Abstract
An image data processing system for use with an image input device of a facsimile apparatus, digital copier, computer or the like. By using the fact that both MTF compensation processing said scanning line density conversion processing are represented by a sum of products of peripheral pixels and coefficients, i.e., linear product of peripheral pixels, the system adequately selects values of the coefficients to simultaneously effect MTF compensation processing and scanning line density conversion processing by way of the same architecture.
