Patent ID: 8384826

Claim:
An image displaying device having a rate converting portion that interpolates an interpolation image signal between frames or fields of an input image signal to convert the number of frames or fields of the input image signal, further comprising a determining portion that determines the degree of deterioration of the input image signal, wherein the rate converting portion comprises an interpolation image generating portion that generates the interpolation image signal by applying a motion compensation processing to the input image signal based on the motion vector information between frames or fields of the input image signal, and when the degree of the deterioration of the input image signal determined by the determining portion is equal to or higher than a predetermined value, the interpolation of the image signal generated by applying the motion compensation processing is not executed, wherein when the degree of the deterioration of the input image signal determined by the determining portion is equal to or higher than a predetermined value, the rate converting portion interpolates the image signal generated by making the motion compensation processing in the interpolation image generating portion ineffective between the frames or fields of the input image signal.
