Abstract

Se proporcionan técnicas para determinar una posición focal óptima utilizando estadísticas de enfoque automático. En una modalidad, tales técnicas pueden incluir generar puntuaciones de enfoque automático y ordinario para determinar una longitud focal óptima en la cual posicionar un lente 88 asociado con el sensor de imagen 90. Por ejemplo, la lógica de estadísticas 680 puede determinar una posición ordinaria que indica un área de enfoque óptima que, en una modalidad, se puede determinar al buscar la primera posición ordinaria en la que una puntuación de enfoque automático ordinaria disminuye con respecto a una puntuación de enfoque automático ordinaria en una posición previa. Al utilizar esta posición como un punto de inicio para la búsqueda de puntuación fina, la posición focal óptima se puede determinar al buscar un pico en puntuaciones finas de enfoque automático. En otra modalidad, las estadísticas de enfoque automático también se pueden determinar con base en cada color del Bayer RGB, de tal forma que, aun en la presencia de aberraciones cromáticas, se pueden utilizar las puntuaciones relativas de enfoque automático por cada color para determinar la dirección de enfoque. cromáticas, se pueden utilizar las puntuaciones relativas de enfoque automático por cada color para determinar la dirección de enfoque.
