Abstract:
1. A method for converting initial digital video data having a format including an input sequence of pixels extending in a first direction at a first spacing into output digital video data having a format including an output sequence of pixels extending in said first direction at a second spacing, different from said first spacing, wherein said method comprises: transforming coordinate values of a first sequence of pixels within said input sequence of pixels into a first transformation function by applying a decorrelating transform to said coordinate values of said first sequence of pixels, wherein applying said decorrelating transform to said coordinate values of said first sequence of pixels removes a statistical correlation between coordinate values of sequentially adjacent pixels within said first sequence of pixels; and determining coordinate values for generating a second sequence of pixels forming a portion of said output sequence of pixels by evaluating, at locations of pixels sequentially adjacent in said first direction at said second spacing, a function formed by applying an inverse of said decorrelating transform to said first transformation function.
