Imaging parameters such as focus strongly influence data quality and the performance of content extraction techniques. Narrow depth of field gives clear focus but only over a short range of depths. This paper shows results from an algorithm that uses computer-controlled focus and pan camera movement in order to obtain a scene image that is a composite which is in focus at every point. The goal is to explore the possible algorithms for using both intrinsic (focus) and extrinsic (pan and tilt) camera movements to generate an image sequence and then efficiently obtain a fused composite.
