Claim One:
1. A digital image processor for processing input image data based upon a cellular neural network, comprising: first multiply-and-accumulate arithmetic means for digitally processing multiplication and accumulation of input image data of a plurality of pixels and input weighting values in a predetermined area; second multiply-and-accumulate arithmetic means for digitally processing multiplication and accumulation of output image data of a plurality of pixels and output weighting values in a predetermined area; non-linear acting means for deciding output image data in accordance with results of processing from said first and second multiply-and-accumulate arithmetic means and non-linear characteristic parameters; parameter selecting means for selecting input weighting values used by said first multiply-and-accumulate arithmetic means, output weighting values used by said second multiply-and-accumulate arithmetic means and non-linear characteristics parameters used by said non-linear acting means, wherein various types of image processing can be executed selectively in accordance with the selected input weighting values, output weighting values and non-linear characteristic parameters; and offset input means for entering a predetermined offset value, wherein said non-linear acting means decides output image data in accordance with results of processing from said first and second multiply-and-accumulate arithmetic means, said entered offset value and the non-linear characteristic parameters.
