Abstract:
1. An image processing apparatus comprising: a random processing device configured to add independent random components to a pixel value of a pixel point on each actual frame corresponding to a given first time and a pixel value of a pixel point on each actual frame corresponding to a second time subsequent to the first time respectively to obtain random-processed pixel values, wherein the added independent random components have at least two degrees of freedom; and a weighting/adding device configured to weight the random-processed pixel values to obtain a pixel value of a pixel point on at least one interpolation frame corresponding to an intermediate time between the first time and the second time, wherein a pixel value rk (where k=1, 2, 3, . . . , K) of each interpolation pixel point is determined from the following equation: where p(t 1 ) is a pixel value of pixel point corresponding to interpolation pixel point at actual frame immediately before interpolation frame, p(t 2 ) is a pixel value of pixel point corresponding to interpolation pixel point at actual frame immediately after interpolation frame, rand(i) is a function that returns pseudorandom numbers based on a value of i, rand(i) % Sw is a function that returns the surplus obtained by dividing rand(i) by Sw, Sw is a designated value of random strength, and wi is a weighting/adding weight.
