Claim 11:
12. The image processing apparatus of claim 8, wherein
the processor is configured to:
determine the frequency band coefficient matrix of the third decomposed sub-band information in each frequency band, as a sum of a third matrix and a fourth matrix, in which the third matrix is a product of a corresponding weighting coefficient with the frequency band coefficient matrix of the first decomposed sub-band information on the corresponding frequency band, and the fourth matrix is a product of a corresponding weighting coefficient with the frequency band coefficient matrix of the second decomposed sub-band information on the corresponding frequency band;
wherein a sum of the corresponding weighting coefficients of the first decomposed sub-band information and the second decomposed sub-band information on the same frequency band is 1; and the corresponding weighting coefficient of the second decomposed sub-band information on a frequency band is negatively correlated to a number of decomposition levels to which the frequency band belongs.
