摘要:
A method of operating an image sensor includes generating a plurality of ramping up/down signals, and comparing a correlated double sampled pixel signal produced from an output of a pixel with a correlated double sampled first ramping up/down signal among the plurality of ramping up/down signals in a reset interval. The method further includes comparing the correlated double sampled pixel signal with the correlated double sampled first ramping up/down signal at one sampling time or more in an image interval, and a step of outputting a selected ramping up/down signal among the plurality of ramping up/down signals based on a result of the comparison.

Provided are an apparatus and method for processing motion picture and a record medium, which decompose a motion picture into unit frames and insert copyright information into the unit frames, enabling to determine the infringement of copyright when the motion picture is illegally circulated. The apparatus includes a processing unit, a merging unit and an output unit. The processing unit decomposes a motion picture into a plurality of unit frames, and generates a main frame, a sub-frame including copyright information for the motion picture and a degree frame which is paired with the sub-frame, based on the unit frames. The merging unit merges the sub-frame into the main frame according to a degree of mergence of the degree frame. The output unit continuously outputs the merged frames in time order.

Disclosed herein is a method for producing monohydric alcohols from monocarboxylic acids or derivatives thereof using a catalyst comprising ruthenium (Ru) and tin (Sn) using zinc oxide (ZnO) as both a catalyst support and an active promoter; a catalyst prepared by adding an inorganic binder such as silica, alumina or titania in a limited range to the catalyst comprising the above components in order to impart a shaping ability to the catalyst; or, a modified catalyst reformed by adding at least one reducing component selected from the group consisting of Co, Ni, Cu, Ag, Rh, Pd, Re, Ir, and Pt to the catalyst in order to improve the reducing ability of the catalyst. By using such catalysts, the method according to the present invention is advantageous in that the monohydric alcohols can be prepared in high yield regardless of whether the monocarboxylic acids contain water or not, the monohydric alcohols can be economically prepared because the catalysts can be operated under mild reaction conditions and also exhibits high selectivity and productivity compared to conventional catalysts, and the catalysts have excellent long-term reaction stability so as to be advantageous for industrial applications.

Disclosed are a semiconductor devices and method of fabricating the same. Anti-etch films are formed in the top corners of the device isolation film using a material that has a different etch selectivity ratio from nitride or oxide and is not etched in an oxide gate pre-cleaning process. It is thus possible to prevent formation of a moat at the top corners of the device isolation film and the gate oxide film from being thinly formed, thereby improving reliability and electrical characteristics of the device.
