  • Patent number: 7046343
    Abstract: A read-out image is acquired by covering an image storage sheet, which contains a color image, with an image storage sheet pushing surface of a platen cover and reading out an image of a region on the image storage sheet pushing surface of the platen cover, the region on the image storage sheet pushing surface containing the image storage sheet. A region corresponding to the image storage sheet in the read-out image is then recognized. The image storage sheet pushing surface of the platen cover has a color other than colors which are ordinarily contained in image storage sheets. The region corresponding to the image storage sheet is recognized by judging that a pixel in the read-out image, which pixel represents a color different from the color of the image storage sheet pushing surface of the platen cover, is a pixel falling within the region corresponding to the image storage sheet.

  • Patent number: 6038011
    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.

  • Patent number: 5404196
    Abstract: A method of making photographic prints wherein photographic data relating to photographic conditions of an original frame is recorded on a photographic film at the time of photographing the original frame, so as to determine the print exposure amount for printing the original frame. When it is determined with reference to the photographic data that a primary subject of the original frame has a proper density on the photographic film, the original frame is printed at a basic print exposure amount which is determined without using density data of the original frame. If it is determined with reference to the photographic data that the basic print exposure amount should be corrected for the original frame, an exposure correction amount is calculated based on the photographic data and/or the density data of the original frame.

  • Patent number: 5223892
    Abstract: 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.

  • Patent number: 5168303
    Abstract: 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.
