Abstract
Un sistema de imagen de enfoque autom?tico que incluye un sensor de imagen onde el sensor es acoplado a un controlador. El sensor de imagen capta una imagen que tiene al menos un borde con una anchura. El controlador genera una se?al de enfoque que es una funci?n de la anchura del borde. Un lente recibe la se?al de enfoque y ajuste el enfoque. La anchura de borde se puede determinar mediante diversas t?cnicas como el uso de gradientes. Un histograma de las anchuras de borde se puede utilizar para determinar si una determinada imagen est? enfocada o desenfocada. Un histograma con una gran poblaci?n de finas anchuras de borde es indicativo de una imagen enfocada.
