An automatic level and gain control system operable with a sensor to match the dynamic range of the display or other processing elements to the signal provided by the sensor for developing an image with improved dynamic range utilization (or contrast). Peak detection is provided with a conditional integrator so that the effect of high level narrow peaks is substantially suppressed. This system rapidly reaches and maintains a condition of providing the video signal to the display (or other processing) at a desired voltage level and over a desired dynamic range to continually maintain an image having optimum contrast within the dynamic range limitations of the processor or display system.
