摘要： The exposure of a camera is controlled based on the scene brightness measured by use of a number of light measuring elements located at positions to receive light through from the scene. The light receiving area is divided into several zones. In each of the zones, at least one light measuring element is provided to measure the brightness of the scene in each zone and are used to give the maximum or minimum brightness (Bzi) in each zone. Exposure is controlled based on a weighted mean value ##EQU1## (K.sub.i+2 is a coefficient). In a preferred embodiment of the invention, another brightness (B.sub.0) such as a simple mean value of the outputs of all the light measuring elements is obtained, and the exposure is controlled based on the scene brightness B determined by the formula of ##EQU2##

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： In a digital printer, a great number of images recorded on the same type recording medium as an original to be reproduced are roughly pre-scanned prior to main scanning of the original. The pre-scanning image data is sorted according to green density levels, and red and blue densities of those pixels which are selected according to a standard are respectively accumulated for each green density level. Mean values of the red and blue densities accumulated in the respective green density levels are used as the pixel selection standard. Different kinds of gradation balance data are obtained by use of different methods from the mean values of the accumulated image data and/or image data of the original, to derive optimum gradation balance data from these different kinds of gradation balance data by selecting and combining the data. A gradation conversion table is produced from the optimum gradation balance data and previously stored gradation curve data. Main scanning image data of the original is converted through the gradation conversion table.

A reference image recorded on the film is photometrically measured to determine film characteristic data. After transformed values of an original image have been stored normalizing conditions are determined, and a transformation formula or table is generated in correspondence with a film type. Pixels are then selected from the original image set in the printing position, and a characteristic amount of the image is calculated and made to correspond to print characteristic data. An abnormal frame is then determined, and an exposure amount is determined by setting coefficients of an exposure calculating formula. Also disclosed is a color copying apparatus for constantly obtaining a high-quality print on the basis of the density of a reference image and the density of a print frame. A reference image recorded on the film is photometrically measured to determine film characteristic data. After transformed values have been stored, normalizing conditions are determined, and corrected film characteristic data is determined in correspondence with a film type. Pixels are then selected from the original image, and a characteristic amount of the image is calculated to determine a reference density for controlling the exposure of the print frame.

摘要： 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. In an exposure condition determining device, exposure conditions are determined based on reference exposure conditions input from a reference exposure condition setting device, photometric data selected by a photometric value selecting device, and the above-described correction value. Accordingly, images having proper image quality can be reproduced from various films having different film characteristics.

摘要： A photographic printing method for printing a film image onto photographic paper by estimating the color temperature of a subject illuminant, and by changing, in correspondence with the color temperature estimated, a degree of correction of the image density in which an improper color balance occurs in color reproduction with a change in the color temperature of the subject illuminant. By changing the degree of correction in correspondence with the estimated color temperature, it is possible to allow the hues of the subject illuminant to be reflected on the prints. In addition, it is also possible to change the degree of correction in correspondence with the light-source-color information indicative of the photographer's intent in expressing the hues of the original scene. Furthermore, the light quality of the subject illuminant can be estimated from data on the date and time of photographing, a photographed district, a light value at the time of photographing, and information indicative of whether or not an electronic flash was used at the time of photographing, and print exposure amount can be determined in correspondence with the light quality estimated. In addition, by estimating the light quality of the subject illuminant and by determining an average image density from image densities of a plurality of frames photographed under a subject illuminant having specific light quality, it is possible to determine print exposure amount by using the average image density as a reference density.
