    Patent number: 4563740
    Abstract: The display Gray level in a video display of a computer tomography system is changed at a rate which is non-linearly proportional to the rate of pulses generated by a manually operated control such as a track ball thereby accelerating change in the Gray level when a large change is desired and decelerating change in the Gray level when exact positioning is desired. Control of the rate of change can be by programmed computer or by hardwired logic.
