Abstract
Methods for automatic focus in a stereographic imaging device that includes two imaging sensor systems are provided. Focus searches are executed on both imaging sensor systems to determine optimal focused lens positions for each. The focus searches may be executed currently or sequentially, and may be at differing lens position granularities. Focal scores and spatial locations, i.e., the locations of focus regions, may be shared between the imaging sensor systems to coordinate the focus searches. Touchscreen coordinates may also be used to coordinate the focus searches.
