Claims (1)
- デジタル/アナログ放送信号を受信する受信手段と、前記受信手段により受信したデジタル/アナログ放送信号から映像信号を抽出するデコーダと、前記デコーダにより抽出された1フレーム分の映像信号をキャプチャ画像として記憶する静止画キャプチャ装置と、前記デコーダにより抽出された前記映像信号及び前記静止画キャプチャ装置により記憶された前記キャプチャ画像を表示手段に出力する出力手段とを備えたデジタル/アナログチューナ装置であって、
前記静止画キャプチャ装置は、前記デジタル/アナログチューナ装置を制御するCPUと、キャプチャ画像を記憶するメモリと、CPUの動作プログラムを格納するROMとを備え、CPUによる制御のもと、メモリへのキャプチャ画像の記憶時に、前記映像信号の解像度及び放送の種類に応じて、該映像信号のVBI(Vertical Blanking Interval)部をカットしてキャプチャ画像として記憶すると共に、該キャプチャ画像に関するアスペクト比情報を記憶し、
前記出力手段は、前記キャプチャ画像を前記表示手段に出力する際に、前記VBI部をカットした後のキャプチャ画像を出力すると共に、該キャプチャ画像が前記アスペクト比情報とは異なるアスペクト比で前記表示手段に表示される場合に、CPUによる制御のもと、該キャプチャ画像が変形しないように、前記アスペクト比情報に応じたブランク部分を前記キャプチャ画像に付加して出力することを特徴とするデジタル/アナログチューナ装置。
