Abstract
Un sistema de imagen de enfoque automático que incluye una matriz de pixeles acoplada a un generador de señal de enfoque. La matriz de píxeles captura una imagen que tiene una pluralidad de bordes. El generador genera una señal de enfoque que es una función de una pluralidad de medidas de nitidez de borde, cada una estando medida a partir de uno de la pluralidad de bordes. El generador puede decidir reducir una medida relativa en la que un borde contribuye a la señal de enfoque en base de detectar que el borde no tiene suficiente simetría de reflejo, según un criterio predefinido, en una secuencia de gradientes de un señal de imagen que se extiende a través del borde.
