AUTOMATIC CORRECTION DEVICE OF PHOTOGRAPH PRINTING AND DEVELOPING APPARATUS

PURPOSE: An automatic correction device installed in the photograph printing and developing apparatus is provided for automatically controlling printing degree by comparing color, density or image of film input with reference data memorized in PC and determining the optimum values. CONSTITUTION: The automatic correction device equipped in the photograph printing and developing apparatus to correct light beam passing through the filter and scatter the corrected beam comprises the light sensor to detect the beam output; the nega sensor between the filter and the zoom lens to detect B, G, R output from the beam; CCD camera between the filter and the zoom lens to take picture when a portion of the beam passed through the filter is reflected toward the prism; and PC to compare the detected signals from the light sensor and nega sensor with images given by CCD camera and optimally correct color or density of the film.
