Abstract: front page image
(EN)The present invention relates to a method of processing a digital image, the method including: (a) obtaining a plurality of images; (b) converting the plurality of images into histograms; (c) setting one of the plurality of images as a reference image and the others of the plurality of images as comparison target images; (d) matching the histogram of the reference image with the histograms of the comparison target images to produce an adjustment reference image; (e) comparing the difference between the adjustment reference image and the comparison target image for every pixel to produce a masking image; (f) synthesizing the comparison target image and the masking image to produce an adjustment comparison target image; and (g) synthesizing the reference image and the adjustment comparison target image to produce a high dynamic range (HDR) image. Accordingly, even if there is a complex motion on a subject, the present invention may obtain a clear image without an image overlap or a ghost when producing the HDR image.
(FR)La présente invention concerne un procédé de traitement d'une image numérique, le procédé comprenant : (a) l'obtention d'une pluralité d'images; (b) la conversion de la pluralité d'images en histogrammes; (c) la définition d'une image parmi la pluralité d'images en tant qu'image de référence et des autres images parmi la pluralité d'images en tant qu'images cibles de comparaison; (d) la mise en correspondance de l'histogramme de l'image de référence avec les histogrammes des images cibles de comparaison afin de produire une image de référence de réglage; (e) la comparaison de la différence entre l'image de référence de réglage et l'image cible de comparaison pour chaque pixel pour produire une image de masquage; (f) la synthèse de la comparaison de l'image cible et de l'image de masquage pour produire une image cible de comparaison de réglage; et (g) la synthèse de l'image de référence et l'image cible de comparaison de réglage pour produire une image HDR (High Dynamic Range). En conséquence, même s'il y a un mouvement complexe sur un sujet, la présente invention peut obtenir une image claire sans superposition d'images ou image fantôme lors de la production de l'image HDR.
(KO)본 발명의 일 태양에 따르면, (a) 복수의 영상을 획득하는 단계, (b) 상기 복수의 영상을 히스토그램으로 변환하는 단계, (c) 상기 복수의 영상 중 어느 하나를 기준 영상으로 나머지 영상을 비교 대상 영상으로 설정하는 단계, (d) 상기 기준 영상의 히스토그램을 상기 비교 대상 영상의 히스토그램과 매칭하여 조정 기준 영상을 생성하는 단계, (e) 상기 조정 기준 영상과 상기 비교 대상 영상의 차이를 각 픽셀마다 비교하여 마스킹 영상을 생성하는 단계, (f) 상기 비교 대상 영상과 마스킹 영상을 합성하여 조정 비교 대상 영상을 생성하는 단계, 및 (g) 상기 기준 영상과 상기 조정 비교 대상 영상을 합성하여 HDR 영상을 생성하는 단계를 포함하는 디지털 영상 처리 방법이 제공된다. 이를 통하여 본 발명은 피사체에 복잡한 움직임이 있을 경우에도 HDR(High Dynamic Range) 영상을 생성하는데 있어, 상겹침이나 고스트 현상 없이 선명한 영상을 얻을 수 있다.
