Abstract:
1. A method for processing image data, comprising (a) providing a first multiplier, a second multiplier, a first adder, a second adder, a third adder and a fourth adder, with respect to a hardware processing timing with multiple time terms, with respect to a time axis having multiple time points, wherein a T(2n+1) group of the time terms are the odd time points along the time axis and a T(2n) group of the time terms are the even time points along the time axis, where n is a zero or an integer; (b) using the T(2n+1) time terms of the first and the second adders, and the T(2n) time terms of the first multiplier to process the hardware timing, and thus generating a first stage data Y based on a source image data X (c) using the T(2n+1) time terms of the third adders, and the T(2n) time terms of the second multiplier and the fourth adder to process the hardware timing, and thus generating a second stage data Z based on the first stage data Y and the source image data X (d) using the T(2n) time terms of the first and the second adders, and the T(2n+1) time terms of the first multiplier to process the hardware timing, and thus generating a third stage data H based on the first stage data Y and the second stage data Z; (e) using the T(2n) time terms of the third adder, and the T(2n+1) time terms of the second multiplier and the fourth adder to process the hardware timing, and thus generating a fourth stage data L based on the second stage data Z and the third stage data H; (f) multiplying the third stage data H with a first corresponding coefficient to obtain detailed coefficients; and (g) multiplying the fourth stage data L with a second corresponding coefficient to obtain smooth coefficients.
