Method for image reproduction with variable magnification

摘要

This method, in which an image information signal for recording an image on an image carrier is converted into an electrical signal by means of a scanning system, is characterised by the fact that a magnification or reduction in image size is carried out at least in the main scanning direction and/or in the secondary scanning direction in accordance with one of the method steps A) or B) below for main scanning direction and, respectively, one of the method steps A) or C) below for secondary scanning direction A) Scanning of an image form or imaging signal with a frequency or a scanning start signal; B) Selective use of a number of image reproduction devices, which are provided in accordance with predetermined variable magnification ratios, by means of a selection device for changing the ratio of change of the recording size; and C) Change of the main scanning period of the image form or imaging signal. In this context, either a change in the relative speed of movement of an optical scanning device with respect to the original image or a change in the speed of movement of a charge carrier element can be selected in addition to the method steps in the secondary scanning direction of the original image.
