    • An autofocus method includes acquiring an image of a scene that includes one or more out of focus faces and/or partial faces. The method includes detecting one or more of the out of focus faces and/or partial faces within the digital image by applying one or more sets of classifiers trained on faces that are out of focus. One or more sizes of the one of more respective out of focus faces and/or partial faces is/are determined within the digital image. One or more respective depths is/are determined to the one or more out of focus faces and/or partial faces based on the one or more sizes of the one of more faces and/or partial faces within the digital image. One or more respective focus positions of the lens is/are adjusted to focus approximately at the determined one or more respective depths.
    • 自动聚焦方法包括获取包括一个或多个聚焦面和/或部分面的场景的图像。 该方法包括通过应用在不在焦点的面上训练的一组或多组分类器来检测数字图像内的焦点外面部和/或部分面部中的一个或多个。 在数字图像内确定更多相应的失焦面和/或部分面中的一个的一个或多个尺寸。 基于数字图像中的多个面和/或部分面之一的一个或多个尺寸,对一个或多个失焦面和/或部分面确定一个或多个相应的深度。 调整透镜的一个或多个相应的焦点位置以大致聚焦在所确定的一个或多个相应的深度处。
