摘要
A method for converting an interlaced scan image, having a plurality of pixels arranged in a matrix of rows and columns, to a progressive scan image processes interpolated picture elements (pixels) at target pixel positions between two successive rows of the interlaced scan image. The method determines if a pixel on a current row is an edge pixel and if the pixel is an edge pixel, it determines an approximate angle for the edge based on a difference between the column number of at least the edge pixels on the current row and the column number of at least one edge pixel on a previous row. The method uses the angle to determine which pixel on the current row and previous row correspond to the target pixel and interpolates the value of the target pixel from the corresponding pixels.
