摘要： A method is disclosed for controlling the exposure during photographic printing. The transmission density of a negative or original is measured to provide an exposure control signal. In an illustrative embodiment of this invention, the original is divided into a central portion, a peripheral portion, an upper portion, a lower portion, a right-hand portion and a left-hand portion. Means are provided for quantizing a difference in average density between the portions in the negative, which is classified into a plurality of categories in accordance with a logic of combining characteristic values of the negative. The method affords an enhancement of accuracy in exposure control and an enhancement of probability of obtaining prints of good quality.

摘要： Red, green and blue densities of a number of points on a color negative or original are measured and the measured values are plotted in a coordinate system. When the measured values of the densities are contained in a predetermined region of the coordinate system defined as the flesh color region, the measured point is determined to be of flesh color. When the number of points determined to be of flesh color is not less than 13 among 748 points sampled, for instance, the color original is determined to have a subject matter of a human figure. Then, in printing the color negative the exposure is controlled to reproduce a flesh color of desired color balance and density.

摘要： A plurality of principal-component spectral distributions are determined in advance by analyzing spectral distributions of a multiplicity of sample films; light transmitted through a film to be estimated is measured by spectrally diffracting the transmitted light into wavelengths of different bands or into different wavelength bands the number of the wavelengths or wavelength bands being equivalent to that of the plurality of principal-component spectral distributions; coefficients for expressing the spectral distribution of the film to be estimated as a linear sum of the plurality of principal-component spectral distributions are determined on the basis of photometric values of the respective wavelengths wavelength bands and the plurality of, principal-component spectral distributions; and the spectral distribution of the film to be estimated is estimated by determining the linear sum of the plurality of principal-component spectral distributions by using the coefficients obtained. On the basic of the spectral distribution estimated and by using an effective spectral sensitivity distribution of the copying light-sensitive material, a calculation is made of a transmission density which is equivalent to a transmission density obtained when an image on the film to be printed is photometrically measured by a photometric device having a spectral sensitivity distribution identical to a spectral sensitivity distribution of the copying light-sensitive material; and exposure amount for printing the image on the film to be printed onto the light-sensitive material is determined on the basis of the transmission density calculated.

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.
