Abstract
Offered digital zoom levels may be distributed at equal spacing of zoom factors. Offered digital zoom levels may be distributed among optically uniform digital zoom levels. Gradual zoom may be achieved by generating preview images at one or more intermediate digital zoom levels at which generation of a recordable image is not permitted. One or more intermediate digital zoom levels may be distributed generally evenly between two adjacent offered digital zoom levels. An image sensor supports a discrete set of zoom factors. One or more intermediate zoom factors may be distributed generally evenly between zoom factors that correspond to two adjacent offered digital zoom levels.
