Scientific paper

The author examines some methods of the photometric treatment of digitized images obtained from TV observations of meteors. The internal error of the photometry caused by the entrance signal fluctuations, noises of the TV system, and inaccuracy of digital treatment methods of the images in a TV frame is investigatged in detail. Source of each type of errors and possible methods for diminishing them are studied. The basic source of internal errors at such short exposure is fluctuations of the signal from the object observed. The sky background fluctuations and the error of measurement method affect the result to a much smaller degree.
