PURPOSE:To correct the turbulence or the irregularity or the like in a dot and improve the picture quality of a dot picture by counting the number of black picture elements in dot data and generating a dot pattern corresponding to the number of the picture elements. CONSTITUTION:In a dot forming circuit 1, a threshold level is compared with a picture element signal level at the position, a blackening and a whitening processings are performed to form the dot and the dot is outputted as bit serial dot data A. At the same time, an affective signal B for indicating the range of one dot data is outputted. A black counting circuit 2 inputs the dot data A and the effective signal B to count the number of the black picture elements in the one dot and outputs the total number D of the black elements in the one dot. A dot pattern generating circuit 4 inputs the total number D of the black picture elements, and address information E from an address generating circuit 3 to generate the dot pattern F and output.
