Patent Number: 6,310,917

Title: Picture coding method

Abstract: When fade-in is detected at a time (.tau.f), the remaining number of bits (R) is increased by Rup=G/2. Thus, the remaining number of bits R to be consumed in the GOP (n) becomes (3/2)G=(12/8)G. In this way, the remaining number of bits (R) is increased when fade-in is detected. This increases the bit rate in pictures coming after fade-in and requiring a large information content, thereby improving picture quality.
