Abstract
Provided are an apparatus and method for adjusting focus using the MTF characteristics of a lens in a digital image processing apparatus that adjusts focus using optical characteristics of a lens. The apparatus for adjusting focus includes: an image pickup unit in which modulation transfer function (MTF) data, which can be used to represent the performance of a lens, is stored; and a digital signal processing unit that calculates a focus peak value of an image and a defocus correction value based on the MTF data, and corrects the focus position using the focus peak value and the defocus correction value.
