1. A method for determining image capture settings for an electronic image capture device, comprising: capturing a set of at least two preview images of a scene at different capture times using the electronic image capture device; using a processor to analyze the set of captured preview images to determine a combined motion velocity for the scene; determining one or more image capture settings responsive to the combined motion velocity; capturing an archival image with the electronic image capture device according to the determined image capture settings; and storing the captured archival image in an image memory; wherein the process of determining the combined motion velocity for the scene includes: selecting a plurality of image regions corresponding to subsets of image pixels within the captured preview images, wherein at least one of the image regions is selecting by automatically analyzing the set of captured preview images; determining local motion velocities for each of the image regions; and combining the local motion velocities to determine the combined motion velocity.
