Encoding/decoding device, encoding/decoding method and storage medium

摘要

This is an encoding device for compressing/encoding an input video signal. The encoding device comprises a reduction/conversion unit(44) for converting the format of either a luminance component or a chrominance component according to the characteristic of the input video signal and an encoding unit for compressing/encoding the video signal whose format is converted by the reduction/conversion unit(44) to generate encoded data.
