  • Patent number: 6525840
    Abstract: In an image forming apparatus provided with an exposing section and a conveyor for conveying a plurality of light sensitive materials relative to the exposing section, the plurality of light sensitive materials are arranged in parallel in the conveying direction so that the exposing section is divided into plural exposing blocks corresponding to the plurality of light sensitive materials. There are provided a memory to memorize plural correction amounts each set based on a characteristic of one of the plurality of light sensitive materials, wherein the plural correction amounts are correlated with the plural exposing blocks in accordance with the corresponding light sensitive material; and a correcting section to correct the amount of light for each exposing block on the basis of the corresponding correction amount.

  • Patent number: 6297872
    Abstract: An image reading apparatus includes: a size detector for detecting a first size of a first image recorded on an original; an input device for inputting a second size of a second image to be recorded on a recording medium by an image recording apparatus; a determining device for determining a reading condition to read the first image according to the first and second sizes; and a reading device for reading the first image according to the reading condition to obtain information of the first image.

  • Patent number: 6222613
    Abstract: A method and apparatus for processing image information coming from various types of image inputting media yields an image processor for processing image information that consolidates image size irrespective of the type of image inputting medium. The apparatus is provided with a plurality of image inputting media, each of which inputs image information as a first image information having a fixed image size. An image size converter converts the fixed image size to a predetermined image size which is a constant image size independent of both the fixed image size and the type of image inputting medium that inputs the first image information. The conversion generates a second image information and a data generator generates conditional data for processing the second image information. An image processor processes the second image information using predetermined image processing procedures, based on the conditional data, to generate a third image information.

  • Patent number: 6081317
    Abstract: An image reproducing method includes a step of obtaining a print reproducing an object based on image information obtained by photographing the object, wherein logarithm E of object brightness satisfies formula (1) and formula (2) is effected with the logarithm E,D(E1).ltoreq.D(E).ltoreq.D(E2) (1)0.7.ltoreq.(D(E+0.1)-D(E))/0.1.ltoreq.1.3 (2)wherein D(E) represents density on the print reproduced by the logarithm E of object brightness, Dmin represents minimum density reproduced on the print, and D(E1) and D(E2) satisfy the following formulas.D(E1)=Dmin+0.15D(E2)=Dmin+0.

  • Patent number: 5210570
    Abstract: A method for determining an exposure for printing an original image of a photographic film onto a photographic paper. The method includes the steps of; scanning an image on a photographic film to obtain an image data; obtaining plural region characteristic values which includes a maximum density value, a minimum density value, and an average density value in each of plural areas of an image for example; obtaining plural image characteristic values from the region characteristic values; calculating a linear first order sum of the image characteristic values; and selecting one of plural predetermined sets according to the result of the calculating step. The exposure is determined with the regression equation predetermined for one of the predetermined sets.
