Document Type and Number:
Japanese Patent JP3071205
Kind Code:
B2
Abstract:
The image data coding apparatus has an image pickup system for generating at least dynamic images. The apparatus further comprises a data processing section, two transforming sections, a quantizing section, and a coding section. The data processing section three-dimensionally arranges image data for several adjoining frames among the dynamic image data as three-dimensional image data, divides the three-dimensional image data into several three-dimensional blocks with a specified size, and outputs each three-dimensional block data. The first transforming section applies three-dimensional orthogonal transform to the three-dimensional block data and outputs three-dimensional transform coefficient data. The second transforming section transforms the three-dimensional transform coefficient data into one-dimensionally-arranged transform coefficient data. The quantizing section quantizes the one-dimensionally-arranged transform coefficient data with a specified quantization width and generates quantization output. The coding section codes the quantization output and generates coding output.
