Abstract
In an image display device having a frame rate converting (FRC) portion, it is possible to prevent image degradation of a combined image display portion such as an OSD and PinP attributed to the FRC process. The image display device includes: an FRC portionfor converting the number of frames of an input image signal by interpolating an image signal subjected to a motion compensation process between the frames of the input image signal; an OSD processing portionfor superposing an OSD signal on the input image signal, and a controlling portion. The FRC portionhas a motion vector detecting portionfor detecting a motion vector between the frames of the input image signal, an interpolation vector evaluating portionfor allocating interpolation vector between frames based on the motion vector information, and an interpolation frame generating portionfor generating an interpolation frame from the interpolation vector. When the OSD signal is superposed on the input image signal, the controlling portiondisables the motion compensation process of the FRC portionby making the motion vector detected by the motion vector detecting portion0 vector.
