Description
総ドット数=縦×横×RGB=480×640×3=921600
である。
ある画素を2フレームに1度補正した場合、輝度の平均を標準的な画素の輝度と等しくするためには、式1が成り立つようなVgs2をパネルに入力すればよい。ここで、Vgs1は補正しない駆動トランジスタのソース・ドレイン間電圧であり、Vgs2は補正した電圧である。なお、補正しない駆動トランジスタのソース・ドレイン間電圧Vgs1が対象画素の画像データに対応し、補正した駆動トランジスタのソース・ドレイン間電圧Vgs2が補正後の画像データに対応する。
[式1]
{f(a1(Vgs1−b1))+f(a1(Vgs2−b1))}/2
=f(a(Vgs1−b))
[式2]
{a1 c(Vgs1−b1)c+a1 c(Vgs2−b1)c}=2ac(Vgs1−b)c
[式3]
Vgs2 ={2ac(Vgs1−b)c−a1 c(Vgs1−b1)c}1/c/a1+b1
ある画素を4フレームに1度補正した場合、輝度の平均を標準的な画素の輝度と等しくするためには、式4が成り立つようなVgs2をパネルに入力すればよい。
[式4]
{3f(a1(Vgs1−b1))+f(a1(Vgs2−b1))}/4
=f(a(Vgs1−b)
[式5]
{3a1 c(Vgs1−b1)c+a1 c(Vgs2−b1)c}=4ac(Vgs1−b)c
[式6]
Vgs2 ={4ac(Vgs1−b)c−3a1 c(Vgs1−b1)c}1/c/a1+b1
上述の式において、係数cは通常2から3の間の値をとり、[式3]及び[式6]を実現するハードウエアはかなり複雑となる。従って、補正値が比較的小さいとし、次のようにTaylor展開した式の一次の項まで計算して近似的な補正係数を求めて用い、回路を簡略化することもできる。ムラのレベルがそれほど大きくないときはこのようなラフな近似でもムラは大幅に改善できる。
Vgs2 ={2a(Vgs1−b)−a1(Vgs1−b1)}/a1+b1
= Vgs1(2a−a1)/a1−2(ab−a1b1)/a1
この場合、図10の回路構成で、
[式7]
offset=2(ab−a1b1)/a1
[式8]
gain=1+2(a/a1−1)
を用いて補正すればよい。
Vgs2={4a(Vgs1−b)−3a1(Vgs1−b1)}/a1+b1
= Vgs1(4a−3a1)/a1−4(ab−a1b1)/a1
この場合、図10の回路構成で、
[式9]
offset=4(ab−a1b1)/a1
[式10]
gain=1+4(a/a1−1)
を用いて補正すればよい。
[式11]
offset=m(ab−a1b1)/a1
[式12]
gain=1+m(a/a1−1)
で求まる。
[式13]
y_offset(i,j)=offset(i,j)+3{offset(i,j)−Av_offset(p,q)}
[式14]
y_gain(i,j)=gain(i,j)+3{gain(i,j)−Av_gain(p,q)}
ここで、y_offset(i,j)、Av_offset(p,q)はそれぞれ、座標(i,j)の画素のオフセットに関する補正値yと小領域の補正値の平均Avで、gain(i,j)、Av_gain(p,q)はそれぞれ座標(i,j)の画素のゲインに関する補正値yと小領域の補正値の平均Avである。offset(i,j)及びgain(i,j)は、それぞれ、座標(i,j)の画素における式9、式10でもとまるoffset、gainに相当する。
