Abstract

【課題】バッテリー駆動したときに投影時間を長くすることができる走査方式の投影装置を提供する。 【解決手段】バッテリー６００の残量が十分にある場合、アクチュエータ制御部１２０は、通常振り角となるように可動ミラー４３を駆動させ、映像信号処理部１３０は、１画素領域において、所定階調の各レーザ光が通常照射時間ｔ１だけ照射されるように光源部４１を駆動させる。これにより、投影面には、通常画面のサイズの映像が映し出される。一方、電池の残量が少なくなると、アクチュエータ制御部１２０は、小振り角となるように可動ミラー４３を駆動させ、映像信号処理部１３０は、１画素領域において、所定階調の各レーザ光が短照射時間ｔ２だけ照射されるように光源部４１を駆動させる。これにより、投影面には、縮小画面のサイズの映像が映し出される。
