| abstract | (57) [Summary] [Problem] To perform error diffusion calculation, since the accumulated value of diffused errors is stored in a memory, if the range of error diffusion is widened, the number of memory accesses increases, and a long time is required for processing. Cost me. SOLUTION: When buffers MB and SB having a register capable of high-speed access are provided, and a dot on / off is determined for a pixel of interest P and a density error erw is calculated, this is shifted by a shift register SR. A weight density error erws is obtained. This density error er ws is output to each of the buffers MB and SB, where it is accumulated with the density error obtained so far, and each time the pixel of interest moves, the output of each buffer is shifted to the next stage. As a result, the number of accesses to the SRAM 16, which is a low-speed memory, is suppressed to twice per pixel, and the error diffusion process can be sped up. |
