Abstract

본 발명은 별도의 특수촬영등에 의한 입체영상(3D)을 구현함이 없이 일반비디오신호(2D)를 신호적인 처리를 통하여 입체영상(3D)으로 변환시키는 장치에 관한 것이다. 즉, 입력되는 일반영상 신호(2D)를 동기분리하여 기수피일드(Q)와 우수피일드(Q~)로 분리한후, 각각의 동기신호를 지연, 증폭처리하여 정상적인 영상신호와 지연된신호가 중첩되어 나타나므로써, 화면속에서는 사물이 거리의 길이와 원근감이 있는 것처럼 보이도록한, 인간의 잔상효과를 최대한 활용한 일반영상(2D)를 입체영상신호(3D)로 변환하는 장치이다.The present invention relates to an apparatus for converting a general video signal (2D) to a stereoscopic image (3D) through a signal processing without implementing a stereoscopic image (3D) by a separate special shooting. That is, the normal video signal (2D) input is separated synchronously and separated into odd-numbered (Q) and even-numbered (Q ~) signals, and then the delayed and amplified signals are delayed and amplified. By overlapping, it is a device that converts a general image (2D) that takes full advantage of the afterimage effect of a human being to a stereoscopic image signal (3D) in which objects appear to have a distance and a perspective.
