ABSTRACT:
An image processing apparatus includes a feature data extracting circuit for detecting feature data indicative of density characteristics of a document based on image signals inputted from an input terminal, a density correction table selecting circuit composed of a neural circuit network which is learned beforehand so as to recognize image characteristics based on the feature data, and a density correcting circuit for selecting a density correction table in accordance with image characteristics based on a selection signal from the density correction table selecting circuit so that the density of image signals is corrected based on the density correction table. As a result, characteristics of the document are extracted, so that the density of the image signals can be corrected based thereon. As a result, the density characteristics of the document are extracted, and a density correction can be performed based on the extracted density characteristics, thereby obtaining a high quality recorded image with respect to documents of various kinds. Furthermore, by adopting the neural circuit network, the density of the image signals can be corrected accurately at high speed.
