Abstract
Each recording pixel is divided into M small divisions where M is an integer of not less than 2. A threshold pattern is provided for the small divisions where a threshold value is assigned to each of the M small divisions corresponding to each recording pixel. The threshold values assigned to the M small divisions are compared with a multi-tone image signal to produce M pieces of binary comparison results. An image recording signal is generated as a function of a sum n of the M pieces of binary comparison results.
