In this paper, we describe our development of Frame Rate Conversion (FRC) technology that provides picture quality improvement for LCD by doubling its frame rate. Based on an analysis of motion speed of real broadcasting video, we point out that the “character telop” is a special type of input signal that is considered to be able to obtain a significant picture quality improvement by using double‐frame rate LCD‐TV. Then, an FRC technology that has a feature of improving a picture quality of “character telop” in particular, as well as a LSI implementing FRC is introduced. We also verified that the FRC was effective by actually measuring the effect using TV sets equipped with the FRC‐LSI.
