    • When a video signal reproduced by a helical scan type video signal reproducing apparatus is displayed on the screen of a liquid crystal matrix circuit, a change in brightness on the screen is eliminated in a mode for displaying a trick reproduced image such as a noiseless search image, a still image or the like with respect to a mode for displaying a normally reproduced image, thus providing the user with displayed images causing a less feeling of strangeness. During normal reproduction, where a video signal is continuously written into a liquid crystal display circuit, the brightness of the liquid crystal display circuit is controlled based on the value in a reference brightness register set by the user. During trick reproduction, where a video signal is discontinuously written into the liquid crystal display circuit, the liquid crystal display circuit is controlled to display an image relatively darker than the value in the reference brightness register. This eliminates the difference in brightness between a normally reproduced image and a trick reproduced image, thereby allowing the user to have a less feeling of strangeness.
    • 当在液晶矩阵电路的屏幕上显示由螺旋扫描型视频信号再现装置再现的视频信号时,在用于显示诸如无噪声搜索图像的特技再现图像的模式中,屏幕上的亮度变化被消除 ,静止图像等,用于显示正常再现图像的模式,从而为用户提供显示较少的陌生感的显示图像。 在将视频信号连续地写入液晶显示电路的正常再现期间,基于由用户设定的参考亮度寄存器中的值来控制液晶显示电路的亮度。 在将视频信号不连续地写入液晶显示电路的特技再现期间,液晶显示电路被控制以显示比参考亮度寄存器中的值更暗的图像。 这消除了正常再现图像和特技再现图像之间的亮度差异,从而允许用户具有较少的陌生感。

    • A VCR integrally provided with a camera (camcorder) stops power supply at a non-recording mode for reducing power consumption. The camcorder is arranged to have power control units and a switch for controlling the start or the end of the recording operation and the power-on or power-off of at least one or more of a camera section, a VCR section and a display section, a time measuring unit, and a control unit for starting the recording unit a predetermined time later than when the camera section starts to pick up an image sequence and the image sequence appears on an electronic viewfinder or the like. Further, the camcorder includes units for moving a zoom lens to a Wide-terminal when powered off, when powered on or a predetermined time later than when powered off. Moreover, there are provided units for overlapping text information with the image sequence appearing on the electronic viewfinder. These units display a time left until the recording start. The camcorder further provides units for varying a predetermined time left until the recording start and units for selecting a moving timing on which the zoom lens is moved to the Wide-terminal so that the user may freely set the predetermined time and the moving timing.
    • 与相机(摄像机)一体设置的录像机在非录制模式下停止供电以降低功耗。 摄像机被配置为具有电源控制单元和用于控制记录操作的开始或结束以及照相机部分,VCR部分和显示部分中的至少一个或多个的上电或断电的开关 ,时间测量单元和用于在比相机部分开始拾取图像序列并且图像序列出现在电子取景器等上的预定时间开始记录单元的控制单元。 此外,摄像机包括用于在电源关闭时,当接通电源或比断电时的预定时间时将变焦镜头移动到宽终端的单元。 此外,提供了用于与文本信息重叠的单元,其中出现在电子取景器上的图像序列。 这些单位显示一段时间,直到录制开始。 摄像机还提供用于改变直到记录开始的预定时间的单位和用于选择将变焦镜头移动到宽终端的移动定时的单元,以便用户可以自由地设定预定时间和移动定时。
