Claim One:
1. A method of tracking a face in a reference image stream using a digital image acquisition device, comprising: a. acquiring a full resolution main image and an image stream of relatively low resolution reference images each including one or more face regions; b. identifying one or more face regions within two or more of said reference images; c. determining a relative movement between said two or more reference images; d. determining a size and location of said one or more face regions within each of said two or more reference images; e. applying concentrated face detection to at least a portion of said full resolution main image in a predicted location for candidate face regions having a predicted size as a function of the determined relative movement and the size and location of said one or more face regions within said reference images, to provide a set of candidate face regions for said main image; f. applying image processing to said main image based on said information regarding said set of candidate face regions to generate a processed version of the main image; and g. displaying, storing, or transmitting the processed version of said main image, or combinations thereof.
