Claim 9:
10. The image processing apparatus of claim 8, wherein
the processor is configured to:
for a set high frequency band in the third decomposed sub-band information, determine the frequency band coefficient matrix of the set high frequency band in the second decomposed sub-band information as the frequency band coefficient matrix of a corresponding set high frequency band in the third decomposed sub-band information;
for each frequency band in the third decomposed sub-band information except the set high frequency band, determine a coefficient value corresponding to each pixel point in the frequency band coefficient matrix of each frequency band in the third decomposed sub-band information, as an average value of a coefficient value of the corresponding pixel point in the frequency band coefficient matrix of the corresponding frequency band in the first decomposed sub-band information and a coefficient value of the corresponding pixel point in the frequency band coefficient matrix of the corresponding frequency band in the second decomposed sub-band information.
