Abstract

A large image is printed by separately printing sub-images for subsequent assembly, the sub-images being printed under control of image representative signals which have been stored and processed to divide the image into blocks, preferably strips. Printing may be on a length of material such as paper, typically wallpaper width, by any method such as air brush, ink jet and laser printing. The processing may include enlargement or reduction in size of the image. The image representative signals may be generated by a computer, by scanning for example an object or photograph or by reading from a digital storage medium. The invention enables generation of large images without the requirement for printing apparatus of similar large size. <IMAGE>

Description

GIANT IMAGE PRINTING BY COMPUTER This invention relates to the use of a computer to print giant images in convenient sections.
Large images such as produced for bill-boards and hoardings are normally produced by conventional printing methods inappropriate on the grounds of cost for one off use.
Production of giant images photographically is limited by the size of photographic paper available and the difficulty of processing and handling such large sheets.
This is for the production of giant sized photographic or computer generated images on paper (or other sheet material ) on a one off or short run basis, using a computer to divide the image into convenient sections. The resulting image sections are as a result easily transported and assembled on wall or board in a similar manner to wallpaper hanging, and trimmed as required.
According to the present invention there is provided image processing apparatus comprising storage means operable to store data representing an image, processing means operable to divide the stored data into blocks representing respective regions of the said image, the transfer means operable to transfer the data blocks to printing means.
Preferably the data is stored in digital form.
Preferably the apparatus comprises image reading means operable to visually read an image on, for example, a photograph, drawing, painting, object and the like, and produce corresponding data for storage in the storage means.
Alternatively, the apparatus may comprise data reading means operable to read data corresponding to an image and stored on a storage medium, for example, a computer disc,tape, memory or the like.
The storage means may store the image as a pixel array or in any other suitable form.
Preferably the blocks correspond to substantially similarly sized regions of the image.
The transfer means may transfer the blocks of data individually to the printing means.
Preferably the printing means prints each region of the image individually according to the corresponding block of data. Preferably each region of the image is a strip across or down the image.
Preferably the printing means prints successive regions of the image along a length of material, for instance paper.
The printing means may comprise an air brush, ink jet, laser or any other printing method. The processing means may comprise a computer.
The apparatus may comprise enlarging and/or reducing means to permit enlargement snd/or reduction of the size of the printed image relative to the image represented by the data stored in the storage means.
Further according to the present invention there is provided a method of processing an image, the method comprising storing data representing an image in storage means, processing the image data to divide the data into a plurality of blocks representing respective regions of the said image, and transferring the blocks of data to printing means.
Preferably the data is stored in digital form.
Preferably the method further comprises reading the image using reading means as aforesaid to convert the image into corresponding data for storage.
Alternatively, previously stored data corresponding to an image may be read from a storage medium such as a computer disc, tape or any other suitable medium.
Preferably the blocks correspond to regions of the image of similar size.
The blocks of data are preferably outputted from thedata processing means to printing means operable to print regions of the image, preferably sequentially. The blocks of data may be transferred individually to the printing means.Preferably the parts are printed along the length of strip material, such as paper.Preferably the regions are strips across or down the image.
The printed image may be printed in a different size relative to the image represented by the stored data, by use of enlarging and/or reducing means provided in the apparatus. Preferably the printed image is enlarged relative to the original image.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing.
Referring to the drawing, t is the original image that is transferred via the scanner and into the computer. 2 is the computer generated image. Either the original image 1 or the computer generated image 2 is transferred to the computer where 3 the digitised image is in the computer memory.This becomes a digitised image logically or physically divided into strips within the computer 4 The paper 5 which is typically wallpaper width has the image printed by computer. The computer prints the image sections sequentially 6 Waste paper 7 can then be trimmed when the image is mounted.
The digitised photographic or computer generated images would be stored within the memory of a computer system as a pixel array or any other method.
The computer would then divide the image into manageable strips representing wallpaper width (or other convenient width sections ).
The computer would output the image sections to a printer using any computer driven printing method, in vertical or horizontal sections allowing a single width of printer and paper to be used irrespective of the size of the required image.
