Provided are a digital photographing apparatus and method of performing different degrees of image processing on one or more faces in an image according to the distances of faces from the digital photographing apparatus or whether auto-focusing has been performed on the faces. Also provided are a digital photographing apparatus and method of performing different degrees of image processing which assist in preventing faces at farther distances from appearing more processed, for example, more blurred, than faces at closer distances and which assist in preventing faces that have not been auto-focused from appearing more processed, for example, more blurred, than faces that have been auto-focused.

Image processing method and apparatus and digital photographing apparatus using the same

Provided are a method and an apparatus for processing digital images, and more particularly, a method and an apparatus for face determination, wherein it is determined if a subject is a true subject based on distance information regarding a distance to the subject and face detection information. In an embodiment, the face detecting apparatus is a digital image processing apparatus and includes a digital signal processor for determining if a subject is a true subject based on distance information regarding a distance to the subject and face length information.

Method and apparatus for face determination

An automatic focusing method for a camera, including scanning in a macro mode, scanning in a normal mode, and additional scanning. In the scanning in the macro mode, a region within a first distance is scanned if the macro mode is set by a user. In the scanning in the normal mode, a region beyond the first distance is scanned if the normal mode is set by the user. In the additional scanning, the scanning in the normal mode is performed additionally if it is determined that the position of the focus lens found in the scanning in the macro mode does not have the largest focus value, and the scanning in the macro mode is performed additionally if it is determined that the position of the focus lens found in the scanning in the normal mode does not have the largest focus value.

Automatic focusing method for camera performing additional scanning

A method of driving a lens barrel includes detecting a movement detection signal that indicates an operation of the lens barrel which operates using a stepping motor; determining a limit time during which movement of a lens barrel component is detected based on the movement detection signal; detecting the movement from the movement detection signal; and changing a driving level of the stepping motor from a first driving level to a second driving level when movement of the lens barrel component is not detected from the movement detection signal within the limit time, wherein torque of the second driving level is greater than torque of the first driving level.

Method and apparatus for driving lens barrel, digital photographing apparatus, and computer-readable storage medium

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.

Apparatus and method for adjusting focus using modulation transfer functions

A photographing device for photographing a subject is provided. The photographing device includes a face recognition unit recognizing a face included in an image of the subject; a distance calculation unit calculating a distance between each of a plurality of faces when the plurality of faces are recognized by the face recognition unit; and a distance comparison unit comparing the distance calculated by the distance calculation unit with a pre-set reference distance. A of controlling the photographing device is also provided.
