Embodiment

[0041] figure 1 It is a flowchart of the construction of the optimization model in the embodiment of the present invention;

[0042] Such as figure 1 As shown, the construction of an optimized color appearance model in a high-brightness environment has the following steps:

[0043] The first step: select the display device and the experimental environment settings;

[0044] Step 1-1: Selection of display: select an advanced professional-grade display, choose EIZO CG246 display in this embodiment, and select a host computer with a 10-bit graphics card that is matched with the display;

[0045] Step 1-2: Experiment layout: as figure 2 As shown, in a standard dark room, the display screen is divided into two parts, left and right, for subjective visual matching experiments. The original stimulus color and the matching color block are both 4cm*4cm, and the eyes of the subjective experimenter and the color block form a 2-degree viewing angle. , the observation distance is 115c...

Abstract

The invention discloses a color appearance model refine-bri CIECAM02 suitable for a high-luminance environment. The model is built with a standard color appearance model building method. Firstly, corresponding color data in the high-luminance environment is obtained, and performance of an existing color appearance model is analyzed and checked according to the acquired corresponding color data; the color appearance model refine-bri CIECAM02 suitable for the high-luminance environment is built on the basis of an analysis result. The experimental result indicates that compared with color appearance models CIECAM02 and refineCIECAM02, the model has the advantages that prediction accuracy is high, the experimental process of acquiring experimental data is repeatable during model building and the like, and by means of the advantages, verification and further optimization of the model are facilitated.

Description

technical field [0001] The invention relates to the field of color display reproduction and color management in a high brightness environment, in particular to a color appearance model in a brightness environment. Background technique [0002] With the wide use of various display devices, such as large screens in airports, outdoor advertising screens, promotional displays in shopping malls, various smart mobile terminals, etc., the ambient brightness of display devices is also undergoing significant changes. Ordinary computer-controlled monitors are generally used under the brightness of the normal office environment, but the brightness of the above-mentioned display devices can change from the darkest to the dark color of the night, and the brightest to the high-brightness environment at noon under the sun. . Ambient light has a great influence on the visual experience of stimulating colors. The visual experience of the same stimulating color is different under different a...
