Abstract
LA INVENCION SE REFIERE A UN CODIFICADOR DE IMAGENES (1) QUE ESTA EQUIPADO CON UN CONTROLADOR DE CODIFICACION (112A) QUE PRODUCE UN PARAMETRO DE CODIFICACION DE LA TRANSMITANCIA (121), PARA CONTROLAR EL PROCESAMIENTO DE CODIFICACION DE UNA SEÑAL DE TRANSMITANCIA, BASANDOSE EN UN PARAMETRO DE CODIFICACION DE LOS VALORES DEL ELEMENTO DE LA IMAGEN (104), PARA CONTROLAR EL PROCESAMIENTO DE CODIFICACION DE UNA SEÑAL DEL VALOR DE UN ELEMENTO DE LA IMAGEN, Y PARA CODIFICAR-PROCESAR LA SEÑAL DE TRANSMITANCIA (102), BASANDOSE EN EL PARAMETRO DE CODIFICACION DE LA TRANSMITANCIA (121), TAL COMO SE MUESTRA EN LA FIGURA. EN DICHA CONSTITUCION DEL CODIFICADOR DE IMAGENES (1), ES POSIBLE CONTROLAR LA CALIDAD DE UNA IMAGEN OBTENIDA A PARTIR DE LA SEÑAL DE TRANSMITANCIA DE CADA IMAGEN, DE ACUERDO CON LA CALIDAD DE UNA IMAGEN OBTENIDA A PARTIR DE LA SEÑAL DEL VALOR DEL ELEMENTO DE LA IMAGEN, DE CADA IMAGEN EN UN IMAGEN COMPUESTA, MEDIANTE LO CUAL SE PUEDE ACORTAR LA INFORMACION REDUNDANTE DE UNA SEÑAL CODIFICADA DE TRANSMITANCIA (106) OBTENIDA MEDIANTE LA CODIFICACION DE ESA SEÑAL DE TRANSMITANCIA, SIN DAÑAR LA CALIDAD DE IMAGEN DE LAS IMAGENES INDIVIDUALES, CONSECUENTEMENTE LA SEÑAL DE LA IMAGEN SE PUEDE GRABAR, Y SE PUEDE TRANSMITIR, SIN DISMINUIR LA CALIDAD DE LA IMAGEN, CON MENOS BITS.
