Abstract

In multifunctional video tracking system, a number of specific factors must be considered in the presence of noises to the video signal in order to increase video processing capability for all-weather automatic video control. In fact, since the contrast of the video responses in accordance with different background environments, the signal threshold level and video gain adjustment must be reciprocally considered in a manner for keeping an optimal video source to the processor. In this paper, an adaptive video processor is implemented for all-weather conditions with respect to the auto-threshold control and the auto-gain control. This particular design structure utilizes the different preselection table stored in ROM which is in accordance with the practical contrast and brightness variations to provide an optimal video signal to the tracking system.
