Patent ID: 8768103

Claim:
A video conversion apparatus for receiving an input video signal including a plurality of frames, generating interpolation frames in accordance with the frames of the input video signal, and converting into a video signal including a part of frame of the plurality of frames included in the input video signal and the interpolation frame, comprising: a motion vector detection unit for detecting a motion vector among the plurality of frames included in the input video signal; an image feature detection unit for detecting a feature of a video by generating histogram information concerned with the motion vector detected in the motion vector detection unit; and a series of interpolation frame generation unit for carrying out: a first interpolation frame generation processing for generating an interpolation frame using the motion vector detected by the motion vector detection unit and the plurality of frames included in the input video signal, a second interpolation frame generation processing for rendering one of frame in the plurality of frames included in the input video signal into an interpolation frame intact, and a third interpolation frame generation processing for rendering a linear interpolation frame of two frames among the plurality of frames included in the input video signal as an interpolation frame to generate the interpolation frame, to generate a series of interpolation frame including a part of frame of the plurality of frames included in the input video signal and the interpolation frame generated from the first to third interpolation frame generation processing; wherein the series of interpolation frame generation unit, in accordance with a judgment result judged by the image feature detection unit, switching among: a first operation for generating a series of frames including the interpolation frame generated in the first interpolation frame generation processing and a part of frame of the plurality of frames included in the input video signal, a second operation for generating a series of frames including the interpolation frame generated in the second interpolation frame generation processing and a part of frame of the plurality of frames included in the input video signal, and a third operation for generating a series of frames including the interpolation frame generated in the first interpolation frame generation processing and a part of frame of the plurality of frames included in the input video signal and the interpolation frame generated in the third interpolation frame generating processing, and in the series of frames generated by the third operation, the interpolation frame generated in the first interpolation frame generating processing is inserted between the frame included in the input video signal and the interpolation frame generated in the third interpolation frame generating processing.
