Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The terms "first," "second," "third," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be implemented in other sequences than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, many intelligent devices in the market are provided with a screen mirroring function, screen mirroring refers to that a picture displayed by a current screen at a screen mirroring initiating end is displayed on a larger screen, a main body of the screen mirroring initiating end is generally an intelligent terminal such as a mobile phone and a tablet, and a main body of the larger screen is generally a display device with the larger screen. For example, the contents of documents, videos, live broadcasts, games and the like in the mobile phone are put on the smart television for synchronous display through the screen mirroring function.
However, the display screen at the screen image initiating end and the display screen at the screen image receiving end often belong to different types of display screens, the adopted manufacturing process and the tuning and teaching standards are different, and even if the display screens are of the same type, the tuning and teaching capabilities of various manufacturers can also influence the color presentation of the display screens. Therefore, when the same display content is displayed, the display screen at the receiving end of the screen image may show inconsistent color with respect to the display screen at the initiating end of the screen image, specifically, the problem may be shown as color cast, supersaturation, insufficient saturation, or dark hue.
In the prior art, if a display device is required to correct its own color problem, a professional color corrector needs to be used to perform color calibration according to the specified standard of the display device, that is, color calibration is realized through interactive operation between the color corrector and the display device. However, there is no corresponding solution for the requirement that the screen image receiving end of the screen image performs color calibration according to the color standard of the screen image initiating end. Meanwhile, the price of the color corrector is high, and the color corrector has relevant requirements on knowledge storage of users, so that the color calibration of the display equipment at the screen image receiving end is realized only through interactive operation between the screen image receiving end and the screen image initiating end without the help of the color corrector.
Fig. 1 is a schematic flowchart of a first embodiment of a color calibration method for a display device provided in the present application, including steps 101 to 104:
101. and receiving a display instruction sent by a screen image initiating end, wherein the display instruction comprises a color chip value of a target color.
The screen image receiving end of the embodiment can be a large-screen display device such as a television, the screen image initiating end can be an intelligent terminal with a relatively small screen such as a mobile phone and a tablet, and the intelligent terminal can be in communication connection with the screen image receiving end, and the connection mode can be a wireless communication mode, for example, wi-Fi (wireless network communication technology), or can be in communication connection in a wired data line mode.
Through step 101, the screen image receiving end receives a display instruction sent by the screen image initiating end, where the display instruction includes a target color target value to be detected, and colors displayed by different display devices for the same color target value have different differences in different degrees, that is, the color display is inaccurate and needs to be calibrated. The target color can be selected according to different requirements, for example, based on the mixed light principle of the three primary optical colors (red, green, and blue), the three colors of red, green, and blue can be used as the target color, and the target color can have different representation manners corresponding to the target color, for example, a color gradation representation method, if the color depth of the display device at the screen image launching end is 8 bits, the color gradation of the display device is 256 and is represented by using coordinates (X, Y, Z), where X represents the color gradation value of red, Y represents the color gradation value of green, and Z represents the color gradation value of blue, the color gradation values of the three target colors of red, green, and blue can be represented as (255, 0), (0, 255, 0), (0, 255); alternatively, in the percentage expression, coordinates (a, B, C) are used to express a luminescence ratio of red, a luminescence ratio of green, and a luminescence ratio of blue, which is understood as a luminescence degree of one color, and for example, a luminescence ratio of red of 20% is understood as a luminescence of 20% of a maximum luminescence degree of red, and a target color of red, green, and blue may be expressed as (100%, 0%), (0%, 100%, 0%), (0%, 0%, 100%).
In addition, because the color depths adopted by the display devices of the screen image receiving end and the screen image initiating end may be different, the screen image receiving end or the screen image initiating end can also convert the color chip value of the color gradation representation into the color chip value of the percentile representation, so that the color chip values can be commonly used on the two. In this embodiment, the type and number of the selected target color and the representing method of the color card value are not limited.
Meanwhile, the screen image initiating terminal needs to detect the display colors corresponding to the target colors one by one, namely the screen image initiating terminal needs to inform the screen image receiving terminal of what kind of target color detection needs to be performed at this moment, so that the screen image receiving terminal displays the display colors of the target colors to receive detection.
102. And displaying the display color of the color card value according to the display instruction so that the screen image initiating end determines the teaching data according to the detection parameters of the display color.
Since the colors displayed by different display devices for the same color card value are different, i.e. the color display is not accurate enough, the color calibration is needed. In step 102, the screen image receiving end receives the display instruction from the screen image initiating end, and then displays the color chip value included in the display instruction, and the displayed display color can be detected by the screen image initiating end, and obtains the detection parameter, so as to further enable the screen image initiating end to determine the teaching data.
For example, if the screen image initiating terminal is equipped with an ambient light sensor, the ambient light sensor can be used to detect a detection parameter of brightness, so as to make a difference with a standard value of a brightness value of a target color stored in advance in the screen image initiating terminal, to determine that the target color is present on the screen image receiving terminal, an adjustment of the brightness value needs to be made, and then the difference of the brightness is the tuning data. In practical application, other corresponding sensors can be further equipped on the screen image initiating terminal to perform corresponding detection on the display color.
Or, a multispectral sensor is configured on the screen image initiating end, the multispectral sensor can be used to detect Correlated color temperature (CCT for short, correlated color temperature) in the environment, the screen image initiating end compares the detected Correlated color temperature value of the display color with the Correlated color temperature value of the target color by detecting the Correlated color temperature value of the display color at the screen image receiving end, and further determines the adjustment that needs to be made on the screen image receiving end for the target color, that is, determines the tuning data, and the specific determination mode and principle of the tuning data can be as follows:
the color calibration method of the embodiment of the present application can be based on the principle of mixed light of the three primary optical colors (red, green, and blue), i.e., any color of the display device can be obtained by mixing red, green, and blue in different proportions. Therefore, the embodiment of the present application selects color calibration for red, green, blue, white, black and gray levels, and as an example, selects detection for the following 9 target colors, including red, green, blue, white, black and gray levels of four levels, and the color chip value of each target color can be expressed as follows by the percentage coordinate representation described above: (100%, 0%, 0%), (0%, 100%, 0%), (0%, 0%, 100%), (100%, 100%, 100%), (0%, 0%, 0%), (20%, 20%, 20%), (40%, 40%, 40%), (60%, 60%, 60%) and (80%, 80%, 80%); the color depth can also be expressed by a coordinate expression method, for example, when the color depth is 8 bits, the color chip values corresponding to the above 9 target colors can be expressed as: (255, 0), (0, 255, 0), (0, 255), (255 ), (0, 0), (51, 51, 51), (102 ), (153, 153) and (204 ), the present embodiment is not limited to the type and number of the selected specific target colors, and the representation method.
The screen image initiating terminal detects the relevant color temperature values of the 9 target colors and compares the detected values with the relevant color temperature values of the 9 target colors, and then determines the teaching data, and the specific mode can be as follows: aiming at three target colors of red, green and blue, the types of the tuning and teaching data are chroma and saturation, namely, the adjustment values of the chroma and the saturation are used as the tuning and teaching data, so that the related color temperature value of the display color is close to the related color temperature value of the target color, and the color calibration is realized; for the target color of white, the type of the tuning data can be contrast, that is, the adjustment value of the contrast is used as the tuning data; for the target color of black, the type of the training data is brightness, that is, the adjustment value of the brightness is used as the training data; for the gray scales of four levels, because the gray scales are color lights mixed from three primary colors, which are not only simple superposition of the three primary colors, i.e. not simple linear relationship, further fine adjustment needs to be performed on the data of the contrast and brightness of each three primary color in the mixed color lights, i.e. the type of the training data is the contrast and brightness of the three primary colors of red, green and blue, i.e. the gray scale of each level has 6 numerical values and needs to be adjusted.
In this embodiment, the tuning and teaching data may be directly determined according to the detection data of the display color, for example, the brightness value of the display color is detected, and the difference is made between the detected brightness value and the brightness value that should be presented of the target color, that is, the difference may be used as the tuning and teaching data, or the correlated color temperature value of the display color is detected, and the difference is made between the detected brightness value and the correlated color temperature value that should be presented of the target color, and the parameter type and the parameter variation value that should be adjusted for the display color corresponding to each target color are obtained by looking up the table, that is, the comparison table is already stored at the screen image initiating end, and then the tuning and teaching data can be obtained by looking up the table.
In this embodiment, the detection result gradually approaches the value that the target color should be presented in a manner of debugging the display parameters of the display color, that is, the appropriate tuning data is gradually found in a manner of debugging. For example, the related color temperature value of red is detected, the difference is made between the related color temperature value of red and the related color temperature value that red should present, the difference is found to be larger than the related color temperature value that should present, then the values of the chroma and the saturation of red at the receiving end of the screen image are gradually reduced to make the red approach the related color temperature value that should present, and when the red is approximately equal to the related color temperature value that should present, the difference of chroma and the difference of saturation in the debugging process can be used as the tuning data.
In the above example, the number and the type of the target colors and the type of the training data for the training data of each target color are only examples, and in practical applications, the number and the type of the target colors and the type of the training data for each target color may be determined according to practical needs, which is not limited by the embodiment of the present application.
Meanwhile, after the screen mirror image initiating end determines the tuning and teaching data aiming at each selected target color, the tuning and teaching data of other mixed colored light can be obtained through linear fitting and other modes, and then all the tuning and teaching data are sent to the screen mirror image receiving end, so that the screen mirror image receiving end can carry out color calibration.
103. And receiving the training data sent by the screen image initiating terminal.
The screen image receiving end establishes communication connection with the screen image initiating end in a wireless or wired manner, and the screen image receiving end can receive all the teaching data and continue to execute step 104.
104. And calibrating the color of the display equipment according to the training data.
After receiving all the tuning and teaching data, the screen mirror image receiving end can calibrate the color of the display device according to the content of the tuning and teaching data, where the content of the tuning and teaching data includes tuning and teaching data types for a plurality of colors and values that need to be adjusted, where the tuning and teaching data types may be the types commonly used for color calibration in the field, such as the chromaticity, the brightness, the contrast, and the saturation, and the like, and the embodiment of the present application does not limit this.
The application provides a display device's color calibration method can be applied to the screen image receiving terminal, when the screen image receiving terminal receives the demonstration instruction that the screen image initiating terminal sent, begin to show the display colour that the colour chip value that contains in the demonstration instruction corresponds to the cooperation screen image initiating terminal is one by one to the detection of the display colour that each target colour corresponds, the screen image initiating terminal can confirm the teaching data according to the detection parameter of this display colour, promptly after each display colour of screen image initiating terminal to the screen image receiving terminal all accomplished the detection, can obtain a set of teaching data, send the teaching data for the screen image receiving terminal, after the screen image receiving terminal received the teaching data, can carry out display device's color calibration according to the teaching data. According to the embodiment, the display equipment at the screen mirroring receiving end can carry out color calibration according to the color standard of the display equipment at the screen mirroring initiating end only through interactive operation between the screen mirroring receiving end and the screen mirroring initiating end without other expensive color calibration equipment.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a second embodiment of a color calibration method for a display device according to the present application, where the method is applied to a screen image receiving end, and includes steps 201 to 208:
201. and determining a display area, wherein the display area is used for displaying the display color, and the range of the display area is slightly larger than the frame of the starting end of the screen mirror image.
Based on the principle that the same color light has the same correlated color temperature value, the embodiment determines appropriate teaching data to complete color calibration of the display color by detecting whether the correlated color temperature value of the display color is consistent with the correlated color temperature value of the target color.
The multispectral sensor is arranged at the screen image initiating end of the embodiment and used for detecting the related color temperature value of the display color presented by the screen image receiving end, and in order to enable the detection data of the related color temperature value to be more accurate, the multispectral sensor needs to be aligned to the light rays in a limited range as much as possible.
The embodiment of the application does not limit the specific position of the display area, and the display area can be located at any position on the display device of the screen mirror image receiving end, and meanwhile, the embodiment of the application does not limit the shape of the display area, for example, the shape of the display area can be regular or irregular shapes such as a square shape, a smiling face figure, a dot-matrix figure and the like.
It is simultaneously from top to bottom visible, the size of display area can be decided according to the frame size of screen image initiating terminal, consequently, in practical application, the equipment information of screen image initiating terminal can be acquireed earlier to the screen image receiving terminal, contains the frame size of screen image initiating terminal in the equipment information, shows a display area slightly bigger than this frame size then on the display device of screen image receiving terminal, in order to be used for showing show the look. Or, because the screen image initiating end is usually a smart phone, the size of the frame of the smart phone on the market can be counted, the value of the size of the frame of the smart phone with the largest frame is found, and then a value slightly larger than the largest frame is set as the constant size value of the display area, so that the screen image receiving end can display the display color.
The display color is presented by setting the display area with the limited size, so that the accuracy of the detection result of the related color temperature value of the display color is improved, and the accuracy of color calibration is further improved.
202. And receiving a display instruction sent by a screen image initiating end, wherein the display instruction comprises a color chip value of a target color.

The screen image initiating terminal of the embodiment needs to be equipped with a multispectral sensor for detecting a relevant color temperature value of a display color presented by the screen image receiving terminal, a threshold range is set for the relevant color temperature value of each target color by comparing the relevant color temperature value of the display color with a relevant color temperature value of a target color stored in the screen image initiating terminal, if the relevant color temperature value of the display color is within the threshold range of the relevant color temperature value of the target color, a change value of a display parameter included in a debugging instruction is 0, if the relevant color temperature value of the display color presented at the screen image receiving terminal does not fall within the threshold range, the display parameter of the display color of the target color needs to be adjusted, namely, the debugging instruction is sent to the screen image receiving terminal until the relevant color temperature value of the display color falls within the threshold range, after the screen image receiving terminal receives the debugging instruction, the corresponding display parameter of the display color according to the debugging instruction, so that the relevant color temperature value of the display color gradually approaches the relevant color temperature value of the target color, and the relevant color temperature value of the screen image initiating terminal is determined as a suitable color contrast parameter for the screen image.
As an example, the target color is selected from the following 9 colors, including red, green, blue, white, black, and four levels of gray scale, and the target color has a color chip value expressed by the percentage coordinate expression as follows: (100%, 0%, 0%), (0%, 100%, 0%), (0%, 0%, 100%), (100%, 100%, 100%), (0%, 0%, 0%), (20%, 20%, 20%), (40%, 40%, 40%), (60%, 60%, 60%) and (80%, 80%, 80%); the color depth can also be expressed by a coordinate expression method, for example, when the color depth is 8 bits, the color chip values corresponding to the above 9 target colors can be expressed as: (255, 0), (0, 255, 0), (0, 255), (255, 0), (51, 51, 51), (102 ), (153, 153) and (204 ), the present embodiment is not limited to the type and number of the selected specific target colors, and the representation method.
Specifically, for the display colors corresponding to the three target colors, namely red, green and blue, the debugging instruction to be obtained should include variation values of chromaticity and saturation so that the relevant color temperature values of the display colors gradually approach the relevant color temperature values of the target colors, thereby helping the screen mirroring initiating end to determine appropriate tuning data; for the target color of white, the debugging instruction needing to be acquired should contain the change value of contrast; for a target color of black, the debugging instruction needing to be acquired should include a brightness change value; for the gray scale of four levels, because the gray scale is the color light mixed from three primary colors, it is not only the simple superposition of the three primary colors, i.e. it is not the simple linear relationship, so it is necessary to further fine-tune the data of the contrast and brightness of each primary color in the mixed color light, i.e. the change value of the contrast and the change value of the brightness of the three primary colors of red, green and blue should be included in the debugging command.
In the above example, the type of the display parameter that needs to be adjusted for the display color of each target color is only an example, and in practical applications, the type and the number of the target colors and the type of the display parameter that needs to be adjusted for the display color of each target color may be determined according to actual needs, which is not limited in the embodiment of the present application.
