    • A video monitoring system for a movie film camera usable with either spherical or anamorphic lenses wherein conventional, unmodified video monitors and recorders may be used. A video camera is positioned in the film camera to receive an image directly from the camera lens without interposing either a ground glass for imaging or an optical deanamorphosing lens. The anamorphic image, which is horizontally squeezed (such as by a factor of 2), that is received by the video camera then is electronically processed to deanamorphose the image by producing an analog video signal to a video monitor that displays the properly proportioned image in the middle one-half of the monitor screen and produces black areas or strips across the top one quarter and bottom one quarter of the screen. The horizontal lines of the video picture are electronically interpolated for enhancing the picture.
    • 可以使用可以使用球形或变形透镜的电影胶片相机的视频监视系统,其中可以使用传统的未修改的视频监视器和记录器。 视频摄像机位于胶片摄像机中,以直接从摄像机镜头接收图像,而无需插入用于成像的磨砂玻璃或光学去角质变焦镜头。 由摄像机接收的水平挤压(例如2倍)的变形图像被电子处理,以通过产生模拟视频信号去形成图像,以将视频监视器显示在正确比例的图像中 是显示器屏幕的中间一半,并在屏幕的前四分之一和下四分之一处产生黑色区域或条纹。 视频图像的水平线被电插值以增强图像。
