ABSTRACT:
A radiographic imaging system and method is disclosed having improved monitor control for enhancing the flexibility of a monitor so that one monitor can perform optimally under several system operating modes. The monitor automically detects the line rate most suitable for producing an image in the selected mode. Brightness compensation is accomplished as a function of the scan line rate at which the monitor is operating. Aspect ratio of the monitor produced image is also adjusted automatically in accordance with the operating mode selected. The system incorporates monitor brightness adjustment as a function of aspect ratio as well. Where the system incorporates a video tape or disk recorder, a time constant of the monitor is adjusted to optimize the monitor's compatibility with the video data output from the recorder in response to the selection of an operating mode wherein the recorder feeds the monitor with video information.
