Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
a method for realizing brightness and color temperature two-dimensional control based on a touch screen comprises the following steps:
s1, click on the touch screen to enter a brightness and color temperature setting interface, as shown in fig. 1, the brightness and color temperature setting interface includes three regions, which are defined as a first region, a second region, and a third region from the outside to the inside.
Wherein, the first area, the second area and the third area are further distinguished according to the following rules:
the first region is a boundary region of a brightness and color temperature setting interface, and the boundary region is a region which is not easy to click by fingers;
the second area is a main area of a brightness and color temperature setting interface, and the main area is a normal selection area which is easily selected by fingers;
and the third area is a color development area of the brightness and color temperature setting interface, and the color development area is a combined color for synchronously displaying the brightness and the color temperature of the selected point.
And S2, randomly touching and selecting one point on the touch screen, and acquiring the position of the selected point in the three areas of the brightness and color temperature setting interface.
S3, performing boundary analysis on the selected point, and obtaining the resolution coordinates (X, Y) of the selected point as shown in fig. 2.
Further, if the selected point is in the second or third area of the interface for setting brightness and color temperature, the resolution coordinate of the selected point is executed, and if the selected point is in the first area of the interface for setting brightness and color temperature, the point is considered to be beyond the main area, that is, the point reaches the boundary area, the boundary coordinate of the selected point is executed, and the boundary coordinate is the resolution coordinate of the boundary point in the corresponding main area.
And S4, obtaining the brightness value and the color temperature value of the point according to the corresponding relation between the resolution coordinate and the brightness and the color temperature, as shown in FIG. 3.
When the brightness value and the color temperature value of the point are obtained according to the corresponding relation between the resolution coordinate and the brightness and the color temperature, the specific corresponding relation is as follows:
when the screen resolution is 480 × 480, the brightness value of 0% -100% corresponds to the resolution of 0-480 of the X axis, and the color temperature value of 2700K-6500K corresponds to the resolution of 0-480 of the Y axis;
luminance X/480X 100%;
color temperature Y/480 x (6500-.
When the screen resolution is 720 × 720, the brightness value of 0% -100% corresponds to the resolution of 0-720 of the X axis, and the color temperature value of 2700K-6500K corresponds to the resolution of 0-720 of the Y axis;
luminance X/720X 100%;
color temperature Y/720 x (6500-.
And S5, displaying the color effect of the combination of the brightness and the color temperature in the third area of the brightness and color temperature setting interface according to the corresponding relation of the brightness and the transparency and the corresponding relation of the color temperature and the RGB color.
The method for carrying out the correspondence between the brightness and the transparency is that the brightness display adopts the opacity of 32-bit color, and the opacity is 10-255 corresponding to the brightness of 0-100%.
The method for carrying out the relationship correspondence between the color temperature and the RGB color is to carry out high-precision conversion by adopting a chart fitting algorithm, wherein the chart fitting algorithm is designed based on a Charit's original black body values reverse engineering mode, and a piecewise fitting formula from the color temperature to the RGB color is obtained.
S6, the brightness value and the color temperature value are issued to the sub-equipment, the brightness and the color temperature of the sub-equipment can be controlled, the PLC controller issues instructions to the sub-equipment about the parameters of the brightness value and the color temperature value, and the sub-equipment can be a lamp.
Example two:
based on the method for implementing two-dimensional control of brightness and color temperature based on touch screen as described in the first embodiment, when the corresponding relationship between color temperature and RGB color is studied, a reliable formula is implemented in a Charity's original black body values reverse engineering manner, as shown in fig. 8, it can be found that, in a data chart based on the Charity's original black body values reverse engineering manner, the red component always maintains 255 when the red component is below 6600K, the blue component always maintains 0 when the blue component is 2000K, and the blue component always maintains 255 when the blue component is above 6500K. To better fit these data, the green component is divided into two parts for fitting. Some are below 6600K; the other part is above 6600K, after which the data is split into separate color components for fitting, but excluding those always 0 and 255. For the data of the X axis and the Y axis, the numerical value difference is too large, the numerical value of the X axis is larger than 1000, and for the Y axis, the numerical value range is between 0 and 255, so that the data of the X axis needs to be correspondingly converted to better perform curve fitting. For the purpose of best fit, the data of the X-axis is divided by 100 and shifted accordingly, as shown in fig. 4-7, which are the data distribution of each component and the best fit curve, respectively, and it can be seen that the curve fit is good. Thus, a piecewise fitting formula from color temperature to RGB color is obtained. According to the formulas, the conversion between the color temperature and the RGB color can be realized, the simplification of user operation is realized, and the user can intuitively feel the actual brightness and color temperature effect of the selected screen point.
The invention has the beneficial effects that:
according to the method for realizing the two-dimensional control of the brightness and the color temperature based on the touch screen, the brightness and the color temperature can be simultaneously set in one step by adopting a two-dimensional plane mode on a setting interface, the problem that edge points are not easy to select is solved, meanwhile, the combined color of the brightness and the color temperature of the point selected by a user can be synchronously displayed in the third area of the screen, the method is visual and clear, the user operation is simplified, and the user can visually feel the actual brightness and color temperature effects of the selected screen point.
