In spite of the permanent advances in electronic particle detectors, the X-ray emulsion chambers (XREC) still remain a unique tracking detector which enable cosmic ray physicists to create large-scale set-ups (up to a few thousand square meters) at mountain altitudes and to study with them a fine structure of EAS cores resolving most energetic hadrons at distances about 10 microns. To meet hard requirements of large-scale XREC experiments, which imply a labour intensive processing of a huge amount of X-ray films, a new fully automatic experimental technique of X-ray film processing is developed. It is based on high temperature film development using an automatic large-format processor (particularly, Colenta ImageLine-56S) and subsequent scanning of films with a high-end image CCD-scanner, e.g., Dainippon Screen Sezanne Elite FT-S5500, possessing both high spatial (~5 m) and optical (16 bit, Dmax=4.) resolution. All the measurements of track coordinates, arrival angles and optical densities of darkening spots are done by digital processing of corresponding graphic files taking advantage of modern computer technologies of image recognition and image handling. The new technique was successfully approved by processing of X-ray films recently exposed in a 2-storied XREC at Tien Shan High Mountain Scientific Station. The first results of application of this technique are presented and compared with corresponding ones obtained with the conventional technique. The innovative technique enables researchers not only to speed up drastically the experimental data processing but also to increase considerably the accuracy of measurements and reliability of obtained results.
