Abstract

<B>"DISPOSITIVO E PROCEDIMENTO PARA A PRODUçãO DE UMA IMAGEM COMPOSTA"<D>. Procedimento para a produção de uma imagem composta a partir de uma imagem de primeiro plano (FG+BG), a qual reproduz um objeto diante de um segundo plano monocromático, e de uma imagem de segundo plano (BG), na qual para cada elemento da retícula da imagem de primeiro plano (FG) é calculado um sinal de comando a partir dos valores cromáticos do elemento da retícula por um lado e por outro lado dos valores cromáticos estabelecidos anteriormente reprodutores da composição de cores do segundo plano monocromático, sinal este que reproduz a correspondência do elemento da retícula em relação ao objeto ou ao segundo plano monocromático e no qual os valores cromáticos da imagem composta (KB1) são calculados em cada elemento da retícula em dependência do sinal de comando a partir dos valores cromáticos do elemento da retícula correspondente da imagem de primeiro plano (FG) ou da imagem de segundo plano (BG), sendo que para cada elemento da retícula da imagem composta (KB1) são calculados valores corrigidos (L, R, S, T) a partir dos valores cromáticos do elemento da retícula correspondente da imagem de primeiro plano (FG) e/ou da imagem de segundo plano (BG) e modificados os valores cromáticos da imagem composta (KB1) em cada elemento da retícula correspondendo aos valores corrigidos.
