Abstract:
A digital camera and method or algorithm that quickly determines if there are objects in a focus region of the camera that are nearer to or farther from the current focus position. Multiple focusing zones are used along with a technique that compares data from each of the focusing zones to determine distance relationships between objects in different zones.
