摘要: In an image coding apparatus, signal constituted of R, G, B components is coded in a high efficiency. The apparatus arranged by: block making means for subdividing the to make predetermined number blocks; maximum/minimum value detecting maximum and minimum each plural which constitute component signals pixels within dynamic range calculating equal difference between components; thereof from respective quantizing step width determining used quantize based upon range; accordance with determined by means.
