Abstract

UNA CAMARA DE VIDEO TIENE UN CUERPO (1) CON UN FORMADOR DE IMAGENES EN SU INTERIOR PARA PROPORCIONAR UNA SEÑAL DE VIDEO EN RESPUESTA A LA PROYECCION DE UNA IMAGEN LUMINOSA EN EL MISMO POR MEDIO DE UN DISPOSITIVO DE LENTES INTERCAMBIABLES (2) MONTADAS DE FORMA EXTRAIBLE EN EL CUERPO DE LA CAMARA (1), Y UN PRIMER Y UN SEGUNDO MICROORDENADORES (3, 4) EN EL CUERPO DE LA CAMARA (1) Y EL DISPOSITIVO DE LENTE (2), RESPECTIVAMENTE, QUE SE ENCUENTRAN PROGRAMADOS DE FORMA QUE EN UNA SECUENCIA DE COMUNICACION INICIAL ENTRE ELLOS UNA VEZ MONTADO EL DISPOSITIVO DE LENTE SELECCIONADO (2) EN EL CUERPO DE LA CAMARA (1), EL SEGUNDO MICROORDENADOR (4) TRANSMITE DATOS DE LAS CARACTERISTICAS OPTICAS PARA EL DISPOSITIVO DE LENTE RESPECTIVO (2) AL PRIMER MICROORDENADOR (3) EN RESPUESTA A UNA SEÑAL DE SOLICITUD DE TRANSMISION DE DATOS DE ESTE ULTIMO, Y POSTERIORMENTE DE FORMA QUE, EN UNA SECUENCIA DE COMUNICACION DE CONTROL QUE SIGUE A LA SECUENCIA DE COMUNICACION INICIAL, EL PRIMER MICROORDENADOR (3) TRANSMITE UNA SEÑAL DE CONTROL AL SEGUNDO MICROORDENADOR (4) EN BASE A LOS DATOS DE LAS CARACTERISTICAS OPTICAS RECIBIDOS Y LA SEÑAL DE ESTADO CONTROLADO PROPORCIONADA AL PRIMER MICROORDENADOR (2) DESDE EL SEGUNDO MICROORDENADOR (4). ADEMAS, AL MONTAR EL DISPOSITIVO DE LENTE SELECCIONADO (2) EN EL CUERPO DE LA CAMARA (1), SE DETECTA LA EXISTENCIA DE LAS CONEXIONES ELECTRICAS ADECUADAS ENTRE ELLOS.
