Patent abstract
An interpolation method for processing digital pictures divides blank regions among the pixels equally into several squares. The interpolation parameter of each square corresponding to the sampling point is determined. These interpolation parameters are compressed and stored. When zooming a picture, the interpolating point is made sure to fall within a target square. The interpolation parameter is extracted according to the position of the target square. The brightness of the interpolating point is computed according to the interpolation parameter and the brightness of the sampling point.
