A recording unit 30 records in a recording medium the image data subjected to the image processing by the processing unit 25 or the image data whose image processing has been selected to be not carried out, together with the accompanying information added thereto.

Abstract: 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.

Abstract: 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.

Abstract: During the photographing of an image, photographic data corresponding to the image, such as a photographing date, subject brightness and distance, a shutter speed, an aperture size, data about illumination light, as well as photographic intention data, are recorded on a photographic film. An index code for identifying a recording format of the photographic data is recorded on the photographic film along with the photographic data. During printing, the index code is read out from the photographic film, and one of a plurality of predetermined data conversion tables which are memorized in a printer are selected so as to convert the photographic data into printer codes that can be used in the printer. Then, the photographic data read from the photographic film is converted according to the selected conversion table. Based on the converted photographic data and photometric values obtained from the image to be printed, a print-exposure amount is determined.

Abstract: By the present invention, on the basis of information read from a magnetic recording section of a negative film (Step 200), when it is judged that there are a plurality of negative images to be exposed by the same exposure amount (the judgment in Step 212 is affirmative), a film type is identified to determine the film base density thereof, and a predetermined reference density value is added to the film base density so as to obtain a density control amount which controls the density of a print image (Steps 216 through 220). Thereafter, a color balance mean value of a large number of negative images of the same type is detected and a weighted mean value of a color balance mean value among a plurality of negative images to be exposed and the detected color balance value to obtain a color control amount (Step 222).

Abstract: A color copying apparatus for constantly obtaining a high-quality print irrespective of a change in film characteristics due to deterioration is disclosed. 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.

Abstract: A photographic printer effects a second printing operation for one original frame (60) on a developed photo film (10), after a first printing operation is effected. First correcting information is used in the first printing operation for correcting an exposure amount of the original frame. To produce a photographic print, first and second equipment information is predetermined, which is associated respectively with the first and second printing operations. The first and second equipment information represents an ID of each photographic printer for effecting the first and second printing operation, or represents an ID of a printer group to which each printer belongs. The first correcting information of the original frame and the first equipment information is written to a magnetic recording layer (10c) in the first printing operation. The magnetic recording layer is formed on the photo film.

Abstract: A digital image recording method is to make high quality positive reproduction images from any types of originals by processing image data of each original based on an image characteristic value such as an average density of a prime subject portion of the original, which is derived from the image data. A basic image recording amount, which is used for every pixel, is determined based on the image characteristic value. Based on the basic image recording amount and a value of image data assigned to a pixel, recording data of that pixel is determined, and the recording data is converted into an image control amount with reference to a look-up table. The image control amount is used in an image recording device for recording the reproduction image.

Abstract: A color copying apparatus for constantly obtaining a high-quality print irrespective of a change in film characteristics due to deterioration over time and the like is disclosed. A reference image recorded on the film is photometrically measured to determine film characteristic data. After logarithmically transformed values of photometric values of an original image on one film set in a printing position have been stored, normalizing conditions are determined on the basis of average image data, and a transformation formula or table for transformation between the film characteristic data and image data 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 is made to correspond to print characteristic data by means of the transformation formula or table.
