Abstract
An image transcribing system for transferring an image from an original document to a recording sheet in which the original image is scanned, converted to binary signals and stored in a first page memory. An image processing section transfers the image data from the first page memory to a second page memory while it is simultaneously enlarged by a predetermined factor. In the enlargement process, the image data is first enlarged by an integer factor then reduced by a fractional factor in accordance with stored bit patterns corresponding to the required fractional factor.
Claims6
An image transcribing device comprising;
- an image input portion for scanning an original document for converting an image on the original document into binary binary information signals representing the image, a first page memory for storing said binary information signals, a second page memory, an image processing section for transferring the binary information stored in said first page memory at addresses corresponding to a predetermined region of the original document to the second page memory and stored at addresses corresponding to a predetermined transcribing region for a reproduced image, a recording section for copy reproducing the stored binary information of said second page memory on a recording sheet, means for observing the image on the original for selecting the predetermined region of the original document and for assigning a position on a recording sheet at which the image is to be transcribed, and means for generating addresses corresponding to said predetermined transcribing region from said assigned position.
An image enlargement and reduction system wherein an original image is subjected to a main scanning and a secondary scanning for conversion to a time sequence binary electric signal, the binary electric signal being thereafter processed so as to obtain an enlargement or reduction of the original image, comprising means for enlarging the original image by factor of a natural number constituting the sum of the integer part of a desired enlargement factor and a predetermined natural number, and means for reducing the enlarged image by a factor equal to the ratio of said sum to the desired enlargement factor to thereby obtain an image enlarged by the desired enlargement factor.
