Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a method for adjusting display parameters, as shown in fig. 1, the method mainly comprises the following steps:
101. and acquiring actual display parameters and target display parameters of the display device.
Wherein the actual display parameters comprise first parameter values and the target display parameters comprise second parameter values.
In the field of display technology, the displayed effect is based on different display standards, and the parameters corresponding to the display effect are different, wherein the display standards can be understood as standards for defining the displayed color and image as numerical values according to certain rules. Such as the CIE1931 standard. In the study of color perception, the CIE1931 XYZ color space (also called CIE1931 color space) is one of the first mathematically defined color spaces, which was created by the international commission on illumination (CIE) in 1931. The CIE XYZ color space was derived from a series of experiments conducted by two experts in the late 1920 s, the results of which were incorporated into the specification for the CIE RGB color space, from which the CIE XYZ color space was derived.
In the process of RGB representation of display colors, the intensity values are between 1 and 255, here for convenience of display in the CIE1931 color space, the intensities of the three color channels are normalized, as shown in fig. 1-a, in the RGB triangle under the CIE1931 standard, the display result formed by the three color channels is in the range of 0 to 1, here, when RGB (three color channels) increases the component of a certain channel, the whole triangle is moved from the center direction to the vertex direction. Thus, as can be seen in FIG. 1-A, red becomes purer and purer along the positive x-axis, green becomes purer along the positive y-axis, and the purest blue is located near the origin of coordinates. Therefore, when the display displays pure red, the value of x (horizontal axis) in the actual display value is maximum; similarly, when displaying green, the y value in the actual displayed value is the largest, so it can be seen that R and B mainly affect the abscissa, G mainly affects the ordinate, and the adjustment directions of R and B are exactly opposite, but the adjustment magnitudes are not very same. Therefore, when the actual display effect is more bluish than the target display effect, it is most effective to reduce the input amount of the B channel, and on the contrary, when the actual display effect is weaker than the target effect in blue, it is more effective to increase the input amount of the B channel, that is, in the process of calibrating the parameters of the monitoring apparatus, the actual display effect will be directly influenced by the input amount of the different color channels of RGB, and the influence strength under different effects is different.
Based on this, in order to ensure the correction of the subsequent step, in this step, the effect currently displayed and the display effect desired to be achieved (i.e. the target display effect described in the embodiment of the present invention) may be obtained as the basis for comparing the expected effect subsequently. Meanwhile, based on the foregoing, the display effect is actually represented by a numerical value under the CIE1931 standard, and therefore, in the embodiment of the present invention, the actual display parameter includes a first parameter value for representing the display effect, and the target display parameter includes a second parameter value for representing the display effect.
102. And determining the input parameters to be adjusted and the adjustment amplitude according to the relationship between the first parameter value and the second parameter value and the preset adjustment amplitude relationship.
The preset adjustment amplitude is provided with different difference value intervals and corresponding adjustment amplitudes.
The expected display effect is different from the actual display effect, that is, the actual display parameter is different from the target display parameter in the implementation of the present invention. The desired display effect may be understood as a display effect that the user wants to achieve. As can be seen from the foregoing description in step 101, the influence of different color channels on the actual display parameters is different, and therefore, in the embodiment of the present invention, it is necessary to first determine the relationship between the actual display parameters and the target display parameters, where the relationship between the actual display parameters and the target display parameters may have the following four cases: here, when in the CIE1931 standard, the actual display parameters and the target display parameters may be represented numerically based on the horizontal and vertical axes, that is, the actual display parameters (real x, real y) and the target display parameters (rational x, rational y). x is considered separately from y, and these four cases can be shown in table 1 below:
TABLE 1
The input channel of the adjustment can be performed according to the above four relationships, that is, when x is greater than rational x and y is greater than rational y, the relationship between the actual display parameter and the target display parameter is as in case 1, which indicates that the input value of the B channel needs to be adjusted, and the actual display effect can be changed by modifying the input value of the B channel, so that the modified actual display parameter approaches to the target display parameter.
When the channel of the input parameter to be adjusted is determined, and the input parameter is determined to be increased or decreased, the adjustment amplitude of the input quantity to be adjusted needs to be further confirmed. In the embodiments of the present invention, the following modes are included but not limited to: since the adjustment range will directly affect the change of the adjusted actual display parameter, when the actual display parameter and the target display parameter are determined, the adjustment range can also be determined according to the difference between the actual display parameter and the target display parameter. In this way, the adjustment magnitude that needs to be adjusted subsequently may be determined based on the difference between the actual display parameter and the target display parameter. For example, when the actual display parameters (real x is 0.45; real y is 0.45) and the target display parameters (real x is 0.42; real y is 0.42) at this time, it may be determined that the difference between the actual display parameters (real x-real x is 0.2; real y-real y is 0.03) is greater than 0.02, and it is determined that the corresponding adjustment width when the difference is greater than 0.02 is 0.2 based on the preset adjustment width relationship, the adjustment width of the input amount of the channel that needs to be adjusted may be set to 0.2. Of course, the relationship between the adjustment range and the difference value in the embodiment of the present invention may be selected according to actual conditions according to user requirements, or the relationship between the adjustment range and the difference value may be determined based on results obtained after multiple tests, so as to set the adjustment range corresponding to each difference value range, which may be set according to actual requirements without limitation.
103. And modifying the input parameters of the display device according to the input parameters to be adjusted and the adjustment amplitude so as to ensure that the updated actual display parameters corresponding to the modified input parameters approach the target display parameters.
Wherein, when the input parameter and the adjustment amplitude to be adjusted are determined, the input and the change of the input size of the color channel to be adjusted are actually determined. Because the deviation generated by the display during displaying includes a plurality of factors, and the interference factor is not a simple linear influence, (which may be that the display effect is more red, more green, more blue, or a combination of any of the three), in the adjusting process, the input parameter needs to be modified by adjusting the amplitude according to the method described in this step, so that the display result is closer to the target display effect (i.e., the actual display parameter is closer to the target display parameter). Meanwhile, the method of the present invention can execute the loop for any number of times again after executing the one-time correction of 101-103, and continuously perform the correction, so that the result after the multiple corrections is closer to the display result that the user wants to obtain (i.e. the actual display parameters obtained after the multiple loop operations and updated for N times are closer to the target display parameters). Therefore, the new input quantity can be obtained by adjusting on the basis of the original input quantity in the color channel, and the updated actual display parameter corresponding to the modified input parameter is obtained by inputting the new input quantity.
Compared with the method for adjusting display parameters by manually operating software at present, the method for adjusting display parameters provided by the embodiment of the invention can determine input parameters and adjustment amplitudes to be adjusted by acquiring actual display parameters and target display parameters of a display device, wherein the actual display parameters comprise first parameter values, the target display parameters comprise second parameter values, then according to the relationship between the first parameter values and the second parameter values and the relationship between preset adjustment amplitudes, the preset adjustment amplitudes are provided with different difference intervals and corresponding adjustment amplitudes, and then according to the input parameters and the adjustment amplitudes to be adjusted, the input parameters of the display device are modified to ensure that the updated actual display parameters corresponding to the modified input parameters approach the target display parameters, so that the actual display parameters and the target display parameters of the monitor can be compared and the output parameters of the monitor can be automatically adjusted based on the comparison between the actual display parameters and the target display parameters of the monitor And parameters are input, so that the function that a user needs to use software to correct the display effect of the parameters of the monitor by himself is avoided, and the labor consumption is reduced.
Further, according to the method shown in fig. 1, another embodiment of the present invention provides another method for adjusting display parameters, as shown in fig. 2, the method mainly includes:
201. and acquiring actual display parameters and target display parameters of the display device.
Wherein the actual display parameters comprise first parameter values and the target display parameters comprise second parameter values.
In this step, the actual display parameters of the monitor may be obtained in any manner, for example, the monitor program of the monitor may obtain the actual display results of a current certain pixel point and obtain the actual display parameters after normalization.
Then, according to the relationship between the first parameter value and the second parameter value and a preset adjustment amplitude relationship, determining an input parameter to be adjusted and an adjustment amplitude, wherein the specific process can be performed according to the following steps 202 to 207.
The input parameters comprise R channel parameters, G channel parameters and B channel parameters.
Specifically, the step may include:
202. and determining a first parameter value of the actual display parameter and a second parameter value of the target display parameter according to a preset image display standard.
The first parameter value and the second parameter value both comprise a horizontal axis value and a vertical axis value. The preset image display standard in the embodiment of the invention is the CIE1931 standard. Thus, the first parameter value is (real x, real y) and the second parameter value is (rational x, rational y). The values of x and y range from 0 to 1.
203. And comparing the horizontal axis value with the vertical axis value of the first parameter value with the second parameter value respectively to obtain a comparison result.
The results of the comparison included four cases, as shown in table 2 below.
TABLE 2
204. And setting the parameter adjustment relation.
The parameter adjustment relationship includes a first adjustment relationship, a second adjustment relationship, a third adjustment relationship and a fourth adjustment relationship.
Since the comparison result includes 4 cases, four corresponding relationships are also included when setting the parameter adjustment relationship:
1) the first adjustment relation is that if the horizontal axis value and the vertical axis value of the first parameter value are respectively smaller than the horizontal axis value and the vertical axis value of the second parameter value, the input value of the B channel parameter is reduced;
2) if the horizontal axis value of the first parameter value is smaller than the horizontal axis value of the second parameter value and the vertical axis value of the first parameter value is larger than the vertical axis value of the second parameter value, reducing the input value of the G channel parameter or increasing the input value of the R channel parameter;
3) if the horizontal axis value of the first parameter value is greater than the horizontal axis value of the second parameter value and the vertical axis value of the first parameter value is less than the vertical axis value of the second parameter value, reducing the input value of the R channel parameter or increasing the input value of the G channel parameter;
4) the fourth adjustment relationship is to increase the input value of the B-channel parameter if the horizontal axis value and the vertical axis value of the first parameter value are greater than the horizontal axis value and the vertical axis value of the second parameter value, respectively.
The specific four parameter adjustment relationships can be shown in table 3:
TABLE 3
205. And determining the input parameters to be adjusted according to the comparison result and the parameter adjustment relation.
The parameter adjusting relationship comprises each comparison result and the corresponding input parameter to be adjusted. Determining an adjustment parameter relation according with the comparison result from the first adjustment parameter relation, the second adjustment parameter relation, the third adjustment parameter relation and the fourth adjustment parameter relation, and determining the input parameter to be adjusted according to the adjustment parameter relation of the comparison result.
206. And setting a preset adjustment amplitude relation.
The preset adjustment amplitude relationship comprises each difference interval and the corresponding adjustment amplitude.
Specifically, according to an actual test, each difference interval in the preset adjustment range and the corresponding adjustment range may be set as follows: when the difference is greater than 0.02, the adjustment amplitude is 0.2; when the difference is between 0.02 and 0.015, the modulation amplitude is 0.1; when the difference is between 0.015 and 0.012, the modulation amplitude is 0.05; when the difference is less than 0.012, the adjustment amplitude is 0.02. Wherein the difference is a larger value minus a smaller value between the lateral axis values of the first parameter value and the second parameter value and a larger value minus a smaller value between the longitudinal axis values.
207. And calculating the difference value between the horizontal axis value and the vertical axis value in the first parameter value and the second parameter value, determining a target difference value, and determining an adjustment amplitude according to the target difference value and a preset adjustment amplitude relation.
The preset adjustment amplitude relationship comprises different difference intervals and corresponding adjustment amplitudes.
Further, in the process of determining the adjustment amplitude, specifically, the following may be performed:
performing difference operation on the horizontal axis value and the vertical axis value in the first parameter value and the second parameter value respectively to obtain a first difference value and a second difference value, wherein the first difference value is the difference value of the horizontal axis value of the first parameter value and the second parameter value, and the second difference value is the difference value of the vertical axis value of the first parameter value and the second parameter value;
and determining the smaller one of the first difference value and the second difference value as the target difference value, and determining the adjustment amplitude corresponding to the difference value interval to which the target difference value belongs according to the target difference value and the preset adjustment amplitude relation.
For example, as shown in fig. 2-a, assuming that a first parameter value (real x is 0.45; real y is 0.37) and a second parameter value (rational x is 0.49; rational y is 0.383), it can be determined that when a first difference (rational x-real x is 0.49-0.45-0.04) and a second difference (rational y-real y is 0.40-0.37-0.0013), the comparison result between the first parameter value and the second parameter value is real x < rational x; real y < physical y can determine the corresponding first adjustment relationship, namely the input quantity of the B channel needs to be reduced;
meanwhile, the preset adjustment amplitude is as follows: when the difference is greater than 0.02, the adjustment amplitude is 0.2; when the difference is between 0.02 and 0.015, the modulation amplitude is 0.1; when the difference is between 0.015 and 0.012, the modulation amplitude is 0.05; when the difference is less than 0.012, the adjustment amplitude is 0.02. Thus, based on the first difference (0.04), the second difference (0.013), and thus in fact the smaller of the two, the second difference (0.013), can be determined, the second difference can be determined to be chosen as the target difference, and 0.013 is between 0.015 and 0.012, which then determines 0.05 when the magnitude of the desired adjustment is in accordance with the predetermined adjustment magnitude relationship. Therefore, it can be determined that the B channel needs to be reduced and the adjustment range is 0.05.
208. And modifying the input parameters of the display device according to the input parameters to be adjusted and the adjustment amplitude so as to ensure that the updated actual display parameters corresponding to the modified input parameters approach the target display parameters.
After the adjustment range is determined in the foregoing steps, it is further necessary to determine a new input parameter actually required based on the adjustment range, that is, the modified input parameter described in the embodiment of the present invention.
Specifically, the method comprises the following steps:
determining the adjusted input parameters through a preset formula according to the input parameters to be adjusted and the adjustment amplitude;
wherein the preset formula comprises:
wherein R is an R channel input parameter, G is a G channel input parameter, B is a B channel input parameter, R ' is an adjusted R channel input parameter, G ' is an adjusted G channel input parameter, and B ' is an adjusted B channel input parameter; p1 to P9 are adjustment coefficients, respectively.
The parameter matrix of P1-P9 is introduced in the embodiment of the invention, and the principle based on the matrix can be known as follows:
R’＝P1*R+P2*G+P3*B；
G’＝P4*R+P5*G+P6*B
B’＝P7*R+P8*G+P9*B
from the above formulas, it is found that P1, P2 and P3 affect the results of R, P4, P5 and P6 affect the results of G, and P7, P8 and P9 affect the results of B. When a component R, G, B is 0, if R ≠ 0, G ≠ 0, and B ≠ 0, the result is not affected regardless of the changes of P1, P4, and P7, and the significant coefficients are only P2, P3, P5, P6, P8, and P9. Therefore, there are 4 cases:
1, R, G, B is not 0, then P1-P9 are all effective coefficients;
2, R, G, B, if 1 is 0, then there are 6 significant coefficients in P1-P9;
3, R, G, B, 2 of which are 0, then 3 effective coefficients are in P1-P9;
and 3 of the 4 and R, G, B are 0, the P1-P9 have 0 effective coefficients.
Thus, based on the above analysis, when the input parameter is adjusted based on the adjustment width, it is also possible to first determine the effective coefficients, which are some of the 9 adjustment coefficients that are effective. Further, according to the input parameter to be adjusted and the adjustment amplitude, the adjusted input parameter is determined by a preset formula, which may specifically be performed in the following manner:
firstly, determining an effective coefficient in the adjustment coefficients according to specific input values of the R-channel input parameter, the G-channel input parameter, and the B-channel input parameter, where the effective coefficient is an adjustment coefficient corresponding to a case where the specific input values of the R-channel input parameter, the G-channel input parameter, and the B-channel input parameter are not 0.
Then, determining a specific value of an adjustment coefficient corresponding to the input parameter to be adjusted according to the input parameter to be adjusted and the adjustment amplitude;
and finally, determining the adjusted input parameters corresponding to the input parameters to be adjusted according to the specific values of the adjustment coefficients.
For example, when it is determined that the most primitive parameter matrix is an identity matrix, i.e., R ', G ', B '.
When the G component is supposed to be increased, P4 is 0, P5 is 1, and P6 is 0 in the unit matrix, it is only necessary to increase P4 and P6, and when the G component is supposed to be decreased, P4 is 0, P5 is 1, and P6 is 0 in the unit matrix, it is only necessary to decrease P5.
In addition, if P5<1 before a certain adjustment, P5 is preferably added to 1 to ensure that the transition matrix approaches the identity matrix as much as possible. If P4>0 or P6>0 is adjusted before a certain time, P4 and P6 are preferably reduced to 0 to ensure that the transformation matrix approaches the identity matrix as much as possible.
Thus, by determining the actual results of P1-P9, it can be ensured that the new actual display parameters (i.e. the updated actual display parameters corresponding to the modified input parameters) obtained after the modified R ', G ' or B ' is input are closer to the target display parameters, and the monitor parameters can be corrected.
