Abstract
【解決手段】補間処理部105が、4つのラインデータを用いて1つの補間ラインデータを作成するには一定の期間を要するため、1つの補間ラインデータを作成する期間と同じ期間だけ撮像素子101がラインデータを出力せず、補間ラインデータを作成する期間を確保する。これにより、1フレーム分のラインデータ全てが記憶されていなくても、4つのラインデータをラインメモリ106が記憶していれば、ラインメモリ106に記憶されている4つのラインデータを用いて補間ラインデータを補間処理部105が作成することができる。
【選択図】図1
Description
A4=w1・L1+w2・L2+w3・L3+w4・L4
ここで、補間ラインデータA4とラインデータLnとの距離をxnとすると、係数w1、w2、w3、及びw4は以下の式により求められる。
|xn|≦1.0の場合
wn(xn)=(a+2)・|xn3|−(a+3)・|xn2|+1
1.0≦|xn|<2の場合
wn(xn)=a・|xn3|−5a・xn2+8・a|xn|−4a
2.0≦|xn|の場合
wn(xn)=0
