ABSTRACT:
An image scaling circuit and a method for scaling an image into images with different ratios are provided. The image scaling circuit includes a line buffer memory apparatus, a line buffer control apparatus, a first and a second scaling circuit. The first scaling circuit is coupled to the line buffer memory apparatus, and performs a first image scaling interpolation operation on the data output by the line buffer memory apparatus. The second scaling circuit is coupled to the line buffer memory apparatus, and performs a second image scaling interpolation operation on the data output by the line buffer memory apparatus. The line buffer control apparatus is coupled to the line buffer memory apparatus, the first scaling circuit and the second scaling circuit, for controlling the line buffer memory apparatus to receive or output a scan line data according to the operation status of the first and second scaling circuits.
