Abstract
A transforming and/or inverse transforming system, medium, and method for a multi-codec. The transforming system includes a first matrix storage storing 1-dimensional DCT (discrete cosine transform) matrixes corresponding to respective transformation techniques, a second matrix storage storing 2-dimensional DCT matrixes corresponding to the respective transformation techniques, a 1-dimensional transformer 1-dimensionally transforming an input image using a 1-dimensional DCT matrix corresponding to a set transformation technique, a 2-dimensional transformer 2-dimensionally transforming the 1-dimensionally transformed image using a 2-dimensional DCT matrix corresponding to a set transformation technique, and an enhancement transformer enhancement transforming the 1-dimensionally transformed image to improve efficiency of integer transformation.
