Abstract

EN UN APARATO DE ENFOQUE AUTOMATICO DE UNA CAMARA DE VIDEO, UN PRIMER VALOR DE ENFOQUE QUE CAMBIA BRUSCAMENTE Y UN SEGUNDO VALOR DE ENFOQUE QUE CAMBIA SUAVEMENTE EN RELACION A LA POSICION DE UNA LENTE, SE DETECTAN EN RESPUESTA A UNA SEÑAL DE VIDEO OBTENIDA EN UN CIRCUITO SENSOR DE IMAGEN (4). UN CIRCUITO SELECTOR (19) SELECCIONA ALTERNATIVAMENTE EL PRIMER Y EL SEGUNDO VALORES DE ENFOQUE EN CADA CAMPO, PARA APLICARLO A CIRCUITOS DE DETECCION (20,21) DE ESTADO DE ENFOQUE, RESPECTIVAMENTE. LOS CIRCUITOS DETECTORES (20,21), JUNTO CON UN CIRCUITO DE CONTROL (10) DEL MOTOR DE ENFOQUE, EFECTUAN UNA OPERACION AUTOMATICA DE ENFOQUE MEDIANTE CONTROL ASCENDENTE. ADEMAS, UN CIRCUITO DE CALCULO (22) CALCULA LA RELACION RELATIVA DEL PRIMER VALOR DE ENFOQUE RESPECTO AL SEGUNDO. EL CIRCUITO DE CONTROL (10) DEL MOTOR DE ENFOQUE ESTABLECE LA VELOCIDAD DE GIRO DEL MOTOR (3) DE ACUERDO CON UN VALOR NORMAL CUANDO LA RELACION RELATIVA CALCULADA ES MENOR QUE UN VALOR PREFIJADO, FIJANDOLA BAJA CUANDO ES MAYOR QUE EL VALOR PREFIJADO. POR ELLO, UNA LENTE (1) SE MUEVE A BAJA VELOCIDAD CUANDO LA LENTE DE ENFOQUE ESTA CERCA DE LA POSICION DE ENFOQUE Y A ALTA VELOCIDAD CUANDO ESTA DESENFOCADA.
