Patent ID: 7830369

Claim:
A video signal processing apparatus, comprising: an input portion, into which n pieces of video frames (n: an integer equal or larger than 2) are inputted; and a resolution converter portion, which is configured to obtain an output video frame with increasing a number of pixels building up the video frame, by composing the n pieces of said video frames inputted, wherein said resolution converter portion comprises: a motion estimation portion, which is configured to estimate a sampling phase difference with using video data on said input video frame as a reference and each video data on other input video frame; a motion compensation/up-rate portion, which is configured to compensate motion of the video data of the each input video frame with using information of said sampling phase difference, as well as, to increase the number of pixels to n times; a phase shift portion, which is configured to shift the video data of each of said video frames, the pixel number of which is increased, by a predetermined amount; a coefficient determining portion, which is configured to determine a coefficient with using information of said sampling phase difference; and an aliasing component removal portion, which is configured to remove (n−1) pieces of aliasing components, by adding each of video data in front and back of said phase shifting after multiplying said coefficient, thereby to provide an output.
