Abstract: PURPOSE: An IDCT(Inverse Discrete Cosine Transform) method is provided to perform an operation only when a substantial calculation process is necessary, by using characteristics of coefficients incoming as IDCT inputs, thereby reducing IDCT calculations without deterioration of picture quality. CONSTITUTION: A leading1 counter(14) calculates the number of the first '1' from a zero vector(13). The first '1' of the zero vector(13) is in '0' row, and row addresses are increased. An adder(16) adds '1' and the number of rows to be skipped from a previous address, and obtains an address of a next row to be calculated. The zero vector(13) has a shifter(15). The shifter(15) shifts the zero vector(13) to the left, and fills the number '1'. If the zero vector(13) has all '1', the first IDCT is terminated. In the first step, a leading1 count becomes '0', and a next row address becomes 1, loading the first row. The zero vector(13) moves to the left as 1 through the shifter(15), and becomes '11011111' after filling '1'. In the second step, the leading1 count becomes 2, loading the fourth row. The zero vector(13) is shifted to the left as 3, and becomes 11111111.
