Abstract
Un dispositivo que analiza una imagen. El dispositivo incluye un circuito que recibe ?magen que incluye una pluralidad de pixeles. El circuito crea un histograma de la y analiza el histograma para determinar una exposici?n aceptable de la imagen. El histograma puede incluir una pluralidad de binarios versus una poblaci?n de pixeles asociada cada binario. De manera de ejemplo, los binarios pueden estar asociados con una intensidad de luz. Las im?genes e histogramas pueden incluir datos definidos por n?mero de din?mico bajo de bits y/o un numero de rango din?mico extendido de bits. Ciertas caracter?sticas y criterios de la imagen pueden determinarse y analizarse para determinar si imagen tiene una exposici?n aceptable. Si la imagen es inaceptable, una caracter?stica de exposici?n puede ser cambiada y el proceso puede ser repetido hasta que una imagen aceptable sea obtenida.
