ABSTRACT:
An image processor for reproducing a continuous tone image such as a photograph in a black-and-white binary dot image (halftone image) has a linear correction section for converting a sampled digital image signal in a predetermined manner controlled by black and white densities of an original, thereby performing linear conversion between the continuous tone image and the halftone image. The image processor also has another correction section for performing profile emphasis to obtain a clear halftone image.
