Abstract: A system for managing information on a carrier, and an image reading apparatus, which enable easy resetting of correction data. When a film carrier is mounted in an image reading apparatus main body, a control section reads the identification number of the film carrier from an EEPROM, and determines whether the identification number corresponds to any of the identification numbers stored in a RAM. When correspondence is not found, it determines that the film carrier is mounted in the main body for the first time, and correction data is read from the EEPROM and stored in the RAM with the identification number. Instead of losing the correction data if the substrate is replaced, the correction data stored in the RAM is read from the control section and written into a new EEPROM, thereby enabling easy resetting of the correction data.

Abstract: A printer prints a calibration pattern on a leading end portion of a roll of recording paper when the recording paper is loaded in the printer. A cutter cuts the leading end portion off the recording sheet so as to make an end edge rectangular to side edges of the recording sheet. A photometric device measures densities of the printed calibration pattern, and a system controller derives correction values for correcting density or color from the measured densities. After the calibration process, an image is printed in an image recording area on the recording paper following the leading end portion. For a printer that prints an image on a cut sheet recording paper, a calibration pattern is printed on a margin outside an image recording area. After densities of the calibration pattern are measured, the margin with the calibration pattern is cut off the recording paper.

Abstract: A process for restoring the color of faded color negative film, particular for faded color motion pictures. The original faded negative film is used to produce a green enhancement mask and a blue enhancement mask (or a combination green/blue enhancement mask). Standard red, green, and blue separations are also made from the original faded negative. By combining the green and blue enhancement masks with the standard green and blue separations, respectively, (or the combination green/blue enhancement mask with the green separations and blue separations), enhanced green and blue separations are created. The enhanced green separation, the enhanced blue separation, and the red separation are recombined to form the restored color negative or interpositive. Alternately, from the original negative, an enhanced blue mask can be created, and intermediate film stock printed with yellow light passed through the original negative to produce unprocessed intermediate stock can be created.
