Image displaying apparatus having frame rate conversion and method thereof

An image displaying apparatus with an FRC(Frame Rate Conversion) function and an FRC(Frame Rate Conversion) method are provided to simplify a motion estimation method and convert and output a frame rate of an input image signal, thereby reducing motion judders of a time axis direction and accordingly improving image quality. An image displaying apparatus comprises the following parts: an FRC(Frame Rate Conversion) unit(120) which converts a frame rate of an input image signal according to motion of the image and outputs the converted image; and a display unit(160) which performs signal processing of the input image signal outputted from the FRC unit, and displays the signal-processed input image signal on a screen.
