Abstract
The present invention discloses a face tracking method for electronic camera devices. The method is applied to an electronic camera device having a face database and a face classifier, and the face database is provided for storing data such as a position, a size and a skin color prototype of a face in a previously stored preview image, and the method includes the steps of: obtaining a current preview image; determining whether or not a known face exists in the face database; defining a searching space on the current preview image; and using the face classifier to detect the searching space in the current preview image, and determining whether or not a face exists in the searching space.
