Claim 2:
3. The image processing method of claim 1, wherein
determining the third decomposed sub-band information according to the first decomposed sub-band information and the second decomposed sub-band information comprises:
for a set high frequency band in the third decomposed sub-band information, determining 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, determining 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.
