Patent ID: 8525923

Claim:
A focusing apparatus comprising: a focus lens; a focus lens driving unit for moving the focus lens in an optical axial direction; an imaging device for generating an image signal by transforming light of an image of a subject, which is incident on the focus lens, into an electrical signal; a focus evaluation value obtaining unit for obtaining a first focus evaluation value according to a location of the focus lens by automatically moving the focus lens, and obtaining a second focus evaluation value according to a location of the focus lens by manually moving the focus lens, in relation to the image signal; a peak value obtaining unit for obtaining a peak value of the first focus evaluation value; a focus lens location obtaining unit for detecting a location of the focus lens corresponding to the peak value; an information generation unit for generating focus evaluation value information corresponding to the second focus evaluation value; and a providing unit for providing the focus evaluation value information, wherein the second focus evaluation value is obtained from an image signal of a focus region in which the peak value is obtained.
