Abstract
In a moving image coding apparatus, when a first picture is entropy-coded, if an occupancy of a virtual buffer is below a predetermined position, the first picture is replaced with a copy picture. Further, among succeeding pictures that refer to a reference image corresponding to the first picture for inter picture prediction, a second picture whose quantization has been started or completed is also replaced with the copy picture.
