Abstract
Description
図1は、実施例1に係る情報機器1の外観を示す図で、(a)は前面図、(b)は背面図である。情報機器1は、カメラ機能とディスプレイ機能を一体化した情報機器であって、例えば、スマートフォン、タブレットPCなどが相当する。その構成は、1aはリターン釦、1bはホーム釦、1cはマルチタスク釦、2はアウト(OUT)カメラ、2aはオートフォーカス(AF)センサ、2b/2cはRGBセンサ/LEDフラッシュ、3はイン(IN)カメラ、4はタッチセンサ一体型のディスプレイ、4aは光センサ、5は受話口である。背面側にあるアウト(OUT)カメラ2では外部の被写体を撮影し、前面側(ディスプレイ4側)にあるイン(IN)カメラ3では自撮りすることができる。以下、情報機器1のことを単に「カメラ」とも呼ぶことにする。
図4Aは、情報機器1の撮影処理の動作フロー(S100)を示す図である。この処理では、オートフレーミング処理により、自カメラの撮影画像とこれに合成する他カメラの画像を選択して保存する。
図7Aは、図4Aの撮影画像表示状態(S103)での表示画面を示す。カメラ1のディスプレイ4には、ユーザAのカメラの撮影画像41と、ユーザがAであることを示すユーザマーク411、カメラ画像共有サービス釦412、シャッタ釦413、設定釦414が表示されている。ユーザAは、カメラ画像共有サービス釦412を押すことで、カメラ画像共有サービス13へのログインを開始する。
図12Aと図12Bは、撮影時の合成画面の表示状態を示し、図11におけるステップS109に対応する。図12Aは、横画面でカメラ撮影を行い、OUTカメラ2の画像48とINカメラ3の画像47を横方向に並べて表示するフレーミングパターンが適用されている(S108a)。撮影画像の選択(S110a)では、選択釦482をチェックし、OUTカメラ2の画像48を選択している。
