Abstract

UN APARATO DE PROCESAMIENTO DE IMAGENES QUE TIENE UNA FUNCION PARA GIRAR LOS DATOS DE IMAGEN ALMACENADOS EN UNA MEMORIA 90 (GRADOS) MIENTRAS EVITA EL DETERIORO DE LA CALIDAD DE LA IMAGEN. AL LEER LA IMAGEN, SI LA DENSIDAD DE LINEA EN UNA DIRECCION DE SUBEXPLORACION ES INFERIOR A LA DENSIDAD DE PIXELS EN UNA DIRECCION PRINCIPAL DE EXPLORACION, LA DENSIDAD DE LINEAS SE ELEVA CERCA DE LA DENSIDAD DE PIXELS. EL CONTROL DE LECTURA SE REALIZA DE ACUERDO CON LA POSIBILIDAD DE ROTACION DE 90 (GRADOS) DE LA IMAGEN EN UN APARATO DE DESTINO O UN TAMAÑO ESPECIFICO DE UNA IMAGEN ORIGINAL. ESTO CONSIGUE UN USO EFICIENTE DE LA MEMORIA DE IMAGEN.
