Abstract: An intensity of light emitted from a lamp is passed through a mirror tunnel and is directed to a disk which comprises three, B, G, and R, color filters, each extending 120 degrees on the disk. Each of the B, G, and R modes of light, separated on the disk, is guided through the optical fiber bundle and is transmitted to the PLZT elements. A pattern of the PLZT elements, determined by a group of dots of exposure data to be printed, are energized by a given voltage in synchronization with the rotation of the disk 13, thus allowing a desired mode or wavelength of light to pass selectively and fall efficiently on the printing paper.

Abstract: In an image reproducing apparatus, an image recorded on a negative film is subjected to optical measurement by an optical measuring device. The data obtained by the optical measurement is stored in a photometric data memory for each type of film which is judged by a DX code reader and a film type detecting device. In the apparatus, a difference in characteristics between a reference film and the negative film is calculated by a film characteristic difference calculating device, and the image characteristic amount of the image is calculated by an image characteristic amount calculating device. In a film type correction amount calculating device, a correction value is calculated based on the calculated difference in the film characteristics and the image characteristic amount to compensate for a decrease in the quality of the printed image due to the difference in the film characteristics.

Abstract: The improved method of determining the proper amount of exposure comprises the steps of reading the entire portion of an original image, calculating the characteristic quantities of a principal image in the original image, determining a particular density range from the calculated characteristic quantities of the principal image, extracting only the pixels in said particular density range from the entire portion of the original image to determine the characteristic quantities of the original image, and determining the proper amount of exposure from said characteristic quantities of the original image. When applied to various types of optical image forming apparatus such as copiers, printers and pictographic devices, the method can determine the proper amount of exposure by a simple scanning procedure even if the original to be duplicated is a negative film or other medium having density failure and it hence ensures the formation of the proper and high-quality image in a consistent manner.

Abstract: The color balance of color photographic printing paper is determined by making three successive exposures of separate portions of a sample sheet of printing paper through a neutral-color optical wedge of linear density gradient, each exposure consisting essentially of a different primary color of light of predetermined intensity and duration selectively to stimulate each of the three color-sensitive emulsion layers in the printing paper.

The relative absorptions are arrayed in the form of 3.times.3 mathematical matrices. Solving the matrices in several permutations allows the comparison of actual dye densities that form any one of a number of standard colors with the dye densities that form the image of a test print.

Abstract: A strip of exposed and developed film has a series of exposures and corresponding exposure identification numbers. The strip is conveyed through a scanning station on its way to a printing station. The exposures and identification numbers are scanned in the scanning station to produce output signals indicative of density changes.

Each group includes the position of a respective exposure on the strip, the identification number for the exposure and the position of the identification number on the strip. Film transport is carried out in such a manner that scanning of the strip and processing of the resulting signals are completed before arrival of the strip at the printing station. A control unit uses the data set to position the exposures in the printing station and to print the exposures. The control unit also uses the data set to mark a copy of an exposure with the identification number of the exposure.
