To shorten, in accordance with an operation mode of a display device, a time when the other display device is notified of position information.SOLUTION: A projector 100A comprises: an imaging part 181A for detecting an operation to a screen SC; a coordinate calculation part 183A for calculating position information indicating a position in a display region 10A of the operation detected by the imaging part 181A; and a control part 150A for generating a plotting object on the basis of the position information calculated by the coordinate calculation part 183A, and for displaying the generated plotting object together with a partial image in a display region 10A, therein the control part 150A switches and executes a first operation mode to transmit the position information to the other projector 100 by a USBI/F part 170A and a second operation mode to convert the position information into image position information indicating a position in an image displayed by the screen SC.SELECTED DRAWING: Figure 2 【課題】表示装置の動作モードに対応して、位置情報が他の表示装置に通知される時間を短縮する。【解決手段】スクリーンＳＣに対する操作を検出する撮像部１８１Ａと、撮像部１８１Ａにより検出された操作の表示領域１０Ａでの位置を示す位置情報を算出する座標算出部１８３Ａと、座標算出部１８３Ａが算出した位置情報に基づいて描画オブジェクトを生成し、生成した描画オブジェクトを部分画像と共に表示領域１０Ａに表示させる制御部１５０Ａと、を備え、制御部１５０Ａは、位置情報をＵＳＢＩ／Ｆ部１７０Ａにより他のプロジェクター１００に送信する第１動作モードと、位置情報を、スクリーンＳＣに表示された画像での位置を示す画像位置情報に変換する第２動作モードと、を切り替えて実行するプロジェクター１００Ａ。【選択図】図２
