Abstract

В заявке описан способ формирования комбинированного изображения из изображения переднего плана (FG+BS), воспроизводящего объект на одноцветном фоне, и изображения заднего плана (BG). В этом способе для каждого элемента растра изображения переднего плана (FG) на основании, во-первых, цветовых координат данного элемента растра и, во-вторых, заданных цветовых координат, передающих цветосочетание одноцветного фона, рассчитывают управляющий сигнал, определяющий принадлежность элемента растра либо к объекту, либо к одноцветному фону, и в зависимости от указанного управляющего сигнала на основании цветовых координат соответствующего элемента растра либо изображения переднего плана (FG), либо изображения заднего плана (BG) рассчитывают цветовые координаты комбинированного изображения (КВ) в каждом элементе растра, причем для каждого элемента растра комбинированного изображения (КВ) на основании цветовых координат соответствующего элемента растра изображения переднего плана (FG) и/или изображения заднего плана (BG) рассчитывают значения коррекции (L, R, S, Т) и в соответствии с этими значениями коррекции изменяют цветовые координаты комбинированного изображения (КВ) в каждом элементе растра.Международная заявка была опубликована вместе с отчетом о международном поиске.
