Description

本発明に係る画像処理装置は、動画データを入力する入力手段と、動画データの記録開始からの経過時間を示すタイムコードを生成する生成手段と、前記入力手段により入力された動画データと前記生成手段により生成されたタイムコードとを記録媒体に記録する記録手段であって、記録開始の指示に応じて前記動画データの記録を開始し、記録停止の指示に応じて前記動画データの記録を停止する記録手段と、前記入力手段により入力された動画データと前記生成手段により生成されたタイムコードとを外部記録装置に出力する出力手段と、前記記録開始の指示に応じて前記外部記録装置に記録開始コマンドを出力し、前記記録停止の指示に応じて前記外部記録装置に記録停止コマンドを出力するように、前記出力手段を制御する制御手段とを備え、前記記録開始の指示に応じて、前記生成手段により前記タイムコードのカウントを所定値から開始すると共に、前記出力手段により前記外部記録装置に対して前記カウントされたタイムコードの出力を開始し、前記記録停止の指示により前記記録手段が前記動画データの記録を停止した後に前記生成手段による前記タイムコードのカウントを継続すると共に、前記出力手段による前記外部記録装置への前記タイムコードの出力を継続することを特徴とする。 The image processing apparatus according to the present invention, the input means for inputting moving image data, and generate means for generating a time code indicating the elapsed time from start of recording the moving image data, moving image data and input by the input means a recording means for recording the time code generated by generate means on a recording medium, start recording the moving image data according to an instruction to start recording, the recording of the moving image data in response to the recording stop instruction and recording means for stopping, and output means for outputting the time code generated by the moving image data and the raw formed unit inputted by said input means to an external recording device, said external recording according to an instruction of the recording start device to output a recording start command, to output a recording stop command to the external recording device in accordance with an instruction of the recording stop, the control means for controlling said output means Wherein the in accordance with the recording start instruction, and starts from the predetermined value more counts of the time code in the raw forming means, an output of the counted time code to the external recording device by said output means was started, the with the recording means by the recording stop instruction to continue the counting of the time code by prior Symbol raw formed unit after stopping the recording of the moving image data, to the external recording device by said output means characterized by continuing the output of the time code.

操作部１０７により記録停止の指示があると（Ｓ２０５）、制御部１０６は、ＧＯＰの最終フレーム、即ち、図３のＧＯＰ構成３０１におけるＰ１１フレームまで記録したか否かを判別する（Ｓ２０６）。ＧＯＰの最終フレームまで記録していない場合（Ｓ２０６）、ビデオカメラ１００は、動画データの符号化と記録を続け（Ｓ２１３）、動画データにタイムコード生成部１１１によるタイムコードを付加してレコーダ２００に出力する（Ｓ２１４）。タイムコード生成部１１１がタイムコードをカウントアップし、Ｓ２０６に戻る（Ｓ２１５）。 When an instruction to stop recording is given by the operation unit 107 (S205), the control unit 106 determines whether or not the last frame of the GOP, that is, the P11 frame in the GOP configuration 301 in FIG. 3 has been recorded (S206). When the GOP has not been recorded until the last frame (S206), the video camera 100 continues to encode and record the moving image data (S213), and adds the time code by the time code generation unit 111 to the moving image data to the recorder 200. Output (S214). The time code generation unit 111 counts up the time code and returns to S206 (S215).
