Abstract

''PROCESSO PARA COMPENSAçãO DE DEFEITOS GEOMéTRICOS EM IMAGENS DE VìDEO, E DISPOSITIVO PARA REPRESENTAçãO DE IMAGENS DE VìDEO SOBRE UMA SUPERFìCIE DE PROJEçãO''. Um dispositivo para representação de imagens de vídeo sobre uma superfície de projeção (101) sob posição oblíqua, abrangendo uma fonte de intensidade modulável (10) para emissão de um feixe de luz essencialmente paralelo para uma iluminação seq³encial de pixels da imagem de vídeo, uma unidade defletora (11, 12) para varredura do feixe de luz conforme linhas e imagens, e uma unidade de controle (17), a qual comanda tanto a modulação da intensidade para o feixe de luz, como também a respectiva deflexão (11, 12) conforme uma função, esta última obtida através de uma equalização calculada da imagem, pelo menos com referência à posição oblíqua. (Fig. 1).
