This paper discusses a method of constructing television cameras that use image stabilization based on a direct method of measuring the image displacement relative to a photodetector array by means of two supplementary orthogonal linear photodetectors. It is shown that the proposed approach makes it possible in the parabolic approximation of the correlation function to substantially expand the range of velocities of the viewing axis for which motion distortions are masked by noise.An important task of video informatics is to obtain images of the highest quality when the image is in motion. The approach to the description of various forms of motion of the object and the observer in this case has varied during the development of technologies and concepts. Several characteristic, time-overlapping stages in the construction of video information systems can be distinguished: 727
Methods of controlling the charge-accumulation regime in photodetector arrays have been classified. Differences in methods of controlling accumulation in CCDs and in CMOS structures are considered. A method for adapting the accumulation to the dynamics of the subject and a method for controlling the duration and phase of the accumulation when a distance is measured in a solid-state array system with active pulse illumination are proposed.
In this paper, we consider new approaches when designing video systems with multiple video streams in conformity with the technology of crystal-based video systems combining photoreceiving matrix and computer within one engineering and methodological unity. It is demonstrated by the example of solving the problem of image stabilization that crystal-based video systems with multiple video outputs make it possible to increase the accuracy and speed of image stabilization control loop on the photoreceiving matrix by many times.
