Title
(EN) PROJECTION TYPE DISPLAY DEVICE AND METHOD FOR PRODUCING RECORDED IMAGES
(FR) DISPOSITIF D'AFFICHAGE DE TYPE PROJECTION ET PROCÉDÉ DE PRODUCTION D'IMAGES ENREGISTRÉES
(JA) 投写型表示装置および記録画像生成方法
Abstract
(EN)
This projection type display device includes a projection means that projects an input image that shows an object on the background according to an input image signal on a projection surface on which a user writes information, and a processing means that stops projection by the projection means when an imaging instruction is received, images the projection surface, generates an imaged image, detects differences between the background color within the input image and color of the projection surface within the imaged image, generates a corrected image by correcting the color of one image of the input image and imaged image such that the difference is made smaller, and generates an image to be recorded by superimposing the other image and the corrected image.
(FR)
Ce dispositif d'affichage de type projection comprend un moyen de projection qui projette une image d'entrée qui affiche un objet en arrière-plan conformément à un signal d'image d'entrée sur une surface de projection sur laquelle un utilisateur écrit des informations, et un moyen de traitement qui arrête la projection par le moyen de projection lorsqu'une instruction d'imagerie est reçue, image la surface de projection, génère une image imagée, détecte les différences entre la couleur d'arrière-plan au sein de l'image d'entrée et la couleur de la surface de projection au sein de l'image imagée, génère une image corrigée en corrigeant la couleur d'une image de l'image d'entrée et de l'image imagée de sorte que la différence soit plus petite, et génère une image à enregistrer en superposant l'autre image et l'image corrigée.

 投写型表示装置は、入力映像信号に応じた背景上のオブジェクトを示す入力画像をユーザが情報を書き込む投写面に投写する投写手段と、撮影指示を受け付けると、投写手段による投写を停止して投写面を撮影し撮影画像を生成し、入力画像内の背景の色と撮影画像内の投写面の色との違いを検出し、該違いが小さくなるように、入力画像と撮影画像とのうちの一方の画像の色を補正して補正画像を生成し、他方の画像と補正画像とを重畳して記録画像を生成する処理手段と、を含む。
