In recent years, with the rapid development and the increasing updating of the related technologies of smart homes, products related to smart lighting are continuously updated. To meet the increasing demand of people, intelligent lighting products often need to support the gradual change function.
In intelligent lighting, gradual change refers to a slow transition process when the state of an intelligent bulb changes, such as brightness changes from bright to dark or from dark to bright, color temperature changes from cold to warm or from warm to cold, and color changes from one color to another.
However, the gradual change display effect of the current intelligent lighting product is poor, and the gradual change state of the intelligent bulb is often abrupt and monotonous, for example, the brightness of the intelligent bulb changes with a slight shake or a "flash lamp" effect, so that the visual burden of people is increased, and the user experience is not good.
In order to solve the above problems, the present invention provides a gradual change effect control method for an intelligent bulb.
Referring to fig. 1, in an embodiment of the present invention, the present invention provides a gradual effect control method for an intelligent light bulb, including the following steps:
step S101, acquiring a preset initial state value, a preset target state value and the number of issued state instructions in unit time;
the preset initial state value, the preset target state value and the number of issued state instructions in unit time can be set according to user requirements, and the number is not specifically limited;
as known to those skilled in the art, for a frame, if the frame is greater than or equal to 24 frames in 1 second, the frame is seen to be continuous by naked eyes, and if the frame is less than 24 frames in 1 second, a ghost phenomenon occurs, in order to prevent the ghost phenomenon from bringing bad visual experience to a user, in this embodiment, the number of issued status instructions in unit time is greater than 24, and the number of issued status instructions in unit time is a positive integer; the unit time may be 1 second or other, and is specifically set according to user requirements, which is not specifically limited herein;
fig. 2 is a coordinate diagram for describing the operation principle of the linear interpolation algorithm according to an embodiment of the present application, and for facilitating understanding of the operation principle of the linear interpolation algorithm, the operation principle of the linear interpolation algorithm is now described as follows, please refer to fig. 2, assuming that (x0, y0) and (x1, y1) are respectively an abscissa value and an ordinate value known in the coordinate system, and if interpolation is performed at x, a value of y is calculated, wherein the calculation formula of y is as follows:
step S102, calculating the state value and the issuing time of each state instruction through a linear interpolation algorithm, and issuing the corresponding state value at each issuing time; as can be seen from fig. 2, under the condition that the preset initial state value, the preset target state value and the number of issued state instructions in unit time are known to be obtained, the state value and the issuing time of each state instruction can be obtained through a linear interpolation algorithm, and then, the corresponding state value is issued at each issuing time; it is easy to understand that when the unit time changes, the issue time also changes, and the time interval of each issue is obtained by dividing the unit time by the number of issued status commands in the unit time, and under the condition that the initial issue time is known, the time interval of each issue can be calculated according to the initial issue time and the time interval of each issue, for example, if the number of issued status commands in the unit time (if the unit time is 1 second) is 100, the status value of each status command is issued every 10 milliseconds, and under the condition that the initial issue time is 8 points, the issue times are sequentially (8 points 0 minutes 0 seconds 10 milliseconds), (8 points 0 minutes 0 seconds 20 milliseconds), (8 points 0 minutes 0 seconds 30 milliseconds) … … (8 points 0 minutes 1 second 0 milliseconds);
it is easy to understand that, in the present embodiment, in the process of changing the intelligent bulb from the initial state value to the target state value, the corresponding state value is issued at each issuing time, so that a smooth change from one state to another state is realized.
Step S103, the state value is mapped into a driving current value, and the intelligent bulb is driven to display an effect, so that the intelligent bulb has a slow transition process in the gradual change process, and the situations of sudden and monotonous gradual change states can not occur, so that the gradual change effect is good, the visual focus, the atmosphere and the aesthetic feeling of a user can be attracted to be improved, the user experience is greatly improved, and the problem of poor gradual change effects of sudden and monotonous states of the intelligent bulb in the related technology is solved.
In the technical scheme of this embodiment, first, a preset initial state value, a preset target state value and the number of issued state instructions in unit time are obtained; then, calculating the state value and issuing time of each state instruction through a linear interpolation algorithm, and issuing corresponding state values at each issuing time; and finally, mapping the state value into a driving current value, and driving the intelligent bulb to display the effect, so that the smooth change from one state to another state is realized in the process that the product changes from the initial state value to the target state value, the gradual change effect is good, the method not only can attract the visual focus of a user, improve the atmosphere and the aesthetic feeling, but also greatly improves the user experience, and solves the problem of poor gradual change effect of the intelligent bulb, such as abrupt and monotonous state in the related technology.
To achieve a better fade effect, please refer to fig. 3, wherein in some embodiments, the status value comprises at least one of a color status value, a color temperature status value and a brightness status value.
Specifically, in an embodiment, in the case that the state value is a color state value, calculating the state value of each state command through a linear interpolation algorithm includes the following steps:
step S301, calculating a color gradient value according to a preset initial state value, a preset target state value and the number of issued state instructions in unit time, wherein the calculation formula of the color gradient value is as follows:
wherein, X0 is a preset initial state value, Xn is a preset target state value, N is the number of issued state commands in a preset unit time, and Δ X is a color gradient value;
step S302, calculating a state value of each color state command according to the color gradient value and a preset initial state value, wherein a calculation formula of the state value of each color state command is as follows:
Xi＝X0+ΔX×i
wherein, X0 is a preset initial state value, Δ X is a color gradient value, i is the number of times of issuing color state commands, and Xi is the state value of the ith color state command.
Fig. 4 is a schematic diagram of a gradual change process of the intelligent light bulb from the color state a to the color state B according to an embodiment of the present application, as shown in fig. 4, in order to describe the state of the intelligent light bulb by taking color as an example, a data structure is defined herein, which has the following pseudo code:
typedef struct smart_light_status{
unsigned char red；
unsigned char green；
unsigned char blue；
}smart_light_status；
in the above code, R represents red (red), G represents green (green), and B represents blue (blue), and red, green, and blue have values ranging from 0 to 255, and thus represent the color state RGB (red, green, blue) of the smart bulb.
Therefore, assuming that the intelligent light bulb changes from state a to state B, the corresponding preset initial state values and target state values have the following pseudo-codes:
A.red--->B.red
A.green--->B.green
A.blue--->B.blue
the red color image is obtained by performing color matching on a red color image, a green color image and a blue color image, wherein A.red is a preset red initial state value, A.green is a preset green initial state value, A.blue is a preset blue initial state value, B.red is a preset red target state value, B.green is a preset green target state value, and B.blue is a preset blue target state value;
considering that red light, green light and blue light with different proportions can be mixed into countless different colors of light, in order to increase richness of light color change and improve user experience, in the embodiment, the color state values at least include a red state value, a green state value and a blue state value. The red state value, the green state value, and the blue state value can be obtained through the calculation formulas in steps S301 to S302, and therefore, the details are not repeated here.
And after the red state value, the green state value and the blue state value are obtained, issuing the corresponding red state value, green state value and blue state value at each issuing time. For example, referring to fig. 4, the preset initial color state value is (a.red, a.green, a.blue), that is, (R0, G0, B0), the time at this time is T1, the preset target color state value is (b.red, b.green, b.blue), that is, (Rn, Gn, Bn), the preset time of issuing is Tn, the color state value is issued when the time reaches T1 (R1, G1, B1), the color state value is issued when the time reaches T2 (R2, G2, B2), the color state is issued when the time reaches T3 (R3, G3, B3), … …, until the color state changes from the preset initial color state value to the target color state value, so that the process is rich in color change, and meanwhile, the intelligent light bulb color has a slow transition process, and therefore, the effect is good.
In an alternative embodiment, the number of issued status commands per unit time (within 1 second) is 64. Through a plurality of tests, the skilled person in the art finds that the color gradient effect of the intelligent bulb is more vivid and mild when the number of the issued status commands in the preset unit time is 64. Of course, in some other embodiments, the number of status commands issued in a preset unit time may also be set to be other, and is not specifically limited herein.
In some embodiments, in the case that the state value is a brightness state value, calculating the state value of each state command through a linear interpolation algorithm includes the following steps:
calculating a brightness gradient value according to a preset initial state value, a preset target state value and the number of issued state instructions in unit time;
and calculating the state value of each brightness state instruction according to the brightness gradient value and a preset initial state value.
The brightness of the intelligent bulb can be changed from bright to dark or from dark to bright through the steps, so that smooth gradual change of the brightness is realized, and the gradual change effect is good; in addition, since the calculation formulas of the brightness gradient value and the state value of the brightness state command are similar to those in steps S301 to S302, the detailed description thereof is omitted here.
In some embodiments, in the case that the state value is a color temperature state value, calculating the state value of each state command by using a linear interpolation algorithm includes the following steps:
calculating a color temperature gradient value according to a preset initial state value, a preset target state value and the number of issued state instructions in unit time;
and calculating the state value of each color temperature state instruction according to the color temperature gradual change value and a preset initial state value.
The color temperature of the intelligent bulb can be changed from cold to warm or from warm to cold through the steps, so that the smooth gradual change of the color temperature is realized, and the gradual change effect is good; in addition, since the calculation formulas of the color temperature gradient value and the state value of the color temperature state instruction are similar to those in steps S301 to S302, the detailed description thereof is omitted here.
