Title (EN) IMAGE PROCESSING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT D'IMAGE
(ZH) 一种图像处理方法及装置
Abstract:
(EN) The present invention provides an image processing method and device, said method comprising: performing, according to a first function f1(x), image processing of an RGB color space component point Ai(ri, gi, bi) of an initial image, and obtaining A0(r0, g0, b0)=f1(xi); Performing, according to a second function f2(x), image processing of a point Ai(ri, gi, bi) in the initial image, and obtaining a processed saturation S0=f2(xi); making f2(xi) equal to 1, and obtaining the point A0(r0, g0, b0); if max(r0, g0, b0)≤1, performing image processing of the point Ai in the RGB color space, and if max(r0, g0, b0)>1, converting the point Ai to a CMY color space for image processing.
(FR) La présente invention concerne un procédé et un dispositif de traitement d'image, ledit procédé consistant à : effectuer, selon une première fonction f1(x), le traitement d'image d'un point de composante d'espace de couleur RVB Ai(ri, gi, bi) d'une image initiale, et obtenir A0(r0, g0, b0) = f1(xi) ; effectuer, selon une deuxième fonction f2(x), le traitement d'image d'un point Ai(ri, gi, bi) dans l'image initiale, et obtenir une saturation traitée S0 = f2(xi) ; rendre la valeur de f2(xi) égale à 1, et obtenir le point A0(r0, g0, b0) ; si max(r0, g0, b0) ≤ 1, effectuer le traitement d'image du point Ai dans l'espace de couleur RVB, et si max(r0, g0, b0) > 1, convertir le point Ai dans un espace de couleur CMY pour le traitement d'image.
(ZH) 本发明提供了一种图像处理方法及装置,根据第一函数f1(x)对原图像的RGB颜色空间分量点Ai(ri,gi,bi)进行图像处理,得到A0(r0,g0,b0)=f1(xi);根据第二函数f2(x)对原图像中的某一点Ai(ri,gi,bi)进行图像处理,得到处理后的饱和度S0=f2(xi);令所述f2(xi)=1,求出点A0(r0,g0,b0),若max(r0,g0,b0)≤1,则将点Ai将在所述RGB颜色空间中进行图像处理,若max(r0,g0,b0)>1,则将点Ai转换至CMY颜色空间中进行图像处理。
