Abstract

PURPOSE:To give a compensation to the disturbance of the pattern caused by the thinning, by performing the thinning and reduction after giving an interpolation process to the specified 2X2 dot pattern. CONSTITUTION:The pattern signal of the original pattern is trnsferred to the input register 22 and the data registers 23-25 from the reading part 21. And a shift is given so that the intersection of the thinning line and row may be positioned at the center position of the pattern register 26 formed with the 3X3 dots. Here in case the dot at the diagonal position to the intersection is white and the two dots at the adjacent positions are black, the compensation process part 27 corrects the white dot at the diagonal position to the black dot. Then the compensation process part 26 gives the input again to the registers 23-25 after compensation, and then the thinning is carried out at the thinning process part 28. Then the recording is carried out at the recording part 30 via the output register 29. Thus a compensation process is given to the specified dot pattern to ensure a compensation to the disturbance of the pattern caused by the thinning and reduction.
