Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 inventive step, are within the scope of the present disclosure.
The information processing method provided by the embodiment of the present application is applied to an electronic device (for convenience of description, denoted as an electronic device a), which has a display screen, for example, the electronic device may include, but is not limited to, any of the following: a notebook computer, a desktop computer, a computer with a computer all in one machine or any other device which has a display screen and needs color correction for the display screen. The information processing method provided by the embodiment of the application is used for carrying out color correction on the display screen of the electronic equipment.
Fig. 1a is a schematic diagram illustrating a basic idea of an information processing method according to an embodiment of the present application. The basic idea of the information processing method provided by the embodiment of the application is as follows: the method comprises the steps of acquiring a first image for a color chart through an image acquisition device (for convenience of description, recorded as an image acquisition device B), displaying the first image through a display screen of electronic equipment A, acquiring a second image for the display screen through the same image acquisition device B, and carrying out color correction on the display screen according to the first image and the second image.
Based on the foregoing basic ideas, an implementation flowchart of an information processing method provided in an embodiment of the present application is shown in fig. 1b, and may include:
step S101: and obtaining a first image, wherein the first image is acquired by the image acquisition device B aiming at the color chip, and the number of color blocks in the color chip is larger than or equal to the target value.
The image capturing device B may be a common device capable of capturing images, such as a mobile phone, a camera, and the like. After the image acquisition device B acquires the first image aiming at the color card, the first image is transmitted to the electronic equipment A needing to correct the color of the display screen, so that the electronic equipment A obtains the first image.
In order to prevent the color of the color card from being oxidized and color-shifted in the air, a transparent film may be attached to one side of the color card where the color block is displayed, or an isolation coating may be sprayed on the side of the color card, so in this embodiment of the application, the color card is a color card attached with a transparent film, or a color card sprayed with an isolation coating. The cost of the color card can be controlled below 10, and compared with the price of 4000 of a professional screen corrector, the cost is greatly reduced.
Step S102: the first image is displayed through the display screen.
After the electronic device A obtains the first image, the first image is displayed through a display screen of the electronic device A. The electronic device a may automatically display the first image after obtaining the first image, or display the first image after the user triggers a display instruction for the first image.
Step S103: and acquiring a second image, wherein the second image is acquired by the image acquisition device B aiming at the first image displayed by the display screen.
After the first image is displayed on the display screen, the image acquisition device B acquires the first image displayed on the display screen to obtain a second image, and the image acquisition device B sends the acquired second image to the electronic equipment A, so that the electronic equipment A obtains the second image.
Step S104: and carrying out color correction on the display screen according to the first image and the second image.
After the electronic device a obtains the first image and the second image, the display screen may be color corrected according to a color difference between the first image and the second image.
According to the information processing method, the first image acquired by the image acquisition device aiming at the color card is displayed through the display screen of the electronic equipment, the second image is acquired by the same acquisition device aiming at the display screen, and then color correction is carried out on the display screen through the first image and the second image.
As shown in fig. 2a, an exemplary graph of an association relationship between a display screen output image of a mobile phone provided in the embodiment of the present application and a plurality of color blocks in a standard image in a two-dimensional color space is provided by image quality analysis software. The small squares and the small circles which are connected in a straight line correspond to the same color block in the standard image and the display screen output image, and the color of the image output by the display screen is different from the standard color. The text in the lower left corner of the figure is an illustration of the image quality analysis software. The first line of characters on the upper right corner in the figure represents the saturation of an image output by the display screen, and the second line to the fourth line represent the mean value and the maximum value of errors of the color of the image output by the display screen and the standard color in a two-dimensional color space, which are calculated by image quality analysis software according to three different error calculation methods. Taking the fourth row as an example, the average value of errors in the two-dimensional color space between the output image of the display screen obtained by calculation by the error calculation method corresponding to the fourth row and the plurality of color blocks in the standard image is 22.2, and the maximum error is 53.7.
In an alternative embodiment, the flowchart of implementing color correction on the display screen according to the first image and the second image as shown in fig. 2b may include:
step S201: and obtaining the color offset value of the same color block in the first image and the second image.
Optionally, a difference between coordinates of colors of the color patches Si in the first image and the second image in the color space may be calculated corresponding to any color patch in the color card (for convenience of description, the ith color patch in the color patches is denoted as a color patch Si), and the difference may be used as a color offset value of the color patch Si in the first image and the second image.
Alternatively, the color of the center pixel of the color patch Si may be used as the color of the color patch Si, or the average value of the colors of all the pixels of the color patch Si may be used as the color of the color patch Si, or the average value of the colors of the center pixel of the color patch Si and the pixels of the preset number around the center pixel may be used as the color of the color patch Si.
The color is usually characterized By the values of three color channels of red (R), green (G), and blue (B), assuming that the color of the color patch Si in the first image is R1G1B1, the coordinates thereof in the color space are (Rx1, Ry1), (Gx1, Gy1), (Bx1, By1), the color of the color patch Si in the second image is R2G2B2, the coordinates thereof in the color space are (Rx2, Ry2), (Gx2, Gy2), (Bx2, By2), and the color offset value of the color patch Si in the first image and the second image is the offset value of the color patch Si in each color channel in the first image and the second image. The color offset Δ R of the color patch Si in the first image and the second image in the R channel, the color offset Δ G in the G channel, and the color offset Δ B in the B channel can be expressed by the following formulas:
Δr＝[(Rx2-Rx1)2+(Ry2-Ry1)2]1/2
Δg＝[(Gx2-Gx1)2+(Gy2-Gy1)2]1/2
Δb＝[(Bx2-Bx1)2+(By2-By1)2]1/2
in the above example, the color space is taken as a two-dimensional space for explanation, in practical application, the color space may also be a three-dimensional space, in which case, the color of the color patch Si in the first image is R1G1B1, the coordinates of the color patch Si in the color space are (Rx1, Ry1, Rz1), (Gx1, Gy1, Gz1), (Bx1, By1, Bz1), the color of the color patch Si in the second image is R2G2B2, the coordinates of the color patch Si in the color space are (Rx2, Ry2, Rz2), (Gx2, Gy2, Gz2), (Bx2, By2, Bz2), and the color offset Δ R of the color patch Si in the R channel, the color offset Δ G in the G channel, and the color offset Δ B in the B channel in the first image and the second image may be expressed as:
Δr＝[(Rx2-Rx1)2+(Ry2-Ry1)2+(Rz2-Rz1)2]1/2
Δg＝[(Gx2-Gx1)2+(Gy2-Gy1)2+(Gz2-Gz1)2]1/2
Δb＝[(Bx2-Bx1)2+(By2-By1)2+(Bz2-Bz1)2]1/2
step S202: and carrying out color correction on the display screen according to the color offset values of the color blocks in the first image and the second image.
In an electronic device with a display screen, the electronic device usually has its own Color management scheme to perform Color management on the electronic device, where the electronic device mainly performs Color management on the display screen through an ICC Profile in the Color management scheme, as shown in fig. 3a, which is an exemplary diagram of a Profile in the Color management scheme in the electronic device provided in the embodiment of the present application, in which an "sRGB Color Space Profile" file in the ICC Profile is used to manage colors of the display screen, and a portion related to an offset parameter in the file is shown in fig. 3b, and an exemplary diagram related to the offset parameter in the "sRGB Color Space Profile" file provided in the embodiment of the present application is shown in fig. 3 b. The offset parameter in this file is used to describe the offset value of the color of each pixel of the display screen from the standard color. In the example of fig. 3b, rows 4-6 represent three channels for one color, where the red channel corresponds to xyz, the corresponding offset value is 536, the green channel corresponds to xyz, the corresponding offset value is 556, the blue channel corresponds to bXYZ, and the corresponding offset value is 576. When a plurality of colors are corrected, offset values corresponding to other colors can be added in the file.
Since each color that can be displayed on the display screen is standard when the electronic device is just shipped from a factory, the offset value between each color of the display screen in the electronic device and the standard color is 0 when the electronic device is shipped from the factory, that is, the value of the offset parameter is 0.
In the embodiment of the application, after the color offset values of the color blocks in the first image and the second image are obtained, the color offset values corresponding to the colors in the configuration file in the electronic device a are updated according to the color offset values of the color blocks in the first image and the second image.
Therefore, when the electronic device A reuses the configuration file to perform color management on the display screen, the color of the display screen can be corrected.
In an optional embodiment, an implementation flowchart for updating color offset values corresponding to colors in a configuration file in an electronic device to which a display screen belongs according to color offset values of color patches in a first image and a second image is shown in fig. 4, and may include:
step S401: all colors which can be displayed by a display screen are averagely divided into N color sections, and the N color sections comprise colors of color blocks in a color card.
Optionally, all colors that can be displayed by the display screen may be averagely divided into N color segments according to standard color cards of different specifications. For example, all colors that can be displayed by the display screen are averagely divided into 24 color segments according to a 24-color standard color card, or all colors that can be displayed by the display screen are averagely divided into 64 color segments according to a 64-color standard color card, or all colors that can be displayed by the display screen are averagely divided into 256 color segments according to a 256-color standard color card, and so on.
The value of N may be equal to or greater than the number of color blocks in the color chart.
Step S402: and for each color block, replacing the color offset value corresponding to each color in the color section to which the color of the color block belongs with the color offset value of the color block.
In this embodiment, for each color block, a color segment closest to the color of the color block may be determined from the N color segments as a color segment to which the color of the color block belongs, and then the color offset value corresponding to each color in the color segment in the configuration file is replaced with the color offset value of the color block.
When the value of N is equal to the number of color patches in the color chart, the color patches and the color segments are usually in a one-to-one correspondence relationship, that is, the N color segments include the colors of all the color patches in the color chart. At this time, the color offset values corresponding to the respective colors in the configuration file may be updated.
When the value of N is greater than the number of color patches of the color card, the color patches may correspond to part of the color segments in the N color patches one to one, and if the number of color patches in the color card is M, the color patches may correspond to M color segments in the N color patches one to one, that is, the N color segments include colors not included in the color card in addition to the colors of the color patches in the color card. At this time, only the color offset values corresponding to the M color segments (corresponding to the color patches in the color card one-to-one) in the configuration file may be updated.
In an alternative embodiment, in order to ensure the accuracy of color correction on the display screen, the number of color patches in the color chart may be greater than or equal to 24. The larger the number of color patches in a patch, the higher the color correction accuracy, but the larger the calculation amount.
The size of the color card is not required, and the color card can be very small, such as 3cm multiplied by 3 cm.
The color chart in the present application may be a standard color chart, such as a 24 color standard color, or a 64 color standard color chart, etc.
In an alternative embodiment, the first image is an image of a lossless format acquired by the image acquisition device B for the color chart;
the second image is an image in a lossless format captured by the image capturing device B for the first image displayed on the display screen.
The lossless format image may include, but is not limited to, any one of the following formats: RAW images, DNG images, and so on.
In an optional embodiment, when the image capturing device B captures a second image of the first image displayed on the display screen, a light shield is disposed at an edge of the display screen, so as to prevent light around the display screen from irradiating the display screen, so that a certain color block is seriously reflected, the color block looks white, and the color correction accuracy is reduced. As shown in the electronic device a in fig. 1a, in this example, the light shield includes three directional baffles for blocking light from above the display screen and light from left and right sides, respectively, and the lower side of the light shield is usually not provided with a light source, so that the light shield can be directly opposite to the display screen without blocking. Alternatively, the directional baffles of the light shield may extend 20cm in the direction of the display screen.
In addition, in order to further improve the color correction accuracy of the display screen, the color chart and the display screen are in the same environment when the color chart and the display screen are photographed. Based on this, when gathering first image to the colour chip through image acquisition device B, the colour chip is located the display screen and is located the region, for example, can paste the colour chip in certain region of display screen, wait to shoot and finish, take away the colour chip from the display screen again.
