Abstract: PURPOSE:To prevent the generation of a false contour by expressing changes in the density with a gradual frequency of generating dark and light dots in the size enough to reproduce virtually the same reflectively optical density so as to ensure the continuity in the densith and texture. CONSTITUTION:Various color signals from a line memory are converted into signals Y, M and C in recording color densities with a masking circuit 41 and a color-less component K is extracted with a ground color removing circuit 42 to obtain actual recording color signals Y', M', C' and K. Then, signals are outputted from color patterns generators 43-46 to drive respective heads for large light dots and small dark dots virtually the same in the reflectively optical density to form one pixel with 4 dots. The switching of fine cells within one pixel for changing the frequency of generating dots different in the density is done by a clock signal CL for driving the carriage. This ensures the continuity in not only the density but also the texture to prevent the generation of a false contour thereby producing an image of a high grading property with a high quality.

CONSTITUTION: When the sampling is attained in the horizontal scanning direction, a switch 44 is connected to the position of terminal (a). Then, a desired sample pulse is obtained at 1H by PLL circuits 39, 40 from a horizontal synchronizing signal H.
