Title
(EN) PRODUCT COLOR CORRECTING METHOD AND PRODUCT COLOR CORRECTING SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE CORRECTION DE COULEUR DE PRODUIT
Abstract
(EN)
The present invention relates to a product color correcting method and a product color correcting system. The product color correcting method comprises: an acquiring step to acquire current color parameters of a product by using a mobile terminal to photograph the product; a comparing step to obtain a comparison result by comparing the current color parameters of the product with target color parameters of the product, and to output the comparison result as a color parameter bias between the target color parameters of the product and the current color parameters of the product; and, a correcting step to acquire, based on a first corresponding relationship between a pre-stored color parameter bias and a correction to the formulation for the color of the product, the correction to the formulation for the color of the product corresponding to the color parameter bias output in the comparing step. According to the present invention, it is capable of shortening the cycle of formulation update or color calibration and change so as to meet the requirement of fast generation.

La présente invention concerne un procédé de correction de couleur de produit et un système de correction de couleur de produit. Le procédé de correction de couleur de produit comprend : une étape d'acquisition consistant à acquérir des paramètres de couleur actuels d'un produit en utilisant un terminal mobile pour photographier le produit; une étape de comparaison consistant à obtenir un résultat de comparaison par la comparaison des paramètres de couleur actuels du produit avec des paramètres de couleur cibles du produit, et à délivrer le résultat de comparaison sous la forme d'un biais de paramètre de couleur entre les paramètres de couleur cibles du produit et les paramètres de couleur actuels du produit; et, une étape de correction consistant à acquérir, sur la base d'une première relation correspondante entre un biais de paramètre de couleur préalablement stocké et une correction de la formulation pour la couleur du produit, la correction à la formulation pour la couleur du produit correspondant au biais de paramètre de couleur délivré dans l'étape de comparaison. Selon la présente invention, il est possible de raccourcir le cycle de mise à jour d'une formulation ou d'étalonnage et de changement d'une couleur de façon à permettre une génération rapide.
