A photographing apparatus capable of automatic detection of a focus of a subject and a method thereof are disclosed. The photographing apparatus includes a control unit for detecting the focus of the subject using images of the subject acquired with a moveable lens being in different positions so as to allow the detection of the focus of the subject automatically and nearly simultaneously with the photographing the subject without using a separate AF module that requires light separation and/or separate dedicated focus image sensor.

An image stabilizer includes a rotor including a lens assembly, and configured to move perpendicular to an optical axis of light passing through the lens assembly, and a suspension unit configured to support movement of the rotor and to prevent the rotor from moving non-perpendicular to the optical axis of the light passing through the lens assembly. Accordingly, the image stabilizer prevents variance of characteristics of a rotor in a low frequency band according to the position and distortion of phase characteristics in a high frequency band. Therefore, the image stabilizer has consistent operation characteristics regardless of the position, posture, and movement of a person using an image capture device containing the image stabilizer.

A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelength. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.
