Description

Method and display for simulating display characteristics of display

The present invention relates to a method and display for simulating display characteristics of a display, and more particularly to a method of simulating display characteristics of a color display and a display using the same.

The display is one of the most important information delivery media for modern humans, while the color display uses a color model to describe the colors seen and used in digital images. The color model describes the colors seen and used in the digital image. Each color model (such as a color model such as RGB, CMYK, or HSB) is a way to describe and classify colors. The color space is another type of color model with a specific color gamut. The various devices in the imaging workflow (such as monitors, scanners, printers, and digital cameras) operate in different color spaces and each have a different color gamut. Some colors within the color gamut of the display will not be within the color gamut of the inkjet printer; vice versa.

In the prior art, to ensure that the color gamut of the display conforms to specific specifications (eg, Adobe RGB gamut, sRGB color gamut), the display typically requires color correction to ensure the color accuracy of the image it displays. Please refer to FIG. 1. FIG. 1 is a schematic diagram of color correction of the display 10 according to the prior art. When the color correction of the display 10 is performed, the optical characteristics of the display 10 are first measured by the measurement and correction system 20, and then the color correction of the display 10 is performed according to the measured optical characteristics of the display 10, so that the The color corrected display 10 can conform to a particular color specification. However, such a color correction method can only make the display 10 conform to a specific color specification, but it does not allow the user to see the color performance of the image on other devices (such as a mobile phone screen or other display device) on the display 10. This is not convenient for professionals with special requirements for color.
