Patent ID: 8175121

Claim:
An image display apparatus, comprising: a first motion vector acquisition section for acquiring and outputting an image motion vector in pixel or a predetermined block unit from plural frames included in an input image signal; a second motion vector acquisition section including an edge filtering section for filtering a predetermined edge component from the input image signal, and acquiring a motion vector for the specific area by utilizing the predetermined edge component filtered by the edge filtering section; a frame interpolation section for generating an interpolated frame by using the motion vector provided by the second motion vector acquisition section and for combining the interpolated frame with a frame of the input image signal, thereby composing a signal of a new frame sequence; and a display section for displaying an image based on the frame sequence outputted from the frame interpolation section, wherein the first motion vector acquisition section gives a different motion vector to areas other than a specific area of a frame in the input image signal; and wherein the frame interpolation unit shifts the two frames in a horizontal and/or vertical direction in a predetermined pixel unit and detects the number of times or frequency the predetermined edge components coincide with each other between the two frames to compose a histogram, and designates a shift quantity having a greatest number of the edge component coincidences on the histogram as a motion vector for the specific area.
