Image displaying device and method, and image processing device and method

Abstract

The quality of moving picture image with a large moving amount is prevented from deterioration due to moving compensation type frame rate conversion (FRC) processing. The image display device is comprised of an FRC unit () that interpolates an image signal subjected to moving compensation processing between frames so as to convert the number of frames of the input image signal, a moving amount judging unit () that judges whether a moving amount of the input image signal between the frames is larger than a predetermined value or not, and a control unit (). The FRC unit () is provided with a moving vector detecting unit () that detects a moving vector between the frames of the input image signal, an interpolation vector evaluating unit () that allocates an interpolation vector between the frames on the basis of the moving vector information and an interpolation frame generating unit () that generates an interpolation frame from the interpolation vector. In the case where the moving amount between the frames of the input image signal is larger than the predetermined value, the control unit () sets the moving vector detected by the moving vector detecting unit () to be zero-vector, and it invalidates the moving compensation processing of the FRC unit ().
