の映像出力は常時モニター６に入力せしめる。V2. V2. . . , the related television cameras 1, 2, . . . The video signal into which the digitized number 12 that displays ... is inserted is sequentially recorded at fixed time intervals on the VTR 9, and as shown in FIG.
Select number discriminator 13 to select VTR video output signal 0 from 9
is input to the gate 14, and the selection number discriminator 13 is controlled according to the selection number from the selection video number generation section 15. For example, when the selection video number generation section 15 selects the video v1 of the camera 1, the VTR video When the digitized number of the output signal matches it, a number match signal 16 is generated, which opens the gate 14 and outputs the VTR video output signal 10.
is sent to the digital frame memory 17 through the gate 14 and written in the frame memory, and the video output of this frame memory is always input to the monitor 6.
本発明の映像選択再生装置は上記のような構成であるか

示されるがカメラｌの映像が終わり、カメラ２の映像信
号Ｖ２が始まると選択番号判別部１３からは番号合致信
号１６が発生しないためゲート１４は閉じられ、フレー
ムメモリー１７の書き込みが禁止されるため、フレーム
メモリー１７は既に記録されているカメラ１の映像の最
後のフレーム映像を送り出し続けることになる。Since the video selection playback device of the present invention has the above configuration, the video is displayed on the monitor 6 while the video from camera 1 continues, but when the video from camera l ends and the video signal V2 from camera 2 starts. Since the number matching signal 16 is not generated from the selection number discriminator 13, the gate 14 is closed and writing to the frame memory 17 is prohibited, so the frame memory 17 stores the last frame image of the already recorded image of the camera 1. will continue to be sent out.
時間が経過して再びカメラ１の映像が始まると再びカメ
ラ１のデジタル化番号１２が表れる為、選択番号判別部
１３から番号合致信号１６が発生しゲート１４が開き、
フレームメモリー１７が書き込みを始め、新しいカメラ
１の映像をモニター６に表示し始めることになる。When time passes and the image of camera 1 starts again, the digitized number 12 of camera 1 appears again, so the number match signal 16 is generated from the selected number discrimination section 13 and the gate 14 is opened.
The frame memory 17 starts writing, and the new camera 1 image starts to be displayed on the monitor 6.
以上の繰り返しにより、カメラエの映像のみ選択して見
