount is smaller than the target saturation value, at the same point on the hue disk, (i.e. the same click coordinate), after correction, the point changes to the direction in which the color is not saturated, i.e. the color becomes lighter, because the corresponding target saturation value becomes smaller. When the target correction amount makes the value of the target saturation larger, at the same point (i.e. the same click coordinate) on the hue disk, after correction, the point changes to the direction in which the color is more saturated, i.e. the color becomes darker, because the value of the corresponding target saturation becomes larger.
And 207, mapping the modified target HSV value into a color correction matrix.
And 208, adjusting the color input signals in the display pipeline according to the color correction matrix so as to realize color temperature adjustment of the electronic equipment.
Please refer to the above description of the corresponding steps in step 207 to step 208, which is not described herein again.
According to the embodiment, a white point displacement modification variable is introduced, the target HSV value is modified according to the correction quantity in the white point displacement modification variable, the color correction matrix is mapped according to the modified target HSV value, and the target HSV value corresponding to the click operation is changed through the white point displacement modification variable, so that the white point displacement modification variable can be better used on any electronic equipment, and the user requirements can be met in a wider range.
In an embodiment, the color temperature adjusting method further includes: and when the mode of the electronic equipment is detected to be a preset mode, setting the function of the hue disc displayed on the display interface to be in an unavailable state. Wherein, the function of the preset mode and the function of the hue disc have mutual exclusion. For example, the preset mode may be an eye-protection mode, a reading mode, a power saving mode, and the like.
In one embodiment, setting the function of the hue disk displayed on the display interface to be in an unavailable state comprises: and setting the hue disc displayed on the display interface as non-clickable and setting the display color of the hue disc to be displayed as gray and other colors. Thus, the user is reminded that the current hue disk function is unavailable.
According to the method described in the above embodiments, the present embodiment will be further described from the perspective of a color temperature adjustment device, which may be specifically implemented as a separate entity or integrated in an electronic device.
