Abstract (en)

[origin: WO9956247A1] In an image interpolation method, interpolated pixels are inserted (51) along horizontal and vertical directions so as to obtain a grid (I2) in which interpolated lines cross themselves in original pixels. In a second step, pixels are interpolated (52) between rows and columns formed by the grid (I2) so as to fill squares delimited by the grid (I2) to obtain an interpolated image (I3).
