Abstract
SE DESCRIBE UN SISTEMA DE VIDEO QUE CREA UNA SOMBRA VIRTUAL DE UN OBJETO QUE SE HALLA EN PRIMER PLANO, FILMADO ANTE UNA PANTALLA DE COLOR AZUL POR MEDIO DE UNA CAMARA DE VIDEO PRINCIPAL. SE CREA LA SOMBRA VIRTUAL UTILIZANDO UNA SEGUNDA CAMARA DE VIDEO SITUADA COMO FUENTE LUMINOSA VIRTUAL. SE PROCESAN LAS IMAGENES DE AMBAS CAMARAS POR MEDIO DE UN PROCESADOR CROMATICO (CHROMA KEYING) PARA SEPARAR EL OBJETO QUE SE ENCUENTRA EN PRIMER PLANO. SE PROCESA LA IMAGEN DE VIDEO DE LA SEGUNDA CAMARA PARA CREAR LA SOMBRA VIRTUAL Y SE COMBINAN AMBAS IMAGENES CON LA IMAGEN DE FONDO. SE DESCRIBEN SISTEMAS PARA LOCALIZAR OBJETOS Y PARA GUIAR AL ACTOR, QUE PERMITEN QUE ESTE ENCUENTRE FACILMENTE SU CAMINO EN EL ESTUDIO Y QUE DIRIJA SU MIRADA SOBRE LOS OBJETOS VIRTUALES QUE APARECEN Y DESAPARECEN DEL ESTUDIO. EL SISTEMA DE GUIADO PROPORCIONA AL ACTOR LOS TIEMPOS DE LOS DIVERSOS SUCESOS QUE SE PRODUCEN EN EL ESTUDIO. LAS MARCAS ESPECIALES SON COMPLETAMENTE INVISIBLES PARA LA CAMARA Y PARA LOS TELESPECTADORES, PORQUE O BIEN SE PROYECTAN EN UN COLOR DEL PROCESO CROMATICO, O BIEN ESTAN ACTIVOS SOLAMENTE DURANTE EL BORRADO VIRTUAL DE LA CAMARA, COMO POR EJEMPLO EN EL INTERVALO DE BORRADO VERTICAL O EN EL DE BORRADO HORIZONTAL EN LOS SISTEMAS NTSC, PAL, SECAM O CUALQUIER OTRO FORMATO.
