20120106937METHOD FOR FOCUSING - A camera and a method for selecting a focus region in a camera view have a plurality of focus regions that are defined in the camera view. A focus distance of the camera is repeatedly set to focus at different distances by setting a lens distance of the camera to different lens distance values. A focus value is determined for each focus region at the set lens distance value. A function for a plurality of focus regions is estimated based on a plurality of determined focus value and lens distance value pairs. A local maximum point of the function is calculated for each focus region for which a function has been estimated, where the local maximum point has a lens distance value. Focus regions are grouped, rated and selected based on the lens distance value of the local maximum point of the focus regions and spatial distances between the focus regions.05-03-2012
