Abstract
In a fast frame recorder having (1) a video camera adapted to produce signals corresponding to a variety of frame rates, (2) a variable speed tape recorder adapted to down-convert the frame rate of the camera signals to a reference frame rate by appropriately reducing the recorder tape speed to a reference speed, and (3) a display monitor adapted to receive the reference frame rate signals, the camera thereof may be adjusted for various scene and frame rate conditions without need to record the camera frame rate signals (for purposes of signal down-conversion). This is, in accordance with the invention, achieved by selecting a certain line (or lines) from each frame of the camera output signal, and applying such selected lines directly to the display monitor. Skipping from line to line in the camera output signal has the effect of down-converting the frame rate of the camera output signal as required. Thus, tape recording for camera set-up purposes is obviated and, attendantly, the camera may be operated at any selected rate while, at the same time, the camera optics, scene lighting, etc., may be adjusted to optimize the monitor display.
