Abstract
An imaging system is provided that includes an area determiner and readout processor. The area determiner defines an area used in an auto focus operation within an effective pixel area of an image sensor. The readout processor reads out only pixel signals within the defined area. The size of the area is determined according to at least one of a focal length or a magnitude of camera shake.
