Abstract: A method for controlling a scanning apparatus for scanning a continuously moved object includes seizing the actual momentary position of the moving object, and controlling the time instant or period in which image information is captured by the scanning devices in dependence of the actual momentary position of the object. The scanning apparatus in which the method is used includes a multiplicity of line scanning devices arranged adjacent to each other in the direction of the movement of the moved object. Each of the line scanning devices has a multiplicity of pixels that are arranged adjacent to each other in a direction across a path along which the object is moved. The pixels of the line scanning devices accumulate charges according to the amount of incident light. A controlling means is provided for transferring the charges accumulated in individual pixels to pixels in the adjacent line scanning device in synchronism with direction of the movement and the speed of the moving object.

Abstract: A method for focussing a film scanner provides for selecting a plurality of partial regions of the picture to be scanned for the purpose of focus monitoring. During the focussing of one of the selected partial regions, the focussing of the other partial regions is simultaneously monitored. The monitoring is effected for example by simultaneous representation of the partial regions on a monitor screen, and/or by evaluation of the frequency and amplitude conditions of the partial regions. An optimum focal point is set if all the selected partial regions are simultaneously set sharply.

Abstract: A device for transilluminating a film has a light exit emitting with a light beam for transilluminating the film, a transillumination region for guiding the film such that the light beam can transilluminate the film in the transillumination region, a film feed for feeding the film to the transillumination region and a film removal for removing the film from the transillumination region. The device moreover includes a hollow chamber with a diffusely reflecting inner surface and a light entrance opening receiving light from a light source and an exit opening, as well as an optical guide having a beam entrance end and a beam exit end. The beam entrance end is arranged such that light exiting from the exit opening of the hollow chamber at least partially enters through the beam entrance end into the optical guide.

Abstract: An apparatus for transilluminating a film includes a light source emitting a light beam for transilluminating the film, a film guide for guiding the film such that the light beam can transilluminate a section of the film, a film feed for feeding the film to the film guide, and a film removal for removing the film from the film guide. The film guide has a support designed for rotation about a rotation axis running through the center of the support and a rotationally symmetric circumferential surface. The film can be supported on the circumferential surface at least with part of the width thereof over a section of the circumferential surface. The light beam generated by the light source passes through the film when the film is supported on the circumferential surface at least with part of the width thereof over a section of the circumferential surface.

Abstract: A film exposer has a modulator which modulates light from a light source and projects it onto a light-sensitive film guided continuously past the modulator. The modulator comprises a two-dimensional arrangement of elements which each project a specific quantity of light onto the film. A pixel entering the projection area of the modulator of the film on one side integrates the light which is projected onto the pixel by elements arranged in a row in the transport direction of the film. The quantity of light integrated by the pixel depends on how many elements are switched on, that is to say project light onto the film, while the film passes through the projection area of the modulator. The total quantity of the light to be integrated can be adjusted for each pixel by appropriate control of the elements respectively lying in a row in the transport direction of the film.

Abstract: A method for digitizing images stored on film material has, after the image conversion by means of a digitizing device firstly an electronic color value correction independent of user inputs. A user-controllable correction and manipulation of the electronically stored information is subsequently carried out only after the electronic color value correction, which is effected in a manner dependent on properties of the digitizing device and on film material properties. The electronic color value correction depends on parameters which can be adapted to varying properties of the digitizing device. A film scanner adapted to this method has a digitizing device and also a device for controllable correction of the converted image data. A device of discrete construction for electronic color value correction is connected between the digitizing device and the device for controllable correction.

Abstract: What is proposed is a method for the color correction of digital image data generated by spectral absorption of white light in color filters of a first representation means. Color film material, in particular, is taken into consideration as the first representation means. For this purpose, firstly the primary color values R, G, B of the image data on the color film are detected. Said primary color values R, G, B are corrected in order to generate secondary color values R?, G?, B? which are related to a second representation means, for example a monitor. This correction involves taking account of the absorption of light in secondary densities of the colorants of the film material which form the color filters of the first representation means. For this purpose, a plurality of absorption spectra are generated for different densities of the colorants.
