    • The digital signal recording apparatus of the invention for recording a video signal on a recording medium, includes: a mode setting section for setting a recording mode, the recording mode being one of a standard recording mode and a long-time recording mode having a longer recording time than that of the standard recording mode; a sampling section for sampling the video signal at a sampling number corresponding to the recording mode set by the mode setting section, the sampling number when the selected recording mode is the long-time recording mode being smaller than the sampling number when the selected recording mode is the standard recording mode; a coding section for coding the video signal sampled by the sampling section at a compression rate corresponding to the recording mode set by the mode setting section, the compression rate when the selected recording mode is the long-time recording mode being higher than the compression rate when the selected recording mode is the standard recording mode; and a recording section for recording the video signal coded by the coding section on a recording medium.
    • 本发明的用于在记录介质上记录视频信号的数字信号记录装置包括:模式设置部分,用于设置记录模式,记录模式是标准记录模式和长时间记录模式之一 录制时间高于标准录音模式; 采样部分,用于以对应于由模式设置部分设置的记录模式的采样数采样视频信号,当所选择的记录模式是长时间记录模式时,当所选择的记录模式 是标准录音模式; 编码部分,用于以与由模式设置部分设置的记录模式对应的压缩率对采样部分采样的视频信号进行编码,当所选择的记录模式是长时间记录模式时的压缩率高于压缩率 当所选择的记录模式是标准记录模式时; 以及记录部分,用于将由编码部分编码的视频信号记录在记录介质上。

    • Plural pictures recorded on an optical film are read, in frame units, by a scanner 11 to convert them into electric picture data to store those picture data into a main memory 21. A memory control section 2 controls read-out and write-in operations of the picture data obtained from the scanner 11 with respect to the main memory 21. Further, the memory control section 2 controls the write-in and read-out operations of the picture data to thereby obtain inverted picture data in which (relative position of) the picture data is inverted in regard to upper and lower directions thereof. A system control section 5 controls the memory control section 2 in accordance with inverting command from a keyboard 6 so as to obtain inverted picture data. Since the write-in or read-out operation of the picture data with respect to the main memory 21 is controlled by the system control section 5 so as to invert (relative position of) picture data in regard to upper and lower directions thereof in accordance with the inverting command from the keyboard 6, in the case where inverted picture in which the upside is turned down is displayed on a display section 7, the inverting command is given, thereby making it possible to display, on the display section 7, erecting (normally standing) pictures of respective frames in which relative position in regard to upper and lower directions is inverted, and to record the erecting pictures of respective frames onto a recording medium by a disc drive 42.
    • 通过扫描器11以帧为单位读取记录在光学薄膜上的多张图像,将其转换成电子图像数据,将这些图像数据存储到主存储器21中。存储器控制部分2控制读出和写入操作 从扫描器11获得的相对于主存储器21的图像数据。此外,存储器控制部分2控制图像数据的写入和读出操作,从而获得反转的图像数据,其中(相对位置 )图像数据相对于其上下方向反转。 系统控制部分5根据来自键盘6的反转命令控制存储器控制部分2,以获得反转的图像数据。 由于图像数据相对于主存储器21的写入或读出操作由系统控制部分5控制,以便根据图像数据的上下方向反转(相对位置)图像数据 利用来自键盘6的反转命令,在显示部分7上显示反转图像的情况下,在显示部分7上显示反转命令,从而可以在显示部分7上显示直立 (相对于上下方向的相对位置)反转的各帧的(通常站立)图像,以及通过盘驱动器42将各帧的竖立图像记录到记录介质上。
