calibration
Calibration is an important step in color management, and by calibrating the LCD screen, it can ensure the consistency of its color performance under various conditions. During the calibration process, specialized calibration instruments such as spectrophotometers are required to measure and adjust the color temperature, brightness, contrast, etc. of the screen in order to achieve the best color performance.
Gamma curve adjustment
The gamma curve is a curve that describes the relationship between image brightness and image level. For LCD screens, adjusting the gamma curve can improve their color performance. During the adjustment process, it is necessary to use professional image processing software to optimize the color by adjusting the brightness curve.
White point correction
White point correction is achieved by adjusting the intensity ratio of the three primary colors of red, green, and blue on the screen to adjust white points. By correcting the white point, the color expression of the screen can be made more accurate and its color reproduction can be improved.
Application of Color Management Software
In addition to the above three methods, professional color management software such as DisplayCAL, CALMAN, etc. can also be used. These software can provide detailed descriptions of the color characteristics of LCD screens and offer practical color management functions such as color gamut mapping and color space conversion.
