  • Patent number: 7154614
    Abstract: In a device (1) for writing image information onto recording material (2), several separate images (B1 to B13) are assigned to the image information. Marks (M1 to M14) that are assigned to the several images (B1 to B13) are applied to the recording material (2) with a marking means (3). An output unit (4) is used for outputting the image information onto the recording material (2). Using a first transport means (5), the recording material (2) is transported in the area of the marking means (3). A second transport means (6) serves to transport the recording material (2) in the area of the output unit (4). The first transport means (5) and the second transport means (6) are designed such that the transport direction (T4, R4) of the recording material in the output unit (4) can be set independently of the transport of the recording material (2) in the marking means (3).

  • Patent number: 7154623
    Abstract: Apparatus (1) for generating images includes a reading device (2, 7), an output device (22, 26), a sorting device (9) and a control device (21). Image information of several images (A1 to A6, AX, AY) is read from input media and image data is produced that contains the read image information. The input media are assigned to several image production orders. Using the output device (22, 26), the image information that has been transferred to this device is output onto recording material. The input media are physically sorted in the sorting device (9) by order according to at least one prescribed criterion. Using the control device (21) the sequence for transferring the image data of images can then be determined in dependence upon the previously carried out sorting by order of the read input media.

  • Patent number: 6867847
    Abstract: In an apparatus for producing images on a light-sensitive material, the graphic information content for an image that is to be projected onto the light-sensitive material is divided into individual pixels. The projected image is composed of mutually offset partial images that are represented in a transmissive device consisting of an array of transmissive elements. The apparatus includes a light source that generates light rays passing through the transmissive device, an illumination device that bundles the light rays into light beams before they pass through the transmissive device, and a projection objective that projects the light beams telecentrically onto the light-sensitive material.

  • Patent number: 6864952
    Abstract: Images being processed in a photographic laboratory system into different forms of output are automatically evaluated to determine for each image whether it is of sufficient quality to merit processing into a selected form of output. Each image is individually evaluated by determining a grade value for each of one or more characteristic properties of the image, by assigning a target value to each of the characteristic image properties relative to each available form of output, and by comparing the grade value to the target value for a selected form of output.

  • Patent number: 6858861
    Abstract: An apparatus for reading information stored in a memory phosphor has a detecting device with an array of radiation-sensitive surface segments which during a pre-settable integration time interval receive a secondary radiation emitted by the memory phosphor. The apparatus includes a controller device that sets the integration time interval dependent on an amount of secondary radiation that was received at a preceding time. The controller device can also connect the radiation-sensitive surface segments into groups whose size depends on the amount of secondary radiation that was received at a preceding time.

  • Publication number: 20040263818
    Abstract: An apparatus for optically projecting pixel-based image information onto a light-sensitive material (12) has an image generator (1) for physically representing the image information in the form of monochrome partial images in different exposure colors. A projected image of the physical representation is produced by an optical projection device (4) which includes an offsetting device (7, 38, 39, 38a, 39a, 38c, 39c) for laterally offsetting the projected image in the image plane of the apparatus. The offsetting device is controlled by a controller means in a manner that is dependent on the exposure color of the monochrome partial image currently being produced by the image generator.

  • Publication number: 20040218165
    Abstract: An image in the form of image dots produced by one or more pixel generators is projected onto a light-sensitive material with a certain amount of light power over a certain length of exposure time. Each pixel generator is driven by a voltage of periodically alternating polarity which alternates between half-periods of negative voltage and half-periods of positive voltage, with the negative voltage and the positive voltage being equal in absolute magnitude. The exposure time for each image dot is allocated equally to the respective half-periods of negative and positive voltage.

  • Patent number: 6809795
    Abstract: The invention relates to an exposure device for exposing a transparent photographic original and reproducing said photographic original (2) on photosensitive material or by means of a recording device. The exposure device has a primary light source (1) comprising a number of elements that emit light of different spectral bands, whose light travels to the photographic original along a first optical path or can be directed onto the photographic original using optical elements. The exposure device has additional real and/or virtual light sources, (15, 16, 17, 18, 22, 24, 26, 28,) whose light strikes the photographic original along additional optical paths, or can be directed onto the photographic original using optical elements. The light that falls along the additional optical paths strikes the photographic original (2) at different angles of incidence from the angle of incidence of the first optical path.

  • Publication number: 20040012677
    Abstract: The present invention relates to an apparatus and method for processing the images (B1-B7) of a photographic order. The image processing is controlled by a control means (SM). Determination means (FM) determines the presence or absence of at least one selected property (PAN, RA, DCD) of at least one of the images (B1-B7) of the photographic order. Sorting means (AS) automatically rejects an image (B1-B7) from the image processing procedure in the event that the presence or absence of the selected property (PAN, RA, DCD) cannot be determined unambiguously.
