Results of CCD frames of star fields processing obtained by two ways, are analyzed. In the first case (a traditional method) the frame of flat field are used. In the second one the own large-scale flat field is obtained directly from the processable frames of image. That is we suggest to find the frame of a flat field individually for each frame of the image. Photometric researches of regular errors are carried out for a wide interval of exposures (up to 100 times) for the same celestial objects in zones of overplanning of displaced frames (up to half of the frames size). Comparison of an instrumental photometric scale with a scale of photometric standards shows the absence of photometric field errors and brightness errors. Software procedure of cyclic processing of any quantity of CCD frames of star fields is realized in program shell of MIDAS/ROMAFOT.
