Patent ID: 8462266

Claim:
An image display device comprising: a rate converting portion configured to convert the number of frames or fields of a input image signal by interpolating an interpolation image signal generated by executing motion compensation processing for the input image signal based on motion vector information between frames or fields of the input image signal between frames or fields of an input image signal, wherein an edge enhancement portion configured to subject the input image signal to edge enhancement processing at a first edge enhancement level and said edge enhancement portion also configured to subject the interpolation image signal to the edge enhancement processing at a second edge enhancement level lower than the first edge enhancement level, the rate converting portion includes a motion vector detecting portion that detects a motion vector between consecutive frames or fields included in the input image signal, an interpolation vector allocating portion configured to receive the detected motion vector and the input image signal and configured to allocate an interpolation vector between the frames or the fields of the input image signal based on the detected motion vector, an interpolation image generating portion configured to receive the allocated interpolation vector and the input image signal and configured to generate an interpolation image signal based on the allocated interpolation vector and input image signal, and an image interpolating portion configured to receive the generated interpolation signal and configured to interpolate the generated interpolation image signal between the frames or the fields, and configured to obtain a motion amount/motion direction of the input image signal based on the motion vector detected by the motion vector detecting portion.
