Description
Tr=IRave/Rave ・・・(式1)
Tg=IRave/Gave ・・・(式2)
Tb=IRave/Bave ・・・(式3)
α=aTr+b ・・・(式4)
β=aTg+b ・・・(式5)
γ=aTb+b ・・・(式6)
Sub_r=max(0,IR−αR) ・・・(式7)
Sub_g=max(0,IR−βG) ・・・(式8)
Sub_b=max(0,IR−γB) ・・・(式9)
上記式(7)〜式(9)に使用した関数max(A,B)は、AとBの大きい方を選択して返す関数である。本実施形態では、IR信号から、R信号に係数αを掛けた値を減算した値がマイナスになった場合、零に置き換える。G信号およびB信号も同様である。
dp=max(0,Sub_b−Sub_r) ・・・(式10)
Sub_r=IR−αR ・・・(式11)
Sub_g=IR−βG ・・・(式12)
Sub_b=IR−γB ・・・(式13)
本実施形態では、部分減算成分Sub同士の差分をとらないため、実施形態3のようにマイナスの値を零に置き換える処理は行わない。
