Abstract

EN UN PROCESO CONOCIDO PARA EXTENDER LA DELIMITACION ESPACIAL DE IMAGENES , EL ALARGAMIENTO DE LA DESVIACION ESPACIAL O VERTICAL SE COMBINA CON EL ALARGAMIENTO DIGITAL PURO DE LA SEÑAL EN LA DIRECCION HORIZONTAL. PARA REDUCIR LA DELIMITACION ESPACIAL DE LAS IMAGENES, A) LOS DATOS SE REGISTRAN EN UN MEDIO DE ALMACENAMIENTO ANTES DE LA EXPANSION. LOS DATOS DE IMAGEN SE EXTIENDEN DURANTE LA LECTURA; B) LOS DATOS SE EXTIENDEN SEGUN SE VAN REGISTRANDO EN EL ALMACEN DE IMAGENES. LOS DATOS SE REPRODUCEN POR LECTURA PARCIAL.
