摘要： First characteristic values of a reference film is stored in a first characteristic value memory, whereas second characteristic values of each type of recording media of the originals is stored in a second characteristic value memory, to produce a gradation balance conversion table for each color from the first and second characteristic values. Image data of an original is converted according to the gradation balance conversion tables, so as to make the color balance proper in all density ranges from highlight through shadow points, even if the original image is under-exposed or over-exposed. The gradation balance converted image data is converted through an image data conversion device into recording data to record a reproduced image as a hard copy of the original.

摘要： A method of making a high-quality print avoids carrying out photometry twice on images on a film. In a first transporting process for transporting the film in a first direction, photometry is carried out on all of the images on the film that are to be copied by dividing the images into a number of pixels, logarithmically transforming thus obtained photometric values into photometric data sets, and storing all thus transformed photometric data sets in correspondence with individual images on the film. At least some of the photometric data sets are used to determine a condition of selection for selecting photometric data of pixels. The photometric data thus selected is used in determining the exposure amount of the images, and photographic prints are made during a second transporting process using the determined exposure amounts.

摘要： A photographic printing method in which a plurality of image frames photographed on a negative film by a camera, which photometrically measures different areas on an object by a plurality of photometric elements and which determines an exposure, is printed onto photographic paper. Printing processing is effected at an average exposure of the plurality of image frames. Namely, all of the image frames of the negative film are photometrically measured. Average densities of each of R, G, and B of an entire image surface are calculated. An average value of the average densities of all of the image frames of the negative film is calculated. An amount of printing exposure is determined using this average value. Printing processing of all of the image frames is effected at this amount of printing exposure. Accordingly, a large proportion of prints having appropriate densities can be obtained.

摘要： A color photographic printing method of printing a film on the basis of the printing condition of a reference film type, comprises comparing the film characteristic of the reference film type with the film characteristic of the type of a film to be printed and correcting the printing condition of the reference film type on the basis of the result of this comparison. Accordingly, the proper printing condition of each type of film to be printed can be obtained from the printing condition of a single reference film type. A color photographic printing apparatus has a light source section for separating white light into red light, green light and blue light by a combination of a color glass and color separation filters of red, green and blue each provided with a dielectric multilayer film to project the light of each color onto a color film and a light measuring device for measuring red light, green light and blue light transmitted through the color film so that the amount of exposure is controlled on the basis of a predetermined reference printing condition and a measurement value provided by the light measuring device. The color separation filters are each constituted by the dielectric multilayer film and a filter member disposed in close contact with the coating of the dielectric multilayer film, it is possible to prevent variations in the spectral characteristic due to temperature changes.

摘要： A method of setting the copying conditions of a color copying machine includes the steps of scanning a test chart having density patterns in three primary colors, to detect three color components of the light reflected from the test chart, based on which three color exposures are obtained. The test chart is scanned again to make a color copy thereof, and the color copy is scanned to detect three color components of the light reflected therefrom, based on which three color densities are obtained. Relationships between the three color exposures and the three color densities are obtained for the three colors. Based on the relationships, three primary color filters are adjusted to regulate three color components of the light passed therethrough, thereby controlling three color exposures.

摘要： An exposure determining device detects densities of a number of picture elements of a color original and displays an image of the color original on a color monitor. A part of a principal subject image of the color original is specified on the color monitor. Based on the measured color density of the specified part, picture elements by which the principal subject image is formed are detected to determine a principal subject image area. By using the detected densities of picture elements included in the prinipal subject image area, at least one image characteristic value is calculated and is used with one of a plurality of previously provided exposure calculating formulas selected according to scenes into which principal subject images are classified, in order to determine the proper exposure for reproducing color images of proper color balance and density.

摘要： In conventional photographic printing process, LATDs are photometrically measured for three primary colors of a color original picture to control the amount of transmitting light at a given level. Although this method of LATD control can produce excellent prints with good color balance for standard color negative films, it often produces defective prints with pool color balance for the original film frames which are dominated with specific colors. This invention method can control the color and the density optimally, remove color failures on objects, and distinguish films influenced with a color of a light source from the films with color failure to thereby provide optimum prints with minimum density fluctuation.
