Abstract
A method and system for scaling an image in accordance with the present invention is disclosed. The method utilizes a plurality of interpolators operating in parallel. Each interpolator operates with a different spatial offset with respect to the other. The final output is the average the output of each interpolator. Normally the initial value of the horizontal and vertical DDA's is zero. Offset is introduced by introducing an initial value in the DDA. Offset has the physical effect of manipulating the weights required for the averaging process in interpolation. Horizontal offset is the initial value in the Horizontal DDA while the vertical offset is the initial value in the Vertical DDA. The present invention relates to implementation in a semiconductor integrated circuit but the concepts can be used in software based image resizing (scaling) algorithms too.
