摘要

FIELD: information technology. ^ SUBSTANCE: disclosed is a coding device designed for hierarchical (multilevel) coding of upper field data and lower field data separated from each other by a set of image data representing a moving image. Said device comprises: a first coding module (12) which is configured to code one field data from two field data making up the upper field data and lower field data separate from image data, a conversion module (13) which is configured to interpolate first data of the predicted image, generated by the first coding module which codes said one of the field data, and generate second data of the predicted image in the position for scanning other field data from two field data, and a second coding module (14) which is configured to code other field data from two field data based on second data of the predicted image generated by the conversion module. ^ EFFECT: efficient hierarchical coding with separation on the level or multilevel coded data, which enables to process image data with interleaving in each level. ^ 15 cl, 18 dwg
