Abstract

The structure of CCD imagers and peculiarities of their operation modes allows us to realize the control of such CCD characteristics as sensitivity and resolution, and to minimize spurious signals from image sensors which appear in the image detection process. In many cases there is an apriory information about parameters of dynamic images, for example, the velocity vector or the law of objects brightness variation, allowing us to optimize CCD sensor operation mode. The following control methods of CCD imager characteristics are considered in the paper: (1) shift compensation methods, time delay and integration mode, which are met for detection of moving objects images; (2) increase methods of time resolution of CCD imagers which are aimed at quick process detection; (3) control methods of CCD sensitivity in the integration process for the false components rejection in the image caused by insufficient field frequency. Experimental data obtained during the research of considered methods are given in the paper.
