Summary:PROBLEM TO BE SOLVED: To prevent positional information of an indication body from being output to an unintended output destination even if the input source of a picture is changed.SOLUTION: If the relation between a first interface for inputting an image signal and a second interface for outputting positional information is not stored when positional information is to be output (S20:NO), whether the candidate of the second interface is uniquely determined is determined (S40). If the candidate is not determined uniquely (S40:NO), an output destination confirmation image is displayed (S50), and the output destination selected on the output destination confirmation image is stored in a management table TBL (S60). If the relation between the first and second interfaces is stored (S20:YES), whether "no output destination" is stored in a management table TBL is determined (S80), and if there is an output destination (S80:NO), processing for sending the positional information is performed (S90).SELECTED DRAWING: Figure 6 【課題】映像の入力元を変更しても指示体の位置情報を意図しない出力先に出力させない。【解決手段】位置情報の出力の際、画像信号を入力する第１のインターフェースと、位置情報を出力する第２のインターフェースの対応付けが記憶されていない場合には（Ｓ２０：ＮＯ）、第２のインターフェースの候補が一意に定まるか判定する（Ｓ４０）。一意に定まらない場合には（Ｓ４０：ＮＯ）、出力先確認画像を表示させ（Ｓ５０）、出力先確認画像上で選択された出力先を、管理テーブルＴＢＬに記憶させる（Ｓ６０）。第１のインターフェースと、第２のインターフェースの対応付けが記憶されている場合には（Ｓ２０：ＹＥＳ）、出力先無しが管理テーブルＴＢＬに記憶されているかどうかを判断し（Ｓ８０）、出力先無しではない場合には（Ｓ８０：ＮＯ）、位置情報の送信処理を行う（Ｓ９０）。【選択図】図６
