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.

Provided are an apparatus and method for forensic marking of digital content. The apparatus includes a forensic marker configured to generate first content by inserting a first binary forensic mark in original content and second content by inserting a second binary forensic mark in the original content, and when a content service request is generated, combine the first content and the second content on the basis of information about a user who has requested the content service and thereby generate third content in which a forensic mark corresponding to the user information is inserted, a content database configured to store the first and second content, and a transceiver configured to transmit the third content.
摘要:
A music playing system using a music visualization technique includes: a music information extraction unit for extracting one or more pieces of music information regarding basic characteristics, meta-characteristics and emotional characteristics of music, the music including music being played at present, music selected for playing, and music selected for visualization; and a display control unit that provides a user interface window for visualizing the extracted music information and controls the user interface window, wherein the user interface window includes a visualization configuration panel having a setup function for selecting the music information to be extracted.
摘要:
Disclosed are a forensic marking method and a forensic marking system capable of inserting in real-time a forensic mark for user information in digital contents provided online. The forensic marking method of the digital content according to an exemplary embodiment of the present disclosure includes generating a first content created by inserting a first forensic mark in an original content and a second content created by inserting a second forensic mark in the original content by a content server; transmitting the first and second contents to a client terminal by the content server; and combining fragments of the first and second contents in a combination order corresponding to user information to generate a third content by the client terminal
摘要:
A forensic mark insertion apparatus includes: an original content segment storage unit for storing multiple original contents; and a service control unit for, in response to a request for a content from a user, retrieving an original content corresponding to the request for the content from the original content segment storage unit, separating the retrieved original content into plurality of content segments, selectively inserting a forensic mark into some of the content segments, and assembling the content segments to produce an forensic-mark inserted content to be provided to the user.

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.
