A universal semi-empirical method for photometry of low light level meteors and earth artificial satellites is proposed. The method was developed for photometrical measurements and reductions of images obtained with the help of TV systems of super-isocon type known by its non-linear response onto input signal and long afterimage in TV frames from dynamical objects. Semi-empirical approach has appeared in that the photometrical dependencies of TV system for moving and stationary objects were investigated with the test of photographing of star sky with the camera which was rotating with different angular velocity including stationary state. Basing on obtained results the calibration curve was plotted, and the light curve of a meteor from range of 4—7 magnitude was calculated. The proposed method is universal and can be used for photometrical processing of moving irradiated point objects obtained with any TV or video system
