Summary:PROBLEM TO BE SOLVED: To provide a technique for allowing a user to easily and precisely adjust a focus.SOLUTION: An image for adjustment including a part showing a predetermined pattern is projected with projection light. Image data is generated by imaging a projection plane on which the image for adjustment is projected. A focusing state of a focus on the projection plane is identified by analyzing the image data. A display is made in the identified focusing state. 【課題】ユーザが容易に精度良く焦点を調整することを可能にする技術を提供することを目的とする。【解決手段】投写光によって所定のパターンを表す部分を含む調整用画像を投写する。調整用画像が投写された状態の投写面を撮像して画像データを生成する。画像データを解析することによって、投写面における焦点の合焦状態を特定する。特定された合焦状態を表示する。【選択図】図４
