Summary: | PROBLEM TO BE SOLVED: To reduce a user's burden in color tone adjustment including white balance adjustment.SOLUTION: A white balance adjustment mode is activated when a white balance button has been operated. An image picked up by a scope is acquired as an image for white balance adjustment (step S100). Whether or not an insertion part's tip has been inserted inside a white balance adjustment cylinder is determined depending on whether or not the whole acquired image is approximately uniformly white (step S104). The white balance adjustment cylinder's bottom surface outline is extracted from the acquired image; whether or not the tip's position is at an appropriate position from the bottom surface is determined depending on whether or not the outline's size is predetermined one (step S106). When it is determined that the insertion part's tip is inside the white balance adjustment cylinder and the tip is appropriately distant from the bottom surface, white balance adjustment processing is automatically executed (step S108).SELECTED DRAWING: Figure 4
【課題】ホワイトバランス調整を含む色調調整におけるユーザの負担を軽減する。【解決手段】ホワイトバランス・ボタンが操作されると、ホワイトバランス調整モードを起動する。スコープで撮影される画像をホワイトバランス調整用画像として取得する(ステップS100)。取得画像全体が略均一な白色であるか否かにより挿入部先端がホワイトバランス調整筒内に挿入されたか否かを判断する(ステップS104)。取得画像からホワイトバランス調整筒の底面輪郭を抽出し、その大きさが所定の大きさであるか否かにより先端の位置が底面から適正な位置にある否かを判断する(ステップS106)。挿入部先端がホワイトバランス調整筒内にあり、かつ先端が底面から適正な距離にあると判断される場合に、自動的にホワイトバランス調整処理を実行する(ステップS108)。【選択図】図4 |
