【発明の名称】混合モード空間および時間近似技法を使用するビデオ信号を逆インタレースする方法
Document Type and Number:
Japanese Patent JP2003514406
Kind Code:
A
Abstract:
A method of de-interlacing interlaced video formats using a mixed mode spatial and temporal approximation technique. This method can be implemented with input of known pixel values obtained from only two fields, featuring the current spatial field containing missing pixels, and either of two neighbor temporal fields containing known pixels. Decision steps requiring evaluation of a series of logical operations lead to assignment of values to missing spatial pixels. There is a feedback step of approximated values of missing pixels from one cycle to the next cycle of approximation of missing pixel values. This method is applicable to a variety of video interlaced signals, including interlaced RGB component signals, and video signals containing luminance and chrominance components. Video de-interlacing according to the present invention is an efficient way of having image processing devices operating with interlaced technology be compatible with visual display monitors operating with de-interlaced (progressive) high resolution scan format systems. Moreover, the method of this invention is applicable to real time and off-line modes of operation of video and television systems currently using interlaced scanning formats.
