摘要:
A digital camera system providing an extended focus range, comprising: a program memory storing instructions to implement a method for capturing a focused digital image. The method includes: setting an optical system F/# to a first F/#; capturing an evaluation image of the scene; analyzing the evaluation image to determine whether a subject is acceptably focused; if the subject is acceptably focused setting a capture F/# to be equal to the first F/#, otherwise the optical system F/# is iteratively increased until the subject is determined to be acceptably focused, or until a maximum F/# is reached; determining a capture F/# responsive to the F/# where the subject is acceptably focused; setting the optical system to use the capture F/#; capturing an archival image of the scene using the image sensor; and storing the captured archival image in a storage memory.
