Document Type and Number:
Japanese Patent JP2003299098
Kind Code:
A
Abstract:
To decode high-quality image data by constituting an apparatus with less memories.
In a seed data correcting section 18, seed data are corrected with the seed weight data of a weight to be added to the seed data to be origin for generating a conversion coefficient used for converting a DCT (discreet cosine transform) into a pixel value, and in a conversion coefficient generating section 14, the conversion coefficient is generated from the corrected seed data. A product-sum operation section 15 performs a product-sum operation by using the DCT coefficient and a conversion coefficient to convert the DCT coefficient into the pixel value.
