Abstract
Description
なお、受光量が低い受光センサの位置に基づき、残余部の画素における画像の表示を実行するか否かが決定されてもよい。残余部の画素により適切に画像を表示することが可能であるか否かが判断されることで画像が適切に表示される。
受光センサは画素領域内に格子状に並設されるようにしてもよい。これにより、遮蔽物が覆う範囲を詳細に特定して画像を適切に表示させることが可能となる。
また、画素領域の一部における受光センサでの受光量が基準値以下であって他の一部との受光量の差が所定値以上であるときに遮蔽物が存在すると判断するようにしてもよい。
この場合、選択されなかった画像は残余部にて間欠的に表示されてもよい。
