Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a projector that allows a user to easily recognize the state of lens adjustment even when the user has difficulty recognizing a projection image.SOLUTION: A projector 1 includes: a light source (light source device 11); light modulation devices (liquid crystal light bulbs 12R, 12G, and 12B) that modulate light emitted from the light source into image light according to image information; a projection lens 13 that projects the image light modulated by the light modulation devices; a display unit 28 that is provided on the main body of the projector 1; a plurality of lens adjustment mechanisms (focus adjustment mechanism 131, zoom adjustment mechanism 132, and lens shift adjustment mechanism 133) that perform a plurality of types of adjustment to the projection lens 13; selection units (focus adjustment start key B3, zoom adjustment start key B4, and lens shift adjustment start key B5) that cause a user to select one of the plurality of lens adjustment mechanisms; and a control unit 20 that displays information on the lens adjustment mechanism selected through the selection unit on the display unit 28.
【課題】投写画像の視認が困難な場合にも、レンズ調整状況を認識しやすいプロジェクターを提供する。【解決手段】プロジェクター1は、光源(光源装置11)と、光源から射出された光を、画像情報に応じて画像光に変調する光変調装置(液晶ライトバルブ12R,12G,12B)と、光変調装置で変調された画像光を投写する投写レンズ13と、プロジェクター1の本体に備わる表示部28と、投写レンズ13に対して複数の調整を行う複数のレンズ調整機構(フォーカス調整機構131、ズーム調整機構132、レンズシフト調整機構133)と、複数のレンズ調整機構のうちの1つを選択させる選択部(フォーカス調整開始キーB3、ズーム調整開始キーB4、およびレンズシフト調整開始キーB5)と、選択部によって選択されたレンズ調整機構の情報を表示部28に表示させる制御部20と、を備える。【選択図】図2 |
