The method includes: a metal nucleus adsorbing step of introducing a vapor phase metal compound into a process space where the glass substrate having the amorphous silicon formed thereon is disposed, to adsorb a metal nucleus contained in the metal compound into the amorphous silicon layer; a metal nucleus distribution region-forming step of forming a community region including a plurality of silicon particles every metal nucleus in a plane boundary region occupied by the metal compound by a self-limited mechanism due to the adsorption of the metal nucleus; and an excess gas removing step of purging and removing an excess gas which is not adsorbed in the metal nucleus distribution region-forming step.
Abstract:
Disclosed is a composition containing phosphatidylserine as an effective ingredient, and more particularly to a composition containing phosphatidylserine as an effective ingredient for protecting and improving a skin, reinforcing a skin barrier function, suppressing and alleviating an inflammatory response, treating and improving an atopic skin, activating PPAR-a promoting a differentiation of the skin, protecting the skin and preventing and improving skin aging and wrinkle. Accordingly, it is possible to protect and improve the skin from the injury due to the ultraviolet or the external stimulating material such as chemical material and to reinforce and strengthen the skin barrier function using the composition, thereby improving a general skin state.
Abstract:
A liquid zoom lens mounted on a portable terminal is provided. In the liquid zoom lens, a cylindrical body has upper and lower openings to which one pair of lenses is coupled. An auto-focus lens part includes a first insulating liquid layer, a first electrolyte layer, and a first lens. The first insulating layer and the first electrolyte layer are disposed to form an interface at a lower portion of the body. The first lens is disposed on the first electrolyte layer and has a periphery closely attached to a lower portion of an inner periphery of the body. An optical zoom lens part includes a second insulating liquid layer, a second electrolyte layer, and a second lens. The second insulating liquid layer and the second electrolyte layer are disposed to form an interface on the first lens. The second lens is fixed to be movable within the second insulating liquid layer, such that a periphery is closely attached to the inner periphery of the body. Accordingly, the auto-focus function and the optical zoom function can be simultaneously achieved through a single liquid lens whose curvature is varied by the difference of the inherent refractive index between the electrolyte and the insulating liquid.

A deinterlacing apparatus and method thereof include a motion compensation unit implementing motion-compensated temporal interpolation for each of estimated motion vectors with reference to a previous field and a next field, which are respectively ahead of and behind a current field to be interpolated, producing interpolation values of a pixel to be interpolated, and outputting a selected value from the interpolation values as a first interpolation value. Further, a spatial interpolation unit producing a second interpolation value of the pixel to be interpolated using values of pixels around the pixel to be interpolated, and an output unit mixing the first and second interpolation.

An image size conversion apparatus and an image size conversion method are provided. The image size conversion apparatus includes an area detector which detects an interested area having a certain image distinguished over a general image from an input image, a scale ratio adjustor which adjusts a scale ratio for the interested area detected by the area detector, and a scaler to perform scaling for the input image according to the adjusted scale ratio. Accordingly, the scale ratio can be adjusted according to features of the input image so that an image without distortion can be displayed on a screen.

An apparatus for converting an image signal includes a motion estimation unit which estimates a motion vector using current and reference fields; a ticker region detection unit which detects a ticker region of an image using the estimated motion vector where an image moving with a constant speed and direction in a current field is found; a motion information analysis unit which determines whether or not there exists an image moving with a constant speed and direction in the ticker region based on the frequency of a motion vector estimated within the detected ticker region; and an interpolation unit which interpolates the current field by controlling a degree of temporal and spatial interpolations using an output of the motion information analysis unit. Accordingly, interpolation is differently applied in accordance with characters and graphics moving with a constant speed and direction in an input image, so that picture quality can be enhanced.
