Title:
OBJECT PREFERENCE MEMORY COLOR OBTAINING METHOD AND PREFERENCE MEMORY COLOR STANDARD COLOR CARD
Document Type and Number:
WIPO Patent Application WO/2022/242608
Kind Code:
A1
Abstract:
Disclosed in the present invention are an object preference memory color obtaining method and a preference memory color standard color card. The method comprises: collecting an initial image of a target object having a representative memory color and a spectral reflectance distribution curve of an actually measured surface color of the target object; rendering the initial image to obtain a group of experimental images; obtaining evaluation data of experimental image-based memory color preference of a subject; according to the evaluation data, obtaining coordinate values of a preference memory color by using an elliptical memory color model; in addition, selecting a pigment combination of color blocks by means of a spectral reflectance distribution curve of an actually measured memory object; and then obtaining a color formula of the color block of the preference memory color of the experiment by means of the combination, so as to obtain a memory-color color card. The obtained color card can be applied to evaluation of preference memory colors on an electronic display device and testing of the quality of a picture imaged by a digital camera and white balance, and can also be used for evaluating the color development quality of a light source in lighting industry.
