摘要
An image processing device for two-dimensional raster images is described. The receiving means thereof are followed by a sub-sampling circuit (28) for increasing the pitch of the raster received in accordance with an adjustable scale. To the sub-sampling circuit there are connected a buffer (30, 32) and a correlation circuit (36, 38) for comparing a number of columns of pixels with a reference image. The comparison result is subjected to a logic operation. The device is suitable for modular use and may include a growth circuit for converting rasters portions onto one color or brightness when a predetermined minimum number of pixels therein contains the relevant color or brightness, respectively.
