METHODS OF STABILIZATION

Abstract

The article is devoted to the analysis of methods of stabilization of photo-video camera and image, advantages and disadvantages of different methods of camera stabilization in order to improve the quality of photo and video shooting. The optical image stabilization system is an automated control system. In its composition, it must have a motion sensor, such as a gyroscope or accelerometer, analog or digital computing device and an actuator for motion compensation (motor). The purpose of such a control system is to maintain a fixed position relative to the inertial coordinate system, line of sight or light beam that passes through the camera lens and falls on the light-sensitive matrix. It is possible to realize it by means of the electric motor on the basis of the information from sensors. The electric motor rotates a certain stabilized optical unit, which in turn refracts the light beam. This unit is made with the possibility of rotation around the vertical and horizontal axes or the axes of the course and pitch. The optical unit rotates so that the projection of the image on the film or light-sensitive matrix fully compensates for camera shake during exposure. As a result, the projection always remains stationary with respect to the light-sensitive matrix for small oscillations of the camera. This provides the necessary image clarity. The steadic camera stabilization device provides smooth camera movement in different planes. Steadicams are used in film and video shooting, as it is the easiest way to get a quality picture in motion without shaking with minimal cost. To ensure high accuracy of image stabilization, it is proposed to use an optical stabilization system based on image stabilization. It can be used for photo and video equipment and even in systems such as binoculars and sights.
