The standard information recording medium 1 reduces the number of pixels of image information to be encoded as in the format shown in FIG. 4, the image is composed of several blocks, orthogonally transformed for each block, quantized and compressed. The image is encoded and recorded on the medium. As for a signal having a strong correlation as a means for compressing information, when viewed on the frequency axis, signal power is concentratedly distributed to a specific frequency component. If only the coefficients of the components distributed by concentrating the signal power are encoded, the total amount of information can be reduced. Known as the transform to the frequency domain is the Fourier transform, which involves complex arithmetic
Since the configuration becomes complicated, an orthogonal transform instead of this is used in image coding.
