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.
Claims10
An interpolation method for digital pictures, comprising the steps of:
- dividing a blank region among pixels equally into a plurality of squares;
- determining an interpolation parameter for each of the squares relative to its sampling point according to the position of the square;
- compressing and storing the interpolation parameters of all the squares relative to their sampling points;
- zooming the picture and making sure that the inerpolating point falls into a target square;
- de-compressing the interpolation parameters according to the position of the target square and computing the interpolation parameter corresponding to the square;
- and
- using the interpolation parameters and the brightness of the sampling points to compute the brightness of the interpolating point.
