Abstract:
1. An image processing device comprising: a supply means that supplies a coefficient data group in each sub-band, in which image data of a predetermined number of lines is decomposed for each frequency band by a hierarchical analysis filter process and which includes coefficient data of one line or more in a sub-band of at least a lowest frequency component; a synthesis filter means that synthesizes the coefficient data group supplied by the supply means in a predetermined order and generates image data in a baseband; a supply control means that controls the supply means to supply the coefficient data at such a timing that the synthesis filter means can generate the image data in the baseband at a timing corresponding to a horizontal synchronization period indicating a period between horizontal synchronization signals of the image data; and a synthesis filtering control means that controls the synthesis filter means to synthesize the coefficient data group supplied by the supply means in the predetermined order and generate the image data in the baseband at a timing corresponding to the horizontal synchronization period.
