Abstract
ES ASUNTO DE LA INVENCION MINIMIZAR UN DETERIORO DE IMAGEN DEBIDO A UNA CONVERSION DE IMAGEN. PARA TAL UN OBJETO, ENTRE PARAMETROS QUE TIENEN EN CUENTA UNA CALIDAD DE IMAGEN DE UN APARATO FACSIMIL DE COLOR EN EL LADO DE TRANSMISION, SE CODIFICA LA INFORMACION DE IMAGEN EN COLOR DE ACUERDO CON UN PARAMETRO QUE OPTIMIZA LA CALIDAD DE IMAGEN Y LA ALMACENA. SE RECONOCE UN PARAMETRO QUE TIENE EN CUENTA LA CALIDAD DE IMAGEN DE LA INFORMACION DE IMAGEN EN COLOR QUE TIENE UN APARATO FACSIMIL DE COLOR EN EL LADO DE RECEPCION Y SE COMPARA CON EL PARAMETRO DEL APARATO FACSIMIL DE COLOR EN EL LADO DE TRANSMISION. DE ACUERDO CON EL RESULTADO DE LA COMPARACION, SE EJECUTA UNA CONVERSION DE IMAGEN DE LA INFORMACION DE IMAGEN DE COLOR ALMACENADA.
