摘要：
An image processing apparatus comprises an input device for inputting an image data, a first converter circuit for converting the input image signal to an analog image output and a second converter circuit for converting the input image data to a digital image output. The first converter circuit controls the analog image output in accordance with the output of the second converter circuit. The second converter circuit produces different digital signals in accordance with the input image data and has a threshold matrix to be compared with the input image data.
