<p>In a typical frame store for a raster scanned image, image data is stored in a memory element row-wise, i.e. as the image is scanned the pixels in each row are stored sequentially in the RAM. The invention provides a novel method of storing such data wherein the data is stored column wise in a plurality of memory elements, i.e. as data from an image is scanned in rows the value of the pixels in certain columns are stored in each memory element such that after receipt of a complete field or frame each memory element contains the data of one or more columns of the image. By having a plurality of memory elements data may be read out simultaneously from each element and thus the data can be processed more quickly than with conventional systems.</p> |
