摘要:
An apparatus and method is disclosed for digitally reproducing images on photographic film. A main scanning element scans at least one image of the film during a main scanning operation and produces main scanning values from which at least one film-specific characteristic value can be obtained. Image processing means are provided for modifying the main scanning values on the basis of the film-specific characteristic values determined, at least one part of said main scanning values comprising main scanning values of at least two individual images.

A method of producing a pixel-based image on an image carrier (7), where a plurality of pixels are generated simultaneously by an array of pixel-generating elements, has the following steps: producing on the image carrier a first partial image composed of first pixels, wherein each of the pixel-generating elements is assigned to produce one of the first pixels, and wherein the first pixels are spaced apart from each other, and producing on the image carrier at least one further partial image composed of further pixels in such a manner that the further pixels fall into the spaces between the first pixels, but none of the further pixels is generated by a pixel-generating element that has produced one of the adjacent first pixels.

An apparatus for optically projecting pixel-based image information onto a light-sensitive material has an image-generating device, an optical projection device, and a device for laterally offsetting the projected image of the image-generating device to produce a plurality of mutually offset partial images in the image plane. The offsetting device has two optical elements arranged in sequence in the light path of the projection. The projected partial images are offset relative to each other by tilting one or both of the optical elements.

A device for removing moisture from individual sheets of a photographic material has a pair of transport rollers at the incoming side and another pair of transport rollers at the exit side of the device. Arranged between the roller pairs is a squeeze-out surface with a wiper blade set against the squeeze-out surface.

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.

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.
摘要:
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.

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.
摘要:
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.
